driving device
Gear pumps are driven by individual motors, which can effectively block upstream pressure and flow fluctuations. The pressure pulsation at the outlet of the gear pump can be controlled within 1%. Using a gear pump on the extrusion production line can increase the flow output speed, reduce material shear and residence time in the extruder.
External gear pump is a widely used type of gear pump, usually referred to as an external gear pump. Its structure is shown in Figure 5-14, mainly composed of a driving gear, a driven gear, a pump body, a pump cover, and a safety valve. The sealed space formed by the pump body, pump cover, and gear is the working chamber of the gear pump. The axles of the two gears are respectively installed in the bearing holes on the two pump covers, and the driving gear shaft extends out of the pump body and is driven to rotate by the electric motor. The external gear pump has a simple structure, light weight, low cost, reliable operation, and wide application range.
When the gear pump is working, the driving wheel rotates with the electric motor and drives the driven wheel to rotate accordingly. When the meshing teeth on the suction chamber side gradually separate, the volume of the suction chamber increases, the pressure decreases, and the liquid in the suction pipe is sucked into the pump; The inhaled liquid is divided into two paths and pushed into the discharge chamber by the gear in the tooth groove. After the liquid enters the discharge chamber, due to the disengagement of the teeth of the two gears, the liquid is squeezed and enters the discharge pipe from the discharge chamber. When the driving gear and the driven gear stop rotating, the pump can continuously suck in and discharge liquid intermittently.
The pump body is equipped with a safety valve. When the discharge pressure exceeds the specified pressure, the conveying liquid can automatically open the safety valve, allowing the high-pressure liquid to return to the suction pipe.
Internal gear pump, which consists of interlocking internal gears and their crescent shaped components, pump casing, etc. The function of the crescent shaped component is to separate the suction chamber from the discharge chamber. When the driving gear rotates, a local vacuum is formed at the place where the gear disengages, and the liquid is sucked into the pump to fill the teeth of the suction chamber. Then, it enters the discharge chamber in two paths along the inner and outer sides of the crescent shaped part. At the meshing point of the gear teeth, the liquid present between the teeth is squeezed and sent into the discharge pipe.
