How to do when the metal baler rises in temperature during use?

 Normal temperature metal baler hydraulic oil should be controlled within 60°C in the summer. With the gradually rising temperature, the temperature of the metal baler hydraulic oil will increase. When reaching 80 degrees or more because of different thermal expansion coefficients, the relative difference between the components and the running state of the hydraulic components will give rise to abnormal changes in oil temperature. When the oil temperature exceeds 60 degrees, the viscosity of the oil will decrease, the amount of leakage increases, and the sliding part of the oil film will be destroyed, thereby increasing the wear of the hydraulic components, thereby accelerating the temperature rise. Large gaps increase oil leakage; gaps become smaller and may occur as a component of the phenomenon that it is impossible to exercise the machine, resulting in the loss of will, the destruction of the original precision thermal distortion between the "death" phenomenon.

 

The temperature of the rising hydraulic oil is affected not only by the surrounding environment but also by other factors. It is found that when the oil temperature of the hydraulic machine rises, the customer can find out the following reasons:

 

1, metal baler poor heat dissipation
     Excessive fouling of the surface of the heat sink can lead to heat generation and poor ventilation, resulting in excessive oil temperature in the hydraulic tank; systems with too low a liquid level and circulating oil are not enough and will lead to high temperatures in the system.

2, hydraulic oil pump
      The improper selection of hydraulic oil brands, especially the viscosity index oil, will directly threaten the normal operation of the hydraulic system. Hydraulic oil viscosity range and viscosity change characteristics as small as possible, so the choice of hydraulic oil should also be considered in a specific region and season; there is a clear definition of the oil mark machine should be filled in accordance with the provisions of the hydraulic oil filling .

3, improper adjustment of the metal baler pressure
     The system pressure relief valve is adjusted too high to perform normal spillage and pressure reduction, resulting in increased internal leakage and temperature rise.

4、Air pump suction air shield protection equipment
     The suction of air from the hydraulic pump and the air in the oil mix too much, creating "cavitation", and under high hydraulic pressure, accompanied by strong vibration and noise, resulting in rapid temperature rise.

5, component wear
      Severe wear on hydraulic system components can cause the system to overheat. Many parts of the system's components rely on seal gaps. Once the hydraulic components wear, this will cause an increase in the amount of internal leakage, which will cause the temperature to rise and the viscosity of the oil to decrease. Finally, the internal leakage will increase further, resulting in oil temperature. To further improve and form a vicious circle.

6, leak
      In the process of energy transfer, if the leakage is serious, the volume loss of the system will increase, and the loss of energy will be converted into the high-temperature thermal energy of the induced system. If the element space is too small, the friction between the relative movements can also increase the temperature of the oil; and the gap is too large to cause serious leakage.


      The temperature is too high to find the cause, and then the hydraulic fluid of the metal baler can be purposely cooled. You can take the following measures:
      1. Strengthen the regular inspection of hydraulic components, motors and pumps. If it is found to be damaged, replace it immediately. A good motor and oil pump can effectively reduce the temperature of hydraulic oil.
      2, properly reduce the working pressure of the hydraulic station system, to avoid over-pressure equipment system overload, making the pump and valve group through the hydraulic oil can effectively reduce the friction and reduce the temperature.
      3, increase the hydraulic oil cooler air cooling and water cooling, the two heat sinks are added to the metal baler oil tank, can effectively reduce the hydraulic oil high temperature.
