Abstract

The invention provides a self-priming multistage vortex pump, which belongs to the technical field of water pumps. It solves the problem that most of the existing self-priming pumps are single-stage pumps, which have a low lift and cannot be used for high-rise water use. The self-priming multistage vortex pump includes a pump body with a vortex pump cavity inside, a pump shaft driven by a motor pierced in the vortex pump cavity, and an impeller located in the vortex pump cavity is sleeved on the pump shaft. There are several cavities arranged parallel to each other in the pump body. Several vortex pump cavities are arranged in series and each vortex pump cavity is provided with an impeller sleeved on the pump shaft. The connected water inlet, the pump body is also provided with a self-priming chamber connected with the last stage vortex pump chamber, and the self-priming chamber is equipped with an air-water separation structure. The invention has the characteristics of a self-priming pump and a vortex pump, effectively improves the lift, and 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...
