Description

Be used for urgent lubricated device
Technical field
The present invention relates to a kind of being used at the device that interrupts promptly lubricating when lubricant oil is supplied with the bearing of an exhaust turbine pressure-increasing machine.
Summary of the invention
The objective of the invention is, realize a kind of like this device with a kind of simple structure, this device guarantees when interrupting the lubricant oil supply bearing to be realized enough lubricating.
Be achieved thus according to this purpose of the present invention: be provided with one vertically disposed, be connected the circulating line at least one lubricant oil service, from this circulating line below draw a conveyance conduit to the turbine engine bearing, and draw up one to the conveyance conduit of bearing of compressor and one to the reflux line that stores fuel tank, this reflux line has one for storing the through flow cross section that fuel tank always opens wide and storing the safety check that opens wide on the fuel tank backflow direction when one pressure descends in circulating line.
The invention is characterized in, do not have other moving element except a safety check.But not only when interrupting normal lubricating in short-term, realize enough lubricating for bearing; and when long-time interruption is lubricated, realize urgent lubricating by the impeller shutdown, wherein by additionally cooling off for the turbine engine bearing of violent heating from the residual amount of lubricant oil that stores fuel tank.
Store fuel tank and preferably be divided into two parts by a vertical wallboard, these two-part are in by a through flow hole and interconnect, and one lead to one the overflow pipe of the lubricant oil collecting container of exhaust lead in the part of holding reflux line.Can in the part that overflow pipe does not feed, when being full of, constitute an air cushion by separating the storage fuel tank, this air cushion is realized lubricating oil pressure and therefore guarantees when interruption is normally lubricated safety check being opened wide, and from store fuel tank lubricant oil at first is discharged in the described circulating line under pressure then.
Described overflow pipe is preferably upwards moved near the top cover place that stores fuel tank.Therefore even when storing fuel tank and be full of but when continuing normal operation, also bubble is discharged by overflow pipe as much as possible.Therefore bubble especially can not threaten urgent lubricated.
Description of drawings
The description that other features and advantages of the present invention are carried out by means of accompanying drawing by additional dependent claims with for embodiment and providing.Schematically illustrate respectively in the accompanying drawings:
Fig. 1 is according to the structure of device of the present invention,
The sectional view of Fig. 2 safety check in closed position,
The sectional view of Fig. 3 safety check in open position.
Embodiment
Be provided with two lubricant oil services 1 for device shown in Figure 1, they lead in the circulating line 2.Each of described two oil supply pipelines 1 is held a safety check 3, and this safety check forms lubricating oil stream on arrow a direction when normal supply lubricant oil.Described circulating line 2 vertically is provided with.Branch out a conveyance conduit 4 bottom at it, this conveyance conduit guiding turbine engine bearing.Another conveyance conduit 5 leads to bearing of compressor from the top of circulating line 2.Not shown in the accompanying drawings these bearings.They are positioned at the below of circulating line 2.
Branch out another reflux line 6 topmost from circulating line 2, this reflux line leads to overall storage fuel tanks with 7 expressions that are arranged on circulating line 2 tops.In reflux line 6, install one totally with 8 safety check of representing.Shown in Fig. 2 and 3, this safety check has a valve disc 9, and it is guiding in vertical direction with moving freely.In valve body 10, be provided with the lath 11 of a plurality of L shaped structures for this reason.The through flow cross section 12 of a circle hole shape that always opens wide is set in valve disc 9.What also can select is that this through flow cross section is constituted by the bypass duct of a cross-over connection safety check 8.This through flow cross section 12 is dimensionally much smaller than the cross section of reflux line 6.
Described storage fuel tank 7 is by vertical wallboard 13 separated into two parts 14,15.Base plate 16 tops that abut against storage fuel tank 7 are in a through flow hole 17 are set in the wallboard 13.An overflow pipe 18 is advanced by leaps and bounds and is stored in the part 14 of fuel tank 7 in addition, upwards moves near top cover 19 places that store fuel tank 7 always.The other end of overflow pipe 18 is passed in the lubricant oil collecting container 20, and this collecting container is by pipeline 21 exhausts.The dividing plate of a definite current drainage cross section 22 is installed on the upper end of overflow pipe 18.In the size of this through flow cross section 12 greater than current drainage cross section 22.Abutting against the place, base plate 16 tops that stores fuel tank 7 joins a circular hole 23 in the reflux line 6.
When lubricant oil is supplied with connection, then lubricant oil is transported to circulating line 2, and is transported to bearing by conveyance conduit 4,5 from this circulating line by oil supply pipeline 1 and unlimited then safety check 3.By reflux line 6 and always unlimited through flow cross section 12 lubricant oil is entered into simultaneously and store fuel tank 7.Improve the lubricated oil level that stores in the fuel tank 7 thus.When this lubricated oil level improved, compression was arranged in the air of part 15 after part 14 is full of fully.The air that is arranged in part 14 is discharged by overflow pipe 18.If lubricated oil level reaches the upper end of overflow pipe 18, then a part of lubricant oil flows out by this overflow pipe.But because the current drainage cross section 22 of this pipeline less than the through flow cross section 12 of safety check, therefore makes part 14 utilize the lubricant oil that is positioned under the pressure to be full of fully.Also compress the air that is arranged in this part top at this by the lubricant oil that through flow hole 17 enters into part 15.As shown in Figure 2, during this process the valve disc 9 of safety check 8 by being in during lubricating oil pressure on its bottom surface is maintained in its closed position.
When the lubricant oil supply was interrupted in short-term, safety check 3 cut out.The pressure of circulating line 2 and reflux line 6 bottoms is descended.But owing to store in the top part that air cushion in the part 15 of fuel tank 7 makes reflux line 6, and the end face of valve disc 9 be under the pressure effect, in the position that provides once more in Fig. 3, valve disc leans on part L shaped below the lath 11 this pressure in this position with the valve disc roof pressure.Safety check 8 is opened wide and can make lubricant oil on arrow b direction, enter in the circulating line 2 and and then enter in conveyance conduit 4 and 5 by reflux line 6.Guarantee thus when interrupting by oil supply pipeline 1 supplying lubricating oil in short-term, to be lubricated for described bearing.
If this lubricant oil is supplied with and do not worked, then motor and turbine pressure-increasing machine were just shut down after several seconds.After this can be emptied completely and store fuel tank 7.Substantially go up by gravity flow to the minimum point of circulating line and flow to the turbine engine bearing by conveyance conduit 4 therefrom at this lubricant oil, this turbine engine bearing has the higher heat load of ratio piston compressor bearing.When storing fuel tank 7 emptyings end, lubricant oil only flows out by circular hole 23 and flows to the turbine engine bearing and cool off this bearing by circulating line 2 and conveyance conduit 4.
When application was of the present invention, described storage fuel tank 7 can be set directly at the top of the housing of exhaust turbine pressure-increasing machine.This can make reflux line 6 and overflow pipe 18 shorten pipe range and realize compact structure thus.
