Abstract
The invention relates to a corrosion-resistant pipeline pump. Resin for corrosion resistance and insulation is poured in cavities of a winding and a motor stator core. The corrosion-resistant pipeline pump comprises a pipeline pump casing, a rotor and a magnetic bearing, a screw blade is attached to the inner wall of the rotor in a hollow structure, and the rotor and the pipeline pump casing are connected through the magnetic bearing. By means of the integrally-poured stator structure, a shielding sleeve in a traditional shielding pump is omitted, the motor efficiency can be improved by about 30% while the thermal conductivity of resin is greatly improved as compared with that of the air, cooling effect of the end of the motor winding is improved, power density of the motor is greatly improved, and accordingly compactness of the pipeline pump is further improved. Super-compact integral design of the motor and the pipeline pump can be realized by the aid of the structure that the screw blade is arranged in the inner periphery of the motor rotor, and connection of the pipeline pump with a pipeline is facilitated. In addition, a traditional oiling bearing is substituted by the magnetic bearing, and accordingly the problem of corrosion of the bearing is solved.
Description
Technical field

Background technique
Existing pipeline mounted pump is the structure that motor separates with pump, although this structure can realize modularization, is unfavorable for compact designed, is unsuitable for the application high to spatial requirement.And traditional shield pump structure, although this structure has realized motor and pump integrated design, but still be traditional motor and the coaxial structure that is connected of pump, really do not realize compact designed, simultaneously owing to adopt stainless steel shielding cover to isolate the rotor of motor in the motor gas-gap, therefore housing can produce a large amount of eddy current loss the in service of motor, so the electric efficiency of this kind structure only about 60%, thereby has caused the significant wastage of the energy.
Summary of the invention
The present invention will provide a kind of corrosion resistant pipeline mounted pump, and this pipeline mounted pump is integrated by the rotor that adopts propeller blade and motor, the structural type of integrated casting type stator and magnetic suspension bearing, has realized the ultra-compact structure of anticorrosion pipeline pump.
For achieving the above object, technological scheme of the present invention is: a kind of corrosion resistant pipeline mounted pump, comprise electric machine stator iron, and embed winding in the electric machine stator iron, be characterized in: cast is used for the resin of corrosion protection and insulation in the cavity of electric machine stator iron and winding.
Corrosion resistant pipeline mounted pump also comprises pipeline mounted pump casing, rotor, and magnetic suspension bearing, rotor are hollow structure, and its inwall is with propeller blade, and the outer rim of propeller blade is by welding or be bolted to the inner circle of rotor; Be connected by magnetic suspension bearing between rotor and the pipeline mounted pump casing.
Magnetic suspension bearing comprises axial magnetic suspension bearing and radial magnetic bearing, wherein axial magnetic suspension bearing is arranged between the axial boss and pipeline mounted pump casing of rotor, the axially locating that is used for rotor, offset the axial reaction force that the propeller blade rotation produces, radial magnetic bearing is arranged between the external diameter and pipeline mounted pump casing of rotor, is used for the radial location of rotor.
The two ends of pipeline mounted pump casing are respectively equipped with the pipeline thread for connecting tube.
The invention has the beneficial effects as follows:
(1) adopts the integrated casting type stator structure, abandoned the housing in traditional canned motorpump, can improve electric efficiency about 30%, resin-phase improves greatly than the thermal conductivity of air simultaneously, improved the cooling effect of electric motor winding end, greatly improve the specific power of motor, thereby further improved the compactedness of pipeline mounted pump; (2) adopt propeller blade to be built in the structure of rotor internal diameter, can realize the ultra-compact integrated design of motor and pipeline mounted pump, make things convenient for simultaneously the interface of pipeline mounted pump and pipeline;
(3) by adopting magnetic suspension bearing, cancel traditional oil-lubricated bearing, do not had the grease leakage pollution problem of bringing because of the oil sealing breakage, solved simultaneously the corrosion-resistant problem of bearing.
The present invention adopts the design of pump and motor integration, in conjunction with integrated casting type stator and magnetic suspension bearing, thereby reaches the purpose of corrosion-resistant and ultra-compact design.
