Abstract
The utility model relates to a sealing device for a water inlet section of a water pump, which relates to a sealing structure for water inlet sections. The utility model is mainly composed of the water inlet section arranged on a pump body and an impeller. The utility model is characterized in that a circular sealing groove is arranged on the pump body which is the combination position of the water inlet section and the impeller; the corresponding position of the impeller is provided with a circle of convex ring which can extend into the sealing groove; the water inlet section forms combined type sealing, and thereby, the sealing performance between the impeller and the water inlet section of the pump body is effectively increased. The utility model has the effect of good sealing performance and simple structure, and meanwhile, the normal rotation of the impeller can not be affected. The utility model effectively enhances the suction lift, the lift, the flow rate, and the efficiency of the water pump.
Description
Technical field
The utility model is a kind of improved water pump gland, particularly a kind of device that improves water pump inlet segment position sealing configuration.
Background technique
The sealing direct relation of water pump the lift and the pumping load of water pump, used water pump is provided with seal ring in the junction of impeller and inlet segment now, owing to be plane contact between seal ring and the impeller, occur inevitably leaking, gas leak phenomenon, directly influence the service behaviour of water pump.
Summary of the invention
The purpose of this utility model is to provide a kind of water pump inlet segment seal arrangement of good seal performance.
The utility model is achieved in that
Water pump inlet segment seal arrangement, mainly form by the inlet segment and the impeller that are positioned on the pump housing, it is characterized in that: on the pump housing of inlet segment and impeller junction, have the seal groove of a circle, be provided with one in the relevant position of impeller and enclose the bulge loop that can stretch in the above-mentioned seal groove.
After the utility model adopts said structure, owing to be provided with seal groove that is exclusively used in sealing and the bulge loop that cooperates with it in the pump housing and junction between the impeller, make the casing ring place form compound sealing, effectively improved the sealability between impeller and the pump housing inlet segment, have good seal performance, effect simple in structure, do not influence the normal rotation of impeller simultaneously.Effectively improved the raising of suction journey, lift, flow and the efficient of water pump.
Description of drawings
Accompanying drawing is a kind of structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
In the accompanying drawing, 1 is that inlet segment, 2 is that impeller, 3 is that seal groove, 4 is bulge loop.
As shown in drawings, the utility model is a kind of new type sealing device that improves the inlet segment sealing configuration, is mainly converted by raw water pump, and water pump comprises the pump housing and impeller 2, and the pump housing is provided with inlet segment 1.On the pump housing of inlet segment 1 and impeller 2 junctions, have the seal groove 3 of a circle, be provided with one in the relevant position of impeller 2 and enclose the bulge loop 4 that can stretch in the above-mentioned seal groove 3.Bulge loop 4 high speed rotating in seal groove 3 during use makes the Mi Jinshuiduanchu of the pump housing form a compound sealing, has effectively improved sealability.
Claims (1)
