Abstract
The utility model relates to a practical sealing device for vertical mud pumps, which is used for isolating and sealing water vapor between an impeller (8) and a bearing (18) on a main shaft of a mud pump. The utility model is provided with a special cylinder seat (5) which is provided with sealing elements (13) and (15); the sealing elements (13) and (15) can be assembled on and disassembled from the impeller (8) on the right side of a rear cover (7) following the cylinder seat (5); a transparent window (4) for observing the conditions of lubrication and sealing can be arranged near a checking bolt (14) on the outside of a grease trough (3) between the sealing elements (13) and (15) simultaneously. The utility model simplifies the processes of the checking and the repair of the sealing parts of mud pumps, and thus, the use reliability of a pump is increased.
Description
The utility model is a kind of seal arrangement, and aqueous vapor is isolated used seal arrangement in a kind of vertical blade wheel of slurry pump rotating shaft.
The water impeller of common vertical slurry pump and main shaft supporting metal roller bearing shop are provided with the water proof odour seal, and bearing end air can not enter in the pump case, the muddy water infiltration bearing that can not leak outside in the pump case.The slurry pump operating conditions is abominable, and the isolating seal device lost efficacy easily, must often in time change seal element, otherwise the decline of pump head effect, and bearing and axle wearing and tearing corrosion aggravation, the vibration noise increase, and then make the pump global failure.The seal arrangement of existing pump, or inconvenience inspection sealing situation, or inconvenience replacing seal element (need dismantle the connection of rack sleeve and pump postoperculum) cause pump to damage easily, and service work are also more numerous and diverse.
The purpose of this utility model is that a kind of practical seal arrangement will be provided, and it is changed seal element and checks that the sealing situation all should be more convenient.
The technical solution of the utility model following (component position and label thereof can contrast accompanying drawing);
Pump postoperculum seat (7) right-hand member between impeller (8) and bearing (18), be provided with one with the coaxial garden cylindrical cavity (2) of main shaft (1), the interior special-purpose garden cylinder base (5) of placing, cavity (2) left side is provided with shoulder block (16), garden cylinder base (5) and bearing (18), lining (17) are separated, garden cylinder base (5) adopts removably and bonnet (7) fixed connection, passes in and out from bonnet (7) right side during mounting or dismounting.Establish seal arrangement between garden cylinder base (5) and rotating shaft (1), adopt O type circle (13), or J type oil sealing (15), or its combination (13) (15) is a Sealing.As long as owing to be provided with special-purpose garden cylinder base (5), seal element (13) (15) can disposable dismounting, and dismounting pump case (9), impeller (8) simultaneously, and needn't dismounting bonnet (7), bearing (18) etc., the location of axle (1) also is difficult for changing.Special-purpose garden cylinder base (5) is more less, and sealed groove can accurately be made.
Compare with original vertical slurry pump sealing configuration, the Sealing of above-mentioned practical seal arrangement can intuitively simply, lightly make things convenient for the garden cylinder base from the impeller dismounting of bonnet right side.
Fig. 1 is vertical slurry pump pump head working portion and practical seal arrangement embodiment's 1 thereof a longitudinal sectional view.
Fig. 2 is the practical seal arrangement embodiment's 2 of vertical slurry pump a longitudinal sectional view.
1. main shafts, 2. garden cylindrical cavities, 3. rectangular ring grease grooves, 4. transparent close 5. special-purpose garden cylinder bases 6. attachment bolts 7. pump postoperculum seats 8. impellers 9. pump cases 10. cone screw guide grooves 11. flow guide structure 12.O type circle II 13.O type circle I 14. are checked bolt 15.J type oil sealing 16. shoulder blocks 17. linings 18. bearing 19.O type circle III among the figure.
In Fig. 1 embodiment, II type tube seat (5) is set in the bonnet (7), and fixing with bolt (6) and bonnet (7).Cylinder base (5) inner main axis (1) go up to adopt the multiple tracks combined seal structure, makes seal element with O type circle (13) and J type oil sealing (15), and two O type circles (13) are put in impeller (8) side, and one or several J type oil sealings (15) are put in bearing (18) side.Between two kinds of seal elements (13) (15) rectangle annular groove (3), filling lubrication and seal grease in the groove, groove is provided with one outward and checks a bolt (14) and a transparency window (4).On the suitable location on back cage (7) and Π type tube seat (5) mating face, should settle O RunddichtringO (12).
In Fig. 2 embodiment, garden cylinder base (5) pattern, Sealing (13) (15) compound mode, grease groove (3), check bolt (14) and fit the layout of bright window (4) identical with example 1, difference is that its O type circle (13) right side is provided with cone screw guide groove (10), is provided with O RunddichtringO (19) in the shoulder block (16).
When pump normally moves, aqueous vapor is separated by combination sealing arrangement between impeller (8) and bearing (18), as seen buy grease in the transparency window (4) clearly, if bad seals, muddy water enters grease groove (3) from O type circle (13), does not then as seen buy grease or muddy water, at this moment should in time unload pump case (9), impeller (8), garden cylinder base (5), clean back application cleaning grease, change and damaged element.Among Fig. 2 embodiment, helical guide groove (10) can reduce the erosion of silt to O type circle (13), for strengthening its effect, corresponding spiral or reinforcing plate type flow guide structure (11) can be set on impeller (8) wheel hub, and O type circle (19) can prevent J type oil sealing (15) when also damaging, or site examining and repairing when unloading garden cylinder base (5) and cleaning back cover cavity (2) muddy water enter the bearing end.
Claims (3)
1, the practical seal arrangement of vertical slurry pump, adopt O type circle (13), or J type oil sealing (15) or its combination (13) (15) are Sealing, it is characterized in that: Sealing is positioned in the garden cylinder base (5), garden cylinder base (5) then is positioned in pump postoperculum shoulder block (16) garden, the right side cylindrical cavity (2), and with removably and bonnet (7) fixed connection.
2, according to the described seal arrangement of claim 1, it is characterized in that: the outer other transparency window (4) that is provided with of bolt (14) of checking of grease groove (3) between the Sealing (13) (15).
