Problems solved by technology

Due to the existence of the magnetic block, spatter will be generated during welding, which will affect the welding quality. In addition, due to internal stress factors, defects will be formed after cooling, which cannot be remedied, the scrap rate is high, and the production cost is high.

Abstract

The invention discloses a manufacturing process of an inner magnetic rotor of a magnetic force pump. The steps are as follows: a. Manufacturing welding tooling for the inner magnetic rotor of a magnetic force pump; , and then spot-weld the sheath baffle, the sheath and the rotor seat to form the inner magnetic rotor blank of the magnetic pump; c, pick up the inner magnetic rotor blank of the magnetic pump and place it on the welding tooling of the inner magnetic rotor of the magnetic pump; d, Weld the cover baffle with the rotor seat, and weld the left and right ends of the cover with the rotor seat and the cover baffle respectively to make a semi-finished part of the inner magnetic rotor of the magnetic pump; e. Machine the semi-finished part of the inner magnetic rotor of the magnetic pump After processing and passing the inspection, the finished magnetic rotor in the magnetic pump is obtained. The manufacturing process of the magnetic rotor in the magnetic pump of the present invention adopts such a method that spatter does not occur during welding, which can ensure welding quality, eliminate product scrapping caused by internal stress, improve product qualification rate, and reduce manufacturing cost.

Description

technical field [0001] The invention relates to a pump, in particular to a manufacturing process of a magnetic rotor in a magnetic pump. Background technique [0002] The magnetic pump is composed of a pump, a magnetic driver and a motor. The magnetic driver includes an inner magnetic rotor, an outer magnetic rotor and an isolation sleeve. When the motor drives the outer magnetic rotor to rotate, the magnetic field can penetrate the air gap and non-magnetic materials, and drive the impeller to rotate. The connected internal magnetic rotors rotate synchronously to realize the non-contact transmission of power, thereby pumping liquid. Such as image 3 As shown, the magnetic rotor in the magnetic pump includes a rotor base 15, a magnetic flux coil 20, a plurality of magnetic blocks 17, a spacer 18, a cover 16 and a cover baffle 19, the rotor base 15 has a shaft hole, and the middle part of the rotor base 15 There is a magnetic flux circle 20, and a plurality of magnetic blocks...
