Abstract

The invention discloses a detecting device for a sealing property of a motor. The detecting device comprises a motor putting device and a leakage detector, wherein the motor is arranged in a detected sealing chamber of the motor putting device; the leakage detector comprises a shell, an air-path system and a control system; the air-path system and the control system are arranged in the shell; the air-path system comprises a filtering pressure-regulating valve, a first air inlet solenoid valve, a pre-aerating container, a second air inlet solenoid valve, an exhaust solenoid valve, a controller component, a pressure sensor and a differential pressure sensor; the control system comprises a programmable controller, a switching power supply, a relay and a touch screen; a user can observe the change of parameters, such as time, pressure, a differential pressure value and leakage rate, during a detecting process, and a final detection result on the touch screen, also can set the detecting parameters and can look over historical detecting records. The detecting device for the sealing property of the motor has the advantages that the whole sealing property of the motor can be objectively detected, the detecting efficiency is high, and the detecting site is clean.

Description

technical field [0001] The patent of the present invention relates to a detection device, in particular to a motor sealing detection equipment. Background technique [0002] Automobile or motorcycle starter motors have high waterproof requirements. If the airtightness is not good, the motor will be easily damaged due to short circuit due to water ingress. Therefore, it is very important to carry out the motor sealing test. The traditional detection method is to use the vacuum water detection method, which is to put the product under test into a sealed container filled with water, and use a vacuum pump to pump out the air on the water surface. If bubbles can be observed, it means that the motor is leaking, otherwise the motor is sealed. Good performance, after the inspection is completed, take out the motor, blow off the water droplets on the surface with an air gun, and flow into the next process. [0003] The traditional water inspection method has the disadvantages of bei...
