Pump trucks play a non-negligible role in the construction of infrastructure, especially in construction machinery and other industries, which often use pump trucks. In order to ensure the safe and normal operation, the phenomenon of heating of the hydraulic system should be avoided in the process of use, because the harm is relatively large.
1. After heating and temperature rise, the seals of the hydraulic system and its components are very prone to deterioration, which will lead to poor elasticity, low sealing, and severe seal failure, increasing the risk of leakage;
2. After the hydraulic system of the pump car heats up, the viscosity of the working liquid will decrease, and the lubrication performance will also be reduced, which will accelerate the wear of the hydraulic components and greatly shorten the service life of the components.
3, after the temperature of the working liquid rises, the viscosity of the working liquid decreases, the leakage of the pump increases, and the actual flow of the pump will become decreased;
4, the hydraulic valve spool and valve body material is different, the coefficient of thermal expansion will be different, between the valve spool and the valve body due to thermal expansion caused by the phenomenon of spool stuck, resulting in the concrete pump can not work normally.
Qingdao Hetaifeng Co., Ltd. reminds that in the daily use of the pump truck, do not operate for too long, and regularly cool it down. Different heating causes should take different relevant measures to ensure the service life of the pump.
