Controller waterproof test equipment

controller防水测试设备, controllerIpx8 waterproof tester密封性检测The use method and the process of air tightness leak detection

As the core component of the product, the controller is not waterproof, which causes many problems. Because of the waterproof test of the controller, the air tightness leak detection of the controller has become the key quality requirement of the controller. Generally, ipx7 waterproof test level is used, and some use IP waterproof test level.

Do controller ipx8 waterproof test, the more popular气密性检测仪Ipx8 waterproof test was carried out in the way of pressure drop.

Ipx8 waterproof test is an international standard: it means to completely prevent the invasion of foreign objects and dust, sink indefinitely under the specified water pressure, and ensure no damage caused by immersion. Because ipx8 waterproof test level is relatively advanced, water soaking method is difficult to achieve, and batch waterproof test and sealing test cannot be carried out. At present, the more scientific method is to use air tightness detector to controlIpx8 waterproof test

Appearance of air tightness leak detector

IPX8防水测试

Parameters of air tightness leak detector

Air supply pressure: 0.4 ~ 1.2MPa

Power supply voltage: 220 V / 50 Hz or 110 V / 60 Hz

Pressure regulation range: - 40 ~ - 0.5kpa, 5 ~ 150kPa

Pressure regulation accuracy: 0.1kpa

Pressure test range: - 80 ~ 150kPa

The minimum resolution of pressure attenuation test is 1pA

Minimum resolution of leakage flow test: 0.01ml/min

How to use气密性检漏仪For the controller waterproof tester, ipx8 water test and identification, please see the following introduction of Harris:

First of all, let's understand the structure of the controller: if there is an air filling port, the air leakage rate of the controller can be tested by directly using the air tightness leakage detection equipment to determine whether the controller reaches the original IPX waterproof level, so as to realize the ipx8 waterproof test of the controller.

Thirdly, if the controller does not have an inflation port, it is necessary to make a sealed detection tool, and then put the controller into the tool. The air tightness test equipment flushes the sealing tooling and uses the gas to simulate the operating environment of the controller. If the air tightness is not good, the air will leak into the controller, so as to test the air leakage rate of the controller, And determine whether the controller reaches the original IPX waterproof level, so as to realize the controllerIPX8防水测试

The air tightness test method is also applicableWaterproof test of mobile phone, camera waterproof detection, cavityAir tightness leak detection equipment, waterproof test of charging pile, waterproof test of charging gun, etc
