How long can different thermal water tanks generally keep insulation?The principle and structure of the insulation water tank

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.

Making method steps

1,After selecting high -quality board, take the selected plate for precise cutting;

2,After the plate cutting is completed, the corner suppression is performed;

3,Modules with tailoring, corners, and molding molding are transported to the construction site for on -site stitching and production;

4,Whether the size and basic size of the water tank on the spot are consistent;

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.
