Description
Technical field
The utility model relates to turbine technology field, particularly relates to a kind of top guide bearing assembly structure extending bearing shell working life, guarantee hydraulic turbine operation safety.
Background technique
In water turbine, because runner static unbalance can produce radial centrifugal force, because the cavity cavitation erosion in draft tube can produce horizontal pulsating force, radial water thrust can be produced because blade opening is uneven and gap of seal ring is uneven.The Main Function of turbine guide bearing bears the radial force and runout power that are transmitted by axle, with fixing unit axial location, ensures that axle center is stablized.Guide bearing is the important component part of water turbine, and its workmanship directly affects the operation of water turbine, and in the middle of operation, common fault is bearing running hot, and time serious, bearing shell can be burned.
Therefore, a kind of top guide bearing assembly structure extending bearing shell working life, guarantee hydraulic turbine operation safety is needed badly.
Model utility content
The purpose of this utility model is to provide a kind of top guide bearing assembly structure extending bearing shell working life, guarantee hydraulic turbine operation safety.
To achieve these goals, the technological scheme that the utility model provides is: provide a kind of top guide bearing assembly structure, comprise: guide shoe, insulating pad, shaft current detection plate, supporting member, support bolt and locking nut, described guide shoe tiling is arc structure, and described arc structure is designed to and slide rotor decentraction structure, described guide shoe and slide rotor is made to form a gap, the described guide shoe back side arranges described shaft current detection plate, described guide shoe is fixed on described insulating pad, described supporting member side is fixedly connected with described insulating pad, opposite side caves inward formation ball recess, described support bolt one end is set as the spherical structure coordinated with described ball recess, the other end and described locking nut screw-thread fit.
Described supporting member and described insulating pad are bolted fixing.
Described guide shoe is sector structure, and the arc length of described guide shoe tiling is less than the arc length at the described guide shoe back side, and described guide shoe quantity one has 12 pieces.
The tiling of described guide shoe is provided with babbit layer.
Described shaft current detection plate is also connected with ammeter by wire.
Also comprise temperature detecting resistance, described guide shoe is provided with temperature measuring hole, and the lighting outlet of described temperature detecting resistance is inserted in described temperature measuring hole, and built-in turbine oil in described temperature measuring hole.
Compared with prior art, due in the utility model top guide bearing assembly structure, owing to being provided with described insulating pad and shaft current detection plate, can prevent shaft current from producing to greatest extent, shaft current can be detected in time, in order to avoid cause unnecessary loss simultaneously.
By following description also by reference to the accompanying drawings, the utility model will become more clear, and these accompanying drawings are for explaining embodiment of the present utility model.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of an embodiment of the utility model top guide bearing assembly structure.
Embodiment
With reference now to accompanying drawing, describe embodiment of the present utility model, element numbers similar in accompanying drawing represents similar element.As mentioned above, as shown in Figure 1, the top guide bearing assembly structure 100 that the utility model embodiment provides, comprise: guide shoe 1, insulating pad 2, shaft current detects with plate 3, supporting member 4, support bolt 5 and locking nut 6, described guide shoe 1 tiling is arc structure, and described arc structure is designed to and slide rotor decentraction structure, described guide shoe 1 is made to form a gap with slide rotor, this gap is convenient to allow turbine oil enter, guide shoe 1 is cooled, described guide shoe 1 back side arranges described shaft current detection plate 3, described guide shoe 1 is fixed on described insulating pad 2, described supporting member 4 side is fixedly connected with described insulating pad 2, opposite side caves inward formation ball recess, described support bolt 5 one end is set as the spherical structure coordinated with described ball recess, the other end and described locking nut 6 screw-thread fit.
In an embodiment, described supporting member 4 is bolted fixing with described insulating pad 2.
In an embodiment, described guide shoe 1 is in sector structure, and the arc length of described guide shoe 1 tiling is less than the arc length at described guide shoe 1 back side, and the quantity one of described guide shoe 1 has 12 pieces.
In an embodiment, the tiling of described guide shoe 1 is provided with babbit layer.
In an embodiment, described shaft current detection plate 3 is also connected with ammeter by wire.
In an embodiment, also comprise temperature detecting resistance (figure does not show), described guide shoe 1 is provided with temperature measuring hole, and the lighting outlet of described temperature detecting resistance is inserted in described temperature measuring hole, and injects turbine oil in described temperature measuring hole.
Compared with prior art, composition graphs 1, due at the utility model top guide bearing assembly structure 100, owing to being provided with described insulating pad 2 and shaft current detection plate 3, can prevent shaft current from producing to greatest extent, shaft current can be detected in time, in order to avoid cause unnecessary loss simultaneously.
Above disclosedly be only preferred embodiment of the present utility model, certainly can not limit the interest field of the utility model with this, therefore according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
