For solving the problems of the technologies described above, the technical solution of the utility model is: provide a kind of turbo-engine lube apical axis cranking system jacking(oil) pump interim oil supplying device, comprise main fuel tank and jacking(oil) pump, described main fuel tank is connected with jacking(oil) pump; The female pipe of the backflow of the recyclable oil of described apical axis cranking system tool, the female pipe of described backflow is connected with main fuel tank; Wherein, the female pipe of described backflow seals when main fuel tank is rebuild with the main fuel tank connection; Described interim oil supplying device comprises that substituting main fuel tank comes the collecting system oil return and to the interim fuel tank of jacking(oil) pump fuel feeding, be connected with oil return pipeline and oil supply line on the described interim fuel tank; Described female pipe that refluxes is connected with the oil return pipeline of interim fuel tank, is connected with first valve on the oil return pipeline; Described oil supply line is connected with jacking(oil) pump, is connected with the 3rd valve on oil supply line.
Compared with prior art, the interim oil supplying device of above-mentioned model utility turbo-engine lube apical axis cranking system jacking(oil) pump at main fuel tank because emptying is overhauled or during anticorrosion need to repair, oil sources can be provided temporarily, the assurance jacking(oil) pump can be used, when making the main fuel tank maintenance, system is unlikely to pause, and has solved the inconvenience that produces when lubricant oil main fuel tank that the overhaul duration brings is isolated maintenance.
[description of drawings]
Fig. 1 is the schematic representation of the utility model one preferred embodiment.
[embodiment]
In order to make technical problem to be solved in the utility model, technological scheme and beneficial effect clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
See also Fig. 1, it is a preferred embodiment of the interim oil supplying device of the utility model turbo-engine lube apical axis cranking system jacking(oil) pump, described turbo-engine lube apical axis cranking system comprises main fuel tank 1 and jacking(oil) pump 2, main fuel tank 1 and jacking(oil) pump 2 are connected, and described main fuel tank 1 provides the oil return of lubricant oil and reclaiming system for jacking(oil) pump 2.When main fuel tank 1 overhauls, then can not give jacking(oil) pump 2 fuel feeding, can be contained in interim oil supplying device on the turbo-engine lube apical axis cranking system this moment, substitutes that main fuel tank 1 comes the collecting system oil return and to jacking(oil) pump 2 fuel feeding.Described interim oil supplying device is connected with jacking(oil) pump 2, gives jacking(oil) pump 2 fuel feeding, and is moving with the normal disk of keeping rotor, and the oil return of reclaiming system.Described interim oil supplying device volume is little, easily dismounting.Described apical axis cranking system self has female pipe 4 that refluxes.
Described interim oil supplying device comprises interim fuel tank 3, is connected with oil return pipeline 30, repairing pipeline 32, oil supply line 34 and delivery pipeline 36 on the interim fuel tank 3.Described interim fuel tank 3 all draws back interim fuel tank 3 with the oil return of turbo-engine lube apical axis cranking system by female pipe 4 that refluxes by oil return pipeline 30 and repairing pipeline 32, lubricant oil is provided for jacking(oil) pump 2 by oil supply line 34, by delivery pipeline 36 with the oily emptying in the interim fuel tank 3.
When main fuel tank 1 did not overhaul, the female pipe of the backflow of described turbo-engine lube apical axis cranking system 4 was connected with main fuel tank 1, in the oil return inflow main fuel tank 1 with system.When main fuel tank 1 overhauls,, prevent that oil from flowing in the main fuel tank 1 with female pipe 4 and the mouth of pipe of main fuel tank 1 connection special-purpose closure plate 6 of oil return and the sealing of air bag (not shown) of refluxing.Oily emptying in the main fuel tank 1, the special-purpose closure plate 6 of oil return installed in the female pipe 4 of oil return and fixing, note not damaging the anticorrosive coat of the female pipe 4 of oil return and main fuel tank 1, give airbag aeration, check that the female pipe 4 of air bag and oil return fits tightly, make the female pipe of backflow 4 mouths of pipe that are connected with main fuel tank 1 seal fully.
The female pipe 4 of the backflow of system is connected by the oil return pipeline 30 of flexible pipe 5 with interim fuel tank 3, is connected with first valve 300 and pneumatic pump (not shown) on oil return pipeline 30, and the oil return in the female pipe 4 of described backflow is by in the pneumatic pump suction oil return pipeline 30.Be connected with flexible pipe 5 between described oil return pipeline 30 and the repairing pipeline 32, between oil return pipeline 30 and repairing pipeline 32, be connected with second valve 320 and pump (not shown), by pump with in the oily suction repairing pipeline 32 in the oil return pipeline 30, and by in the interim fuel tank 3 of repairing pipeline 32 inflows.Because on the overhaul of steam turbine platform that interim fuel tank 3 often perches,, then oil return can not be introduced in the interim fuel tank 3 if oil return pipeline 30 directly is connected with interim fuel tank 3.
Described interim fuel tank 3 is equipped with a plurality of the 3rd valves 340 with the joint of oil supply line 34 and the joint of oil supply line 34 and jacking(oil) pump 2, opens the 3rd valve 340, and interim fuel tank 3 can move for the rotor normal disk jacking(oil) pump 2 fuel feeding.Can be connected by flexible pipe 5 between described oil supply line 34 and the interim fuel tank 3.
Be provided with the 4th valve 360 between described delivery pipeline 36 and the interim fuel tank 3, after main fuel tank 1 has overhauled, open the 4th valve 360, oil in the interim fuel tank 3 is empty by delivery pipeline 36 streams, can pull down interim oil supplying device this moment from system, reuse the backflow that main fuel tank 1 is given jacking(oil) pump 2 fuel feeding and reclaiming system.Can be connected by flexible pipe 5 between described delivery pipeline 36 and the interim fuel tank 3.
The interim oil supplying device of above-mentioned turbo-engine lube apical axis cranking system jacking(oil) pump at main fuel tank 1 since emptying overhaul or be anticorrosion when needing to repair, can provide interim oil sources by interim oil supplying device, the assurance jacking(oil) pump can be used, when making main fuel tank 1 maintenance, system is unlikely to pause, and has solved the inconvenience that produces when lubricant oil main fuel tank 1 that the overhaul duration brings is isolated maintenance.Treat that main fuel tank 1 can begin to remove to interim fuel tank 3 oil extractions and from system when jacking(oil) pump 2 fuel feeding.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
