A novel design on smooth rotor profile with meshing clearance for screw vacuum pump

Advances in Mechanical Engineering, 2022
Cross-section profile of rotor takes a great effect on the performance of dry-screw vacuum pump. A novel smooth rotor profile consisting of eight segments of curves, including arcs and conjugate correction curves is proposed.

Numerical Simulation and Experimental Study of a Small-Scale Vacuum Fish Pump

Journal of Marine Science and Engineering
The existing vacuum fish pump is too large and difficult to move, which is difficult to apply to small fishing vessels. However, the development of a small vacuum fish pump is not a single scaling of the existing vacuum fish pump but requires the support

Real time monitoring of transtibial elevated vacuum prostheses: A case series on socket air pressure. [PDF]

PLoS ONE, 2018
Prosthetic elevated vacuum is a suspension method used to reduce daily volume changes of the residual limb. Evaluation of the effectiveness of these systems is limited due to a lack of correlation to actual socket air pressure, particularly during ...
