Abstract
The utility model relates to a peripheral canned pump with corrosion resistance, large temperature range, small flow and high lift, comprising a pump body, an impeller, a housing, a motor and a heat exchanger. The pump body and the impeller are in a peripheral pump structure. The motor is a canned motor. A stator shielding sleeve is installed on the outer side of the stator winding. A rotor shielding sleeve is installed on the outer side of a casting aluminum rotor of the rotor component. The motor is connected with the pump body through a flange. When the peripheral canned pump works, cooling for the canned motor and lubricating and cooling for the bearing are finished through circulation of media, driven by an auxiliary impeller arranged on the rotor shaft between the stator and rotor chambers and the heat exchanger; media not output by the pump returns back to the motor chamber for circulating and cooling; the pump flow is small and the pump lift is high and it is unnecessary to provide a bypass pipe. The canned pump set has high efficiency and completely meets the requirement of no leakage, small flow and high lift.
Description
Technical field
The utility model relates to a kind of corrosion-resistant, large and small flow of serviceability temperature scope, high-lift vortex canned motorpump.
Background technique
At present, being used for requirement does not have and leak to carry the canned motorpump kind of liquid more, all be to be grouped into by pump and motor section, but its pump part all is to adopt centrifugal pump structure, and the minimum continuous flow of requirement is all at 1.2m
3More than/the h.If lift requires high, traffic requirement hour, impeller diameter is bigger, and runner is very narrow, can not satisfy the casting technique requirement, can only adopt the way of amplified flow, widens runner, and pump just can not move efficiently putting like this.Have in the chemical-process technology much to require flow little, be lower than 1.2m
3/ h, and the lift requirement is very high, like this can only be at pump discharge opening bypass conduit line, most of medium back flow has only small part to enter in the technological process and goes in the pump intake jar, and unit efficiency is too low, increased the expense of bypass line again, existing canned motorpump needs to adopt different structure according to fed sheet of a media temperature difference, and the serviceability temperature scope of same model canned motorpump is little.At existing problem in the above-mentioned prior art, a kind of novel vortex canned motorpump of research and design, existing problem is very necessary in the prior art thereby overcome.
Summary of the invention
In view of existing problem in the above-mentioned prior art, the purpose of this utility model is a kind of novel vortex canned motorpump of research and design, requires canned motorpump problem high, that traffic requirement is little, temperature range is big, liquid is carried in the nothing leakage thereby solve lift.Vortex canned motorpump described in the utility model is by the pump housing, impeller, motor, housing, front-end bearing pedestal, rear bearing block, heat exchanger, form; It is characterized in that the described pump housing, impeller adopt the pump housing and the impeller of peripheral pump structure, described motor adopts shield electric machine, described shield electric machine comprises stator module and rotor assembly, stator module is installed among the housing, the forward flange of housing one end is connected with the pump housing with front-end bearing pedestal, and the rear flange of the other end is connected with rear bearing block; Rotor assembly is installed on the housing stator module shaft axis by front-end bearing pedestal, fore bearing, front shaft sleeve and rear bearing block, rear bearing, rear axle housing; The axle front end of rotor assembly stretches into the pump housing and is connected with impeller by flat key; Pipeline one end of heat exchanger is connected to rear bearing block, and the other end is connected to the lateral orifices of forward flange.Stator can is equipped with in the outer survey of the stator iron core of stator module described in the utility model and staor winding.Rotor can is equipped with in the outer survey of the cast-aluminum rotor of rotor assembly described in the utility model; The shaft rear end of described rotor assembly is equipped with pays impeller.Heat exchanger described in the utility model is formed by bimetallic tube dish system.The shaft rear end center of described rotor assembly is drilled with center hole, is drilled with side opening on the position that pair impeller is housed
The stator module and the rotor assembly of vortex canned motorpump described in the utility model are provided with housing, and this housing forms one and makes the space that isolates between described stator and the described rotor, does not corrode rotor so that from then on circulating liquid flows through.Stator module is connected with the pump housing, the shared axle of impeller and rotor assembly, and impeller is fixed on the rotor shaft with a flat key, only with play.Flange, stator can, stator core winding, junction box seat before and after stator module comprises.Rotor assembly comprises axle, rotor iron core, Rotor can, front and rear cover plate, pays impeller.Described heat exchanger is formed by bimetallic tube dish system.The pump housing and impeller constitute an active chamber, and stator module and rotor assembly and heat exchanger constitute an active chamber, and two active chambers communicate, because middle damping function, both sides liquid is mixed hardly.
The problem of the required solution of the utility model provides a kind of vortex canned motorpump, the characteristics of this vortex canned motorpump be small flow, high-lift, the serviceability temperature scope is big, minimum discharge is 0.1m
3/ h, and without the opening bypass conduit line, lift can reach 200m, serviceability temperature scope normal temperature to 350 ℃.
The present invention compared with the prior art, tool is in following advantage:
1, with existing peripheral pump ratio, though all have small flow, high-lift characteristics, but existing peripheral pump is owing to adopt mechanical seal to carry out shaft sealing, the inevitable existence leaks, and the shared axle of vortex canned motorpump and motor, do not have motive sealing, can not have fully to leak and carry poisonous, the valuable liquid of burn into.
2, existing canned motorpump all is to adopt receded disk impeller, and its minimum continuous flow is bigger, when the technology traffic requirement is very little, just must offer bypass, increases mounting cost.In addition, increased the volumetric loss of pump, the effective efficiency of pump reduces, and increases capacity motor, has also just increased power consumption.The utility model adopts the vortex canned motorpump, and these problems can be avoided entirely.
3, require when high-lift, existing canned motorpump can only adopt multi stage pump, and volume is big, and structure is also complicated.The vortex shield pump structure is simple, volume is little, in light weight, the maintenance convenient and simple.
4, pump chamber and motor cavity are two independently active chambers, and the temperature of pump fed sheet of a media can not exert an influence to the temperature in the motor cavity, so its fed sheet of a media temperature range is big, the highest can be from normal temperature to 350 ℃.
5, impeller can play on axle, and the end thrust of rotor is almost nil, has improved the working life of bearing.
The utlity model has novel structure, volume is little, lift is high, do not have to leak, the efficient advantages of higher, it puts goods on the market in enormous quantities and will produce positive social benefit and remarkable economic efficiency.
