Abstract

The invention relates to a closed impeller capable of being adjusted in multiple modes. The closed impeller comprises a connecting base and a front cover plate which are used for forming a closed impeller body; guide vane devices used for adjusting the size of an inner cavity of the closed impeller are arranged between the connecting base and the front cover plate at equal intervals; adjusting devices used for adjusting the size of the guide vane devices are arranged on the outer sides of the guide vane devices; each guide vane device comprises a connecting shaft used for connecting the connecting base and the front cover plate, a fixed vane, a movable vane and a pin column; the movable vanes are embedded in the fixed vanes, and the front ends of the fixed vanes are connected with the connecting shafts; the front ends of the movable vanes are rotationally connected with the connecting shafts; and the pin columns are fixed to the two ends of the outer side of each fixed vane. The closed impeller has the beneficial effects that independent machining and overall assembly structural design are adopted, the manufacturing difficulty is low, the assembly precision is controllable, follow-up maintenance and repair are convenient, the size of a discharging inner cavity of the impeller is adjustable, and the liquid outlet amount and the liquid outlet speed are controlled.

Description

technical field [0001] The invention relates to the technical field of impellers, in particular to a multi-adjustable closed impeller. Background technique [0002] The closed impeller is composed of blades and front and rear cover plates. The closed impeller has high efficiency and is difficult to manufacture. It is widely used in centrifugal pumps and is suitable for transporting clear water, solutions and other cleaning products with low viscosity and no particles. liquid. [0003] The traditional closed impeller mainly adopts the overall structure of integral casting, which is difficult to manufacture, has low precision, cannot adjust the discharge volume, and has poor flexibility in use. In addition, if part of the structure of the impeller is damaged, the entire impeller will fail. Contents of the invention [0004] The object of the present invention is to provide a multi-adjustable closed impeller to solve the problems raised in the above-mentioned background tech...
