A kind of box secondary water-supply steady flow compensation system that laminates
Technical field
The utility model belongs to supply equipment technical field, is specifically related to a kind of box secondary water-supply steady flow compensation system that laminates.
Background technology
At present general supply equipment can produce negative interaction after directly accessing tap water pipe network, because the flow of water pump is usually greater than running water pipe flow of inlet water, thereby causes ductwork pressure to decline, and affects periphery user water.In order to solve the irrationality of this water supply scheme, so traditional way of supplying water need to be built in the import department of water pump water source water tank and attic tank, there are three problems in this traditional water supply scheme, 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 use is for avoiding the water quality necessary periodic cleaning that also degenerates, thereby caused 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.The 3rd, the tap water in city planting ductwork will first 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, the water yield, hydraulic pressure that hydraulic pressure can not meet user's pipe network require, thereby all need to arrange secondary pressurized equipment, a water is promoted to the needs that meet user's water.
At present, on market, main second pressure water supply equipment is non-negative pressure water-supply installation, can match according to the concrete supply and demand condition of project, yet in actual application, above equipment still exists more problem and shortage, makes user's pipe network job insecurity.
