Introduction to thermal insulation water tank

What is the insulation water tank

The insulation water tank refers to the addition of special industries and thermal insulation materials in the mezzanine of the water tank, so that the water tank must maintain a certain temperature to meet the needs of life or industrial.The insulation water tank can be divided into: stainless steel insulation water tank, pressure insulation water tank, and glass fiber reinforcement heating water tank according to the different processing materials.

The principle and structural diagram of thermal insulation water tank

The insulation water tank refers to a kind of insulation material used in the inside of the insulation cup to make the core layer, and then use the stainless steel water tank as the inner surface layer, and the outer layer is made of ordinary stainless steel plates.The combination of these three materials is the most suitable and best combination. In this way, the stainless steel insulation water tank is initially formed.Therefore, the insulation water tank is composed of three layers, the core layer, inner layer and outer layer.

The insulation medium of the core layer can be insulated by 50mm or 80mm polyurethane foam, polystyrene, PEF, etc.The inner layer is a stainless steel layer, so it is necessary to use a better -quality SUS304 food -grade stainless steel plate and galvanized plate.Finally, the outer layer is generally selected by the relatively ordinary stainless steel punching film block or a tablet. You can choose SUS304 stainless steel or SUS201 stainless steel for production! The thickness of the water tank board can be determined according to the size and height of the water tank.Of course, the material for insulation can also be used to choose asbestos or rock wools for insulation.

The insulation water tank hot water is out of the hot water

under.The insulation water tank consists of three parts: high water tank, depository and low water tank.The high water tank is equipped with a mechanical controlling water moisturizer, flushing valve and water leak valve, and electrode floating sub -switch. The valve seats of the water moisturizer and flushing valve are connected to the three -way flushing pipes set in the storage tank.Open the valve, connect the high water tank with the water storage tank; set up leveraged float switches in the low water tank, open the float valve core, connect the water tank with the low water tank; there are also submersible pumps, filters and sewage pipes in the low water tank, submersible pump out of the water pipe out of the water tankThe mouth is located in the high water tank, and the closure of the submersible pump is controlled by the electrode float switch in the high water tank.

How long can you keep the insulation in the thermal insulation?

Looking at the performance of the insulation water tank, at room temperature (20-30 degrees), the thermal insulation water tanks dropped by about five degrees within 24 hours. The lower the external temperature, the lower the temperature decrease of the water temperature.

Insulation water tank classification

Stainless steel insulation water tank

Advantages: high strength, good sealability, never leakage; light weight, convenient assembly; high corrosion resistance, never rust.

Disadvantages: The technical requirements are very high. If the technology is not comprehensive, or if the design is not good, the corrosion will occur, and the leakage will occur; the metal ions in the stainless steel will also affect the water quality.

Pressure insulation tank

Advantages: It is mainly divided into enamel water tanks and stainless steel pressure tanks; enamel water tanks are not easy to be corroded; stainless steel pressing water tanks will be very durable as long as the anti -corrosion problem is solved, and the overall is very light, convenient for transportation. At the same time, it can be designed in the overall structure.More big.

Disadvantages: As long as the temperature difference between enamel water tanks changes, porcelain will be dropped, and the water tank cannot be done too much, and there are certain problems in the handling of the transportation.If the design is not good, the corrosion will occur, and leakage will occur.

FRP insulation water tank

Advantages: easy installation, saving space, no leakage, light weight, high strength, impact resistance, bending, easy repair.

Disadvantages: It can only be stored in warm water and cannot store hot water; the sealing is not good enough, and it is easy to produce secondary pollution; the service life is short, and it is prone to cracks when using 1.5-3.5 years.

Solar insulation water tank

Advantages: The system has good thermal insulation. As long as there is hot water in the water tank, the phenomenon of heat and coldness will not occur; if the service life is long, the use of reasonable life can be as long as 15 years.

Disadvantages: The requirements for the installation location are very strict. If the installation is improper, there will be hidden safety hazards.Hours of hot water supply, poor comfort.

Thermal insulation water tank price

Generally, the price of heating water tanks from 0.5T-10T is more than 1,000 yuan-9,000 yuan. The larger the volume, the larger the capacity, the more expensive the price, and the price is different from the thickness of the insulation layer, the material of the inner and outer Skin, and the price is also different.

Self -made insulation water tank

What materials need

Stainless steel insulation water tank insulation material: Core layer medium can use polyurethane foam, polystyrene, polybionenitine, rock wool, PEF.The inner layer can be used for food -grade stainless steel plates, galvanized plates, aluminum plates or color steel plates.The outer layer can be made of stainless steel plates, galvanized plates, aluminum plates or color steel plates with general materials.

5.Start welding groove steel charities;

6.The bottom welding is completed and the floor is tied.

7.The assembly side plate is fixed in the welding method.One wall plate of the stitching side should be arranged in a flat on the edge of the bottom plate;

8.The stitching side second plate should be superimposed on the basis of the one -board side of the side. The position requirements of the ten seams of the wall plate, the level, flat;

9.Welding, the welding seam is required to be full and Smooth, and the oxidation of welding welding can not occur;

10.Test the leakage experiments using the internal inspection method outside to ensure the next step after the leakless leakage; add the internal pull -up support (the industry is collectively referred to as the tension). According to the calculation of the tensile forceItems

11.The cover plate is required to strengthen the welding reinforcement firmly;

12.Position in and out of the water outlet (the size of the pipe and place according to the requirements);

13.The fixed external insulation layer is made of stainless steel in 201, and the external insulation layer uses flame retardant polyurethane foam insulation layers. Welding fixing parts on the outer wall of the water tank, and then welding the insulation board.

14.In order to be beautiful, use the L -shaped corner edge and external welding joints to spray paint;

15.A brand new water tank has been completed.

[Wild fishing bait] How to make wild fishing bait formulas in the production of wild fishing bait

Wild fishing bait formula

1. Steamed buns: Make this bait is very simple: when fishing, use a plastic food bag to wrap a piece of steamed buns. The fresh, the better the size is.Peel, drip ten to twenty drops of wine controlled from the bait of the wine, and then add an appropriate amount of water in the fishing ground, and the soft and hard dough.Using this bait is not afraid of small miscellaneous fish nests, and the biggest benefit of this bait is that in the midsummer of the red sun, when the fish does not bite the hook, as long as there is fish in the nest, it is easy to leave this bait, it is easyThere are Fish hooks.

2. Take a house -raised firewood egg. Other eggs are followed by the effect, 30 grams of sugar, a moderate amount of Flour, and a slightly harder dough. Do not add water.Take a small rice tank of Xiaogan, you have to be polluted after drinking it, and there are rice tanks with rice wine on the tank wall. If there is no residual in the tank wall, add some rice wine when you have noodles.Put the dough into the tank and seal it with two to three layers of plastic. It must be sealed tightly, otherwise, the surface will have a sour taste, which is not easy to use.Under normal circumstances, use an egg and noodles, and can be used to fill the tank for two or three days, and it can be used at this time.When used, open the plastic cloth, there will be a mellow fragrance and sweetness of wine, and because of the fermentation, the surface will soften, add some Flour, and drop a few drops of sesame oil in it.EssenceThis bait, catfish, carp, grass carp love to eat.Used for Fertilizer and water fishing and wild fishing.

passUnifiedfishingbait

1. Fresh earthworms are equipped with hooks, shake the soil, dip in the dragon king hate musk liquid flavors, put in fishing spots, fishing catfish and carp, with outstanding effects.

2. The fermented oil residue of the sesame oil workshop is stinky and fragrant, mixed with noodles, tuned to hard and hard like earlobe, takes soybeans to hook, and special effects fishing chain.

3. Mix the corn surface and white surface, and use thickness and noodles to adjust to loosening.As needed, adjust it into bait, fishing, and bad food.Floating fishing, directly attacking the white chain, flower chain, and grass carp;

4. The leftovers of Kung Fu Tea, raised earthworms, earthworms have good momentum and rapid reproduction.fishing with the developed earthworms is several times more than ordinary earthworms.

5, Wheat bran, stir -fry; corn surface, fried; green corn kernels, crickets, stir -fried Wheat bran and corn surface, mix some white noodles in moderation, make mixed food, fishing carp, grass carp, and catfish.

6, soybean savory (can be in popcorn), grind into powder, used as dipping bait, carp fishing has special effects.Mix with two -point soybean Flour, three -point white noodles, and five -point corn surface, and cook with boiling water to make a bad food, fishing catfish and carp.

7, red heart grilled Sweet potato (white heart can also be), cut into sieve pieces, hook fishing catfish, and it is better to fish carp.Mix roast sweet potatoes and hot corn surfaces, can be made into bait, and can also be made into bad food.

8. Take the mint leaves by the river or reservoir, rub it with dried millet, sprinkle the fishing spots, seduce catfish with special effects, and avoid small miscellaneous fish.

How to make wild fishing bait

1. Plum Bud bait

One time fishing, I found a fish on the shore plant flowers.Back to the fishing position, I took two flowers buds and hung on the hook. It was very spiritual.Since then, I have tried it with other fishermen many times. It turns out that the use of pearl plum buds to fish for catfish during the summer is several times stronger than using pasta and earthworms.Pearl plum is a shrub, which has a long flowering period, and it can continue from mid -June to the end of September.During this period, it was a hot summer. The catfish had gradually entered the anorexia period. The interest in bait and pasta was greatly weakened. Facing the cool and fragrant pearl plum buds, they had special interests.

2. Sweet potato bait

Cook the sweet potatoes or steamed it to nest as bait.Because the cannon Sweet potato contains a lot of sugar, it has a natural sweetness, it is pale yellow, light red, carp, grass carp, cattle, catfish and so on.But use artillery sweet potatoes to make bait, remember not to be too familiar.It's too familiar to hang the fish hook, and it is easy to fall off; it is too familiar, Hanging the fish hook, but the tasteless, the fish does not ask.The most ideal method of making raw potato bait is to cut yellow potatoes with yellow or white -skinned red heart into two or several pieces, cook in the pot or steam it to seven or eight mature (cook for about 10 minutes), use a bamboo stick to a bamboo stick,It is better to poke when it is worn.

Third, puffed powder bait

There are often foods such as "walnut nutrition powder", "advanced protein nutritional powder", and "sesame paste". They can often smell a strong puffed smell with boiling water.The appetite of fish, grass, , etc.The main ingredients of the above -mentioned nutritional powder are puffed powder. Almost all food stores are available. It is very convenient to use it. It can be described as a good product for mermaids.Before use, a small bag of nutrient powder can be blended into groups with corn noodles, Flour, bean Flour, and finished bait powder.If you add a few drops of sesame oil to mix well, the effect is better.

Fourth, malt bait

Malt is rich in nutrition and sweet, rich in carotene and a large amount of vitamin E. Therefore, Chinese medicine often uses it to make appetizers.The folk also uses it to make maltose.

The length of the malt is 6-10 cm, and the content of vitamin C and A will be high. Usually at this time, fishermen use it as a feed for grass carp or carp.At this time, it is the most ideal bait with it to use it as a bait.Before fishing, pick some moderate maltza to make a 2 cm long, 1 cm diameter malt grass cluster hook, and its effect is significantly better than other bait.If you use this bait to fish carp, you can mash the malt as a nest as a bait, or you can mix it in other bait to fight the nest.

In addition, malt can also be used for floating grass carp.The method of cultivating malt is very simple. When the ambient temperature is 20 right, use warm water at 12-20 C, add a little salt, and soak Wheat grains for 24-8 hours.After its swelling, it is flourished in the porridge container, covering a few layers of wet gauze and placing it in a shelter. Spray 30 C of 30 C every day and night 3-4 times.After the germ, remove the cover, it can be used after 2-4 days.

Five, snail mussel bait

Buy snail meat from the market, crush it with a meat grinding machine, add it into the homemade bait, and you can throw fishing at will.

This bait is characterized by a large fishy smell, and carp likes it.The hook of snail mussel bait is firm and does not fall off. One bait can catch more tail fish, and it does not recruit small mixed Fish hooks.It is available in spring and summer and autumn. It is economical and convenient, and fishing and other fish.

Six, bait

Green maggots are widely survived on the leaves and stems and leaves of green vegetables, such as roll -hearted white, Chinese cabbage, greens, foreign cauliflower, etc., and the maggots are made of leaves, so the body color is green.

When vegetables grow as long as 40-60 days, the individual of green maggots is generally about 2 cm, which is the best stage for fishing.Before fishing, use a small box to fold a piece of vegetable leaves in the box, and you can catch the green maggots into the box one by one in the vegetable field. Because there is vegetable leaves attached, the green maggot will not climb out of the box. You can also use a small pill bottle.Playing, more convenient to carry.

Green maggot should be used on the same day, and it is easy to die for a long time.Beans are mainly attached to the pods in plants such as soybeans (also known as soybeans and black Beans).

Bean maggots have grown rapidly since the green soybean pods. When the soybeans are yellowed, it is also an adult individual, and its body is 0.5-1 cm in length.The color is slightly yellowish, which is slightly larger or similar than a grain of mung bean rice. At this time, collecting Beans fishing is the best bait. Because the bait is eaten with Beans, its smell is full of flavor, and it is easy to attract fish.hook.

Bean maggots are more tough than green maggots. Therefore, Hanging bait is more firm. The bait is clean and hygienic without polluting fingers.There are many kinds of Beans like green maggots.

Seven, broad bean Flour bait

First, choose good materials.Broad bean has three types of green Skin, white Skin, and red Skin. The green Skin is superior, and the white Skin and red Skin are grinded.

Secondly, go to the shell.There are two ways to remove the shell: one is to put the broad beans in the pot, and fry it with a micro -heat until a number point.Do not want to be cooked with broad beans, otherwise you will lose the smell of raw bean and lose sticky. Catfish do not like to eat.After the fried broad beans are cooled, peel off the shell with a small knife.The second is to use a crusher and remove it and remove the shell.Dry again.Dry the bean with a micro -fire, dry the broad beans, one is polished into powder, and the other is to store it well.

Fourth, it must be polished into powder.There are two ways: one is to play with stone mills and crushing machines.The finer the fans, the better the finer, the stronger the more sticky.You can push and play at 0.5 kg each time.The second is handmade grinding method.On the eve of the fishing, the bean of about 10 shells of the shell is grinded on the ground dumplings by hand, or clamped the broad beans with a clamp and grind them on the coarse sandpaper.In this way, the freshly grinding broad bean Flour has a strong smell of raw Beans and better effect.

Eight, mulberry bait

Choose a linked mulberry, and you should choose the 7-8 mature mulberry as a bait on the spot.When the hook is linked, the size of the mulberry depends on the fish in the river.If there are more fish and large heads, you should choose a larger fruit hook; if there are fewer fish, you should pick a mature small fruit, or half a hook (preferably cutting the knife).

It is okay to penetrate the tip penetration, and the fish is more likely to hook.Since the mulberry is mature to the end of the fruiting period, the mulberry falling from the mulberry tree by the fish is often moved to a fish in a section of waters near the tree, forming a partial eclipse.The fish in the surrounding waters are accustomed to falling fruit, and they generally do not stay away. As long as a few throws a few, they can attract.

one,How to buy a applicable binocular Telescope

Three directions of the consideration of the two -Tube Telescope without external diameter, magnification, and lens quality:

CaliberTheThe size (diameter or caliber) of the objective mirror (lens in front of the Telescope), The double -Tube Telescope on the market is used to use it20mmto70mmThe diameter is more common, such as the label on the Telescope12 x25Of25The representative diameter is25mm(2, 5Cm.,,12It represents its magnification, the larger the caliber, the larger the volume, and the light power of the caliber and the Telescope(Brightness) Calling portrait (clarity)There is a great relationship,12 x 25and12x50Two dual -microscopy is also the same12DoubleBut the latter's brightness and sharpness must be higher than the former.

When you consider the diameter of the dual -Tube Telescope, there are nothing more than two options:

1. If you are ornamental concerts, various ball competitions, mountain climbing, outing travel, etc. to facilitate the use of priority, it is best to choose small and medium -caliber (35mmthe following) The model, the size of the size is also light, but it is inevitable that the brightness and resolution will be sacrificed.

2. If it is astronomical observation, night or long -distance observation, etc. with high brightness and high -solution image as the first priority, choosing a larger caliber will be ideal.Most of the binocular Telescope already has a tripod fixed -hole design, which can be fixed on the average camera tripod. It can not only reduce the burden on both hands, but also greatly improve the stability.

High and lowTheGenerally, consumers mostly consider the multiplier when choosing a Telescope. The higher the ratio, the better. In fact, it is not correct. The high rate does not represent the clearer image and the caliber is larger.The biggest advantage of the Telescope is that it is easy to carry and has high maneuverability. If the long -distance observation requires a higher power rate, it is recommended to choose a single -Tube Telescope effect.

lens qualityTheThis item can be considered the most difficult to understand in the average person. A two -Tube Telescope optical part is:1. object mirror.2. Eye mirror.3. Prism.Combined, let's talk about it first:

1. object mirror:That is, the lens closest to the target of the two -set lens barrel at the front of the two sets of goggles. The image is directly related to the quality of the objective mirror. Generally, most of the products are combined with two lenses.The Telescope uses three combinations, or uses itED, Fluorite and other special material lenses to reduce the effects of color differences.

2. Eye mirror: When using a Telescope, the lens group near the eyes is called the eyepiece (left and right eyes), Typical eyepiece is composed of three optical lenses. The vision of the eyepiece itself is about50Around the degree, the actual field of vision is to divide the eye mirror vision. If the same multiplier twin Telescope mirror, if you want to have a large field of vision, and maintain a good image around the field of vision, you need more lenses, more complex design to correctThe price is relatively improved.

3. Prism:If there is only a combination of objective mirrors and eyepiece, the imaging of you see is reversed, so a set of positive prisms need to be added on the light path between the objective mirror and the eyepiece.In the normal direction, the material of prism is generallybak-7glass, higher -level models will choose high refractive indexesbak-4The prism makes the image brighter.The two -Tube Telescope design must be used with a roof spine prism(ROOF PRISM), the production is more difficult, and the price is usually relatively high.

The above optical common sense, I believe it will help, the last three principles for your reference when you choose:

First, when you consider carrying convenient carriers and choose small models, the multiplier rate should not be too high, otherwise you may be disappointed because the brightness is too low.

2. You must understand what the purpose of using a Telescope?It is the best choice of one that suits you need.

3. Find a professional company to tell your purpose and budget in detail. I believe that as long as you are a professional company, you will definitely give you a satisfactory service.

Second, the tips for buying a bilateral Telescope

1. Trip tips for buying a long -range optical effect

Generally, when we buy a Telescope, we will see the same specifications of the Telescope. The price is very different. This is mainly because the lens of our Telescope is different because it affects the quality of the Telescope optics.The brightness of the general Telescope is the highest, and the brighter it means that it can see further.

The better the lens coating, the more transparent the lens, the darker the reflective.There is also a red film Telescope. The red film of the lens not only increases the brightness of the Telescope, but also makes the imaging more similar. Everyone can also choose this type of Telescope.

2Functional purchaseTips

The internal nitrogen of the Telescope has a water effect, and it can also prevent the fog of the internal lenses and the mold. This is mainly because the Telescope is seal, so this increases the durability of the Telescope.Talk about the advantages and disadvantages of different prisms of the Telescope, generally there arePorroPrism and prismroofPrism.PorroAlthough the prism is large, the structure is simple, the light transmission rate is high, and the imaging quality is good.androofThe prism, although the volume is small, but the structure of the prism is complicated and the light transmission rate is low.

3. Buy a Telescope workmanship and materialTips

1. 1.It is made all plastic.

2.It is mixed with plastic and metal, and its main parts are made of metal materials.

3..It is made of all -metal. This is the best durability of the Telescope in the three materials.

1. What does ice hockey shoes mean?

After buying icehouse shoes, it usually needs to be blank. Many friends may not know what the blade means. In fact, the blade of ice hockey shoe refers to the first time the blade was grinded after buying the icehouse shoes.Stick the defects on the blade, form a sharp blade, and grind the inner and outer blades.

2. Is Ice Hockey's Blade?

need.

If the newly bought icehouse shoes, if the ice knife does not slide directly, the blade is "round" for a while (that is, it cannot be a right angle, with the arc), and then the blade is easy to open the knife (the left and right feet are intensive.Different, the degree of roundness is not the same, and then the blade is easy to open high and low feet). How expensive the Tube is, the new knife is required.

In addition, after the blade, it is not once and for all. If it is grinded for a while, it occurs that the ice is unstable and slippery, which means that the ice knife is needed to grind the knife.

3. What is the difference between ice hockey shoes and unspoken blade

Ice coat shoes are ice -knife shoes worn during ice hockey. They are the same as skating knife shoes and figure skating shoes. After buying, they need to make blades. Blade ice coal shoes and unshakable icehouse shoes are completely different.The differences between them are:

1. Different functional differences: Blade ice knife can skate. The ice knife without blade cannot skate and it is easy to fall.

2. Different effects: The blade of the ice knife can be strenuous on the ice, and the ice knife that is not blade is more blunt and cannot be worked hard.

3. Different appearance: The blade of the ice knife is more shiny and Smooth, and the ice knife that is not blade is relatively dull and dim.
