Why is the oil temperature of a universal artificial board test machine too high

Cause artificial boardUniversal testing machineThere may be four reasons for excessive oil temperature during operation:
,Universal test machine for artificial boardThe selection of hydraulic component specifications in hydraulic systems is unreasonable. When choosing a valve, the energy loss is too large due to the small specifications, which causes the system to overheat; or the flow rate in the valve is too high, causing noise. When using a pump, the flow rate of the pump is large, and excess oil overflows from the overflow valve, causing the oil temperature to overheat.
Second, there are excess hydraulic circuits or excess hydraulic components in the hydraulic system of the artificial board universal test machine.
Third, in the hydraulic system of the artificial board universal test machine, the structural design of the hydraulic components is unreasonable and the manufacturing quality is poor. After the oil flows through the valve, the pressure loss is large and the internal leakage is serious.
Fourth, during non-working processes, the hydraulic system does not have effective unloading measures, which causes a large amount of pressure oil to be lost and the oil is heated.
Fifth, the throttling adjustment method is inappropriate.
