Maintenance Contents of Air Compressor

Due to the harsh working environment of the air compressor, its maintenance is particularly important when operating under high temperature and pressure for a long time. In order to prevent aging or wear of parts and components that may adversely affect the stability and performance of the air compressor, relevant workers are required to do a good job in daily maintenance of the air compressor, thereby reducing the incidence of air compressor failures and preventing major safety accidents. Air compressor operators should strictly follow the provisions of the relevant documents on air compressor maintenance and repair, promptly identify and solve problems, so as to ensure the normal operation of relevant departments of the enterprise and ensure the economic benefits of the enterprise.

（1） Daily maintenance of air compressor

The daily maintenance and service of the air compressor is crucial to ensure the normal operation of the air compressor, mainly including the following: First, relevant operators conduct comprehensive inspection and testing before equipment operation, which is the basic step to ensure the normal and stable operation of the air compressor. Efforts should be made to ensure that the daily maintenance and service work is in place and that the inspection is complete without omission, It is necessary to formulate detailed and comprehensive daily maintenance rules and regulations, establish a sound supervision mechanism, and strive to improve the skills and comprehensive quality of operators.

Before starting the air compressor, the operator should conduct a comprehensive inspection of the equipment, including checking whether the amount of lubricating oil in the oil pool and injector is sufficient; Check whether the protective device is secure and safe; Check whether the oil and gas pipelines are smooth; Check whether each operating component is flexible, etc. The key point of daily maintenance work should be to observe whether various instrument readings of the air compressor are normal under operating conditions, whether there are abnormal noises and parts heating conditions, and whether there are operating abnormalities in main components. Through various testing equipment and combined with practical experience, problems should be identified and resolved in a timely manner to ensure the normal operation of the air compressor. Operators must operate the equipment in strict accordance with operating procedures, keep records of the operating conditions of the machinery and equipment, and perform spot checks on the main components of the pneumatic molding machine.

（2） Regular maintenance of air compressor

Doing a good job in the daily maintenance of the air compressor is only the foundation of the air compressor maintenance work. On the basis of doing a good job in the daily maintenance and maintenance inspection, it is necessary to make a good plan for its regular maintenance and long-term maintenance. Formulate specific maintenance rules based on the equipment manual of the air compressor and in combination with the equipment usage status, mainly including cleaning and maintenance of the air filter, replacement and repair of various air valves of the air compressor, regular inspection and maintenance of the cylinder, and inspection and calibration of various instruments and meters. In order to ensure the normal and stable operation of the air compressor and extend the service life of the equipment, it is necessary to formulate a detailed and complete equipment maintenance plan, determine the monthly, three-month, and semi-annual inspection and maintenance content, so as to meet the working requirements for efficient and safe operation of the air compressor. Monthly maintenance content: Determine whether cleaning is necessary based on the contamination of the surface of the oil cooler, check whether the lubricating oil deteriorates and whether the connecting hose is aged or damaged, and check the connection of the oil circuit and circuit. Maintenance content every three months: add lubricating grease to clean the bearings of the main motor and fan motor, clean the cooler, condenser, oil filter, and air filter, and check whether various air valves and sensors are replaced. Half a year's maintenance content: Check the use of cooling fans, cylinders, safety valves, and oil-gas filter elements, focusing on the analysis of the overall operating condition of the air compressor, replacing relevant components, and eliminating potential safety hazards.

（3） Maintenance of main components of air compressor

The air compressor is mainly composed of relevant components such as the body, cylinder, piston, oil filter, gas cooler, air filter, etc. Some of these components are extremely prone to wear and aging, resulting in the inability of the air compressor to operate normally. Therefore, it is necessary to strengthen the maintenance and repair of key components related to the air compressor, so as to ensure the continuous and stable operation of the air compressor and reduce the failure rate, Reduce downtime and maintenance times. The air filter mainly filters dust and impurities in the air, and its working effect will affect the service life of the air compressor cylinder to a certain extent; The life of the piston ring is related to the gas temperature inside the cylinder, the quality of the air filter, and the moisture content in the air; The lubricating grease for each component can greatly improve the wear of the parts, thereby extending the service life of the device. Therefore, it is necessary to ensure that the amount of lubricating oil is sufficient; In order to ensure the stable operating temperature of the air compressor, it is necessary to ensure that the cooling effect of the cooler is good; As a key component that determines the quality of compressed gas in an air compressor, the oil gas separator must ensure its good filtration efficiency.
