气液增压泵在平常频繁使用中，或者会出现气液增压泵预压复位慢的情况，其实这并不是什么大问题，经过排查找到原因后，一般用户都能自行解决。下面就向大家介绍下造成气液增压泵预压复位慢的原因及解决方法。

The gas-liquid booster pump is frequently used, or it may have a slow pre pressure reset. In fact, this is not a major problem. After troubleshooting, the general user can solve it by himself. Next, we will introduce the reasons and solutions for the slow pre pressure reset of the gas-liquid booster pump.

1、模具的重量，是否超出气液增压泵回程拉力范围。

1. Whether the weight of the mold exceeds the return pull range of the gas-liquid booster pump.

如果模具的重量超出气液增压泵回程拉力范围，就会造成气液增压泵预压复位慢甚至无法复位，所以在购买气液增压泵之前一定要准确告知生产厂家关于模具的重量，以免造成气液增压泵预压复位慢的情况。

If the weight of the mold exceeds the return pull range of the gas-liquid booster pump, it will cause the gas-liquid booster pump to reset slowly or even fail to reset. Therefore, before purchasing the gas-liquid booster pump, the manufacturer must be accurately informed about the weight of the mold to avoid the slow reset of the gas-liquid booster pump.

2、气源压力不足。

2. Insufficient air supply pressure.

也就是压缩空气的压力没有达到规定要求，再加上导向杆和模具的重量，导致气液增压泵预压复位慢。气液增压泵气源压力范围为4~7kg/cm2,标准值为6kg/cm2。

That is to say, the pressure of the compressed air does not meet the specified requirements, and the weight of the guide rod and the mold leads to the slow reset of the pre pressure of the gas-liquid booster pump. The air source pressure range of gas-liquid booster pump is 4~7kg/cm2, and the standard value is 6kg/cm2.

3、气体流量不足。

3. Insufficient gas flow.

先检查气液增压泵的进气口是否安装了节流阀，并检查气管长度、管径是否对气压造成影响。

First, check whether the throttle valve is installed at the air inlet of the gas-liquid booster pump, and check whether the length and diameter of the air pipe affect the air pressure.

4、气液增压泵内漏。

4. Internal leakage of gas-liquid booster pump.

这种情况检测比较困难，如检查以上没有出现问题，建议联系生产厂家。

This condition is difficult to detect. If there is no problem in the above inspection, it is recommended to contact the manufacturer.

建议大家在选购气液增压泵之前，一定要先确定好气液增压泵型号，以及回程拉力，以免因型号及回程拉力不对造成气液增压泵预压复位慢。不知道型号的可以联系厂家帮忙选型。很多相关内容就来我们网站//keonnected.com进行咨询吧！

It is suggested that before purchasing the gas-liquid booster pump, you must first determine the model of the pump and its return pull, so as to avoid slow resetting of the pump due to incorrect model and return pull. If you don't know the model, you can contact the manufacturer to help you select the model. A lot of relevant content will come to our website //keonnected.com Consult!
