The many employings of existing magnetic drive pump are horizontal, the structure of sliding bearing, need the medium cooling and lubricating, need connect liquid during pump startup, and particularly poisonous and harmful pollution, volatile medium have very big difficulty when connecing liquid; Existing magnetic drive pump all can only be carried and not contain solid particle, gas-free cleaning medium, all must not the aneroid no load running; The defective that the eddy current heat that the magnetic field intercepts magnetic line of force produces when turning round between magnet rotor and the outer magnet rotor in existing magnetic drive pump all exists can't dispel the heat, thereby cause losing efficacy because the hot height of eddy current causes the magnet steel demagnetization, lubricant medium vaporize because eddy current heat is high cause lubricated not freely, sliding bearing and thrust bearing wear and tear problems such as the rate of fault height of pump easily.
Summary of the invention:
Purpose of the present invention will provide shurry pump under a kind of vertical nitrogen sealing gland cooling magnetic force liquid exactly, compact structure of the present invention, long service life, the transmission moment of torsion is big, transmission efficiency is high, stable and reliable operation, convenient for installation and maintenance, maintenance expenses is little and can do running.
The present invention realizes like this, shurry pump under a kind of vertical nitrogen sealing gland cooling magnetic force liquid, comprise the pump housing, bearing support, pump cover, it is characterized in that: be provided with pump shaft by bearing in the described bearing support, be connected with nitrogen interface by aperture on the bearing support, be provided with upper connecting tube above the bearing support, be provided with motor above the upper connecting tube, the flange of upper connecting tube is arranged on the mounting plate; Be provided with lower linking tube below the bearing support, be provided with the pump housing below the lower linking tube, pump housing side is connected with drain pipe by flange; Be provided with impeller in the pump housing of described pump shaft below and reach the fixedly impeller nut of impeller; Magnet rotor assembly in being provided with in the upper connecting tube of pump shaft top, interior magnet rotor assembly outer ring is provided with separation sleeve, and the separation sleeve top is provided with outer magnet rotor assembly, and outer magnet rotor assembly is connected on the axle of motor.
Compact structure of the present invention, long service life, the transmission moment of torsion is big, transmission efficiency is high, stable and reliable operation, convenient for installation and maintenance, maintenance expenses is little and can do running.

Embodiment:
The present invention is further illustrated below in conjunction with accompanying drawing:
With reference to accompanying drawing, shurry pump under a kind of vertical nitrogen sealing gland cooling magnetic force liquid, comprise the pump housing 1, bearing support 6, pump cover 3, it is characterized in that: be provided with pump shaft 7 by bearing 17 in the described bearing support 6, be connected with nitrogen interface 18 by aperture on the bearing support 6, be provided with upper connecting tube 13 above the bearing support 6, be provided with motor 12 above the upper connecting tube 13, the flange of upper connecting tube 13 is arranged on the mounting plate 14; Be provided with lower linking tube 5 below the bearing support 6, be provided with the pump housing 1 below the lower linking tube 5, the pump housing 1 side is connected with drain pipe 4 by flange; Be provided with impeller 2 in the described pump shaft 7 below pump housings 1 and reach the fixedly impeller nut 20 of impeller 2; Magnet rotor assembly 8 in being provided with in the pump shaft 7 top upper connecting tubes 13, interior magnet rotor assembly 8 outer rings are provided with separation sleeve 11, and separation sleeve 11 tops are provided with outer magnet rotor assembly 10, and outer magnet rotor assembly 10 is connected on the axle of motor 12.During concrete enforcement, the magnetic force contactless transmission device that the present invention adopts extraordinary intensity, magneticfocusing, the push-and-pull magnetic circuit of special magnetic circuit design method design to be coupled, therefore the magnetic transmission efficiency is higher by 5～10% than similar magnetic driver, has compact structure, volume is little, torque is big, eddy current is little, magnetic transmission efficiency advantages of higher; Adopt nitrogen cooling and lubricating rolling bearing, and reach the gas seal function, prevent that medium steam from leaking, stop the fed sheet of a media contact bearing, fed sheet of a media can be slurry and impure more medium.Use the patent of invention patent No. of my company: ZL 2,009 1 0231778.2 simultaneously, the special nonmetallic material separation sleeve of making, the specific resistance of nonmetal isolating sleeve is infinitely great, the on-stream eddy current heat that do not produce, need not adopt cooling liquid to cool off interior magnet rotor, take away the eddy current heat, the temperature of therefore inside and outside magnet rotor can not raise and cause the demagnetization phenomenon, guarantees that magnetic force contactless transmission device has higher transmission efficiency and operation stability, makes magnetic force contactless transmission device can do running.Adopt the static seal gasket seal to guarantee not have any leakage, make this pump do running and can reach 3 years.This pump adopts no grease lubrication rolling bearing to replace the sliding bearing that contacts with medium in the common magnetic drive pump.The radial force that rolling bearing can bearing pump produces during operation and the residual axial force after balance make pump operation more reliable and more stable; The radial force that sliding bearing can only bearing pump produces during operation, thrust bearing can only bear very small bearing.Adopt the bearing support that lengthens to increase the axial distance between the two bearings, the structure of shortening shaft extension jib-length, any sliding bearing is not set on the revolving part, can improve stability and the reliability of pump operation effectively.Adopt the cooling of nitrogen sealing gland between bearing, but cooling and lubricating bearing and inside and outside magnet rotor can prevent effectively that medium steam from leaking, stoping the fed sheet of a media contact bearing, have realized dried running, prolong the working life in cycle of pump.The back side of main impeller is provided with back blade, reduces the impeller back pressure in the pump operation process; Concurrently injected dry gas inlet pressure exceeds 0.2MPa than material pressure, can stop the steam of fed sheet of a media to leak, touch bearing, reaches the effect of the bearing that adequately protects.Magnet rotor rotation in motor of the present invention drives by outer magnet rotor assembly by the rotation of pump shaft impeller, is transported to outlet with medium from import.The medium that shurry pump is widely used in carrying poisonous and harmful medium, height to contain solid particle medium, high gassiness in the production procedure in fields such as chemical industry, oil, refinery, pharmacy under the vertical nitrogen sealing gland cooling magnetic force liquid, near the boiling point medium, contain toxic gas medium, inflammable and explosive medium and Korrosionsmedium, be specially adapted to the conveying of titanium sponge industry essence, thick TiCl4 slurries and other industrial and minerals, chemical industry slurry medium and need to do the operating mode of running.
