If you find that the booster pump does not stop working without water, it may be caused by the following reasons:
1. The shutdown pressure may be set too high. If the shutdown pressure is set too high, no matter there is no water, the booster pump cannot reach the set pressure and will not shut down naturally.
Solution: if there is a pointer pressure gauge, first look at the position indicated by the pointer pressure when the current does not stop, write down the pressure value, and then check the corresponding set stop pressure value (only for self setting). Pressure value), reduce the set shutdown pressure value appropriately, and then try again.
2. The check valve leaks. The function of one-way valve is to prevent the pressure backflow of pressurized water, resulting in pressure drop. If the one-way valve is not well sealed, resulting in water leakage, the set upper limit cannot be reached, and the pump will not stop.
Solution: first pressurize the booster pump to a certain value, write down the value, then turn off the power supply of the booster pump, and observe whether the pointer will fall. If it falls, it means water leakage. If there is no pressure gauge, you can only stop for a while, and then turn on the tap to see if the water pressure drops significantly.
3. Other water pipes are leaking. Water leakage at other water points in the pipe network will also cause the pressure to continue to drop and fail to reach the set shutdown pressure value.
Solution: This is unlikely, but it is still necessary to observe whether there is leakage.
4. The controller or sensor of the booster pump is broken. If the above three steps are still invalid, the controller or sensor of the booster pump may be broken.
Solution: this kind of specialty is relatively strong. Generally, it is not easy to test without the guidance of the manufacturer. There is a risk of electric shock.
In addition, when the pressure is balanced, the pump will stop automatically, and a single pneumatic unbalanced valve is used to realize the automatic reciprocating motion of the pump. The pneumatic part of the pump body is made of aluminum alloy. The parts in contact with liquid are made of carbon steel or stainless steel according to different media, and the full set of seals of the pump are imported high-quality products, so as to ensure the performance of the gas-liquid booster pump.
