Abstract
A hermetically-sealed construction between PA6 diesel engine air cooler and its bearing, the gasket seal comprising air cooler and air cooler bearing and be folded between the sealing surface of described air cooler and the sealing surface of air cooler bearing, sealing pad is made up of rubbery cork.The utility model eliminates the seal groove of original structure, have employed the plane sealing structure directly installing gasket seal between air cooler and air cooler bearing, improve the sealing between air cooler and air cooler bearing, ensure that the reliability of sealing, avoid in seal groove generation ponding occurring and causes the phenomenon of corrosion and the abnormal fracture of attachment bolt, the utility model is applicable to PA6 diesel engine simultaneously.
Description
Technical field
The utility model relates to a kind of hermetically-sealed construction of diesel engine, is specifically related to the hermetically-sealed construction between a kind of PA6 diesel engine air cooler and its bearing, belongs to Marine Diesels field.
Background technology
PA6 diesel engine widely uses with boats and ships, power station, nuclear power emergency set, and incorporated by reference to consulting Fig. 1 and Fig. 2, the air cooler 1 of PA6 diesel engine is arranged on air cooler bearing 2 by bolt, and the top of this air cooler 1 is provided with scavenging air box 3.Between air cooler 1 and air cooler bearing 2, generally take seal approach, the sealing surface between PA6 diesel engine air cooler bearing 2 and air cooler 1 is rectangle, and size is about 1840mm × 570mm, and seal f ace width is about 45mm; Fig. 2 is shown in by existing hermetically-sealed construction, arranging two seal grooves 21 respectively near main engine power output and free end, installed sealing strip 4 in sealing groove 21.But be through Practice Survey to find, adopt the phenomenon that between the PA6 diesel engine air cooler of above-mentioned encapsulation scheme and air cooler bearing, sealing surface leaks to happen occasionally, also find that there is the problems such as seal groove 21 corrosion, attachment bolt fracture simultaneously.
Analysis for above-mentioned phenomenon shows, the reason causing the problem can not guaranteeing to seal to occur is, the width of the sealing surface of air cooler 1 is too narrow, thus cannot cover the seal groove 21 on air cooler bearing 2 completely, and therefore the sealing strip 4 of this place installation is inoperative; , can not be covered by air cooler 1 sealing surface completely just because of seal groove 21 meanwhile, therefore can produce ponding in seal groove 21, thus cause seal groove 21 that corrosion situation occurs; In addition, because the sealing surface between air cooler 1 with air cooler bearing 2 directly contacts, therefore, when air cooler 1 and air cooler bearing 2 be heated deform time, its distortion can to connecting bolt produce thermal stress, even cause bolt fracture.
Utility model content
Technical problem to be solved in the utility model is, overcome the deficiency that between existing PA6 diesel engine air cooler and air cooler bearing, hermetically-sealed construction exists, hermetically-sealed construction between a kind of PA6 diesel engine air cooler and its bearing is provided, solve that sealing surface leaks, seal groove corrosion and attachment bolt are subject to the problem that fracture occurs thermal stress, ensure sealing good between air cooler and air cooler bearing and reliability thereof.
The utility model solves the technical scheme that its technical problem adopts:
Hermetically-sealed construction between a kind of PA6 diesel engine air cooler and its bearing, comprise air cooler and air cooler bearing, it is characterized in that: described hermetically-sealed construction also comprises the gasket seal between sealing surface and the sealing surface of air cooler bearing being folded in described air cooler, and sealing pad is made up of rubbery cork.
Further, the width of described gasket seal is identical with the width of the sealing surface of described air cooler, and the thickness of sealing pad is 3mm.
Further, a layer sealing agent is provided with between the sealing surface of described air cooler bearing and described gasket seal and between the sealing surface of described air cooler and described gasket seal.
Further, described sealant is 596 sealants.
Compared with prior art, the beneficial effects of the utility model are:
(1) have employed the plane sealing structure directly installing gasket seal between air cooler and air cooler bearing, the material of sealing pad meets EN14R standard, quality is soft, ensure that the laminating of the sealing surface of itself and air cooler and air cooler bearing, prevents the leakage of liquid; Also be coated with sealant between sealing surface simultaneously, further improve the sealing between air cooler and air cooler bearing; In addition sealing pad has good toughness, avoids the risk occurring quick-fried, ensure that the reliability of sealing.
(2) the utility model eliminates the seal groove of original structure, thus avoids in seal groove phenomenon ponding occurring and causes corrosion.
(3) gasket seal have employed rubbery cork material, can absorb the thermal stress from coupling components, thus avoids the generation of the abnormal fracture of attachment bolt.

Fig. 1 is the schematic diagram of air cooler and air cooler bearing.
Fig. 2 is existing Packed structural representation.
Fig. 3 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the hermetically-sealed construction between PA6 diesel engine air cooler described in the utility model and its bearing is described in further detail, but protection domain of the present utility model should not be limited with this.
Refer to Fig. 3, the hermetically-sealed construction of diagram PA6 diesel engine air cooler and its bearing comprises air cooler 1, air cooler bearing 2 and gasket seal 5.Between the sealing surface 11 that described gasket seal 5 is folded in described air cooler 1 and the sealing surface 22 of air cooler bearing 2, sealing pad 5 is made up of the rubbery cork meeting EN14R standard, its width is identical with the width of the sealing surface 11 of described air cooler 1, and thickness is 3mm.Be provided with a layer sealing agent between the sealing surface 22 of described air cooler bearing 2 and described gasket seal 5, be also provided with a layer sealing agent between the sealing surface 11 of described air cooler 1 and described gasket seal 5, described sealant is 596 sealants.
The utility model when mounted, first on the sealing surface 22 of air cooler bearing 2, be coated with last layer 596 sealant equably, then gasket seal 5 is installed according to the position of fastening bolt holes, then be also coated with last layer 596 sealant equably in the upper plane of gasket seal 5, lift air cooler 1 afterwards and be seated on air cooler bearing 2.
