What happens to 12 tons of crane hydraulic overheating
The crane is relatively flexible to operate and will be used in many construction projects. It also brings a lot of convenience to the construction. What happens if the hydraulic pressure of a 12-ton crane is too hot?
1. The 12-ton crane is thermally deformed, and moving parts with different thermal expansion coefficients in the hydraulic components are jammed due to their smaller clearances, causing malfunctions and affecting the transmission of the hydraulic system, resulting in poor working quality of the components.
2. Accelerate the oxidative deterioration of the oil, and precipitate the asphalt material to reduce the service life of the hydraulic oil.
3. Reduce the viscosity of the oil, increase the leakage, 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 moving parts such as slide valves becomes thinner and is cut, increasing frictional resistance, resulting in increased wear.
4. Distorting the rubber seals of the 12-ton crane, accelerating aging and failure, reducing sealing performance and service life, causing leakage. Editor: A
