Factory For Bonded Sealing - Hydraulic oil seal – GS Seal

Characteristics of oil seal

Internal leakage refers to the leakage of oil from the high pressure chamber to the low pressure chamber. The leaked oil does not work outside, and most of its pressure can be converted into heat energy, so that the oil temperature rises, the oil viscosity decreases, and further increases the leakage, thereby reducing the volumetric efficiency of the system and the loss of power.Leakage refers to the oil leakage outside the component, which will contaminate the surrounding objects and pollute the environment. Leakage is generally not allowed.The following big orchid hydraulic manufacturers take you to understand the requirements of the hydraulic system for seals and their classification.

(1) requirements of hydraulic system for sealing of seals

① Under certain pressure, the sealing performance is reliable and the working life is long.

(2) It does not cause too much friction on the relative moving surface, and the wear is small. It can be automatically compensated after wear.

The structure is simple, easy to manufacture and disassemble.

Advantages of oil seal

1. the rubber joint has good static pressure

2. Reliable and optimized pressure-bearing design

3. Able to withstand high temperature (based on rubber material)

4. The lip of the oil return line design is better

Classification of hydraulic system seals

1.According to the different working state, the seal is divided into static seal and dynamic seal

(1) when the static seal is in normal operation, the seal between the parts with no relative movement and the surface is called the static seal.

(2) when the dynamic seal is in normal operation, the seal with the surface of the relative moving parts is called the dynamic seal.
