Abstract

The utility model relates to a pipe cycling pump and in particular to a shielding magnetic force transmission pipe cycling pump which belongs to the force liquid cycling device applying domain. The cycling pump consists of a motor, a magnetic force transmission rotor, an impeller, a pump axis, a water clapboard, a pump body and so on. One end of the pump axis is fixed on the motor shell and the other end is fixed on the pump body; the fixed pump axis in the two sides can enhance the stability of the impeller rotating and reduce the swing of the impeller. The pump body is provided with a water clapboard; the water clapboard and the pump axis are provided with a liquid hole with a same center and the liquid enter the pump though the liquid inlet; the impeller can produce subpressure when the impeller rotates though the driving of the motor to make the liquid enter the impeller room though the water clapboard in the power side. Therefore, the utility model can improve the abrasion between the axis and lengthen the service life of the cycling pump as the force changing of the pump axis.

Description

A kind of pipe circle pump
Technical field the utility model relates to a kind of shielded magnetic transmission pipe circle pump, belongs to the application of forcing liquid circulating apparatus.
The use of background technique pipe circle pump in daily life and industrial and agricultural production is very general.In order to improve multiple purposes such as running efficiency of system and energy saving, often need to force liquid in pipe-line system, to circulate, this just be unable to do without pipe circle pump.Because the pump housing of recycle pump is partly worked in liquid and be to run without interruption for a long time, thus will improve recycle pump reliability of operation, reduce recycle pump operation and maintenance cost with, increase the service life.In the design of recycle pump, put forth effort to solve fluid leakage problems often, to the shielding problem of motor side, the wear problem of Sealing etc.And recycle pump is simple in structure, reduces processing, the assembly precision of each parts, improves the wear condition of each several part, can influence the working life and the maintenance condition of recycle pump equally.Now the recycle pump ubiquity that uses secondary part and impeller axially and the heavy wear problem radially, wearing and tearing can cause that problems such as scratch take place for the locating bias of parts, the part of relative movement, thereby the use that influences pump finally causes damaging, so the wearing and tearing between improvement and the minimizing relative movement part are the research topics in recycle pump design and the application always.
The summary of the invention the purpose of this utility model is to simplify pump body structure, reduce processing and the complexity and the precision of assembling, be easy to assembling, improve of the wearing and tearing of axial stressing conditions from structure, thereby reduce the operation troubles of recycle pump and be easy to operation maintenance with the parts of minimizing relative movement.
In order to achieve the above object, the related recycle pump of the utility model comprises motor part, magnetic drives rotor, impeller, pump shaft, watershed partition, pump housing few component parts.One end of pump shaft is fixed on the shell of motor part, and the other end is fixed on the pump housing, and the impeller set that is fixed together with the magnetic drives rotor is contained on the pump shaft, like this axle of impeller both pump shaft be exactly that both-end is fixed.Adorning a watershed partition in the pump housing separates intake chamber and blade wheel chamber, on watershed partition, have a liquid flow hole with pump shaft is concentric, water intake mode is designed to liquid and diffuses in intake chamber from the water intake of pump, impeller is turned over the back at the drive backspin of rotor and produce negative pressure in blade wheel chamber, liquid enters blade wheel chamber by the liquid flow hole on the watershed partition by the power side of pump like this, by the continuous rotation of impeller liquid is sent into pipeline again.
The pipe circle pump that the utility model is related, therefore do not need bearing because pump shaft is designed to fix, so just greatly reduce the complexity and the assembly precision of processing, this is not only the reliability that has reduced manufacture cost and improved pump operating cycle and has reduced maintenance work.Because pump shaft both impeller shaft is that both-end is fixing, this with the recycle pump that generally uses in the axle of impeller have only an end stationary phase ratio, stability when having strengthened impeller operation can reduce the chance that impeller when rotation and the pump housing are swept thorax, the operation stability of raising recycle pump.Effect by watershed partition makes into the water direction in the power side of impeller, can change like this impeller shaft to be subjected to force direction, thereby reduce the wearing and tearing between each component axial of relative movement, prolong the service time of recycle pump.
The concrete structure of description of drawings model utility is provided by following embodiment and accompanying drawing thereof.
Accompanying drawing is the sectional drawing of the pipe circle pump that the utility model proposes.This pipe circle pump comprises motor 1, motor casing 2, pump shaft 3, magnetic drives rotor 4, water intake 5, liquid flow hole 6, watershed partition 7, impeller 8, blade wheel chamber 9, the pump housing 10.
Embodiment describes the working condition of the pipe circle pump that the utility model proposes in detail below in conjunction with accompanying drawing.For recycle pump provides power, drive 4 rotations of magnetic drives rotor by motor 1; Impeller 8 is fixed together with magnetic drives rotor 4, and also coaxial package is on pump shaft 3, and an end of pump shaft 3 is fixed on the electric machine casing 2, and the other end is fixed on the pump housing 10; One watershed partition 7 is housed in the pump chamber, on watershed partition 7 with the coaxial liquid flow hole 6 that has of pump shaft, liquid diffuses in intake chamber the pump chamber from water intake 5, impeller 8 is turned over the back at the drive backspin of magnetic drives rotor 4 and form negative pressure in blade wheel chamber 9, liquid in the intake chamber will enter blade wheel chamber 9 from the liquid flow hole on the watershed partition 76 like this, and send the pump housing 10 and enter pipeline by the impeller 8 of rotation, in the effect that constantly promotes to realize forcing liquid circulation in the pipeline like this.
