2. Working Principle of Gear Pump

A gear pump operates on the principle of positive displacement, where fluid is drawn into the pump and then forced out under pressure. The primary types of gear pumps used in excavators are:

2.1 External Gear Pump

• Consists of two meshing gears (a driving gear and a driven gear) enclosed in a housing.

• As the gears rotate, fluid is trapped between the gear teeth and the pump casing.

• The fluid is carried from the inlet (suction) side to the outlet (discharge) side, where it is expelled due to the meshing of the gears.

2.2 Internal Gear Pump

• Features an inner rotor (drive gear) and an outer rotor (idler gear).

• The inner gear rotates eccentrically, creating expanding and contracting chambers that draw in and expel fluid.

• Known for smoother operation and higher efficiency compared to external gear pumps.

Both types rely on the meshing action of gears to create a vacuum for suction and pressure for discharge, ensuring continuous hydraulic fluid flow.
