Fault Analysis And Troubleshooting Method Of Oil Tank Of Hydraulic Press

1. The temperature of the hydraulic oil tank has risen seriously
The hydraulic oil tank acts as a thermal flywheel, which can absorb heat in a short period of time, and can also prevent the hydraulic system from being over-cooled during short-term idling in a cold environment. However, the main problem of the oil tank is the temperature rise. Severe temperature rises can cause multiple failures in hydraulic systems.
1) Reasons for the excessive temperature rise of the hydraulic oil tank:
The hydraulic oil tank is set near the high-temperature radiation source, and the ambient temperature rises. All kinds of pressure loss in the hydraulic system will be converted into heat and cause the temperature of the oil to rise. The heat dissipation area of the fuel tank design is not enough.
2) The solution to the temperature rise of the hydraulic oil tank:
Try to avoid heat sources, but the use of plastic machinery must have heat sources. Correctly design the oil system to reduce various pressure losses and reduce heat rise. Correctly select hydraulic components, strive to improve the machining accuracy and assembly accuracy of hydraulic components, and reduce the heat increase caused by leakage losses and mechanical losses.
2. Oxidation and deterioration of the oil in the hydraulic oil tank
The oxidative deterioration of the oil in the hydraulic oil tank is related to the type of oil, operating temperature, rest time and the presence of oxidation catalysts. To choose the type of oil, you need to choose the oil type and viscosity that meet the performance according to the working conditions and working environment.
3. Oil pollution in the hydraulic oil tank
The oil pollutants in the hydraulic oil tank are invaded from the outside, produced internally, and produced during assembly. In order to prevent pollutants from the outside invading the oil tank from being sucked into the pump, a partition should be installed in the oil tank to separate the oil return area and the oil suction area.
4. It is difficult to separate the oil and air bubbles in the hydraulic oil tank
Due to the stirring effect of the returned oil in the oil tank, it is easy to generate suspended air bubbles trapped in the oil, and if they are brought into the oil system, many failures will occur. In order to prevent oil bubbles from being sucked into the pump before they are eliminated, partitions and metal meshes can be installed.
