Description
Technical field
This utility model relates to a kind of deep well pump integrated mechanical sealing, belongs to technical field of mechanical.
Background technology
As it is shown in figure 1, existing borehole shaft driven (centrifugal) pump uses packing seal, the axle if the tension of packing seal pressure can wear and tear, if
That presses is the most loose, does not has sealing function, and filler needs periodic replacement, very inconvenient；It addition, filler select improper, fill out
It is the shortest that material gland malcompression, filler are too thin, filler is cut etc. all can cause seepage, does not has sealing function.
Utility model content
In view of the foregoing, the purpose of this utility model is to provide a kind of deep well pump integrated mechanical sealing, installs
Convenient, fast, seal reliable.
For achieving the above object, this utility model is by the following technical solutions:
A kind of deep well pump integrated mechanical sealing, including drive sleeve, sealing gasket, axle sleeve, bearing body, bearing, seal,
Moving sealing ring,
Being arranged with bearing body, bearing, seal, moving sealing ring on this axle sleeve, this axle sleeve upper end connects this sealing gasket, this biography
Dynamic set is connected by the first connecting bolt is fixing with sealing gasket, axle sleeve upper end.
Further,
It is provided with O-ring seals between described axle sleeve and power transmission shaft, between described seal and axle sleeve, is provided with the first axle gear
Circle, is provided with the second shaft block ring between described moving sealing ring and axle sleeve.
The described seal position corresponding with on bearing body has the detection hole run through.
Described drive sleeve is provided with confinement bolt.
Described bearing body and seal connect by the second connecting bolt is fixing,
Described bearing body is connected by the 3rd connecting bolt is fixing with pump seat, the excircle of described seal and this pump seat
Endoporus closely cooperates.
Connect on described bearing body and have the hexagon socket head cap screw that can move along pump seat direction.
The utility model has the advantage of:
Deep well pump integrated mechanical sealing of the present utility model, installs and easy maintenance, seals reliable；Assemble in advance,
Checking and the black box of test, assembling quality is more easy to ensure；There is less coefficient of friction, can use longevity of effective extending shaft
Life.
Accompanying drawing explanation
Fig. 1 is existing deep well pump packing seal structure schematic diagram.
Fig. 2 is the structural representation of deep well pump integrated mechanical sealing of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is described in further detail.
As in figure 2 it is shown, deep well pump integrated mechanical sealing disclosed in this utility model, including drive sleeve 2, sealing gasket 3,
Axle sleeve 5, bearing body 6, bearing 8, seal 10, moving sealing ring 11, axle sleeve 5 is arranged with bearing body 6, bearing 8, seal 10,
Moving sealing ring 11, axle sleeve 5 upper end connects sealing gasket 3, and drive sleeve 2 and sealing gasket 3, axle sleeve 5 upper end are by hexagon socket head cap screw 13
Fixing connection；
Bearing body 6 and seal 10 connect by four hexagon socket head cap screws 15 are fixing, and bearing body 6 and pump seat are long by four
Circular hole bolt is fixed and is connected and whole mechanical seal be fixed on pump seat, and the excircle of seal 10 is closely joined with pump seat endoporus
Close, prevent the local outflow that water contacts with pump seat from bearing body 6.
It is provided with O-ring seals 4 between axle sleeve 5 and power transmission shaft 1, between seal 10 and axle sleeve 5, is provided with the first shaft block ring
9, it is provided with the second shaft block ring 12 between moving sealing ring 11 and axle sleeve 5.
Seal 10 position corresponding with on bearing body 6 has the detection hole 14 run through, for detecting whether there are current
Go out, to change out of order mechanical seal in time.
Drive sleeve 2 is provided with confinement bolt, can be fixed together with drive sleeve 2 by power transmission shaft 1, and power transmission shaft 1 runs up
Time, drive sleeve 2, sealing gasket 3, axle sleeve 5 run up therewith.
For ease of changing fault mechanical seal, the opposite sides of bearing body 6 connects two hexagon socket head cap screws 7, changing machine
When tool seals, first being pulled down by four slotted hole bolts, then twist hexagon socket head cap screw 7 to pump seat direction, mechanical seal is by upwards
Power and readily accessible.
During installation, being first integrally attached on pump seat by integrated mechanical sealing, by drive sleeve 2, sealing gasket 3 and O shape seals
Circle 4 is pulled down, and after power transmission shaft 1 installs, installs O-ring seals 4, sealing gasket 3, drive sleeve 2, the taboo in locking drive sleeve 2 successively
Plug with molten metal bolt, i.e. complete the installation process of integrated mechanical sealing.Easy for installation, quick；The sealing assembling in advance, check and testing
Assembly, assembling quality is more easy to ensure, has less coefficient of friction, can service life of effective extending shaft.
The above is preferred embodiment of the present utility model and the know-why used thereof, for the technology of this area
For personnel, in the case of without departing substantially from spirit and scope of the present utility model, any based on technical solutions of the utility model base
Equivalent transformation on plinth, simple replacement etc. obviously change, within belonging to this utility model protection domain.
