I. Overview of YZ Submerged Slurry Pumps

The YZ submersible slurry pump features a vertical single-stage single-suction cantilever centrifugal pump design. The impeller is a semi-open impeller, equipped with agitator blades at the extension of the impeller's suction side.

Primarily used for suction of thick liquids, heavy oils, oil sludge, polluted liquids, mud, slurry, flowing sand, and flowing sludge in urban drainage ditches in industries such as environmental protection, municipal engineering, thermal power plants, coal gasification plants, oil refineries, steel mills, mining, papermaking, cement plants, food factories, and dyeing and printing, as well as fluids containing mud, sand, and debris and corrosive liquids.

Section 3: YZ Submerged Slurry Pump Structural Description

The YZ type pump is a single-stage, single-suction, cantilever structure, with the hydraulic components connected by bearing seats, support seats, and connecting pipes. The liquid is discharged through the discharge pipe components. The pump impeller is a semi-open impeller, with agitator blades at the extension of the impeller blade inlet. The main feature of this pump is that the pump shaft in the submerged section has sufficient rigidity, and there are no bearings or shaft seals between the impeller and the pump casing, allowing it to transport media containing high concentrations of solid particles. The pump can be inserted into the liquid at lengths between 800-2000mm, and an intake pipe can be provided upon request. The shaft seal is designed for larger pumps to operate submerged without a seal. The drive is by a vertical motor mounted on the motor support and the support seat, connected to the pump via a coupling.

4. YZ Submerged Slurry Pump Assembly Sequence

(1) Place the bearings individually in the bearing box and on the bearing housing.

(2) Install felt washers on the bearing end cover A, C, and the bearing box.

(3) Install bearing end covers B and C onto the bearing housing and secure them with bolts.

(4) Mount the bearing box with installed bearings onto the shaft, tighten the round nut, and securely fasten the bearing end cover A to the bearing box.

(5) Insert the shaft into the bearing housing, secure with bolts, tighten the adjustment screw, and mount the bearing on the support bracket. Fit the water shield at the appropriate position below the bearing.

(6) Secure the connecting pipe to the bearing housing, install the pump cover below the connecting pipe, fit and tighten the impeller at the bottom of the shaft, then sequentially install the pump body front cover and bolt it down. Adjust the gap between the impeller and the front cover using the adjusting screw at the bearing box (keep it between 1-1.5mm), and after adjusting, secure it with nuts and bolts.

(7) The motor support is mounted on the bearing housing and secured with bolts. The coupling component is installed at the top of the shaft, and the motor coupling is fastened to the motor shaft end with set screws. The motor is then mounted on the motor support and secured with bolts and nuts.

(8) Assemble the asbestos washers, liquid outlet elbows, and liquid outlet fittings in the order of the pump's output, and securely fasten them to the support bracket.
