What are the hazards of heating in the hydraulic system of stainless steel gear pumps?

The heating of the stainless steel gear pump hydraulic system directly affects the normal operation of the stainless steel gear pump. The hazards caused by the heating phenomenon mainly include the following points:
(1) 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.
(2) The seals of hydraulic systems and components deteriorate at high temperatures, reducing their elastic deformation ability, resulting in decreased sealing performance and even seal failure, leading to increased leakage.
(3) When the valve core and valve body materials of hydraulic valve components are different and the thermal expansion coefficient is different, the valve core and valve body may become stuck due to thermal expansion, causing the stainless steel gear pump to not work.
(4) When the viscosity of the working fluid decreases, the lubrication performance of the working fluid decreases, the wear of hydraulic components accelerates, the wear and failure of components is accelerated, and the service life of components is shortened.
In order to avoid the occurrence of the above phenomenon as much as possible, some stainless steel gear pumps have to be stopped after a certain period of use to cool down the system, thereby reducing the start-up rate of the stainless steel gear pump and affecting the construction progress. Therefore, corresponding measures should be taken to address the causes of system heating, control the temperature of the hydraulic system, and ensure the normal use of the stainless steel gear pump.
