Abstract
The utility model relates to a connecting structure of an oil receptacle oil pipe and a main shaft operating oil pipe, which comprises an oil receptacle inner oil pipe, an oil receptacle outer oil pipe and a main shaft operating oil pipe. The connecting flange of the oil receptacle inner oil pipe is provided with counter bores, the oil receptacle inner oil pipe is connected with the main shaft operating oil pipe into a whole through counter bores and bolts, and the connecting flange of the oil receptacle outer oil pipe is connected with the connecting flange of the oil receptacle inner oil pipe through bolts. The utility model has the advantages that not only concentricity and installation precision of the main shaft operating oil pipe, the oil receptacle outer oil pipe and the oil receptacle inner oil pipe are guaranteed through adopting such a structure, and installation labor hour is shortened, but also the service life of a hydraulic turbine generating unit is prolonged so as to ensure safe and reliable operation.
Description
Technical field
The utility model belongs to tubular turbine and makes the field, particularly relates to the linkage structure of a kind of lubricant receiver oil pipe and main shaft operating oil line.
Background technique
At present, the opening and closing of tubular turbine blade all are will to be communicated with the inside and outside chamber of main shaft operating oil line from two oil pipes (oil-feed each other and oil return) of speed regulator main control valve by lubricant receiver, constitute the oil system that the operation runner bucket rotates.Lubricant receiver generally is installed in the generator bubble head, is connected with the current collection annulate shaft with generator stand.The existing to-and-fro motion in unit operation of main shaft operating oil line rotatablely moves simultaneously in addition, because operating oil line length is longer, be approximately more than the 7m, so lubricant receiver operating oil line installation precision directly influences the installation quality and the working life of unit.The operating oil line of existing structure lubricant receiver and main shaft operating oil line be connected to the main shaft operating oil line and lubricant receiver inner oil tube, outer oil pipe link together by bolt-through, look for concentricity and throw at clipping room, but when lubricant receiver is connected with operating oil line, because reasons in structure, there is an operating oil line to need to disintegrate earlier, after installing, need to carry out the secondary centering, so that the concentricity of maintenance main shaft operating oil line and lubricant receiver inner oil tube, outer oil pipe.If above-mentionedly manage respectively that decentraction can cause then that the lubricant receiver bearing shell grinds watt, motion hair fastener and operating oil line two chambeies scurry the wet goods problem.In addition, this linkage structure can not satisfy installation precision, but also has increased installation time and difficulty.
Summary of the invention
The utility model provides a kind of guarantee to install concentricity and precision, the lubricant receiver oil pipe of raising work efficiency and the linkage structure of main shaft operating oil line for solving the technical problem that exists in the known technology.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is: the linkage structure of lubricant receiver oil pipe and main shaft operating oil line, comprise lubricant receiver inner oil tube, the outer oil pipe of lubricant receiver and main shaft operating oil line, it is characterized in that: be shaped on counterbore on the described lubricant receiver inner oil tube adpting flange, the lubricant receiver inner oil tube links into an integrated entity by counterbore and bolt and main shaft operating oil line, and the outer oil pipe adpting flange of lubricant receiver is connected linkage structure with formation lubricant receiver oil pipe and main shaft operating oil line by bolt with lubricant receiver inner oil tube adpting flange.
The utility model can also adopt following technological scheme:
Evenly be shaped on four counterbores on the described lubricant receiver inner oil tube adpting flange.
Advantage and the good effect that the utlity model has are: because the utility model is shaped on counterbore on lubricant receiver inner oil tube adpting flange, earlier the lubricant receiver inner oil tube is linked into an integrated entity by counterbore and bolt and main shaft operating oil line, and then the outer oil pipe adpting flange of lubricant receiver is connected with lubricant receiver inner oil tube adpting flange by bolt, by adopting said structure, not only guarantee the concentricity and the installation precision of the outer oil pipe of main shaft operating oil line, lubricant receiver inner oil tube and lubricant receiver, and shortened installation work-hour; Also can prolong the working life of hydraulic turbine generator unit simultaneously, make it safe and reliable to operation.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, the outer oil pipe of lubricant receiver; 2, lubricant receiver inner oil tube; 3, counterbore; 4, main shaft operating oil line; 5, bolt; 6, bolt.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, the linkage structure of lubricant receiver oil pipe and main shaft operating oil line, comprise lubricant receiver inner oil tube 2, the outer oil pipe 1 of lubricant receiver and main shaft operating oil line 4, evenly be shaped on four counterbores 3 on described lubricant receiver inner oil tube 2 adpting flanges, the lubricant receiver inner oil tube links into an integrated entity with main shaft operating oil line 4 by counterbore 3 and bolt 5, and, need not behind the centering to disintegrate to two pipe adjusting concentricity and throws.Outer oil pipe 1 adpting flange of lubricant receiver directly is connected with lubricant receiver inner oil tube adpting flange to constitute the linkage structure of lubricant receiver oil pipe and main shaft operating oil line by bolt 6, can solve secondary disintegration problem behind the main shaft operating oil line centering like this, guarantee the concentricity and the installation precision of main shaft operating oil line and the inside and outside oil pipe of lubricant receiver, and improved installation efficiency.
