Description

Technical Field

[0001] The utility model relates to the technical field of chemical equipment maintenance, in particular to a welding tool for a shielding sleeve end plate in a shielding pump. Background Art

[0002] In the industrial production process of chemical industry and other industries, shielded pumps are widely used. Due to the thin wall thickness of the shielding sleeve, the shielding sleeves on the rotor and stator of the shielded pump are often damaged during operation. After the shielding sleeve is damaged, a new shielding sleeve needs to be made and then welded and installed on the rotor or stator. When making the shielding sleeve, it is first necessary to make a sleeve body with a sleeve structure, then put the sleeve body on the rotor or stator, and then weld the end plates to the two ends of the sleeve body; because the sleeve body is tightly fitted on the rotor or stator; and the thickness of the shielding sleeve and the end plate is very thin, the welding quality requirements are high, and the welding operation is more difficult.

[0003] In the prior art, after the rotor or stator is fixed, the weld between the sleeve and the end plate is manually welded by the operator. Due to the different skill levels of the operators, the welding techniques are different. In addition, the welding process cannot be completed continuously in one go, which will cause multiple welding joints in the weld, resulting in the inability to guarantee the welding quality. At the same time, during manual welding, the weld base material is heated unevenly, and there will be subtle base material unfused defects that cannot be detected by the naked eye. In addition, the weld width and thickness are small, generally the weld width is 0.5 mm and the thickness is 0.2 mm, and the weld cannot be inspected by filming. If there are weak points in the weld, the shielding sleeve will be damaged during use, which will cause equipment failure and directly shorten the equipment life cycle. Frequent maintenance of the equipment will affect normal production and generate large maintenance costs. There is also welding equipment that sets the rotor with the shielding sleeve vertically, drives the rotor to rotate through a motor, and then welds the rotating shielding sleeve through a welding gun. However, this welding equipment has a complex structure, which makes the up and down rotation of the shielding sleeve cumbersome and difficult, and the welding efficiency is low.
