A tapered roller bearing (8) is installed between the inner wall of a pump body (1) and an impeller (2) in a matching mode, and a pump shaft (7) is installed in a pump cavity in a supporting mode through an axial contact bearing (9) and a radial contact bearing (10). According to the magnetic pump with the improved structure, bad dynamic balance of the impeller (2) can be effectively controlled, axial displacement of the pump shaft (7) and the impeller (2) can be effectively controlled, the using durability of the magnetic pump can be enhanced, and the running reliability and safety of the magnetic pump can be improved.
Description
Technical field
The present invention relates to a kind of magnetic drive pump, the improved magnetic drive pump of particularly a kind of structure.
Background technology
Magnetic drive pump is different from traditional canned pump, and motor crankshaft is not joined directly together with pump shaft, but motor crankshaft drives outer magnet rotor rotation, outer magnetic
Rotor and interior magnet rotor fit through magnet rotor in magnetic force drive and rotate, and drive pump shaft rotation by interior magnet rotor, make the vane rotor on pump shaft rotate work
Make.It is provided with the annular seal space of separation sleeve formation between inner magnet rotor of magnetic drive pump and outer magnet rotor, pump shaft and interior magnet rotor are enclosed in annular seal space, one can
Avoid liquid from pump shaft end to outboard leak, two can cool down to pump shaft and interior magnet rotor, therefore just need not take traditional dynamic sealing to pump shaft
Very excellent No leakage characteristic can be obtained, thus be widely used in conveying the various danger medium such as hypertoxic, inflammable, explosive, oil, chemical industry,
The fields such as medicine, nuclear power, national defence have played important function.
Impeller is uneven due to material, the accumulation of blank defect, machining error, rigging error etc., and the asymmetry geometry existing during design
Shape etc., so as to non-uniform mass, forms certain bias, when the impeller is rotated, produces unbalanced centrifugal intertia force, so that pump produces
Raw vibration and noise, the bad expected service life that can reduce equipment of dynamic balancing, especially show the earlier period damage of bearing, shorten the maintenance week of equipment
Phase, increase the maintenance cost of equipment, affect product quality, aggravating working environment etc..
Content of the invention
In order to solve the problems, such as that above-mentioned prior art is difficult to overcome, the invention provides a kind of improved magnetic drive pump of structure, including 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, and outer magnet rotor 6 is pacified
It is contained in motor shaft end, separation sleeve 4 is set between interior magnet rotor 5 and outer magnet rotor 6, separation sleeve 4 is fixedly connected with pump cover 3 body seal,
The described pump housing 1, pump cover 3 and separation sleeve 4 couple integral, composition closing pump chamber it is characterised in that: join between the pump housing 1 inwall and impeller 2
Close and taper roll bearing 8 is installed, pump shaft 7 passes through axial contact bearing 9 and radial contact bearing 10 supports 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, joins between impeller groove 11 and pump housing groove 12
Close and taper roll bearing 8 is installed.
The invention has the beneficial effects as follows: magnetic drive pump pump shaft 7 and impeller 2 pass through taper roll bearing 8, axial contact bearing 9 and radial direction in pump chamber
Contact bearing 10 supports to be installed, and the magnetic drive pump of this structure can be bad with the dynamic balancing of effective control impeller 2, effective control pump shaft 7 and impeller 2
Axial float, increases magnetic drive pump useful life longevity, improves magnetic drive pump operational reliability and security.
