Sollant Air Compressor: 5 Daily Maintenance Guidelines You Must Know

Sollant Screw air compressors play a crucial role in industrial applications, and maintaining their efficient operation is essential. Below is a daily maintenance guide for screw air compressors, covering the replacement and maintenance of air filter elements, oil filter elements, screw air compressor oil, oil-gas separation cores, and cooler maintenance.

1.Maintenance and Maintenance of Air Filter Elements

It is best to maintain the air filter element once a week. Unscrew the gland nut, take out the air filter element, blow out the dust particles on the outer surface of the air filter element from the inner cavity of the air filter element, and wipe the dirt on the inner wall of the air filter housing with a clean rag. Reinstall the air filter element, and pay attention to the sealing ring at the front end of the air filter element to fit tightly with the inner end face of the air filter housing.

When cleaning or replacing the air filter element, the parts must be matched one by one to prevent foreign matter from falling into the intake valve. Usually, you must check whether the air intake telescopic tube is damaged or flattened, and whether the connection between the telescopic tube and the air filter intake valve is loose or leaking. If found, it must be repaired and replaced in time.

Use a special wrench to remove the reverse oil filter element. It is best to add screw oil before installing the new filter element. Use both hands to screw the filter element seal back to the oil filter seat and tighten it firmly. It is best to replace the oil filter element at the same time when changing the engine oil. The replacement cycle should be shortened when used in harsh environments. It is strictly forbidden to use the oil filter element beyond the deadline. Otherwise, due to serious blockage of the filter element, the pressure difference exceeds the tolerance limit of the bypass valve, and the bypass valve automatically opens. A large amount of dirt and particles will directly enter the screw main unit with the random oil, causing serious consequences.

The quality of screw air compressor oil has a decisive influence on the performance of the oil-injected screw machine. Good oil products have good antioxidant stability, rapid separation, good foam removal, high viscosity, and good anti-corrosion performance. Therefore, users must use pure special screw air compressor oil from our company. The lubricating oil must be checked frequently during use. If the oil level line is too low, new oil should be added in time. It is strictly forbidden to mix different brands of lubricating oil. It is forbidden to use lubricating oil beyond the expiration date, otherwise the quality of the lubricating oil will decline, the lubricity will be poor, the flash point will be reduced, and it is very easy to cause high-temperature shutdown and cause the oil to spontaneously combust.

4.Sollant air compressor Maintenance and Replacement of Oil-Gas Separator

The oil-gas separator is a component that separates the lubricating oil of the screw air compressor from the compressed air. Under normal operation, the service life of the oil-gas separator is about 3000 hours, but the quality of the lubricating oil and the filtration accuracy of the air have a huge impact on its life. Therefore, the maintenance and replacement cycle of the air filter must be shortened in harsh use environments, and even the installation of a pre-air filter should be considered. Regular maintenance and timely replacement of the oil-gas separator not only extend the service life of the equipment but also enhance its working efficiency and reduce operating costs.

Coolers play a crucial role in the operation of screw air compressors, and ensuring their proper function can effectively prevent the equipment from overheating. Regularly inspect the cooler, clean the heat dissipation fins, and ensure cooling efficiency. Additionally, check the coolant level, and promptly add or replace the coolant to maintain the stability of the cooling system.

By strictly following the above maintenance guidelines, the service life of screw air compressors can be effectively extended, ensuring stable operation under various working conditions, improving production efficiency, and reducing maintenance costs. Let’s diligently carry out the daily maintenance of screw air compressors to ensure that the equipment is always in its best condition!
