How to maintain oil-free air compressor

2026-04-10Views:

how is the oil-free air compressor maintained in daily life?

The core of the oil-free air compressor is the outstanding two-stage compression host. The rotor is finished by twenty processes to achieve accuracy and durability of the rotor line type. The interior is equipped with high-quality bearings and precision gears to ensure the coaxiality of the rotor and make the rotor match accurately, thus maintaining long-term, efficient and reliable operation.

The working principle of the whole machine:

air enters the compressor from the intake pipe. The rotation of the motor causes the piston to move back and forth, compressing the air, so that the pressure gas enters the air storage tank through the air outlet opening the one-way valve through the high-pressure hose. The pointer display of the pressure gauge rises to 8BAR, which is greater than 8BAR. The pressure switch automatically closes and the motor stops working. At the same time, the solenoid valve reduces the air pressure in the compressor head to 0, the gas is exhausted through the filter pressure regulating valve and the exhaust switch. When the air pressure in the air storage tank drops to 5kg, the pressure switch is automatically turned on and the compressor starts to work again.

Maintenance of main components of oil-free air compressor:

1, according to the above table maintenance and replacement of each component must be determined: the pressure in the oil-free air compressor system has been released, and other pressure sources have been separated, the main circuit on the switch has been disconnected, and have not closed the safety identification;

2. The replacement time of compressor cooling lubricating oil depends on the use environment, humidity, dust and whether there is acid and alkaline gas in the air. Newly purchased oil-free silent air compressor shall be replaced with new oil for the first 500 hours of operation, and then replaced every 4000 hours according to the normal oil change cycle. Machines with annual operation less than 4000 hours shall be replaced once a year;

3, the oil filter in the first boot operation 300-500 hours must be replaced, the second time in the use of 2000 hours of replacement, after the normal time every 2000 hours to replace;

4, maintenance and replacement of air filter or intake valve remember to prevent any debris into the compressor host cavity. When operating, the entrance of the host is closed. After the operation is completed, rotate several circles by hand according to the rotation direction of the host to make sure that there is no obstacle before starting up;

5. Check the tightness of the belt every 2000 hours or so in the machine. If the belt is loose, adjust it until the belt is tight. In order to protect the belt, it is necessary to prevent the belt from being scrapped due to oil pollution during the whole process;

each time the oil is changed, the oil filter must be replaced at the same time;

7. Replace parts with original company parts as far as possible, otherwise the supplier will not be responsible for matching problems.
