Rotary Gear Pump Working Mechanism

A rotary gear pump is a type of positive displacement pump that moves fluid by repeatedly enclosing a fixed volume and transferring it mechanically through the pump. This type of pump is commonly used for pumping high-viscosity fluids such as oil, adhesives, and polymers. Here’s a professional explanation of its working mechanism:ComponentsDriving Gear: This gear is connected to the motor and drives the operation of the pump.Driven Gear (Idler): This gear meshes with the driving gear and is driven by it.Casing (Pump Housing): Encases the gears and forms a chamber to direct fluid flow.Inlet and Outlet Ports: Openings in the casing where fluid enters and exits the pump.Bearings: Support the shafts of the gears and ensure smooth operation.Working MechanismFluid Entry:As the driving gear rotates, it turns the driven gear in the opposite direction due to their meshing teeth.The rotation creates a void or low-pressure area at the inlet side, causing fluid to be drawn into the pump chamber from the reservoir.Fluid Transport:The fluid is trapped between the gear teeth and the casing as the gears continue to rotate.This trapped fluid is carried around the perimeter of the gears from the inlet to the outlet side of the pump.During this movement, the fluid is isolated from the inlet, preventing backflow. • Power Transmission Gea...
