Synchronous rotary blade angle adjustment device

Abstract

The invention discloses a synchronously rotating blade angle adjustment device. A main stator and an auxiliary stator are fixedly arranged on the bottom surface of the casing, and a main rotor and an auxiliary rotor matching the main stator and the auxiliary stator are fixedly arranged on the rotating shaft. The interior of the rotating shaft is provided with a hydraulic pump station and a hydraulic cylinder, the high-pressure oil port P of the hydraulic pump station communicates with the upper chamber pipeline B of the hydraulic cylinder, and the oil outlet T of the hydraulic pump station communicates with the hydraulic cylinder’s The pipeline A in the lower cavity is connected, and a controller is installed outside the casing. The controller is electrically connected to the main stator through wires, the controller is electrically connected to the auxiliary stator through wires, and the main rotor is connected to the hydraulic pressure through wires. The pump station is electrically connected, and the auxiliary rotor is electrically connected with the electromagnetic reversing valve through a wire. The rotating shaft in the present invention is installed inside the casing, and the internal and external environment isolation of the submersible motor is realized through a mechanical seal and a static seal ring, which can Use this blade angle adjustment device in any external environment.

Description

technical field [0001] The invention belongs to the technical field of submersible motors, in particular to a synchronously rotating blade angle adjusting device. Background technique [0002] In engineering applications, changing the blade angle is a way to change the performance parameters of the device. In many cases, it is not possible to stop the machine to adjust the blades, or it is inconvenient to manually adjust the blades. It is necessary to continuously adjust the blades during operation to set the parameters of the device. The blade angle automatic adjustment method is mainly divided into mechanical type and hydraulic type. When adjusting the blades during rotation, the mechanical type is prone to thrust bearing failure, and the reliability is not high; the hydraulic type is difficult to seal with high-pressure oil, and it is easy to cause oil leakage pollution. [0003] At present, there is a built-in synchronous hydraulic regulator on the market. The hydraulic...

When adjusting the blades during rotation, the mechanical type is prone to thrust bearing failure, and the reliability is not high; the hydraulic type is difficult to seal with high-pressure oil, and it is easy to cause oil leakage pollution

[0003] At present, there is a built-in synchronous hydraulic regulator on the market. The hydraulic system is built into the rotating shaft and moves with the shaft. The external brushes supply power and control commands to the hydraulic device, but it needs to stop regularly to replace the brushes. Brush use is not suitable for non-air outside environments
