Abstract
The utility model discloses an impeller and auxiliary impeller seal structure for a pump. Seal edges are arranged on the circumference of the shroud portion of the impeller or the auxiliary impeller, the tail and the head of every seal edge are connected to form a seal ring. According to the technical scheme of the impeller and auxiliary impeller seal structure for the pump, the seal edges are arranged on the circumference of the shroud portion of the impeller or the auxiliary impeller, the open-type shroud portion of the impeller or the auxiliary impeller is changed into a seal type, so that the sealing effect is enhanced, the impeller or the auxiliary impeller is better protected, and the service life of the impeller and the auxiliary impeller is prolonged.
Description
Technical field
The utility model relates to the impeller of pump sub-propeller, especially the sealing configuration of impeller of pump sub-propeller.
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.Pump impeller or sub-propeller partly are open type at integral shroud at present, and sealing effect is bad especially, after work a period of time impeller or sub-propeller are had serious damage like this.
Summary of the invention
Technical problem to be solved in the utility model provides the impeller of pump sub-propeller sealing configuration of a kind of good sealing effect protection impeller or sub-propeller.
For solving above technical problem, the utility model provides following technological scheme:
The utility model provides a kind of impeller of pump sub-propeller sealing configuration, at described impeller of pump or sub-propeller integral shroud part edge the sealing edge is arranged all circumferentially, and described sealing is connected to a seal ring along head and the tail.
The utility model provides the beneficial effect of technological scheme to be:
Adopt technological scheme provided by the utility model; circumferentially the sealing edge is arranged all at the described impeller of pump of institute or sub-propeller integral shroud part edge, will make it become sealed type by open type, strengthened sealing effect; better protection impeller or sub-propeller, increased the life time of impeller and sub-propeller.
Description of drawings
Fig. 1 is the structural representation on the utility model impeller of pump sub-propeller sealing edge.
Referring to Fig. 1: 1 is the sealing edge, and 2 is impeller.
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, impeller of pump sub-propeller sealing configuration described in the utility model, described impeller of pump with regard to 1 or sub-propeller integral shroud part along circumferentially sealing all being arranged along 2, described sealing is along being connected to from beginning to end a seal ring.Adopt technological scheme provided by the utility model; described impeller of pump with regard to 1 or sub-propeller integral shroud part along circumferentially sealing all being arranged along 2, will make it become sealed type by open type, strengthened sealing effect; better protection impeller 1 or sub-propeller, increased the life time of impeller 1 and sub-propeller.
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.
Claims (1)
1. impeller of pump sub-propeller sealing configuration is characterized in that: described impeller of pump (1) or sub-propeller integral shroud part are along circumferentially all having sealing along (2), and described sealing is along being connected to from beginning to end a seal ring.
