Description
Technical field
The utility model relates to a kind of one step single sucking clean waterpump.
Background technique
Horizontal single-stage single-suction clear-water pump, for industrial or agricultural and city, draining, fire fighting supply, metallurgical, chemical industry, weaving, the boiler hot-water pressurization cycle conveying such as papermaking and hotel and urban heating system, serviceability temperature T≤120 DEG C, clear water and physicochemical properties similar water not solids-laden fluid is sent for suction, the conveying liquid of existing clean waterpump is equal to or less than the pressure at pump intake place and components vaporize due to saturation vapour pressure under delivery temperature, pump is caused to produce noise and vibration, time serious, the flow of pump, the remarkable decline of pressure head and efficiency, also there is suction journey low simultaneously, easy generation vapour lock, ducted actual flow differs more formation oil and gas multiphase flow with rated flow, the oil transportation time is easily caused to extend at double, electric energy is wasted at double, and lubrication effect is poor, damage is large, needs often maintenance and changes, raising the cost.
Model utility content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, provides one to operate steadily, and Maintenance and Repair are convenient, and emission performance is strong, and good seal performance is lightweight, the one step single sucking clean waterpump that vapour corrosivity is good.
The utility model solves the technological scheme that its technical problem adopts: a kind of one step single sucking clean waterpump, there are pump case, pump cover and strut bearing parts, described pump case is provided with water-in flange and water-output flange, and pump case is connected with pump cover by bolt, and pump cover is connected with strut bearing parts, axle is provided with in pump case, one end of axle is provided with impeller, and axle is provided with axle sleeve, and axle is provided with axial seal ring, axial seal ring is by Gland, and packing ring and filler form.
Further, described pump case pump cover and adopt gray cast iron, malleable cast iron, nodular cast iron, carbon steel, alloyed steel, Stainless Acid Resistant Steel material make.
Further, described pump case and water-in flange and water-output flange are formed in one structure, and structure is simple, operates steadily, and Maintenance and Repair are convenient, small accommodation area.
Further, described impeller is connected by impeller nut and lock washer with axle, effectively prevents fixing impeller, prevents impeller from producing displacement and play, prevents noise and vibration.
Further, described impeller be circumferentially equidistantly welded with 6 blades, the concentric angle at interval is 60 °, and the thickness of blade is 1.5-6.0mm.
The beneficial effects of the utility model are: the utility model structure is simple, operates steadily, and Maintenance and Repair are convenient, small accommodation area, and the reliability of product is high, long service life, emission performance is strong, and good seal performance is lightweight, vapour corrosivity is good, and power consumption is low, and high lubricating effect reduces costs.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
