The Design Of The Electromagnetic Valve Detecting Instruments

With the development of automotive control technology, there are more and more solenoid valves used in vehicles. Also, the quality of solenoid valves is required more and more higher.In modern vehicles, solenoid valves are applied in so many places, such as in controlling oil, gas valves on or off and the brake. The capability of solenoid valves is directly related to vehicle performance, or even related to the safety of drivers. Therefore, the quality of solenoid valves is very important.At present, the domestic solenoid valve detector is a manual inspecting platform. This inspecting platform exit some limitations, such as the complexity of operation, the higher requirement to the detection staff, needing the detection staff focus on pressure gauge at all times, the very larger labor intensity and the slower speed to the operator, particularly in the detection accuracy the effects not to be satisfactory and so on. In the developed countries, the solenoid valve detectors are all self-developed automatic detection platform, but not general-purpose product. Therefore, research the automatically detecting platform owned to China intellectual property rights, which is great significant to promote the development of China automobile industry.The controlling core of the solenoid valve detector is a MCU, coupled with forward sample channel, control module, display module, which automatically detect solenoid valve strictly according to the testing norms. It makes the solenoid valve failures be clear at a glance, and ensures the quality of the products.After our efforts in several months, the development and debugging of the solenoid valve detecting platform have been completed. Now, the solenoid valve detector has been installed on the product line. After a long period of operation, it is proved that the solenoid valve detector runs stably, which reaches to the desired effect.
