Mixed-flow pump with clutch protection structure

Abstract

The invention discloses a mixed-flow pump with a clutch protection structure. The mixed-flow pump with the clutch protection structure comprises a base and a motor; a pump body shell is fixedly installed on the base, a rotation shaft is inserted into the middle of the right side of the pump body shell, an impeller base is fixedly welded to one end of the rotation shaft, an impeller shaft is fixedly welded to the middle of the other side of the impeller base, and impeller blades are evenly inserted into the outer side of the impeller shaft; and the outer side of the other end of the rotation shaft is sleeved with a connecting sleeve, a first transmission shaft is fixedly welded to the other end of the connecting sleeve, an adjusting sleeve is fixed to the outer side of the first transmission shaft through a bearing, and the outer side of the adjusting sleeve is sleeved with a clutch shell. According to the mixed-flow pump with the clutch protection structure, transmission is achieved through rough friction connection between a friction disc and a drive disc, when the interior of the pump body shell is jammed, the drive disc can overcome the friction force at the joint of the drive disc and the friction disc to slowly rotate, the pump body damage degree is effectively reduced, motor burnout is prevented, and the working safety of the device is improved.

Description

technical field [0001] The invention relates to the field of mixed-flow pump equipment, in particular to a mixed-flow pump with a clutch protection structure. Background technique [0002] Mixed flow pump is a kind of pump between centrifugal pump and axial flow pump. When the prime mover drives the impeller to rotate, it acts on the liquid with both centrifugal force and axial thrust. It is a combination of centrifugal pump and axial flow pump. Oblique outflow impeller, which is mainly used to convey clean and polluted media, chemically neutral or aggressive media. [0003] Most of the impellers of existing mixed flow pumps are integrally cast, and the impellers are installed inside the pump casing. If a single impeller blade is accidentally damaged, the entire impeller needs to be replaced, which greatly reduces the maintenance cost of the mixed flow pump and leads to waste of resources; [0004] In addition, the power transmission device of the existing mixed-flow pump i...

Problems solved by technology

[0005] Purpose of the invention: The purpose of the present invention is to provide a mixed-flow pump with a clutch protection structure to solve the problem that the impeller of the current mixed-flow pump proposed in the above-mentioned background technology is integrally cast, resulting in the need for the entire replacement during maintenance and replacement, serious waste, and mixed-flow problems. If the pump is stuck while working, the power output will not be cut off in time, which will easily deepen the damage in the pump and cause the motor to burn out.
