Abstract
The invention relates to a drum-shaped oil tank, comprising an upper cover and a chassis, wherein the upper cover and the chassis are arranged at the upper end and the lower end of a corrugated cylinder respectively; an O-shaped sealing ring is arranged between the corrugated cylinder and the upper cover, the top face of the corrugated cylinder is provided with a sealing groove; the O-shaped sealing ring is arranged in the sealing groove. Different from the manner of arranging the sealing groove on the lower surface of the upper cover in the prior art, the butter does not need to be plastered to stick the O-shaped sealing ring after arranging the sealing groove on the upper surface of the corrugated cylinder due to the fact that the opening of the sealing groove is upwards; an oil line cannot appear between the corrugated cylinder and an adapting face of the upper cover in the process of assembling; if the oil line is arranged between the corrugated cylinder and the adapting face of the upper cover during the load test for 72 hours or the using process, the judgment of oil leakage can be made immediately.
Description
Technical field
The present invention relates to a kind of cydariform fuel tank and assembly method thereof, cydariform fuel tank and assembly method thereof in especially a kind of thrust-bearing.
Background technique
Thrust-bearing is the machine structural parts of using liquid lubricating bearing principle, and it bears whole axial loads of vertical hydrogenerator, is the parts of hydraulic turbine generator mechanical part most critical.The cydariform fuel tank is a bearing axial pushing force load, and is stressed evenly in order to guarantee thrust bearing shoe valve, and generally by the toroidal membrane supporting, each toroidal membrane links to each other with oil pipe and charges into the oil of certain pressure, utilizes the distortion of fuel tank and oil transmission to make each watt stressed evenly.
Existing cydariform Oiltank structure is as shown in Figure 1, mainly is assembled by bellows and the chassis sealing that is arranged at the loam cake of its top and is arranged at its below, O-ring seals is set between bellows and loam cake carries out airtight.
But there is following deficiency in said structure:
1, the sealed groove that is used to hold O-ring seals is arranged at the bottom surface of loam cake; Sealed groove is down uncovered when assembling; Be positioned at the easy landing of its inner O-ring seals; If be employed in the bonding O-ring seals of mode of coating butter between O-ring seals and the sealed groove; The butter of smearing is prone to be spilled over to the mating face of bellows and loam cake and on this mating face, forms oily line in assembling and the process used, be difficult to distinguish oily line and be because between loam cake and the bellows due to the leakage of oil, or bonding O-ring seals butter, increased the difficulty that seepage is judged; In addition, sealed groove is adjacent to the projection of loam cake, when operations such as processing, size check, occurs easily interfering.
2, between the end face of loam cake and bottom surface, be provided with exhaust port,, also cause its leakage because of artificial incorrect operation etc. easily even after assembling is accomplished, cram sealing.
Summary of the invention
The technical problem that the present invention solves is to overcome the above-mentioned deficiency of existing technology, provides a kind of: the cydariform fuel tank that can rapidly, accurately judge whether leakage of oil after being easy to assemble, assemble; Another object of the present invention provides the method that a kind of operation is simple and easy, need not the assembling cydariform fuel tank that assembling vacuumizes under fluid.
For solving the problems of the technologies described above, the invention provides following technological scheme:
A kind of cydariform fuel tank comprises the loam cake and the chassis of the upper/lower terminal that is arranged at bellows respectively being provided with O-ring seals between said bellows and the loam cake that the end face of said bellows is provided with sealed groove, and said O-ring seals is arranged in the sealed groove.
Adopt such structure; Be different from the existing technology mode that sealed groove is arranged on the loam cake lower surface; Through after sealed groove being opened in the upper surface of bellows; Because sealed groove is up uncovered, need not the bonding O-ring seals of coating butter separately, oily line can not occur between the fitting surface of bellows and loam cake during assembling; If oily line appears in the fitting surface of bellows and loam cake in 72 hours Load tests or using process; Can make the judgement of leakage of oil immediately, need not to distinguish this place's leakage of oil be used for the butter of bonding O-ring seals on earth, or from the fluid that the bellows inner chamber oozes out, help accurately drawing bellows and the whether airtight conclusion of loam cake assembling.In addition, when the upper surface processing sealed groove of bellows, be difficult for interfering, help the check of processing and size more.
Preferably, airtight between the end face of said loam cake and the bottom surface.Promptly cancel the end face that is arranged at loam cake in the existing structure and the exhaust port between the bottom surface, adopt after such structure, can avoid causing for misoperation or all the other factors the situation of exhaust port leakage of oil because of the people.
Preferably, the degree of depth of said sealed groove is 7.25mm～7.35mm.Adopt such structure, O-ring seals compression therein is abundant, has improved the sealability and the reliability of O-ring seals.
Preferably, the dowel screw that has been threaded on the said chassis, said dowel screw penetrates the inner chamber to bellows, and is fastening through nut between said dowel screw and the bellows.Adopt such structure, have the beneficial effect of easy accessibility.
Preferably, the upper end screw thread of said bellows is connected with tight screw, and is said tight screw that bellows and loam cake is fastening.Adopt such structure, have beneficial effect simple in structure, easy accessibility.
The assembly method of above-mentioned cydariform fuel tank may further comprise the steps:
A, install the lid and bottom dish in the top and bottom of bellows respectively, and with dowel screw and fastening tight screw, the inner chamber of bellows is through oil hole and external communications on the chassis;
B, oil hole is linked to each other with the filling gun of vacuum filling machine, the control vacuum filling machine vacuumizes and oiling to the inner chamber of bellows.
Adopt said method assembling cydariform fuel tank, have the beneficial effect that operation is few, be convenient to operate, especially be embodied in assembly manipulation and need not in fluid, to assemble, greatly reduce operation easier and improved the Security of assembling.
Preferably, said step a comprises following step:
Inject fluid in a1, the tapped hole on being arranged at the chassis;
A2, in the described tapped hole of step a1, dowel screw is installed, and the cleaning chassis surface overflow fluid;
A3, bellows are connected with dowel screw through the mounting hole of its bottom, and it is fastening that nut is installed, and are presetting in the tolerance range until the gap between the fitting surface on bellows and chassis.Adopt such method, squeeze separately more later on through fluid filling tapped hole and overflow, can avoid the air in the tapped hole after assembling, to enter in the cavity of bellows.
Preferably, said step a comprises following step:
A1, six tapped holes are set evenly circumferentially in the upper edge, chassis, and inject fluid in six tapped holes on the chassis;
A2, in the bottom of bellows along circumferentially six mounting holes being set evenly, the position of said mounting hole is corresponding one by one with the position degree of said chassis upper screwed hole, and bellows is placed the top on chassis, and each mounting hole is alignd with tapped hole one by one;
