Improving process of single-stage centrifugal water pump impeller

Abstract

The invention discloses an improving process of a single-stage centrifugal water pump impeller. The improving process includes the following steps: calculating, obtaining an impeller diameter value which can satisfy actual needed flow through calculation of the actual needed flow; and machining, shortening an impeller diameter value to the obtained impeller diameter value which can satisfy the actual needed flow through calculation. According to the improving process of the single-stage centrifugal water pump impeller, the rated water yield can be reduced under the satisfaction of production needs, and the throttle controlled quantity can be reduced.

Description

technical field [0001] The invention relates to the technical field of centrifugal pumps, in particular to a single-stage centrifugal pump impeller transformation process. Background technique [0002] A pump is a machine that transports liquid or pressurizes the liquid. It transfers the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. Centrifugal pump is designed according to the high-speed rotation of the impeller blades to drive the water to rotate and throw the water out, so as to achieve the purpose of transportation. The following content will introduce a single-stage centrifugal water pump in the prior art in detail. [0003] Please refer to figure 1 , figure 1 It is a structural schematic diagram of a single-stage centrifugal water pump in the prior art. [0004] The single-stage centrifugal pump mainly includes base 1, pump body 2, impeller 3, mechanical seal 4, volute pump casing 5, water retainin...

Problems solved by technology

In order to ensure that the water output of the water pump matches the actual required water volume, people usually perform throttling control at the outlet of the water pump, which results in high power consumption.

[0007] In addition, the throttling control of the water volume at the outlet of the pump will increase the outlet pressure, causing the flange connection of the relevant pipelines to be unreliable, causing water leakage problems, and adversely affecting normal production
