Abstract

The invention provides an impeller built-in electric pump adjustable blade. The impeller built-in electric pump adjustable blade comprises a blade body, wherein the angle of the blade body is adjustedthrough a lever type adjuster structure, the lever type adjuster structure comprises a control shaft arranged at the root of the blade body, the other end of the control shaft is connected with a crank, the other end of the crank is rotationally connected with one end of a connecting rod, the other end of the connecting rod is rotationally connected with an operation frame, and a dowel bar driving the operation frame to move is arranged on the operation frame. The impeller built-in electric pump adjustable blade provided by the invention is compact and simple in equipment, low in manufacturing cost and low in installation and maintenance difficulty, vibration generated when a unit is started can be effectively reduced by adjusting the angle of the blade, starting of the unit is facilitated, the requirement for traction torque can be reduced, efficient operation of electric pumps within different lift ranges can be achieved, and the drainage requirements under special conditions are met.

Description

technical field [0001] The invention relates to the technical field of electric pumps, in particular to an adjustable vane of a built-in impeller electric pump. Background technique [0002] There are many ways to adjust the vane of the electric pump. The function, system structure, cost and reliability of different adjustment methods vary greatly, and pump stations with different structural forms have different requirements for blade adjustment functions. In order to effectively adjust the operating conditions of the electric pump and keep the electric pump running in the high-efficiency zone, it is an effective means to adjust the blade angle of the electric pump. [0003] The existing electric pump blade adjustment structure is complex, resulting in high manufacturing costs of the electric pump, and difficult installation and maintenance. At the same time, during the operation of the electric pump, the existing electric pump blade adjustment structure is prone to looseni...
