The power of pumps is indispensable to a number of industries with different pumps being available to get the jobs done in varied industrial settings. One of them is the rotary vane pump which functions on the principle of positive-displacement and is widely used in several industrial and commercial applications.

Components Involved in Functioning of Vane Pumps

The main components that comprise the system of a rotary vane pump include pump housing, outlet, installed rotor,inlet valve and vanes that meet at a common centre under spring force. The pump housing has two openings namely the inlet valve that is intended to be a vacuum safety valve and the outlet valve which is oil-sealed. The components are present inthe working chamber which in turn is situated within the pump housing. Rotary vane pumps are fast, efficient and noiseless based as they are on a resourceful electromagnetic motor. Depending on the cylinder size and rotor, these pumps can bring in greater volumes per minute and hence they achieve higher vacuum faster. Special pump oil is needed for their smooth operation and achievement of maximum vacuums.

Applications of Rotary Vane Pumps

There are several reputed vane pump manufacturers in the country that offer pumps built with good mechanical efficiency. This ensures their smooth functioning in several applications; the most important being the automotive field.

Important Place in the Automobile Industry
The pump goes into the working of several parts of the vehicle such as:
• Power steering
• Braking
• Supercharging
• Automatic transmission
The vacuum pumps go along with braking boosters which offer braking in the bigger trucks. Besides automobiles, the vane pumps have found their way into light aircraftsystems too.
In the airplanes, they help in functioning of:
• Heating and altitude indicators
• Gyroscopic flight instruments

Low & Mid-Range Pressure Applications
Some low-pressure gas applications of the pump include evacuating refrigerant lines and controls of auto exhaust emission with secondary air injections.Other mid-range pressure applications of the pump include its use in carbonators for soft drink and espresso dispensing machines.

Laboratory Experiments
The rotary vane pumps have wound their way into the educational field by becoming indispensable for vacuum experiments in physics. Here, oil and pumped gas are mixed in the pump. Both these have to be separated from one another externally. When the outlet and inlet have a big chamber the oil drops fall as the gas rises. At the end both exit out through the outlet and they are thus separated from each other.

Summarizing
The vane pumps are a common feature in industrial, commercial and automotive industries in the country. The sizes of the internal components can be varied to suit the needs of each application. All vane pump manufacturers in India will vouch for their usefulness in automobiles of varying sizes, oil and laboratory settings as well as drink dispensers. The feature of sliding contact makes the vane pump a suitable optionfor liquids with low viscosity; however, they are unsuitable for high viscosity or high pressure applications. It is better to take the advice of vane pump manufacturers for obtaining the right pump for your application.
