Harm of overheating of XCMG crane parts
1. If the temperature of XCMG crane parts is too high, the equipment will be deformed, and the gaps in the components will become smaller due to different thermal expansion coefficients, which will cause the action to fail, affect the transmission accuracy of the hydraulic system, and cause the working quality of the components to deteriorate.
2. The viscosity of the oil is reduced, resulting in an increase in leakage, and the volumetric efficiency of the pump and the efficiency of the entire system will be significantly reduced. As the viscosity of the oil decreases, the oil film of the moving parts such as the spool valve becomes thinner and cut off, and the frictional resistance increases, resulting in increased wear.
3. The deformation of the rubber seal will accelerate the aging failure, reduce the sealing performance and service life, and cause leakage. XCMG crane accessories.
4. Make the oxidation rate of oil faster, precipitate to form asphalt, and reduce the service life of hydraulic oil. The sediment blocks the damping holes and the clearance valve ports, causing the pressure valve to be stuck and unable to move, and the metal pipes are stretched and bent, or even cracked.
5. XCMG crane accessories reduce the air separation pressure of the oil, and the air dissolved in the oil escapes, which reduces the working performance of the hydraulic system.
