Inside cavities of the oil suction valve 8.1 and the oil discharge valve 9.1 are respectively provided with an oil suction valve core 8.1.1 and an oil discharge valve core 9.1.1. Among them, the crankshaft 3 is installed on the top surface of the support frame 1 through a bearing seat, the motor 2 is fixed at one end of the top surface of the support frame 1, and the oil tank 7 is arranged at a position corresponding to the motor 2 on the front side of the support frame 1. The input end of the oil suction pipeline 8 is connected to the outside of the middle part of the front wall of the oil tank 7, and the output end of the oil discharge pipeline 9 is connected to the inside of the middle part of the top surface of the oil tank 7. The outer shell of the plunger 6 is connected to the output end of the oil suction pipeline 8 through the oil suction valve 8.1 and is connected to the input end of the oil discharge pipeline 9 through the oil discharge valve 9.1. The motor 2 drives the crankshaft 3 to rotate through a coupling, and the rotation of the crankshaft 3 drives the slider 5 to perform reciprocating motion back and forth through the crank 4, so as to realize the reciprocating motion of the plunger 6 along its outer shell, and then cooperate with the oil suction valve core 8.1.1 in the oil suction valve 8.1 and the oil discharge valve core 9.1.1 in the oil discharge valve 9.1 to realize the process of oil suction and oil discharge.

[0034] A torque speed meter 10 is connected between the power output shaft of the motor 2 and the crankshaft 3. The torque speed meter 10 measures the changes in the torque and speed of the power output shaft during the operation of the motor 2.

[0035] To accurately monitor the phase angle of the crank and the phase difference between them, laser emitters 11 are respectively installed in the middle of the side of the crank 4 away from the slider 5; the bottom end of the laser receiving plate 12 is fixed at the rear end of the support frame 1 at a position corresponding to the crank 4; the laser receiving plate 12 extends vertically, and a plurality of laser receiving elements are integrated on its front wall to form a laser detection system, that is, a non-contact phase detection system. This laser detection system determines the longitudinal position of the crank 4 by detecting the presence or absence of laser and judges the lateral position of the crank 4 based on the change in the intensity of the laser.

[0036] A flow sensor 8.2 and a pressure sensor 8.3 are installed on the oil suction pipeline 8 to monitor and record in real time the flow rate change and pressure state of the oil in the oil suction pipeline 8. A displacement sensor 8.1.2 and a vibration sensor 8.1.3 are installed on the oil suction valve core 8.1.1 to monitor the working state of the oil suction valve 8.1.
