The many employings of existing magnetic drive pump are horizontal, the structure of sliding bearing, it is necessary to medium cooling and lubricating, need to connect liquid during pump startup, particularly poisonous and harmful pollution, volatile medium, have very big difficulty when connecing liquid；Existing magnetic drive pump all can only be carried without solid particle, gas-free cleaning medium, all must not aneroid dry run；The defect that when existing magnetic drive pump all also exists operating between interior magnet rotor and outer magnet rotor, eddy current heat produced by the magnetic field intercepts magnetic line of force cannot dispel the heat, thus causing because eddy current heat height causes magnet steel demagnetization to lose efficacy, lubricant medium vaporize because eddy current heat is high the problem such as cause that lubrication is smooth, sliding bearing and thrust bearing easily wear and tear, the fault rate height of pump.
Summary of the invention:
Present invention aim to provide shurry pump under a kind of vertical nitrogen sealing gland cooling magnetic liquid, present configuration is compact, long service life, transmission moment of torsion is big, transmission efficiency is high, stable and reliable operation, convenient for installation and maintenance, maintenance cost is little and can do operating.
The present invention is realized in, shurry pump under a kind of vertical nitrogen sealing gland cooling magnetic liquid, including the pump housing, bearing block, pump cover, it is characterized in that: in described bearing block, bearing is provided with pump shaft, bearing block is connected to nitrogen interface by aperture, bearing block is provided above with upper connecting tube, and upper connecting tube is provided above with motor, and the flange of upper connecting tube is arranged on a mounting board；Bearing block is provided below lower linking tube, and lower linking tube is provided below the pump housing, and there is drain pipe pump housing side by Flange joint；The impeller nut of impeller and fixing impeller it is provided with in the pump housing below described pump shaft；Being provided with interior magnetic rotor component above pump shaft in upper connecting tube, interior magnetic rotor component outer ring is provided with separation sleeve, and separation sleeve is provided above outer magnetic rotor component, and outer magnetic rotor component is connected on the axle of motor.
Present configuration is compact, long service life, transmission moment of torsion is big, transmission efficiency is high, stable and reliable operation, convenient for installation and maintenance, maintenance cost is little and can do operating.

Detailed description of the invention:
Below in conjunction with accompanying drawing, the present invention is further illustrated:
With reference to accompanying drawing, shurry pump under a kind of vertical nitrogen sealing gland cooling magnetic liquid, including the pump housing 1, bearing block 6, pump cover 3, it is characterized in that: in described bearing block 6, bearing 17 is provided with pump shaft 7, bearing block 6 is connected to nitrogen interface 18 by aperture, bearing block 6 is provided above with upper connecting tube 13, and upper connecting tube 13 is provided above with motor 12, and the flange of upper connecting tube 13 is arranged on installing plate 14；Bearing block 6 is provided below lower linking tube 5, and lower linking tube 5 is provided below the pump housing 1, and there is drain pipe 4 pump housing 1 side by Flange joint；The impeller nut 20 of impeller 2 and fixing impeller 2 it is provided with in the pump housing 1 below described pump shaft 7；Being provided with interior magnetic rotor component 8 above pump shaft 7 in upper connecting tube 13, interior magnetic rotor component 8 outer ring is provided with separation sleeve 11, and separation sleeve 11 is provided above outer magnetic rotor component 10, and outer magnetic rotor component 10 is connected on the axle of motor 12.When being embodied as, the present invention adopts the magnetic force non-contact transmission mechanism that extraordinary intensity that special magnetic circuit design method designs, magneticfocusing, push-and-pull magnetic circuit are coupled, Magnetic drive efficiency is higher than similar magnetic driver by 5～10%, therefore has compact conformation, volume is little, torque is big, eddy current is little, Magnetic drive efficiency advantages of higher；Adopting nitrogen cooling and lubricating rolling bearing, and reach air seal function, it is prevented that medium steam leaks, stop pumped (conveying) medium contact bearing, pumped (conveying) medium can be slurry and impure more medium.Simultaneously with the patent of invention patent No. of my company: ZL200910231778.2, the special nonmetallic materials separation sleeve made, the resistivity of nonmetal isolating sleeve is infinitely great, on-stream do not produce eddy current heat, do not need to adopt coolant to cool down interior magnet rotor, to take away eddy current heat, therefore the temperature of inside and outside magnet rotor will not raise and cause demagnetization phenomenon, it is ensured that magnetic force non-contact transmission mechanism has higher transmission efficiency and operation stability, makes magnetic force non-contact transmission mechanism can do operating.Adopt static gasket to seal and guarantee without any leakage so that the dry operating of this pump was up to 3 years.This pump adopts and instead of, without grease lubrication rolling bearing, the sliding bearing contacted with medium in common magnetic drive pump.The radial force that rolling bearing produces when can bear pump operation and the residual axial force after balance, make pump operation more stable reliably；The radial force that sliding bearing produces when can only bear pump operation, thrust bearing can only bear very small bearing.Adopt the axial distance between the bearing block lengthened increase two bearings, shortening axle to stretch the structure of jib-length, revolving part is not provided with any sliding bearing, stability and the reliability of pump operation can be effectively improved.Adopt the cooling of nitrogen sealing gland between bearing, can cooling and lubricating bearing and inside and outside magnet rotor, medium steam can be effectively prevented and leak, stop pumped (conveying) medium contact bearing, it is achieved that dry operating, extend the service life in cycle of pump.The back side of main impeller is provided with back blade, reduces the impeller back pressure in pump operation process；Concurrently injected dry gas feed pressure ratio material pressure exceeds 0.2MPa, and the steam of pumped (conveying) medium can be stoped to leak, touch bearing, the effect of the bearing that reaches to adequately protect.In motor of the present invention is driven by outer magnetic rotor component, magnet rotor rotates, and is rotated by pump shaft impeller, from import, medium is transported to outlet.Under vertical nitrogen sealing gland cooling magnetic liquid shurry pump be widely used in the production procedure in the fields such as chemical industry, oil, refinery, pharmacy carrying poisonous and harmful medium, high containing solid particle medium, high gassiness medium, close to boiling point medium, containing toxic gas medium, inflammable and explosive medium and Korrosionsmedium, be particularly well-suited to titanium sponge industry TiCl4 serosity smart, thick and other industrial and minerals, the conveying of chemical industry slurry medium and the operating mode of operating need to be done.
