Abstract
The utility model provides an emergent oil supply unit of no powered, relates to an emergent oil supply unit of no powered. The utility model discloses a solve currently when all breaking down for the power of steam turbine axle bush fuel feeding and emergency power source, can't carry out the fuel feeding for the steam turbine axle bush, and cause the problem that the steam turbine axle bush burns out. An emergent oil supply unit of no powered includes emergent oil feeding reservoir, normally open valve, normal close valve, an oil pipe, the 2nd oil pipe, walks the gentle valve that moves of trachea, the lower extreme of the emergent oil feeding reservoir of is provided with the normally open valve through an oil pipe and steam turbine axle bush oil feeding system intercommunication on the oil pipe, and an oil pipe is provided with the normal close valve through the 2nd oil pipe and oil feeding reservoir intercommunication on the 2nd oil pipe, and the upper end of emergent oil feeding reservoir is through walking trachea and compressed air source intercommunication, walks and is provided with pneumatic valve on the trachea. The utility model is used for the steam turbine field.
Description
Technical field
The utility model relates to a kind of oil supplying device, is specifically related to a kind of unpowered type and meets an urgent need oil supplying device.
Background technique
During rotary machine running; lubricant oil is needed to lubricate; otherwise cannot run; lubricant oil needed for general lubrication is transported to by oil pump the position needing lubrication; large-size steam turbine causes bearing shell to damage for preventing unexpected forced outage; be provided with a set of standby battery emergency power supply, supply emergency oil pumping source guarantees that forced outage gear pump can also continue, to turbine bearing pad fuel feeding a period of time, then to shut down.Because emergency power supply is seldom used, at ordinary times to the fault being difficult to during emergent battery feed maintenance maintenance find that some are hidden, often can have an accident so be in operation, after having a power failure, emergency power supply cannot start and causes turbine bearing pad to burn major accident.
Model utility content
The utility model is solve existing power supply for turbine bearing pad fuel feeding and emergency power supply when all breaking down, and cannot carry out fuel feeding for turbine bearing pad, and the problem causing turbine bearing pad to burn, and then proposes a kind of unpowered type and to meet an urgent need oil supplying device.
The utility model is the technological scheme taked that solves the problem: a kind of unpowered type oil supplying device of meeting an urgent need comprises emergent oil feeding reservoirs, normally open valve, normal close valve, the first oil pipe, the second oil pipe, walks the gentle movable valve of tracheae, the lower end of emergent oil feeding reservoirs is communicated with turbine bearing pad oil supply system by the first oil pipe, first oil pipe is provided with normally open valve, first oil pipe is communicated with oil feeding reservoirs by the second oil pipe, second oil pipe is provided with normal close valve, the upper end of emergent oil feeding reservoirs is passed through to walk tracheae and is communicated with compressed gas source, walks on tracheae and is provided with pneumatic valve.
The beneficial effects of the utility model are: the utility model structure is simple, by arranging emergent oil feeding reservoirs above steam turbine oil supply system, and the first oil pipe between emergent oil feeding reservoirs and turbine bearing pad arranges normally open valve, the second oil pipe between emergent oil feeding reservoirs and former oil feeding reservoirs arranges normal close valve, compressed gas source is utilized to provide power for emergent oil feeding reservoirs, and emergent oil feeding reservoirs with pass through to walk tracheae between compressed gas source and be communicated with, walk on tracheae and be provided with pneumatic valve, when the power supply of turbine bearing pad fuel feeding and emergency power supply all break down, normal close valve cuts out, normally open valve is opened, pneumatic valve is opened, oil in emergent oil feeding reservoirs is that turbine bearing pad carries out fuel feeding by the first oil pipe under the effect of compressed gas source, do not need to use electric power, when the power-off of steam turbine oil supply system, ensure that the fuel feeding of turbine bearing pad, avoid turbine bearing pad by the generation of burn observations.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment one: composition graphs 1 illustrates present embodiment, the oil supplying device of meeting an urgent need of a kind of unpowered type described in present embodiment comprises emergent oil feeding reservoirs 1, normally open valve 2, normal close valve 3, first oil pipe 4, second oil pipe 5, walk tracheae 7 and pneumatic valve 8, the lower end of emergent oil feeding reservoirs 1 is communicated with turbine bearing pad oil supply system by the first oil pipe 4, first oil pipe 4 is provided with normally open valve 2, first oil pipe 4 is communicated with oil feeding reservoirs 6 by the second oil pipe 5, second oil pipe 5 is provided with normal close valve 3, the upper end of emergent oil feeding reservoirs 1 is passed through to walk tracheae 7 and is communicated with compressed gas source, walk on tracheae 7 and be provided with pneumatic valve 8.
In the utility model, normally open valve 2 is in the state of closedown when having electric, be in the state of unlatching in the event of a power failure; Normal close valve 3 is in the state of unlatching when having electric, be in the state of closedown in the event of a power failure.Therefore, when the power supply of turbine bearing pad fuel feeding and emergency power supply all break down, normal close valve 3 cuts out, and normally open valve 2 is opened, and pneumatic valve 8 is opened, the oil in emergent oil feeding reservoirs 1 under the effect of compressed gas source by the first oil pipe 4 for turbine bearing pad carries out fuel feeding.
Embodiment two: composition graphs 1 illustrates present embodiment, described in present embodiment, the volume of emergent oil feeding reservoirs 1 is 40m
3.Setting like this, enough turbine bearing pad Emergency uses.Other compositions are identical with embodiment one with annexation.
Embodiment three: composition graphs 1 illustrates present embodiment, the pressure of compressed gas source described in present embodiment is 4 ~ 8 ㎏.Setting like this, the pressure of compressed gas source is set to 4 ~ 8 ㎏, ensures that the pressure in emergent oil feeding reservoirs 1 is identical with the pressure of compressed gas source.Other compositions are identical with embodiment one or two with annexation.
Working principle
When the power supply of turbine bearing pad fuel feeding and emergency power supply all break down, normal close valve 3 cuts out, and normally open valve 2 is opened, and pneumatic valve 8 is opened, the oil in emergent oil feeding reservoirs 1 under the effect of compressed gas source by the first oil pipe 4 for turbine bearing pad carries out fuel feeding.
