Abstract
The utility model relates to a self press water diversion centrifugal pump with a single casing body and two impellers, which comprises a pump casing, a base, a pump shaft, impellers, and a manual water diversion device. The pump casing is positioned on the base. The pump shaft is provided with two impellers. The right end of the pump casing is connected with a water inlet tee joint through a flange. One end of the water inlet tee joint is connected with the manual water diversion device. The utility model has the characteristics of simple manufacturing techniques, low manufacturing cost and use cost, convenient installation and operation, good waterproof tightness, large water quantity, and high work efficiency.
Description
The utility model relates to a kind of centrifugal pump, and especially a kind of mono-hull bilobed wheel is from pressing the diversion centrifugal pump.
At present, the various small-sized centrifugal pump that uses in the society, because its structure limits ubiquity water flow little, efficient is low, and lift is short, and water leakage phenomenon is serious, and service behaviour is stable inadequately, and working life is short, the defective that hazard rate is high.
The purpose of this utility model is to provide a kind of manufacturing process simple, manufacture cost and user cost are low, easy to install and use, the leakproof water sealing property is good, the water yield is big, high working efficiency, long service life, the low mono-hull bilobed wheel of hazard rate is from pressing the diversion centrifugal pump.
Task of the present utility model takes following technological scheme to realize, comprise pump case, base, pump shaft, impeller and manual water diversion apparatus, pump case is seated on the base, it is characterized in that: be positioned with the water-stop sheet that has the center water channel in pump case central vertical position and along the inner walls periphery, the pump shaft that is supported by the bearing pack external member is arranged in housing central horizontal location positioning, this bearing pack external member connects the end cap flange by a left side that has flange and is connected with the pump case left end, one end of pump shaft places the right side of water-stop sheet by the center water channel of water-stop sheet, on the pump shaft of water-stop sheet both sides, be positioned with left-hand impeller and dextrad impeller respectively, left side, the upper end of pump case and the top that is positioned at the left-hand impeller are provided with the water outlet of flanged dish, the pump case right-hand member connects the end cap flange by the right side that has flange and is connected with into water threeway, and the water inlet threeway links to each other with manual water diversion apparatus.
The utility model is owing to adopt mono-hull, adopt flange to be connected between water pump and the pipeline, make preparation process simple, the rate of fault of water pump is low, long service life, a left side, one end of right end cap flange is respectively equipped with flange, anti-water-leaking property can be strengthened, owing to be provided with water-stop sheet and bilobed wheel in the pump housing, two chambers about water-stop sheet is divided into the housing inner chamber are when pump shaft drives the bilobed wheel rotation simultaneously, the rotation of dextrad impeller makes the right chamber of housing form negative pressure, the rotation of left-hand impeller makes housing left chamber form malleation, has increased the suction journey and the lift of pump, thereby has improved drawing water and transmission efficiency of pump.
The utility model is described further as follows below in conjunction with accompanying drawing:
Accompanying drawing is a structural representation of the present utility model.
In the accompanying drawings, 1 is pump case, and 2 is the bearing pack external member, 3 is pump shaft, and 4 is that a left side connects the end cap flange, and 5 is the left-hand impeller, 6 is the outlet pipe flange, and 7 is water-stop sheet, and 8 is belt pulley, 9 is the dextrad impeller, and 10 is the right end cap flange that connects, and 11 is manual water diversion apparatus, 12 are the water inlet threeway, and 13 is suction sleeve, and 14 are the diversion handle, 15 is base, and 16 is the center water channel, and 17 is flange.
With reference to the accompanying drawings, pump case 1 is seated on the base 15, in pump case 1 central vertical position and be positioned with the water-stop sheet 7 of band center water channel 16 along the inner walls periphery, be positioned with the pump shaft 3 that supports by bearing pack external member 2 in housing 1 horizontal central position, bearing pack external member 2 connects end cap flange 4 by a left side that has flange 17 and is connected with pump case 1 left end, one end of pump shaft 3 places the right side of water-stop sheet 7 by the center water channel 16 of water-stop sheet 7, on the pump shaft 3 of water-stop sheet 7 both sides, be positioned with left-hand impeller 5 and dextrad impeller 9 respectively, the other end of pump shaft 3 is provided with the belt pulley 8 by drive power source, left side, the upper end of pump case 1 and the top that is positioned at left-hand impeller 5 are provided with flanged 6 water outlet, pump case 1 right-hand member connects end cap flange 10 by the right side that has flange 17 and is connected with into water threeway 12, the upper end of water inlet threeway 12 is provided with manual water diversion apparatus 11, and the lower end of water inlet threeway 12 is connected with suction sleeve 13.In use, suction sleeve 13 is placed the water source, with belt pulley 8 and source motivation (motor, diesel engine etc.) arbor wheel links to each other, utilize manual water diversion apparatus 11, press diversion handle 14 to make in water threeway 12 chambeies and pump case 1 inner chamber forms the negative-pressure vacuum state by rising repeatedly, water flows into along suction sleeve, to intake threeway 12 and pump case 1 inner chamber is full of water, start the source motivation this moment, the source motivation drives pump shaft 3 by belt pulley 8 and rotates, pump shaft 3 drives two impellers and rotates synchronously, 9 rotations of dextrad impeller make pump case 1 right chamber form negative pressure, and 5 rotations of left-hand impeller make pump case 1 left chamber form malleation, make water constantly enter water pump along suction sleeve 13, discharge from outlet pipe the pressurization back, thereby realize task of the present utility model.
