According to further improvement of the utility model, the thickness of framework layer and the thickness of elastomer layer are 0.2mm.
According to further improvement of the utility model, the pad structure ringwise of obturaging is provided with a plurality of attachment holes along loop configuration.
Simultaneously, the utility model also provides a kind of survey to turn round pump, comprises the pump housing and pump cover, it is characterized in that, surveys to turn round also to comprise the above-mentioned pad of obturaging in the pump, and the pad of obturaging is arranged between the pump housing and the pump cover.
The beneficial effects of the utility model: according to the pad of obturaging of the present utility model, simple in structure, make easily, by on a skeletal structure, covering one deck elastomeric material, increase the impact resistance and the elastic strain power of gasket construction, this pad can be combined with surrounding structure better, reduce structure interval.Simultaneously, turn round pump, reduced gap between the pump housing and the pump cover, reduce lubricating oil seepage phenomenon in the pump, reduce the problem of oil pump efficient by using the above-mentioned pad of obturaging according to survey of the present utility model.
Except purpose described above, feature and advantage, the utility model also has other purpose, feature and advantage.With reference to figure, the utility model is described in further detail below.
Description of drawings
Accompanying drawing constitute this specification a part, be used for further understanding the utility model, accompanying drawing shows preferred embodiment of the present utility model, and is used for illustrating principle of the present utility model with specification.Among the figure:
Fig. 1 shows to survey in the prior art and turns round the pump structure schematic representation;
Fig. 2 shows the structural representation according to the utility model embodiment's the pad of obturaging; And
Fig. 3 shows the pad A-A that obturages among Fig. 2 to the sectional structure schematic representation.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
As Fig. 2 and shown in Figure 3, in a kind of embodiment of the present utility model, a kind of pad of obturaging comprises: framework layer 11 and elastomer layer 13, elastomer layer 13 cover on the face of framework layer 11 at least.Covering one deck elastomer layer 13 on framework layer 11 makes the pad itself of obturaging have certain elasticity, make obturage pad as survey and to turn round when using in the device that pump one class need seal, a side that has elastomer layer can produce suitable deformation, reduce and obturage pad and survey gap between the pump case of turning round pump, avoid lubricating oil seepage phenomenon in the pump, and then improve the efficient of oil pump.More preferably, elastomer layer 13 is two-layer, covers respectively on corresponding two faces of framework layer 11.At this moment, the pad 1 of will obturaging is placed on to survey and turns round when using in the pump, the both sides difference pump housing 3 and pump cover 5 connecting parts that have elastomer layer 13, gap between pad and the pump housing 3 and the pump cover 5 reduces respectively to obturage, form double sealing structure, the efficient of the oil pump of lubricating oil seepage phenomenon in the pump, and then raising so better.In the utility model, framework layer 11 preferred metal layers.More preferred layer of brass.Chalocopyrite structure is stable, and strong shock resistance can adapt to and survey the elevated pressures of turning round pump discharge.Elastomer layer 13 is preferably the nitrile butadiene rubber layer, in the specific operation process, can use the nitrile butadiene rubber plate of two kinds of different models in the both sides of framework layer 11.As using model simultaneously is that 5860 rubber plate and model are 5470 rubber plate.
In a kind of concrete mode of execution of the present utility model, the thickness of framework layer 11 is identical with the thickness of both sides elastomer layer in this pad of obturaging.Be preferably, the thickness of framework layer 11 and elastomer layer 13 is 0.2mm.The thickness of elasitic layer body 13 is too thin, the elastic strain power that produces too small, be unfavorable for reducing to survey the gap of turning round between pump middle pump body and the pump cover, and the blocked up resource of not only having wasted of the thickness of elastomer 13, improved cost, simultaneously, also increased burden for the installation of pad in device to be sealed of obturaging.
In a kind of concrete mode of execution of the present utility model, this pad structure ringwise of obturaging is provided with a plurality of attachment holes 15 along loop configuration.The device that the concrete structure of this pad of obturaging is mated use has direct relation, and the structure of the pad of obturaging as shown in Figure 2 is just in order to cooperate the survey that provides among Fig. 1 to turn round that pump use to propose.
Simultaneously, in the utility model, also provide a kind of survey to turn round pump, this survey is turned round pump and is had the structure identical with Fig. 1, comprise the pump housing 3 and pump cover 5, unlike the prior art be, turn round in this survey and used the pad of obturaging provided by the utility model in the pump, the pad 1 of obturaging is arranged between the pump housing 3 and the pump cover 5.By using the pad of obturaging provided by the utility model, the phenomenon that pump has reduced the lubricating oil leakage of oil is turned round in this survey, has improved and has surveyed the efficient of turning round pump.
According to the pad of obturaging of the present utility model, simple in structure, make easily, by on a skeletal structure, covering one deck elastomeric material, increase the impact resistance and the elastic strain power of gasket construction, this pad can be combined with surrounding structure better, reduce structure interval.Simultaneously, turn round pump, reduced gap between the pump housing and the pump cover, reduce lubricating oil seepage phenomenon in the pump, reduce the problem of oil pump efficient by using the above-mentioned pad of obturaging according to survey of the present utility model.
Be preferred embodiment of the present utility model only below, be not limited to the utility model, for a person skilled in the art, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
