空压机阀频繁起跳还喷油，到底是怎么了？

连续遇到客户咨询同样一个问题：空压机阀起跳频繁、还喷油，不知道问题出在哪里？通过多年服务经验，总结出空压机阀起跳故障的主要因素有以下五个方面：

Continuous customer consultation encountered the same problem: air compressor safety valve frequently jump, but also fuel injection, do not know where the problem? Through many years of service experience, summed up the air compressor safety valve take-off failure of the main factors are the following five aspects:

一、阀失灵提前打开

1、 The safety valve fails and opens ahead of time

空压机阀起跳时需要核实下阀起跳时的压力，如果机器还没到卸载压力阀就提前打开，那么这个时候有必要关注机器面板或油分桶处压力表的压力值，就是阀的起跳压力。

When the safety valve of air compressor takes off, it is necessary to verify the pressure when the lower safety valve takes off. If the safety valve is opened in advance before the machine reaches the unloading pressure, it is necessary to pay attention to the pressure value of the pressure gauge at the machine panel or oil separator barrel, which is the take-off pressure of the safety valve.

处理建议：更换新的阀，螺杆空压机阀由空压机维修人员来更换，这样既能保证客户，又能保证螺杆式空压机不被误操作带来一些损伤，影响使用寿命。

Treatment suggestions: replace the new safety valve. The screw air compressor safety valve should be replaced by the air compressor maintenance personnel. This can not only ensure the safety of customers, but also ensure that the screw air compressor will not be misoperated to bring some damage and affect its service life.

二、机器不卸载，一直加载超出阀起跳压力

2、 The machine does not unload, but always loads beyond the safety valve's take-off pressure

空压机打气加载到一定的压力就会卸载，压力不会一直往上升，如果机器面板上显示到了卸载压力机器还在继续加载，那么这个时候压力继续往上，超过阀起跳压力，阀起跳并伴有嘭的一声巨响，油气往外喷。

When the air compressor is inflated and loaded to a certain pressure, it will unload, and the pressure will not rise all the time. If the unloading pressure is displayed on the machine panel, the machine will continue to load, then the pressure will continue to rise at this time, exceeding the safety valve's jumping pressure, the safety valve will jump with a loud bang, and the oil and gas will spray out.

处理建议：检查机器加卸载的小活塞或者电磁阀，必要时更换新的。

Treatment suggestion: check the small piston or solenoid valve of the machine, and replace it if necessary.

三、出气口出气不通畅，导致气流波动异常

3、 The air outlet is not smooth, resulting in abnormal airflow fluctuation

出气口有异物导致机器出气不通畅，出现这类现象阀会间断性起跳，有的时候隔几个小时，有的时候隔几天甚更久。比如小压力阀动作不灵敏、机器出气口管道有偶然性堵塞等因素。

There are foreign matters in the air outlet, which lead to the unobstructed air outlet of the machine. In this case, the safety valve will jump intermittently, sometimes every few hours, sometimes every few days or even longer. For example, the small pressure valve action is not sensitive, the machine outlet pipeline has accidental blockage and other factors.

处理建议：仔细检查小压力阀、出气口疏水器内部有无破裂等情况来逐一确定。

Treatment suggestions: carefully check the small pressure valve and outlet steam trap for internal fracture to determine one by one.

四、其他情况

4、 Other information

比如少部分机型小压力阀的结构设计比较特殊，在保养时把上面的控制管路安装反了等。

For example, the structure design of small pressure valve of a few models is special, and the control pipeline above is installed reversely during maintenance.
