As oil prices continue to rise, new energy vehicles are gradually becoming more and more popular among consumers.What drives electric cars is electricity.Electrical energy is generated by the car's motor converting electrical energy into mechanical energy or converting mechanical energy.

If the air sealing of the motor is not done properly, it will easily affect driving safety and road safety.

Today we are sharing aboutMotor air tightness detectorcase.

Testing equipment: HC classic seriesAir tightness detector

Based on the structure and shape of the motor, we selected the detection method for finished product and large leakage volume determination, and customized supporting tooling and fixtures.

Place the product to be tested into the fixture and fix it, select the set program, and press the instrument start button to start testing.The quantitative air intake time is 5S and the partial pressure time is 5S. During this period, the equipment inputs a certain air pressure and monitors it for a certain period of time. The change in volume is calculated through the formula set in the instrument. If the volume does not exceed 400ML, it is determined that the product has not leaked.At this time, proceed to the next micro-leakage test and start inflating. After 8 seconds, ensure that the air pressure in the cavity reaches 15kPa. Stop inflating and enter the pressure stabilization stage. Start testing after 12 seconds. After 5 seconds, the instrument determines whether the leakage value exceeds 10Pa. If not, the test product is qualified.
