Answer: Maintenance items after 300~500h after the new machine is put into operation: oil change and oil filter change, air filter cleaning, leakage and looseness inspection, oil tank drainage, motor body cleaning, belt tightness inspection. Motor temperature rise, current, and host sound inspection.
Maintenance items after 2000h after the new machine is put into operation: leakage and looseness inspection, oil tank drainage, body cleaning, oil-gas separator pressure difference, radiator cleaning, manual inspection of safety valve (pull rod), belt tightness and transmission device inspection, motor temperature rise current, and host sound inspection.
Maintenance items every 6 months or 4000 hours: oil change and oil filter change, air filter cleaning, oil and gas separation core change (or pressure difference exceeds 0.08MPa), check for leaks and looseness, drain oil storage tank, motor body cleaning, oil and gas separation and pressure difference, radiator cleaning, manual inspection of safety valve (pull rod), motor and cooling fan bearing lubricant change, electrical insulation and contact condition inspection, safety protection device inspection, circulation system aging inspection, belt tightness and transmission device inspection, motor temperature rise, current, and host sound inspection.
Maintenance items every 12 months or 8000h: oil change and oil filter change, air filter cleaning, oil and gas separation core change (or pressure difference exceeds 0.08MPa), check for leaks and looseness, drain oil storage tank, clean motor, oil and gas separation and pressure difference, clean radiator, change lubricating oil for motor and cooling fan bearings, check electrical insulation and contact conditions, check safety protection devices, check aging of circulation system and control system, check safety valve and pressure gauge by national specified department for inspection or replacement, check or replace pressure controller, solenoid valve, minimum pressure valve, temperature controller, intake valve and transmission device, check electrical main switch, check motor temperature rise, current and host sound, and reliability of safety device.
The above maintenance items should be strictly implemented by users. The maintenance time requirements of air compressors of different brands are different. The most reasonable maintenance time is still determined by users according to the operating status of the air compressor.
