The utility model has the advantages of simple structure, convenient, safe and reliable use, further the utility model is time and effort saving, thereby the work efficiency is improved, the deformation or fracture of the blade wheel is avoided, and the blade wheel is protected from being damaged, the dissembling difficulty is lowered, the economic profit is increased.
Description
Technical field
The utility model relates to the extracting tool of impeller, more particularly, relates to a kind of instrument that is used to dismantle impeller, and this instrument can disassemble impeller fast from centrifugal pump.
Background technology
All kinds of centrifugal pumps need to carry out regular routine maintenance behind the work certain hour, whether the water dumping hole of checking impeller is stopped up, is cleaned volute, checks mechanical seal and pump shaft, when perhaps breaking down, rapidly removing faults all needs to dismantle impeller, the general at present small, dedicated extracting tool (be commonly called as and draw horse) that uses draws horse or two pin to draw horse to dismantle as triangle.At first, remove the centrifugal pump end cap, and the locking nut of impeller is installed then and is drawn horse, is the center again with the pump shaft, impeller water dumping hole is a stress point, rotation is drawn the push rod of horse and is pulled out impeller.Because the impeller of centrifugal pump adopts the copper alloy material of good corrosion resistance basically, intensity is relatively poor, for example, be used for the centrifugal of tugboat because the operation that rides the sea for a long time, seawater corrosion is serious, includes a large amount of silt in the seawater simultaneously, therefore has bigger difficulty in the impeller operation of dismounting pump, sometimes for its centrifugal pump is overhauled maintenance, only dismantle impeller just with three to four hours.In addition, draw high in the process, cause the distortion of impeller through regular meeting in the rotation of drawing horse; if under the situation of impeller assembling tension, pump shaft distortion or impeller seriously corroded; the dismounting impeller also is easy to generate the crack, has increased dismounting impeller difficulty, has reduced operating efficiency and has caused economic loss.
Impeller was easy to generate distortion, impeller and is easy to generate the crack, increases and dismantle the impeller difficulty, efficient is low and causes the shortcoming of economic loss when therefore, the instrument that needs a kind of new being used to dismantle impeller overcame dismounting.
The utility model content
At the above-mentioned shortcoming that exists in the prior art, the purpose of this utility model provides a kind of instrument that is used to dismantle impeller, and this tool construction is simple, and is easy to use, can fast impeller be disassembled from centrifugal pump.
For achieving the above object, the utility model adopts following technical scheme:
A kind of instrument that is used to dismantle impeller, this instrument comprises mainboard, push rod, pull bar and hydraulic cylinder, the main plate center position offers jogger hole and tie rod hole, be provided with push rod in the jogger hole, push rod both sides and be positioned at mainboard and be provided with pull bar, pull bar passes mainboard and fixes with mainboard, and push rod one end is provided with hydraulic cylinder.
Described push rod one end is tapered, and an end is connected with hydraulic cylinder.
Described pull bar two ends are respectively equipped with screw thread, are provided with nut with the threaded one end of the hydraulic cylinder homonymy of described push rod.
Described pull bar is two of symmetry.
Described pull bar and described push rod are parallel to each other.
In technique scheme, the instrument that is used to dismantle impeller of the present utility model comprises mainboard, push rod, pull bar and hydraulic cylinder, the main plate center position offers jogger hole and tie rod hole, be provided with push rod in the jogger hole, push rod both sides and be positioned at mainboard and be provided with pull bar, pull bar passes mainboard and fixes with mainboard, and push rod one end is provided with hydraulic cylinder.This tool construction is simple, and is easy to use, safe and reliable, not only time saving and energy saving, improved operating efficiency, but also avoided impeller to produce distortion or crack, and the protection impeller is not damaged, and has reduced the dismounting difficulty, has increased economic benefit.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a schematic side view of the present utility model;
Fig. 3 is a user mode schematic diagram of the present utility model.
The specific embodiment
Further specify the technical solution of the utility model below in conjunction with drawings and Examples.
See also shown in Figure 1ly, the instrument 1 that is used to dismantle impeller of the present utility model comprises mainboard 2, push rod 3, pull bar 4 and hydraulic cylinder 5, and mainboard 2 centers are provided with push rod 3, and both sides are provided with pull bar 4; Push rod 3 one ends are provided with hydraulic cylinder 5.Please again in conjunction with shown in Figure 2, mainboard 2 centers are provided with jogger hole 6, and both sides are provided with the tie rod hole 7 of symmetry, and push rod 3 passes jogger hole 6, can make move left and right, and pull bar 4 passes tie rod hole 7.Please consult shown in Figure 1ly again, push rod 3 one ends are tapered, and an end is connected with hydraulic cylinder 5, and hydraulic cylinder 5 can promote push rod 3 and move right.Pull bar 4 is two of symmetry, and each pull bar 4 two ends is respectively equipped with screw thread 8, and with the hydraulic cylinder 5 of push rod 3 mutually the threaded one end 8 of the same side be provided with nut 9, nut 9 is fixed an end of pull bar 4 and mainboard 2.Pull bar 4 is parallel to each other with push rod 3.
During use, see also shown in Figure 3, pull down the end cap of centrifugal pump 10 earlier, unclamp then impeller 11 locking nut locking plate and pull down the locking nut (not shown), two pull bars, 4 right-hand members of this instrument 1 screw in respectively in the balance pipe 12 of impeller 11 then, have attacked respective threads in the balance pipe 12 in advance, and two pull bars 4 are fixedlyed connected with impeller 11, perhaps pass balance pipe 12 and use nut, and make mainboard 2 and impeller 11 keeping parallelisms in impeller 11 back locking and fixing.The tapered end of push rod 3 is aimed at the center of pump shaft 13, promoting push rods 3 by hydraulic cylinder 5 then moves right and heads in the pump shaft 13, mainboard 2 is under the action of hydraulic force of hydraulic cylinder 5 simultaneously, do to move in the other direction relative to push rod 3, because pull bar 4 is fixing with mainboard 2 by nut 9, and pull bar 4 also is moved to the left with mainboard 2, pull bar 4 impeller 11 simultaneously breaks away from pump shaft 13, slowly pull out centrifugal pump 10 at last, dismounting is finished.
The tool construction that is used to dismantle impeller of the present utility model is simple, easy to use.Centrifugal pump of dismounting needed two people to operate time half a day in the past, also needed to maintain in advance or utilize overhaul off time; The present dismounting only needs a people just can finish in one hour, shortened maintenance and service time greatly, improved operating efficiency, and avoided impeller generation when dismounting to be out of shape and to damage, and uses hydraulic cylinder time saving and energy saving, safe and reliable simultaneously, increased economic benefit.
