Mechanism characteristics and usage advantages of underwater slurry pump

Submerged slurry pumps are mostly used in oil drilling mud solid control systems, which can pump thick liquids, heavy oil, oil residue, dirty liquids, mud, as well as fluids containing mud, sand, and corrosive liquids.

Submerged slurry pumps are mostly used in oil drilling mud solid control systems, which can pump thick liquids, heavy oil, oil residue, dirty liquids, mud, as well as fluids containing mud, sand, and corrosive liquids. The submerged slurry pump has significant advantages such as high efficiency, maintenance free, high temperature resistance, and long service life.
The submerged slurry pump is a vertical single stage single suction cantilever centrifugal pump structure. The impeller is a semi open impeller with a stirring impeller located at the extension of the suction side of the impeller. The vertical motor is installed on the motor base and connected to the pump through a coupling. The pump shaft in the submerged part has sufficient stiffness, and there are no bearings or shaft seals between the impeller and pump body. It can transport media containing high concentrations of solid particles. The length of the pump inserted into the liquid is between 800mm and 2500mm. If necessary, a suction pipe can be equipped. The main characteristics of the submerged slurry pump are that the pump shaft in the submerged part has sufficient stiffness, and there are no bearings or shaft seals between the impeller and pump casing, which can transport media containing high concentrations of solid particles; Maintenance free and high temperature resistant. The length of the pump inserted into the liquid is between 800-1900mm, and it can be equipped with a suction pipe if necessary. The transmission is installed by a vertical motor on the motor base and connected to the pump through a coupling. From the direction of the electric motor, the pump rotates clockwise. The flow passage components of this series of pumps are cast with high hardness alloy, which has high wear resistance, corrosion resistance, and impact resistance, thereby improving their service life. In addition, this series of pumps adopts power pressure reduction to ensure that the slurry is not easily leaked.
The underwater slurry pump is a single stage, single suction cantilever structure, connected to the hydraulic components of the pump by bearing seats, support seats, and connecting pipes. The liquid is discharged from the outlet pipe components. The impeller of the pump is a semi open impeller, and there are mixing blades at the extension of the impeller blade inlet. The main feature of this pump is that the pump shaft in the underwater part has sufficient stiffness, and there is no bearing between the impeller and pump casing, and no shaft seal is used, It can transport media containing high concentrations of fixed particles. The length of the pump inserted into the liquid is between 800 and 2000, and if necessary, it can be equipped with a suction pipe. The shaft seal is operated by inserting a larger pump into the liquid without a shaft seal. The transmission is installed by a vertical motor on the motor support and support seat, and connected to the pump through a coupling.
The YZ type submerged slurry pump, SP type submerged slurry pump, and ZJL type submerged slurry pump are vertical single stage single suction cantilever centrifugal pump structures. The impeller is a semi open impeller, and there are mixing blades at the extension of the impeller suction edge. It is mainly used in industries such as environmental protection, municipal engineering, thermal power plants, gas coking plants, refineries, steel mills, mining, paper making, cement factories, food factories, printing and dyeing to extract thick liquids, heavy oil, oil residue, dirty liquid, mud, mortar, quicksand, and flowing sludge from urban sewage channels, as well as fluids containing mud and sand residue and corrosive liquids.
