Diaphragm compressor oil pressure issues
Thread Content
The lubrication oil pressure in the diaphragm compressor fails to reach the required level; it can reach 4 kilograms when the oil pump is first started, but it drops below 2 kilograms after just 2 minutes of operation, or even lower. The imported filter has been cleaned. What other reasons could there be? How to solve it?
This compressor has medium pressure, diaphragm operating oil pressure, and lubricating oil pressure. The actual working oil pressure is related to the system. As a mere lubricating pressure, for lubricating reducers and the like, 2 kilograms of pressure is quite high.
For units with a lubricating oil pressure of simply 3 kilograms, an alarm is triggered; the machine shuts down automatically when the pressure drops to 2 kilograms. Mainly, it can reach 4–6 kilograms right after the oil pump is started, and then it drops rapidly.
Could the problem with the four-way three-way valve in the oil pump of a diaphragm compressor arise here? ? ?
