Failure type and cause analysis of air compressor

1.1 排气量不足

1.1 insufficient exhaust volume

排气量的不足最主要的表现是压力达不到终点压力，从故障现象看很可能是由于以下几种原因造成：

The most important performance of the exhaust volume is that the pressure can not reach the end point.

      

      

一是入口空气过滤器的故障，当过滤器中的积垢产生堵塞，就会使排气量减少；而吸气管过长，管径较小，造成吸气阻力增大时，就直接影响了排气量。

One is the failure of the inlet air filter. When the fouling in the filter is blocked, the volume of the exhaust will be reduced; and the suction pipe is too long and the pipe diameter is small. When the suction resistance increases, the exhaust volume is directly affected.

      

      

二是空压机转速过低会使排气量下降：空气压缩机的排气量是按规定的海拔高度、吸气温度、湿度设计的，如果在超过上述标准的高原上使用时，就会造成吸气压力降低，排气量也随之降低；传送皮带打滑一会降低空压机的转速，进而影响排气量降低。

The two is that the air compressor speed is too low will reduce the exhaust volume: air compressor exhaust volume is designed according to the altitude, air suction temperature, humidity, if it is used above the above standard plateau, the suction pressure will be reduced and the volume of exhaust will decrease; transmission belt slipping will reduce the speed of air compressor. Speed, and then affect the reduction of exhaust gas.
