Abstract
The flexible mixed granular filler is used to seal water flowing axially out of the water pump chamber. Inside the sealed filler chamber, inner flexible square filler, flexible mixed granular filler, outer flexible square filler, pump gland, gland fastening screw and nut are connected successively. After the water pump runs, the nut is regulated gradually to make the filler coat the surface of the pump shaft closely to seal water inside the flexible filler.
Description
Affiliated technical field
The present invention relates to a kind of sealing technique of pump seal, especially be suitable for the sealing of the relatively poor and soda acid pump shaft of water quality.
Background technique
The stuffing box packing that at present general water pump uses mainly is as shaft packing with butter packing, graphite packing, metal packing etc.Behind starting of pump station, filler plays seal action between pump chamber and closed chamber, makes the interior water of pump not along axial outflow.But along with the rotation of pump shaft, pump shaft constantly weares and teares to filler, gradually big to the gap that makes stuffing box packing and pump shaft, again because the mechanical admixture in the water overflows, aggravated the wearing and tearing of stuffing box packing and pump shaft simultaneously, under abominable water quality, it is more outstanding that the situation that stuffing box packing and pump shaft are worn seems.As the slurry pump that use in the mine, slag flushing pump, acid and alkali pumps that the power station uses all can quicken the wearing and tearing of pump shaft because of the wearing and tearing of filler.After pump shaft and the stuffing box packing wearing and tearing, the water that spills can enter in the bearing chamber of pump, cause the damage of emulsification of lubricant and bearing, and the leakage of acid and alkali pumps can directly cause the pollution to the face of land and surrounding environment.We can say and since the existence of filler just in use at present problem, not only shortened working life of pump, increased the maintenance number of times, also increased cost of production simultaneously.
Summary of the invention
In order to overcome the ubiquitous filler wearing and tearing of present pump shaft packing material, to leak and the pump shaft wear problems, the invention provides a kind of flexible mixed particle filler, this flexible mixed particle can not only seal up the water that flows out vertically from pump chamber effectively, and can adapt to the abominable water quality and the working medium of strong acid and strong base, after adding the granular filler grain of this flexible hybrid, pump shaft can accomplish that the granular filler of pump shaft and flexible hybrid does not does not wear and tear substantially under turning round for a long time.
The technical solution used in the present invention is: stuffing box packing indoor be provided with two ends adopt in outside flexible square body filler, adopt the granular filler of flexible hybrid in the middle of the flexible square body filler in the interior outside, be followed successively by the flexible square body filler of inboard flexible square body filler, the granular filler of flexible hybrid, the outside in the filler chamber and press, tightly apply in pump shaft surface and filler chamber by the pump housing pressing flange disk tightening nut on the pump housing pressing flange disk.Making its filler be full of filler chamber also tightly applies on the pump shaft surface.Because the granular filler of flexible hybrid spheroid in the running of pump shaft does relative motion on the pump shaft surface, and several motion water holding rings of forming by spheroid of corresponding generation, behind starting of pump station, to live from the water seal that pump chamber flows out vertically, through under the tight power of adjusting pump housing pressing flange disk tightening nut, reach the watertight purpose in filler place again.
The invention has the beneficial effects as follows: seal above-mentioned filler through disposable filling, after the tight power through adjusting pump housing pressing flange disk tightening nut, above-mentioned filler place can accomplish water-tight, not overheated behind the pump startup; Because what flexible square body filler in the interior outside and mixing particulate filler adopted is the selflubricating material, so the frictional force between this filler and the pump shaft is minimum, pump shaft does not does not wear and tear substantially.The above-mentioned filler in pump housing maintenance back is reusable, and installation, easy to maintenance, can prolong the working life of pump shaft, reduces production costs.

Embodiment
As shown in Figure 1, a kind of flexible mixed particle filler, in the pump housing hydroecium 1 and the filler chamber 3 between the pump shaft 2 in the pump housing 10, it is in the stuffing box packing chamber, inboard flexible square body filler 4, the granular filler 5 of flexible hybrid, the flexible square body filler 6 in the outside, pump housing pressing flange disk 7, pump housing pressing flange disk clamping bolt 8, pump housing pressing flange disk tightening nut 9 are linked in sequence.Stuffing box packing indoor be provided with two ends adopt in outside flexible square body filler, adopt the granular filler of flexible hybrid in the middle of the flexible square body filler in the interior outside, be followed successively by the flexible square body filler of inboard flexible square body filler, the granular filler of flexible hybrid, the outside in the filler chamber and press, tightly apply in pump shaft surface and filler chamber by the pump housing pressing flange disk tightening nut on the pump housing pressing flange disk.
Described inside and outside flexible square body filler and the granular filler of flexible hybrid coexist in the filler chamber.The granular diameter of the granular filler of described flexible hybrid is 3-5mm.
Usually the loading that mixes particulate filler is after compressing above-mentioned filler with pump housing pressing flange disk, and pump housing pressing flange disk end face and filler chamber's exterior edge face 5-8 millimeter are advisable, and is convenient to the adjustment of the tight power of above-mentioned filler behind the pump operation.What interior flexible square body filler in the outside and mixing particulate filler adopted is the selflubricating material, i.e. waterproof antiwear selflubricating material is prior art, so be not repeated.
Finish fill the flexible square body filler in inboard flexible square body filler, the granular filler of flexible hybrid and the outside after, by the tight power of pump housing pressing flange disk tightening nut, with the interior outside and the granular filling compaction of flexible hybrid, be full of filler chamber and tightly apply on the pump shaft surface.After pump is opened and run well, adjust the tight power of pump housing pressing flange disk tightening nut again, the compaction forces of this above-mentioned filler and pump shaft is suitable, reaches water-tight, not overheated purpose.
In Fig. 2, the granular filler of flexible hybrid is positioned in the middle of the flexible square body filler in the outside.Globule in the granular filler of flexible hybrid is distributed in the pump shaft surface.When water pump under static state, globule is a contact on the pump shaft surface; Behind pump operation, a plurality of points on pump housing surface form many lines, utilize linear velocity to increase resistance and leak effect.The speed that is higher than current simultaneously because of spherular axial velocity can be decomposed along the current that pump shaft flows out, and changes its flow direction and flow velocity, and current are sealed between inboard flexible square body filler and the granular filler of flexible hybrid.
