Abstract
The utility model discloses a kind of bearing oil feed pipe road systems of bulb turbine hydropower station.It is DN250~DN300 for adding a fuel feeding general pipeline, fuel feeding general pipeline caliber between oil inlet pipe in top petrol tank and each bearing.The effect of fuel feeding general pipeline is: being carried out flowing pressure stabilizing with oil to the bearing that top petrol tank oil-feed port comes out, solves the difficulty of current-regulating voltage-regulating, it is ensured that each branch pipe inner bearing fuel feeding oil pressure is stable, fuel supply flow rate abundance is constant, to guarantee the safe and stable operation of unit.The utility model design scheme is simple and clear, economical and practical.
Description
Technical field
The utility model relates to bearing oil feed pipe roads, especially a kind of bulb turbine hydropower station bearing oil feed pipe road system
System.
Background technique
Currently, domestic existing bulb turbine hydropower station bearing oil supply system is 1 fuel feeding for coming out top petrol tank
Pipeline is directly divided into 4 for oil inlet pipe, lacks current-regulating voltage-regulating device in system, whole system by all valves, oil pipe line, from
Bearing fuel feeding task at 4 is completed in matching to dynamicization element etc. jointly.When equipment or matching link that a certain branch pipe occur goes wrong,
The bearing of a certain branch pipe with oil mass increase or reduce deviate design value when, can to other bearings for oil inlet pipe cause compared with
Great fluctuation process, thus cause other bearing fuel feeding oil pressure, flow it is unstable.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of bulb turbine hydropower station bearing oil feed pipe road system
System solves the oil pressure of each bearing fuel feeding of bulb tubular hydraulic generating set, the instability problem of flow.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of bulb turbine hydropower station bearing supplies
Oil pipe line system, including top petrol tank, water pilot bearing are reversely supplied for oil inlet pipe, combination bearing forward direction for oil inlet pipe, combination bearing
Oil inlet pipe, combination bearing are radial for oil inlet pipe, each bearing of unit, in top petrol tank and each bearing for adding one between oil inlet pipe
Fuel feeding general pipeline, fuel feeding general pipeline caliber are DN250~DN300mm.
The utility model has the beneficial effects that can effectively solve the oil of each bearing oil of bulb tubular hydraulic generating set
Pressure, instability of flow problem, guarantee the safe and stable operation of unit.
Detailed description of the invention
Fig. 1 is the bulb turbine hydropower station bearing oil feed pipe road system schematic of the utility model.
In figure:
1 --- oil feed line of the top petrol tank to fuel feeding general pipeline
2 --- fuel feeding general pipeline
3 --- water pilot bearing is for oil inlet pipe
4 --- combination bearing is reversely for oil inlet pipe
5 --- combination bearing forward direction is for oil inlet pipe
6 --- combination bearing is radial for oil inlet pipe
7 --- top petrol tank
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description:
As shown in Figure 1, the bulb turbine hydropower station bearing oil feed pipe road system of the utility model, including top petrol tank 7,
Water pilot bearing is reversely radially supplied for oil inlet pipe 4, combination bearing forward direction for oil inlet pipe 5, combination bearing for oil inlet pipe 3, combination bearing
Each bearing of oil inlet pipe 6, unit, in top petrol tank 7 and each bearing for adding a fuel feeding general pipeline 2, fuel feeding general pipeline between oil inlet pipe
Caliber is DN250~DN300mm.
The bearing that top petrol tank comes out first is supplied to caliber to the oil feed line 1 of fuel feeding general pipeline through top petrol tank with oil
The fuel feeding general pipeline 2 of DN250~DN300 carries out bearing with oil by the general pipeline to flow pressure stabilizing, then be supplied again by water pilot bearing
Oil inlet pipe, combination bearing are reversely given for oil inlet pipe, combination bearing radial direction for oil inlet pipe for oil inlet pipe, combination bearing forward direction each respectively
Bearing oil system fuel feeding.Valve and Automation Elements are indicated for the box on oil inlet pipe etc. in figure.
The effect of fuel feeding general pipeline is: being carried out flowing pressure stabilizing with oil to the bearing that top petrol tank oil-feed port comes out, be solved
The difficulty of current-regulating voltage-regulating, it is ensured that each branch pipe inner bearing fuel feeding oil pressure is stable, fuel supply flow rate abundance is constant, to guarantee the safety of unit
Stable operation.
Embodiment described above is merely to illustrate the technical idea and feature of the utility model, and its object is to make ability
Technical staff in domain, cannot be only practical to limit with the present embodiment it will be appreciated that the content of the utility model and implement accordingly
Novel the scope of the patents, i.e., same changes or modifications made by the revealed spirit of all the utility model, it is practical new still to fall in this
In the scope of the patents of type.
