Description
Technical field
The utility model relates to a kind of testing device, especially relates to the testing device of a kind of horizontal hydrogenerator.
Background technology
Test run refers to that machine etc. is assembling after well, and before formal use, test run, sees whether its performance satisfies the criteria.
Hydrogenerator refers to be that water can be converted into the generator of electric energy by primover taking water turbine. Current, through water turbine, can convert water to mechanical energy, and the rotating shaft of water turbine drives again the rotor of generator, converts mechanical energy to electric energy and exports. It it is the main dynamics equipment that power station produces electric energy. Hydrogenerator can be divided into vertical and horizontal two classes by axial location. Big-and-middle-sized unit generally adopts vertical, and horizontal layout is generally used for small unit and bulb-type tubular hydro set.
In prior art, horizontal hydrogenerator, especially usually there is a difficult problem for test run difficulty in large-size horizontal hydrogenerator, has the defect such as energy consumption height, safe reliability difference.
Practical novel content
In order to overcome the deficiency that prior art exists, the utility model provides the testing device of a kind of energy-conservation, safe and reliable horizontal hydrogenerator.
The testing device of a kind of horizontal hydrogenerator, described device comprises pull-over gear, change speed gear box, transverse bearing, generator body, radial turbine bearing, described generator body comprises shaft coupling, the speed end of change speed gear box is connected with the shaft coupling of generator body, the low speed end of change speed gear box is connected with pull-over gear, and the center axis of described pull-over gear, change speed gear box, shaft coupling is consistent; Described transverse bearing is arranged between change speed gear box and generator body, and transverse bearing is arranged on the first bearing support; The generator body the other end is connected with radial turbine bearing, and radial turbine bearing is arranged on two bearing bracket; Described pull-over gear, the first bearing support, two bearing bracket all pad certain altitude by under bearing.
As preferably, being connected by transition disc between described shaft coupling and change speed gear box.
As preferably, it is 420mm by the height of pad under bearing.
As preferably, described bearing comprises the flat board of 300mm and the pole boots of 120mm.
As preferably, described change speed gear box is equipped with a set of outer circulation oil supply system.
The utility model structure is simple, and reasonable in design, the utility model is more energy-conservation, reliably safer; The utility model is particularly useful for the hypervelocity test run of large-size horizontal turbine-generator units, and application geartransmission principle drags the hypervelocity test run of large-size horizontal unit, efficiently solves a large-size horizontal hydrogenerator test run difficult problem.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
