Atlas air compressor maintenance basics include: air filter replacement, maintenance; oil filter replacement, screw air compressor oil replacement; oil and gas separation core replacement and maintenance; cooler maintenance and maintenance.
1, Atlas air compressor maintenance air filter maintenance and maintenance.
The function of the air filter is to filter out dust and dirt contained in the intake air, and send the filtered clean air into the screw rotor compression chamber for compression. Because the internal clearance of the screw machine only allows particles within 15u to filter out. If the air filter plug is broken, a large number of particles larger than 15u will enter the screw machine to circulate, which will not only shorten the service life of the oil filter element and the oil separation core, but also lead to a large amount of particles directly entering the bearing cavity, accelerating the wear of the bearing and increasing the clearance of the rotor. The compression efficiency is reduced, even the rotor is dead. Atlas air compressor maintenance Atlas air compressor maintenance air filter is best to maintain once a week, unscrew the gland nut, remove the air filter, with 0.2-0.4Mpa of compressed air, from the empty filter cavity Blow out the dust particles on the outer surface of the air filter and clean the dirt on the inner wall of the air filter housing with a clean rag. Return air filter, note that the sealing ring at the front end of the air filter fits tightly with the inner end face of the air filter housing. The maintenance of the diesel air intake air filter core of the diesel power screw machine should be synchronized with the air compressor air filter core, and the maintenance method is the same.
The new air filter should be replaced after running for 500 hours during the run-in period, and it should be replaced after 3000 hours under normal conditions. If the screw air compressor is operated in a particularly harsh environment, such as mines, pottery factories, cotton mills, etc., it is recommended to replace it every 500 hours. Air filter.
When cleaning or replacing the air filter, the parts must be in one pair to prevent foreign matter from falling into the intake valve.
Normally, the intake bellows must be inspected for damage and squeezing. The Atlas air compressor must be inspected for any looseness or leakage of the connection between the bellows and the air filter intake valve. If found to be promptly repaired and replaced.
2. Replacement of oil filter.
Atlas air compressor maintenance new machine run 500 hours after the run-in period should be replaced engine oil core, with a special wrench reverse spin oil filter removed, the new filter before loading the best screw oil, filter cartridge seal with both hands back to the oil filter Seat, tighten firmly.
It is recommended to replace the new filter every 1500-2000 hours. It is best to replace the oil filter at the same time when changing the oil in the Atlas air compressor. When the environment is bad, the replacement cycle should be shortened.
Atlas air compressor maintenance is strictly prohibited overrun oil filter, or because the filter plug is serious, the pressure difference exceeds the bypass valve to withstand the limit, the bypass valve automatically opens, a lot of stolen goods, particles will be directly random oil into the screw host, causing Serious consequences.
(The diesel engine oil filter and the diesel filter should be replaced by diesel engine maintenance requirements. The replacement method is similar to that of the screw oil core.)
3, Atlas air compressor oil maintenance and replacement.
The quality of Atlas air compressor oil has a decisive influence on the performance of the oil injection screw machine. Good oil has good anti-oxidation stability, rapid separation, good defoaming, high viscosity, and good anti-corrosion performance. The user must use genuine screw air compressor oil for the company.
The first oil replacement is performed 500 hours after the start-up period of the new machine, and the new oil is generally replaced every 3000 hours of operation. (However, depending on the quality of the oil you purchase, the maintenance cycle is different. All-synthetic oils can generally be replaced in 4000-8000 hours. Semi-synthetic oil is generally replaced in about 3,000 hours. Mineral oil is generally replaced in about 2000 hours.) At the same time replace the oil filter. Use in a harsh environment to shorten the replacement cycle.
Replacement method:
The air compressor was started for 5 minutes to increase the oil temperature to above 50°C and the oil viscosity decreased.
Stop running. When there is a pressure of 0.1Mpa in the oil and gas tank, open the drain valve at the bottom of the oil and gas tank and connect it to the Atlas oil storage tank. The drain valve should be opened slowly so as to avoid splashing the dirt with the pressurized lubricant. After the lubricating oil drops into shape, close the drain valve. Unscrew the oil filter, put the lubricant in each pipe at the same time and replace with a new oil filter.
Open the filling screw plug and inject new oil so that the air compressor oil level is within the marking range of the oil scale. Tighten the filler plug to check for leaks.
The lubricating oil must be inspected frequently during use. If the oil level is too low, it must be replenished with new oil. The lubricating oil must also be drained regularly during the use of the lubricant. The Atlas air compressor maintenance is normally discharged once a week. In hot climates, it should be discharged in 2-3 days. Stop for more than 4 hours. Open the drain valve without pressure in the oil and gas tank, drain the condensate, and quickly close the valve when the organic oil flows out.
Lubricating oil is forbidden to be mixed with different brands. Do not use lubricants for extended periods of time. Otherwise, the quality of lubricants will be reduced. Lubricity will be poor, and the flash point will be reduced. This will easily cause high temperature shutdown and cause spontaneous combustion of the oil.
4. Maintenance and replacement of oil and gas separators.
The oil-gas separator is a component that separates the Atlas air compressor lubricant from the compressed air. Under normal operation, the service life of the oil-gas separator is about 3,000 hours, but the quality of the lubricant and the air filtration accuracy have a long life. big influence. It can be seen that in the harsh environment of use, it is necessary to shorten the maintenance and replacement cycle of the air filter, and even consider the installation of a pre-air cleaner.
Oil and gas separators must be replaced after expiration or after the pressure difference exceeds 0.12 MPa. Otherwise, the motor will be overloaded and the oil separator will break and run.
Replacement method:
Remove the control pipe fittings installed on the gas tank lid of the Atlas air compressor. Take out the oil return barrel and extend it into the oil return pipe in the oil and gas tank, and remove the oil tank top cover fastening bolts.
Remove the lid of the oil and gas tank and remove the oil separator. Remove the asbestos pad and dirt stuck on the top cover.
Install a new oil and gas separator, air compressor maintenance Note that the upper and lower asbestos mats must be stapled, and the asbestos mats must be neat when pressed, otherwise it will cause cushioning.
Replace the upper cover plate, return oil pipe, and each control tube as they are and check for leaks.
5, cooler maintenance.
Atlas Air Compressor Maintenance Observing the cooling effect of the cooler directly affects the use temperature of the air compressor. The plate-fin structure is easy to gather dust, so the cooler maintenance needs to use 0.4 Mpa dry compressed air per shift from top to bottom. The diesel-driven screw cooler is upright. When it is maintained, dry compressed air of 0.4Mpa or more is needed to blow from the outside. After blowing, the dust and particles in the air-guiding hood should be cleaned to prevent them from being fanned again. Blowing into the cooler causes a blockage, causing the machine to heat up. Atlas compressor maintenance If used in harsh environments, the cooler surface is full of oil, it must be cleaned with carbon cleaning agent.
