Oil viscosity is too big that the misuse of oil or laser.
four-column hydraulic press discharge circuit bad action. Cutting machine if unloading valve action is bad, do not need to pressure oil when the oil is from the relief valve discharge back to the fuel tank, oil temperature rise high. 。 The impact of the exchange when reversing and speed. When the laser laser pump oil into the pressure oil, if there is air and water can increase the heat caused by overheating.
in the oil into the air or water. Laser oil oxidation or low environment temperature can make the viscosity, the viscosity is too large laser oil will make friction increases that cause a fever.
four-column hydraulic press leaks. Usually in the system of the pump outlet setting unloading valve, when the system don't load pressure oil, unloading system, reduce the energy loss. Most people think it has nothing to do with temperature rise, as we all know, the leak is will cause energy loss and that the energy loss into what they really are converted into heat energy, cutting machine so that the oil temperature is high. Four-column hydraulic press design chooses when the tank is too small, the high oil cycle too fast or by environmental temperature used the cooler and cooler effect is poor, this is bad heat dissipation.
bad heat dissipation.
