Description

Technical Field

[0001] The utility model relates to the field of filter seat testing equipment, in particular to a pressure testing fixture for processing module filter seats. Background Art

[0002] An automotive module filter seat generally refers to the base part for installing a filter, which plays a role in fixing and supporting the filter, and also has designs and functions related to connection and sealing with other systems, etc., while maintaining the compactness and efficiency of the system. To prevent the reliability of the automotive module filter seat and verify its structural strength, one of the main functions of the filter seat is to ensure the sealing between the filter and the engine or other systems. Pressure testing can verify whether the filter seat can maintain good sealing under working pressure and prevent leakage of oil, air or coolant.

[0003] Currently, most of the pressure testing equipment for module filter seats uses a pressure applying device to input a set pressure into the interior of the module base, and then it is placed in water to observe whether there is air leakage to judge its sealing performance. Usually, pressure is applied to several input ports of the module base. Currently, for most other communication ports, sealing grooves matching the communication ports are provided on the gasket, and then a hydraulic device is used for sealing and plugging. Since the size of the gasket is fixed, if module bases of multiple different specifications are to be tested, the gasket needs to be changed separately, which is a waste of testing time and reduces the testing work efficiency.

[0004] Therefore, it is necessary to provide a new pressure testing fixture for processing module filter seats to solve the above technical problems. Content of the Utility Model

[0005] To solve the above technical problems, the utility model provides a pressure testing fixture for processing module filter seats.
