空壓機安全閥頻繁起跳還噴油，到底是怎么了？

連續遇到客戶(hù)咨詢(xún)同樣一個(gè)問(wèn)題：空壓機安全閥起跳頻繁、還噴油，不知道問(wèn)題出在哪里？通過(guò)多年服務(wù)經(jīng)驗，總結出空壓機安全閥起跳故障的主要因素有以下五個(gè)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、安全閥失靈提前打開(kāi)

1、 The safety valve fails and opens ahead of time

空壓機安全閥起跳時(shí)需要核實(shí)下安全閥起跳時(shí)的壓力，如果機器還沒(méi)到卸載壓力安全閥就提前打開(kāi)，那么這個(gè)時(shí)候有必要關(guān)注機器面板或油分桶處壓力表的壓力值，就是安全閥的起跳壓力。

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.

處理建議：更換新的安全閥，螺桿空壓機安全閥最好由空壓機維修人員來(lái)更換，這樣既能保證客戶(hù)安全，又能保證螺桿式空壓機不被誤操作帶來(lái)一些損傷，影響使用壽命。

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、機器不卸載，一直加載超出安全閥起跳壓力

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

空壓機打氣加載到一定的壓力就會(huì )卸載，壓力不會(huì )一直往上升，如果機器面板上顯示到了卸載壓力機器還在繼續加載，那么這個(gè)時(shí)候壓力繼續往上，超過(guò)安全閥起跳壓力，安全閥起跳并伴有嘭的一聲巨響，油氣往外噴。

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.

處理建議：檢查機器加卸載的小活塞或者電磁閥，必要時(shí)更換新的。

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

三、出氣口出氣不通暢，導致氣流波動(dòng)異常

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

出氣口有異物導致機器出氣不通暢，出現這類(lèi)現象安全閥會(huì )間斷性起跳，有的時(shí)候隔幾個(gè)小時(shí)，有的時(shí)候隔幾天甚至更久。比如小壓力閥動(dòng)作不靈敏、機器出氣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.

處理建議：仔細檢查小壓力閥、出氣口疏水器內部有無(wú)破裂等情況來(lái)逐一確定。

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

四、其他情況

4、 Other information

比如少部分機型小壓力閥的結構設計比較特殊，在保養時(shí)把上面的控制管路安裝反了等。

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.
