Plane sealing performance testing device

Abstract

The invention provides a plane sealing performance testing device which comprises a casing with an opening. A fixed face, a cylinder and a first piston are arranged in the casing, the fixed face is fixedly connected in a sealing mode along the section of the casing, the first piston is fixedly connected with a second piston in the cylinder through a connection rod, the space formed between the fixed face and the first piston forms a liquid storage cavity used for storing liquid, and a hole for liquid in the liquid storage cavity to flow in and out is formed in the fixed face. The plane sealing performance testing device is simple in structure, convenient to operate, capable of effectively testing the sealing performance of a plane sealing piece and further obtaining a series of sealing data with long-term guide value, effectively improves sealing design accuracy, reduces leakage and reduces dependency on professional sealing designers.

Description

technical field [0001] The invention relates to the technical field of sealing test, in particular to a plane sealing test device. Background technique [0002] Seal testing is an important measure to ensure the reliable performance of the connection plane. Any plane contact connection surface needs to be tested for leak tightness, especially for equipment with high technical requirements, which requires high-demand leak test. The airtightness of the workpiece is related to the running performance of the whole machine, so the airtightness detection of the workpiece is particularly important. For the plane contact connection structure with strict requirements, the airtightness of the plane needs to be tested before assembly, and the untested plane is assembled according to the normal assembly process before the airtightness problem is detected, which causes a waste of resources. [0003] The airtightness of the workpiece is related to the running performance of the whole mac...

AI Technical Summary

Problems solved by technology

The air tightness test must be carried out in strict accordance with the decompression procedure. Every machinery factory has its own unique air tightness test method. quality, and the traditional workpiece airtight detection device is cumbersome and difficult to operate, wasting a lot of time and manpower and material resources

However, few of the existing sealing testing equipment are dedicated to flat sealing testing, and most of them are complex in structure and high in cost. The call of carbon economy, to increase the economic benefits of enterprises, needs to develop new sealing test equipment
