WEAR BEHAVIOUR OF VANES FOR A ROTARY VANE

Abstract This study presents tribological properties of various graphite materials of vanes for rotary vane expanders. A test device was developed in order to measure the wear and power dissipation under conditions similar to a real operation of a vane expander.

Volumetric expanders for low grade heat and waste heat

2016/5/1The vane expanders can be classified into two types, the rotary vane expander, and revolving vane expander. The working principle and components of vane expander are shown in Fig. 3. Download : Download high-res image (275KB) Download : Download full ., .

Macroscopic Superlow Friction of Steel and Diamond

Energy dissipation due to friction and wear is reducing the energy efficiency and reliability of mechanical systems. Thus, great efforts are being made to minimize friction for technical applications. In our present work, we investigate the tribological behavior of stainless steel 100Cr6 with a-C:H and a-C:H:Si coating lubricated with a surface-active formanisotropic 1,3-diketone. The results

Rotary vane pump

A rotary vane pump is a positive-displacement pump that consists of vanes mounted to a rotor that rotates inside a cavity. In some cases these vanes can have variable length and/or be tensioned to maintain contact with the walls as the pump rotates. It was invented by Charles C. Barnes of Sackville, New Brunswick, who patented it on June 16
