Abstract
The utility model relates to a kind of novel double suction torque flow pump, it is mainly by impeller nut (1), protecgulum (2), double-entry impeller (3), the pump housing (4), secondary intake chamber (5), filler chamber (6), bearing support upper bracket (7), right bearing gland (8), wearing plate (9), Gland (10), bearing support (11), bearing support lower support frame (12) forms, the described pump housing is provided with double-entry impeller in (4), and double-entry impeller (3) is connected with bearing support (11) by main shaft, it is characterized in that: the eccentric d=8-15mm that settles of impeller of described torque flow pump.The feature that this pump has been inherited torque flow pump has the feature of double suction pump concurrently simultaneously, and axle is carried out to bias and settle, thereby stressed convergence balance while making impeller operation is moved more steady.
Description
Technical field
The utility model belongs to pump field, is mainly the inefficiency for traditional torque flow pump, rotate not steady, the problem such as not smooth of blade inner fluid.By changing the mechanism of torque flow pump inner chamber and impeller, thereby its efficiency is greatly improved.
Background technique
Double suction torque flow pump is used for pumping complex dielectrics or impurity containing fluid, as contained rubbish, the two-phase fluid of short fibre material or ight soil, but also guaranteed the efficiency of pump simultaneously, pump suction performance is good, there is good anti-cavitation performance, can pump the liquid that gas content is higher, also can pump high concentration, torque flow pump compare with other transh pump have without plugging performance good, can be by about solid particle suitable with pump discharge bore, but the material of carrying is had to certain destructiveness, it is responsive like that axial clearance between impeller and the pump housing is not so good as centrifugal pump to the impact of pump performance, without gap, adjust.Vortex pump impeller is mostly open type radial impeller, and manufacturing process is simple, and impeller channel is easily processed, but impeller in running exists equilibrium problem, and impeller operation is steady not, and traditional double suction torque flow pump needs certain optimization.
Model utility content
The purpose of this utility model is to optimize traditional torque flow pump, by the improvement to pump housing inner-cavity structure, and adopt double-entry impeller simultaneously, change the blade structure of impeller, and the balance optimizing to rotary blade, make this double suction torque flow pump obtain certain raising than traditional torque flow pump efficiency, operation more steady, overall performance improves.
The utility model is a kind of novel double suction torque flow pump, its working principle is that medium is increased by the effect energy of centrifugal force when vane rotary, entering interlobate medium moved together with impeller by the promotion of blade, near medium impeller outlet top has formed because centrifugal force is larger and has connected stream, medium at impeller middle part has formed circular flow, flow through pump chamber outlet of perforation is flowed out, and forms certain lift.Solid particle in medium and fiber obtain energy under the effect of circular flow, and the overwhelming majority is without impeller, and motion is discharged by pump discharge in without phyllocyst, thereby reach the object of carrying complex dielectrics or impurity containing fluid.The feature that this pump has been inherited torque flow pump has the feature of double suction pump concurrently simultaneously, and it adopts double-entry impeller, and it is equivalent to the single suction impeller of two same diameter and works simultaneously, in same impeller outer diameter down-off, can increase and be twice, this blade wheel structure is symmetrical, there is no axial force, and axially operation is more steady.During due to impeller operation, inner outlet place, pump housing chamber water pressure is less, thus impeller be subject to force unbalance, so the utility model carries out bias to axle and settles, thereby makes the running convergence balance of impeller.Torque flow pump is mainly used in, in the large more environment of solid particle, adopting deviated splitter vane can effectively prevent the blockage problem of solid particle in runner.
The utility model is mainly by impeller nut, protecgulum, double-entry impeller, the pump housing, secondary intake chamber, filler chamber, bearing support upper bracket, right bearing gland, wearing plate, Gland, bearing support, bearing support lower support frame forms, in the described pump housing, be provided with double-entry impeller, double-entry impeller is connected with bearing support by main shaft, and this torque flow pump adopts double-entry impeller, this impeller adopts eccentric setting, eccentric distance d=8-15mm; Described impeller consists of linear leaf and short blade, short blade length L
