Maintenance and maintenance of screw air compressor
Correct maintenance and maintenance play a vital role in the service life and operational reliability of screw air compressors.
1. Maintenance and maintenance of intake air filter element.
The air filter is a component that filters air dust and dirt, and the filtered clean air enters the compression chamber of the screw rotor for compression. The internal clearance of the screw air compressor only allows particles within 15u to filter out. If the air filter element is blocked and damaged, a large amount of 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 fine separation element, but also cause a large number of particles to directly enter the bearing cavity, accelerating bearing wear and increasing the rotor gap. The compression efficiency is reduced, and even the rotor is boring and seized.
The air filter element should be replaced every 1000-1500 hours under normal conditions, and the use of the environment is particularly harsh, such as mines, ceramic factories, cotton spinning mills, etc., it is recommended to replace the air filter element every 500 hours.
2. Replacement of oil filter.
The oil element should be replaced after 500 hours of operation of the new machine for the first time, and the oil filter element should be removed with a special wrench. It is better to add screw oil before installing the new filter element. Screw the filter element back to the oil filter seat with both hands and tighten it firmly.
It is recommended to replace the new filter element every 1500-2000 hours. It is best to change the oil filter element at the same time when changing the oil. When the environment is bad, the replacement cycle should be shortened.
3. Maintenance and replacement of oil fine separator.
The oil fine separator is a component that separates the screw lubricating oil from the compressed air. Under normal operation, the service life of the oil fine separator is about 3000 hours, but the quality of the lubricating oil and the filtering accuracy of the air have a huge impact on its life. It can be seen that the maintenance and replacement cycle of the air filter element must be shortened in the harsh environment, and even the installation of a pre-air filter is considered.
