Description
Technical field:
The utility model relates to pump field, and in particular to open surface seal structure in a kind of double entry pump.
Background technique:
The large-scale double entry pump of our companies production is widely used in the Yellow River and irrigates by lifting water to a higher level with a water pump, etc. industry, due in the medium pumped containing a large amount of
Silt, the flow passage parts such as impeller, sealing ring quick abrasion, service life are low, and each filling season will open pump cover and be overhauled, overcurrent
Part needs regularly more bring the normal operation for meeting system.The maintenance of large-scale double entry pump carries out at the scene, after opening pump cover, in
It opens the fish paper on face and is typically necessary and re-replace, face area is big and bolt arrangement compares due to opening in large-scale double entry pump
More, processing fish paper is particularly troublesome, and dismounting is also very inconvenient, time-consuming.
Utility model content:
The technical problem to be solved by the utility model is to provide surface seal structure is opened in a kind of double entry pump, one kind is provided
Securely and reliably, flexible structure it is simple, it is convenient for disassembly and assembly in open surface seal structure to adapt to the installation of large-scale double entry pump.
The following technical solution is employed for technical problem to be solved in the utility model to realize: opening face in a kind of double entry pump
Sealing structure, including the pump housing and pump cover, the pump housing top and the bottom of pump cover are fixedly connected to connection edge sealing, the pump housing
The interior survey of upper surface of connection edge sealing offer O-ring slot, O shape sealing strip is connected in the inner cavity of the O-ring slot, it is described
Offer several location holes on the connection edge sealing of the pump housing and pump cover, the connection edge sealing of the pump housing and pump cover is by stud through fixed
Position hole is fixedly connected.
Preferably, the stud uses hexagonal header stud.
Preferably, face above and below the connection edge sealing for connecting edge sealing and pump cover of the pump housing.
Preferably, O shape sealing strip is fitted closely with O-ring slot.
Working principle of the utility model is: the application, which mainly opens in the pump housing, processes O-ring slot on face, then install additional
O shape item, closes pump cover, load onto open all studs on face, under the action of pump cover gravity and stud fastening force, by similar
The sealing principle of O-ring, to play good sealing function.
The beneficial effects of the utility model are: may know that by the structure of description above and its sealing surface, such form peace
Dress is very simple and convenient, and sealing effect is good, convenient to overhaul.But when should be noted that installation, O shape item is sealed by face is opened in the pump housing
The trend of slot is slowly pressed in slot with hand, is sure not to hurt O shape surface, in order to avoid influence sealing effect.
Detailed description of the invention:
Fig. 1 is the structural schematic diagram in the utility model；
Fig. 2 is the enlarged drawing in the utility model in Fig. 1；
Fig. 3 is the partial top view of the utility model middle pump body；
Wherein: 1 pump housing, 2 pump covers, 3 O-ring slots, 4 O shape sealing strips, 5 studs, 6 location holes, 7 connection edge sealing.
Specific embodiment:
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
Face combines and is specifically illustrating, and the utility model is further described.
Embodiment: as shown in Figure 1-3, surface seal structure is opened in a kind of double entry pump, including the pump housing 1 and pump cover 2, the pump housing
1 top is fixedly connected to the bottom of pump cover 2 connect edge sealing 7, the connection edge sealing of the connection edge sealing 7 and pump cover 2 of the pump housing 1
The interior survey of about 7 faces, the upper surface of the connection edge sealing 7 of the pump housing 1 offers O-ring slot 3, the inner cavity of the O-ring slot 3
In be connected with O shape sealing strip 4, O shape sealing strip 4 is fitted closely with O-ring slot 3, the pump housing 1 on the connection edge sealing 7 of pump cover 2
Several location holes 6 are offered, the pump housing 1 is fixedly connected by stud 5 through location hole 6 with the connection edge sealing 7 of pump cover 2, institute
It states stud 5 and uses hexagonal header stud.
The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.Current row
The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also
It will have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention.The utility model
Claimed range is defined by the appending claims and its equivalent thereof.
