Concrete Pump Pipe will heat up, which will directly affect the normal work of concrete pump and the damage caused by heat. The main points are as follows:
1.Concrete Pump Pipe and component seals deteriorate at high temperatures, and the elastic denaturing ability is reduced, resulting in reduced sealing performance and even seal failure, resulting in increased leakage;
2. When the valve body and valve body material of the hydraulic valve member are different and the thermal expansion coefficient is different, the valve core is stuck due to thermal expansion between the valve core and the valve body, so that the concrete pump cannot work;
3. After the temperature of the working liquid rises, the viscosity of the working liquid is lowered, the leakage of the pump is increased, and the actual flow rate of the Concrete Pump Pipe is decreased;
4. When the viscosity of the working liquid is lowered, the lubricating performance of the working liquid is lowered, the wear of the hydraulic component is accelerated, the wear failure of the component is accelerated, and the service life of the component is shortened.
In order to avoid the above phenomenon as much as possible, some concrete pumps have to stop after a certain period of use to cool the system, thereby reducing the operating rate of the concrete pump and affecting the construction progress. Therefore, measures should be taken for the cause of system heating, and the wear-resistant tube controls the temperature of the Concrete Pump Pipe to ensure the normal use of the concrete pump.
