I get it now, I looked up how a normal vane pump works. I see how the vanes slide out to create an expanding then a contracting volume as the rotor turns in the eccentric space in there. This video does an excellent job of showing how a balanced vane pump is balanced. Thx
Hi Sonal, here is the link to unbalanced pump. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-BnvzPoNSXCg.html It is called unbalanced because high pressure is only at one side of to shaft which creates force on the shaft only from one direction.
I do not understand what is going on there at all. I mean I get there are some sort of eccentric interlocking wheels or something but I don't really understand what what is happening is there a more simple version of this type of mechanism with with less parts or something
+John Smith At the center of the pump there is a rotating circular brow block, lets call it rotor. There are groves show with yellow colors on the rotor. Black vanes are free to slide in these groves. Sometimes there are springs behind the vanes located closer to rotation axis of rotor. These springs or centrifugal force of rapid rotation forces the vanes outward. Outward motion of vanes restricted by elliptical shape carved on the pump body. The depth of elliptical carving, the height of vanes and the rotor is the same. When the rotor is forced to rotate by an electrical motor, the oil coming from blue pipes into elliptical chamber is forced by vanes to red pipes with increased pressure. Note that the elliptical shape of the carving forces vanes in and out in appropriate places to cause the pressure increase of the oil. Pump cover, not shown in the drawing, seals the rotor, vanes and elliptical chamber very tightly to minimize the losses.
+Alex Xie Thank you for comment and visiting my channel. Is springs necessary? Can't it be working just by centrifugal force generated by fast rotation?
mekanizmalar I think springs are better.Depending on centrifugal force only is not enough to maintain vanes to keep contact on the surface of the cavity.Maybe.
+Alex Xie I don't know which one better. Some design uses spring some don't. I guess vanes are heavy and motor rotating faster, no spring will be necessary. However vanes are some kind strong plastic, springs will definitely be required. But putting springs to my animation would be better.
+mekanizmalar I subscribe to your channel and watch most of the videos you post. You do a good job showing how things work. Sometimes a small detail is left out, but overall your videos are very accurate.
