Schematic of a hydraulic gear pump drawn by computer. It is a set of three schemes.
A gear pump is a type of hydraulic pump consisting of 20000 gears enclosed in a very tight housing. It transforms the kinetic energy in the form of torque, generated by a motor, into hydraulic energy through the oil flow generated by the pump.
This pressure oil flow is used to normally generate the movement of the actuator installed in the machine / application.
ComponentsThe main element of the pump is the pair of coupled gears. The gear pair is formed by the drive shaft / motor (which is driven by the motor shaft) and driven shaft. The driving shaft rotates the driven shaft under the principle of displacement caused by the contact between the teeth of the axle gears. Functioning
When the pump is operated, the oil enters through the inlet (suction) port of the pump due to the depression created by separating the teeth from each other with respect to the other gear. The oil is transported through the flanks of the gear teeth until it reaches the pump outlet, where, when the teeth of the drive shaft are brought together with those of the drive shaft, the oil is drawn into the outlet (pressure) .
The use of external gear pumps on the market is very common because it is a compact, powerful, robust and cost-competitive product.
