What do I need to change for the first maintenance of the air compressor?

The first maintenance of the air compressor usually requires the replacement or inspection of the following components and substances:

air filter: The air filter is located at the inlet of the air compressor and is used to filter the inlet air. After long-term operation, the filter material in the filter will gradually be blocked by pollution, so it needs to be cleaned or replaced. The replacement cycle can be judged according to the change of pressure difference, such as the pressure difference reaches 0.1MPa, which needs to be replaced.

Lubricating oil: The lubricating oil in the air compressor needs to be checked regularly and replaced according to the specified replacement cycle (such as 3000 hours). The quality of the oil directly affects the wear and failure rate of the air compressor.

Oil filter: The oil filter is used to filter impurities and metal particles in the lubricating oil and keep the oil clean. The replacement time of the oil filter can be determined according to the differential pressure. When the differential pressure is higher than 0.05MPa, replacement is recommended.

Intake valve: The intake valve directly contacts the intake air and will gradually wear out during operation. When it is found that the valve cannot be completely closed, or the pressure control is unstable, it is necessary to disassemble the valve for inspection or replacement.

In addition, the following items need to be checked:

discharge of oil storage drum: remove the dirt and water in the oil storage drum.

Body cleaning: Remove dust and dirt from the outside of the air compressor.

Radiator cleaning: remove the dust and dirt on the radiator to maintain a good heat dissipation effect.

Motor, cooling fan bearing lubricating oil: the motor and cooling fan bearings are lubricated to reduce wear and friction.

Electrical insulation and contact condition inspection: check the insulation performance and contact condition of the electrical system to ensure safety and reliability.

Check the temperature rise, current and host sound of the motor: check the temperature rise, current and host sound of the motor to judge whether the running state of the air compressor is normal.

It should be noted that the specific maintenance items and cycles may vary depending on the brand, model and use environment of the air compressor. Therefore, when performing the first maintenance, it is best to refer to the instruction manual of the air compressor or consult the after-sales service personnel to ensure the accuracy and effectiveness of the maintenance.
