Abstract

The invention relates to a detachable impeller head structure for a dredging pump, which belongs to the field of fluid machinery and fluid power engineering. The impeller head structure of the present invention includes a head body, a sealing ring, and a retaining ring; a stepped cylindrical head installation hole is processed at the front end of the impeller shaft hole; The inner shape of the hole is matched, the rear end of the side wall of the head body is provided with a retaining ring slot, and the front end of the head body is axially provided with a threaded blind hole for disassembly; the head body is installed on the head of the front end of the impeller shaft hole In the installation hole, the head body is axially limited relative to the impeller through a stepped cylindrical structure; Front axial limit; a sealing ring is installed in the sealing ring installation groove on the side wall of the head body.

Description

technical field [0001] The invention relates to a detachable impeller head structure for a dredging pump, which belongs to the field of fluid machinery and fluid power engineering. Background technique [0002] The dredging pump is the core equipment of the dredger in the dredging industry, and the working performance of the dredging system largely depends on the performance of the dredging pump. The dredge pump unit has a heavy load and a large driving power, generally above 2000kw, which has extremely high requirements on the stability of the unit’s operation. Among them, the dynamic balance performance of the rotating part impeller is the key factor affecting the operation stability of the unit. [0003] Due to the large size and weight of the dredge pump impeller, when performing dynamic balancing work, it is necessary to pass the balance mandrel through the impeller shaft hole and use both ends to support it. [0004] In the existing traditional technology, the dredge...
