Abstract
The two entrance energy-saving multi-stage centrifugal pumps of self balancing, the pump shaft of this centrifugal pump is supported by left and right bearing support, and Spit Section is arranged on the middle part of pump shaft, its both sides are symmetrically installed with respectively stator successively, impeller, stage casing and inlet segment, all parts is fastenedly connected as a whole by turnbuckle; Between stator and impeller, be designed to twoport ring structure, the outer rim contacting point of the inlet of inlet segment and impeller adopts single suction maze-type structure.This pump is realized the autobalance of axial force, has extended the working life of pump, has reduced customer equipment maintenance cost; Due to the employing of twoport ring and single suction maze-type structure, greatly increased the sealability of pump, reduced liquid leakage, reduced volumetric loss, improved the volumetric efficiency of pump, increased the self balancing effect of pump, improved pump efficiency.In a word, this multistage centrifugal pump component is few, simple in structure, and cost is low, long service life, and good seal performance, flow is large, and efficiency is high, and running state is very steadily reliable.
Description
One, technical field
The utility model relates to a kind of multistage centrifugal pump, the two entrance energy-saving multi-stage centrifugal pumps of especially a kind of self balancing.
Two, background technique
Current, the multistage centrifugal pump of application, it is all single-suction centrifugal pump, its structure is to only have an entrance, the equidirectional mode of arranging in turn of all impellers is arranged on a pump shaft, and pump in use can produce axial force, to the processing of balancing axial thrust, conventionally adopts Balance disc or balancing drum to carry out balance, but cannot eliminate axial force completely, remaining axial force is born by bearing at all.In use, bearing bears larger axial force and easily damages pump, and balanced controls wearing and tearing also can cause other rotor component wearing and tearing, thereby affects the normal service life of pump, often changes the device maintenance expense that wear-out part has also increased user.Single entrance single-suction multistage centrifugal pump has limited the flow of pump, cannot realize large flow.Also have, its inlet segment of various centrifugal pumps of application directly contacts with the outer rim of the inlet of impeller now, also there is no seal arrangement between impeller and stator, reasons in structure makes the poor sealing performance of pump, liquid amount of leakage is large, causes the volumetric efficiency of pump low, has also affected the self balancing effect of pump.
Three, summary of the invention
In order to solve the deficiencies in the prior art, the purpose of this utility model is to provide the two entrance energy-saving multi-stage centrifugal pumps of a kind of self balancing.
The technological scheme that realizes the purpose of this utility model employing is: this centrifugal pump is mainly comprised of pump shaft, left and right bearing support, inlet segment, impeller, stator, stage casing and Spit Section; Pump shaft is supported by left and right bearing support, and Spit Section is arranged on the middle part of pump shaft, and its both sides are symmetrically installed with respectively stator successively, impeller, and stage casing and inlet segment, all parts is fastenedly connected as a whole by turnbuckle; Between stator and impeller, be designed to twoport ring structure, the outer rim contacting point of the inlet of inlet segment and impeller adopts single suction maze-type structure.
The utility model advantage is compared with prior art: the one, because whole water pump is in a symmetrical arrangement centered by the water outlet of the Spit Section of pump, thereby realize the autobalance of axial force, damage of components and the wearing and tearing of having avoided existing multistage centrifugal pump to produce in operation process for realizing balancing axial thrust, extend the working life of pump, reduced customer equipment maintenance cost.The 2nd, owing to adopting between stator and impeller, be designed to twoport ring structure, inlet segment and impeller contacting point adopt single suction maze-type structure, greatly increased the sealability of pump, reduced liquid leakage, reduced volumetric loss, improve the volumetric efficiency of pump, increased the self balancing effect of pump, improved pump efficiency.In a word, it is few, simple in structure that this multistage centrifugal pump and other multistage centrifugal pumps are compared part, and cost is low, long service life, and good seal performance, flow is large, and efficiency is high, and running state is very steadily reliable.
Four, accompanying drawing explanation
Fig. 1 is the sectional structure chart of the two entrance energy-saving multi-stage centrifugal pumps of the utility model self balancing.
Fig. 2 is the A place enlarged view of the two entrance energy-saving multi-stage centrifugal pump Fig. 1 of the utility model self balancing.
Fig. 3 is the B place enlarged view of the two entrance energy-saving multi-stage centrifugal pump Fig. 1 of the utility model self balancing.
Five, embodiment
In the accompanying drawings, the two entrance energy-saving multi-stage centrifugal pumps of the utility model self balancing; Mainly by pump shaft, left and right bearing support, inlet segment, impeller, stator, stage casing and Spit Section, formed; Pump shaft 1 is by being supported by left bearing body 2 and right bearing body 9, and Spit Section 7 is arranged on the middle part of pump shaft 1, and its both sides are symmetrically installed with respectively stator 5 successively, impeller 4, and stage casing 8 and inlet segment 3, all parts is fastenedly connected as a whole by turnbuckle.Whole water pump is in a symmetrical arrangement centered by the water outlet of the Spit Section of pump, thereby realize the autobalance of axial force, damage of components and the wearing and tearing of having avoided existing multistage centrifugal pump to produce in operation process for realizing balancing axial thrust, extend the working life of pump, reduced customer equipment maintenance cost.4, stator 5 and impeller are designed to twoport ring structure (seeing Fig. 2), and inlet segment 3 adopts single suction maze-type structure (seeing Fig. 3) with the outer rim contacting point of the inlet of impeller 4.The employing of twoport ring and single suction maze-type structure, has increased the sealability of pump greatly, has reduced liquid leakage, has reduced volumetric loss, has improved the volumetric efficiency of pump, has increased the self balancing effect of pump, has improved pump efficiency.
