Description of double vane pump

Double vane pump is composed of two single-stage vane pump installed in a pump body in parallel on the oil circuit. The rotors of the two vane pumps are driven by the same drive shaft and have independent oil outlet. The two pumps may have equal flow or unequal flow [1].

Application

Double vane pump is often used for the rapid feed and work feed requirements of the mechanical processing of the special machine tool, when the double pump by a small flow and a large flow pump composition. When fast feed, the two pumps supply oil at the same time (at this time the pressure is low), when the work feed, by the small flow pump supply oil (at this time the pressure is high), at the same time in the oil system to make the large flow pump unloading, compared with the use of a high pressure pump, can save energy, reduce oil heating. This double vane pump is also often used in the hydraulic system of machine tools need two independent oil circuit.
