Evaluation of Composite Vane Materials for Rotary Sliding Vane Compressors
The physical performance characteristics of composite materials used for vanes in rotary, sliding-vane compressors, in general, are several orders of magnitude more difficult to quantify for design purposes than most homogeneous materials. This arises from the numerous variables that influence the response of these materials under the severe environmental conditions existing in such compressors...
متن کاملVane Dynamics Analysis of a Tilted Vane Rotary Compressor
An analytical model of vane dynamics in a tilted vane rotary compressor is presented. With the geometric relationship of the vane in a tilted slot, and the roller, the kinetic equations were derived for evaluating the reciprocating inertial force of the vane, and the chamber volume equations were obtained for calculating pressure history inside the compression chamber. The empirical friction co...
متن کاملVane Behavior in Vane Compressors Under Start-up Operation
Vane oompressors can not maintain contact between a vane tip and a cylinder wall under start-up operation since backpressure acting on the vane is not sufficient. We theoretically analyzed transient behavior of the vane under the start-up operation by taking account of changes of the backpressure and discharge pressure after compression starting. The validity of the theoretical analysis was con...
متن کاملImprovement Of Abnormal Wear Between The Vane-slot And Vane In Rotary Compressor
The reason for the abnormal wear between the vane-slot and the vane in the rotary compressor is analyzed in this paper. Firstly, the influence of lubrication at the clearance, the machining equipment accuracy and oil circulation (oil flow rate) is analyzed. Then the material characteristics including the hardness of the vane and vane-slot, the surface treatment of the vane and the deformation o...
متن کاملMatching Diffuser Vane with Return Vane Installed in Multistage Centrifugal Pump
The effects of the diffuser vane on the performances of the multistage centrifugal pump were investigated experimentally, taking account of the interactions among the diffuser vane, the return vane, and the next stage impeller. It is very important to match well the diffuser vane with the return vane, for improving the hydraulic efficiency of the pump. The efficiency may be more improved by mak...
