How Gear Oil Pump products work

When the driving gear of Gear Oil Pump products rotates, the gears in the oil suction chamber are disengaged, and the teeth of the gears exit between the teeth, which increases the sealing volume and forms a partial vacuum. Under the action of the external atmospheric pressure, the oil in the oil tank passes through the oil suction pipeline , The oil suction cavity enters between the teeth. As the gear rotates, the oil sucked between the teeth is brought to the other side and enters the oil pressure chamber.

This is when the gears enter into mesh, so that the sealing performance is gradually reduced, and the oil between the gears is squeezed out, forming the oil-pressing process of the gears. When the gears are meshed, the tooth contact line separates the oil suction chamber and the oil pressure chamber, and plays the role of oil distribution. When the driving gear of Gear Oil Pump products is driven by the motor to rotate continuously, the gear is disengaged from the meshing side. Since the sealing volume becomes larger, oil is continuously sucked from the oil tank, and the gear teeth enter the meshing side. Due to the reduction of the sealing volume, it is continuously The oil is discharged to the ground, forming a continuous cycle process.
Gear Oil Pump products work with two gears intermeshing and rotating, and the medium requirement is not high. The general pressure gear oil pump force is below 6MPa, and the flow rate is large.
Gear Oil Pump products are equipped with a pair of rotary gears in the pump body, one active and the other passive. Depending on the mutual meshing of the two gears, the entire working chamber in the pump is divided into two independent parts. A is the suction chamber, B is the discharge chamber. When the Gear Oil Pump products are running, the driving gear drives the driven gear to rotate, and when the gears are engaged to disengaged, a partial vacuum is formed on the suction side (A), and the liquid is sucked in. The sucked liquid fills the tooth valleys of the gears and is brought to the discharge side (B). When the gears are engaged, the liquid is squeezed out to form high-pressure liquid and is discharged out of the pump through the pump discharge port.
