Abstract
The utility model relates to a kind of horizontal multi-stage centrifugal pump seal ring structure, comprise an intermediate body member, described intermediate body member is spliced by multiple medial section, an impeller is provided with in two adjacent medial section, by a seal ring seal between described impeller and described medial section, it is characterized in that, the end face of described seal ring relative to described impeller have at least two road annular grooves, be filled with a teflon pad in described second ring groove respectively, described teflon pad and described impeller are drive fit.By this, reduce leakage rate, improve sealing, improve the problem of water pump volumetric loss, thus increase pump efficiency.
Description
Technical field
The utility model relates to multistage centrifugal pump field, specifically a kind of horizontal multi-stage centrifugal pump seal ring structure.
Background technique
See Fig. 1, shown in figure is the widely used a kind of horizontal multi-stage centrifugal pump seal ring structure of current producer, liquid is from high side to low side runner, formation inter-stage leaks, because multistage pump has all multistage, the leakage rate that accumulation is got up will increase, and volumetric loss increases thereupon, thus causes pump efficiency to reduce.
Model utility content
The utility model object proposes a kind of novel horizontal type multi-stage pump centrifugal pump seal ring structure, overcomes the problems of the prior art.
To achieve these goals, the technical solution of the utility model is achieved in that a kind of horizontal multi-stage centrifugal pump seal ring structure, comprise an intermediate body member, described intermediate body member is spliced by multiple medial section, an impeller is provided with in two adjacent medial section, by a seal ring seal between described impeller and described medial section, it is characterized in that, the end face of described seal ring relative to described impeller have at least two road annular grooves, a teflon pad is filled with respectively in described second ring groove, described teflon pad and described impeller are drive fit.
Compared with prior art, the utility model has the advantage of, under the prerequisite not changing former main structure and mounting point, change seal ring structure and reduce leakage rate, reduce water pump volumetric loss, thus increase pump efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of prior art.
Fig. 2 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is elaborated.
Refer to Fig. 2, shown in figure is a kind of horizontal multi-stage centrifugal pump seal ring structure, comprise an intermediate body member 1, described intermediate body member is spliced by multiple medial section 2, an impeller 3 is provided with in two adjacent medial section 2, sealed by a seal ring 4 between described impeller 3 and described medial section 2, the end face of described seal ring 4 relative to described impeller 3 is formed with the annular groove of two roads along its circumference, be filled with a teflon pad in described second ring groove respectively, described teflon pad and described impeller are drive fit.Like this, make liquid there is certain resistance from high side to low side flowing, reduce its leakage rate, thus reduce volumetric loss increase pump efficiency.
Below only have expressed mode of execution of the present utility model, it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to utility model patent scope.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
