overview
Magnetically driven vortex pump is a new product that applies the working principle of permanent magnet coupling to vortex pump. It has the characteristics of reasonable design, process, full seal, no leakage, low flow, high head and corrosion resistance, and its performance has reached the level of similar foreign products. The static seal replaces the dynamic seal, so that the flow parts of the pump are in a perfectly sealed state, which solves the problems of running, bubbling and dripping that other pump mechanical seals cannot avoid. The selection of corrosion resistant, high-strength engineering plastics, corundum ceramics, stainless steel and other manufacturing materials, so it has good corrosion resistance, and can make the transported medium free from pollution. It has the advantages of compact structure, beautiful appearance, small size, low noise, reliable operation and easy maintenance. It can be widely used in chemical industry, pharmaceutical industry, petroleum industry, electroplating industry, food industry, film photography and printing industry, and scientific research institutions. National defense industry and other units pump acid, lye, oil, rare and precious liquid, venom, volatile liquid, as well as circulating water equipment, filter equipment. Especially easy to leak, flammable, explosive liquid pumping, the choice of this pump is more ideal.
principle:
Magnetic driven vortex pump is a vane pump. It is mainly composed of impeller, pump body and pump cover. The impeller is a disk with uniformly arranged blades radially around the circumference. An annular flow channel is formed between the pump body and the impeller, and the inlet and outlet are at the outer circumference of the impeller. There is a partition between the suction inlet and the discharge outlet, thereby separating the suction inlet and the discharge outlet. We divide the liquid in the pump into two parts: the liquid between the blades and the liquid in the flow channel. When the impeller rotates, under the action of centrifugal force, the circular speed of the liquid in the impeller is greater than the circular speed of the liquid in the flow channel, forming a "ring flow". And because the self-priming inlet and outlet liquid advance with the impeller, the synthesis result of these two movements makes the liquid produce the same "longitudinal vortex" as the impeller turns. Hence the name vortex pump.
It should be noted in particular that the circular velocity of the liquid particle in the flow channel of the pump body is less than the circular velocity of the impeller. In the longitudinal vortex process, the liquid particles enter the impeller blades for many times, and the energy is transferred to the liquid particles in the flow channel through the impeller blades. Every time a liquid particle passes through the blade, it gains secondary energy. This is also the reason why the vortex pump has a higher lift than other vane pumps under the same impeller outer diameter. Not all liquid particles pass through the impeller, and the "annular flow" weakens as the flow rate increases. When the flow rate is zero, the "annular flow" is strong and the head is high. Because the liquid in the flow channel transfers energy through the impact of the liquid.
