The car gearbox is a control device that changes the speed ratio and direction of movement of the car. It is located between the car's engine and drive wheels, that is, under the gear lever.Excellent oil and water resistance are required to ensure driving safety.

Below, Hirays Technology will show youAutomobile gearbox air tightness testingcase.

The customer has high waterproof requirements for this gearbox product, requiring the test pressure to reach 30Kpa and the upper limit of leakage not to exceed 30pa.

Equipment used: Hirays HP development seriesAir tightness detector

Detection method: Direct testing method is adopted. According to the structure of the automobile gearbox, we recommend to customers to use a quick connector to block the controller.

Program parameters: intake pressure 30Kpa, intake time 10s, pressure stabilization 30s, test time 5s, deflation time 5s.If the leakage value does not exceed 30pa, indicateCar gearbox waterproof testingPassed, the test result will also show OK.

Fortunately, our company's equipment finally met the customer's requirements for this gearbox product.
