A rotor of the motor is coaxial with the pump body; a water inlet of the water inlet section of the pump body is an axial-direction suction inlet; and a water outlet of the water outlet section is a radial-direction exhaust port; the shell body, the guide blade and the cover board of the guide impeller are made of stainless steel plate through once-in-all stamping and welding; and the front cover board, the leaf blade and the rear cover board of the impeller are made of the stainless steel plate through once-in-all stamping and welding and are formed into a whole structure. The invention has the advantages of compact structure, strong integrality, high efficiency, stable performance, convenient processing and manufacturing, good proper alignment between the pump and the motor, small abrasion, low operating noise, convenient maintenance and low cost.
Description
Technical field:
The invention belongs to the mechanical electric apparatus equipment of a kind of liquid conveying, supercharging, particularly a kind of horizontal multistage stainless steel centrifugal pump.
Background technique:
Present multistage horizontal centrifugal pump mainly is made up of motor, the pump housing, pump shaft, blower inlet casing and impeller.The motor high speed rotating drives the impeller of pump with the speed rotation by coupling, thereby after liquid is inhaled into first order impeller, makes liquid be imported into the next stage impeller eye by blower inlet casing, and the rest may be inferred, and such liquid energy constantly increases, and obtains more high-lift.The part major part casting of the centrifugal pump of this structure forms, the flow passage components casting is more coarse, therefore reduced the efficient of pump, and, the pump structure of this structure is loose, total volume is big, weight is big, the coaxality of motor and pump is poor, operation back noise is big, performance parameter is unstable, fitting operation is inconvenient, and involves great expense.
In addition, guide vane in its blower inlet casing of stainless steel centrifugal pump of punching stretch welding at present and the blade in the impeller are for being stamped to form separately, and it is to weld separately with forward and backward cover plate, thus the crack appears easily in the welding, thus the efficient of pump is reduced.More than all deficiencies, solved effectively for a long time always.
Summary of the invention:
Purpose of the present invention just is to provide a kind of horizontal stainless steel centrifugal pump, and the floor space of this centrifugal pump is little, rational in infrastructure, compact, and good manufacturability, stable performance, efficient height are convenient to make.
Technological scheme of the present invention is: a kind of horizontal multistage stainless steel centrifugal pump, to form by motor with the pump housing, and the pump housing is made up of inlet segment, water exit end, multistage guide vane wheel and the impeller that is installed in the guide vane wheel; Guide vane wheel is made up of housing, guide vane and cover plate, and impeller is made up of front shroud, blade and back shroud; It is characterized in that: the rotor and the pump housing are coaxial, the water intake of pump housing inlet segment is axial suction port, the water outlet of water exit end is exhaust port radially, the housing of guide vane wheel, guide vane and cover plate are that a punching press of corrosion resistant plate is welded, and the front shroud of impeller, blade and back shroud are that a punching press of corrosion resistant plate is welded and is structure as a whole.
In order to control the axial position of impeller, the stainless steel interstage sleeve is housed between above-mentioned impeller and impeller shaft; In order to seal high pressure water, between pump shaft and water exit end, adopt mechanical seal.
Connect by stretching screw between the inlet segment of said pump and the water exit end.
In order to reach the sealing of pump stator, " o " shape seal ring is housed between above-mentioned each grade blower inlet casing.
Advantage of the present invention is: compact structure, integrity is strong, efficient height, the stable performance of pump, be convenient to manufacturing, pump and motor coaxality good, wearing and tearing are little, operation is got up noise is low, easy to maintenance and cost is low.

Embodiment:
A kind of horizontal multistage stainless steel centrifugal pump is made up of base 9, motor 8 and the pump housing, the motor and the pump housing coaxial 3.The pump housing is made up of inlet segment 1, water exit end 7, three grades of guide vane wheels 5 and the impeller 4 that is installed in the guide vane wheel; The water intake of inlet segment is axial suction port, and the water outlet of water exit end is exhaust port radially.Guide vane wheel is made up of housing 13, six guide vane 14 and cover plates of evenly arranging 15, impeller by front shroud 16, six evenly the blade 17 and the back shroud 18 of layout are formed.The housing of guide vane wheel, guide vane and cover plate are welded with a punching press of 0.5-1.2mm corrosion resistant plate, and the front shroud of impeller, blade and back shroud are welded with a punching press of 0.5-1.0mm corrosion resistant plate and are structure as a whole.
In order to control the axial position of impeller, stainless steel interstage sleeve 10 is housed between above-mentioned impeller and impeller shaft, lock the rotor of pumps at last by the locking nut 2 of axle front end, between this nut and the axle packing ring 12 is installed.In order to seal high pressure water, spacer 6 is installed between pump shaft and water exit end.In order to reach the sealing of pump stator, " o " shape seal ring 19 is housed between above-mentioned each grade guide vane wheel.Connect by stretching screw 11 between the inlet segment of said pump and the water exit end.
Working principle of the present invention is: this centrifugal pump has mainly adopted the straight connection type structure, and rotor is coaxial with pump, and the impeller that drives pump is with the speed rotation.Make liquid flow into impeller in the first order blower inlet casing from the axial suction port of pump, by centrifugal force liquid is thrown away, make liquid be imported into the next stage impeller eye by blower inlet casing, the rest may be inferred, and such liquid energy constantly increases, obtain more high-liftly under certain flow, final liquid is radially discharged by water exit end.
