Abstract
The utility model is a vertical bottom suction centrifugal pump, which comprises a pump body and a motor; an intermediate bracket is arranged between the pump body and the motor; the utility model characterized in that the bottom of the pump body is provide with a water inlet; and the inlet directs downwards; one end of the pump body is provided with a water outlet; the outlet is vertical to the shaft axis of the pump. The utility model has the advantages that 1. Vertical bottom suction structure is adopted; the suction mouth is downward vertically; the center of gravity moves downwards after the suction tube is installed to improve the stability of equipment operation. 2. The utility model is suitable for sucking and discharging low-level medium with high working efficiency, has lower cavitation excess amount, and can greatly improve suction vacuum degree. 3. The equipment occupation can be reduced as compared with the horizontal pump 4. The utility model can reduce the vertical distance between the centerline of pump impeller and liquid surface of the medium delivered; and can substantially expand the application range of the centrifugal pump under the working condition of suction and discharge of low-level medium. 5. The utility model overcomes the defects of longer shaft, higher torque, heavier wear, easily corroded and easily broken of the long shaft submerged pump as compared with the long shaft.
Description
Technical field
The utility model patent relates to a kind of pump, particularly relates to a kind of pump shaft axis perpendicular to the pump foundation plane, and the impeller center is arranged on the vertical type perpendicular bottom inhalation centrifugal pump that the above suction port of liquid level is arranged on pump shaft axis lower end.Hereinafter to be referred as vertical bottom inhalation centrifugal pump.
Background technique
To be a kind of pump shaft axis be arranged on the centrifugal water pump of pump vertical direction perpendicular to the base plane drive motor to vertical centrifugal pump, and the vertical centrifugal pump of extensive use at home and abroad at present has following several:
1, riser centrifugal pump
The intake-outlet of riser centrifugal pump is widely used in the pipe-line system supercharging water feeding perpendicular to the pump shaft axis.
2, vertical multi-stage centrifugal pump
The intake-outlet of vertical multi-stage centrifugal pump is widely used in the high building domestic water perpendicular to the pump shaft axis, operating modes such as feedwater supercharging, fire-fighting.
3, liquid following formula centrifugal pump
The water intake of liquid following formula centrifugal pump is positioned at pump shaft axis lower end, and water outlet is arranged on below the liquid level with the impeller center that raises up after shaft axis is vertical, is widely used in promoting the operating mode of low liquid level medium.Because all very long distortion that when driving torque is bigger, is distorted easily of its pump shaft, vibration.According to the length change needs a plurality of guide bearings are set, so its consumed power is bigger, axle is bigger with guide bearing wearing and tearing, especially under burn into abrasion operating mode through regular meeting's off-axis, keep in repair very inconvenient.
Summary of the invention
It is a kind of that the purpose of this utility model is to provide, and sucts performance height, stable, and easy for installation, floor space is little, the vertical type perpendicular bottom inhalation centrifugal pump of easy access maintenance.
The technological scheme that adopts is:
Vertical type perpendicular bottom inhalation centrifugal pump comprises the pump housing and motor, is provided with intermediate support between the pump housing and the motor, its structure outline is that the bottom of the described pump housing is provided with water intake, and water intake down, and a side of the described pump housing is provided with water outlet, and water outlet is perpendicular to the pump shaft axis.
The bottom of the above-mentioned pump housing has supporting foot, and supporting foot is fixed on one and is connected with on the flange plate of suction pipe, and the edge of flange plate is fixed on the pump foundation plane.
Corresponding both sides are fixed with supporting foot on the above-mentioned pump housing, and supporting foot is fixed on the pump foundation plane.
Add electric machine support and bearing support between above-mentioned motor and intermediate support, between electric machine support and the bearing support supporting foot is installed, and supporting foot is dull and stereotyped, be fixed on the pump foundation plane.
The water outlet of the above-mentioned pump housing is connected with mouth of pipe elbow up.
Major advantage of the present utility model is:
1, adopt suction structure of the vertical end, suction port is installed the suction pipe tailheaviness and is moved down vertically downward, has increased stable equipment operation.
2, be applicable to suction low level medium, high working efficiency, net positive suction head is low, and degree of suction vacu um increases substantially.
3, compare with horizontal pump, can reduce occupation area of equipment.
4, pump impeller center line and be transferred perpendicular distance between the medium liquid level can be reduced, and the using scope of centrifugal pump under suction low level medium operating mode can be expanded significantly.
5, guaranteeing that according to the highest liquid level face of medium and pump foundation plane distance rigidity pump shaft operation stability and impeller center line are positioned under the prerequisite more than the liquid level, increased substantially the ability that sucts of pump, be particularly useful for the higher medium of suction vapor pressure, compare with long shaft submerged pump, overcome that long shaft submerged pump axial length, moment of torsion are big, abrasion are big, perishable, the defective of easy off-axis.
