Abstract
The utility model relates to a direct-linkage type corrosion-resistant pump which is characterized in that a rotary shaft arranged between a motor and a pump body is fixed with a rotary body larger than the shaft diameter of the rotary shaft in the radial direction of the rotary shaft, so that the rotary shaft can be rotated conveniently for detecting an impeller and sealing and mounting states, and the rotary shaft can also be effectively fixed in radial direction for assembling and disassembling the pump conveniently. The utility model overcomes the defect that the rotary shaft of the direct-linkage type pump is rotated inconveniently for detection, assembly and disassembly.
Description
Model utility relates to a kind of straight connection type and carries the liquid medium pump, especially about the improvement to the straight connection type corrosion-resistant pump.
With motor with carry liquid medium pump direct connection, promptly machine shaft is directly as pump shaft, can effectively reduce production costs and uses floor space, and enjoy great popularity gradually.Because motor shaft and pump shaft are all one; the axial micro-play that motor shaft produces in assembling process; and the user grasps bad etc. in maintenance assembling and dissembling process intermediate gap; regular meeting causes between impeller and front pump cover and pump case grazing takes place; especially overall plastic or lining is moulded corrosion-resistant pump; also can be because of plastic impeller, lining is moulded (overall plastic) pump case, Volume Changes takes place the pump cover temperature influence, also can cause between assembling back impeller and front pump cover and pump case grazing takes place.It is dumb that pump rotating part and pump housing grazing easily cause main shaft to rotate, and serious meeting causes impeller, motor to damage.Secondly, the mechanical seal meeting of pump influences Sealing and sealability because of having tension in assembling process, crossing loose phenomenon.Therefore the straight connection type pump must carry out run-out check to axle after assembling.But because motor is connected with the pump straight connection type, motor and pump housing spacing are minimum, and axle is tiny again, thereby rotate relatively difficulty of pump shaft inspection.The dismounting of pump in maintenance process besides need radially be fixed pump shaft and not make its rotation, so that dismantle and assemble.For the straight connection type metal pump, generally can be by the other impeller of card, make pump shaft radially relative fixed do not rotate, and corrosion resistant lining is moulded or overall plastic pump, because impeller is that the working of plastics stiffness is poor, thereby can not reaches radially fixed rotating shaft and it is rotated by blocking other impeller, short tiny again rotating shaft radially fixedly brings difficulty for external force between the motor and the pump housing, therefore the mounting or dismounting of straight connection type pump are comparatively hard, and are extremely inconvenient.
The purpose of model utility is to overcome the deficiency of above-mentioned prior art, and a kind of straight connection type corrosion-resistant pump that makes things convenient for rotating shaft is provided.
Another purpose of model utility also be to provide a kind of while effectively countershaft fix, do not make its rotation, the straight connection type corrosion-resistant pump of convenient mounting or dismounting maintenance.
Model utility first purpose realizes that main the improvement is to increase by one manually to turn in the rotating shaft between the motor and the pump housing.Specifically, model utility straight connection type corrosion-resistant pump comprises coaxial direct coupled motor, corrosion-resistant pump, it is characterized in that rotating shaft radially is fixed with one than big the turning of the diameter of axle between the said motor and the pump housing.Model utility is said turns can be wheel, can also be circle or polygonal rotating disk, radially fixing then by flat key, spline or radially prop up a screw or similar approach is fixed with axle of turning.Can turn by hand rotation like this, rotating shaft is rotated, make things convenient for the inspection of assembling straight connection type pump.
Another purpose of model utility realizes, it is characterized in that on turntable surface and/or peripheral hole and/or pit and/or the protrusion that is used for radial location that be processed with.By being inserted, the card of hole on the rotating disk or groove or protrusion reaches radially that fixed rotating shaft does not make its rotation, the easy assembly and disassembly pump housing.Hole or groove on the said rotating disk can be the some axial bores of processing on card, also can be at dish side face processing radial hole or pit.Then can directly reach radially fixing for runner, thereby omit reprocessing groove or hole by the spoke bar.
The said corrosion-resistant pump of the utility model specially refers to the pump that plastic lined pump, overall plastic pump and plastic impeller are formed, and can be various self-priming pumps and centrifugal pump; Said motor is connected with pump shaft is coaxial, is meant that the machine shaft lengthening is uninterruptedly directly as pump shaft.
Further specify model utility technological scheme, structure and working procedure below in conjunction with accompanying drawing, so that the model utility technological scheme is had further understanding.
Fig. 1 is a model utility basic structure schematic representation.
Fig. 2 for turn with the diameter of axle to fixing structure for amplifying schematic representation.
Fig. 3 is used for radially fixedly pit, hole, projective structure schematic representation for rotating disk.
Fig. 4 is a rotating disk side face radial aperture structural representation.
Fig. 5 is Fig. 4 sectional structure schematic representation.
Fig. 6 has the groove structure schematic representation for being with flanging (lid shape) rotating disk and periphery.
Fig. 7 is Fig. 6 sectional structure schematic representation.
Fig. 8 rotaring wheel structure schematic representation.
Referring to Fig. 1-2, the straight connection type corrosion-resistant pump is by forming with the pump housing 2 with the motor 1 of (one) axle 3 adjacent connections, on motor and pump housing countershaft by flat key 5 and/or radially prop up a screw 7 and radially be fixed with and turn 4 (being preferably circular), friction when rotating for increasing hand, the side face of turning preferably is processed with the peristome face.4 the axially locating of turning compresses the formation axial restraint by the shaft shoulder 8, corrosion resistant axle sleeve 6.Hand rotation is turned, and gets final product rotating shaft.
Referring to Fig. 3-7, can be processed with the pit 9 that is used for radial location, radial blind holes 11, protrude 13 and/or on card, be processed with axial bore 10 for the rotating disk side face of turning.Or with rotating disk make the band flanging lid shape, and its lid flanging be processed with breach 12.Radially during fixed rotating shaft, can axially be interspersed in 13 of axial bore 10, pit 9 or bumps as metal bar by strong, or insert in radial blind holes 11, the breach 12, or hole, pit, bump be fixed, can reach radially fixed rotating shaft by additive method.
Model utility is turned except that rotating disk, can also be handwheel (Fig. 8).
The model utility concrete structure is not limited to accompanying drawing, under model utility is conceived substantially, suitably departs from embodiment, still truely uses novel protected scope.Model utility since between the motor of straight connection type pump and the pump housing rotating shaft be provided with radially fixingly than big the turning of the diameter of axle, and the pit that can make rotating shaft radially fixing, protrusion, hole etc. are set on turning.Not only can conveniently rotate inspection and the adjustment that pump shaft is used for assemble pump, but but also effective diameter to fixed rotating shaft, convenient mounting or dismounting maintenance has overcome the defective of check of straight connection type pump rotating shaft and assembly and disassembly inconvenience.
