The direction of the oil circuit when the power unit is working

The hydraulic pump is the power component of the hydraulic system to supply pressure oil for the entire system. The pressure oil from the outlet of the hydraulic pump directly reaches the oil inlet of the control valve through the oil pipe. Of course, there is generally a filter screen on the oil tank. movement.

Control the hydraulic power unit: The hydraulic pressure of the integrated block can realize the adjustment of pressure, flow, and direction, and then transfer it to the cylinder or motor by an external connection, so as to control the rolling direction of the hydraulic power unit, the size of the strength, the speed of the speed, and the propulsion of the hydraulic machine. Do mechanical work. The structure of the hydraulic station is firstly differentiated according to the structure of the pump equipment, the direction of the equipment and the method of cooling.

After the hydraulic oil is dissolved and used, there may be impurities or degeneration inside the hydraulic oil. Take samples and collect and check to see if it contains fluid particles, discoloration, and odor. The hydraulic oil must be converted when required. The hydraulic pump is also a key factor affecting the flow of hydraulic oil. After the hydraulic pump is used for a long time, it will easily cause wear. When the path speed of the hydraulic elevator slows down, check whether the oil supply flow of the hydraulic pump remains unchanged.

When selecting the absolute filter of the hydraulic station, its accuracy should be determined by considering the oil pollution that the key components in the system can withstand, the interference intrusion rate of the system and the working conditions, etc., start from the pollution damage control point and filter The accuracy of the device should be able to ensure that the standard particles close to the dynamic oil film thickness of the component motion pair are effectively filtered out, because once this standard lining particle enters the vacancy of the motion pair, it will cause the surface of the component to wear and increase the vacancy. Standard conductive particles enter the vacancy and cause the failure of the component.
