Abstract
The utility model discloses a horizontal type double-suction axially split pump, and relates to the technical field of pump design. The horizontal type double-suction axially split pump comprises a pump body, a pump cover, a pump shaft and an impeller which is arranged on the pump shaft. The pump shaft and the pump body are fixed through a bearing body. A shaft sleeve is arranged on the outer side of the pump shaft. The pump cover and the pump body are matched and then form a cavity with the shaft sleeve. The pump cover and the pump body are of an up-and-down split-merging type structure. The pump cover and the pump body are matched to be arranged on the outer side of the pump shaft in a sleeved mode. A suction inlet and a discharging opening are formed in the pump body. The impeller is a three-dimensional throttling impeller. Auxiliary impellers are symmetrically arranged at the two ends of the impeller respectively, and each auxiliary impeller is arranged corresponding to a water flow channel of the impeller. The horizontal type double-suction axially split pump is high in self-absorption degree, small in vibration, high in efficiency, capable of prolonging the service life, and suitable for the fields of water supply systems or irrigation and industrial application or pipeline conveying or the like.
Description
Technical field
The utility model relates to the design field of pump.
Background technique
The purposes of middle-opening pump is a lot, such as the water intaking for water system, irrigation, commercial Application or Pipeline transport, water supply, supercharging, draining, water intaking, water and Crude Oil Transportation, desalination of sea water, water circulation, fire-fighting etc.At present, traditional horizontal Double entry middle-opening pump carries clear water and physicochemical properties to be similar to the liquid of water for supplying, and suction lift is not enough, and vibration is large, efficiency is low, and operating life is short.
Model utility content
The utility model object is for above problem, provide a kind of self-priming degree high, vibrate horizontal Double entry middle-opening pump little, that efficiency is high and the life-span improves.
The utility model comprises the pump housing, pump cover, pump shaft, is installed in the impeller on pump shaft; Pump shaft and the pump housing are fixed by bearing support; Pump shaft arranged outside has axle sleeve; After pump cover and the pump housing coordinate and between axle sleeve, form cavity; Described pump cover and the pump housing are upper and lower separating-closing type structure; Described pump cover and pump housing engage sleeves are in the outside of pump shaft; Suction port, discharge opening are set on the described pump housing; Described impeller is ternary throttling impeller; Two ends at described impeller are symmetrical arranged respectively sub-propeller, described each sub-propeller respectively with the corresponding setting of flow channel of impeller.
The utility model adopts ternary throttling impeller and increases a pair of sub-propeller, and efficiency increases 2-3%, and suction lift improves 75%, has reduced cavitation.In wider flow (peak rate of flow can reach 15000m3/h) scope, there is very high operational efficiency (reaching more than 80%), can reduce operating cost, select lower-powered motor.And reduced noise and vibration, extended the working life of equipment, more economically environmental protection.Because suction port and discharge opening are all on the pump housing below pump shaft line, during maintenance, do not need dismounting water inlet and rising pipe, just can carry out maintenance and inspection to the inner components of pump.The utility model self-priming degree is high, it is little to vibrate, efficiency is high and the life-span improves, and is applicable to the fields such as water system, irrigation, commercial Application or Pipeline transport.
