Abstract
The utility model discloses a novel engineering plastic chemical stuff pump, which comprises a front pump cover, a pump body, an impeller, a rear pump cover, a cartridge mechanical seal, a suspension part, a shaft coupling, a motor, a support plate and a connecting plate, wherein the pump body is molded in an all-plastic die pressing way; the bottom of the support plate is fixedly connected with a bottom plate, and the side part of the support plate is fixedly connected with the pump body; the front pump cover, the pump body and the support plate are fixedly connected into a whole, and then are fixedly connected to the bottom plate; the two sides of the connecting plate are fixedly connected with the support plate and the suspension part respectively; the impeller, the rear pump cover and the connecting plate are fixedly connected with the cartridge mechanical seal and the suspension part, and then are fixedly connected with the front pump cover, the pump body and the support plate. According to the novel engineering plastic chemical stuff pump, the pump body is molded in the all-plastic die pressing way, so that production cost is saved. In field maintenance, all rotor parts of the impeller, the rear pump cover and the suspension part can be pulled out from a rear part, and an inlet pipeline and an outlet pipeline are not required to be disassembled, so that the novel engineering plastic chemical stuff pump is convenient to overhaul, and overhauling time is greatly shortened.
Description
Technical field
The utility model relates to a kind of chemical industry stock pump, relates in particular to a kind of model engineering plastic chemical industry stock pump.
Background technique
The current occasion that is used for carrying various corrosivity in industries such as chemical industry, nonferrous metallurgy, chlorine industry, desulfurization, environmental protection, mine ore dressings, has certain solid material medium; It is higher to remove temperature; Need the high metal pump of heatproof and solid content is more, particle needs select engineering plastics chemical industry stock pump (being commonly called as the UHB mortar pump) mostly for use with beyond the heavy slag stock pump more greatly, firmly.
Mortar pump belongs to the cantilever type single stage single suction volute pump; Aim to carry and contain fine grain Korrosionsmedium and develop; This pump adopts steel lining ultra-high molecular mass polyethylene (UHMWPE) to process; This material is that the pump of present latest generation is used the anticorrosive anti-wear engineering plastics, and its most outstanding advantage is that it has excellent abrasive, impact resistance (especially low-temperature impact-resistant), creep resistance (resisting environmental stress and cracking) and fabulous corrosion resistance in all plastics.Mortar pump is that a kind of ability adapts to the pump of various working condition, as carries acid, alkaline clear liquid or slip; The various corrosive ore pulp of smelting industry; All kinds of diluted acids of sulfuric acid industry; All kinds of sewage of environmental protection industry (epi) etc.But mortar pump adopts drawing frame structure, when field maintenance and replacing easily damaged parts, needs to remove and imports and exports pipeline, and is cumbersome.
The model utility content
The purpose of the utility model is to provide a kind of convenient, as to shorten repair time model engineering plastic chemical industry stock pump that keeps in repair.
For realizing above-mentioned purpose, the technological scheme that the utility model is taked is:
A kind of model engineering plastic chemical industry stock pump comprises front pump cover, the pump housing, impeller, rear pump cover, integrated mechanical sealing, sprung parts, coupling and motor, also comprises dunnage and connecting plate; The said pump housing is overall plastic compression molding, and said dunnage bottom is fixedly connected with base plate, and sidepiece is fixedly connected with the pump housing, is fixedly connected on the base plate after said front pump cover, the pump housing and dunnage are fixedly connected and are integral; The both sides of said connecting plate are fixedly connected with sprung parts with said dunnage respectively, and said impeller, rear pump cover, connecting plate and integrated mechanical sealing are fixedly connected with front pump cover, the pump housing and dunnage with after sprung parts is fixedly connected again.
Said sprung parts bottom is provided with the suspension spike, and said suspension spike is fixedly connected with base plate.
The model engineering plastic chemical industry stock pump that uses the utility model to provide, the pump housing is used overall plastic compression molding, presses the back overall shrinkage, does not have shrinking stress, need not adopt the box hat liner or add inserts to form, and has practiced thrift cost of production.During field maintenance; With motor and disconnect coupling, unclamp the connecting bolt of connecting plate and support plate from the rear portion, remove the connecting bolt of suspension spike and base plate again; Can all rotor parts of impeller, rear pump cover and suspension assembly be extracted out simultaneously; Need not take the import and export pipeline apart, maintenance is convenient, has shortened the repair time greatly.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure, 1-front pump cover, the 2-pump housing, 3-impeller, 4-dunnage, 5-rear pump cover, 6-connecting plate, 7-machine envelope connecting bolt, 8-integrated mechanical sealing, 9-sprung parts, 10-connecting bolt, 11-base plate, 12-suspension spike, 13-coupling, 14-motor.
Embodiment
Below in conjunction with specific embodiment and accompanying drawing thereof the present invention is described further.
As shown in Figure 1; The utility model provides a kind of model engineering plastic chemical industry stock pump; Comprise front pump cover 1, the pump housing 2, impeller 3, rear pump cover 5, integrated mechanical sealing 8, sprung parts 9, base plate 11, coupling 13 and motor 14, also comprise dunnage 4 and connecting plate 6.The pump housing 2 is overall plastic compression moldings.
During maintenance, throw off, unclamp the connecting bolt 10 of connecting plate 6 and support plate 4 from the rear portion with motor 14 and coupling 13; It is close to unclamp unit loading type machinery, and 8 machine seals connecting bolt 7, removes the connecting bolt of suspension spike 12 and base plate 11 again; Can impeller 3, rear pump cover 5 and all rotor parts of suspension assembly be extracted out simultaneously; Need not take the import and export pipeline apart, maintenance is convenient, has shortened the repair time greatly.
Above-described only is the preferred embodiment of the utility model, does not limit to the utility model.Should be understood that for the person of ordinary skill of the art, under the teachings that the utility model provided, can also make other equivalent modifications and improvement, all can realize the purpose of the utility model, all should be regarded as the protection domain of the utility model.
