The influence of temperature factor on the performance of hydraulic cylinder is discussed

The temperature has a corresponding effect on the performance of the hydraulic cylinder. In general, the working temperature of the cylinder block is usually between -10 and 80 ° C, and does not exceed the limit of -20 to 105 ° C. Too high or too low temperature will adversely affect the performance of the hydraulic cylinder.

Working at high temperatures, the seal of the cylinder block should be fluorinated rubber, which can work at + 200-250 ℃ high temperature for a long time, and the durability is obviously better. However, the expansion coefficient of various materials is different, so the sliding surface size should be properly trimmed. For example, the expansion coefficient of steel is 10.6X10, while the expansion coefficient of oil-resistant rubber is 10-20 times that of steel. For hydraulic cylinders working at high temperatures, the sliding surface size should be appropriately trimmed because of the different expansion coefficients of various materials.

In addition, the working temperature of the cylinder block is limited by the working performance of the seal. Because the hydraulic press mostly uses butadiene rubber as a seal, its working temperature can not exceed the working temperature range of butadiene rubber, so the working temperature of the cylinder block is limited by the working performance of the seal.

Therefore, when designing and using the hydraulic cylinder, it is necessary to consider the influence of temperature factors to ensure its normal work and extend its service life.
