Description:

1) Vickers piston pump is an important device of hydraulic system. It depends on the reciprocating movement of the plunger in the cylinder, so that the volume of the sealing chamber can be changed to achieve oil absorption and oil pressure. Piston pump has many advantages, such as high rated pressure, compact structure, high efficiency and convenient flow regulation. It is widely used in occasions of high pressure, large flow and flow rate, such as hydraulic press, construction machinery and ship.

2) Wigsm Jose and plunger bushing is a pair of precision coupling parts, which can not be exchanged after paired grinding, requiring high accuracy and smoothness and good wear resistance. The radial clearance is between 0.002 and 0.003mm.

3) Wigsm Jose head cylindrical chute cut there, and through the radial hole, the axial hole and at the top of the same, the purpose is to change the cycle of oil production; plunger has put into the system, back to the hole, with the pump body cavity at the same pressure oil, pump plunger into the body suit, the application of positioning screw positioning.
