The parts should be designed with a guide Angle to avoid damage to the seals during assembly. When the sealing ring is assembled in the part with sharp edge and groove, the protective sleeve should be used to avoid damage to the seal. The hydraulic line should be set so that the distance between the tank and the actuator is as short as possible to reduce pressure loss and friction. In the hydraulic system, the pipe joint should be reduced as far as possible, and 30% to 40% of the system oil leakage is from the pipe joint.
The oil temperature is too high, the lubricating oil film is thinner, the friction is increased, the wear is increased, the sealing material is aging faster, making it hard and brittle, and may soon lead to leakage. The control of the temperature rise of the hydraulic system is generally started from the design of the fuel tank and the setting of the hydraulic pipeline.
Choosing the right hydraulic components and fittings is very important. The selection of hydraulic components in the previous promotion we have talked about, here is no longer elaborated, the hydraulic system commonly used pipe joints have flaring type, sleeve type and welding type three types. These three joints have their own characteristics and should be selected according to working reliability and economy.
