A webinar presented by the International Fluid Power Society on the prevention and management of fluid injection injuries cites a study by Snarski and Birkhahn, two emergency department doctors at the New York Methodist Hospital. And it contains some sobering statistics:
Fluid injection injuries are relatively rare … Read more
While doing some fact checking for a consulting job, I had cause to review Australian Standard AS 2671; Hydraulic Fluid Power-General Requirements for Systems. This Australian Standard is basically the International Standard, ISO 4413 with some amendments based on the local advisory committee’s input.
One of the advantages of variable-displacement pumps with hydraulic or electro-hydraulic displacement control, or load-sensing control, is their low standby pressure. Meaning, when pump output isn’t required, the pump ‘stands by’ at a relatively low pressure, and usually at zero flow — other than that necessary for the make-up of internal leakage.
