The maintenance compressed air systems are often specified in the system documentation, provided by the manufacturer. 

In this artical Minh Phu would like to  introduce some rules of maintenance  according to general regulation.

- Check air filters and pneumatically handling equipment, condensate water discharge and contaminants properly regulated; Adjust the pneumatic lubricator (if used).
- Exxchange to the operator to know about the operation status of the system, does anything unusual happen?
- Check for the leakage in parts and air pipes; Note whether or not the air pipes are kinked or damaged by physical damage.
- Check the abrasion status, dirt in the signaling parts.
- Check the bushings in the cylinder and check the cylinder.

1.Maintenance plan:

Daily:

-Cheeck oil level in the lubricator of the compressed air (if available) and check the oil quantity.

Weekly:

- Check the signaling unit  .

- Check pressure gauge of  pressure regulator

- Check the operation of the lubrication unit.

Every 3 months: 

- Checking  the seals whether they are leaking or not. Tighten the  connections,If necessary,

- Replace air pipes connecting to moving units.

- Check the leakage of discharge  air outlet
