The thin oil station is the heart of the thin oil circulation lubrication system, and its function is to forcibly press the lubricating oil to the friction parts of the machine.

[0003] When the existing high and low pressure thin oil lubrication station is working, the thin oil in the oil tank of the thin oil station is usually pumped out through the oil drain pipe by a pump, and then the thin oil is pressed to the friction part of the machine, and the amount of thin oil is monitored by a flow meter;

[0004] The existing high and low pressure thin oil lubrication stations have the following problems: the thin oil is stored in the oil tank of the thin oil station when not in use, and the temperature of the thin oil cannot be within the optimal working temperature range, which is inconvenient for the thin oil to be used at any time.
