Description
Technical field
The present invention relates to a kind of water pump, particularly a kind of disjunctor centrifugal water pump in parallel.
Background technique
The multistage single suction segmented centrifugal pump that generally uses (claiming D type pump) is because end thrust is big now, by Balance disc method balancing axial thrust, and during starting of pump station because the generation of equilibrant exists and relates to the back phenomenon, sassafras can take place to clash in short-term and grind, wearing and tearing can work the mischief after overflowing.
Summary of the invention
The object of the present invention is to provide a kind of end thrust that do not have basically, do not establish efficient, energy-conservation, few fault of Equilibrator, long-lived disjunctor series centrifugal pump in parallel.
The objective of the invention is to be achieved through the following technical solutions: it comprises pump case, the pump support, be sleeved on the pump shaft 8 that joins with power plant on the pump bearing support and be sleeved on the bearing that matches with the pump support on the pump shaft, it is characterized in that: be provided with the left water exit end 9 of water outlet interface and right water exit end 10 and be respectively equipped with water chamber around pump shaft, left side water exit end 9 connects firmly with the pump left socle, right water exit end 10 connects firmly with the pump right support, the outside of left side water exit end 9 and right water exit end 10 is respectively equipped with the pump shaft mounting hole, the outside of a left side water exit end 9 and right water exit end 10 becomes the motive sealing cooperation by the pump shaft mounting hole with pump shaft cover on being sleeved on pump shaft 8, be respectively installed with lobus sinister wheel 4 and lobus dexter wheel 5 on the pump shaft in the water chamber of left side water exit end 9 and right water exit end 10, the helix angle of lobus sinister wheel 4 and lobus dexter wheel 5 is reverse, between left water exit end 9 and right water exit end 10, become secure fit to be set with the inlet segment 1 that joins with water intake, be provided with water-inlet cavity around pump shaft in the inlet segment 1, be set with the pump shaft cover on the pump shaft.Or between left water exit end 9 and right water exit end 10 and inlet segment 1, be respectively installed with left stage casing 2 and right stage casing 3, and being provided with the chamber, stage casing around pump shaft in left stage casing 2 and the right stage casing 3, the pump shaft 8 in the chamber, stage casing is respectively installed with lobus sinister wheel 4 and lobus dexter wheel 5.Be respectively installed with left stage casing 2 and right stage casing 3 between left side water exit end 9 and right water exit end 10 and the inlet segment 1, be provided with the chamber, stage casing around pump shaft in stage casing 2, a left side and the right stage casing 3, be respectively installed with individual in the chamber, stage casing or the wheel 4 of the lobus sinister more than 2 and lobus dexter wheel 5 and left stator 6 and right stator 7.Or between left water exit end 9 and right water exit end 10 and inlet segment 1, be respectively installed with left stage casing 2 and right stage casing 3 more than 1 or 1, and being provided with the chamber, stage casing around pump shaft in left stage casing 2 and the right stage casing 3, the pump shaft 8 the chamber, stage casing in is respectively installed with lobus sinister wheel 4 and lobus dexter takes turns 5.Left side water exit end 9 and right water exit end 10 tap into the mouth of a river, lobus sinister wheel 4 that oppositely is set with respectively on the pump shaft in the chamber, stage casing in the water chamber of left water exit end 9 and right water exit end 10 or left stage casing 2 and the right stage casing 3 and lobus dexter wheel 5, and inlet segment 1 joins with water outlet.The two ends of non-equilibrium connecting tube 11 are communicated with the chamber, stage casing in left and right stage casing respectively, and non-equilibrium display list 12 was housed on non-equilibrium connecting tube 11.
From the above, the present invention is that a class does not have basically that the single suction of end thrust is two to go out doublet series Centrifugal water pump, he solves traditional multistage single suction segmented series centrifugal pump to cause technical problems such as efficient is low, fragile greatly because of end thrust, and it mainly comprises each left stage casing 2 and right stage casing 3, lobus sinister wheel 4 and lobus dexter wheel 5, left stator 6 and right stator 7, pump shaft 8, left water exit end 9 and right water exit end 10, non-equilibrium connecting tube 11, non-equilibrium display list 12 and other parts of inlet segment 1, both sides symmetry.It is that a class does not establish that Equilibrator, efficient, energy-conservation, big flow, structure knot are simple and easy to assemble, the Centrifugal water pump of long service life.Because it has cancelled Equilibrator, this operation to water pump is very useful.The one, performance improvement, efficient improve.It has eliminated the loss of equilibrium water amount; Eliminate the moving gap of string, reduced return loss in the pump; Help the long-term maintenance of impeller and stator and well align, reduce flow resistance.The 2nd, load is steady, power consumption reduces.It has eliminated the frictional resistance of Balance disc and gimbal; Eliminated the frictional resistance of high pressure water and Balance disc; Eliminated the load load (refer to magna pump with pin be connected) moving that is used to resist thrust with overcoming the coupling pin string.The 3rd, reduce amount of maintenance and expense.This series pump does not need to resemble the D type pump running check and adjusts axial string quantity and change Equilibrator accessory easy to wear; And it is easy to assembly; Gu amount of maintenance and expense significantly reduce.The 4th, reduced accident potential.Because of end thrust and string are moving is the main root of damaging water pump and breaking-up motor.And this type of pump is only required to rotate and should do not stayed unnecessary string quantity freely, has therefore eliminated the accident potential that axially grind away water pump and thrust loading are damaged motor, helps the safe operation of equipment, but and life-saving.When being used for mine drainage, be of great benefit to reducing floods hidden danger.Especially be convenient to flood well and beat " chasing after water ".
