There are various reasons for the oil in the exhaust gas of the screw compressor during operation. Different reasons require different treatment methods. The following briefly talks about common troubleshooting methods.
First, the problem of oil separation core damage in screw air compressor
The damage of the oil separation core of the screw air compressor is a common phenomenon, so the equipment needs to be inspected before the operation of the screw air compressor. During use, it should be strictly carried out in accordance with the operating procedures. After use, the equipment should be regularly maintained. If the oil separation core is found to be damaged and perforated, it should be replaced in time to ensure the normal operation of the equipment.
Second, there is a problem with the oil return line of the air compressor
During the operation of the screw air compressor, if the return oil pipeline is blocked, it is necessary to check the pressure drop of the separator first. If there is no problem with the pressure drop, the oil separator core needs to be cleaned. If there is a problem with the oil separator core, it must be replaced in time.
Third, the problem of low system pressure control
For operators, they should be familiar with the control pressure of the equipment. If problems are found, the load of the system should be reduced so that the system pressure reaches the rated working pressure.
Fourth, the problem of minimum pressure valve failure
In actual operation, if the minimum pressure valve is found to be ineffective, it must be replaced before working.
Fifth, the problem of adding too much cooling oil to the compressor
When adding cooling oil to the compressor, you should first understand the normal value of how much cooling oil the equipment should add. There should be a dedicated person responsible for adding cooling oil, and generally it should be added to the appropriate position according to the manufacturer's requirements.
Sixth, the problem of cooling oil quality
The addition of cooling oil should be strictly in accordance with the equipment's requirements for cooling oil, because different equipment has different requirements for cooling oil. After adding, the addition time should be recorded, and when the cooling oil reaches the service life, it should be replaced on time. The addition of cooling oil and the quality of cooling oil should be strictly in accordance with the manufacturer's requirements.
