Abstract
The utility model discloses a seal cavity type seal structure for a pump. The seal cavity type seal structure for the pump comprises a pump casing, an impeller and an impeller protecting board, and seal cavities are formed among the pump casing, the impeller and the impeller protecting board. Two sides of the impeller are recessed inwards, and recesses form two seal cavities among the pump casing, the impeller and the impeller protecting board. According to the technical scheme of the seal cavity type seal structure for the pump, two sides of the impeller are recessed inwards, and the recesses form two seal cavities among the pump casing, the impeller and the impeller protecting board, so that the sealing effect is improved greatly, and the problems that external leakage of the pump pollutes the environment and internal leakage of the pump causes inefficiency are solved.
Description
Technical field
The utility model relates to a kind of pump, and especially pump is with sealing the cavate sealing configuration.
Background technique
Water pump vane rotates by motor drives, makes the middle vacuum that produces of impeller, and water will flow into (being that impeller constantly sucks water on the surface) toward the vacuum place, and water is discharged water by the impeller of rotation at a high speed more then, plays the effect of a promotion water.The effect of centrifugal pump impeller: be that the mechanical energy of prime mover is directly passed to liquid, mainly increase static energy with static energy and the kinetic energy that increases liquid.At present pump impeller is sealed at both ends does not nearly all have a measure, just regulates by gap length, and sealing effect is poor, cause pump inside and outside reveal serious, the external leakage befouling environment, internal leakage causes pump efficiency low.
The model utility content
Technical problem to be solved in the utility model provides a kind of pump with sealing cavate sealing configuration, improves sealing effect, solves that pump is inside and outsidely revealed serious, external leakage befouling environment, internal leakage causes the low problem of pump efficiency.
For solving above technical problem, the utility model provides following technological scheme:
The utility model provides a kind of pump with sealing the cavate sealing configuration, and this pump comprises pump case, impeller and impeller backplate with sealing cavate sealing configuration, between described pump case, impeller and three parts of impeller backplate Seal cage is arranged.Described impeller both sides cave inward, and this is recessed in and forms two Seal cages between pump case, impeller and the impeller backplate.
The utility model provides the beneficial effect of technological scheme to be:
Adopt technological scheme provided by the utility model, the impeller both sides are caved inward, this is recessed in and forms two Seal cages between pump case, impeller and the impeller backplate, can improve sealing effect greatly like this, has solved pump external leakage befouling environment and internal leakage and has caused the low problem of pump efficiency.
Description of drawings
Fig. 1 is the general construction schematic representation of the utility model pump with the sealing of sealing cavate.
Referring to Fig. 1: 1 is pump case, and 2 is impeller, and 3 is backplate, and 4 is Seal cage.
Embodiment
For making purpose of the present invention, technological scheme and beneficial effect clearer, below in conjunction with accompanying drawing will embodiment of the present invention is described further in detail.
As shown in Figure 1, pump described in the utility model comprises pump case 1, impeller 2 and impeller backplate 3 with sealing cavate sealing configuration, this pump with sealing cavate sealing configuration, between described pump case 1, impeller 2 and 3 three parts of impeller backplate Seal cage 4 is arranged.Described impeller 2 both sides cave inward, and this is recessed in and forms two Seal cages 4 between pump case 1, impeller 2 and the impeller backplate 3.Adopt technological scheme provided by the utility model, impeller 2 both sides are caved inward, this is recessed in and forms two Seal cages 4 between pump case 1, impeller 2 and the impeller backplate 3, can improve sealing effect greatly like this, has solved pump external leakage befouling environment and internal leakage and has caused the low problem of pump efficiency.
The utility model protection domain is not limited to above-described embodiment, and everything all falls within protection scope of the present invention according to the apparent technology distortion that the technology of the present invention principle is done.
