Embodiment Construction
[0012] Below in conjunction with accompanying drawing, the present invention is further described:
[0013] A tangential small-flow high-lift pump, comprising a pump body 2, a pump cover 5, a pump shaft 6, an impeller 4, an impeller nut 1 and a gasket 3, a pump body 2, a pump cover 5, a pump shaft 6, an impeller 4, and an impeller The connection relationship between the nut 1 and the gasket 3 is the same as that of the prior art, so it will not be described in detail here. It is characterized in that the impeller 4 is composed of the impeller hub 7, blades 8, and blade support tooth plates. The blades are straight blades 8, and the impeller There are straight blades 8 in the circumferential array of the hub 7, and the blade supporting tooth plates are tooth-shaped. The blade supporting tooth plates are composed of support rings 9 and plate teeth 10 around the support rings. It is fixedly connected with the impeller hub 7, and the upper end is fixedly connected with the straigh...
