On the important principles of screw air compressor maintenance

　　Regarding the important aspects of screw air compressor maintenance, screw air compressor three filters and one oil, refers to screw air compressor air filter, oil filter, oil and gas separator and screw air compressor oil four consumables, air compressor regular maintenance work is to replace these accessories. If the screw air compressor is well maintained and properly maintained, it will bring twice the effect to your production with half the effort; On the contrary, if the maintenance is not timely, the air compressor will make some emotions with you from time to time, and lying on the nest is also a common thing. Zhigao screw air compressor is looking for us Hunan Ruisheng Electromechanical Equipment Co., Ltd., our official website is www.hnzega.com.
　　
　　First, the replacement of screw air compressor oil filter
　　
　　The running-in period of the first operation of the new machine is generally 500 hours, and the oil filter needs to be replaced. It is recommended to replace the new oil filter every 2000 hours or so, it is best to replace the oil filter at the same time when changing the oil, and the replacement cycle should be shortened when used in a bad environment. The service life of oil filter and screw air compressor oil has a great relationship with the cleanliness of the air filter. It is strictly forbidden to use the oil filter element beyond the deadline, otherwise due to the serious blockage of the filter element, the pressure difference exceeds the limit of the bypass valve, the bypass valve will automatically open, and a large amount of stolen goods and particles will directly randomly enter the screw air compressor host, causing serious consequences.
　　
　　Second, the maintenance and maintenance of screw air compressor air filter element
　　
　　The air filter element is the gatekeeper who filters out air impurities, and the filtered clean air enters the screw rotor compression chamber for compression. Because the internal gap of the screw air compressor is only allowed to filter out particles within 15υm. If the empty filter element is blocked and damaged, a large number of particles greater than 15u enter the screw host to circulate, which will not only shorten the service life of the oil filter element and the oil and gas separation core, but also cause a large number of particles to directly enter the bearing cavity, accelerate the bearing wear to increase the rotor clearance, reduce the compression efficiency, and even the rotor bites. Therefore, the air filter element should be maintained once a week, and the dust particles on the outer surface of the air filter element should be blown out from the inner cavity with compressed gas. The air filter element is replaced once in 1000-2000 hours under normal conditions, and the use of places with particularly harsh environments, such as mining, paper industry, and textile industry, it is recommended to replace the air filter every 1000 hours. 　　Third, the maintenance and replacement of screw air compressor oil and gas separator
　　
　　The function of the oil and gas separator is to separate the oil and gas mixture. Under normal use, the life of the oil fine separator is about 3000 hours, but the quality of lubricating oil and the filtration accuracy of air have an important impact on its life. In harsh environments, the maintenance and replacement cycle of the air filter element must be shortened. The oil and gas separator must be replaced after about 3000 hours or the pressure difference before and after exceeds 0.12Mpa. Otherwise, it will cause the motor to be overloaded, the current is too large, the electricity is consumed, and the oil fine separator is easy to break the running oil.
　　
　　4. Maintenance and replacement of screw air compressor oil
　　
　　The quality of screw air compressor oil has a decisive impact on the stability of the oil-injected screw air compressor, good oil has good oxidation resistance, fast separation, good foaming, high viscosity, good anti-corrosion performance, therefore, users must use special screw oil that matches the equipment. The first oil replacement is carried out after the running-in period of 500 hours of the new machine, and the new oil is replaced every 2000 hours or so after operation. It is best to replace the oil filter at the same time when changing the oil. Use in harsh environments to shorten replacement cycles.
　　
　　If the air compressor oil is replaced in the cold machine state, the air compressor should be started to run for 5 minutes to reduce the viscosity of the oil. Stop running completely, open the drain valve at the bottom of the oil and gas barrel, and connect the oil storage tank. The oil drain valve should be opened slowly to avoid splashing the human body with pressure and warm lubricating oil. During use, it must be checked frequently, and new oil should be replenished in time when the oil level line is too low, and condensate must also be frequently discharged in the use of lubricating oil, which is generally discharged once a week, and should be discharged once in 2-3 days in a high temperature climate. Lubricating oil is strictly forbidden to mix different brands, avoid the use of lubricating oil beyond the deadline, otherwise the quality of lubricating oil will decrease, the lubricity will be poor, and the flash point will be reduced, which will easily cause high temperature shutdown and cause spontaneous combustion of oil.
　　
　　Fifth, the daily maintenance of screw air compressor cooler
　　
　　It should be emphasized here that the daily maintenance of the screw air compressor cooler is also very important, and the heat dissipation effect directly affects the operating temperature of the air compressor. The plate-fin structure tends to collect dust, so the cooler maintenance needs to be regularly purged with dry compressed air. If the screw air compressor is used in a relatively harsh environment, the surface of the cooler is full of oil and can not be blown clean, then the radiator should be removed and washed with high-pressure water to wash the car to restore the cooling effect of the screw air compressor radiator.
