Abstract
The utility model provides a vertical centrifugal pump, and belongs to the technical field of water pumps. The vertical centrifugal pump resolves the problems that an existing split-type centrifugal pump is large in noise, short in service life and small in application range. The vertical centrifugal pump comprises a motor and a pump body located under the motor and formed by an upper end cover and a lower end cover, wherein a pump cavity is formed inside the pump body, the lower end cover is provided with a water inlet and a water outlet which are communicated with the pump cavity, a rotation shaft of the motor penetrates through the upper end cover and extends into the pump cavity and is sleeved with an impeller located inside the pump cavity, a water fender is arranged between the motor and the upper end cover, a sealing bearing is arranged between the upper end cover and the rotation shaft, and a mechanical seal is arranged between the upper end cover and the rotation shaft. The vertical centrifugal pump has the advantages of being long in service life, wide in application range and the like.
Description
Technical field
The utility model belongs to pump technology field, relates to a kind of vertical centrifugal pump.
Background technique
Existing vertical centrifugal pump impeller water intake is downward, and during work, medium is low in and high out by impeller, and the medium of being pumped produces a downward active force to impeller.The weight of the moving elements such as impeller, pump shaft, motor rotor produces gravity downwards.These two power stack up and act on bearing, and bearing axial load is strengthened, thereby have shortened the working life of bearing, and the increase of resistance also can make noise strengthen, consume electric power.In addition, existing centrifugal pump generally adopts split-type structural, and split type centrifugal pump shaft is to large with circular runout, and working life is low.Existing centrifugal pump can only be carried a kind of liquid, and Applicable scope is little.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed a kind of vertical centrifugal pump applied widely.
The purpose of this utility model can realize by following technical proposal:
This vertical centrifugal pump, comprise motor, be positioned at the pump housing being formed by upper end cap and lower end cap of motor below, in the described pump housing, there is pump chamber, on described lower end cap, there is the water intake and the water outlet that are connected with pump chamber, it is characterized in that, the rotating shaft of described motor is passed upper end cap and is stretched in pump chamber, in described rotating shaft, be arranged with the impeller that is positioned at pump chamber, between described motor and upper end cap, be provided with manger board, between described upper end cap and rotating shaft, there is sealing bearing, and there is mechanical seal between described upper end cap and rotating shaft.
In this vertical centrifugal pump, impeller is directly fixedly installed in the rotating shaft of motor, overcome split type centrifugal pump shaft to the shortcoming large with circular runout, reduced the infringement of axial runout to motor, the radial and axial load that active balance centrifugal pump produces in the running, thus guaranteed centrifugal pump operate steadily, vibrate little, noise is low.Rubber corrugated tubular construction is generally selected in mechanical seal, the both ends of the surface that the linear sealing that sealing in traditional mechanical seal is enclosed by O shape changes rubber parts into seal, material is ternary one third rubber, when water medium, improved sealing effect, seal face adopts Hardmetal materials, effectively improves the working life of sealing.
In above-mentioned vertical centrifugal pump, described water intake and water outlet are positioned on same center line, and described water intake is provided with outlet valve one, and described water outlet is provided with outlet valve two.
The bore of water intake and water outlet is identical, and is positioned on same center line, can as valve, be installed among pipeline, and compact appearance is attractive in appearance, and floor space is little.During work, the clockwise high speed operation of impeller, produce higher energy by water intake to water outlet output liquid, while there is vibration, open outlet valve, reduce pump chamber internal cause net positive suction head and produce the impact of gas on pump, meet the conveying of various liquid mediums in pipeline.
Compared with prior art, this vertical centrifugal pump has the following advantages:
The bore of water intake and water outlet is identical, and is positioned on same center line, can as valve, be installed among pipeline, and compact appearance is attractive in appearance, and floor space is little.Impeller is directly fixedly installed in the rotating shaft of motor, overcome split type centrifugal pump shaft to the shortcoming large with circular runout, reduced the infringement of axial runout to motor, the radial and axial load that active balance centrifugal pump produces in the running, thus guaranteed centrifugal pump operate steadily, vibrate little, noise is low.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of preferred embodiment of providing of the utility model.
In figure, 1, motor; 21, upper end cap; 22, lower end cap; 31, water intake; 32, water outlet; 4, impeller; 5, manger board; 6, sealing bearing; 7, mechanical seal; 81, outlet valve one; 82, outlet valve two.
Embodiment
Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
Vertical centrifugal pump as shown in Figure 1, comprises motor 1, is positioned at the pump housing consisting of upper end cap 21 and lower end cap 22 of motor 1 below, has pump chamber in the pump housing, has the water intake 31 and the water outlet 32 that are connected with pump chamber on lower end cap 22.As shown in Figure 1, the rotating shaft of motor 1 is passed upper end cap 21 and is stretched in pump chamber, is arranged with the impeller 4 that is positioned at pump chamber in rotating shaft, between motor 1 and upper end cap 21, is provided with manger board 5, between upper end cap 21 and rotating shaft, there is sealing bearing 6, and between upper end cap 21 and rotating shaft, there is mechanical seal 7.
In this vertical centrifugal pump, impeller 4 is directly fixedly installed in the rotating shaft of motor 1, overcome split type centrifugal pump shaft to the shortcoming large with circular runout, reduced the infringement of axial runout to motor 1, the radial and axial load that active balance centrifugal pump produces in the running, thus guaranteed centrifugal pump operate steadily, vibrate little, noise is low.Rubber corrugated tubular construction is generally selected in mechanical seal 7, the both ends of the surface that the linear sealing that sealing in traditional mechanical seal 7 is enclosed by O shape changes rubber parts into seal, material is ternary one third rubber, when water medium, improved sealing effect, seal face adopts Hardmetal materials, effectively improves the working life of sealing.
Concrete, as shown in Figure 1, water intake 31 and water outlet 32 are positioned on same center line, and water intake 31 is provided with outlet valve 1, and described water outlet 32 is provided with outlet valve 2 82.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
