  Do you know the air inlet valve of air compressor? As an important part of air compressor, its function is very important. Let's learn more about it. The air inlet valve of the air compressor can also be said to be the air inlet control combination valve, which has the functions of air inlet control, loading and unloading control, volume regulation control, unloading, preventing unloading or shutdown, etc. Today, let's understand the working principle of the intake valve of screw air compressor and the reason why the intake valve can't be opened and the solutions!
  螺杆www.878365.com进气阀工作原理
  Working principle of intake valve of screw air compressor
  对于螺杆www.878365.com进气阀的一个总的规律就是:进气阀得电加载,失电卸载。
  For screw air compressor intake valve a general rule is: intake valve power load, power off unloading.
  有时候我们的设备有在卸载的情况下出现电流稍微有点大,22KW的卸载时电流有31A。初步怀疑进气阀没关严,因为在没用气的时候,机器卸载后,压力还会慢慢上升,有时会高压报警停机!而且在停机后,机器内部还有一些残余压力无法卸放(在6公斤左右),导致再次启动时,主机过载。
  Sometimes the current of our equipment is a little larger when it is unloaded. The current of 22KW is 31a when it is unloaded. It is preliminarily suspected that the intake valve is not closed tightly, because when the machine is unloaded, the pressure will rise slowly, and sometimes the high pressure alarm will stop! Moreover, after the shutdown, there are still some residual pressures in the machine that can not be discharged (about 6kg), resulting in the overload of the main engine when the machine is started again.
  当螺杆www.878365.com进气阀属于常开式进气阀,螺杆www.878365.com在没有加载时电磁阀是打开的,压缩机加载后电磁阀是关闭的。当电磁阀打开时,会有一路气体去关闭进气阀,但是不能完全关死,还要保留进气空间,以维持压缩机润滑所需要的最小压力,这个压力一般在1.5bar;电磁阀关闭后,压缩机会进入正常工作状态,直至到设定的工作压力,这取决于用户。
  When the screw air compressor inlet valve belongs to the normally open inlet valve, the solenoid valve is open when the screw air compressor is not loaded, and the solenoid valve is closed after the compressor is loaded. When the solenoid valve is opened, there will be a path of gas to close the intake valve, but it cannot be completely closed, and the intake space should be reserved to maintain the minimum pressure required for compressor lubrication, which is generally 1.5bar; after the solenoid valve is closed, the compressor will enter the normal working state until it reaches the set working pressure, which depends on the user.
  该进气阀有两路管,一路放空;一路放掉阀中余气,保证压缩机正常加载。卸载时,电流过大,说明罐压较高,进气阀开度梢大,请调整放空螺钉,保证罐压不会太高。
  The intake valve has two pipes, one for venting, the other for discharging the residual gas in the valve to ensure the normal loading of the compressor. When unloading, the current is too high, which means that the tank pressure is high and the opening tip of air inlet valve is large. Please adjust the vent screw to ensure that the tank pressure is not too high.
  螺杆www.878365.com停机后,罐压一般在60秒左右就可以完全排空,即压力为0,而你的罐压还有6bar,说明进气阀放空管路存在问题:
  After the screw air compressor is shut down, the tank pressure can be completely drained in about 60 seconds, i.e. the pressure is 0, and your tank pressure still has 6 bar, indicating that there is a problem in the vent pipeline of the intake valve:
  可能是管路直径过细;
  The pipeline diameter may be too thin;
  组合阀孔口过小或是否杂物堵塞。
  Whether the orifice of combination valve is too small or blocked by sundries.
  卸载后,压力会有轻微的来回升高,但这个只是平衡需要,而且时间很短。不会上升到高压停机,高压停机应该是www.878365.com电磁阀存在问题,请检查它是否完好,是否可以正常工作.不论什么样的进气阀,都应当在卸载时维持罐压在1.0~2.0BAR之间。过高对于螺杆www.878365.com的能量是很大的浪费。
  After unloading, the pressure will rise back and forth slightly, but this is only needed for balance, and the time is very short. It will not rise to high pressure shutdown. The high pressure shutdown should be caused by the problem of air compressor solenoid valve. Please check whether it is in good condition and can work normally. No matter what kind of inlet valve, the tank pressure should be kept between 1.0 and 2.0bar during unloading. Too high for screw air compressor energy is a great waste.
  螺杆www.878365.com进气阀打不开的原因与解决方案
  The reason and solution of screw air compressor's intake valve can't be opened
  螺杆www.878365.com的进气阀是控制储气罐内空气压力的组件,常用的进气阀有旋转碟片结构和往复阀板机构,利用碟片或阀板开启或关闭进气口,控制进入机头的气流。
  The air inlet valve of screw air compressor is a component to control the air pressure in the air storage tank. The commonly used air inlet valve has a rotating disc structure and a reciprocating valve plate mechanism. The disc or valve plate is used to open or close the air inlet to control the air flow into the head.
  有两种控制方式:一种是开关,当储气罐压力达到高限设定值,关闭进气口,当压力降到低限设定值,重新打开进气口。另一种是,当储气罐达到一定压力时,旋转碟片在比例阀的控制下微闭进气口,当储气罐压力进一步增大时,进气口进一步缩小,当储气罐压力略有减少时,进气口将有所加大,使压力稳定在一定范围。当压力未达到容调压力,进气阀碟片全开,进气口完全打开。
  There are two control modes: one is switch. When the pressure of the air tank reaches the set value of high limit, close the air inlet, and when the pressure drops to the set value of low limit, reopen the air inlet. The other is that when the air tank reaches a certain pressure, the rotating disc will close the air inlet slightly under the control of the proportional valve. When the pressure of the air tank increases further, the air inlet will be further reduced. When the pressure of the air tank decreases slightly, the air inlet will be increased to stabilize the pressure in a certain range. When the pressure does not reach the regulating pressure, the disc of the intake valve is fully open and the air inlet is fully open.
  而在运转的情况下,螺杆www.878365.com的进气阀出现关闭会有哪些原因呢,解决的办法有哪些呢?我们来简单的探讨一下吧!
  And in the case of operation, screw air compressor intake valve closed will have what reasons, solutions? Let's discuss it briefly!
  1、控制管道中水份过多,每天保养控制管道。
  1. The water in the control pipeline is too much, and the control pipeline shall be maintained every day.
  2、进气阀工作出错;检查气缸,阀套等部件,如必要则更换。
  2. The intake valve works in error; check the cylinder, valve sleeve and other components, and replace them if necessary.
  3、空气进气阀卡死;检查进气阀,阀套,或轴,如必要则更换。
  3. The air intake valve is stuck; check the intake valve, valve sleeve or shaft, and replace if necessary.
  4、进气阀弹簧断裂;更换弹簧
  4. Intake valve spring is broken; replace the spring
  5、电磁阀故障;按需要修理或更换,更换前应检查接线情况。
  5. The solenoid valve is faulty; repair or replace it as required, and check the wiring condition before replacement.
  6、往复阀损坏;维修或更换。
  6. The reciprocating valve is damaged; repair or replace.
  7、电磁阀电线接头松动;检查并拧紧电线端子。
  7. The wire connector of solenoid valve is loose; check and tighten the wire terminal.
  这些都会引起螺杆www.878365.com进气阀出现故障,在生产运作的时候应该谨慎处理。 进气阀一般为常闭阀,防止启动时大量气体进入机头,加大电机启动电流。
  These will cause screw air compressor intake valve failure, in the production operation should be handled with care. The air inlet valve is normally closed to prevent a large amount of gas from entering the machine head and increase the starting current of the motor.
  螺杆www.878365.com进气阀上有一个进气旁通阀,用来防止机器启动和空载时,机头内形成高度真空,影响润滑油的雾化。
  There is an intake bypass valve on the intake valve of screw air compressor, which is used to prevent the formation of a high vacuum in the head when the machine is started and unloaded, which affects the atomization of lubricating oil.
