Abstract

The invention discloses an impeller installation tool, which comprises a fixed sleeve, a lead screw, a transition sleeve and a top block; The transition sleeve, the connector at the closed end of the fixed sleeve are screwed into the threaded hole at the front end of the pump shaft; the top block is inserted into the long guide hole on the side wall of the fixed sleeve, The front end is threadedly connected to the opening end of the fixing sleeve. The installation tool of the invention is simple in structure, convenient in disassembly and assembly, and convenient in positioning operation; the force on the impeller during the installation process is even, avoiding damage to parts, and has good safety.

Description

technical field [0001] The invention relates to an impeller installation tool, which belongs to the field of impeller assembly. Background technique [0002] When assembling the impeller, it is necessary to align the impeller shaft hole with the impeller position of the pump shaft first, and then ensure that the keyway of the shaft hole is aligned with the key on the pump shaft, but the clearance between the pump shaft and the inner hole of the impeller, the keyway and the key is usually only There are 0.05mm. During installation, if there is a slight assembly deflection, the impeller will contact the shaft, the key and the keyway, and the friction generated by the contact surface will make it impossible to install manually, so it needs to be installed by external force. [0003] One of the commonly used methods is to use a crane to hang the impeller, move the crane in the direction of impeller installation, and use the crane to pull it in. The second is to use a hand hamm...
