Closed Expansion Tank
Also, known as a diaphragm tank, water supply pressure tank, water supply system accumulator device, etc. is a pressure vessel with a bladder-type rubber membrane inside the tank, used in water supply systems.
Protect the water pump from frequent opening, thereby prolonging the service life of the pump;
The water hammer phenomenon occurs in the system, and effective buffering is carried out;
When the power is off, make-up water is supplied through the expansion tank to stabilize the system pressure.
Specification
Provenance of the design: It adopts the same integral molding process as the fiber-reinforced materials of ultra-high-pressure containers such as storage tanks and LPG cylinders.
Benefiting from the hydrophobicity of the inner lining material of the tank, which meets the standard of direct drinking water, it uses a structure designed to pre-fill the pressure in the bladder and directly fill the tank with water.
Advantage: replace stainless steel, direct drinking water, corrosion resistance.
Although the surface of carbon steel and stainless steel tanks has been painted and polished, the inside of the tank has not been treated in any way. In the humid environment of water vapor, there is a risk of corrosion causing the tank to leak; The tank body of IWM is a one-piece structure without any welding points that damage the tank body. The inner lining of the tank is PE which meets the standard for direct drinking water and will not rust.Usually, the rubber diaphragm of the tank manufacturer is purchased from outside, and it is difficult to control the quality of the rubber and the rationality of the size fit; the water is always soaked in the rubber membranes, and the water quality deteriorates, which increases the risk and cost of water safety; IWM tank lining PE is hydrophobic, has no effect on water quality, meets the standard of direct drinking water, and the rubber membranes are designed and produced by IWM itself. It is a new rubber material without any recycled rubber, which guarantees maximum size matching and Water Safety.The water-filled structure of the rubber membranes needs to be disassembled at the flange at the bottom of the tank when the rubber membrane is replaced. However, under normal circumstances, the tank body is fixedly installed on the ground, and it is very inconvenient to disassemble and assemble it; Using the IWM expansion tank only needs to disassemble and replace the rubber membranes directly on the top, which is very convenient for construction personnel to operate.
In a humid and corrosive environment, the service life of traditional carbon steel and stainless steel materials will be greatly reduced and shortened; The advantage of IWM is that the tank body and tank feet are made of non-metallic materials, which can be used in corrosive environments.
