Embodiment
A kind of peripheral pump, comprise the pump housing 1, pump cover 2, swirl vanes 3, swirl vanes 3 is between the pump housing 1 and pump cover 2, the ring runner 4 coordinated with swirl vanes 3 is provided with between the pump housing 1 and pump cover 2, the pump housing 1 is provided with the suction port 5 and exhaust port 6 that are communicated with ring runner 4, and ring runner 4 is provided with dividing plate 7, and dividing plate 7 keeps apart described suction port 5 and exhaust port 6, the pump housing 1 is provided with the impurity discharging port 8 of some connection ring runners 4, and impurity discharging port 8 shutoff has dismountable plug 8a.When after peripheral pump work a period of time, a certain amount of solid granule is often piled up at inner position, ring runner 4 dead angle, if discharged not in time, the easy work affecting peripheral pump, by dismounting plug 8a, makes impurity discharging port 8 be in communication with the outside, pour water in the pump housing 1 again and start peripheral pump, by the impact force of water, the solid particle at ring runner 4 dead angle place is washed away, avoid the trouble of dismounting pump cover 2, facilitate rapid-maintenance water pump.
Wherein, impurity discharging port 8 is provided with internal thread, and plug 8a is provided with outside thread, and plug 8a is threaded in impurity discharging port 8.Plug 8a can adopt general hexagon head bolt, without the need to oneself processing, arranges the effect that seal ring 8b plays anti-leak between the head of hexagon head bolt and the pump housing 1.The mode adopting screw thread to install, removes and installs all more convenient.
Wherein, swirl vanes 3 side coordinates with pump cover 2, swirl vanes 3 opposite side coordinates with the pump housing 1, setting swirl vanes 3 is the first fitting surface 9 with the fitting surface of pump cover 2, setting swirl vanes 3 is the second fitting surface 10 with the fitting surface of the pump housing 1, first fitting surface 9 and the second fitting surface 10 are respectively equipped with step-like positioning part, described positioning part comprises being arranged on swirl vanes 3 end face caves in 11 and protruding 12, depression 11 is positioned near swirl vanes 3 end face center, and protruding 12 opposing recesses 11 are away from swirl vanes 3 end face center.Positioning part is set and better can corrects dynamic balancing when swirl vanes 3 is rotated, ensure that pump cover 2, the pump housing 1 are concentric with swirl vanes 3 three, reduce noise when peripheral pump works and rock.Accordingly, pump cover 2 is arranged at respectively the depression 11 and protruding 12 that swirl vanes 3 end face coordinates, the projection 12 on the corresponding pump cover 2 of the depression 11 namely in swirl vanes 3 pump housing 1 is also like this.
Wherein, between depression 11 and protruding 12, be provided with transitional surface, the vertical surface 14 of to be the transitional surface on the fitting surface 10 of plane of inclination 13, second be vertical swirl vanes 3 end face of the transitional surface on the first fitting surface 9.Swirl vanes 3 first coordinates with the pump housing 1 when assembling, now vertical surface 14 can play guiding and ensure the effect concentric with rotating shaft, when being then pressed into pump cover 2, due to the effect of plane of inclination 13, plane of inclination 13 on pump cover 2 extrudes mutually with the plane of inclination 13 in swirl vanes 3, produce radial component, further regulating action is played to the concentric correction of swirl vanes 3.
Wherein, swirl vanes 3 end face also offers some dynamic balancing hole 3a.If there is rotation imbalance, easily there are larger vibration and wearing and tearing in swirl vanes 3, arranges dynamic balancing hole 3a and can improve this phenomenon, dynamic balancing hole 3a can also arrange internal thread, carries out more excellent adjustment to install some dynamic balance weights additional.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
