Equipment and method for detecting air tightness of shaft seal lip of shaft seal for vacuum pump

The invention discloses a vacuum pump shaft seal lip air tightness detection device, which comprises a detection mechanism, a control mechanism and a terminal system, and is characterized in that the detection mechanism is used for detecting the air tightness of a shaft seal lip, and the control mechanism is used for controlling and monitoring the air pressure, the air flow rate and the temperature in the detection process of the detection mechanism; the terminal system is used for controlling the detection mechanism and the control mechanism, transmitting data, recording and alarming and scramming, the detection mechanism comprises a heating base, a medium load body, a shaft sealing ring, a sealing plate, a tool shaft, a motor stator and a motor rotor, and a plurality of mounting holes are formed in the heating base. The air tightness of the shaft seal lip of the shaft seal for the vacuum pump is accurately detected, the simulated working state of the shaft seal is detected, and the situation that dust in a
