CWB magnetic whirlpool pump impeller is a disc, the circumference of the blade is uniformly arranged radially.

An annular flow channel is formed between the pump body and the impeller, and the suction inlet and discharge outlet are in the outer circumference of the impeller.

There is a baffle between the suction inlet and the discharge outlet, so as to separate the suction inlet and the discharge outlet.

We divide the fluid in the pump into two parts: the fluid between the blades and the fluid in the flow channel.

When the impeller rotates, under the action of centrifugal force, the circumferential velocity of the liquid in the impeller is greater than the circumferential velocity of the liquid in the flow channel, so the "annular flow" as shown in Figure 1 is formed.

And because the liquid from the suction inlet to the discharge outlet moves forward with the impeller, the combination of these two movements makes the liquid produce the same "longitudinal vortex" as the impeller.

Thus get the name of the vortex pump.

In particular, the circumferential velocity of the liquid particle in the channel of the pump body is less than the circumferential velocity of the impeller.

In the longitudinal vortex process, the liquid particles enter the impeller blades several times and transfer energy to the liquid particles in the flow passage through the impeller blades. Each time a liquid particle passes through a blade, it gains energy.

This is also the same impeller diameter, vortex pump than other vane pump head high reason. Not all liquid particles pass through the impeller, and as the flow rate increases, the "annular flow" weakens.

When the flow rate is zero, the "annular flow" is the strongest and the head is the highest. Because the fluid in the flow channel is transferred energy through liquid impact.

The main features

Magnetic vortex pump has the following characteristics:

1. High head. Small flow rate. Specific revolution is generally less than 40

2. Simple structure. Small size and light weight

3. It has self-lubricating circuit. Reduce the radial force of the impeller

4. Use cantilever blades. Reduce the radial force of the impeller

5. With the increase of the viscosity of the conveying medium, the efficiency of the pump drops sharply, so the medium degree is not greater than 5× 10-6m3 /S.

Scope and purpose of use

It is widely used in shipbuilding, light textile, chemical industry, metallurgy, machinery manufacturing, aquaculture, fixed fire control and pressure regulation, heat exchange unit, agricultural remote sprinkler irrigation and other departments.
