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 and leakage detection of the controller have become the key quality requirements of the controller. The IPX7 waterproof test level is generally used, and the IP waterproof test level is also used.

Do the controller IPX8 waterproof test, which is currently more popular.Air tightness detectorIPX8 waterproof test is carried out using the pressure drop method.

The IPx8 waterproof test is an international standard: it means that it is completely protected from the intrusion of foreign objects and dust, and can be submerged under specified water pressure indefinitely to ensure that it will not be damaged by water immersion.Since the IPX8 waterproof test level is relatively advanced, the water soaking method is difficult to implement, and batch waterproof testing and sealing testing cannot be performed.At present, the more scientific method is to use an air tightness detector to control theIPX8 waterproof test。

How to useAir tightness leak detectorRegarding the controller waterproof tester and IPX8 water test identification, please see the following introduction from Hai Ruisi:

First of all, we first understand the structure of the controller: if there is an inflation port, directly use air-tightness leak testing equipment to inflate the controller and test the air leakage rate of the controller to determine whether the controller reaches the original IPX waterproof level, thereby achieving the IPX8 waterproof test of the controller.

Thirdly, if the controller does not have an inflation port, you need to make a sealing detection tool, and then put the controller into the tool. The air tightness testing equipment inflates the sealing tooling and uses the gas to simulate the use environment of the controller. If the sealing is not good, air will leak into the interior of the controller, so as to test the air leakage rate of the controller and determine whether the controller reaches the original IPX waterproof level, thereby realizing the controller.IPX8 waterproof test。
