Abstract
The utility model relates to a mechanical sealing device which is particularly suitable for a desulfurizing pump device. The mechanical sealing device comprises a shaft housing, a gland bush, a rotor ring and a seal stationary ring, wherein the rotor ring is fixed in a ring groove of the shaft housing, the shaft housing is fixed with a drive bolt; the seal stationary ring is fixed at the center of the end face of the gland bush, and the tail part of the seal stationary ring is provided with a thrust ring. The back face of the thrust ring is provided with a plurality of spring propping thrust rings, and springs are arranged in spring holes arranged at the bottom part of the gland bush. The gland bush is provided with a rinsing water inlet and a liquid discharge opening. The inner part of the gland bush is provided with an annular channel which is communicated with the rinsing water inlet, and the inner wall of the annular channel is provided with splattering holes which are communicated with the bottom parts of the spring holes one by one. The mechanical sealing device can rinse a plurality of points of the springs, thereby thoroughly solving the problem of mechanical seal failure caused by the elasticity loss because of spring blocking.
Description
(1) technical field:
The utility model relates to a kind of mechanical seal device, is specially adapted to use on the desulfur pump device.
(2) background technique:
In the various pumps of fed sheet of a media,, then exist certain clearance between them because the pump housing and pump shaft have relative movement.In order to stop fed sheet of a media to let out from the gap, various pumps all are provided with seal arrangement.At present the medium carried of desulfur pump has easy crystallization, characteristics that viscosity is big, seal arrangement adopts spring and the isolated mechanical seal structure of medium more, this seal arrangement in use for some time, the medium of leakage can make spring stop up, spring follows the string and makes seal failure.At this situation, the sealing device has the structure of washing spring, but the backwashing manner that this device uses is the single-point flushing, promptly have only one current that all springs are washed, caused the dead angle that much can't be flushed to like this, spring has still been faced stop up danger, made spring failure, cause seal face to be opened, thereby cause mechanical seal to be lost efficacy.
(3) summary of the invention
The utility model is exactly at the defective of prior art and deficiency, for desulfur pump provides a kind of seal arrangement that spring is carried out the multiple spot flushing, thoroughly solves because of spring stops up to follow the string, thus the problem that causes mechanical seal to be lost efficacy.Its technological scheme is as follows:
It comprises axle sleeve, gland, rotating ring and stationary ring.Rotating ring is fixed in the circular groove of axle sleeve, fixed conveyor screw on the axle sleeve; Stationary ring is fixed in the end face center of gland, is provided with throw-out collar at the afterbody of stationary ring, and throw-out collar is equipped with stop pin, and an end of stop pin embeds in the anti-rotation groove of stationary ring afterbody, and the other end embeds in the anti-rotation hole of gland.Be provided with a plurality of springs at the throw-out collar back side and push against throw-out collar, spring places in the spring eye that gland bottom offers, and positioning block and gland restrictor ring are equipped with in the gland back side.On gland, have sparge water import and liquid port.Its key technology is to be provided with ring runner to communicate with the sparge water import in gland inside, offers tap hole and corresponding one by one the communicating in spring eye bottom at the inwall of ring runner.
Compared with prior art the beneficial effects of the utility model are: the sparge water that enters gland inner annular runner, the shunting action of the tap hole that communicates through several spring eye bottoms, be divided into some strands of current each spring is carried out man-to-man special flushing, can effectively prevent the slurry medium spring blocking hole that desulfur pump is carried like this and cause the problem that mechanical seal was lost efficacy.Lose bullet thereby thoroughly solved spring because the slurries deposition is stopped up, and cause the dynamic and static ring face opening, cause the problem that mechanical seal was lost efficacy, greatly the working life of prolonged mechanical seal arrangement.
(4) description of drawings
Fig. 1 is the utility model structural representation.
(5) embodiment
Referring to accompanying drawing, the utility model comprises axle sleeve 11, gland 15, rotating ring 3 and stationary ring 4, and rotating ring 3 is fixed in the circular groove of axle sleeve 11, and fixed conveyor screw 2 on the axle sleeve 11 is sealed by rotating ring O shape circle 17 between rotating ring 3 and the axle sleeve 11.Stationary ring 4 is fixed in the end face center of gland 15, gland 15 is sealed by stationary ring O shape circle 5 with stationary ring 4, afterbody at stationary ring 4 is provided with throw-out collar 6, throw-out collar 6 is equipped with stop pin 13, one end of stop pin 13 embeds in the anti-rotation groove of stationary ring 4 afterbodys, the other end embeds in the anti-rotation hole of gland 15, in case the stop stationary ring rotates stationary ring relative to friction.End face center fixation at gland 15 is formed the stationary ring system by stationary ring restrictor ring 14 and stationary ring 4, throw-out collar 6.Be provided with a plurality of springs 7 at the back side of throw-out collar 6 and push against throw-out collar, thereby the end face of stationary ring 4 and the end face of rotating ring 3 are fitted tightly, spring 7 is positioned in the spring eye of offering gland 15 bottoms.Positioning block 9 and gland restrictor ring 20 are equipped with in gland 15 back sides, and positioning block 9 one ends insert in the groove of axle sleeve 11 cylindricals, and by screw that itself and gland 15 is fixing.Gland 15 links by the bolt hole 19 and the pump housing, seals with gland O shape circle 16 between the gland 15 and the pump housing.Axle sleeve 11 fixes by transmission ring 10 and pump shaft 18, is sealed by axle sleeve O shape circle 1 between axle sleeve 11 and the pump shaft 18.On gland, have sparge water import 22 and liquid port 12.Pull down positioning block 9 during running, during the desulfur pump running, pump shaft 18 drives transmission ring 10 by the Cock screw 21 that is fixed on the pump shaft, transmission ring 10 drives axle sleeve 11, axle sleeve 11 drives rotating ring 3 by transmission screw 2 and rotates, and makes stationary ring 4 and rotating ring 3 relative runnings, thereby reaches sealing effect.Its key technology is to be provided with ring runner 8 to communicate with sparge water import 22 in gland inside, offers a plurality of tap holes 23 and corresponding one by one the communicating in spring eye bottom at the inwall of ring runner 8.Sparge water enters ring runner 8 from sparge water import 22, is divided into several strands of current through the tap hole 23 bottom the spring eye, and per share current wash one to one specially to each spring.So just form multi-strand flow to the mode that a plurality of springs carry out the multiple spot flushing, can prevent effectively that the slurries that leak are deposited on spring blocking in the spring eye and make spring lose bullet, caused the dynamic and static ring face opening, thoroughly solved the problem that mechanical seal was lost efficacy.Sewage after the flushing is discharged outside the mechanical seal device through liquid port 12.
