Abstract

The invention discloses a guide vane angle regulating device for submersible pumps, which is convenient to regulate the guide vane angle. The guide vane angle regulating device comprises a crank, a driven ring, a driving ring and a drive plate, wherein the driven ring and the driving ring are bonded and connected, one end of the crank is connected with the driven ring in a rotating mode, the other end of the crank is used for connecting and regulating the guide vane angle, a connecting mechanism for connecting the driving ring and the drive plate is arranged between the driving ring and the drive plate, and the drive plate is connected with a drive link. The guide vane angle regulating device can be used for regulating underground or underwater guide vane angle by ground operation. In the invention, by means of the triangular drive plate and a connecting link device, the guide vane can be freely driven to rotate clockwise or anticlockwise. Meanwhile, the application of the crank ensures that the guide vane angle can be greatly changed only when the driving ring and the driven ring rotate by small distance.

Description

technical field [0001] The invention relates to a guide vane angle adjustment device for a submersible pump, in particular to a guide vane angle adjustment device for a submersible axial flow pump and a mixed flow pump. Background technique [0002] Submersible shaft and mixed flow pumps have played a positive role in national production and construction since they were introduced into my country in the 1960s, and have played an active role in flood control and drainage, irrigation, industrial and mining, municipal, agricultural water supply and drainage, and sewage treatment. Due to the electromechanical integration, compact structure, small size, convenient installation, and continuous expansion of application fields, it has gradually replaced the old axial flow machine, and the power has also continued to increase. At present, the submersible pump with the largest power in my country has reached more than 1000KW. At present, my country is vigorously promoting energy savin...
