Product Description
Gear pump is a rotary pump that depends on the working volume change and movement formed between the pump cylinder and the meshing gear to transport liquid or pressurize it. Composed of two gears, the pump body and the front and back cover of two closed Spaces, when the gear rotates, the volume of the space on the side of the gear off from small to large, forming a vacuum, the liquid inhalation, the volume of the space on the gear meshing side from large to small, and the liquid squeezed into the pipeline. The suction cavity and the discharge cavity are separated by the meshing lines of the two gears. The pressure at the outlet of the gear pump depends entirely on the resistance at the pump outlet.
The concept of gear pump is very simple, its most basic form is two gears of the same size in a closely matched housing meshing rotation, the interior of the housing similar to the "8" shape, two gears installed inside, the outer diameter of the gear and both sides of the housing closely matched. The material from the extruder enters the middle of the two gears at the suction inlet and fills this space, moving along the housing with the rotation of the teeth, and finally discharging when the two teeth mesh.
In terminology, gear pumps are also called positive displacement devices, that is, like a piston in a cylinder, when a tooth enters the fluid space of another tooth, because the liquid is incompressible, the liquid and the tooth can not occupy the same space at the same time, so that the liquid is mechanically squeezed out. Due to the continuous meshing of the teeth, this phenomenon occurs continuously, and thus provides a continuous exclusion at the outlet of the pump, and the amount of discharge is the same with each turn of the pump. With the continuous rotation of the drive shaft, the pump continues to discharge fluid. Pump flow is directly related to pump speed.
In fact, there is a very small amount of fluid loss in the pump, because these fluids are used to lubricate the bearing and both sides of the gear, and the pump body can never be matched without a gap, so the fluid can not be 100% discharged from the outlet, so a small amount of fluid loss is inevitable, which makes the pump operating efficiency can not reach 100%. However, the pump still works well and can still achieve 93% to 98% efficiency for most extruded materials.
