Efficiency of External Gear Pump

Proceedings of Higher Educational Institutions. Маchine Building, 2021
The purpose of the research was to analyze the load characteristics of external gear pumps. As the initial data, the results of factory tests of the NMSH and SH pumps, provided by HMS Livgidromash JSC, were used. The load characteristics of the gear pump NMSH32-10 were constructed, and the dependence of this pump efficiency on the dimensionless ...

Analysis of External Gear Pump Failure

Advanced Materials Research, 2013
Several typical failures of external gear pump are presented. The reasons of the pump failure are analyzed in detail. Solutions of the failure are proposed. In order to improve the efficiency of pumps maintenance and reparation, a new kind of tool is mentioned which could predict the life of gear pump before failure occurred.

A Design Procedure for Multistage External Gear Pumps

BATH/ASME 2020 Symposium on Fluid Power and Motion Control, 2020
Abstract In this work, the authors present a robust and integrated procedure for the design of multi-stage gear pumps to be used in dry sump system applications. Based on the target delivery flow rate, rotational speed and fluid properties, the developed iterative method enables to directly obtain the geometrical features and the working
