Description
Technical field
The utility model relates to water power technical field of power generation, particularly relates to a kind of reliability, the Bulb Turbine Units bearing lubrication oil system that reduces water guide shoe temperature that can improve unit bearing oil fuel feeding.
Background technique
Bulb Turbine Units is due to the restriction in its pattern and space, and its bearing lubrication can only take the mode of outer circulation.Namely unit bearing oil is sent into each bearing and is set up oil film by outer power, flow to oil sump tank for after bearing lubrication and cooling, and the oil of oil sump tank sends into each bearing again after cooling, so circulates.The bearing lubrication mode of Power Plant, bearing oil pump is adopted to beat to bearing top petrol tank by oil from scavenge oil case during design, the oil of top petrol tank is by flow by gravity extremely each bearing, then the endless form of oil sump tank is concentrated to afterwards, as shown in Figure 1, comprise: scavenge oil case 1 and bearing top petrol tank 2, lubricant oil in scavenge oil case 1 is through oil pump 3, filter 4, after cooler 5, pump is to this bearing top petrol tank 2, an oil part in bearing top petrol tank 2 directly flows back to scavenge oil case 1 through spill pipe, and the oily another part in bearing top petrol tank 2 gets back to scavenge oil case 1 after relief cock 7 flows through bearing 8, design like this, when oil pump 3 quits work, bearing 8 fuel delivery will greatly reduce, after its unit operation, find to rely on the oil pressure of bearing top petrol tank 2 Gravitative Loads too low, oil flow is less than normal, especially water pilot bearing does not still reach design discharge when its fuel oil feed regulation valve standard-sized sheet, the needs of bearing lubrication and cooling cannot be met, once water guide shoe temperature was once made to reach the height of 60 DEG C.
Therefore, a kind of Bulb Turbine Units bearing lubrication oil system that can improve unit bearing lubrication oil mass, reduce water guide shoe temperature is needed badly.
Model utility content
The purpose of this utility model is to provide a kind of reliability, the Bulb Turbine Units bearing lubrication oil system that reduces water guide shoe temperature that can improve unit bearing oil fuel feeding.
To achieve these goals, the technological scheme that the utility model provides is: provide a kind of Bulb Turbine Units bearing lubrication oil system, comprise: scavenge oil case, oil pump, bearing, bearing top petrol tank, oil in described scavenge oil case is divided into two output channels after described oil pump pressurization, and Article 1 output channel is directly connected to described bearing through cooler, protective switch, alarm switch, filter screen; Article 2 output channel is connected to described bearing top petrol tank, and the outlet of described bearing top petrol tank is connected between described cooler and described protective switch, when described oil pump fuel cut-off, by described bearing top petrol tank fuel feeding.
Also spill pipe is provided with between described bearing top petrol tank and described scavenge oil case.
Described oil pump is also provided with oil pressure gage.
Also Rectifier plate is provided with between described filter screen and described bearing.
Also be provided with fuel oil feed regulation valve between described filter screen and described bearing, and the spool of described fuel oil feed regulation gate valve bores corresponding hole by uninterrupted, during operation, gate valve is arranged to closed condition.
Compared with prior art, in the utility model Bulb Turbine Units bearing lubrication oil system, because the oil in described scavenge oil case is divided into two output channels after described oil pump pressurization, Article 1 output channel is directly connected to described bearing through cooler, protective switch, alarm switch, filter screen; Article 2 output channel is connected to described bearing top petrol tank, and the outlet of described bearing top petrol tank is connected between described cooler and described protective switch, when described oil pump fuel cut-off, by described bearing top petrol tank fuel feeding.Therefore, it is possible to guarantee when described oil pump fuel cut-off, there is in described bearing top petrol tank the oil for described bearing cooling, avoid causing described bearing lack lubricant oil and be damaged, therefore, the utility model is a kind of reliability, Bulb Turbine Units bearing lubrication oil system of reducing water guide shoe temperature that can improve unit bearing oil fuel feeding.
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 the Bulb Turbine Units bearing lubrication oil system of prior art.
Fig. 2 is the schematic diagram of an embodiment of the utility model Bulb Turbine Units bearing lubrication oil system.
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 2, the Bulb Turbine Units bearing lubrication oil system 100 that the utility model embodiment provides, comprise: scavenge oil case 10, oil pump 11, bearing 12, bearing top petrol tank 13, oil in described scavenge oil case 10 is divided into two output channels after described oil pump 11 pressurizes, and Article 1 output channel is directly connected to described bearing 12 through cooler 14, protective switch 15, alarm switch 16, filter screen 17; Article 2 output channel is connected to described bearing top petrol tank 13, and the outlet of described bearing top petrol tank 13 is connected between described cooler 14 and described protective switch 15, when described oil pump 11 fuel cut-off, by described bearing top petrol tank 13 fuel feeding.
In an embodiment, between described bearing top petrol tank 13 and described scavenge oil case 10, be also provided with spill pipe 18.
In an embodiment, described oil pump 11 is also provided with oil pressure gage 110.
