Background
The oil seal device of the lubricating oil is a mechanical part used for sealing the lubricating oil, the oil seal is that the vulnerable parts in the centrifugal pump are replaced more frequently, in the prior art, the oil seal of the centrifugal pump generally adopts an O-shaped seal ring, A, because the contact surface of the O-shaped seal ring and the seal is an arc surface, therefore, the sealing contact area is small, the sealing effect is poor, a plurality of groups of O-shaped sealing rings are required to be applied at the same time, and the service life is short, and the O-shaped sealing rings need to be replaced periodically, B, when the O-shaped sealing rings are replaced, not only a plurality of groups of O-shaped sealing rings need to be replaced simultaneously, but also the shaft coupling in the centrifugal pump needs to be disassembled to be replaced, and after the detached coupler is installed again, the centrifugal pump can be safely applied after being subjected to re-centering adjustment, so that the trouble of time and labor waste and long shutdown and maintenance time caused by oil seal replacement is solved.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model discloses a main aim at provides a dislocation is to open oil seal for centrifugal pump, through this technical scheme, two are to open oil seal body and two are to opening oil blanket skeleton and constitute jointly, not only install and change the convenience, have shortened the change time greatly to effectual sealed effect and the life who improves the oil blanket.
In order to achieve the above purpose, the technical solution of the present invention is realized as follows: the utility model provides a centrifugal pump is with dislocation is to open oil seal, includes the oil blanket body, the oil blanket body is made by elastic material, still includes the oil blanket skeleton, the oil blanket skeleton is made by rigid metal material, the oil blanket body is two half circular arcs of bisecting, is provided with the skeleton groove that is the T font between two half circular arc oil blanket outer circular arc surfaces and interior circular arc surfaces, the cross-section of oil blanket skeleton is two half circular arcs of bisecting of T font, and two half circular arc oil blanket skeletons of bisecting are inserted respectively in the skeleton groove on the oil blanket body that corresponds.
As a further technical scheme, the two half-arc oil seal frameworks are respectively inserted into the framework grooves of the two corresponding half-arc oil seal bodies in a staggered mode, so that one end of one half-arc oil seal framework is inserted into the framework groove of the other half-arc oil seal body in a staggered mode.
As a further technical scheme, the section surfaces of the two split semi-circular arc oil seal bodies and the two split semi-circular arc oil seal frameworks are relatively complementarily inclined.
As a further technical scheme, the oil seal device further comprises a positioning convex edge and a positioning groove, wherein the positioning convex edge and the positioning groove are respectively arranged on the section of the split semi-arc oil seal framework.
The beneficial effect after adopting above-mentioned technical scheme is: the utility model provides a dislocation is to open oil seal for centrifugal pump, through this technical scheme, makes two open oil seal circles realize dismantling the concatenation through the oil blanket skeleton, and the person of facilitating the use splices two half oil seal circles fast, and the person of facilitating the use also just can change oil seal circle under the shaft coupling prerequisite not taking apart, and not only the installation is changed conveniently, has shortened the change time greatly to effectual sealed effect and the life who improves the oil blanket.
