Abstract
A horizontal-type magnetic drive pump comprises a pump shaft, an inner magnetic rotor assembly and an isolation sleeve. An impeller is arranged in an inner chamber formed by a pump body and a pump cover and sheathed on the pump shaft, and the top end is locked by an impeller nut; the right end of the pump cover is connected with a bearing pedestal; in an inner chamber of the bearing pedestal, a bearing B is arranged at the upper left end of the pump shaft, a bearing A is arranged at the right end thereof, and a nitrogen inlet is formed below the left end of the bearing pedestal; and the right end of the bearing pedestal is connected with a connecting frame, the inner magnetic rotor assembly is arranged in the center of an inner chamber of the connecting frame and sleeved with the isolation sleeve, an outer magnetic rotor assembly is arranged on the outer ring of the isolation sleeve, and a motor is arranged at the right end of the connecting frame. The horizontal-type magnetic drive pump adopts a power sealing structure and reduces the pressure of materials and the impeller back end. Nitrogen sealing is adopted between the bearings, so that the leakage of medium steam is prevented, and the heat radiated between the bearings and the outer and the inner magnetic rotor assemblies is cooled. The horizontal-type magnetic drive pump has the advantages of adoption of a ceramic isolation cover, no electromagnetic eddy, demagnetization, prolongs the service life of the pump, and reduces the cost.
Description
Technical field: the utility model relates to a kind of horizontal magnetic pump.
Background technique: magnetic drive pump be widely used in fields such as chemical industry, oil, refinery, pharmacy poisonous, contain solid particle medium, contain the toxic gas medium, near the conveying of boiling point medium.Because the magnetic driving equipment that adopts extraordinary intensity, magneticfocusing, push-and-pull magnetic circuit to be coupled, has compact structure, volume is little, torque is big, eddy current is little, magnetic transmission efficiency advantages of higher.But the defective that the eddy current heat that the magnetic field intercepts magnetic line of force is produced when turning round between magnet rotor and the outer magnet rotor in existing can't dispel the heat, and the separation sleeve that does not adopt separation sleeve between them or adopted is metal, heat of magnetic force is gathered, caused the magnet steel demagnetization.Magnetic driving equipment also exists leakage, and the impeller backside pressure is big in the pump operation, is provided with sliding bearing phenomenon easy to wear in the medium, has shortened the working life of pump greatly.
Summary of the invention: the purpose of this utility model will provide a kind of horizontal magnetic pump exactly, and it can overcome the existing problem of above product well.The purpose of this utility model is to realize like this, a kind of horizontal magnetic pump, formed by pump shaft, interior magnet rotor assembly, separation sleeve, it is characterized in that: be provided with impeller in the inner chamber that the pump housing and pump cover form, described impeller set is on pump shaft, the top is locked by impeller nut, and the other end is provided with axle sleeve; The right-hand member of pump cover connects with bearing support, and in the inner chamber of bearing support, left end is provided with bearing B on the pump shaft, and right-hand member is provided with bearing A, and respectively by bearing gland sealing, bearing sleeve supporting, the left end below of bearing support also is provided with nitrogen inlet; Described bearing support right-hand member connects with link press span, and in the inner chamber of link press span, central authorities are provided with interior magnet rotor assembly, and are with separation sleeve, and the separation sleeve outer ring is provided with outer magnet rotor assembly; Described link press span below is provided with leg, and right-hand member is provided with motor.The utility model adopts the dynamic seal structure, reduces material impeller is carried on the back end pressure.Can prevent that with the nitrogen sealing gland medium steam from leaking between bearing, and don't contact medium; No grease lubricating bearing, dried running can reach 3 years, and cooling bearing and outer magnet rotor assembly, interior magnetic change the heat radiation between the part assembly simultaneously.The pottery shielding can, no electromagnetic eddy, demagnetization.Prolong the working life of pump, reduced maintenance cost.
Description of drawings:
Fig. 1 is the utility model structural representation;
1. impeller nut, the 2. pump housing, 3. impeller, 4. pump cover, 5. gland, 6. axle sleeve, 7. bearing support, 8. pump shaft, 9. in magnet rotor assembly, 10. separation sleeve, 11. link press span, 12. outer magnet rotor assemblies, 13. motors, 14. leg, 15. bearing sleeves, 16. bearing A, 17. bearing B, 18. bearing glands, 19. nitrogen inlet.
Embodiment: the utility model is described in further detail below in conjunction with accompanying drawing;
A kind of horizontal magnetic pump, be made up of pump shaft 8, interior magnet rotor assembly 9, separation sleeve 10, it is characterized in that: be provided with impeller 3 in the inner chamber that the pump housing 2 and pump cover 4 form, described impeller 3 is enclosed within on the pump shaft 8, the top is by impeller nut 1 locking, and the other end is provided with axle sleeve 6; The right-hand member of pump cover 4 connects with bearing support 7, in the inner chamber of bearing support 7, left end is provided with bearing B17 on the pump shaft 8, and right-hand member is provided with bearing A16, and respectively by bearing gland 18 sealings, bearing sleeve 15 supportings, the left end below of bearing support 7 also is provided with nitrogen inlet 19; Described bearing support 7 right-hand members connect with link press span 11, and in the inner chamber of link press span 11, central authorities are provided with interior magnet rotor assembly 9, and are with separation sleeve 10, and separation sleeve 10 outer rings are provided with outer magnet rotor assembly 12; Described link press span 11 belows are provided with leg 14, and right-hand member is provided with motor 13.During concrete enforcement, adopt the dynamic seal structure, reduce material impeller is carried on the back end pressure.Be respectively arranged with O type circle and oil sealing in pump cover and axle sleeve contacting point and with the bearing support connection place.Magnet rotor assembly outside on motor shaft, putting, radially by screw location, axially by baffle plate and screw on motor shaft.Magnet rotor assembly in the right-hand member of pump shaft puts, the left end of interior magnet rotor assembly are regulated by nut and are supported, and the periphery of interior magnet rotor assembly is covered with separation sleeve, puts motor at last, and connects with bearing support, leg.Described separation sleeve is to adopt special nonmetallic material ceramic making, and the eddy current heat that the magnetic field intercepts magnetic line of force is produced when turning round between magnet rotor and the outer magnet rotor in it can be isolated can not produce heat of magnetic force and gathers, and has improved the working life of pump.
When driven by motor cover outer magnet rotor assembly thereon rotates, magnetic changeed the rotation of part drive pump shaft in outer magnet rotor assembly made, bearing A, bearing B is supporting pump shaft, the magnetic field intercepts magnetic line of force will produce the eddy current heat when turning round between interior magnet rotor and the outer magnet rotor, the too high meeting of eddy current heat causes the magnet steel demagnetization, sliding bearing and thrust bearing wear and tear easily, at this moment pass through nitrogen interface, by bearing support passage input nitrogen, because nitrogen inlet is than the high 0.2MPa of material inlet pressure, so can stop the medium contact bearing, can reach outer magnet rotor assembly by cooling bearing again simultaneously, interior magnetic changes the heat radiation between the part assembly.
