Because impeller blade 5 and gusset 6 are thick up to 12mm, mother metal merges less, therefore there is gap at welding point, is soldered to end and receives arc effect
Really poor, because inside has air, there is weld defect, cause stress concentration in welding tail end.
During Water-ring vacuum pump operation, the water in pump is acted on by centrifugal force formed in the pump housing water ring for rotation, leaf
The side plate at piece and two ends forms closed cavity, when the cavity volume of sealing gradually expands, forms high vacuum by condenser
Interior gas suction, is gradually tapered up in sealed volume, and gas is discharged from steam vent, and impeller every revolution is just repeated once by dilatation
To the process shunk.If the water that water ring is formed in pump is less than the vaporization pressure corresponding to coolant-temperature gage in the pressure of a certain regional area
Power, water is to begin to boil off, and forms steam bubble, causes cavitation damage, water ring vacuum pump impeller of rotor piece and wheel hub, central dividing plate and muscle
Easily fracture damage at plate welding seams, drastically influence the stable operation of unit.
Utility model content：
The purpose of this utility model is that offer one kind effectively reduction water ring vacuum pump rotor rupture phenomenon, raising water ring are true
The water ring vacuum pump rotor structure of empty pump operation reliability.
The purpose of this utility model is implemented by following technical scheme, a kind of water ring vacuum pump rotor structure, and it includes rotating shaft
With the wheel hub being fixed in rotating shaft, the middle part of the wheel hub is circumferentially integrally formed with the central dividing plate of annular, the centre
Impeller blade draw-in groove is along the circumferential direction equidistantly provided with the outer of dividing plate；Its gusset for also including impeller blade and annular, it is described
Impeller blade is arcuate structure；The bottom center of the impeller blade is provided with dividing plate draw-in groove corresponding with the impeller blade draw-in groove, described
The top two ends of impeller blade offer gusset groove；The impeller blade at the top of the dividing plate draw-in groove is plugged in the impeller blade card
In groove, the central dividing plate of the impeller blade draw-in groove bottom is plugged in the dividing plate draw-in groove, the impeller blade bottom margin
With the hub welding, the impeller blade and the central dividing plate of the impeller blade draw-in groove both sides are welded；The impeller blade
Two ends are equipped with the gusset, and the gusset and gusset groove grafting each described are simultaneously welded and fixed.
Further, the gusset includes the symmetrically arranged semicircular gusset piece of two panels, gusset piece welding described in two panels.
Further, because impeller blade thickness is thicker, more than 12mm is reached, so in the impeller blade bottom margin, institute
Built-up welding is carried out after groove is opened up on the impeller blade for stating dividing plate draw-in groove and the gusset groove both sides, height >=10mm is welded.
Further, the groove angle of the groove is 60 °.
Further, the top of the impeller blade is concordant with the central dividing plate outer.
Further, the top of the gusset is concordant with the top of the impeller blade.
Advantage of the present utility model：
1st, impeller blade of the present utility model and gusset are designed using integrative-structure, and gusset, impeller blade and central dividing plate
Fixed by the way of being welded after first grafting, greatly improve the intensity of Water-ring vacuum pump rotor, improve service life.
2nd, impeller blade and wheel hub, central dividing plate and gusset are fixed and connected by the utility model by the way of built-up welding after bevel
Connect, impeller blade is fully merged with the mother metal of wheel hub, central dividing plate and gusset, reach seamless welding, weld is not easy to crack, greatly
Improve the structural strength of weld seam.
