Embodiment Construction

[0025] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0026] Such as figure 1 The self-priming multi-stage vortex pump shown includes a pump body with a vortex pump chamber inside, a pump shaft 1 driven by a motor passing through the vortex pump chamber, and the pump shaft 1 is sleeved with a pump located in the vortex pump chamber. The impeller 2 and two vortex pump chambers are arranged parallel to each other in the pump body. The two vortex pump chambers are arranged in series and each vortex pump chamber is provided with an impeller 2 sleeved on the pump shaft 1. The pump body is provided with There is a water inlet 3 communicating with the first-stage vortex pump cavity, and a self-priming chamber 4 communicating with the last-stage vortex pump cavity is also provided on...

Abstract

The invention provides a self-suction type multistage peripheral pump and belongs to the technical field of water pumps. The problems that an existing self-suction pump is mostly a multistage pump, is low in lift and cannot be suitable for high-rise water use are solved. The self-suction type multistage peripheral pump comprises a pump body with peripheral pump cavities inside, and a pump shaft which penetrates the peripheral pump cavities and is driven by a motor. The pump shaft is sleeved with impellers located in the peripheral pump cavities. The multiple peripheral pump cavities are parallel to one another and are formed in the pump body, the multiple peripheral pump cavities are arranged in series, one impeller arranged on the pump shaft in a sleeving manner is arranged in each peripheral pump cavity, and a water inlet communicating with the first-stage peripheral pump cavity is formed in the pump body. A self-suction chamber communicating with the last-stage peripheral pump cavity is further formed in the pump body, and a gas-water separation structure is arranged in the self-suction chamber. The self-suction type multistage peripheral pump has the characteristics of a self-suction pump and a peripheral pump, the lift is effectively increased, and the self-suction type multistage peripheral pump is suitable for high-rise water use.

Description

technical field [0001] The invention belongs to the technical field of water pumps, and relates to a vortex pump, in particular to a self-priming multistage vortex pump. Background technique [0002] Water pumps are widely used in daily life and agricultural production. The vortex pump is one of them. The vortex pump generally includes an impeller, a motor and a pump body. The output shaft of the motor passes through the pump body and is fixedly connected with the impeller located in the pump body. For the existing single-stage pumps, if the head or the flow rate is to be increased, structural changes are required, which will increase the cost virtually for the manufacturer, and increase unnecessary consumption for the customer. The vortex pump lacks a multi-stage impeller structure, and the single-stage head is low, which cannot adapt to the ever-changing market, which brings confusion to customers when choosing a water pump. [0003] For this reason, the Chinese patent di...
