Oil Trapping in Gear Pumps： Causes & Effects in Hydraulic Systems
1.What Is Oil Trapping? Oil trapping occurs when a small volume of hydraulic fluid becomes sealed between meshing gear teeth during rotation. As the gears continue to rotate, this trapped oil has no direct flow path to the inlet or outlet. 2.How Does Oil Trapping Occur in Gear Pumps? Two gear teeth come into full […]
How to Reduce Radial Force Imbalance in Gear Pumps
1️⃣ Optimize Port Plate & Housing Design Well-designed inlet and outlet ports help redistribute pressure more evenly around the gear circumference. Optimized port geometry reduces pressure gradients and lowers net radial force. 2️⃣ Use Pressure-Balanced or Compensated Designs Modern gear pumps adopt: Axial pressure compensation Radial force balancing grooves Floating bushings These features automatically adjust […]
