Do you know all this knowledge about the wearing parts of screw air compressor?

The air filter of an air compressor is composed of an air filter assembly and a filter element. The outside is connected to the air compressor’s intake valve through a joint and a threaded pipe, so as to filter the dust, particles and other impurities in the air. Different air compressor models can choose the air filter to be installed according to the size of the air intake.

Failure Appearance: The filter is clogged, and the clogged air filter will cause the air compressor to lose energy and waste electricity, and it is easy to be penetrated by dust. Excessive dust entering the inside of the air compressor will affect the life of the air compressor oil and cause the oil/air separator to block.

Troubleshooting:

• The filter element is the core component of the filter. It is made of special materials and is a vulnerable part that requires special maintenance.
• When the filter has been working for a long time, the filter element in it has blocked a certain amount of impurities, which will cause the pressure to increase and the flow to decrease. At this time, it needs to be replaced in time.

The filter paper in the equipment is also one of the key points. The filter paper in high-quality filter equipment usually uses superfine fiber paper filled with synthetic resin, which can effectively filter impurities and has a strong dirt storage capacity. The equipment also has great requirements for the strength of the filter paper. Due to the large air flow, the strength of the filter paper can resist strong airflow, ensuring the efficiency of filtration and prolonging the service life of the equipment. The pore size of the filter paper is about 10μm. Usually it should be removed and replaced every 2000 hours. A differential pressure control device is installed on the air filter. If the display panel shows that the air filter is clogged, it means that the air filter must be cleaned or replaced.

Two: Oil Filter

The oil filter is generally a paper filter. Its function is to remove impurities in the oil such as metal particles and oil degradation. The filtering accuracy is between 5μm-10μm, and it has a protective effect on the bearing and the rotor.

Failure Appearance: Oil filter failure.

Troubleshooting: Whether the oil filter should be replaced can be judged by its pressure difference indicator. If the pressure difference indicator light is on, it means that the oil filter is blocked and must be replaced. The oil and oil filter need to be replaced after the first 500 hours of operation of the new machine, and then replaced according to the pressure difference indicator light.

If the oil filter is not replaced due to a large pressure difference, it may result in insufficient oil intake, and the high temperature of the exhaust will trip and the lack of oil will affect the life of the bearing.
