The hydraulic oil of the normal temperature hydraulic metal baler should be controlled within 60 degree C in the coming summer, and the temperature of the hydraulic metal baler of the hydraulic oil will rise with the gradual rise in temperature. When reaching more than 80 degrees, because of the different coefficient of thermal expansion, the relative gap and the motion state between the operating components of the hydraulic element will emit abnormal changes in oil temperature. When the oil temperature exceeds 60 degrees, the viscosity of the oil will decrease, the leakage amount will increase, and the sliding part of the oil film will be destroyed, thus increasing the wear of the hydraulic components, thereby accelerating the speed of temperature rise.

1 The heat dissipation of the metal baler is poor

2 Hydraulic oil selection

3 The pressure of the metal baler is improperly adjusted

4 Hydraulic pump suction

5 Component Wear

6 Leaks


1, strengthen the regular inspection of hydraulic components, motors and pumps, such as being found damaged to replace immediately, good motor and oil pump, can effectively reduce the temperature of hydraulic oil.
2, properly reduce the working pressure of the hydraulic station system, avoid overload of the equipment system with excessive pressure, so that the pump and valve group of hydraulic oil can effectively reduce friction and reduce temperature.
3, increase the hydraulic oil cooler air cooling and water cooling, these two heat dissipation devices are added to the metal baler tank, can effectively reduce the high temperature of hydraulic oil.
