Description
Technical field
The utility model relates to metallurgical machinery service technique field, particularly relates to centrifugal multistage pump multiple centrifugal pump impeller demolition specific purpose tool.
Background technology
At present, the extracting tool applied in industrial production is a lot, the method for dismounting that centrifugal multistage pump multiple centrifugal pump impeller demolition is prized with crowbar after generally using heating, there are the problems such as potential safety hazard overhaul efficiency is low, the problem such as impeller distortion, the increase of dynamic balancing vibration values easily causing impeller to cause because of discontinuity.In wine steel stainless steel hot-rolling operation high-pressure water descaling pump maintenance process just there is this problem in impeller demolition, high-pressure water descaling pump has ten one stage impeller, and (impeller and axle are interference fit, the magnitude of interference is 0.02-0.04mm), specific purpose tool is not had during impeller demolition operation, damage to prevent impeller, we adopt the method in pressure descaling pump stage casing, two 5t synchronous press tops to dismantle impeller, because each impulse stroke of the synchronous press of 5t only has 10mm, and the length of fit of impeller and axle has 180mm, disposable rapidly impeller top pressure can not be taken apart after impeller being heated at every turn, cause repeatedly carrying out cushioning, heating, row dismounting is compressed on top, every one-level impeller demolition needs the 2h time, 11 grades of complete of impeller demolitions need 2 day time less, so just cause the increase of maintenance task amount, operating efficiency is very low, as can be seen here, lack safety, efficient impeller demolition specific purpose tool is the basic reason causing inefficiency.
Utility model content
The purpose of this utility model is to provide a kind of specific purpose tool that rapidly and efficiently centrifugal pump impeller can be carried out dismantling, and dismantles difficult technical problem to solve centrifugal multistage pump multiple centrifugal pump impeller demolition without specific purpose tool.
Production practices and a large amount of practical technique achievements prove, making the Special-purpose hanger fixture utilizing some special, is the parts dismounting the most effective approach little to device location small space.The utility model devises special fixture according to the blade wheel structure of centrifugal pump and impeller diameter, impeller can be gripped, hubbing or top platen press is selected to carry out the dismounting of impeller, the technical problem cannot extracted fast after this addresses the problem impeller heating according to blade wheel structure feature.
For a kind of centrifugal pump impeller tool special for dismounting of hubbing scheme, it comprises clamping plate, suspension ring, is provided with snap fit bottom described clamping plate, and clamping plate movable upper end is connected with suspension ring.
For a kind of centrifugal pump impeller tool special for dismounting of top platen press scheme, it comprises clamping plate, top silk pressing thick stick, connects leading screw, location-plate, is provided with snap fit bottom described clamping plate, and clamping plate are connected with location-plate by connecting leading screw, and the middle part of location-plate is provided with top silk pressing thick stick.
The utility model has the following advantages compared with original technology:
1., because the utility model technology efficiency in unloading process is higher, operating personnel is reduced, reduces labour intensity.
2. structure is simple, with low cost, easy to make, can complete the quick-detachment of impeller of vane pump.
3. particularly relate to centrifugal multistage pump multiple centrifugal pump impeller demolition, and the specific purpose tool in the field-strip operation of various impeller of vane pump.
Accompanying drawing explanation
fig. 1 is a kind of operating diagram of centrifugal pump impeller tool special for dismounting of embodiment;
Fig. 2 is the structural representation of the centrifugal pump impeller tool special for dismounting of another kind of embodiment.
In figure: the silk pressing thick stick of 1-top, 2-connect leading screw, 3-location-plate, 4-clamping plate, 41-snap fit, 5-suspension ring, 6-impeller, 61-guide groove.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Embodiment shown in Fig. 1 is applicable to the dismounting vertically can placing the multistage centrifugal impeller of pump carrying out dismantling, and it comprises clamping plate 4, suspension ring 5, is provided with snap fit 41 bottom clamping plate 4, and clamping plate 4 movable upper end is connected with suspension ring 5.Unloading process is: the guide groove 61 snap fit (41) on clamping plate 4 being put into impeller 6, and suspension ring 5 are screwed, itself and impeller surface gapless are rocked, apply certain external force (as jack drawing) to again suspension ring 5, knock by red copper bar symmetry after impeller homogeneous heating, so just rapidly impeller drawing can be taken apart with jack.
Embodiment shown in Fig. 2 is applicable to the dismounting of single-stage blade pump impeller, it comprises clamping plate 4, top silk pressing thick stick 1, connects leading screw 2, location-plate 3, be provided with snap fit 41 bottom clamping plate 4, clamping plate 4 are connected with location-plate 3 by connecting leading screw 2, and the middle part of location-plate 3 is provided with top silk pressing thick stick 1.Operating process is for put into impeller guide groove by clamping plate 4, and connection leading screw 2 is screwed and rocks with impeller surface gapless, being nested with together with top silk pressing thick stick 1 by location-plate 3 connects on leading screw 2, and the nut connected on leading screw 2 is threaded to the position of needs, with top silk pressing thick stick 1, top pressure dismounting is carried out to the impeller after heating, so just with top silk pressing thick stick 1, impeller can be pushed up rapidly pressure and take apart.
