[0039] Working principle: When in use, the two springs 9 will apply continuous force to the inner wall of the conical groove 8 through the conical pressing sheet 5, so that the edge position of the oil-resistant piston 4 can continuously fit the inner wall of the air pressure pipe 3, and under the action of multiple fine grooves 10 on the inner wall of the air pressure pipe 3, the edge of the oil-resistant piston 4 can be deformed and recessed into a small part of the fine groove 10, which can increase the contact area between the oil-resistant piston 4 and the inner wall of the air pressure pipe 3, so that the oil-resistant piston 4 can move up and down more smoothly and sensitively.

[0040] Furthermore, when the level of the lubricating oil stored in the oil pump tank 2 floats up and down, the level of the lubricating oil in the air pressure pipe 3 can drive the oil-resistant piston 4 to rise and fall together. When the oil-resistant piston 4 rises and falls, the air pressure in the air pressure detection cavity thereon can change, and the arranged air pressure sensor 19 can detect the air pressure in its pressure detection cavity, thereby transmitting the data to the control panel 13.
