Corrosion-resistant stainless steel "target=_blank>What is the difference between a stainless steel gear metering pump and a gear pump?
There may be no difference in some industry uses, or there may be no difference in some people's eyes. But for a particular process use, measuring two more words is a far cry. Stainless steel "target=_blank> stainless steel gear metering pump is a gear pump, only a specific gear pump can be called a gear metering pump, while stainless steel "target=_blank> stainless steel gear metering pump is a kind of metering pump, so stainless steel" Target=_blank>The stainless steel gear metering pump has a metering characteristic.
The following is a way to introduce the difference between stainless steel "target=_blank> stainless steel gear metering pump and gear pump:
Stainless steel "target=_blank> stainless steel gear metering pump is a kind of gear pump. Only a specific gear pump can be called a gear metering pump. The gear metering pump is a kind of pump product with metering characteristics. The gear metering pump has been specially designed. Special materials have been selected, processed by special processes, special equipment, and specially processed. More and more applications are applied to the equipment.
The working principle of the gear pump: The concept of the gear pump is very simple, that is, its most basic form is that two identically sized gears mesh with each other in a tightly fitting housing. The interior of the housing resembles an "8" shape. Two gears are mounted inside, and the outer diameter and both sides of the gear are closely matched with the housing. The material from the extruder enters the middle of the two gears at the suction port and fills this space, moves along the housing as the teeth rotate, and finally exits when the two teeth mesh.
A gear pump is also called a positive displacement device, that is, a piston in a cylinder. When one tooth enters the fluid space of the other tooth, the liquid is mechanically squeezed out. Because the liquid is incompressible, the liquid and the teeth cannot occupy the same space at the same time, so that the liquid is eliminated. This phenomenon occurs continuously due to the continuous engagement of the teeth, thus providing a continuous discharge at the pump outlet, which is the same amount per revolution of the pump. As the drive shaft rotates uninterrupted, the pump discharges fluid without interruption. The pump flow is directly related to the pump speed. In fact, there is a very small amount of fluid loss in the pump, which makes the pump's operating efficiency not reach 100%, because these fluids are used to lubricate both sides of the bearing and the gear, and the pump body can never be fitted without clearance. The fluid cannot be discharged 100% from the outlet, so a small amount of fluid loss is inevitable. However, the pump can still operate well, and for most extruded materials, it can still achieve an efficiency of 93% to 98%.
Stainless steel "target=_blank> stainless steel gear metering pump advantages:
High precision ---- under various conditions of temperature, viscosity and pressure, it can ensure stable and repeatable flow rate, and the measurement accuracy is up to 0.3%. Stable flow, no pulsation output. For more information, please contact Zhitu Machinery Technology to answer the questions related to gear metering pumps.
