空压机故障类型及原因分析：
Analysis of the types and causes of air compressor faults:
1. 排气量不足
1. Insufficient Engine displacement
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 main manifestation of insufficient Engine displacement is that the pressure cannot reach the terminal pressure. From the fault phenomenon, it is likely to be caused by the following reasons:
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 dirt in the filter is blocked, the Engine displacement will be reduced; The suction pipe is too long and the pipe diameter is small, which will directly affect the Engine displacement when the suction resistance increases.
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 second is that the low speed of the air compressor will reduce the Engine displacement: the Engine displacement of the air compressor is designed according to the specified altitude, suction temperature and humidity. If it is used on the plateau beyond the above standards, the suction pressure will be reduced, and the Engine displacement will also be reduced; When the conveyor belt slips, the rotation speed of the air compressor will be reduced, thus affecting the reduction of Engine displacement.
三是由于零件磨损导致空压机各配合间隙的变化而引起的：气缸、活塞、活塞环磨损严重、超差，造成相关间隙增大，泄漏量增大，严重的话就影响了排气量。
The third is caused by the change of the fitting clearance of the air compressor caused by the wear of parts: the cylinder, piston and piston ring are severely worn and out of tolerance, resulting in the increase of the relevant clearance and the increase of the leakage. If it is serious, it will affect the Engine displacement.
四是空压机系统严重漏气，主要是由于填料函不严密从而产生漏气使气量降低，究其原因：首先，是填料函本身制造时不合要求；其次，可能是在安装时，活塞杆与填料函中心没有对好，产生磨损、拉伤等造成的漏气。
The fourth is severe air leakage in the air compressor system, mainly due to the loose packing box, which leads to a decrease in air volume. The reasons for this are: firstly, the packing box itself was not manufactured to meet the requirements; Secondly, it may be due to the misalignment between the piston rod and the center of the stuffing box during installation, resulting in air leakage caused by wear, strain, etc.
五是空压机压力阀的故障对排州苗木 保定通风管道 丝网立柱模具 尼龙输送带 保定空压机 高碑店养老院气量的影响，主要是指吸、排气阀的阀座与阀片间落入金属碎片或其它杂物，造成关闭不严，形成漏气。
Fifthly, the impact of the failure of the pressure valve of the air compressor on the Engine displacement mainly refers to the metal debris or other sundries falling between the valve seat and the valve plate of the suction and exhaust valves, resulting in untight closing and air leakage.
此外，气阀弹簧力与气体力匹配的不好也会影响排气量，弹力过强则使阀片开启迟缓，弹力太弱则阀片关闭不及时，这样不但影响了排气量，严重的话会影响到功率的增加，甚至影响气阀阀片、弹簧的使用寿命。
In addition, the poor matching between the air valve spring force and the air force will also affect the Engine displacement. If the spring force is too strong, the valve plate will open slowly. If the spring force is too weak, the valve plate will not close in time. This will not only affect the Engine displacement, but also affect the increase of power if it is serious, and even affect the service life of the valve plate and spring
