压缩机三滤保养的项目
Maintenance of three filters for compressors
1、更换机油过滤器；
1, replace the oil filter;
2、更换空气过滤器；
2, replace the air filter;
3、更换油气分离器；
3, replace the oil and gas separator;
4、更换空压机润滑油；
4, replace the air compressor lubricating oil;
二、具体操作方法（以下操作须在停机断电并保证机内无压力才可进行）
Two, the specific operation methods (the following operations must be shut down and the power is not allowed to be carried out within the machine).
1、更换空气过滤器
1. Replace air filters.
拆卸空气过滤器外罩尾部螺丝、取下外罩尾部，拆卸空气过滤器锁紧螺丝，取出空气过滤器，将新过滤器装入，按反步骤装回过滤器及外罩。
Remove the tail screw of the air filter cover, remove the tail of the cover, remove the locking screw of the air filter, remove the air filter, load the new filter, and install the filter and the cover in reverse steps.
2、更换油过滤器
2. Replace the oil filter.
用专用工具锁紧过滤器底部正向旋转拧开过滤器，用干净的布条清洁过滤器底坐并涂上少许机油，在新机油过滤器的密封圈上涂上少许机油，装上新过滤器，并用专用工具锁紧。
Use a special tool to lock the bottom of the filter and turn it forward. Use a clean cloth strip to clean the bottom of the filter and coat it with a little oil.
3、更换油气分离器
3. Replace oil and gas separator.
方法与更换油滤相同。
The method is the same as replacing the oil filter.
4、更换空压机润滑油
4. Replace air compressor lubricating oil.
油的温度在3060℃时粘度会降低并且不会烫手，同时也利排净机组的残油。所以在换油时如是冷油，先开机运行2—3分钟。换油时应确保机组无压力才可进行。先拆开油气分离桶注油螺母、用合适的容器准备装残油。打开桶部下面的排油阀，排油时时而用手正盘机头皮带轮以利将储在机头内的油也排出。
When the temperature of the oil is between 30 and 60 degrees, the viscosity will decrease and it will not be hot. So when changing the oil, if it is cold oil, start up for 2 to 3 minutes. When changing the oil, ensure that the unit is free from pressure. First dismantle the oil and gas separation barrel oil filler nut, and use the appropriate container to prepare the residual oil. Open the oil discharging valve under the barrel, and sometimes use the belt pulley on the head of the machine to discharge the oil stored in the nose.
待油彻底排完后，关闭排油阀。注入新润滑油，注油时时而用手反盘机头皮带轮以利将油吸入管道及机头。注油量在浸过油位镜后再注入2~3cm（此为经验值，实际油位需在开机并加载状态时观测），注好油后，装上注油螺母并锁紧，拆下进气阀，从机头进气口注入少量润滑油，油量在浸没转子的三分之二处即可，装上进气阀。清洁空压机各部件表面。
When the oil is completely drained, close the drain valve. Inject new lubricating oil and use hand reverse head pulley to inject oil into pipes and heads. Oil injection volume is 2~3 cm after immersion in the oil level mirror (this is the experience value, the actual oil level should be observed when the engine is on and loaded). After oil injection, the oil injection nut is installed and locked, the inlet valve is removed, a small amount of lubricant is injected into the inlet of the engine head, and the oil volume is two-thirds of the submerged rotor, and the inlet valve is installed. Clean the surface of each component of the air compressor.
