Background technology
At present, desulfuration absorbing tower circulating pump is used widely in every profession and trade, play in China's flue gas desulfurization industry to Close important effect.The medium mainly carried due to desulfuration absorbing tower is limestone-gypsum serosity, therefore wear-resisting to circulating pump Damage decay resistance require higher, and domestic desulfuration absorbing tower circulating pump due to each side such as the Hydraulic Design, structure design because of The impact of element, the most inefficient, the life-span of mechanical seal and bearing is short, the abrasion-proof corrosion-proof poor performance of material, and product cost Higher.
Utility model content
Technical problem: cause pump normally to work due to wear parts abrasion for existing desulfuration absorbing tower circulating pump Defect, this utility model provides a kind of high-efficiency desulfurization absorption tower circulating pump.
Technical scheme: a kind of high-efficiency desulfurization absorption tower circulating pump that this utility model provides, including the pump housing, rear pump cover, leaf Wheel, main shaft, back shroud, impeller clearance autocompensation installation;Described pump housing sidewall is provided with inlet, top is provided with liquid outlet, Described rear pump cover is located in inlet opposing sidewalls;Described impeller is located in the pump housing;Described main shaft passes rear pump cover and back shroud And be connected with impeller by key;The autocompensation installation of described impeller clearance includes elastomeric element and wearing plate, and be located at the pump housing and Between impeller, described elastomeric element one end is fixed on pump housing medial wall, and the other end is connected with wearing plate, wearing plate and impeller phase It is abutted against;Described back shroud is the conical structure of hollow, forms cone seal chamber between itself and rear pump cover;Described rear pump cover and pump Mechanically-sealing apparatus it is provided with between body.
As improvement, also include fluid reservoir;Described fluid reservoir is located at bottom the pump housing, is provided with between described fluid reservoir and the pump housing Cutoff board, described fluid reservoir bottom is provided with tap hole, and described tap hole is provided with screw plug.
Improving as another kind, described impeller is half-opened impeller.
Improving as another kind, described key and impeller are connected by impeller holding screw.
Beneficial effect: the desulfuration absorbing tower circulating pump simple in construction, with low cost that this utility model provides, efficiency is high, close Envelope property is good, and service life is long, it is to avoid problem scrapped by the desulfuration absorbing tower circulating pump caused due to damage of components, is substantially reduced Production and operation expense, improve the competitiveness of product in market.
Accompanying drawing explanation
Fig. 1 is desulfuration absorbing tower circulating pump structure chart of the present utility model.
Detailed description of the invention
Below this utility model desulfuration absorbing tower circulating pump is further illustrated.
High-efficiency desulfurization absorption tower circulating pump, is shown in Fig. 1, including the pump housing 1, rear pump cover 2, impeller 3, main shaft 4, back shroud 5, impeller Automatic compensator for clearance, fluid reservoir 13.
The pump housing 1 sidewall is provided with inlet 11, top is provided with liquid outlet 12, and rear pump cover 2 is located at inlet 11 opposing sidewalls On;Impeller 3 is located in the pump housing 1;Main shaft 4 is passed rear pump cover 2 and back shroud 5 and is connected with impeller 3 by key 6, key 6 and impeller 3 Connected by impeller holding screw 16.
Impeller clearance autocompensation installation includes elastomeric element 7 and wearing plate 8, and is located between the pump housing 1 and impeller 3, bullet Property parts 7 one end is fixed on the pump housing 1 medial wall, and the other end is connected with wearing plate 8, and wearing plate 8 is abutted against with impeller 3 phase.The pump housing 1 And be provided with impeller clearance between impeller 3 and automatically compensate equipment, one end of elastomeric element 7 is fixed on the pump housing 1, and other end is fixed On wearing plate 8, the gap 17 between wearing plate 8 and impeller 3 is compensated automatically by elastomeric element 7, when wearing plate 8 is because of abrasion and corruption When erosion causes damaging, elastomeric element 7 promote it to move to impeller direction, automatically compensate the gap 17 that abrasion produces, it is ensured that Gap 17 is fluctuation≤0.5mm in allowed band, and the operating pressure making desulfuration absorbing tower circulating pump is stable, continues to transport in high efficient area OK.The desulfuration absorbing tower circulating pump simple in construction that this utility model provides, can when wearing plate damages and causes gap unadjustable Changing wearing plate, maintenance cost is low, it is to avoid scraps problem owing to wearing plate damages the complete machine caused, improves desulfuration absorbing tower The work efficiency of circulating pump and operational reliability.
Back shroud 5 is the conical structure of hollow, forms cone seal chamber 9 between itself and rear pump cover 2;Rear pump cover 2 and pump Mechanically-sealing apparatus 10 it is provided with between body 1.Impeller 3 is half-opened impeller.This utility model uses two ways to ensure that the pump housing Sealing: one, between rear pump cover 2 and back shroud 5 formed cone seal chamber 9, cone seal chamber 9 is designed to big pyramidal structure Form;Its two, use mechanically-sealing apparatus 10;This utility model uses both the above mode, even if using outer flushing cooling close The coolant of the mode of front cover also outside is also difficult to enter in the pump housing 1, substantially increases the reliability of sealing and making of circulating pump Use the life-span.
Fluid reservoir 13 is located at bottom the pump housing 1, is provided with cutoff board 14 between fluid reservoir 13 and the pump housing 1, and fluid reservoir 13 bottom sets Tap hole, tap hole is had to be provided with screw plug 15.
