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.

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.

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.

1. Is the surfing board inflatable?

The surfing board does not need to be inflated.

The surfing plate is solid, and there are many manufacturing materials. Generally, it is made of tape with large buoyancy. The shape is rectangular in the front circle. The surface is Smooth and there are some raised in front. It cannot be inflated inside.

Water inflatable is floating bed or air cushion boat.

2. Where does the motivation of the surfing board come from

Speaking of surfing, friends who like the maritime project should like this. In the past, traditional surfing equipment relied on the wavy of sea water. However, with the development of technology, electric Surfboards have become emerging equipment.The biggest feature of this electric surfboard is that it can achieve the purpose of surfing through its own electric device without waves.

The power source of the electric surfboard is an Underwater propeller, and the rotation of the propeller is driven by a built -in lithium batteryIt can provide about 1 hour of kinetic energy. In addition to entertainment, this surfingboard also has the "rescue mode". Although it is strange and cool to use, the price really makes many people be expected to be inaccurate.It is reported that the retail price of such a surfboard is $ 5,000.

Although this kind of electric surfboard looks simple, it is very difficult to operate. For beginners, this surfingboard is not suitable. It is still practicing with traditional Surfboards. After mastering a certain skill, challenge the challenge.This cool water "Royal Sword Flying".

1. What are the classifications of folding chairs?

5. Try sitting: Try it in person to understand its comfort. You need to change each angle and buy it after confirmation.

Third, the correct way to use folding lounge chairs

Many families now like to go to the beach, not only beautiful scenery, but also children also like to play water.At this time, parents usually save effort.After the sea is enough, go to the chair on the beach to bask in the sun to eat, which is really comfortable.The comfort of the lounge chair is also a key element.

folding lounge chairs are one of the first choice for Outdoor leisure, because it has many advantages, such as: foldable, easy to carry, sitting or lying (when you want to squint) and so on.

There are many kinds of fabrics in folding lounge chairs. In fact, we are common in PVC mesh. We do nt know what to call when we see it. The biggest thing about the PVC mesh cloth is a bit of a thing.See how these advantages should know why we choose it.There are also some leather, cotton. These fabrics are more suitable for home use. Otherwise, the folded lounge chairs of these materials are easy to break out of Outdoor use. It is likely that it is likely that it will not want it when it is brought back.

As a yard, a folding lounge chair on the beach is generally used in the folding chair on the beach. It is generally a phosphorus steel pipe folding chair. It phosphrates the steel pipe through phosphorphyic fluid, making the anticorrosive effect higher than oxidation, and the beach is generally humid.And water is salty, so a folding chair of the phosphorus Tube is generally used in these places.

The folding chair of PVC mesh folding chairs and Oxford cloth is more suitable for people to fish, climb the mountain, use it in line, and you can open it at any time when you are tired.Is it very convenient?

The bamboo chair is very casual. When you put it at home, lie down, be tired, lie down, play tired, and lie.

Some folding chairs are suitable for lunch breaks in the unit, and the Hospital's lounge is also particularly suitable. Now there are more and more patients. Doctors have to work seriously at night.Isn't it good to put a folding chair that can be lying flat, you can squint for a while when you are tired.

How to buy a life jacket

1. Look at the fabric

There are generally two types of life -saving fabrics, one: special nylon material, which is relatively low in price and wide use, but not durable; the other is: neoprene choppen rubber (diving material)., Feel soft and comfortable, friction, as long as high -end life jackets can use this fabric.

2. Look at accessories

There are two types of life jacket accessories. One is the survival whistle. This is basically standard for life jackets. The other is reflector. If it is operating at sea and the visibility is low, we are strongly recommended to standard.If it is generally playing leisure and entertainment, it is generally not worthy.The life jackets of Big fish also attach many functions, such as pockets, fish tongs, sub -pockets, and so on.However, some of the life jackets are required. No matter how the style changes, these are not missing. This is the life pocket and insurance Belt (through the Belt connected to the front film from the back of the life jacket).

3. Look at buoyancy

The buoyancy of life -saving clothing should meet the prescribed standards (continuous soaking in seawater for 24 hours of buoyancy should not be less than 0.75 kg. The front and rear pieces of life jackets must have the correct proportion.The buoyancy is regarded as 1, and the buoyancy of the front film should be greater than 0.58).However, the buoyancy will change as the buoyant time in the water will change at about 5%.. Strong buoyancy, folding is convenient to collect in life jackets, and it is easy to dry. More importantly, the buoyancy is soaked in the water for a long time, and the cutting force is significantly reduced significantly.

4. Look at the reinforcement situation

Two methods are commonly used for life jackets.The first: rope, this kind of life jacket is generally a low -suspected life jacket.This is used in early life jackets.The second is zipper buckle. This kind of life jacket is the most widely used now.

5. Look at the color

In order to find the water falling in the sea, the color of the fabric of the general life jacket is more bright colors, and the reflex board is installed on the shoulders of the life jacket. Pay attention when buying.

The above is how to buy the answer to life jackets. Regarding these five major points, I hope everyone can understand it in detail and better apply it to actual life. At the same time, I hope that everyone can pay attention to personal safety and not easily get off the water.
