Question

For a vane motor, explain at least two ways the vanes can be kept against the cam ring.

Answer 1

Vane kept. -pretion of Quertion of Two wage against the ring the - Liquiel Ring pump 7 n liquiel sing pump is a gofarting positive diep lancement They are typically as a Vacuum pump, but can aho be used as a gas Compregor. The function of a liquid ring pump ie Similar to a rotary Vane pump, with the difference being that the Vaner are an integaal part of the dotos and churn a- rotating ting of liquid to a form the Comprecion - Chamber Seal Liquid ring pump are generally powered by an induction motor

o single and multistage - Liquid Ring - Syetem can be Single - or multistage. Typically a multistage pump will have upto two Compression stages on a Common shaft , In Vacuum Services, the attainable pressure reduction ip limited by the Vapor precaure of the ring - liquid, Ae the generated Vacuum approaches the Vapour pressure of the ring - liquid; the increasing Volume of Vapour released from ring aliquid dininishes the remaining Vacuum Capacity. The efficiency of a gyetem declines as a result. Liquid sing Vacuum pumpe Can Use my liquial Compatible with the process, provided it has the

appropriate vapor forcecure properties, ge the Sealant liquid Although mart Common Sealant is water, almost any liquid can be leed. The second most common is oil Liquid -ring vane can lower vacuum- pressure from about 70 mbar to - below I mbar.
