The dismantling device of the axial flow pump has the advantages of saving time and labor, being simple in operation, and ensuring quality of the maintained axial flow pump.
Description
Technical field
The utility model relates to a kind of axial-flow pump maintenance equipment, particularly a kind of axial-flow pump dismounting device.
Background technique
Axial-flow pump is the pump that liquid is carried by the active force that the blade that rotates produces liquid along axial direction, many easily damaged partss in its pump housing have aging and a wear and tear process to axial-flow pump through long running with after using, and therefore need to do regular or irregular disintegration and change and repair.But because the volume of large-scale or superhuge axial-flow pump is large and Heavy Weight, the deadweight of some pump just has 11.5 tons, about 11 meters of self length, and it is very difficult to carry out Disintegration overhaul for so large water pump.
Fig. 1 is the schematic representation of axial-flow pump, and as shown in the figure, axial-flow pump comprises Discharging bent-tube 100 and the pump housing 200, and Discharging bent-tube 100 parts can be described as again pump seat.The bottom 101 of Discharging bent-tube 100 is fixedly connected with the pump housing 200, and the pump housing 200 itself has the multistage pipe to consist of, so the pump housing 200 is provided with adpting flange 201, is used for the connection between the multistage pipe of the pump housing own.When Discharging bent-tube 100 and the pump housing 200 being disintegrated dismounting, because the own wt of Discharging bent-tube 100 will surpass 1 ton, therefore under the simultaneously effect of making a concerted effort of self gravitation and these two bursts of power of assembly pretightening power, be difficult to Discharging bent-tube 100 is taken apart.And axial-flow pump is through after the long-term running, the fouling between the fitting surface, gets rusty and the distortion of trace etc. also can cause the tight power of each junction plane to increase.So can only employ the support force of jack it is finished separation, and use jack to be faced with the problem of two aspects, on the one hand the diameter of jack bottom is larger, and with the pump housing 200 on the monolateral distance of adpting flange 201 not enough with place jack, so jack is difficult to put surely.On the other hand, the external diameter of each section adpting flange 201 on the pump housing 200 equates therefore to be difficult to implement dismantlement work substantially.
The existing large crane that usually adopts hangs out the pump hole with axial-flow pump, then is transported to specific place, and axial-flow pump is held on horizontal position, uses sledge hammer and the bottom of Discharging bent-tube is knocked takes apart.But adopt this method need to employ the cooperation of large-scale large crane, and need larger place and haulage vehicle.Cause the activity duration of each dismounting long, operating expenses is high, and knocks the easy life-span to axial-flow pump and exert an influence.
The model utility content
For addressing the above problem, the utility model provides a kind of axial-flow pump dismounting device, quickly and easily axial-flow pump is dismantled.
For achieving the above object, axial-flow pump dismounting device of the present utility model, comprise a pair of arc plate, strut and a pair of jack, described a pair of arc plate is symmetricly set on the both sides of axial-flow pump body, described arc plate is bolted on the adpting flange at pump housing middle part, described strut is positioned at the below of described arc plate, described strut one end and described arc plate are welded and fixed, the other end is provided with adjusting screw and abuts against on the pump housing, and described a pair of jack is separately positioned on the described a pair of arc plate.
Be provided with extension bar between described jack and the described arc plate.
Adopt axial-flow pump dismounting device of the present utility model, cooperate on-the-spot electric wire hoist, can on original place pump hole, dismantle axial-flow pump, in the process of whole dismounting, can accomplish to finish apportioned effort not making in the situation about hitting with a hammer, can not cause being damaged or being out of shape because of knocking of hammer.Adopt axial-flow pump dismounting device of the present utility model, time saving and energy saving, simple to operate, guaranteed the quality of axial-flow pump after the maintenance.

Embodiment
Axial-flow pump comprises interconnective Discharging bent-tube 100 and the pump housing 200, the pump housing 200 middle parts are provided with adpting flange 201, shown in Fig. 2～4, axial-flow pump dismounting device of the present utility model comprises a pair of arc plate 10, strut 11 and a pair of jack 20, described a pair of arc plate 10 is symmetricly set on the both sides of axial-flow pump body 200, described arc plate 10 is bolted on the adpting flange 201 at the pump housing 200 middle parts, described strut 11 1 ends and described arc plate 10 are welded and fixed, the other end is provided with adjusting screw 12 and abuts against on the pump housing 200, and described a pair of jack 20 is separately positioned on the described a pair of arc plate 10.The bottom 101 of described Discharging bent-tube 100 is close at the top of described jack 20.
Axial-flow pump dismounting device of the present utility model adopts a pair of jack 20 to come Discharging bent-tube 100 is dismantled, and provides base to support by 10 pairs of jack 20 of a pair of arc plate.Bolt hole on the adpting flange 201 of the bolt hole of offering on the arc plate 10 and the pump housing 200 is corresponding, when arc plate 10 is installed, can dismantles first the bolt on several adpting flanges 201, and arc plate 10 is fixed on the adpting flange 201.Each arc plate 10 bottom strut 11 can be one or more, be used for arc plate 10 is supported, form the structure of three-support.By regulating described adjusting screw 12, the underpart of strut 11 is pressed close to by adjusting screw 12 and the pump housing 200, play a supporting role.
Jacking by jack 20 just can separate Discharging bent-tube 100 easily with the pump housing 200.
For the length of avoiding jack 20 is inadequate, between described jack 20 and the described arc plate 10 extension bar 21 is set, extension bar 21 can be selected different length as required.
Described a pair of arc plate 10 also can adopt the annular slab of split type structure.
The arc plate 10 of axial-flow pump dismounting device of the present utility model and strut 11, for jack 20 provides a base for supporting, therefore, axial-flow pump dismounting device of the present utility model can also be used for inner other the dismounting of parts of axial-flow pump, such as the box coupling in the pump housing, impeller etc.Certainly, at the top of jack be disassembled the stressed plate that an annular need be set between the object, by stressed plate power is transferred to and be disassembled on the object.
