English Abstract
This study demonstrates the characteristics of gear pump; it helps to understand the gear pump performance.
The effects of parameters (discharge pressure, suction pressure, rotation speed and temperature) on pump performance are considered separately.
When the pump is operating at constant suction pressure, pump speed and temperature, flow rate is decreased with increasing differential pressure across the pump, and it leads to a decrease in volumetric efficiency, but the mechanical power increases.
Mechanical and volumetric efficiency limit the overall efficiency.
When the pump is operating at constant discharge pressure, pump speed and temperature, flow rate is affected by slip at high suction pressure but in low suction pressure flow rate is affected by slip and cavitations inception.
Maximum overall efficiency is obtained at suction pressure before cavitations inception.
The pump has best volumetric efficiency at high speed rotation but mechanical efficiency is reduced in high speed, Maximum overall efficiency is in the mid-range of pressure rise.
The volumetric efficiency and power consumption decrease as the oil temperature increases.
