The measurement accuracy is high, prompting insufficient information in time. The commercial tire pressure detector enables the driver to know the condition of the tire in time, which helps to avoid accidents.Manufacturers need to consider whether the tire pressure air tightness reaches IP67 waterproof level during production; the tire pressure detector does not have waterproof performance, and the water entering the tire pressure detector will be directly damagedsensor. In this way, when the tire is abnormal, it is easy to cause a traffic accident.Principle and test method of waterproof tester for tire pressure detector of commercial vehicle parts.

Air tightness test equipment for commercial vehicle tire pressure detector
carThe working principle of the tire pressure detector is based on pressure decay. Pressure decay refers to pressurizing the product to observe the pressure change of the gas. There are two situations here. One is that the product itself has an inflatable hole. We directly inflate and pressurize the product, then cut off the gas source and observe the change of gas pressure. If the pressure drops, the product is leaking and it is best not to fall. The second is that the product does not have a gas-filled hole, so we need to make a sealed cavity of the same size and size as the product, that is, a grinding tool, to fit the product as much as possible, because the test result is more accurate, and then pressurize the gas. The gas will fill the space between the product and the grinding tool, and then the gas will fill the space between the product and the grinding tool. At the same time, cut off the gas source and check whether the gas pressure drops. If there is a leak, the gas will leak into the product. Fortunately, there was no dripping.
Test product: Commercial tire pressure tester
The tire pressure detector tested in this test is completely sealed without any inflation holes. A mold must be made for the product. Place the tire pressure detector to be tested in the mold. The internal air pressure of the mold is inflated. Observe the change of air pressure in the mold from the instrument to judge whether the tested product is qualified. The Herris air tightness tester has a test accuracy of up to 1 Pa, and leaks that cannot be observed with the naked eye will be reflected in the instrument.
Air tightness test details
The waterproof grade required by the customer is IP68, which is the highest waterproof grade. It can easily solve the rain problem in the use of car tire pressure. According to customer test requirements, the product test pressure is 200KPa, the leakage limit is 0.1KPa, the air intake time is 5s, and the test time is 10s. According to the test requirements, qualified products, the test pressure can reach 200KPa, and the leakage value is not more than 0.1KPa, T When these two conditions are met at the same time, our air-tightness tester will automatically determine that the product is qualified, otherwise it will display the product leakage, and the device will beep to remind the operator. Haris air tightness tester is easy to operate. It only needs to set up a program according to the customer's test requirements. If the customer does not have test data, the test value of the customer's product can be set according to the customer's product.
HirisTechnology companies have conducted extensive airtightness tests on auto parts, gears, cars, wheels and new energy batteries. In terms of auto parts waterproof testing, there are rich cases and mature technology.
