The shock absorber is used to suppress the shock of the spring when it rebounds after absorbing shock and the impact from the road surface.It is widely used in automobiles to accelerate the attenuation of vibrations of the frame and body to improve the driving smoothness of the automobile.
One of the important components of the shock absorber is the fluid reservoir.When working, the liquid reservoir is filled with oil, and the piston rod drives the piston to move up and down in the liquid reservoir, while the oil flows in the valve, thereby buffering the vibration during driving of the car.
The pressure on the inner wall of the liquid storage cylinder is relatively large. If the air tightness of the inner wall of the liquid storage cylinder is not enough, it will affect the normal use of the shock absorber.
What we are going to share today is aboutShock absorber reservoir air tightness testing case。
Testing instrument: HD-28 ingenuity seriesAir tightness detector。
Testing method: Customize different jigs and corresponding tooling according to the structure of different product models and customer needs.
Using the test method of semi-finished products and switching between positive and negative pressure, put the product to be tested into the mold and press the start button of the tooling to start testing.The negative pressure is -0.2Kpa, the upper limit of leakage is 200pa; the high pressure is 300Kpa, the upper limit of leakage is 100pa.The test duration is 264.6s.
During the test, if the value exceeds the set value, the product to be tested is a defective product, otherwise it is a qualified product.
