Description
Affiliated technical field
The utility model relates to a kind of twin-screw transfer pump, especially relates to a kind of twin-screw transfer pump bearing support.
Background technique
In oil, gas exploitation course, usually use the twin-screw transfer pump to carry undressed gassiness, wet crude, because fed sheet of a media diversity and applying working condition are abominable, cause the mechanical seal device at transmission shaft or driven shaft bearing place to damage easily, need often to change seal arrangement.At present, the sealing device structure of twin-screw transfer pump bearing support as shown in Figure 1, mechanical seal is fixed on the bearing support by setting sleeve.When mechanical seal damages, must at first remove bearing cap and locking nut, unload step again, take out bearing, bearing gasket and setting sleeve simultaneously and afterwards just can change Sealing.Need in installation process to guarantee that the inner hole of bearing seat center line overlaps just with shaft centre line can not injure mechanical seal.Because the volume of bearing support greatly and very heavy, in dismounting with very difficulty, assembly technology complexity are installed.
The model utility content
Dismounting difficulty when overcoming that mechanical seal device damages in the existing twin-screw transfer pump bearing support, deficiencies such as assembly technology complexity, the utility model provides a kind of twin-screw transfer pump bearing support.
The technological scheme that its technical problem that solves the utility model adopts is: comprise transmission shaft, bearing support, bearing cap, bearing, mechanical seal, there is bearings mounted bearing hole the bearing support outer end, and there is the closed hole that mechanical seal is installed the inner.The bearing hole of bearing support is the little step hole of outer imperial palace, and the outer surface of bearing gasket assembly matches with the bearing hole of bearing support, and the bearing gasket assembly is fixedlyed connected with bearing support; The endoporus of bearing gasket assembly is the little step hole of outer imperial palace, and Bearing Installation is in the macropore of bearing gasket assembly; The cylindrical of setting sleeve is a step surface, and setting sleeve is installed in the closed hole, and fixedlys connected with bearing support; Mechanical seal is installed in the setting sleeve endoporus, and the big end of mechanical seal is positioned at the outside of setting sleeve, fixedlys connected with setting sleeve.The hole diameter of bearing hole is greater than the outside dimension of mechanical seal.The bearing gasket assembly is composed of a fixed connection by bearing gasket and bearing housing.
The beneficial effects of the utility model are, when the mechanical seal that change to damage, need not dismantle volume greatly and very heavy bearing support, and only need elder generation to dismantle the bearing gasket assembly, taking out mechanical seal again changes, it is rational in infrastructure, process for machining and manufacturing is simple, and convenient for assembly, dismounting has reduced manufacturing and operating cost effectively.

Fig. 4 be Fig. 3 at A to view.
Among the figure: 1. transmission shaft, 2. locking nut, 3. bearing cap, 4. bearing, 5. bearing support, 6. bearing gasket assembly, 7. mechanical seal, 8. setting sleeve, 9. driven shaft, 10. bolt, 11. bearing holes, 12. closed holes, 13. oil sealing, 14. seal rings, 15. seal rings, 16. bearing gaskets, 17. bearing housings.
Embodiment
Below in conjunction with accompanying drawing 2～accompanying drawing 3 and embodiment the utility model is described further.
The utility model twin-screw transfer pump bearing support comprises transmission shaft 1, bearing support 5, bearing cap 3, bearing 4, mechanical seal 7.There is the bearing hole 11 that bearing 4 is installed bearing support 5 outer ends, and there is the closed hole 12 that mechanical seal 7 is installed the inner.
The bearing hole 11 of bearing support 5 outer ends is the little step hole of outer imperial palace, and the outer surface of bearing gasket assembly 6 matches with bearing hole 11; Bearing gasket assembly 6 endoporus are the little step hole of outer imperial palace, and bearing gasket assembly 6 is fixedlyed connected with bearing support 5.Bearing 4 is installed in the macropore of bearing gasket assembly 6.The inner ring inboard of bearing 4 is by the location of the step on the transmission shaft 1, and the outside is fixing by locking nut 2; The inboard, outer ring of bearing 4 is by location, the step hole side on the bearing gasket assembly 6, and the outside is fixing by bearing cap 3.Assembling adopts bolt that bearing cap 3, bearing gasket assembly 6 are fixedlyed connected with bearing support 5 usually for convenience.In order to reduce difficulty of processing, can be by bearing gasket 16 and the bearing housing 17 bearing gasket assembly 6 that is composed of a fixed connection.
The cylindrical of setting sleeve 8 is a step surface, and setting sleeve 8 is installed in the closed hole 12, and fixedlys connected with bearing support 5 by bolt.Mechanical seal 7 is installed in setting sleeve 8 endoporus, and the big end of mechanical seal 7 is positioned at the outside of setting sleeve 8, and fixedlys connected with setting sleeve 8.For the ease of dismounting mechanical seal 7, the hole diameter of bearing hole 11 should be greater than the outside dimension of mechanical seal 7.
Between bearing gasket assembly 6 endoporus and the transmission shaft 1 oil sealing 13 is installed; Between the endoporus of bearing gasket assembly 6 cylindricals and bearing support 5 seal ring 14 is installed; Between setting sleeve 8 cylindricals and the closed hole 12 seal ring 15 is installed.
The utility model twin-screw transfer pump bearing support is by the structure of change bearing support 5, bearing gasket assembly 6 and setting sleeve 8, and the installation direction of change mechanical seal 7, has greatly simplified mechanical seal 7 dismounting process.When needs are changed mechanical seal 7, only need to remove bolt 10, take off bearing cap 3 and locking nut 2, unload bearing gasket assembly 6 again, take out bearing 4 simultaneously, just can dismantle mechanical seals 7 then, and take out along the bearing hole 11 of axle 1 through bearing support 5 from setting sleeve 8.Owing to can under the situation of not dismounting bearing support 5, just can change mechanical seal 7, reduced labor intensity greatly, improved assembly precision.
The bearing structure at driven shaft 9 places, mechanical seal structure are identical with driving shaft 1 place.
The utility model not merely is applicable to the transmission shafts bearing of twin-screw transfer pump, also is applicable to the bearing seal of other devices.
