Description
Technical field:
Originally practical to be related to huge vertical hydrogenerator thrust bearing deflector device
Background technique:
The capacity of huge vertical hydropower generator is big, rotatable parts weight are also very big, leads to entire thrust bearing
Thrust loading is more much larger than conventional power unit, and frictional dissipation when thrust bearing works also can be higher than conventional power unit, this is just to pushing away
More stringent requirements are proposed for lubricating oil cooling system in power bearing.And often due to zero in structure limitation and thrust bearing oil groove
Number of packages amount is more, causes the lubricating oil oil stream disorder in oil groove, and cold oil can not effectively flow through the working face of thrust bearing, Jin Erying
Cooling effect has been rung, has caused Thrust-vectoring nozzle higher, has brought security risk to unit operation.This requires us to push away not changing
The flow path for optimizing lubricating oil oil stream under the premise of power bearing overall structure as far as possible, allows more cold oil that can flow through thrust axis
Near the working face held, to achieve the purpose that preferably to reduce Thrust-vectoring nozzle.
Summary of the invention:
The purpose of this utility model is to disclose a kind of huge vertical hydrogenerator thrust bearing deflector device, Ke Yiyou
Effect ground improves flow path of the lubricating oil in unit thrust bearing oil groove, and it is attached that guidance lubricating oil flows through thrust bearing segment working face
Closely, bearing lubrication cooling effect is improved.
The technical solution of the utility model are as follows: by flow guide plate body (1), right lock piece (2), left side locking plate (3),
One bolt (4), the second bolt (5), third bolt (6), the 4th bolt (7), holding screw (8) composition, holding screw (8) are screwed into
In the screw hole of card slot (10) slot bottom of thrust bearing shoe valve (9) side, as Horizontal limiting, flow guide plate body (1) is with mounting ring side
Initial position is steadily pushed into the gap location between two pieces of thrust bearing shoe valves (9), until being blocked by holding screw (8), right lock
Piece (2), left side locking plate (3) are withstood flow guide plate body (1) from outside, and the first bolt (4), the second bolt (5) are by right lock
For piece (2) fastening on thrust bearing shoe valve (9), third bolt (6), the 4th bolt (7) are pushing away left side locking plate (3) fastening
In power watt (9), formed fixed whole.
The flow guide plate body (1) is that sheet metal is bent, and there are the mounting ring (11) of hollow round, top in front end
There are right side wing plate (12), the left side wing plate (13) with thrust bearing shoe valve (9) side card slot (10) cooperation in two sides respectively.
The right side wing plate (12) and left side wing plate (13) of the flow guide plate body (1) during installation, with thrust bearing shoe valve (9)
Card slot (10) slot bottom, there are gaps for upper surface.
Technical effect:
1. hot oil area and cold oil can be effectively isolated in the utility model when the operation of turbine-generator units nominal situation
Area, when the cold oil in thrust bearing oil sump forms oil stream flowing under the rotational agitation of rotatable parts, the utility model is pushed away at every two pieces
It is provided with running boundary for cold oil oil stream between power watt, it is attached that guidance cold oil oil stream flows through thrust bearing segment working face to the maximum extent
Closely, bearing lubrication cooling effect is improved.
2. all very convenient, installing and dismounting whole process solderless termination process, it is only necessary to pass through is replaced in the utility model installation maintenance, maintenance
That unlocks bolt can be completed conjunction disassembly, and the design of the mounting ring of flow guide plate body front end has fully considered ergonomics,
Operation maintenance personnel can be completed the push-in of deflector and be exited with a hand.
3. the card slot of the right side wing plate of flow guide plate body, left side wing plate and thrust bearing shoe valve side cooperates, with card slot slot bottom, on
There are gaps on surface, while guiding oil stream, do not interfere with micro swing of the thrust bearing segment in unit operation, right
Unit safety operation is without influence.

Specific embodiment:
As shown in Figure 1 and Figure 2, a kind of huge vertical hydrogenerator thrust bearing deflector device, by flow guide plate body 1,
Right lock piece 2, left side locking plate 3, the first bolt 4, the second bolt 5, third bolt 6, the 4th bolt 7,8 groups of holding screw
At holding screw 8 being screwed into the screw hole of 10 slot bottom of card slot of 9 side of thrust bearing shoe valve, as Horizontal limiting, then by deflector sheet
Body 1 is steadily pushed into the gap location between two pieces of thrust bearing shoe valves 9 using mounting ring side as initial position, until being blocked by holding screw 8
Until, then with right lock piece 2, left side locking plate 3 flow guide plate body is blocked from outside, and use the first bolt 4, the second bolt
