Description
Technical field
The utility model relates to mixed flow pump, the sealing configuration particularly in mixed flow pump between impeller and pump cover.
Background technique
Mixed flow pump is a kind of pump between centrifugal pump and axial-flow pump.Under prior art, between the impeller of mixed flow pump and pump cover, usually adopt plane sealing.Certain gap must be needed between the impeller rotated and fixed pump lid.Due to the error in manufacture process, in various degree there is axial motion and circular runout, usually adopt paper washer adjusting play.The size in this gap directly affects the efficiency of pump, has influence on the suction lift of sealing effect and pump.If this gap is too large, the sealing effect between impeller and pump cover is just poor, the suction lift also corresponding reduction of pump.In addition, this gap, after long term mechanical wearing and tearing, constantly can increase, also can cause the efficiency of pump and the decline of suction lift.
Summary of the invention
Problem to be solved in the utility model: the plane sealing poor effect between impeller and pump cover, affects working efficiency and the suction lift of pump, also easily occurs that mechanical wear causes pump performance and water absorbing properties to decline simultaneously.
For solving the problem, the scheme that the utility model adopts is as follows:
A mixed flow pump for water-ring seal, comprises the pump housing, impeller, pump cover, bonnet, bearing support, pump shaft.The pump housing is the shell construction of inner hollow; Pump cover and bonnet are arranged on the pump housing respectively, for sealing the pump housing; Pump cover inner hollow, for connecting intake pipe; Bearing support is arranged on bonnet; Pump shaft is arranged on bearing support by the bearing in bearing support, and penetrates the inside of the pump housing through bonnet intermediate throughholes; Be provided with for airtight and watertight padding part between bonnet and pump shaft; Impeller is arranged on the end of pump shaft, and is positioned at the pump housing; Impeller comprises wheel shaft, blade and wheel rim; Blades installation is on wheel shaft; Wheel shaft, blade and wheel rim form a wheel hub structure; Gap between blade and blade forms water channel; Seal face is formed between wheel rim and pump cover; It is characterized in that, wheel rim and that seal face between pump cover is provided with tooth is convex; Tooth is convex have multiple, along wheel rim circumferentially alternately; Pump cover and seal face between wheel rim is provided with the convex teeth groove matched with tooth.
Further, all there is certain distance in the convex outer with wheel rim of tooth and interior edge, or tooth is convex in edge in wheel rim, and all there is certain distance with the outer of wheel rim.
Further, along in the circumference of wheel rim, tooth is convex is provided with transitional surface with wheel rim; Transitional surface is inclined-plane or cambered surface, or along in the circumference of wheel rim, be section between the convex and wheel rim of tooth, and the normal direction of this section and wheel rim has angle, this angle is 0 ~ 20 degree.
Further, the number that on wheel rim, tooth is convex is 8 ~ 32.
Further, the height that on wheel rim, tooth is convex is 2 ~ 6mm.
Technique effect of the present utility model is as follows:
1, during mixed flow pump work of the present utility model, the water High Rotation Speed moved in teeth groove by the tooth raised strips of rotating is formed water ring and realizes suction chamber and pumping chamber sealing.
2, improve the unlatching efficiency of pump.When mixed flow pump is in off position, usually have ponding to exist in the pump housing, after now opening mixed flow pump, the tooth of High Rotation Speed is convex can be taken up ponding, makes ponding in teeth groove, rotate the water ring forming rapidly sealing.And under prior art, usual air-water separation efficiency comparison is poor, opens and will spend the long time.
3, the requirement of the machining accuracy of sealing configuration between impeller and pump cover is reduced.The utility model realizes sealing by the water ring rotated, therefore not high to the required distance between impeller and pump cover, easily processes, and owing to wanting much bigger making not wear and tear each other under the gap ratio prior art between impeller and pump cover.
4, under the utility model structure, the water High Rotation Speed formation water ring moved in teeth groove by the tooth raised strips of rotating realizes suction chamber and pumping chamber sealing has good sealing effect, improves suction lift, namely improves the suction journey of pump.
