The controller refers to the master device that changes the wiring of the main circuit or control circuit in a predetermined sequence and changes the resistance value in the circuit to control the starting, speed regulation, braking and reverse direction of the motor. It is also the "decision-making body" that issues commands.When in use, people will pay more attention to the sealing condition of the controller. Generally, the sealing test of the controller adopts IPX8 as the maximum test level. Currently, the simplest test method is to use the pressure drop method in the air tightness detector to perform IPX8 test.

Hairis Technology has also conducted in-depth research on the sealing testing of controllers and has made many achievements in the field of sealing testing of controllers. This time we will share a case of sealing testing of controllers for your reference. We hope it will be helpful to you.

Controller air tightness detector

1. Display of the controller’s appearance and detection difficulties

1. What we want to test this time is an ordinary controller. Its shape is a regular rectangular parallelepiped. There are three docking ports in front of the controller. The whole controller is wrapped with waterproof material and has strong sealing performance.

2. Such a shape is unfavorable for the sealing inspection of the tooling, and it is easy to cause deviations in the inspection results due to air leakage.

2. Breakthroughs in controller detection difficulties and demonstration of the detection process

Controller air tightness testing mold display

Faced with this situation, Hairis specially used a mold specially designed to hold this type of controller. In this way, the mold can well fix the controller. After the upper mold is closed downward, a closed detection space will be formed, which is conducive to indirect detection of the controller, protection of the controller, non-destructive testing, and reduction of enterprise costs.

Details of the controller’s air tightness testing tooling

At this time, after the tooling connected to the mold is started, a certain volume of gas is injected into the mold through the air source. When the detected air pressure is reached, the air supply is automatically cut off and the air tightness detection system enters the pressure stabilization stage. The Hairis Technology air tightness detection system will monitor the air pressure in the mold and determine the tightness based on the amount of leakage.

3. Controller sealing tester parameter table

1. High-sensitivity pressure sensing and adjustment unit, combined with advanced differential pressure software algorithm, the minimum resolution can reach 0.1Pa. This algorithm has obtained a national patent.

2. The patented technology independently developed by Hairuisi, "IVT pneumatic sealing valve island", greatly improves the test accuracy, ensures the stability of the instrument, and greatly improves the inflation speed.
