Description
Technical field
The present invention relates to a kind of thrust bearing that on the submersible pump pump housing, uses, especially submersible pump water lubrication thrust device.
Background technique
In the existing technology; The pump housing of submersible pump comprises the bearing support and the bearing at pump case, blower inlet casing, pump leaf, pump rotating shaft and two ends; Wherein blower inlet casing and pump leaf are multi-stage superimposed, rely on the axle sleeve at two ends to fix, and rely on the end washer and the bearing end play of axle sleeve to make axially locating; Because being installed as of the pump housing guarantees the pump leaf and rotates freely to make and have enough gaps between pump leaf and the blower inlet casing; Exist the pump rotating shaft to drive the pump leaf situation of going here and there up and down because generation cumulative error problem is installed in blower inlet casing and the stack of pump leaf simultaneously, the end washer of axle sleeve and bearing end produce and impact and friction in the running, and the long-term operation meeting causes wearing and tearing mutually between them; String quantity of motion progressively strengthened about the pump rotating shaft drove the pump leaf after wearing and tearing acquired a certain degree; Cause between pump leaf and the blower inlet casing from intermittence impact friction become long-time impact friction, finally produce the wearing and tearing of pump leaf and cause fault, shortened the working life of pump; The end washer and the bearing end of axle sleeve produce impact and frictionally damage in the running how to reduce submersible pump; The rotating shaft of long term maintenance pump drives the minimum string quantity of motion that the pump leaf is gone here and there up and down; Reducing the wearing and tearing of pump leaf and cause fault, prolong the working life of submersible pump, is the present technical issues that need to address.
Summary of the invention
The technical issues that need to address of the present invention provide and a kind ofly can reduce submersible pump end and the bearing housing end of axle sleeve produce and impact and frictionally damage in the running; Can the rotating shaft of long term maintenance pump drive the minimum string quantity of motion that the pump leaf is gone here and there up and down; Reduce the wearing and tearing of pump leaf and cause fault, prolong the submersible pump submersible pump water lubrication thrust device in working life.
In order to solve the problems of the technologies described above; The technological scheme of submersible pump water lubrication thrust device of the present invention is: comprise bearing housing and thrust axis tray and axle sleeve, said bearing housing is the cylindrical body that an end has the thrust flange flange, and the end face of flange of this thrust flange flange has the water chute of radially radial and circumference uniform distribution; It is whole that this water chute also extends to the inner hole wall of bearing housing; Said thrust axis tray is the flat-disk with center hole, and one end has the comb tank of radially radial and circumference uniform distribution, and it is whole that this comb tank extends to center bore inner wall; Its other end is level and smooth; Said axle sleeve is the cylindrical body that an end has the thrust flange flange, can rotate with it through endoporus and the pump rotating shaft socket that is slidingly matched, and said thrust axis tray and bearing housing are slidingly matched successively and are socketed on the axle sleeve; And the end face that makes the thrust axis tray have the comb tank touch the thrust flange flange of axle sleeve, and the end face that the thrust flange flange of bearing housing has water chute touch thrust axis tray even surface.
As optimal technical scheme of the present invention be: described bearing housing is a kind of plastic bearing cover.
Doing further to the optimal technical scheme of the invention described above, improvement is: another end face of said bearing housing also has taper self-locking flange, has the location convex tendon of symmetrical distribution simultaneously at its cylindrical outer side surface.
The optimal technical scheme of the invention described above is remake further improvement is: described thrust axis tray is a kind of plastic cement thrust axis tray, and at the hard metal gasket of its level and smooth end face bag embedding one deck.
The invention has the beneficial effects as follows: owing to replace original bearing with the present invention, wherein blower inlet casing and pump leaf multi-stage superimposed after, rely on new axle sleeve that two ends are fixed; And rely on the thrust flange flange of sleeve end and the thrust flange flange closed assembly play of thrust axis tray and bearing housing end to make axially locating, for guaranteeing that the pump leaf rotates freely to make and has enough gaps between pump leaf and the blower inlet casing, generation cumulative error problem caused axial dieback when avoiding blower inlet casing and pump leaf stack installation simultaneously when the pump housing was installed; The rotating shaft of permission pump drives the pump leaf, and string is moving up and down in predetermined range, and string quantity of motion is limited the bearing housing at two ends and the play between thrust axis tray and the axle sleeve about it, behind use the present invention; When pump turned round, axle sleeve was to rotate with it through its endoporus and the pump rotating shaft socket that is slidingly matched, and drives the thrust flange flange high speed rotating of sleeve end; Water inlet front pump leaf is not stressed; The thrust axis tray is in free state, bearing housing is produced and impacts and friction, gets into moment in the pump fast but work as water; Waterpower is up impacted the pump leaf; Up string is moving together with axle for a whole set of pump leaf, and the thrust flange flange of upper shaft bearing sleeve end is exerted pressure through the thrust axis tray by the thrust flange flange of sleeve end, it is produced impact and friction; But because the thrust axis tray that mediates can be according to pressure size self-control rotating speed; And its rotating speed must be lower than the rotating speed of axle sleeve thrust flange flange, thereby reduces the frictionally damage to the bearing housing end, simultaneously in water is full of pump after; Water can get into formation lubricating water film in the pivot friction face through the water chute of bearing housing and the comb tank of thrust axis tray; Significantly reduced the frictionally damage between them,, can also increase anti-impact force and anti-wear-resistant ability greatly if adopt plastic bearing cover and plastic cement thrust axis tray; After in water is full of pump, hydraulic pressure tends to balance gradually in the pump, and the pump leaf descends and replys the normal pump water in equilibrium position, but along with flow increases progressively, the pump leaf will be pressed down, and bear pressure with regard to the bearing that relies on the below this moment, and work and protection philosophy are the same; So having, the present invention can reduce submersible pump end and the generation impact of bearing housing end and the frictionally damage of axle sleeve in the running; Can the rotating shaft of long term maintenance pump drive the minimum string quantity of motion that the pump leaf is gone here and there up and down; Reduce the wearing and tearing of pump leaf and cause fault; Strengthen the fixing with one heart of pump rotating shaft upper end simultaneously, effectively prolonged the submersible pump beneficial effect in working life.
