Abstract
The utility model discloses a single-stage double-suction clean water centrifugal pump, and relates to a structure of a centrifugal pump. The single-stage double-suction clean water centrifugal pump comprises a pump body, wherein a pump cover is arranged above the pump body, a main shaft is arranged between the pump body and the pump cover in a penetrated mode, one end of the main shaft is connected with a motor, two bearing supports, two shaft sleeves and an impeller are arranged on the main shaft, a padding body is arranged outside each shaft sleeve, a padding ring is arranged between each shaft sleeve and the corresponding padding body, a water outlet is formed in the pump cover, a water pipe connector is connected to the portion, at the water outlet, of the pump cover, and the two water outflow ends of the water pipe connector are respectively connected with one water pipe; a liquid channel is arranged on each padding body, the water inflow end of each liquid channel is connected with the water outflow end of the corresponding water pipe, and a through hole communicated with the water outflow end of the corresponding liquid channel is formed in each padding ring. Due to the design of the single-stage double-suction clean water centrifugal pump, self circulation is formed, external tap water does not need to be led in, and therefore not only is cost saved, but also cooling is performed on padding sealing and the main shaft.
Description
Technical field
The utility model 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, place a main shaft between the pump housing and pump cover, one end of main shaft connects motor, two bearing bracket stands, two axle sleeves and an impeller are set on main shaft, 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 is arranged between two axle sleeves and is arranged in the pump housing and pump cover, each axle sleeve arranges respectively filling body outward, between each axle sleeve and corresponding filling body, packing ring is set respectively.Due to temperature arrising caused by friction between the main shaft of centrifugal pump, axle sleeve, filling body, fragile pump, need cooling, usually adopts the mode of external tap water, and this mode waste water resource increases cost.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of capable of self-circulating cooling single-stage double-suction clear water centrifugal pump that carries out is provided.
The purpose of this utility model is achieved in that the single-stage double-suction clear water centrifugal pump, comprise the pump housing, the top of the pump housing arranges pump cover, place a main shaft between the pump housing and pump cover, one end of main shaft connects motor, two bearing bracket stands are set on main shaft, 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 is arranged between two axle sleeves and is arranged in the pump housing and pump cover, each axle sleeve arranges respectively filling body outward, between each axle sleeve and corresponding filling body, packing ring is set respectively, set out the mouth of a river on described pump cover, the pump cover connecting water pipe joint of water outlet, two waterexit ends of water pipe adapter connect respectively a water pipe, fluid passage is set respectively on each filling body, and the feed-water end of each fluid passage is connected with the waterexit end of corresponding water pipe respectively, and the through hole be connected with the waterexit end of corresponding fluid passage is set respectively on each packing ring.
The utility model is by above design, in through hole → pump cover on fluid passage → packing ring in water → water outlet in pump cover → water pipe adapter → water pipe → filling body, form circulation, without external tap water, not only saved cost, and packing seal, main shaft have been cooled.
