Abstract

The invention discloses a vertical centrifugal pump and a water supply system with the vertical centrifugal pump, the vertical centrifugal pump comprises a flow guide device, the flow guide device comprises a first pipe part and an impeller structure arranged in the first pipe part, and a first water outlet pipe is arranged on the outer side wall of the first pipe part; the pump body comprises a second pipe part, the second pipe part is arranged on the periphery of the first pipe part in a sleeving mode, a backflow channel is formed between the second pipe part and the first pipe part, the backflow channel is communicated with the water outlet end of the first pipe part, the first water outlet pipe is provided with a first water outlet extending out of the second pipe part, and the second pipe part is provided with a second water outlet which is communicated with the backflow channel. According to the vertical centrifugal pump and the water supply system with the vertical centrifugal pump, water can be supplied to a plurality of areas with different water supply pressure requirements at the same time, meanwhile, the continuous smoothness of liquid during flowing is improved, the water supply performance of the vertical centrifugal pump is improved, in addition, the pump body structure can be simple, and the cost is low. And the manufacturing cost of the centrifugal pump is reduced.

Description

technical field [0001] The present invention generally relates to the technical field of pump body, in particular to a vertical centrifugal pump and a water supply system with it. Background technique [0002] In a water supply system it is often necessary to supply water to at least two different pressure zones. In order to meet the above requirements, the water supply system needs to be equipped with more than two sets of water supply equipment containing vertical centrifugal pumps, and more than two sets of water supply equipment are used to output water of different pressures to supply water to more than two different pressure areas. water supply. [0003] However, since more than two sets of water supply equipment need to be configured in the water supply system, not only the cost of the water supply system is high, the purchase cost of the user is increased, but also the occupied area of ​​the water supply system is increased. Contents of the invention [0004] In ...
