The main reason of oil temperature rise of four column hydraulic press

The main reason of oil temperature rise of four column hydraulic press?

Four column oil pressure oil temperature should be appropriate. The oil temperature of the tank should not exceed 60℃, and it is suitable to work within the range of 35 ~ 55℃. From the point of view of maintenance, also should absolutely avoid high oil temperature. If the oil temperature has abnormal rise, should be checked.

Common reasons are as follows:

1. The viscosity of oil is too high.

2. Oil quality deteriorates and resistance increases.

3. The performance of the cooler is not good, such as insufficient water, scale in the pipeline, etc.

4. The air in the loop should be completely removed. Loop into the air, because the volume of the gas and the pressure is inversely proportional, so with the change of load, the movement of the hydraulic cylinder should also be affected, so should especially avoid air mixing). In addition, air is an important cause of oil deterioration and heating.

The following matters should be paid special attention to the oil temperature rise of the four-column oil press:

① After the inlet filter is blocked, the suction resistance is greatly increased, and the air dissolved in the oil is separated, resulting in the so-called cavitation phenomenon;

(2) Suction pipe and pump shaft sealing part of each lower than atmospheric pressure should pay attention to not leak into the air;

When the four-column hydraulic press starts the hydraulic pump for the first time or does not operate for a long time, the following matters should be paid attention to:

(1) Fill the pump with working medium;

② Check whether the direction of rotation is correct;

When the four-column hydraulic press starts the hydraulic pump at low temperature, the following matters should be paid attention to:

When starting the hydraulic pump in the cold zone or winter, it should start and stop, reciprocate several times to make the oil temperature rise, and then enter the formal operation after the hydraulic device is operated flexibly.
