How to check whether the water pressure and flow of the air compressor are normal?Atlas air compressor manufacturers introduce their testing methods for you, and follow the small series to understand it:
The inlet temperature of cooling water is generally not more than 35t, and the water pressure is 0.15^'0.Between 3MPa, the flow should not be less than 90% of the specified flow。Companies that use water-cooled compressors often have a separate cooling water system for the compressor, but share the same cooling system with other processes。Excessive links cause great impurities in cooling water, and form scale attached to the wall of a long cooling water pipeline, resulting in small water pipe passage, reduced water pressure, and insufficient flow。If the working environment does not meet the above requirements, it can be solved by installing cooling towers, improving indoor ventilation, and increasing the room space。If the intake and exhaust system and control pipe components are faulty or act insensitively, the compressor will work unbalance, resulting in high temperature。We can check them one by one by following the steps below。
1. Check whether the air filter is blocked. Whether the air filter is blocked can be checked or replaced according to the alarm signal of the differential pressure switch。
2, if the oil and gas separator is blocked, the compressed air is not discharged smoothly, it will cause the internal pressure to be too high, resulting in high temperature。The blockage of the oil and gas separator is mainly manifested as high internal pressure, so it is necessary to check and replace the oil core on time。
3, if the oil and gas separator is blocked, the compressed air is not discharged smoothly, it will cause the internal pressure to be too high, resulting in high temperature。The blockage of the oil and gas separator is mainly manifested as high internal pressure, so it is necessary to check and replace the oil core on time。
4, the smaller pressure valve failure causes the oil separator internal pressure rise Smaller pressure valve installed on the flat cover of the oil and gas separator, its role has the following aspects:
1, ensure that the starting priority to establish the pressure required for the lubricating oil cycle, to ensure the lubrication of the unit。
2, After the pressure reaches the small pressure valve set value, it can reduce the air flow rate through the fine oil and gas separator filter, ensure the effect of oil and gas separation, and make the oil and gas separation filter is not damaged due to too large pressure difference。
3, with the role of a check valve, the unit can prevent the compressed air in the pipe network from flowing back to the oil and gas separator and compressor host。
During the operation of the unit, the failure of the small pressure valve will cause the internal pressure of the oil separator to rise, and the lubricating oil cycle cannot be established preferentially when starting, and the effect of oil and gas separation will become worse, which is easy to cause the pressure difference of the oil and gas separation filter element to be too large and damaged, which is easy to cause the exhaust temperature of the unit to be high。
