Abstract
The invention provides an axial force balancing mechanism of an internal magnetic rotor of a magnetic pump. Interception ring belts (5) are arranged on an inner ring face of a rotor ring (11) of the internal magnetic rotor and an external ring face of a sliding bearing sleeve (4) on a pump cover, so that a pressure (P1) of a medium entering to the front side of a wheel disc (12) of the internal magnetic rotor (1) is controlled; a backflow hole (6) is arranged on the wheel disc (12) of the internal magnetic rotor (1); and when the pressure of the medium at the front side of the wheel disc (12) of the internal magnetic rotor (1) is not equal to a pressure of the medium at the back side of the wheel disc (12), backflow balance is carried out through the backflow hole (6), and pressures of cavities at the front side and the back side of the rotor (1) are automatically adjusted to be equal. Therefore, an axial force generated by that the pressures at the front end and the back end of the internal magnetic rotor are not equal can be reduced and removed.
Description
Technical field
What the present invention relates to is magnetic drive pump, particularly makes the mechanism of magnet rotor axial force balance in magnetic drive pump.
Background technique
Magnetic drive pump is when running work, medium can enter into separation sleeve inner chamber and circulate, in the rotor ring of interior magnet rotor, outer ring surface respectively with separation sleeve and pump cover on plain bearing housing cover Spielpassung, forward end and the rear end side of the interior magnet rotor of medium in separation sleeve produce unequal pressure, simultaneously due to the forward end of interior magnet rotor and the stress surface of rear end side not etc., before interior magnet rotor, the rear end side poor effect that is stressed will make interior magnet rotor produce axial force, therefore the axial force that to whole rotor is has a significant impact, can affect smooth rotation and the working life of rotor system.
Summary of the invention
The object of the invention is to improve for the shortcoming deficiency of above-mentioned prior art, provide a kind of
magnet rotor axial force balance mechanism in magnetic drive pump, so that interior magnet rotor axial force balance improvessmooth rotation and the working life of rotor system.
The present invention
magnet rotor axial force balance mechanism in magnetic drive pumpinterior magnet rotor 1 is fixedly mounted on main shaft 2, the inside and outside anchor ring of the rotor ring 11 of interior magnet rotor respectively with separation sleeve 3 and pump cover on sliding bearing cover for seat 4 Spielpassung, it is characterized in that being provided with the endless belt 5 that dams between the inner ring surface of rotor ring 11 of interior magnet rotor and the outer ring surface of the sliding bearing cover for seat 4 on pump cover, dam the gap width of endless belt 5 according to the minimum running clearance standard of API610-2004, to control the pressure medium P1 of wheel disc 12 front sides that enter into interior magnet rotor 1; On the wheel disc 12 of interior magnet rotor 1, offer return port 6, return port 6 diameters
; The R--endless belt external diameter radius that dams, the r--endless belt internal diameter radius that dams, N gets 5-7, and n-return port quantity distributes and determines according to bulk.When the pressure P 1 of the wheel disc 12 front side media of interior magnet rotor 1 with and the pressure P 2 of wheel disc 12 rear side media unequal time, in the high chamber of pressure, medium can flow in the chamber that pressure is low by return port 6, thereby realize the pressure in self-regulating rotary 1 chamber, both sides, front and back, the pressure of both sides is equated, reach the axial force that reduces and eliminate interior magnet rotor generation.
The present invention is rational in infrastructure, manufactures easyly, has effectively reduced the axial force that interior magnet rotor 1 produces,
improvesmooth rotation and the working life of rotor system.
Accompanying drawing explanation
Fig. 1 is embodiment of the present invention structural representation.
