Technical field
This utility model relates to the bearing fueller of a kind of sliding bearing, particularly relates to one and is applied to vertical water turbine and sends out
In motor, the combination bearing fueller of runner-plate pump band pressure-oil tank, belong to oil supply system field.
Background technology
Thrust bearing is the vitals in generating set, is mainly used to support the axial load of unit tumbler.Thrust
Being thrust bearing shoe valve in order to support axial load in bearing, the upper surface of thrust bearing shoe valve coordinates with tumbler runner plate, and lower surface is by bearing
Supporting structure supports.During work, the runner plate of rotation drives cold lubricating oil to enter the gap between thrust bearing shoe valve and runner plate and forms dynamic pressure
Oil film, dynamic pressure oil film simultaneously with the work surface generation heat exchange of thrust bearing shoe valve and runner plate, take away heat.
In prior art, the lubrication oil supply mode of thrust bearing mainly uses immersion lubrication or DFF Direct Fuel Feed lubrication.
Wherein: soak lubrication and refer to inject in oil groove in advance lubricating oil, make thrust bearing shoe valve be immersed in lubricating oil.Work
Time, runner plate rotates, and drives lubricating oil to form oil film wedge between runner plate and thrust bearing shoe valve.But in actual use, due to thrust
Watt and runner plate be all immersed in lubricating oil, and oil body is relatively big, and this results in unit when high-speed cruising, can produce very
The big additional oil that stirs is lost, thus reduces generator operation efficiency.
DFF Direct Fuel Feed lubrication refers to arrange nozzle in the oil inlet side of thrust bearing shoe valve or set out oil groove on thrust bearing shoe valve, makes cold profit
Lubricating oil is directly entered thrust bearing shoe valve work surface.General lubrication oil circulation circuit is as follows: cold lubricating oil enters from the oil inlet side of thrust bearing shoe valve
Enter tiling and form wedge-shaped oil film, subsequently become deep fat and flow into oil groove around from the gap between tiling and runner plate, then by high pressure
Deep fat is extracted into oil cooler cooling from oil groove and becomes cold oil by oil pump, and the oil groove finally offered from nozzle or thrust bearing shoe valve enters again
Enter thrust bearing shoe valve.But in actual use, when high-pressure oil pump breaks down out of service, the failure of oil feed of thrust bearing shoe valve, will
Causing the support losing oil film between thrust bearing shoe valve and runner plate, the friction between thrust bearing shoe valve and runner plate becomes dry friction, easily occurs
Tile kilning phenomenon, the safety in utilization of thrust bearing is low.
It addition, number of patent application is the Chinese invention patent of CN201210455364.X, it discloses a kind of hydraulic generator
