Description
Technical field
The utility model relates to a kind of electromagnetic pump, particularly a kind of electromagnetic pump that directly drives.
Background technique
In industries such as oil-refining chemicals, chemical liquid belongs to inflammable, explosive, poisonous, hazardous medium in case earial drainage will cause very big harm, in the extraction of this liquid is carried, can not use the general industry pump, use the magnetic drive pump of anti-heads.Magnetic drive pump replaces motive sealing with static seal; Between the interior magnet steel of magnetometric sensor and outer steel, a separation sleeve is set; The interior magnet steel of the pump housing and magnetometric sensor is closed; Make the flow passage components of pump be in complete sealing state, thoroughly solved mechanical seal unavoidable " run, drip, leak " problem of other pump, eliminated the potential safety hazard that the oil-refining chemical industry is inflammable, explosive, poisonous, hazardous medium leaks through pump seal.
Existing magnetic drive pump is made up of pump, magnetic driver, separation sleeve and motor four parts.The critical component magnetic driver is made up of outer magnet rotor, interior magnet rotor and non-magnetic separation sleeve.When magnet rotor outside the motor drives rotated, magnetic field energy penetrated air gap and namagnetic substance, drove the interior magnet rotor that links to each other with impeller and did rotation synchronously, and the non contact transmission of realization power is converted into static seal with motive sealing.
Existing magnetic drive pump mechanism complicacy, Heavy Weight, volume be big, connect transition piece many, reduced assembly precision, increased manufacture cost, the rate of fault height, cost is high, efficient is low, operating cost is high.
Summary of the invention
The technology of the utility model is dealt with problems and is: the deficiency that overcomes existing technology; A kind of electromagnetic pump that directly drives is provided, and this electromagnetic pump is integrated magnetic driver and motor two-part of traditional magnetic drive pump, and separation sleeve is isolated the stator of motor with the motor rotor and the pump housing; Prevent leak of liquid; The moment of torsion that motor stator produces directly drives the impeller work of the pump housing, no longer needs magnetic driver to carry out transition, forms directly to drive electromagnetic pump.
The technical solution of the utility model is: directly drive electromagnetic pump; Be characterized in: directly drive electromagnetic pump and form by pump housing part and motor portion and separation sleeve three parts; Motor in traditional electrical magnetic pumping part partly is integrated with magnetometric sensor; The outer steel that is about to magnetometric sensor in the traditional electrical magnetic pumping directly replaces with motor stator, and the interior magnet steel of magnetometric sensor in the traditional electrical magnetic pumping is directly replaced with rotor.Be pressed in the motor case 1 after stator iron core 2 laminates, staor winding 3 is placed in the stator iron core 2, is pressed on the motor shaft 5 after rotor iron core 8 laminates, and permanent-magnet steel 9 is installed on rotor iron core 8; On motor shaft 5, have keyway; Lay connecting key 7, motor shaft 5 links together with impeller 14, and fixing with gland nut 13; Separation sleeve 11 outers are connected with motor front cover 12 with motor case 1 respectively; The internal fixation motor rear bearing 6 of separation sleeve 11, the motor fore bearing 10 on being placed in motor front cover 12, the weight of support motor rotor and impeller.The stator of motor stator and conventional motors is similar, and the rotor of motor is the permanent magnet magnet steel, and separation sleeve is arranged between motor stator and the rotor, prevents to carry liquid to spill from motor side.
The working principle of the utility model is: after motor stator winding 3 is connected electrical network; In motor stator core 2, produce rotating magnetic field; The generation torque that intercouples of magnetic field that separation sleeve 11 and rotor permanent-magnet steel 9 produce is passed in this magnetic field; The rotation of drive rotor, thus drive 14 rotations of pump housing impeller, extract and carry liquid.
The utility model advantage compared with prior art is: directly drive electromagnetic pump the magnetic driver and the motor of traditional magnetic drive pump is integrated, simplified the shortening greatly of complete machine mechanism, axial length, smaller volume, weight and significantly reduced.Because connecting transition piece reduces, has effectively improved assembly precision, has improved the complete machine performance; Reduced vibrations and noise, improved complete machine working life, after transmission link reduces; Reduced power loss, improved utilization rate of electrical, reduced manufacture cost, reduced buying expenses.
Description of drawings
Fig. 1 is the electromagnetic pump structural representation that directly drives of the present invention.
Embodiment
The described electromagnetic pump that directly drives of the utility model; As shown in Figure 1, mainly form by motor case 1, motor stator core 2, motor stator winding 3, back end cover for motor 4, motor shaft 5, motor rear bearing 6, connecting key 7, motor rotor core 8, permanent-magnet steel 9, motor fore bearing 10, separation sleeve 11, motor front cover 12, gland nut 13, impeller 14, seal ring 15, pump case 16.
Be pressed in the motor case 1 after stator iron core 2 laminates, staor winding 3 is placed in the stator iron core 2.Be pressed in after rotor iron core 8 laminates on the motor shaft 5, permanent-magnet steel 9 is installed on rotor iron core 8, on motor shaft 5, have keyway, lay connecting key 7, the torsion that electric machine iron core 8 is received passes to motor shaft 5.Motor shaft 5 links together with impeller 14, and fixing with gland nut 13, and impeller 14 together rotates with motor shaft 5, extracts liquid.Separation sleeve 11 is the critical components that directly drive electromagnetic pump, is tubular structure, and its outer is connected with motor front cover 12 with motor case 1 respectively, avoids carrying liquid to get in the motor stator, prevents the liquid earial drainage.The internal fixation motor rear bearing 6 of separation sleeve 11, the motor fore bearing 10 on being placed in motor front cover 12, the weight of support motor rotor and impeller.4 pairs of motors of back end cover for motor play protective action, pump case 16 except that with also be used for water conservancy diversion motor partly is connected and carry liquid.
The separation sleeve 11 of the utility model has three functions, and the one, isolate and carry liquid, the rotor part partly is included in the pump housing; And it is isolated with motor stator; Prevent to carry liquid to get in the motor stator, damage motor windings, and prevent to carry liquid to flow out from the motor end.The 2nd, the support motor rotor weight keeps the electric machine rotor air gap even, makes the motor proper functioning.The 3rd, can not shielding magnetic field, guarantee that the rotating magnetic field that motor stator produces arrives rotors through separation sleeve 11 smoothly.Therefore the material of separation sleeve 11 must have that very high intensity, corrosion resistance are good, leakage proof, non-magnetic conduction.Be in because of separation sleeve 11 between the rotor of motor, be in all the time in the high magnetic fields, separation sleeve 11 is used non-conducting material and is processed, and avoids forming circulation along magnetic shield.Therefore the comparatively suitable material of separation sleeve is that corrosion-resistant, high-intensity engineering plastics, diamond spar pottery, stainless steel are as manufactured materials.
