Why is the liquid level in the oil tank of a screw compressor dropping rapidly?
Thread Content
It’s operating normally, and there are no leaks in the oil system, but the oil level in the tank drops quite quickly. What could be the reason?
Is it an oil-injected screw compressor? Check whether the outlet pipeline is contaminated with oil, and inspect the oil separator filter element.
Is the oil separator part in good condition?
Check whether your oil separator is functioning properly!
If the pressure and oil circuit are normal, it’s very likely that it went out along with the gas. Check the oil separator and the minimum pressure valve.
Fault symptoms: High fuel consumption by the unit or high oil content in the compressed air; excessive amount of cooling fluid. The correct level should be checked when the unit is under load, at which point the oil level should not exceed half of the container’s capacity； ·Oil return pipe blocked ； ·The installation of the return oil pipe (distance from the bottom of the oil separation element) does not meet the requirements ； ·The exhaust pressure is too low while the unit is operating ； ·Oil separation core is broken ； ·The partition inside the separation cylinder is damaged ； ·There is oil leakage from the engine unit ； ·The coolant has deteriorated or been used beyond its expiration date.
