Daikin Hydraulic Piston Pump VZ series FAQS

QHow does a piston hydraulic pump work?

APiston pumps and plunger pumps use a mechanism (typically rotational) to create a reciprocating motion along an axis, which then builds pressure in a cylinder or working barrel to force gas or fluid through the pump. The pressure in the chamber actuates the valves at both the suction and discharge points.

QWhat is gear type pump?

AA gear pump uses the meshing of gears to pump fluid by displacement. They are one of the most common types of pumps for hydraulic fluid power applications. ... Gear pumps are also widely used in chemical installations to pump high viscosity fluids.

QWhat is the difference between gear pump and vane pump?

AGear and vane pumps typically do not have separate case drains. ... Axial variable-flow piston pumps are recommended for handling flow or pressure changes in a hydraulic system. These pumps offer higher efficiencies in power use. Fluid is pumped as the cylinder block rotates and the pistons bear against a cam.

QWhat is oil pumping?

AA pump jack is a device used in the petroleum industry to extract crude oil from a oil well where there is not high enough pressure in the well to force the oil to the surface.
