Abstract
The utility model discloses a kind of self balancing energy-saving multi-stage centrifugal pump, its structure characteristic is the first Spit Section of this pump, the middle part that Spit Section is arranged on pump shaft, on the pump shaft in the first left side, Spit Section, stator, impeller, stage casing, suction casing is installed from right to left successively; Stator, impeller, stage casing, the second suction casing are from left to right installed on the pump shaft on right side, Spit Section successively; Sealing is communicated with by connecting tube for the first Spit Section, the second suction casing, and pump shaft is supported by bearing body part, and all parts connects as a whole by bolton; Between described stator and impeller, be designed to single suction double sealing structure.Whole water pump is in a symmetrical arrangement centered by the Spit Section of pump, and autobalance is good, long service life, and maintenance cost is low; Between stator and impeller, single suction double sealing structure adopts, and has greatly increased the sealability of pump, 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.
Description
One, technical field
The utility model relates to a kind of water pump, especially a kind of self balancing energy-saving multi-stage centrifugal pump.
Two, background technique
Current, the multistage centrifugal pump of application, is all single-suction centrifugal pump, only has a suction port.The equidirectional mode of arranging in turn of all impellers of this kind of multistage centrifugal pump is arranged on a pump shaft, pump in use can produce larger axial force, for balancing axial thrust, conventionally adopt 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 Equilibrator wearing and tearing also can cause other rotor component wearing and tearing, thereby affects normal service life and the working efficiency of pump, and often changing wear-out part has also increased user's device maintenance expense.In addition, between its impeller of various centrifugal pumps of application and stator, also there is no seal arrangement now, reasons in structure makes the poor sealing performance of pump, and 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 a kind of good seal performance, the self balancing energy-saving multi-stage centrifugal pump of long service life.
The technological scheme that realizes the purpose of this utility model employing is: this pump is mainly made up of suction casing, impeller, stator, stage casing, the first Spit Section, connecting tube, Spit Section, the second suction casing, bearing body part and pump shaft; The first Spit Section, Spit Section are arranged on the middle part of pump shaft, on the pump shaft in the first left side, Spit Section, stator, impeller, stage casing, suction casing are installed from right to left successively; Stator, impeller, stage casing, the second suction casing are from left to right installed on the pump shaft on right side, Spit Section successively; Sealing is communicated with by connecting tube for the first Spit Section, the second suction casing, and pump shaft is supported by bearing body part, and all parts connects as a whole by bolton; Between described stator and impeller, be designed to single suction double sealing structure.
The beneficial effects of the utility model are: because whole water pump is in a symmetrical arrangement centered by the Spit Section of pump, thereby realize the autobalance of axial force, having avoided existing multistage centrifugal pump is to realize damage of components and the wearing and tearing that balancing axial thrust produces in operation process, extend the working life of pump, reduced customer equipment maintenance cost; Adopt single suction double sealing structure owing to adopting between stator and impeller, 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, good seal performance, and long service life, efficiency is high, and running state is very steadily reliable.
Four, brief description of the drawings
Fig. 1 is the sectional structure chart of the utility model self balancing energy-saving multi-stage centrifugal pump.
Fig. 2 is the A place enlarged view of the utility model self balancing energy-saving multi-stage centrifugal pump Fig. 1.
Five, embodiment
In the accompanying drawings, the utility model self balancing energy-saving multi-stage centrifugal pump is mainly made up of suction casing, impeller, stator, stage casing, the first Spit Section, connecting tube, Spit Section, the second suction casing, bearing body part and pump shaft; The first Spit Section 5, Spit Section 7 are arranged on the middle part of pump shaft 9, on the pump shaft 9 in 5 left sides, the first Spit Section, stator 3, impeller 2, stage casing 4, suction casing 1 are installed from right to left successively; Stator 3, impeller 2, stage casing 4, the second suction casing 8 are from left to right installed on the pump shaft 9 on 7 right sides, Spit Section successively; 6 sealings are communicated with by connecting tube for the first Spit Section 5, the second suction casing 8, and pump shaft 9 is supported by bearing body part, and all parts connects as a whole by bolton.Because whole water pump is in a symmetrical arrangement centered by the Spit Section of pump, thereby realize the autobalance of axial force, having avoided existing multistage centrifugal pump is to realize damage of components and the wearing and tearing that balancing axial thrust produces in operation process, extend the working life of pump, reduced customer equipment maintenance cost; Between described stator 3 and impeller 2, be designed to single suction double sealing structure, this single suction double sealing structure, has increased the sealability of pump greatly, reduce liquid leakage, reduced volumetric loss, improved the volumetric efficiency of pump, the self balancing effect that has increased pump, has improved pump efficiency.In a word, this multistage centrifugal pump component is few, simple in structure, and cost is low, good seal performance, and long service life, efficiency is high, and running state is very steadily reliable.
