1、 Overview of YZ Submerged Slurry Pump

The YZ submersible slurry pump is a vertical single-stage single suction cantilever centrifugal pump structure, with a semi open impeller and stirring blades extending from the suction edge of the impeller.
Mainly used in industries such as environmental protection, municipal engineering, thermal power plants, gas coking plants, refineries, steel mills, mining, paper industry, cement plants, food factories, printing and dyeing to extract concentrated liquids, heavy oils, oil residues, polluted liquids, mud, mortar, flowing sand, and mobile sludge from urban sewage channels, as well as fluids containing mud and sand residues and corrosive liquids.

3、 Structural Description of YZ Submerged Slurry Pump

The YZ type pump is a single-stage, single suction cantilever structure, connected to the hydraulic components of the pump with 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 stirring blades at the inlet extension of the impeller blades. The main feature of this pump is that the pump shaft in the underwater part has sufficient rigidity. There are no bearings or shaft seals between the impeller and pump casing, and it can transport media containing high concentrations of fixed particles. The length of the pump inserted into the liquid is between 800-2000, and it can be equipped with a suction pipe if necessary. The shaft seal adopts a larger pump inserted into the liquid for operation, without a shaft seal. The transmission is installed on the motor support and support seat by a vertical motor, and connected to the pump with a coupling.

4、 Assembly sequence of YZ submersible slurry pump

(1) Install the bearings separately on the bearing box and bearing seat.
(2) Install the felt ring onto the bearing end caps A, C, and bearing box.
(3) Install bearing end caps B and C onto the bearing seat and tighten them with bolts.
(4) Thread the bearing box with the installed bearings onto the shaft, tighten the round nut, and fasten the bearing end cover A onto the bearing box.
(5) Install the shaft into the bearing seat, fix it with bolts, tighten the adjustment screw, and install the bearing on the support seat. Place the water blocking ring in the appropriate position at the lower bearing.
(6) Fix the connecting pipe on the bearing seat and install the pump cover at the lower part of the connecting pipe. Install the impeller at the lower part of the shaft and tighten it. Install the pump body front cover in sequence and fix it with bolts. Use the adjustment screw at the bearing box to adjust the gap between the impeller and the front cover (controlled within 1-1.5mm). After adjustment, tighten it with nuts and bolts.
(7) The motor support is installed on the bearing seat and fastened with bolts. A coupling component is installed at the upper end of the shaft, and the motor coupling is fastened to the motor shaft head with fastening screws. The motor is installed on the motor support and fastened with bolts and nuts.
(8) Install the asbestos pad, outlet elbow, and outlet pipe fittings in the production sequence of the pump, and fix them on the support seat.
