The concept of vortex pump applications

by rotating vortex pump, the power of the impeller on the liquid in the liquid movement in the direction to the liquid to the kinetic energy of the impulse to pass in order to realize the transmission of liquid pump. Impeller for the thick disk, there are a lot of small radial blade on both sides of its outer edge. With the blade on the corresponding parts of the pump shell has a first-class section of the annular flow, the flow channel was divided into a separate tongue for suction and discharge on both sides, respectively with that of the pump suction and discharge piping. Liquid in the pump with the impeller rotation to produce centrifugal force, flung outward into the annular flow in the pump casing, and in the flow channel was forced to return under the restrictions of back into the back of the blade root is another way. Therefore, the liquid between the blade and annular flow movement trace, for the stillness of the pump shell is a kind of forward spiral; For rotation of the impeller is a kind of backward spiral. Vortex pump is named after the deep liquid of the spiral movement. Liquid can obtain energy in many straight blade, till the last from the outlet. Vortex pump work like some multistage centrifugal pump, not for the vortex pump volute centrifugal pump or guide vane of the energy conversion device. Vortex pump is mainly through times of continuous work way of energy transfer to the liquid, so can produce high pressure. In the process of energy transfer, because many times the impact of liquid, energy loss is bigger, the low efficiency of the pump, is commonly ~ %. Vortex pump is only applicable to small flow ( ~ m /, high head, Of meters of occasions, such as fire pump, small refueling vehicle gasoline pump, boiler feed water pump, etc. Vortex pump can deliver high volatile and containing gas liquid, but should not be used to handle liquid viscosity is greater than the mpa/SEC thicker and unclean liquid containing solid particles. The characteristics of the vortex pump flow is small, head high, with self-priming function, can be used to transport the viscosity is less than the degree of E no solid particles and liquid similar to water. Such as gasoline, kerosene, alcohol, etc. , can be used as a small steam boiler filling water, chemical, pharmaceutical, building water supply and other purposes. Flow components and stainless steel material can be used for conveying of acid and alkali corrosive liquid. Medium temperature was minus ~ + c. From the structure can be divided into; Single, double, multiple; Straight league form etc.
