Description
Technical field
The utility model relates to a kind of magnetic drive pump, particularly a kind of magnetic drive pump of architecture advances.
Background technique
Magnetic drive pump is different from traditional canned pump, motor crankshaft is not directly connected with pump shaft, but motor crankshaft drives outer magnet rotor to rotate, and outer magnet rotor and interior magnet rotor fit through magnetic force and drive interior magnet rotor to rotate, drive pump shaft to rotate by interior magnet rotor, make the vane rotor rotation work on pump shaft.The Seal cage that separation sleeve is formed is provided with between inner magnet rotor of magnetic drive pump and outer magnet rotor, pump shaft and interior magnet rotor are enclosed in Seal cage, one can avoid liquid by pump shaft end externally seepage, two can cool pump shaft and interior magnet rotor, therefore without the need to taking traditional dynamic seal (packing) just can obtain very excellent No leakage characteristic to pump shaft, thus be widely used in carrying various severe toxicity, the danger medium such as inflammable, explosive, play important function in fields such as oil, chemical industry, medicine, nuclear power, national defence.
Impeller due to material uneven, the accumulation of blank defect, machining error, assembly error etc., and the asymmetry geometrical shape etc. existed during design, make its non-uniform mass, form certain bias, when the impeller is rotated, produce unbalanced centrifugal inertia force, thus making pump produce vibration and noise, the bad expected service life that can reduce equipment of dynamic balancing, shows the earlier period damage of bearing especially, the maintenance period of shortening equipment, the maintenance cost of increase equipment, affects quality of product, aggravating working environment etc.
Summary of the invention
In order to solve the problem that above-mentioned prior art is difficult to overcome, the utility model provides a kind of magnetic drive pump of architecture advances, comprise the pump housing 1, pump cover 3, pump shaft 7, impeller 2, interior magnet rotor 5, outer magnet rotor 6, separation sleeve 4, interior magnet rotor 5 is fixedly mounted on pump shaft 7 axle head, outer magnet rotor 6 is arranged on motor shaft end, between interior magnet rotor 5 and outer magnet rotor 6, separation sleeve 4 is set, separation sleeve 4 and pump cover 3 body seal are fixedly connected, the described pump housing 1, pump cover 3 and separation sleeve 4 are connected into entirety, the pump chamber that composition is closed, it is characterized in that: the pump housing 1 inwall installs tapered roller bearing 8 with coordinating between impeller 2, pump shaft 7 is supported by axial contact bearing 9 and radial contact bearing 10 and is installed in pump chamber.
Impeller 2 has impeller groove 11 near the pump housing 1 inwall side, and the pump housing 1 inwall has pump housing groove 12, coordinates and install tapered roller bearing 8 between impeller groove 11 and pump housing groove 12.
The beneficial effects of the utility model are: magnetic drive pump pump shaft 7 and impeller 2 are supported by tapered roller bearing 8, axial contact bearing 9 and radial contact bearing 10 and install in pump chamber, the dynamic balancing that the magnetic drive pump of this structure effectively can control impeller 2 is bad, the axial float of effective control pump shaft 7 impeller 2, increase magnetic drive pump useful life longevity, improve magnetic drive pump operational reliability and Security.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
