Abstract
The invention relates to a centrifugal pump structure, in particular to a single-stage double-suction centrifugal water pump. The single-stage double-suction centrifugal water pump comprises a pump body, a pump cover is arranged above the pump body, a spindle is arranged between the pump body and the pump cover in a penetrating mode, one end of the spindle is connected with a motor, the spindle is provided with two bearing brackets, two shaft sleeves and an impeller, the outer portion of each shaft sleeve is provided with a filler body, a filler ring is arranged between each shaft sleeve and the corresponding filler body, the pump cover is provided with a water outlet, the water outlet position of the pump cover is connected with a water pipe connector, and the two water outlet ends of the water pipe connector are connected with water pipes respectively; each filler body is provided with a liquid channel, the water inlet end of each liquid channel is connected with the water outlet end of the corresponding water pipe, and each filler ring is provided with a through hole communicated with the water outlet end of the corresponding liquid channel. By means of the design, self circulation is achieved, the single-stage double-suction centrifugal water pump does not need to be externally connected with tap water, the cost is reduced, and filler seals and the spindle are cooled.
Description
Technical field
The present invention relates to centrifugal pump structure.
Background technique
Existing single-stage double-suction clear water centrifugal pump mainly comprises the pump housing, the top of the pump housing arranges pump cover, a main shaft is placed between the pump housing and pump cover, one end of main shaft connects motor, main shaft is arranged two bearing bracket stands, two axle sleeves and an impeller, two bearing bracket stands are connected with the two ends of the pump housing respectively, two axle sleeves are arranged between two bearing bracket stands, impeller to be arranged between two axle sleeves and to be arranged in the pump housing and pump cover, each axle sleeve arranges filling body outward respectively, between each axle sleeve and corresponding filling body, arrange packing ring respectively.Due to temperature arrising caused by friction between the main shaft of centrifugal pump, axle sleeve, filling body, fragile pump, needs cooling, usually adopts the mode of external tap water, this mode waste water resource, increases cost.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of capable of self-circulating single-stage double-suction clear water centrifugal pump carrying out cooling is provided.
The object of the present invention is achieved like this: single-stage double-suction clear water centrifugal pump, comprise the pump housing, the top of the pump housing arranges pump cover, a main shaft is placed between the pump housing and pump cover, one end of main shaft connects motor, main shaft is arranged two bearing bracket stands, two axle sleeves and an impeller, two bearing bracket stands are connected with the two ends of the pump housing respectively, two axle sleeves are arranged between two bearing bracket stands, impeller to be arranged between two axle sleeves and to be arranged in the pump housing and pump cover, each axle sleeve arranges filling body outward respectively, between each axle sleeve and corresponding filling body, packing ring is set respectively, described pump cover sets out the mouth of a river, the pump cover connecting water pipe joint of water outlet, two waterexit ends of water pipe adapter connect a water pipe respectively, each filling body arranges fluid passage respectively, and the feed-water end of each fluid passage is connected with the waterexit end of corresponding water pipe respectively, each packing ring is arranged respectively the through hole be connected with the waterexit end of corresponding fluid passage.
The present invention is by above design, in through hole → pump cover on fluid passage → packing ring in water → water outlet → water pipe adapter → water pipe → filling body in pump cover, form circulation, without the need to external tap water, not only save cost, and packing seal, main shaft have been cooled.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present invention.
Fig. 2 is A portion enlarged view in Fig. 1.
In figure, 1 pump housing, 2 water pipes, 3 water pipe adapters, 4 water outlets, 5 pump covers, 6 impellers, 7 filling bodies, 8 main shafts, 9 bearing bracket stands, 10 motors, 11 fluid passages, 12 axle sleeves, 13 packing rings, 14 through holes.
Embodiment
As shown in Figure 1, 2, the present invention mainly comprises the pump housing 1, and the top of the pump housing 1 arranges pump cover 5, pump cover 5 sets out the mouth of a river 4, and the pump cover 5 connecting water pipe joint 3 at water outlet 4 place, two waterexit ends of water pipe adapter 3 connect a water pipe 2 respectively.A main shaft 8 is placed between the pump housing 1 and pump cover 5, one end of main shaft 8 connects motor 10, main shaft 8 is arranged two bearing bracket stands 9, two axle sleeves 12 and an impeller 6, two bearing bracket stands 9 are connected with the two ends, left and right of the pump housing 1 respectively, two axle sleeves 12 are arranged between two bearing bracket stands 9, impeller 6 to be arranged between two axle sleeves 12 and to be arranged in the pump housing 1 and pump cover 5, each axle sleeve 12 is outer arranges filling body 7 respectively, each filling body 7 arranges fluid passage 11 respectively, the feed-water end of each fluid passage 11 is connected with the waterexit end of corresponding water pipe 2 respectively, between each axle sleeve 12 and corresponding filling body 7, packing ring 13 is set respectively, each packing ring 13 is arranged respectively the through hole 14 be connected with the waterexit end of corresponding fluid passage 11.
