Description
Technical field
The utility model relates to a kind of mechanical seal device, particularly a kind ofly avoids outside mud to enter box house, prevents the seal arrangement of the Rotary table for drilling machine that box house lubricant oil throws away.
Background technique
Rig generally is used for geologic prospecting, creeps into to underground by driving drilling tool, obtains the machinery of geologic information in kind.The rig top rotary table adopts the labyrinth seal form more at present; when high speed operation; in gear housing appears in regular meeting, suck mud or throw away lubricated oil condition; cause lubricant oil early failue in the casing; gear and bearing loss; and throw away lubricant oil environment is polluted, thereby limited the application of rotary disk driller in high drilling speed zone.
When rig rotates, because the coaxiality deviation of labyrinth seal causes the clearance volume of same position constantly to change easily, thereby causes the variation of seal clearance internal air pressure, cause certain pumping action (pump suction phenomenon).Rotary speed is more high, and coaxiality deviation is more big, and this pumping action is more obvious, and pumping action acquires a certain degree, drive the lubricant oil that has got rid of in outside mud and inside and cross labyrinth seal, cause seal failure, thereby mud enters, pollute casing, lubricant oil throws away, befouling environment.
The model utility content
The utility model technical issues that need to address provide a kind of avoiding because the rotating disk seal failure of rig causes the Rotary table for drilling machine seal arrangement that sucks mud in the gear housing or throw away lubricant oil.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of Rotary table for drilling machine seal arrangement, comprise the gear that is arranged in the casing, described gear top arranges the solid of rotation that rotates synchronously with gear, the upper end of solid of rotation fixedly installs the mud umbrella that covers gear and casing, described mud umbrella outer rim arranges corresponding first convex edge of stretching out outside casing downwards, the corresponding casing outer side wall of mud umbrella place arranges second convex edge of stretching out downwards, the corresponding box inside of mud umbrella arranges the 3rd convex edge of stretching out downwards, the length of described second convex edge is greater than the length of first convex edge and the 3rd convex edge, overhead gage between first convex edge and the 3rd convex edge is set on the described casing, the circumferentially some discharge orifices that are positioned at the casing outside of overhead gage, on being set with, the overhead gage outside stretches into the sealing plate between first convex edge and second convex edge, fixedly install an end between second convex edge and the solid of rotation and set up sealing flange in the overhead gage upper-end surface, one end of the corresponding overhead gage of described sealing flange upwards stretches between second convex edge and the 3rd convex edge, and an end of the corresponding solid of rotation of sealing flange upwards stretches between the 3rd convex edge and the solid of rotation and is provided with to the hamulus of the 3rd convex edge inflection.
Further improvement of the utility model is: the horizontal position that described sealing flange arranges an end of hamulus is higher than the horizontal position of sealing plate upper end.
Further improvement of the utility model is: described the 3rd convex edge correspondence is arranged on the Gear Root inboard.
Further improvement of the utility model is: between described solid of rotation and the mud umbrella two seals circle is set, described sealing flange arranges seal ring between overhead gage.
Further improvement of the utility model is: described mud pack is drawn together the straightway that cooperates with solid of rotation and inclined downward section laterally.
Owing to adopted technique scheme, the obtained technological progress of the utility model is:
The utility model can adapt to the high speed rotary work of rig, avoids mud outside in the rig high speed operation to enter box house, also can stop the lubricant oil of box house to throw away simultaneously.The utility model has three roads to stop the measure that mud enters: first, the peripheral edge portion of mud umbrella has first convex edge of stretching out downwards, the corresponding casing outer side wall of mud umbrella place also has second convex edge of stretching out downwards, the sealing plate upper end is stretched between first convex edge and second convex edge, when outside mud is crossed first road sealing (sealing plate) under pump-absorb action, because the length of second convex edge will be higher than overhead gage greater than first convex edge and sealing flange, so mud is stopped, the effect of centrifugal force and gravity makes the mud can be along sealing plate with the space of second convex edge, is discharged to outside the casing automatically by several the discharge orifice that is positioned at that the casing outside distributes around overhead gage.The second, when mud too much can not in time be discharged, overhead gage and intermediate seal flange and mud umbrella had very big buffer space in the middle of the two-layer sealing between the lower convexity, can hold the mud that can not in time discharge in a large number, give the enough earial drainage time of discharge orifice.The 3rd, the hamulus that one end of the corresponding solid of rotation of sealing flange upwards stretches into oriented the 3rd convex edge inflection between the 3rd convex edge and the solid of rotation is three seals, the hamulus horizontal position be higher than sealing plate top, so when mud climbs along the outer wall of sealing flange, the hamulus part on sealing flange top can stop effectively that mud rises, and enters box house thereby make mud can't cross protruding part.
The 3rd convex edge correspondence is arranged on the Gear Root inboard, the plate part of sealing flange bottom is covered in the gear top, the lubricant oil that has got rid of in the time of can directly stopping the high-speed gear rotation, make it away from the labyrinth seal position, thereby guarantee that internal lubrication oil is not thrown out of when the high-speed gear rotary work, thereby guarantee the working life of gear and bearing, avoided the lubricant oil pollution on the environment that throws away simultaneously.In order to strengthen sealing effect, between solid of rotation and mud umbrella, the two seals circle is set simultaneously, sealing flange arranges seal ring between overhead gage.
The mud umbrella adopts the straightway cooperate with solid of rotation and inclined downward section laterally, can under the situation of rotation at a high speed, by action of centrifugal force most of mud be thrown away, thereby the mud amount around minimizing the utility model reduces mud to a certain extent and flows into seal arrangement.
