65WB-50-type vortex pump design
Abstract: Vortex pump by rotating impeller forces the liquid in the liquid to the liquid movement in the direction of the impulse to pass in order to achieve transfer of kinetic energy of the pump liquid. Impeller for the first thick disk, in which there are many on both sides of the outer edge of the small radial blades. With the corresponding parts of the pump blades have a first-class section of the shell of the annular flow channel, the entire flow channel separated by a sub-lingual absorption become exclusive two sides, respectively, and the suction pump, associated piping row. Impeller pump with the rotating liquid with a centrifugal force generated when the outside shell thrown into the ring pump flow and the shape of the flow constraints are forced to return to the roots from the leaves into the back of another leaf Road. Therefore, the liquid in the leaves and annular flow of movement between the trace of the static pump shell is a spiral forward; and for the rotation of the impeller is a backward spiral. Vortex pump that is a result of fluid movement, named after such a vortex. Liquid can be for multiple entry and access to energy between leaves, until the final discharge from the outlet. Vortex pumps work like a multi-stage centrifugal pump some, but not as centrifugal vortex pump volute or guide vane as the energy conversion device. Mainly through the vortex pump Zuogong many ways for the energy transfer to the liquid, they are able to generate higher pressure. In the energy transfer process, as a result of the repeated impact of liquid, the larger energy loss, the lower the efficiency of pump is generally 20 to 50%. Vortex pump requirements apply only to a small volume (1 ~ 40 m 3 / h), high head (up to 250 meters) of occasions, such as fire pumps, aircraft refueling vehicle the fuel pump, boiler feed pump and other small. Vortex pumps can be highly volatile and transmission fluids contain gas, but the viscosity should not be used to transport more than 7 seconds Pago • more viscous liquid and solid particles containing the liquid is not clean. The characteristics of vortex flow pump small, head high, with a self-priming function, can be used to transport less than 5 ° E viscosity of the non-solid particles and liquid similar to water. Such as gasoline, kerosene, alcohol and so on, almost on a daily basis can be used as a small steam boiler, chemical, pharmaceutical, high-rise water supply purposes. There are stainless steel flow components can be used to transport materials such as acids, alkali corrosive fluids. Transmission medium temperature of -20 ~ +80 degrees. From the structure can be divided into single-stage, dual-level, multi-level; Direct form.
