What should be paid attention to in hydraulic wrench hydraulic oil

What should be paid attention to in hydraulic wrench hydraulic oil
1. Keep the hydraulic oil clean and prevent impurities such as metal chips and fibers from entering the oil.
2. The oil tank should be thoroughly cleaned before adding oil, and the new oil must be filtered (the accuracy of the filter is generally 5-10μm), otherwise the performance of the hydraulic system and the life of the hydraulic pump will be greatly affected .
3. Regularly check the oil quality and oil level.
4. It should be ensured that the temperature rise of the oil in the oil tank does not exceed the allowable range of the hydraulic oil, and all work generally requires not to exceed 60°C, otherwise the cooling system of the hydraulic oil needs to be checked. When the oil temperature is too low, the oil should be preheated so that the oil temperature gradually rises (requires a temperature of more than 30°C) before running the machine.
5. The best temperature of the hydraulic system oil temperature is between 35～55℃. Once the temperature rises above 60℃, the performance of the hydraulic system will be greatly reduced, hydraulic equipment failures will continue to appear, the ideal working oil temperature of the hydraulic system It is between 45 and 50 degrees. The reason is that the hydraulic system is designed according to a selected pressure oil viscosity, but the viscosity will change with the oil temperature, which will affect the working components in the system, such as cylinders and hydraulic valves. Reduce the control accuracy and response sensitivity. At the same time, too high a temperature will accelerate the aging of the seal, causing it to harden and crack. Therefore, it is necessary to pay close attention to the working temperature of hydraulic oil.
6. According to the hydraulic pump outlet pressure and oil temperature, select varieties:
HL for pressure lower than 7.0MPa:
For pressure from 7.0 to 14.0MPa, HL or HM is used for oil temperature below 50 degrees Celsius, and HM is used for oil temperature above 50 degrees Celsius to 80.
The pressure is greater than 14.0MPa, and the oil temperature is 50 to 80 degrees Celsius with HM.
The new hydraulic pump uses No. 32 and No. 46 hydraulic oil, and the old pump uses No. 46 and No. 68 and above. If the pressure is greater than 30.0MPa, the higher level 1-2 should be selected accordingly.
