    Air leak testing of Pet tracker

    2018-12-10

    Testing principle

    Hairuisi sealing tester is a new ,high precision and non-destructive air leak tester .Our air leak tester adopts pressure principle and uses compressed air as the medium to detect leaks. It is a non-destructive testing instrument. The working principle is to apply a certain pressure to the inner cavity or outside of the product to be tested, then close the valve. After a period of stability, measure the change of the air pressure during the detection period and calculate the leakage amount by our precision sensor.This instrument is widely used in the sealing test of open products or sealed products with its high precision and full-featured features.


    ♦Product description 

    Speaking of pet dog trackers, the first thing we should consider is anti-falling and waterproof, because dogs are not so obedient.If the pet is outdoors, there will always be rain or splashes. so it is necessary to test the tightness of the dog tracker, which is related to the service life of the pet tracker .

     

    Pet dog tracker shape and detection points analysis

    The product is rectangular, tightly structured, with rubber paint on the surface of the shell,.Since the testing product don't have Inflatable mouth.Hairuisi Technology needs to customize a suitable mold .The mold is fixed to the tooling to detect the product 's waterproof .The mold is divided into upper and lower parts. When the upper and lower molds are closed, a sealed space can be formed. At this time, the instrument will inflate the mold, and the sealed space is beneficial for monitoring the change of the air pressure in the pet tracker  .

    The following is the mold of pet tracker .


     

    ♦Testing process 

    1.Connect the leak tester to the power supply and air supply.At the same time,the fixture and the tester are also connected through the air source,

     so that the our air leak tester can control the fixture.

    2.Acoording to the customer's testing requirements and our test experiments on products in the early stage to set the testing parameters on our air leak tester .

    3.Put the testing product in the mold and press the start button .the fixture will seal the mold and Certain compressed air will be input from our instrument into the mold.

    when input air time finished ,The valve will close and our instrument will measure the change of the air pressure during the detection period and calculate the leakage amount by our precision sensor.


    when the testing time is finished ,The testing result (OK or NG )will be shown on our screen .

     

     

    Display of air tightness testing system

    Pet dog tracker air tightness testing system is divided into three parts: tester, air source, tooling. Because the tester, air source and tooling are self-contained, they cooperate with each other in the detection, but they do not affect each other, which improves the accuracy of  seal detection. If matched with different tooling, different types and sizes of products can also be detected, and the applicability of the equipment is high. The following is the actual picture of the air tightness detector.
