The Hydraulic Press uses the hydraulic system to transfer and convert energy, and most of the mechanical energy loss, pressure loss and volume loss during operation will be converted into heat to be released. The liquid in the hydraulic system will accumulate a large amount of energy from the movement of the machine during operation, and the rapid temperature of the liquid will directly affect the normal operation of the hydraulic system of the frame hydraulic press.
First, the overheating of the hydraulic fluid will increase the friction of the hydraulic system
The liquid temperature of the hydraulic press rises rapidly, which easily leads to a decrease in the straw content of the liquid and an increase in liquid leakage. The volumetric efficiency of the pump and the efficiency of the entire system will be significantly reduced. Due to the rapid decrease of the liquid straw content, the oil film of the sliding valve and other moving parts will be thinned and cut, and the frictional resistance will increase accordingly, leading to intensified wear of the machine and continuous heating.
Second, the hydraulic fluid is overheated
If the fluid temperature of the hydraulic machine is too high, it is easy to reduce the air separation pressure in the hydraulic system, and the dissolved air will easily cause cavitation in the hydraulic system, which will directly reduce the working performance of the hydraulic system.
Third, the overheating of the hydraulic fluid can easily affect the seal life of the hydraulic system
Excessively high fluid temperature of the hydraulic press will deform the rubber seals, reduce service life, premature aging failure, loss of sealing performance, and cause fluid leakage in the hydraulic system, which directly affects the normal operation of the hydraulic system.
Fourth, the overheating of the hydraulic fluid can easily cause the accuracy of the machine to decrease
Excessive fluid temperature of hydraulic press will cause thermal deformation of the machine, which will make the gap between moving parts with different thermal expansion coefficients in hydraulic components become smaller and become stuck, causing malfunctions, which directly affects the accuracy of hydraulic equipment and the quality of products produced.
