Do you know what are the impact pressure forms of hydraulic stations?

During the use of the hydraulic station, the hydraulic pump should be started several times when it is started. After the oil flow direction and sound are normal, run it at low pressure for 5-10 minutes, and then put it into normal operation. Before starting the plunger pump, it is necessary to fill the pump with clean working oil through the drain port on the shell.

The viscosity of the oil changes under the influence of temperature. As the oil temperature rises, the viscosity decreases. Therefore, the oil temperature must be kept below 60℃. In order to make the hydraulic pump work stably at different working temperatures, the selected oil should have viscosity Oil temperature characteristics that are less affected by temperature changes, as well as better chemical stability and anti-foam performance.

　　 The oil used in the hydraulic station must be kept clean and not 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 the oil filter truck. The normal working oil temperature is 15～65℃. The high temperature on the pump casing is generally 10～20℃ higher than the oil temperature at the pump inlet in the fuel tank. When the oil temperature in the fuel tank reaches 65℃, the high temperature on the pump casing is not higher than 75～85℃.

There are two forms of impact pressure in hydraulic stations. One is the impact pressure generated in the hydraulic system when opening or closing the fluid flow path; the other is when the movement speed of the hydraulic cylinder is changed due to the inertia of the liquid and the movement mechanism. And the pressure shock caused.

　　The pressure shock is caused by the change of the pipe liquid flow velocity. For example, the hydraulic actuator will suddenly stop during movement, and the opening and closing of the reversing valve will generate an impact pressure higher than the static value. Not only will it be accompanied by vibration and noise, but also the pipeline and hydraulic components will be damaged due to excessive impact pressure.
