The rotation test device is advantageous in that rotation tests of the large-scale horizontal hydro-generator in a manufacturing factory can be realized, the current is supplied to the variable frequency direct current motor by a power supply, the connection and transmission of the direct current motor are realized via the elastic coupling, and the hydro-generator rotates and generates power and drives a brushless exciter to operate so that test data can be recorded; a test platform in the factory is not needed to be destroyed so that investment is saved; the labor intensity of operation personnel is reduced, and the production efficiency is improved; besides, the installation and the operation are simple, and secondary waste is avoided.
Description
Technical field
The utility model belongs to hydrogenerator and manufactures field, particularly relates to a kind of can realization and rotate the large-size horizontal hydrogenerator rotation testing equipment of testing in manufacturing plant.
Background technology
Horizontal hydrogenerator is being manufactured after preassembly in factory, because having very large power-equipment, needs drag, the test therefore do not rotate in factory, generally need to wait until that whole unit can rotate test after the general assembly of power station, only can be to the test that rotates of the less horizontal hydrogenerator of capacity in manufacturing plant.In addition, due to the singularity of horizontal hydrogenerator support, in the time rotating test, need dig melt pit fixed base, so not only destroy the test platform in factory, increase manufacturing cost, and operation easier be large, efficiency is low.
Summary of the invention
The utility model provides a kind of can realization in manufacturing plant to rotate test, reduce manufacturing cost, be convenient to fitting operation and can improve the large-size horizontal hydrogenerator rotation testing equipment of test efficiency for solving the technical matters existing in known technology.
The technical scheme that the utility model is taked for the technical matters existing in solution known technology is:
Large-size horizontal hydrogenerator rotates testing equipment, it is characterized in that: comprise multiple basic frocks, be arranged on direct current generator and the pedestal bearing for horizontal hydrogenerator is installed and the shaft coupling being connected with horizontal hydrogenerator for direct current generator in basic frock, described pedestal bearing one side is connected with Lubricating-oil Station by pipeline, the water inlet of described Lubricating-oil Station one side and water delivering orifice are by soft pipe connection air cooler, and described air cooler connects water tank by flexible pipe.
The utility model can also adopt following technical scheme:
Described shaft coupling is spring coupling.
In described basic frock, be shaped with pickup groove and the mounting hole for direct current generator is installed.
In described basic frock, be shaped with dowel hole and the mounting hole for pedestal bearing is installed.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, can realize the rotation test of large-size horizontal hydrogenerator in manufacturing plant by this testing equipment, supply with electric current in variable ratio frequency changer direct current motor by power supply, direct current motor is by spring coupling connection for transmission, make horizontal hydrogenerator rotate generating, the running of drive brushless exciter, can record test figure.When test, without digging the fixing hydraulic generator support of melt pit and destroying shop test platform, utilize existing square chest to be processed into Special test basis frock, for increasing fixing hydrogenerator and dragging machine, not only can regulate at any time centre-height, reduce investment outlay; Alleviate operating personnel's working strength, enhance productivity.In addition, hydrogenerator is connected with cooling device by flexible pipe, and fitting operation is easy, and flexible pipe can repeatedly use, and avoids secondary waste.

In figure: 1, direct current generator; 2, shaft coupling; 3, pedestal bearing; 4, horizontal hydrogenerator; 5, basic frock; 6, pipeline; 7, Lubricating-oil Station; 8, air cooler; 9, water tank; 10, flexible pipe.
Embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1-Fig. 3, large-size horizontal hydrogenerator rotates testing equipment, comprise multiple basic frocks 5, be arranged on direct current generator 1 and the pedestal bearing 3 for horizontal hydrogenerator is installed and the shaft coupling 2 being connected with horizontal hydrogenerator 4 for direct current generator in basic frock, described pedestal bearing one side is connected with Lubricating-oil Station 7 by pipeline 6, water inlet and the water delivering orifice of described Lubricating-oil Station one side are communicated with air cooler 8 by flexible pipe 10, and described air cooler connects water tank 9 by flexible pipe 10.In the present embodiment, described Lubricating-oil Station one side arranges two air coolers 8, and described pipeline 6 comprises oil inlet pipe and flowline.
In the present embodiment, described shaft coupling is spring coupling.
In the present embodiment, in described basic frock 5, be shaped with pickup groove and the mounting hole for direct current generator is installed.
In the present embodiment, in described basic frock, be shaped with dowel hole and the mounting hole for pedestal bearing is installed.
First direct current motor 1 and horizontal hydrogenerator 4 are placed respectively in basic frock 5, and regulated both high making it in center to be consistent, and measure the beating degree of rotating shaft.After adjustment, at the both sides of hydrogenerator 4 assembling pedestal bearing 3, and the water machine end axle body of hydrogenerator 4 is connected on direct current motor 1 by shaft coupling 2.Then connect the hydraulic fluid port of pedestal bearing and Lubricating-oil Station by pipeline 6.Water inlet and water delivering orifice in Lubricating-oil Station one side are communicated with two air coolers 8 by flexible pipe 10, its objective is from water tank and draw water and lower the temperature to Lubricating-oil Station by air cooler.All appliance arrangements are connected and check errorless after, by Lubricating-oil Station standby by high pressure oil jacking device to supporting pedestal bearing 3 fuel feeding of hydraulic generator rotor, make bearing shell and rotating shaft surface of contact place form oil film, play on the one hand lubrication, jack-up rotor on the other hand, reduce friction force, can start comparatively like a cork and accelerate, reduce starting moment.Start direct current motor, by the connection for transmission of spring coupling 2, rotation hydraulic generator rotor, is opened flexible pipe 10 and air cooler 8 and is made Lubricating-oil Station cooling to rated speed by static steady raising speed.Under rated speed, horizontal hydrogenerator 4 is carried out to no-load characteristic, steady-state short-circuit test, detect bearing temperature and leakage of oil situation.Check the ruuning situation of rotating shaft one end exciter simultaneously.After being completed, cut off direct current generator 1 armature power supply, the detent of open water turbine generator 2, allows hydraulic generator rotor slowly be decelerated to and to stop, and stops the oil pump of Lubricating-oil Station.
