螺桿空壓機進氣閥工作原理
    對于空壓機電磁閥的一個總的規(guī)律就是：電磁閥得電加載，失電卸載。有時候我們的設備有在卸載的情況下出現(xiàn)電流稍微有點大，22KW的卸載時電流有31A。初步懷疑進氣閥沒關嚴，因為在沒用氣的時候，機器卸載后，壓力還會慢慢上升，有時會高壓報警停機！而且在停機后，機器內(nèi)部還有一些殘余壓力無法卸放（在6公斤左右），導致再次啟動時，主機過載。
    當空壓機進氣閥屬于常開式進氣閥,壓縮機在沒有加載時電磁閥是打開的,壓縮機加載后電磁閥是關閉的.當電磁閥打開時,會有一路氣體去關閉進氣閥,但是不能完全關死,還要保留進氣空間,以維持壓縮機潤滑所需要的最小壓力,這個壓力一般在1.5bar;電磁閥關閉后,壓縮機會進入正常工作狀態(tài),直至到設定的工作壓力,這取決于用戶.該進氣閥有兩路管,一路放空;一路放掉閥中余氣,保證壓縮機正常加載。卸載時,電流過大,說明罐壓較高,進氣閥開度梢大,請調(diào)整放空螺釘,保證罐壓不會太高. 
    空壓機停機后,罐壓一般在60秒左右就可以完全排空,即壓力為0.而你的罐壓還有6bar,說明進氣閥放空管路存在問題:1.可能是管路直徑過細;2.組合閥孔口過小或是否雜物堵塞。
    卸載后,壓力會有輕微的來回升高,但這個只是平衡需要,而且時間很短.不會上升到高壓停機.高壓停機應該是空壓機電磁閥存在問題,請檢查它是否完好,是否可以正常工作.不論什么樣的進氣閥,都應當在卸載時維持罐壓在1.0~2.0BAR之間.過高對于空壓機的能量是很大的浪費。

Screw air compressor working principle of the intake valve

For air compressor mechanical and magnetic valve is a general rule: the solenoid valve electricity load, loss of electric discharge. Sometimes we have the equipment under the condition of the discharge current slightly big, 22 kw current 31 a when unloading. Preliminary doubt inlet valve didn"t close tightly, because at the time of no gas, machine after unloading, the pressure will rise slowly, and sometimes high pressure alarm stop! And after the outage, the machine internal residual stress and some can"t discharge (around 6 kg), lead to start again, host overload.

Sky compressor inlet valve belongs to often open inlet valve, compressor without loading electromagnetic valve is opened, the compressor after loading the solenoid valve is closed. When the solenoid valve opens, there will be gas all the way to close the inlet valve, but can"t completely shut up, and keep intake space, in order to maintain the compressor lubrication required minimum pressure, the pressure is in commonly 1.5 bar; Solenoid valve is turned off, the normal work of the compressor enters the state, until to set the working pressure, depending on the user. The inlet valve tube have two road, empty all the way; Residual air in drain valve all the way to ensure that the normal load compressor. When unloading, current is too large, tank pressure is higher, the intake valve opening tip is big, please adjust the vent screw, ensure that tank pressure does not too high.

Air compressor after downtime, tank pressure generally within 60 seconds can be completely emptying, the pressure of 0. And you the tank pressure of 6 bar, shows that inlet valve vent piping problems: (1) may be pipe diameter carefully; 2. The combination valve orifice is too small or if sundry jam.

After unloading, the pressure may have a slight rise, back and forth with this just need balance, but time is short. Don"t rise to high downtime. High downtime should be air compressor mechanical and magnetic valve there is a problem, please check if it is in good condition, whether can work normal. No matter what kind of intake valve, shall be maintained when unloading tank pressure is between 1.0 ~ 2.0 BAR. Too much for the air compressor is a great waste of energy.
