Thrust structure of high-power magnetic drive pump

Abstract

The invention relates to an axial balanced structure of a magnetic drive pump, and in particular relates to an axial force balanced structure of a high-power magnetic pump, belonging to the field of fluid machinery and fluid power engineering. The thrust structure of the high-power magnetic drive pump provided by the invention comprises a thrust static ring, a thrust moving ring, a fifth screw and a base plate, wherein one end of the thrust static ring props against a bearing bush; the other end of the thrust static ring props against a second bearing cap; the bearing bush and the thrust static ring are pressed and positioned by the second bearing cap by virtue of the fifth screw; one end, which props against the second bearing cap, of the thrust static ring is longer than the rear end face of a bearing base seat; a shaft sleeve is pressed and positioned by the shoulder part of a shaft and the thrust moving ring installed into the base seat; and the thrust static ring and the thrust moving ring form an axial friction pair. By utilizing the thrust structure provided by the invention, the service life of a transmission component is ensured, the reliability is greatly strengthened, the overhaul period of a pump is prolonged, and the maintenance cost is reduced.

Description

technical field [0001] The invention relates to an axial balance structure of a magnetic force pump, in particular to an axial force balance structure of a high-power magnetic force pump, and belongs to the field of fluid machinery and fluid power engineering. Background technique [0002] Magnetic drive is a new technology that uses the basic theory of modern magnetism to apply the magnetic force generated by permanent magnet materials or electromagnets to realize force or contactless transmission. The fundamental difference between magnetic drive and mechanical drive is that when it transmits torque to the transmission parts, the power transmission shaft in contact with the medium does not communicate with the outside world, but uses the magnetic field to transmit the torque through the working gap of the magnetic circuit or the thin wall of the isolation sleeve. moment. [0003] The internal transmission structure of the magnetic pump mostly uses sliding bearings, such a...
