Description

Technical Field

[0001] The utility model relates to a vertical slurry pump hoisting device. Background Art

[0002] Vertical slurry pumps are mainly used in environmental protection, municipal engineering, thermal power plants, gas coking plants, refineries, steel mills, mining, papermaking, cement plants, food factories, printing and dyeing industries to pump concentrated liquids, thick oils, oil residues, dirty liquids, mud, mortar, quicksand and flowing sludge in urban sewage ditches, as well as fluids containing mud, sand and slag and corrosive liquids. Vertical slurry pumps are single-stage, single-suction cantilever structures. The hydraulic components of the pumps are connected by bearing seats, support seats and connecting pipes. The liquid is discharged from the liquid outlet pipe components. The pump impeller It is a semi-open impeller with a stirring blade at the extension of the impeller blade inlet. The main feature of this pump is that the pump shaft in the submerged part has sufficient rigidity. There is no bearing between the impeller and the pump casing, and no shaft seal is used. It can transport media containing fixed particles with a large concentration. The length of the pump inserted into the liquid is between 800 and 2000. If necessary, it can be equipped with a suction pipe. The shaft seal adopts a larger pump inserted into the liquid for operation. No shaft seal is provided. The transmission is driven by a vertical electric motor installed on the motor support and the support seat, and connected to the pump with a coupling.

[0003] A vertical slurry pump is a pump equipment used for mud transportation and the pump shaft is positioned perpendicular to the horizontal plane. A vertical slurry pump is generally composed of a pump casing, a motor, a coupling, a support seat and other structures. Due to the heavy weight of the slurry pump, a lifting device is usually used for lifting during installation. However, the slurry pump is prone to damage to the motor during the lifting process, which affects its service life. In addition, the slurry pump is not easy to fix quickly during lifting and needs to be tied and fixed with tools such as chains. Not only is it difficult to operate quickly, it also affects the safety of lifting. In addition, the slurry pump is prone to shaking during lifting, which affects the stability of the slurry pump during lifting. Utility Model Content
