Air compressor, lubricating oil, action screw, air compressor lubricating oil system ① during the working process of lubricating oil system, lubricating oil is pressed into the oiler under the action of gas pressure in the oil-gas barrel. After the lubricating oil is added, the impurity particles are removed through the oil filter, and then divided into two routes. One route is sprayed into the compression chamber at the lower end of the machine body to compress air, and the other route is connected to both ends of the machine body to lubricate the bearing group and transmission gear, and then the lubricating oil of each part is discharged with the compressed gas in the compression chamber.

与油混合的压缩气体进入油气桶，分离一大部分的油，其余的含油雾气体再经过油细分离器，滤去剩余的油，经保压阀进入后部器，即回送使用的系统中。②润滑油系统的油路组件．油器油器与气体接触后，器的方式相同，有风冷与水冷二种方式。若环境状况不佳，则风冷式器的翅片易受灰尘覆盖而影响，排气温度会过高而致跳机。

The compressed gas mixed with oil enters the oil-gas drum to separate a large part of the oil. The remaining oil mist gas passes through the oil fine separator to filter the remaining oil, and enters the rear filter through the pressure retaining valve, that is, it is returned to the used system. ② The oil circuit components of the lubricating oil system. After the oil cooler contacts with the gas, the way of the oil cooler is the same, including air cooling and water cooling. If the environmental condition is poor, the fins of the air-cooled cooler are easily affected by dust coverage, and the exhaust temperature will be too high to trip.

因此，应定期用压缩气体将翅片表面的灰尘吹掉，若无法吹干净则必须以溶剂来清洗，务必保持器散热表面干净。管壳式器在堵塞时，必须用化学清洗浸泡，且以机械清洗的高压水将堵塞在换热管内的结垢，务必确保完全清洗干净。．油过滤器油过滤器是一种纸质的过滤器，其能是除去油中杂质如金属微粒、油杂质及油沉淀物等。

Therefore, the dust on the fin surface should be blown off regularly with compressed gas. If it cannot be blown clean, it must be cleaned with solvent. Be sure to keep the heat sink surface clean. When the shell and tube heat exchanger is blocked, it must be soaked with chemical cleaning, and the scale blocked in the heat exchange tube must be removed with mechanically cleaned high-pressure water. Make sure it is completely cleaned Oil filter oil filter is a paper filter, which can remove impurities in oil, such as metal particles, oil impurities and oil sediment.

过滤精度在～之间，对轴承及转子有完善的保护作用，是否应当更换油过滤器可由其压差指示和运转时间来判断，如果压差指示灯亮，表示油过滤器阻塞，必须更换。

The filtering accuracy is between ~, which has perfect protection for the bearing and rotor. Whether the oil filter should be replaced can be judged by its differential pressure indication and operation time. If the differential pressure indicator is on, it indicates that the oil filter is blocked and must be replaced.

新机一次运转之后即需更换油及油过滤器，尔后则依据压差指示灯或运转时间而定是否更换。若油过滤器压差大而没更换，可能导致进油量不足，造成排气温度过高联锁停车，同时因油量不足会影响到轴承寿命。

The oil and oil filter shall be replaced immediately after the new machine runs for one time, and then whether to replace it shall be determined according to the differential pressure indicator or operation time. If the pressure difference of the oil filter is large and it is not replaced, it may lead to insufficient oil inlet, high exhaust temperature and interlocking shutdown. At the same time, insufficient oil will affect the service life of the bearing.
