A complete air compressor is composed of many parts. Of course, some important parts will appear. Once there is a problem in this part, the machine will not work. There are also some parts that are difficult to find, and they will not stop immediately, such as air inlet duct or rubber bending head. However, long-term use will cause great damage to the air compressor host and rear equipment.

空气品质不好，成为气动系统出现故障的主要因素，它会使气动系统的可靠性和使用寿命大大降低，由此造成的损失会大大超过气源处理装置的成本和维护费用，故正确选用气源处理系统及其元件是非常重要的。

Poor air quality has become the main factor for the failure of the pneumatic system. It will greatly reduce the reliability and service life of the pneumatic system, and the resulting loss will greatly exceed the cost and maintenance cost of the air source treatment device. Therefore, it is very important to correctly select the air source treatment system and its components.

从空压机输出的压缩空气中，含有大量的水分、油分和粉尘等污染物，一定适当这些污染物，以避免它们对气动系统的正常工作造成危害。

The compressed air output from the air compressor contains a lot of pollutants such as moisture, oil and dust. These pollutants must be properly removed to avoid harm to the normal operation of the pneumatic system.

变质油分的粘度加大，从液态逐渐固态化而形成焦油状物质。它会使橡胶及塑料材料变质和老化；积存在后冷却器、干燥器内的焦油状物质，会降低其工作效率；堵塞小孔，影响元件性能；造成气动元件内的相对运动件的动作不灵活；焦油状物质的水容液呈酸性，会使金属生锈、污染环境和产品。

The viscosity of the modified oil increases and gradually solidifies from the liquid to form tar like substances. It will cause deterioration and aging of rubber and plastic materials; Tar like substances accumulated in aftercooler and dryer will reduce their working efficiency; Block the small hole and affect the performance of the element; Causing inflexible action of relative moving parts in pneumatic components; The water containing liquid of tar like substances is acidic, which will rust the metal and pollute the environment and products.

水分会造成管道及金属零件腐蚀生锈，使弹簧失效或断裂；在寒冷地区以及在元件内的高速流动区，由于低温太低，水分会结冰，造成元件动作不好、管道冻结或冻裂；管道及元件内滞留的冷凝水，会导致流量不足、压力损失加大、甚造成阀的动作失灵；冷凝水混入润滑油中，会使润滑油变质；液态水会冲洗掉润滑脂，导致润滑不好。

Moisture will cause corrosion and rust of pipes and metal parts, resulting in failure or fracture of springs; In cold areas and high-speed flow areas in components, due to low temperature, water will freeze, resulting in poor component action, pipeline freezing or frost cracking; The condensate trapped in the pipeline and components will lead to insufficient flow, increased pressure loss, and even valve action failure; If the condensate is mixed into the lubricating oil, the lubricating oil will deteriorate; Liquid water will wash off the grease, resulting in poor lubrication.

锈屑及粉尘会使相对运动件磨损，造成元件动作不好，甚卡死；粉尘会加速过滤器滤芯的堵塞、加大流动助力；粉尘等会加速密封件损伤，导致漏气。

Rust chips and dust will wear the relative moving parts, resulting in poor action or even jamming of the components; Dust will accelerate the blockage of filter element and increase flow assistance; Dust will accelerate seal damage and lead to air leakage.
