When it comes to rotary vane pumps, there are utilized in a variety of industries be it large or small scale manufacturers, craftsmen and individual designers. Their primary usage is fixated to the production as well as handling of materials at different formation stages of raw materials and further ranging till the management and packaging of end products.
To be precise, rotary vane pumps are basically oil-sealed rotary displacement pump; however, they can even function as dry pumps as well. These rotary pumps are designed in both single- and two-stage varieties. Characteristically, a two-stage pump would attain lower pressures as compared to a single-stage pump.
Functionality of Rotary Vane Pumps
In common, the basic design for a rotary vane vacuum system comprises of the installed rotor, pump housing, vanes which converge at a common center along with an inlet and outlet. Furthermore, the housing includes two openings; the oil-sealed outlet valve and the inlet valve that is designed for vacuum safety. It is important to know that the vacuum safety valve stays open throughout the operation.
Furthermore, the rotor and the vanes tend to split the working chamber into two separate spaces which hold variable volumes. Once the rotor turns, the trapped gas transfers into a suction chamber by the time it is sealed off via the second vane. Later on, the enclosed gas gets compressed by the time outlet valve opens associated with atmospheric pressure.
Applications of Rotary Vane Pumps
Talking about the applications of rotary vane pumps, the most common usage is associated to high-pressure hydraulic pumps used in automobiles, such as supercharging, air conditioning, automatic-transmission pumps and power-steering. On the other hand, pumps for mid-range pressures cover applications such as espresso coffee machines. With such interesting uses, the rotary pumps market is blolstering at an imperative speed.
