Problems solved by technology

For a full-flow turbine, since its main shaft is not directly connected to the generator, when generating electricity normally, the rotor rotates with the rotation of the turbine blades, and the torque is generated on the turbine blades connected to the rotor magnetic poles, and there is no torque on the main shaft, based on the existing The test bench cannot test the turbine blade torque

Abstract

The invention discloses a full-throughflow water turbine torque measurement device and method in the technical field of water-power engineering in order to solve the technical problem that a spindle of an existing full-throughflow water turbine is not directly connected with a power generator, torque is generated on water turbine blades connected with rotor magnetic poles during power generation,the spindle does not have torque and the torque of the water turbine blades cannot be measured based on an existing test platform. The full-throughflow water turbine torque measurement device comprises an extension shaft, a vertical shaft, a torque meter and a power measurement motor. One end of the extension shaft is axially and fixedly connected with a water turbine spindle, and the other end ofthe extension shaft extends into a water outlet channel and is in driving connection with one end of the vertical shaft perpendicularly. The other end of the vertical shaft extends out of the water outlet channel and is axially connected with the torque meter and the power measurement motor in sequence.

Description

Technical field [0001] The invention relates to a torque measuring device and method for a full tubular water turbine, belonging to the technical field of hydropower engineering equipment. Background technique [0002] In recent years, with the continuous advancement of hydropower development, the resources of medium and high head power stations have been declining. The country is increasing the development and utilization of low head and ultra-low head hydropower energy. The full tubular turbine is a horizontal axis turbine. The unit adopts a horizontal arrangement. The rotor magnetic pole of the turbine generator is directly installed on the edge of the turbine blade to seal and isolate the magnetic pole and the water flow in the flow channel to prevent leakage. The turbine blade When rotating, the generator is driven to generate electricity. Because the flow channel of the tubular turbine is linear, the water flow does not turn in the axial direction, which greatly improves t...
