Seeking the formula for the radial force in gear pumps
Thread Content
May I ask for the formula for the radial force in gear pumps? There’s another question (a bit silly). . ): The gear oil pump should be considered a positive-displacement pump. Since oil is an incompressible fluid, how is oil pressure generated?
It is recommended to check the materials first if you have any questions
Back pressure: You don’t understand the structure of gear pumps. Gear pumps are further divided into internal gear pumps and external gear pumps, etc. Their working principle is the same, but their structures are completely different. Internal gear pumps have crescent plates as well. In the case of external gear pumps that we commonly use, when the driving gear and the driven gear engage with each other, negative pressure is generated to draw in the liquid; when the two gears separate, high pressure is created, which pushes the liquid out. By the way, for positive displacement pumps, the formula for shaft power is P = 10^5 × (Pd – Ps) × Q / 102 × η, where Pd is the outlet pressure, Ps is the inlet pressure, and Q is the flow rate in m/s
