During the operation of the screw compressor, if the oil separation core appears damaged, such as breakage or perforation, then it loses the effect of oil and gas separation. That is to say, if the mixed gas and the exhaust pipe of the compressor are directly connected, a large amount of cooling oil will not be separated, and will be discharged from the body together with the gas, causing oil leakage during the exhaust process.

During the operation of the screw compressor, the oil return pipeline plays an important role. There will be a pressure difference between the inside of the oil separation core and the compressor inlet. Under the effect of this pressure difference, the oil return pipeline is responsible for transferring the oil. The oil collected at the bottom of the separation core is sent back to the compressor for continued use in the next cycle. If the oil return line has problems such as blockage, cracking, incorrect installation, etc., the oil collected at the bottom of the oil separation core cannot be transported back to the compressor, causing too much oil to accumulate at the bottom. Then this part of the oil has not been transported back to the compressor. As the gas is discharged, oil will appear during the exhaust process.

During the operation of the screw compressor, if the system pressure is controlled too low, it will cause the centrifugal force in the separator to be less than the operating required centrifugal force. Then the effect of the separator will not be reflected, which will cause the separator core to enter the next stage. The oil content of the gas in the compressor is too high and exceeds its separation range, which leads to incomplete separation of oil and gas, and oil problems occur during the exhaust process of the compressor.

During the operation of the screw compressor, the function of the minimum pressure valve is to ensure that the system pressure is controlled above the minimum pressure during operation. If the minimum pressure valve fails, the minimum pressure of the system will not be guaranteed. Because the gas consumption of the operating equipment is very large, the system pressure will be too low and the oil return pipeline will not be able to return oil. The oil collected at the bottom of the oil separator core will not be able to be returned to the compressor, and will be discharged from the compressor along with the compressed gas, causing oil problems during the flat exhaust process.

Before the operation of the screw compressor, too much cooling oil is added, which exceeds the range of the compressor. During the operation of the compressor, because the oil level is too high, even though the separation system separates the oil and gas, the gas emissions will be reduced. In the process, the gas will also entrain the cooling oil into the gas and discharge it, causing the oil content in the discharged gas to be too high and causing oil entrainment problems.
