How the hydraulic pump works

How the hydraulic pump works

1.At present, the hydraulic pump used in the hydraulic system has almost the same working principle, that is, the hydraulically sealed working chamber volume change rate realizes oil absorption and oil pressure, so it is called a volumetric hydraulic pump.

2.The working principle of the positive displacement hydraulic pump is very simple. Take the single-piston hydraulic pump as an example. Just like our common medical syringe, it can be equipped with an automatic assembly flow device.

●There is a change in the tight seal volume

The sealing volume is increased from small to large; the oil is changed from large to small.

●Distribution mechanism

When the sealing volume is ensured to be small, it is only connected to the suction pipe; otherwise, it is only the same as the pressure pipe.
