1、自动增压泵的单向阀密封不好，造成水压回流到市政管网中，水压降低了增压泵自然要启动补压，可以通过将压力打到一定数值然后断电观察指针压力表，看压力是否不断下降，没有用水水压下降则说明单向阀漏水。
1. The one-way valve of the automatic booster pump is not well sealed, resulting in the backflow of water pressure into the municipal pipe network. When the water pressure is reduced, the booster pump naturally needs to start pressure supplement. You can turn off the power and observe the pointer pressure gauge to see whether the pressure continues to decline. If there is no water, the water pressure drops, it indicates that the one-way valve is leaking.
2、家用水管有地方漏水，这种情况虽然可能性少也不是不可能，有漏水就会造成泄压，压力低了通用会启动增压。
2. There is water leakage in the domestic water pipe. Although this situation is less likely, it is not impossible. If there is water leakage, it will cause pressure relief. When the pressure is low, GM will start pressurization.
3、压力感应开关有问题，造成反馈的压力时高时低，也会造成增压泵启动增压。如果排除了1、2项则一定是压力感应开关问题，联系厂家更换传感器。
3. There is a problem with the pressure sensing switch, causing the feedback pressure to be high and low, which will also cause the booster pump to start boosting. If items 1 and 2 are excluded, it must be the problem of pressure sensing switch. Contact the manufacturer to replace the sensor.
4、增压泵有个特性，当管道流量跟不上水泵的流量或超过水泵的流量时，增压效果也不明显。所以在选购水泵前要排查水压偏低的原因，不能盲目购买水泵。若要购买，建议咨询管道工或找经验丰富的商家做参谋。要商家参谋的好处是，万一水泵增压效果不理想可以理直气壮的要求商家调换或者退货。
4. Booster pump has a characteristic, when the pipeline flow can not keep up with the flow of the pump or exceed the flow of the pump, the booster effect is not obvious. Therefore, before purchasing the water pump, the reason for the low water pressure should be investigated, and the water pump should not be purchased blindly. If you want to buy, it is recommended to consult a plumber or find an experienced merchant as a consultant. The advantage of business advice is that in case the pressurization effect of the water pump is not ideal, you can justifiably ask the business to replace or return.
5、气液增压泵工作原理类似于压力增压器，对大径空气驱动活塞施加一个很低的压力，当此压力作用于一个小面积活塞上时，产生一个高压。通过一个二位五通气控换向阀，增压泵能够实现连续运行。
5. The working principle of gas-liquid booster pump is similar to that of pressure booster. It applies a very low pressure to the large diameter air driven piston. When this pressure acts on a small area piston, a high pressure is generated. Through a two position five ventilation control directional valve, the booster pump can realize continuous operation.
