Abstract
The utility model relates to an easy-to-disassemble vertical chemical pump which includes a pump body, a bracket, a blade wheel, a pump cover, a shaft, a shell clamping shaft connector, a sliding bearing, a mechanical seal and a seal pressing cover. An outer dead opening of the pump body matches with an inner dead opening of the bracket, and the pump body and the bracket is fixedly connected with each other through a coupling bolt arranged on the inner side of the bracket. An inner dead opening of the pump body is coordinately connected with an outer dead opening of the pump cover, and a coupling bolt of the pump body is positioned on the outer side of the pump cover. The coupling bolt of the pump body and the bracket are staggered with the coupling bolts of the pump body and the pump cover on the periphery. The pump cover is provided with more than three axially holding bolts, and the mechanical seal and the seal pressing cover are positioned on the upper side of the sliding bearing. The mechanical seal on the utility model can be independently disassembled or together with a rotor and the pump body so that the disassembly is more convenient, which satisfies the technical requirement in the independent disassembly of the blade wheel and the shaft. The utility model is simple and compact in structure, highly reliable in performance, low in production cost and widely applicable for the upright or horizontal chemical centrifugal pump, the upright or horizontal water clearing centrifugal pump and the upright multi-step pump.
Description
Technical field
The utility model relates to chemical pump, particularly a kind of easy-to-dismount vertical chemical pump.
Background technique
Existing easy-to-detach pump product all is under the prerequisite of not dismantling motor, and dismounting rotor or mechanical seal are concluded and got up to mainly contain following two kinds of situations:
1. can be with rotor, pump cover, mechanical seal integral demounting, but can not dismantle mechanical seal separately.
2. can dismantle mechanical seal, but can not dismantle rotor, as patent No. ZL90204048.0, have certain narrow limitation.
Especially when the chemical pump of the medium that is corrosive is carried in dismounting, because mechanical seal is different with the replacement cycle of impeller, axle, remove difficultly more, perhaps can only partly dismantle, can not reach dismounting, technical requirements easy to maintenance fully.
Summary of the invention
Of the present utility modelly just tear the technical problem that vertical chemical pump solves open and be: both can dismantle mechanical seal separately, also can the integral demounting rotor, pump cover, mechanical seal.
The technical solution of the utility model is as follows:
A kind ofly just tear vertical chemical pump open, it comprises the pump housing, support, impeller, pump cover, axle, clamping coupling, sliding bearing, mechanical seal and sealing gland, the outer stopper of the described pump housing and support inner stopper are connected, the pump housing is fixedlyed connected by the attachment bolt that is placed in the support inboard with support, the inner stopper of the pump housing and pump cover outer stopper are connected, its attachment bolt is placed in the pump cover outside, and the attachment bolt of the attachment bolt of the pump housing and support and the pump housing and pump cover staggers on circumference; Described pump cover is provided with axial jack bolt more than three; Described mechanical seal and sealing gland are placed on the upside of sliding bearing.
The utlity model has following advantage:
1. because both can the integral demounting rotor, mechanical seal be can dismantle separately again,, mechanical seal and impeller, a technical requirements of dismantling respectively satisfied so the utility model dismounting is more convenient.
2. the utility model is because simple in structure, compact, thus the functional reliability height, low cost of manufacture.
3. structure of the present utility model is widely used in vertical chemical centrifugal pump, vertical clear water centrifugal pump and horizontal chemical centrifugal pump, horizontal clear water centrifugal pump, MODEL VERTICAL MULTISTAGE PUMP.
Description of drawings
Fig. 1 is a structural representation of just tearing vertical chemical pump open of the present utility model.
Fig. 2 is the schematic representation of Fig. 1 chemical pump when dismounting sealing gland, mechanical seal.
Fig. 3 is the schematic representation of Fig. 1 chemical pump when integral demounting.
Embodiment
Referring to Fig. 1, the utility model is that a kind of one step single sucking is just torn vertical chemical centrifugal pump open, comprises the pump housing 7, support 14, impeller 6, pump cover 12, axle 1, clamping coupling 9, sliding bearing 11, mechanical seal 10 and sealing gland 2.
The outer stopper of the pump housing 7 cooperates connection with the inner stopper of support 14, and attachment bolt 13 is fixed together the support 14 and the pump housing 7 in support 14 inboards.The outer stopper of the inner stopper of the pump housing 7 and pump cover 2 is connected, and attachment bolt 5 links together the pump cover 12 and the pump housing 7 in pump cover 12 outsides.The pump housing 7 staggers on circumference with the attachment bolt 13 of support 14 and the attachment bolt 5 of the pump housing 7 and pump cover 2.The connection petal of support 14 is staggeredly arranged on circumference with the petal that connects of pump cover 12.
Three or four axial jack bolts 4 are set on pump cover 12.Pump cover 12 is designed to inside and outside two chambeies, and inner chamber is worn axle 1, and exocoel is by mechanical seal 10 high pressure washing liquid or Lubricantss.Mechanical seal 10 and sealing gland 2 are placed on the upside of sliding bearing 11.The axial length of sealing gland 2 should be less than the distance of axle 1 upper end and motor shaft end.
Pump cover 12 is provided with oblique aperture 3, and sealing gland 2 is provided with aperture 21, impeller 6 be provided with aperture 8 near the wheel hub position.Highly pressurised liquid in the pump housing 7 enters the exocoel of pump cover 12 through aperture 3, by aperture 21, forms tuftlet liquid stream flushing sealing surface, enters the gap of axle 1 and sliding bearing 11 again, and lubrication sliding bearing 11 is got back to the import of impeller 6 again by aperture 8, form circulation loop.
Referring to Fig. 2, when mechanical seal 10 damages, unload clamping coupling 9 earlier, unload sealing gland 2 again, can change mechanical seal 10 easily.
Referring to Fig. 3, when impeller 6 corrosion and damage, unload clamping coupling 9 earlier, unload attachment bolt 5 again, twist jack bolt 4, rotor and pump cover 12, mechanical seal 10 integral body are mentioned, the inlet seal face of impeller 6 and the cooperation seam and the pump housing 7 of pump cover 12 are separated from, side draw, rotation, the whole impeller 6 that takes out can be changed impeller 6 easily.
