Abstract
The utility model provides an improved pump shaft sleeve structure used for a horizontal middle-open double-suction pump, which can effectively reduce the wear to the pump body by the silt in water, and reduce the maintenance cost of the equipment. A pump shaft penetrates a pump body, and a shaft sleeve is sleeved outside the pump shaft; and the improved pump shaft sleeve structure is characterized in that a wearing ring is installed between the shaft sleeve and the pump body and fixed on the pump body through a pin.
Description
Technical field
The utility model relates to opens double suction pump constructing technology field in horizontal, is specially a kind of 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, and 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, is prone to the pump housing 3 is caused wearing and tearing; Replacing pump housing cost is high, the replacement cycle is long, and its equipment maintenance cost is high.
The model utility content
To the problems referred to above, the utility model provides a kind of improved horizontal pump shaft axle sleeve structure of driving double suction pump that is used for, and 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 said axle sleeve and the pump housing wear ring is installed, said wear ring is fixed on the said pump housing through pin.
It is further characterized in that: the maximum deflection the when gap between said wear ring and the axle sleeve is moved greater than said 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 the utility model structure is: between the axle sleeve and the pump housing, install wear ring additional, and wear ring is fixed on the pump housing through 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 is existing pump shaft axle sleeve structure schematic representation;
Fig. 2 is the pump shaft axle sleeve structure schematic representation of the utility model.
Embodiment
See Fig. 2, the utility model structure, 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 through 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. one kind improvedly is used for the horizontal pump shaft axle sleeve structure of driving double suction pump, 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 said axle sleeve and the pump housing wear ring is installed, said wear ring is fixed on the said pump housing through pin.
2. a kind of 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 said wear ring and the axle sleeve is moved greater than said pump shaft.
3. a kind of 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.
