What I mentioned above is just the Francis type. For Francis turbines, in addition to these, there are also water diversion elbows, tailrace elbows, sometimes air supply devices, telescopic tubes, small units and flywheels. inertia, a cooling system, a lubrication system. , etc. For units above 1000 kW, the flywheel is on the motor.
For impact turbines and oblique impact turbines, they mainly include: impeller, main shaft, bearings and bearing seats, water spray elbow (containing: l 'spray needle, spray needle rod, nozzle, etc.), machine seat, water diversion elbow, telescopic pipe, etc.
For flow turbines axial, it mainly involves: channel chamber, channel, bearing box, main shaft, flywheel, machi coverne, water guide bearing and some guide bearings, etc.
