The main reason for the high oil consumption of screw air compressor

2023-12-28

Excessive oil consumption of screw air compressor is a problem that many users will encounter. The general requirement of oil-gas separation of screw air compressor is that the oil content of compressed air after oil treatment should not exceed 3ppm. If the oil content of compressed air at the outlet of screw air compressor exceeds the standard, it is called high oil consumption, which is often called oil leakage. The common fault of oil leakage of air compressor will not only accelerate the consumption of engine oil, but also lose the function of lubricating oil. The main reasons for this situation are as follows:

1. The filter element filter has not been replaced for a long time. Regular replacement of filter element and filter is an important part of daily maintenance of air compressor. Inadvertent replacement will lead to filter failure, thus affecting the normal work of air compressor.

2. The oil-gas separator is damaged. The function of oil is to separate the oil in compressed air and prevent the oil content in compressed air from being too high. The damaged oil-gas separator will make the oil in compressed air exceed the standard, which will lead to an increase in oil consumption.

3. The oil return system is blocked. The blockage of the oil return system will also cause the oil not to come out, thus increasing the oil content in the compressed air. Cleaning the oil return pipeline can effectively solve this problem.

4. The oil content in condensate water discharged by steam trap is too high. If the oil content of the discharged condensate exceeds the standard, it is necessary to check whether there is any leakage point in the equipment and remove it.

5. The opening pressure of the pressure valve is abnormal. If the pressure valve cannot operate normally, it is necessary to detect whether there is a fault and replace the valve in time.

6. Quality of lubricating oil. Using the recommended brand of special lubricating oil for screw air compressor can effectively reduce fuel consumption.

7. The compressor oil level is high. If the compressor oil level is too high, it is necessary to remove the working pressure first and adjust the oil level to the normal range.

All these reasons will lead to the increase of oil consumption of screw air compressor, and regular maintenance can effectively prevent these problems.
