Pot-type pressure-superposed water supply device with small-flow auxiliary pump for energy saving
The invention discloses a pot-type pressure-superposed water supply device with a small-flow auxiliary pump for energy saving. The pot-type pressure-superposed water supply device is mainly composed of a flow stabilization compensator, a non-negative-pressure controller, an air pressure water tank, the small-flow auxiliary pump, a solenoid valve, a main pump, a flow detecting device and a control cabinet. A second bypass pipe is arranged between a water distribution header pipe and a water outlet header pipe in the manner of bypassing a main pump, and a small-flow pipe is arranged at the position, behind a third check valve, of the second bypass pipe to be connected with the air pressure water tank; and the solenoid valve and a second pressure detecting meter are installed on the small-flow pipe, and a first bypass pipe is further arranged at the position, by passing the solenoid valve and the second pressure detecting meter, of the small-flow pipe. The pot-type pressure-superposed water supply device has the beneficial effects that the small-flow auxiliary pump and the air pressure water tank are arranged, so that the energy saving water supply effect can be better achieved when the flow is small; the pressure-superposed water supply energy-saving potential is further excavated, and the energy-saving flow range is enlarged; in addition, the using rate of the effective volume of the air pressure water tank can be greatly improved through the small-flow auxiliary pump, and the investment and the occupied land are better saved.
