When purchasing water-lubricated variable frequency air compressors, it is also necessary to understand the maintenance of traditional oil-filled air compressors. When you know the maintenance cost of the traditional air compressor and combine the "water lubricated variable frequency air compressor" produced by Shanghai granklin group, you can know how much difference there is in maintenance and whether it is more economical.
As the most widely used air source power supply equipment, screw air compressor has been widely used in various industries. For a user, it is a very important job to know which parts of screw air compressor need to be replaced frequently. If the maintenance of screw air compressor is not paid attention to, it will affect the operation of the machine and even cause equipment problems.

so, what parts of the screw air compressor need to be replaced frequently?
1. oil filter
after the new machine runs for 500 hours for the first time, the oil filter element should be replaced, and the oil filter element should be removed with a special wrench. It is better to add screw machine coolant before installing the new filter element. The filter element should be screwed back to the oil filter seat with both hands and tightened firmly. It is recommended to replace the new filter element every 1500-2000 hours, and it is best to replace the oil filter element at the same time when changing the coolant. The replacement cycle of parts should be shortened when used in harsh environments.
It is forbidden to use the oil filter element beyond the time limit. Otherwise, due to the serious blockage of the oil filter element, the pressure difference exceeds the bearing limit of the bypass valve, and the bypass valve opens automatically. Many dirt and particles will directly enter the screw main engine with random oil, causing serious consequences.
2. air intake air filter element
the air filter is a component that filters and eliminates air pollutants. The filtered clean air enters the screw rotor compression cavity for compression. Because the internal gap of the screw machine only allows particles within 15u to be filtered out. If the air filter element is blocked and damaged, many particles larger than 15u will enter the screw machine to circulate, which will not only greatly shorten the service life of the oil filter element and the oil and gas separation core, but also cause many particles to directly enter the bearing cavity, accelerate the bearing wear, increase the rotor gap, decrease the tightening efficiency, and even dry the rotor to death. The device of the air intake filter element is very simple.
1. Facing a flat surface, tap the two end faces of the filter element in turn to remove most of the heavy and dry dust.
2. If the filter element is found to be thinned, pinhole or damaged, it should be discarded immediately.
3. Use dry air less than 0.28Mpa to blow in the opposite direction to the inhaled air. The nozzle is at least 25mm away from the folded (meaning: folding part of the object) paper and blows up and down along its height direction.
