Abstract

The invention provides a method for quickly disassembling a large-sized fan impeller. The method comprises the following specific steps of fixing an old steel winding coupler with a to-be-disassembled impeller by using a screw; uniformly welding reinforced steel plates on the surface of the old steel winding coupler; placing a jack between the old steel winding coupler and the to-be-disassembled impeller, and slowly jacking out the impeller by utilizing a telescopic joint of the jack. The method for quickly disassembling the large-sized fan impeller is simple, has a quick and safe disassembling function, can be applied to any type of fan impellers and is high in generalization; other parts cannot be damaged.

Description

technical field [0001] The invention belongs to the field of fan impeller disassembly, and in particular relates to a fast and safe disassembly method suitable for any large fan impeller. Background technique [0002] The desulfurization induced draft fan is one of the most important equipment in steel production. After a long time of use, it needs to be shut down for inspection, maintenance, disassembly of the impeller, and replacement of the bearing. The existing dismantling method is usually: fix bolts on both ends of a steel plate, then fix it with the impeller, and use a jack to push out the impeller. When this method is used for disassembly, the force on the impeller is uneven, the strength is not enough, and the disassembly is difficult. [0003] Therefore, developing a fast and safe disassembly method for the fan impeller is an urgent problem for those skilled in the art. Contents of the invention [0004] To solve the above problems, the present invention di...
