Causes of high-temperature clamping cylinder and ordinary cylinder failure:
Disassembly and inspection of failed cylinders found that the main failure of most cylinders was the failure of sealing rings, gluing or lip wear. It was judged that the operating temperature was too high and caused the sealing ring to fail.
The difference between high-temperature clamping cylinder and ordinary cylinder:
1.Selection of sealing rings
After we choose the correct sealing ring, the working life of the cylinder is improved, and the effect is obvious. The following content is organized according to the characteristics and applicable temperature of the sealing ring:
Nitrile rubber: wear-resistant, heat-resistant, wear-resistant, corrosion-resistant, applicable temperature: -30-100°C, widely used in hydraulic and pneumatic systems. Sealing and static sealing.
Fluorine rubber: excellent in high temperature resistance, oil resistance, vacuum resistance, and resistance to various chemicals;poor low temperature characteristics, large compression deformation, high price, low mechanical strength, and poor processability . Applicable temperature: -30℃-200℃, suitable for sealing high temperature and special media.
2.RunSelection of lubricating oil
The lubricating oil of ordinary cylinders will automatically soften at high temperatures, causing the cylinder to not operate normally. Therefore, high-temperature-resistant cylinders generally use high-temperature-resistant lubricating oil to maintain the solidity of the lubricating oil in high-temperature environments. state, reduce friction, prolonggasCylinderOperating life.
High-temperature finger cylinder applicable environment: different from ordinary finger cylinders, high-temperature resistant clamping cylinders can be used in high-temperature environments in heating furnace-related equipment, electrolytic cell-related equipment, chemical industry and other related fields Down.
