Pressure transients in an external gear hydraulic pump
Proceedings of the JFPS International Symposium on Fluid Power, 1993 A measurement technique, that extends and integrates former experimental activities, has been developed to detect the variation with time of tooth space pressure in an external gear pump by use of a pressure transducer fi tted in the driver gear. The pressure signal from the miniature strain gauge sensor mounted in the bottom of the tooth space is ...
