Hydraulic cylinder Delivery of sealed fluid volume changes to inform energy and speed. The sealing device will directly affect the working performance of the hydraulic cylinder. The hydraulic cylinder with poor sealing will not only pollute, lower the volume, comply with the order, increase the power loss, but also affect the normal operation of the hydraulic cylinder unintentionally. It is impossible to seal correctly. When the piston rod moves back and forth, it always brings out oil. However, such leakage should be small. Similarly, if the reciprocating motion of the piston rod does not bring out any oil, the piston rod will be in dry resistance, which will affect the working performance and life of the hydraulic cylinder.

When planning the sealing device, it is necessary to control the use field of the hydraulic cylinder, the application pressure, the flow speed, the task environment, the performance of the working oil and additives, the material, shape, use, reasoning power, agreed leakage amount of the seals, the processing accuracy and smoothness of the battle surface, etc., so as to select the seals correctly and reasonably and manage the sealing device.

The materials used for the seals of hydraulic cylinders must have the performance of oil resistance, abrasion resistance, heat resistance, cold resistance, chemical resistance, and certain resilience and compressive strength.

If the sealing device is not properly managed, the seal will be squeezed, twisted or even broken under the influence of hydraulic pressure, resulting in oil leakage. Perhaps the debris of the seal is stuck in the gap, making the hydraulic rainbow unable to move abnormally. In order to prevent the occurrence of such signs, it is necessary to determine the fit clearance between the two sealing surfaces according to the appropriate pressure, accurately determine the hardness of the sealing material, and use the protective retaining ring when required.
