Abstract

The invention discloses a manufacturing process of a magnet rotor in a magnetic pump. The manufacturing process comprises the following steps that a, a welding tool for the magnet rotor in the magnetic pump is made; b, a magnetic flow coil, multiple magnetic patches and a cushion block are mounted on a rotor base, and a sheath baffle, a sheath and the rotor base are connected in a spot welding mode to form a workblank of the magnet rotor in the magnetic pump; c, the workblank of the magnet rotor in the magnetic pump is taken up and placed on the welding tool for the magnet rotor in the magnetic pump; d, the sheath baffle is welded to the rotor base, the left end and the right end of the sheath are welded to the rotor base and the sheath baffle respectively, and then a semi-finished piece of the magnet rotor in the magnetic pump is made; e, the semi-finished piece of the magnet rotor in the magnetic pump is machined, and a finished piece of the magnet rotor in the magnetic pump is obtained if the machined piece passes inspection. In this way, the manufacturing process of the magnet rotor in the magnetic pump has the advantages that no splashing occurs in the welding process, welding quality can be guaranteed, product scrapping caused by internal stress is also eliminated, the product percent of pass is increased, and manufacturing cost is lowered.

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...
