Description
Technical field
The present invention relates to pump housing technical field, more particularly to a kind of half-opened impeller stainless steel centrifugal pump.
Background technology
Centrifugal pump is classified from different perspectives different names, and one of which classification can be divided into centrifugal pump with shrouded impeller, open type
Impeller centrifugal pump and centrifugal pump with semien closed impellerpump, half-opened impeller only have back shroud, and it is easy to precipitate or containing solid suitable for conveying
The liquid of body suspension, its efficiency is between open type and centrifugal pump with shrouded impeller.
Centrifugal pump is widely used as a kind of medium conveying apparatus.Traditional centrifugal pump mainly by the pump housing, turn
Axle, impeller and gland seal device composition, the pump housing are provided with medium inlet port, outlet of the medium and connection medium inlet port and medium flow field
The runner of outlet.Generally, impeller uses double shrouded wheel more, and requirement of the double shrouded wheel to runner is higher, and the flow in the pump housing needs
Wider structure is designed as, and such design can only be for using, for low discharge field then during the larger operating mode of pumped (conveying) medium
The conveying to medium can not be implemented.When having the medium of particle for conveying, the particle in medium, which easily glues, to be blocked up in double shrouded wheel,
Centrifugal force is had influence on, also has influence on the performance of the pumped (conveying) medium of centrifugal pump；Meanwhile the particle in medium can cause to pump body
Impingment corrosion, make the pump housing and its too fast abrasion of inner body, shorten the service life of the pump housing.
For not high, the service life that solves transfer efficiency present in half-opened impeller stainless steel centrifugal pump in the prior art
It is short, and the technological deficiency of quick abrasion, a kind of half-opened impeller stainless steel centrifugal pump of present invention proposition.
The content of the invention
The defects of present invention aims at solution current prior art and design principle both at home and abroad in the field and deficiency,
Design a kind of half-opened impeller stainless steel centrifugal pump.
The present invention is realized by following technical scheme, a kind of half-opened impeller stainless steel centrifugal pump, including pump case component,
Impeller, bearing, pump cover and motor, the impeller are socketed on the bearing by axle sleeve, and the impeller side passes through spring pad
Circle is contacted with sliding interstage sleeve one, and opposite side is contacted by mechanical seal contact slide interstage sleeve two, and described mechanical seal can pass through
Described slip interstage sleeve two is fastened in the cylindrical shape neck in described pump cover, and described slip interstage sleeve one passes through interstage sleeve nut
Gap between one adjustment and the impeller, slip interstage sleeve two adjust the gap between the impeller by interstage sleeve nut two,
Described impeller is half-opened impeller.
Further, described centrifugal pump also includes dust cap, middle O-ring, hexagon socket head cap screw, small O-ring, plug screw, big O
Type circle, hex nut, rubber washer；Described dust cap is connected by hexagon socket head cap screw with the pump case component, described pump
Middle O-ring is provided between shell component and the dust cap, the pump case component has entrance, and the shell of the pump case component leads to
Cross plug screw and small O-ring is fixed, the entrance connects suction casing, and the suction casing is by big further, O-ring and institute
Pump cover sealed connection is stated, forms centrifugal pump inner chamber, the impeller is in described inner chamber.
Further, the impeller is socketed with the bearing by axle sleeve, and by hex nut and rubber washer with
The bearing seal.
Further, it is slidingly sealed between the mechanical seal and slip interstage sleeve two.
Further, a diameter of 150mm of the centrifugal pump inlet, rated head 78m, carry out impeller outer diameter and cut first
Mode.
Further, a diameter of 100mm of the centrifugal pump inlet, rated head 60m, carry out impeller outer diameter and cut first
Mode.
Further, the working environment of centrifugal pump of the invention is：Pumped (conveying) medium temperature is no more than 260 DEG C, pumped (conveying) medium
Ph value 4-10, be not more than 3.2mm containing Solids Particle Diameter in pumped (conveying) medium, volume is no more than 10%.
It is preferred that the centrifugal pump is single-suction single-stage centrifugal pump, liquid flows into from the side of impeller.
The centrifugal pump of the present invention is because impeller is contacted by spring washer with sliding interstage sleeve one, because spring washer is with one
Fixed elasticity, realizes impeller Elastic Contact, is advantageously implemented impeller with sliding the motor-driven adjustment of interstage sleeve one, special with reference to following collaboration
Sign, i.e., opposite side is contacted by mechanical seal contact slide interstage sleeve two, and described mechanical seal can pass through described slip interstage sleeve
Two are fastened in the cylindrical shape neck in described pump cover, and described slip interstage sleeve one passes through the adjustment of interstage sleeve nut one and the leaf
Gap between wheel, the gap are also as aforementioned gap is identical, and size is adjustable, and width runner is controllable optional, has widened pump
Performance range, compared with double shrouded wheel self-balanced multiple-stage centrifugal pump, the present invention had both been avoided that the too fast concentration abrasion of the part of pump,
And after appearance is worn, can compensate within certain limits, thus make the operating lifetime of parts, the hydraulic performance of pump
It is maintained.
In invention, the impeller also can be replaced unshrouded impeller, to tackle people's demand different to pump.And the present invention
Pump it is removable interchangeable, it is convenient, flexible, use occasion increase.
The semi-open type centrifugal pump of the present invention can be high with power, and lift is big, and remote realize send bigcatkin willow water.Inventor is by examination
Existing impeller sets cooperation is issued after examination and approval, the above-mentioned angle of the specific present invention and inclination angle are set, using water guide blade and divide waterleaf
Specific angle synergy between piece, realizes that water absorbing force is maximum because vacuum caused by rotation is maximum, realizes conveying power
Greatly, design science.It is of the invention simple to operate herein, it is easy to operate, there is larger practicality, it is suitable to promote.
In invention, centrifugal pump with middle O-ring, hexagon socket head cap screw, small O-ring, plug screw, big O-ring, hex nut,
Rubber washer；Their good sealing effects between impeller, ensure that gap deposits change effect, it is therefore prevented that solid particle accumulates in
Gap location causes concentration of local to be worn, and seal and impeller will not be made premature breakdown occur, can only be changed after will not producing damage
Loss.
