增压泵一直嗡嗡响是怎么回事？其实这是很多廉价增压泵的一个通病，造成这种现象的主要原因可能有以下几点，气液增压泵厂家为您解说。

Why does the booster pump keep buzzing? In fact, this is a common problem of many cheap booster pumps. The main reasons for this phenomenon may be the following. The manufacturer of the gas-liquid booster pump will explain it to you.

1、压力控制系统有问题。水泵一工作就达到了控制的压力，水泵就不工作。是压力控制系统有问题。水泵一停机，压力又没有了。

1. There is a problem with the pressure control system. As soon as the water pump reaches the control pressure, the water pump will not work. There is a problem with the pressure control system. As soon as the water pump stops, the pressure disappears again.

2、止回阀漏水。止回阀本身是只能进不能出的，如果用了质量不过关的止回阀，当泵腔内水压增大时，已经被增压的水就会回渗到泵的进水端造成泵腔内部压力降低，传感器检测到水压降低后就会重新启动增压泵进行补压。

2. The check valve leaks. The check valve itself can only enter but not exit. If a check valve with poor quality is used, when the water pressure in the pump chamber increases, the pressurized water will seep back to the water inlet end of the pump, causing the pressure in the pump chamber to decrease. After the sensor detects that the water pressure decreases, it will restart the booster pump to supplement the pressure.

由于泵出水方向没有任何用水，很快压力重新补充上来，增压泵马上又休眠待机，往复循环就造成这种一响一停的现象。解决方法是重新更换质量过关的单向止回阀即可，其实绝大部分造成一响一停的原因就是止回阀造成的。

Since there is no water in the outlet direction of the pump, the pressure will be replenished soon, and the booster pump will sleep and stand by immediately. The reciprocating cycle will cause this phenomenon of "one ring and one stop". The solution is to replace the qualified one-way check valve. In fact, most of the reasons for "one click and one stop" are caused by the check valve.

3、泵出水管有地方漏水。出水管方向漏水导致一响一停也和止回阀漏水一响一停的原理是一样的，都是因为泵腔内水压降低导致水泵重新启动补压造成的，由于出水方向出水量很少，导致短时间压力上升到设定压力值而使增压泵停机保压。压力达到后因为漏水又会造成水压下降，增压泵又重新补压，往复循环就会造成一响一停的现象。

3. The outlet pipe of the pump leaks. The principle of "one click and one stop" caused by water leakage in the direction of the outlet pipe is the same as that of the check valve. Both are caused by the restart of the pump for pressure make-up due to the reduction of the water pressure in the pump chamber. Since there is little water output in the outlet direction, the pressure rises to the set value in a short time and the booster pump stops to maintain the pressure. After the pressure is reached, the water pressure will drop again due to water leakage, and the booster pump will supplement the pressure again. The reciprocating circulation will cause the phenomenon of one sound and one stop.

4、传感器故障。当压力反馈不准确后，也会造成这种现象，原理其实都是一样，当反馈了错误的低压力之后增压泵同样会补压，往复循环。

4. The sensor is faulty. When the pressure feedback is inaccurate, it will also cause this phenomenon. The principle is the same. When the wrong low pressure is fed back, the booster pump will also supplement the pressure and cycle back and forth.

5、用水频次太大。如果增压泵是压差控制的，当频繁有用水时，也会造成一启一停的现象发生。其原因也是和出水管漏水是一样的，而且这种情况可能一起一停会更频繁，特别是没有气压罐稳压的尤为严重。

5. The frequency of water use is too high. If the booster pump is controlled by differential pressure, the phenomenon of one start and one stop will also occur when water is frequently used. The reason is the same as the water leakage of the outlet pipe, and this situation may be more frequent when the pipes are stopped together, especially when there is no pressure tank to stabilize the pressure.

如果要杜绝这种情况，建议将压差式控制器改为变频器控制，或者直接更换全新的变频增压泵可以解决用水时一响一停的现象。关注我们//keonnected.com，了解更多！

If this situation is to be eliminated, it is recommended to change the differential pressure controller to frequency converter control, or directly replace a new variable frequency booster pump to solve the problem of "one sound and one stop" when using water.
