Description
Technical field
The utility model relates to nitrocotton and drives sour apparatus field, especially a kind ofly centrifugally drives sour machine pusher spindle nose and hollow shaft head anticorrosion structure.
Background technology
Nitrocotton drives the centrifugal of sour technique employing and drives sour machine, wherein pusher shaft and hollow shaft all adopt carbon steel to make, because having a large amount of nitration mixture and acid fume to cause corrosion to the pusher shaft of centrifuge and position, hollow shaft front end driving in sour process, directly affect centrifuge service life, thus cause pusher shaft and hollow shaft service life is short, repair rate is high, also have impact on centrifugal normal production of driving sour machine.
Utility model content
Technical problem to be solved in the utility model is to provide that a kind of effective raising is centrifugal drives sour machine pusher spindle nose and hollow shaft head is corrosion-resistant and the centrifugal of anti-wear performance drives sour machine pusher spindle nose and hollow shaft head anticorrosion structure.
The utility model solves the technical scheme that its technical problem adopts: centrifugally drive sour machine pusher spindle nose and hollow shaft head anticorrosion structure, comprise hollow shaft and be slidably socketed on the pusher shaft in the chute in hollow shaft, the hollow shaft head skin of described hollow shaft is provided with hollow shaft head corrosion-inhibiting coating, the pusher spindle nose skin of pusher shaft is provided with pusher spindle nose corrosion-inhibiting coating, and the skin that push rod is pressing close to the first end of pusher shaft of pusher shaft is provided with push rod corrosion-inhibiting coating.
Further, the range of coat thicknesses of described hollow shaft head corrosion-inhibiting coating, pusher spindle nose corrosion-inhibiting coating and push rod corrosion-inhibiting coating is for being more than or equal to 1 millimeter.
Further, described hollow shaft head corrosion-inhibiting coating is C4 steel heap welding coat.
Further, described pusher spindle nose corrosion-inhibiting coating is C4 steel heap welding coat.
Further, described push rod corrosion-inhibiting coating is C4 steel heap welding coat.
The beneficial effects of the utility model are: when reality uses, and because the utility model has been set up being the most easily corroded in actual production and the protection of abrading section, thus improve the life-span of this device greatly.Concretely, that the hollow shaft head skin of hollow shaft is provided with hollow shaft head corrosion-inhibiting coating, the outer skin that push rod is pressing close to the first end of pusher shaft being provided with pusher spindle nose corrosion-inhibiting coating and pusher shaft of pusher spindle nose of pusher shaft is provided with push rod corrosion-inhibiting coating, general, in conjunction with the experience of practice, can preferred hollow shaft head corrosion-inhibiting coating, pusher spindle nose corrosion-inhibiting coating and push rod corrosion-inhibiting coating are all designed to C4 steel heap welding coat, so not only simplify production technology, also best anticorrosion and anti-wear performance can be had, the utility model is particularly useful for using in the comparatively serious environment of nitrocotton acidizing corrosion.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Be labeled as in figure: hollow shaft 1, chute 11, hollow shaft head 12, hollow shaft head corrosion-inhibiting coating 121, pusher shaft 2, push rod 21, push rod corrosion-inhibiting coating 211, pusher spindle nose 22, pusher spindle nose corrosion-inhibiting coating 221.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As shown in Figure 1 centrifugal drives sour machine pusher spindle nose and hollow shaft head anticorrosion structure, comprise hollow shaft 1 and be slidably socketed on the pusher shaft 2 in the chute 11 in hollow shaft 1, hollow shaft head 12 skin of described hollow shaft 1 is provided with hollow shaft head corrosion-inhibiting coating 121, pusher spindle nose 22 skin of pusher shaft 2 is provided with pusher spindle nose corrosion-inhibiting coating 221, and the skin that push rod 21 is pressing close to pusher spindle nose 22 one end of pusher shaft 2 is provided with push rod corrosion-inhibiting coating 211.
Generally add man-hour actual, need first preliminary working in advance, that then carries out corrosion-inhibiting coating at turning position arranges technique.As the sour environment of nitrocotton, generally most preferably utilize built-up welding C4 steel coating to realize protecting, namely select hollow shaft head corrosion-inhibiting coating 121, push rod corrosion-inhibiting coating 211 and pusher spindle nose corrosion-inhibiting coating 221 to be all set to C4 steel heap welding coat.Not only ensure that corrosion-resistant and wear-resisting performance, also simplify manufacturing process greatly.
Further say, when carrying out built-up welding C4 steel, general selection adopts C4 steel welding rod to carry out, and first carries out preheating before namely needing built-up welding with acetylene torch.In addition, each built-up welding thickness should be controlled within 1mm during built-up welding, after integral surface built-up welding reaches 1mm, carry out the built-up welding of second layer 1mm again, 3mm is reached with this overlay cladding thickness that circulates, last, after the operations such as polishing, the overlay cladding thickness making 3mm thick reduces and ensures that coating final thickness scope is for being more than or equal to 1 millimeter.General, the range of coat thicknesses of described hollow shaft head corrosion-inhibiting coating 121, pusher spindle nose corrosion-inhibiting coating 221 and push rod corrosion-inhibiting coating 211 is for being more than or equal to 1 millimeter for best.When built-up welding, also should be noted that weld deposit process will prevent the generation of built-up welding crackle.After built-up welding completes, only need through carrying out the mechanical processing techniques such as rough turn and fine grinding to meet the requirement of surface of the work precision.
The utility model not only increases the corrosion resistance of pusher spindle nose 22 and hollow shaft head 12, and improve wearability and the intensity of surface of the work, extend the service life of centrifuge pusher shaft 2 and hollow shaft 1, reduce operating cost, there is very wide marketing prospect.
