Advantages of VICKERS gear pump in operation

The concept of VICKERS gear pump is very simple, that is, its basic form is two gears of the same size meshing and rotating with each other in a tightly fitting housing. The interior of this housing is similar to an "8" shape, with two gears installed inside, and the outer diameter and two sides of the gears tightly fitting with the housing. The material from the extruder enters the space between the two gears at the suction port and fills this space. It moves along the housing with the rotation of the teeth, and is discharged when the two teeth mesh. In terms of terminology, VICKERS gear pumps are also known as positive displacement devices, which are like pistons in a cylinder. When one tooth enters the fluid space of another tooth, the liquid is mechanically squeezed out. Because liquids are incompressible, liquids and teeth cannot occupy the same space at the same time, thus eliminating liquids. Due to the continuous meshing of the teeth, this phenomenon occurs continuously, thus providing a continuous discharge at the pump outlet. The amount discharged is the same for each rotation of the pump. As the drive shaft rotates continuously, the pump also continuously discharges fluid. The flow rate of a pump is directly related to its rotational speed.

Gear pump is a rotary pump that relies on the change and movement of the working volume formed between the pump cylinder and the meshing gear to transport liquid or increase its pressure. Two enclosed spaces are composed of two gears, a pump body, and front and rear covers. When the gears rotate, the volume of the space on the disengagement side of the gears increases from small to large, forming a vacuum that sucks in the liquid. The volume of the space on the meshing side of the gears decreases from large to small, and the liquid is squeezed into the pipeline. The suction chamber and the discharge chamber are separated by the meshing line of two gears. The pressure at the discharge port of a gear pump depends on the magnitude of the resistance at the pump outlet.

Gear pump, also known as positive displacement device, is like a piston in a cylinder. When one tooth enters the fluid space of another tooth, because the liquid is incompressible, the liquid and the tooth cannot occupy the same space at the same time, so the liquid is mechanically squeezed out. Due to the continuous meshing of the teeth, this phenomenon occurs continuously, thus providing a continuous discharge at the pump outlet. The amount discharged is the same for each rotation of the pump. As the drive shaft rotates continuously, the pump also continuously discharges fluid. The flow rate of a pump is directly related to its rotational speed.

Gear pumps have the characteristics of self-priming ability, independent flow rate and discharge pressure, and no suction valve or discharge valve on the pump casing. They have a simple structure, uniform flow rate, and reliable operation. However, they have low efficiency, high noise and vibration, and are prone to wear. They are mainly used to transport various oils that are non corrosive, non solid particles, and have lubricating ability. The temperature generally does not exceed 70 ℃, such as lubricating oil, edible vegetable oil, etc.
