Abstract
The utility model relates to a novel labyrinth seal-type centrifugal water pump, in particular to a centrifugal water pump with a seal device located between an impeller and a pump body and provided, which belongs to the technical field of water pumps. Clearance fit is adopted by an impeller mouth ring and a rubber ring of the water pump, and when the impeller rotates at a high speed, a water film is formed between the impeller mouth ring and the rubber ring, thus, not only is a seal effect performed, but also the original frictional resistance is eliminated, thereby, the efficiency of the water pump is improved, and the service life of the water pump is prolonged. Simultaneously, as the processing accuracy of the impeller mouth ring of the water pump is low, the manufacturing cost is also reduced. As the rubber ring and the impeller mouth ring of the water pump are in the clearance fit, the assembly is easier, more convenient and rapid.
Description
Technical field
The utility model relates to a kind of water pump, and the concrete Centrifugal water pump that relates to have seal arrangement between the impeller and the pump housing belongs to the pump technology field.
Technical background
Parameters such as the suction journey of Centrifugal water pump, lift, efficient are subjected to the influence of various factors, and the choma of water pump vane and the sealing between the pump housing are important factors.At present, the domestic patent No. is that the scheme of the novel water pump of ZL200520092314.5 is to be placed between water pump body and the impeller mouth wheel with rubber ring, water pump body and rubber ring are to closely cooperate, rubber ring and impeller port ring also closely cooperate, though play seal action like this, installation complexity, the processing cost height of impeller port ring, rubber ring inefficacy easy to wear and working resistance are big thereby working life water pump is short.
Summary of the invention
The utility model is the defective that remedies above-mentioned technology, provides that a kind of good seal performance, processing cost are low, easy for installation, the labyrinth seal formula novel centrifugal water pump of long service life.
The technological scheme that model utility adopts is: labyrinth seal formula novel centrifugal water pump is the front end that the rubber ring of L type places water pump body and impeller port ring with section, is to closely cooperate between rubber ring and the water pump body, and rubber ring and impeller port ring are Spielpassung; When the impeller high speed rotating, form moisture film between rubber ring and the impeller port ring, thereby reach the effect of sealing.
Described rubber seal ring and impeller port ring Spielpassung can be in Spielpassung by two faces, also can be in Spielpassung by a face.
Described seal ring skeleton, material adopts steel.
The beneficial effects of the utility model are: the impeller port ring of water pump and rubber ring adopt Spielpassung, during the impeller high speed rotating, form moisture film between the two, both played sealing effect, eliminate original surface friction drag again, thereby improved the efficient of water pump, prolonged the working life of water pump.The machining accuracy of water pump vane choma is low simultaneously, and manufacture cost decreases.Because rubber ring and water pump vane choma are Spielpassung, and be more easy and convenient during assembling, rapidly.
Description of drawings
Fig. 1 is the local structure for amplifying schematic representation of labyrinth seal formula novel centrifugal water pump.
Among the figure, 1, centrifugal pump body 2, rubber seal ring 3, impeller 4, seal ring Steel Skeleton.
Embodiment
In the accompanying drawings, be interference fit between centrifugal pump body 1 and the seal ring 2, be Spielpassung between rubber seal ring 2 and the impeller port ring 3.When impeller 3 high speed rotating, the AB face of rubber seal ring 2, BC face form moisture film and play seal action, and do not have surface friction drag between the two with the DE face of impeller 3, EF face respectively.In addition, indeformable for the face shaping that guarantees seal ring 2, Steel Skeleton 4 is housed in seal ring does support.
Claims (3)
1. labyrinth seal formula novel centrifugal water pump adds a rubber seal ring between the pump housing and water wheels, it is characterized in that: pump body and rubber ring are interference fit, is Spielpassung between rubber ring and the impeller port ring.
2. labyrinth seal formula novel centrifugal water pump according to claim 1 is characterized in that described rubber seal ring and impeller port ring Spielpassung, can be in Spielpassung by two faces, also can be in Spielpassung by a face.
