The Precision Welded Pipe Machine Will Generate Heat After Prolonged Use

It is a common phenomenon that welded pipes will heat up after a long time, but it will affect the normal operation of concrete pumps. So, what are the effects of prolonged heating of welded pipes?

It is a common phenomenon that welded pipes will heat up after a long time, but it will affect the normal operation of concrete pumps. So, what are the effects of prolonged heating of welded pipes?

a. The sealing parts of welded pipes and components deteriorate at high temperatures, reducing their elastic deformation ability, resulting in decreased sealing performance, and even sealing failure, leading to increased leakage;

b. When the materials of the valve core and valve body of the hydraulic valve are different and the thermal expansion coefficient is different, the valve core and valve body may become stuck due to thermal expansion, resulting in the inability of the concrete pump to work;

c. After the temperature of the working fluid increases, the viscosity of the working fluid decreases, the leakage of the pump increases, and the actual flow rate of the pump decreases;

d. When the viscosity of the working fluid decreases, the lubrication performance of the working fluid decreases, and the wear of hydraulic components accelerates, which accelerates the wear of components and shortens their service life.

In order to avoid the occurrence of the above phenomenon as much as possible, some concrete pumps need to be stopped after a certain period of use to cool down the system and ensure the normal use of the concrete pump.
