How Does A Vane Pump Work?
Total Articles: 6
Vane pumps have been in use for a long time now. Ever since LP gas and fuel oils came into existence, there was a need for a pump that would help handle these gases efficiently. While there are other pumps that have the ability to deal with gases, but when there are refrigerants, gasoline, ammonia, fuel oils and alcohol are involved, you will need a specialized pump that would help handle these moderate viscosity liquids. Depending on the amount of gas that will be dealt with, you can choose from the various number of vane configurations that are available. Starting from external vane to swinging vane to sliding vane and rolling vane, there is no shortage of the types of vane pump that are available and it is important that you keep an eye on the type of gas that will be used. There are two big reasons why vane pumps have become so popular; first, they have the capacity to handle fluids in extreme temperatures. The lowest temperature recorded is – 25 F and the highest has been 500 F. Vane pump manufacturers make sure that the pumps are made to reach their peak performance every time they are used.
How they work?
As mentioned above, vane pumps are found with various configurations, but the operating system is the same for all. Here is a detailed description of how the pump works:
There are two things that help operate the pump smoothly; the cycloidal cam and slotted rotor. The rotor works in tandem with the cycloidal came because the latter provides total support to it. The rotor together with the cam will form a crescent shape and the blades are fit on the slots. When the pump is switched on, the rotor will start rotating. When this happens, the fluid will enter the pump and all the respect vanes will start working. However, the pump maintains a very good suction to help the fluid enter properly.
Once the fluid starts to enter the pump, it has to reach the chamber. For this, the cam has enough holes that creates pockets by the rotor, vane, side plate and cam.
Last, but not the least comes the step where the fluid reaches the discharge port. The rotor will rotate and the fluid will enter while the vane will sweep that liquid to the other side of the crescent. With the holes in the cam, the fluid will be squeezed and slowly the fluid will reach the exit port and the function of the pump will be completed.
A very big advantage of using vane pumps is that you can be rest assured that the fluid will be pumped carefully and very systematically. Another reason why vane pumps are becoming excessively popular is because of their ability to handle high pressure for the thinnest of liquids. If you are in search for such pumps, you should try searching online with vane pump manufacturers India. Choose from the type of pump your need according to the purpose it will serve.
