How to use the hydraulic pump correctly
The hydraulic pump is an indispensable device for the hydraulic system. In order to ensure that the hydraulic pump can be used for a long time without failure, I will teach you how to use the hydraulic pump correctly.
1.When the hydraulic pump is started, it should be jogged several times first. After the oil flow direction and sound are normal, it should be operated under low pressure for 5 to 10 minutes, and then put into normal operation. Before the piston pump is started, the pump must be filled with clean working oil through the oil drain port on the casing.
2.The viscosity of the oil is affected by the temperature, and the viscosity of the oil decreases with the increase of the temperature, so the oil temperature is required to be kept below 60°C. In order to make the hydraulic pump work stably at different working temperatures, the selected oil should have The viscosity is less affected by temperature changes, oil temperature characteristics, and better chemical stability, anti-foaming performance, etc.
3.The oil must be clean and must not be mixed with mechanical impurities and corrosive substances. The hydraulic system without a filter device on the oil suction line must be refueled to the oil tank through an oil filter vehicle (filter accuracy less than 25 μm).
4.The maximum pressure and maximum speed of the hydraulic pump refer to the peak value allowed in a short period of time during use, and long-term use should be avoided, otherwise the life of the hydraulic pump will be affected.
5.The normal working oil temperature of the hydraulic pump is 15-65°C. The highest temperature on the pump casing is generally 10-20°C higher than the oil temperature at the pump inlet in the fuel tank. When the oil temperature in the fuel tank reaches 65°C, the highest temperature on the pump casing The temperature should not exceed 75-85°C.
