Description

Technical Field

[0001] The utility model relates to the technical field of centrifugal pumps, in particular to a dry horizontal spiral centrifugal pump. Background Art

[0002] The dry horizontal spiral centrifugal pump uses its special three-dimensional spiral blades to organically combine the volumetric reasoning effect of the spiral and the centrifugal effect of the blades to enable the medium to obtain energy. Therefore, it has the characteristics of both a volumetric pump and a vane pump, and is the product of the combination of the two. The spiral centrifugal pump is a new type of non-clogging pump, which has a very wide application prospect in various industries and sewage treatment operations such as papermaking (transportation of high-concentration pulp), fisheries (transportation of live fish, live shrimp, etc.), sugar industry, food (transportation of potatoes, beets and other block vegetables), metallurgy, environmental protection (river dredging; transportation of silt and sand), chemical industry, etc.
