Problems solved by technology

[0005] For vortex pumps with different performance requirements, such as high head at the closing point, performance with a steep drop in the flow-head performance curve, performance requirements at low head at the closing point, high flow rate, and the requirement for a much larger flow rate, it used to be a replacement Different pump bodies do not have modularization considerations. For the requirement of increasing the flow rate, some have the structure of adding a front centrifugal pump, but the centrifugal pump with the same impeller diameter will not increase the flow rate of the impeller of the vortex pump too much, and cannot According to the actual selection of customers

Abstract

The invention discloses a high-efficiency high-pressure high-flow non-blocking rotation modularization multifunctional vortex pump which comprises vortex impellers with multiple performances and paired volutes. The multifunctional vortex pump is characterized in that the vortex impellers with the multiple performances and the paired volutes are detachable and replaceable series modularization parts with the same installing size. The high-lift high-efficiency multi-performance high-flow modularization series vortex pump which does not need to consider the axial clearance or is controllable in axial clearance can be manufactured.

Description

technical field [0001] The invention relates to a multifunctional vortex pump with modular design, which improves the performance of the vortex pump and expands the application range of the vortex pump. Background technique [0002] The specific speed of the vortex pump is usually between 6 and 50. It is a small-flow, high-lift pump, suitable for conveying liquid or gas-liquid mixture with a viscosity not greater than 5°E, no solid particles, and no impurities. Compared with the centrifugal pump with the same performance, the vortex pump has the advantages of small size, light weight, simple structure and low cost; it has a steep head characteristic curve, so it is not sensitive to the pressure fluctuation in the system. The vortex pump can realize the mixed delivery of vapor and liquid. This is of great significance for pumping volatile liquids containing gas and high-temperature liquids with high vaporization pressure. [0003] The radial and axial clearance requirement...
