Compared with existing double-suction centrifugal pumps, the utility model has the advantages of simple manufacturing techniques, small ground occupation, and low cost. The structure can enlarge the use range of double-suction centrifugal pumps.
Description
The utility model belongs to the pump class, relates to a kind of combined type single-stage and multistage double-suction centrifugal pump.
Existing double suction pump adopts the middle open type worm frame, and impeller can be seen as by two back-to-back cast solids of impeller.Double suction pump is compared with single entry pump bigger flow, and comparing with mixed flow pump has higher lift, and therefore, using scope is wider.The advantage of existing double suction pump: structure is standardization, and volumetric loss is little, and the pump efficiency height overhauls more convenient; The defective of existing double suction pump, casting and processing technology complexity, the ability that sucts is relatively poor, adopts double supporting structure pump assembly floor space bigger, adopts in the scroll casing type opening structure to limit existing double suction pump and develops to the multipolarity direction.
The purpose of this utility model just provides a kind of standardization level height, and maintenance is convenient, and processing technology is simple, and the unit floor space is few, and it is good to suct performance, pump efficiency height, the double suction pump that can develop to the multipolarity direction.
The purpose of this utility model is achieved in that 1, adopts a kind of twin shaft to stretch motor is power, and the motor shaft extension can specially contain water pump spindle, also can adopt the standard shaft extension to connect with water pump spindle by coupling; 2, twin shaft is stretched the motor both sides respectively to connect a performance identical, and the work sense of rotation is opposite, the single entry pump that the axial force direction vector is opposite; 3, water pump import in both sides connects by the feed liquor three-way pipe, and outlet connects by the fluid three-way pipe.
In more detail, this double suction pump comprises compositions such as the pump housing, impeller, motor, and impeller is connected on the motor shaft, and impeller is in the pump housing.Motor is that twin shaft is stretched motor; The single entry pump performance that the motor both sides are made up of the pump housing, impeller etc. is identical, and the work sense of rotation is opposite, and the axial force direction vector is opposite; Both sides water pump import connects by the feed liquor three-way pipe, and outlet connects by the fluid three-way pipe.
Effect of the present utility model is embodied in: 1, adopting twin shaft to stretch motor is power, power consumpiton and the air channel noise having saved motor blower fan, fan housing, produced when having eliminated fan blade work, 2, two performances are identical, the work sense of rotation is opposite, the single entry pump that the axial force direction vector is opposite is arranged in the motor both sides, can save the axial thrust balancing devices of both sides single entry pump, eliminate this partial volume loss, improve pump efficiency; 3, adopt the single-stage double-suction pump of scroll casing type structure, the impeller inlet state is better than double-entry impeller, it is good to suct performance, 4, when adopting segmentation structure, can realize more easily that double suction pump develops to the multipolarity direction, enlarge the using scope of double suction pump, 5, the casting of the pump housing and impeller and processing technology are all fairly simple, processing cost is lower, 6, save the double supporting structure of water pump, not only can eliminate this part machinery and consume, reduce this part manufacture cost, and can reduce unit weight greatly, save the unit floor space, 7, only need to change a motor case and a side water pump vane, the sense of rotation of the pump housing etc. just can realize the change of existing pump type easily, parts standardization, generalization degree height, I﹠M is all more convenient.
