Background technology
Can negative interaction be produced after general supply equipment directly accesses tap water pipe network at present, because the flow of water pump is usually greater than running water pipe flow of inlet water, thus cause ductwork pressure to decline, affect periphery user water.In order to solve the irrationality of this water supply scheme, so traditional way of supplying water needs to build water source water tank and attic tank in the import department of water pump, there are following three problems in this traditional water supply scheme:
The first, all easily there is pollution problem in water pump water source water tank and attic tank, because the design in pond all exists overfall, the water tank of life also must periodic cleaning for avoiding water quality to degenerate, and thus causes the waste of drinking water.
The second, the building cost of attic tank is higher, and along with the development in city, attic tank is also difficult to see.
3rd, the tap water in city planting ductwork first will be put into water source water tank and then be extracted into attic tank with water pump, and like this, the pressure energy of tap water has just been wasted.
People have developed the secondary water supply system with steady flow compensation function for this reason, in secondary water supply system design process, when the water yield of city planting ductwork, hydraulic pressure can not meet the water yield, the hydraulic demand of user's pipe network, all needing, secondary pressurized equipment is set a water is promoted thus meets the needs of user's water.
At present; second pressure water supply equipment main on market is non-negative pressure water-supply installation; can match according to the concrete supply and demand condition of project; usually steady flow compensation tank can be configured with; steady flow compensation tank is equipped with vacuum eliminating device; but current secondary water-supply equipment or system are when utilizing cistern water supply, the pressure of the water that water tank flows out does not reach instructions for use, can not effectively control the hydraulic pressure entering steady flow compensation tank in real time.
