Abstract
The utility model relates to the technical field of nonmetallic pumps, in particular to an ultrahigh molecular polyethylene erosion-resistant abrasion-resistant lining plastic pump, which is mainly composed of a front gland bush (1), a pump body (2), a rear pump cover (5), a vane wheel (3), a rear guard plate (4), a sealing component (6) and a bracket part (7), wherein, the vane wheel is supported by a bracket type hanging arm, and plastic layers are respectively lined on the metallic matrixes of the gland bush (1), the pump body (2), the vane wheel (3) and the rear guard plate (4) by mould pressing. Compared with the prior art, when the utility model is repaired, the pump body and short inlet and outlet pipes do not need to be disassembled in order to draw the vane wheel out, so the utility model is characterized by convenient maintenance, good processing technique of lining plastic, erosion resistance, abrasion resistance, high efficiency, long lifespan, etc. The utility model can be widely applied to pumps used for the fuel gas desulfurization of power plants, papermaking pumps, chemical pumps, municipal drainage projects, etc.
Description
[technical field]
The utility model relates to the nonmetal pump technical field, particularly a kind of anticorrosive anti-wear plastic lined pump of ultra high molecular polyethylene.
[background technique]
Existing plastic lined pump, be mostly on the basis of standard chemical pump, consider the processing characteristic of plastic lined pump, front and rear cover plate changes straight line into, and its shortcoming is: hydraulic efficiency is low, than the low 20-30% of standard chemical pump, because by the clean waterpump Design Theory, so when being used to carry the slip that contains solid particle, the abrasion poor performance, the life-span falls short of.
[summary of the invention]
Task of the present utility model provides a kind of improved plastic lined pump, the structure that bearing bracket, cantilever are installed, and having lining, to mould technology capability good, uses, easy to maintenance anticorrosive anti-wear, characteristics such as efficient height.
The utility model adopts following technical proposals: a kind of anticorrosive anti-wear plastic lined pump is provided, mainly form by preceding gland, the pump housing and rear pump cover 5, impeller 3, back backplate 4, black box 6 and carriage member 7, impeller adopts the bracket type cantilever support, mold pressing lining one deck plastic layer 9 on the metallic matrix of described preceding gland 1, the pump housing 2, impeller 3 and back backplate 4.
Described plastic layer 9 is modification supramolecular polyethylene plastics.Described impeller 3 studs with metalwork in plastic layer.Described back backplate 4 is provided with a conical cavity 8 that opens wide, and is beneficial to gas, solid separates with water, thereby prevents the dry friction of machine envelope.Impeller, pump housing waterpower part are pressed transh pump solid-liquid two-phase flow Design Theory, strengthen impeller outlet width.
Plastic lined pump of the present utility model, the forward and backward cantilever structure that opens the door of employing bearing bracket.If desired,, during maintenance, can not dismantle the pump housing and import and export short tube, can extract impeller out by between pump and motor lengthened coupling being installed; Hydraulic component such as the pump housing and impeller etc., the design theory design of pressing transh pump strengthens impeller outlet width, reduces the speed of fluid, thereby improves wear-corrosion resistance; The advantage of performance plastics corrosion resistant, anticorrosive anti-wear, the efficient height, the life-span is long.
The pump housing of the present utility model and pump cover etc. adopt gray iron or magnesium iron metal, the lined with ultra-high molecular polyethylene, and impeller is metal inlaying spare in plastics such as ultra high molecular polyethylene.The performance ultra high molecular polyethylene is corrosion resistant both, wear-resisting again advantage, and alternative copper and stainless steel, its price is low more than 50%, saves precious metal, alleviates whole pump weight, saves cost.
Plastic lined pump of the present utility model is widely used in generating plant flue gas desulfurization pump, papermaking pump, chemicalpump, municipal drainage project etc.
[description of drawings]
Fig. 1 is a structural representation of the present utility model;
Referring to Fig. 1,1 is that gland, 2 is that the pump housing, 3 is that impeller, 4 is that back backplate, 5 is that rear pump cover, 6 is that black box, 7 is that carriage member, 8 is that conical cavity, 9 is plastic layer.
[specific embodiment]
Below in conjunction with the drawings and specific embodiments the utility model is done detailed description:
As shown in Figure 1, the preceding gland 1 of this plastic lined pump, the pump housing 2, back backplate 4 grades are at metallic matrix mold pressing lined with ultra-high molecular polyethylene; Mold insert in impeller 3 usefulness stainless steels are done, plastics such as outer lining ultra high molecular polyethylene.The ultra high molecular polyethylene that is served as a contrast is the material modified of special formulation, has improved flowability, is convenient to mold pressing, still keeps corrosion resistant, wear-resisting advantage.
Waterpower parts such as the impeller 3 and the pump housing 2 are pressed transh pump solid-liquid two-phase flow Design Theory, strengthen exit width, and are low thereby the medium relative current hastens, big by size, anticorrosive anti-wear.
Rotor portion adopts bracket type to support.During maintenance, can unclamp turnbuckle, not dismantle the pump housing, just can extract out the back: comprise rear pump cover 5, impeller 3, back backplate 4, black box 6 and carriage member 7 etc.
Claims (4)
1. an anticorrosive anti-wear plastic lined pump comprises preceding gland (1), the pump housing (2), rear pump cover (5), impeller (3), back backplate (4), black box (6) and carriage member (7), and it is characterized in that: impeller adopts the bracket type cantilever support; Mold pressing lining one deck plastic layer (9) on the metallic matrix of gland (1), the pump housing (2), impeller (3) and back backplate (4) before described.
