The working principle is as follows:

when the lubricating oil is pumped from the oil drum through the high-pressure pump 12 and injected under pressure into the flow rate detecting device 2, the lubricating oil has a rated pressure, for example, 40 MPa. The lubricating oil is injected from the oil inlet hole 211 into the main bore 21, and flows into the cavity of the plunger bore 22 through the main bore 21 and the control bore. After the flow rate detecting device 2 is filled with the lubricating oil, the working plunger 221 closest to the oil inlet hole 211 is pushed under pressure, and the lubricating oil at one end of the plunger hole 22 is squeezed out and flows out through the oil outlet pipeline 24 at the end far away from the oil outlet hole 241. At this time, the other end closest to the oil inlet hole 211 is filled with the lubricating oil through the main port passage 21 and the oil outlet pipe 24, and applies pressure to the adjacent plunger hole 22 through the main port passage 21 and the pilot port passage.

Since the working plunger 221 is a magnetic member, the plunger movement detecting device 3 is provided on the outer side wall of the plunger hole 22 to detect the movement of the working plunger 221, so that the number of times of movement of the working plunger 221 can be accurately known, and the amount of oil flowing through the flow rate detecting device 2 can be calculated. The plunger movement detecting device 3 transmits the detected signal to the control chip 31, and the control chip 31 calculates the oil amount and controls the display device 311 to display the oil amount. Meanwhile, the control chip 31 sends the signal to the signal transceiver 4 through the communication device 312, the signal transceiver 4 transmits the signal to the microprocessor chip 41, and the display operation device 411 is controlled by the processing chip to display the signal, so that an operator can know the oil amount at one end of the oil gun 14.
