Compressor crankshaft mailbox
Thread Content
This is the mailbox at the crankshaft of the compressor in our factory. What is it for? What's the use?
Of course the fuel tank stores oil and lubricates it.
After lubricating each equipment point, the lubricating oil will be refilled into the oil tank, and then pumped to each lubrication point by the oil pump.
The protruding one is a twin-screw shaft head pump, which is connected to the crankshaft and driven by the motor. The auxiliary oil pump supplies oil to the unit before starting up. After starting up, the auxiliary oil pump stops working when it reaches normal speed, and the screw pump supplies oil.
Since there is already a mailbox at the auxiliary oil pump, why do we need to design an oil tank at the crankshaft?
The basic function of the oil tank is to store oil, and then pretreat the oil (including changing the oil inlet temperature, filtering, etc.) so that suitable oil can enter each lubrication point.
If there is an auxiliary oil tank, the oil tank of the body itself is used to recover various lubrication points.
Do you mean that it only has a collection function and is not actually a fuel tank? Right.
It's not a fuel tank, let alone a mailbox, it's just a pump head for pumping out lubricating oil!
