Description

Technical Field

[0001] This utility model relates to the field of pneumatic transmission technology, specifically to a leak-proof sealing structure for pneumatic power mechanical components. Background Technology

[0002] Pneumatic technology, also known as pneumatic transmission and control technology, is an engineering technology that uses compressed air as a power source to transmit energy and information. Simply put, it involves controlling the movement of various mechanical devices using compressed air.

[0003] A cylinder is a cylindrical metal component that guides a piston in linear reciprocating motion within the cylinder. In an engine cylinder, air expands, converting thermal energy into mechanical energy; in a compressor cylinder, gas is compressed by the piston, increasing its pressure. The sealing performance of the cylinder is crucial for its proper functioning. Cylinder leakage is a common malfunction in reciprocating machinery (such as engines and compressors). Leakage locations vary, depending primarily on the cylinder's structure and usage. Common leakage points are the cylinder's inlet and outlet ports. Over time, these ports can be subjected to pressure shocks or wear and deformation due to improper installation during maintenance, leading to leakage, pressure drop, and unstable or even malfunctioning cylinder movement. Therefore, we have designed a leak-proof sealing structure for pneumatic power mechanical components to prevent leakage at their inlet and outlet ports. Utility Model Content
