Abstract

The invention relates to a centrifugal chemical pump which comprises a pump body, an impeller and a pump shaft driving the impeller to rotate; wherein the pump body comprises an upper shell; the upper shell comprises a bottom plate, a ring-shaped lateral wall, a water inlet, a water outlet and a cog; the lateral wall is arranged on the edge of the bottom plate in a winding manner, the water inlet is arranged at the top end of the upper shell, the water outlet is arranged in the position of the lateral wall near the bottom plate, the cog is involute-structured, namely, the cog is arranged in the intersection position of the bottom plate and the lateral wall in a winding manner, both ends of the cog are respectively arranged at the both ends of the water outlet, and the thickness of the cog gradually turns smaller; the impeller arranged on the upper shell of the pump body comprises a rib wheel, a cover wheel and a plurality of main blades; wherein, the cover wheel is arranged above the rib wheel in an overlapping manner, the arc-shaped main blades are arranged between the rib wheel and the cover wheel. The centrifugal chemical pump can achieve reasonable pressure and flow rate, ensure low energy consumption and effectively prevent the pump shaft from being corroded.

Description

technical field [0001] The invention relates to a centrifugal chemical water pump, in particular to a centrifugal chemical water pump capable of achieving reasonable pressure and flow, low energy consumption and effectively protecting the pump shaft from corrosion. Background technique [0002] Centrifugal pumps are general-purpose machinery in industry and are widely used in various fields of the national economy. The impeller of the existing centrifugal pump imitates the hydraulic model. It is difficult to find the best parameters by this method, so it cannot achieve reasonable pressure and flow, and the energy consumption is also large. In addition, the pump shaft is not effectively isolated and protected, so it is easy to be separated from the Corroded by contact with chemical fluids. Contents of the invention [0003] The technical problem to be solved by the present invention is: to overcome the problems that the existing centrifugal chemical water pumps cannot achi...
