Abstract
The invention provides an improved pump shaft sleeve structure for a horizontal split double-entry pump, which can be used for effectively reducing the abrasion of mud in water to a pump body and reducing equipment maintenance and care cost. A pump shaft penetrates through the pump body, and a shaft sleeve is sheathed outside the pump shaft. The improved pump shaft sleeve structure is characterized in that a wear ring is installed between the shaft sleeve and the pump body, and the wear ring is fixed on the pump body through a pin.
Description
Technical field
The present invention relates to open double suction pump constructing technology field in horizontal, be specially the improved horizontal pump shaft axle sleeve structure of driving double suction pump that is used for.
Background technique
At present general drive double suction pump in horizontal, pump shaft 1 passes the pump housing 3, axle sleeve 2 directly is set on the pump shaft 1, see Fig. 1, its shortcoming is that the pump housing 3 is non-rotary body, when containing a large amount of silt in the water, easily causes wearing and tearing to the pump housing 3, it is long to change pump housing cost height, replacement cycle, its equipment maintenance cost height.
Technological scheme
At the problems referred to above, the invention provides the improved horizontal pump shaft axle sleeve structure of driving double suction pump that is used for, it can effectively reduce, and silt reduces the equipment maintenance cost to the wearing and tearing of the pump housing in the water.
Its technological scheme is such, and pump shaft passes the pump housing, and the pump shaft outer cover is equipped with axle sleeve, it is characterized in that: between the described axle sleeve and the pump housing wear ring is installed, described wear ring is fixed on the described pump housing by pin.
It is further characterized in that: the maximum deflection the when gap between described wear ring and the axle sleeve is moved greater than described pump shaft; Gap delta 〉=0.03mm between described wear-resistant sleeve and the axle sleeve.
Compare with pump shaft axle sleeve structure in the past, the beneficial effect of structure of the present invention is: install wear ring additional between the axle sleeve and the pump housing, and wear ring is fixed on the pump housing by pin, thereby directly contact with current by wear ring, the wearing and tearing that wear ring causes when bearing water impact with axle sleeve as easily damaged parts have effectively reduced the wearing and tearing to the pump housing, and wear ring and axle sleeve wearing and tearing back maintenance, change convenient, have greatly and shorten the replacement cycle, reduce the equipment maintenance cost.
Description of drawings
Fig. 1 has pump shaft axle sleeve structure schematic representation now;
Fig. 2 is a pump shaft axle sleeve structure schematic representation of the present invention.
Embodiment
See Fig. 2, structure of the present invention, its pump shaft 1 passes the pump housing 3, and pump shaft 1 outer cover is equipped with axle sleeve 2, between the axle sleeve 2 and the pump housing 3 wear ring 4 is installed, and wear ring 4 is fixed on the pump housing 3 by pin 5.Maximum deflection when the gap delta between wear ring 4 and the axle sleeve 2 is moved greater than pump shaft 1; Gap delta 〉=0.03mm between wear ring 4 and the axle sleeve 2.
Claims (3)
1. improvedly be used for the horizontal pump shaft axle sleeve structure of driving double suction pump, pump shaft passes the pump housing, and the pump shaft outer cover is equipped with axle sleeve, it is characterized in that: between the described axle sleeve and the pump housing wear ring is installed, described wear ring is fixed on the described pump housing by pin.
2. the improved horizontal pump shaft axle sleeve structure of driving double suction pump that is used for according to claim 1 is characterized in that: the maximum deflection the when gap between described wear ring and the axle sleeve is moved greater than described pump shaft.
3. the improved horizontal pump shaft axle sleeve structure of driving double suction pump that is used for according to claim 2 is characterized in that: the gap delta 〉=0.03mm between described wear-resistant sleeve and the axle sleeve.
