As for the direction control, it mainly depends on the directional valve or logic control unit. For the hydraulic pump station system with medium and small flow, most of the required actions are completed through the organic combination of directional valves.

For the hydraulic system with high pressure and large flow rate, the connection between the two is often used -- volume saving speed regulation. Volume speed regulation is intended to achieve speed regulation by changing the displacement of hydraulic pump. The utility model has the advantages of no overflow loss and saving loss, and high power.

However, in order to dissipate heat and supplement leakage, an auxiliary pump is required. This conditioning mode is applicable to the hydraulic pump station system with large power and high movement speed. These two control systems occupy the center of the hydraulic pump station. Failure of either party to control properly may lead to problems of the hydraulic pump station. Therefore, the perfect relationship between the two is the basis for ensuring the normal operation of the hydraulic pump station.

The hydraulic pump station is the main component of the hydraulic system, and it is also a part of the hydraulic operation. What is the central problem of hydraulic pump station? In fact, as far as the hydraulic pump station is concerned, Z's first priority is the direction and speed of movement, which is also the central issue of the hydraulic pump station.
