PTFE reducer oil seals are mainly used in air compressors, reducers, engines, gearboxes, motors, vacuum pumps, high-temperature hot oil pumps, air conditioners, mixers, automated precision machinery, chemical processing equipment, pharmaceuticals and food processing Equipment, etc., especially suitable for applications that traditional rubber oil seals cannot meet.
It has the following advantages: 1. The rubber oil seal adopts a spring-pressed sharp lip, and the contact surface with the shaft is only 0.3-0.5mm wide. The PTFE oil seal adopts a spring-free wide-lip dynamic structure, which contacts the shaft. The surface width is 5-7mm, which can maintain a sufficient oil film and is not sensitive to the eccentricity of the shaft. It can still work normally under the condition of radial runout of 0.4mm. 2. The PTFE oil seal can seal the fluid pressure of 1.0MPa (single lip) and 3MPa (double lip), while the rubber oil seal is only 0.03MPa?
3. The PTFE oil seal has excellent friction resistance and is particularly suitable for use. Working in an oil-free or low-oil state, even if it is restarted after a long shutdown, it can immediately have low friction characteristics. 4. PTFE oil seal is particularly suitable for high-speed rotation applications, with speeds up to 30m/s? 5. PTFE oil seal can seal water, acids, alkalis, solvents, gas, high-viscosity fluids, etc.
6. The operating temperature of PTFE oil seal is -100-+350℃, and the operating temperature of fluororubber vacuum pump oil seal is -40-200℃
