What are the reasons for the high temperature of the hydraulic oil of the metal press

　　Metal press is a kind of equipment currently used in steel mills, recycling processing industry and metal smelting industry, which can compress and pack the metal waste left over from production for storage, transportation and recycling. Most of the models of the metal press are operated by hydraulic drive, with the rise of the current temperature, the hydraulic oil temperature of the metal press is also easy to rise, once the hydraulic oil temperature rises to a certain extent, it will cause damage to various parts, which has a certain impact on the press itself and the metal scrap to be pressed. Then in addition to the external environmental problems and those reasons will cause the hydraulic oil temperature rise, this paper to carry out a simple explanation.

　　When the user finds that the hydraulic oil temperature of the metal press rises, he can first check whether it is because of poor heat dissipation, because if the dirt accumulated on the surface of the radiator is too thick, it may cause poor heat dissipation and ventilation, and the hydraulic oil temperature will rise.

　　The choice of hydraulic oil will also have an impact on this, if the selected hydraulic oil viscosity is not enough, the work of the hydraulic system will be affected, so according to the specific construction region and season, the corresponding hydraulic oil should be selected and put into use. For example, in the northern winter, a lower viscosity should be used, and a higher viscosity hydraulic oil should be used in the summer.

　　If the pressure adjustment of the system is too high during the use of the metal press, the hydraulic oil temperature will also rise, mainly because the pressure is too high, and the relief valve can not be normally relieved. Many parts of the components in the hydraulic system are actually sealed by the gap, if these components wear, then the internal leakage will cause the addition, the oil temperature will also rise.
