Submersible pumps are usually used in low-pressure straight-through pipelines. The sealing performance depends entirely on the fit between the plug and the plug body. The compression of the sealing surface is achieved by tightening the lower nut. When assembling the submersible pump, first install the bearing on the bearing box and the bearing seat respectively, and install the felt ring on the bearing end cover A, C and the bearing box. Then install the bearing end caps B and C on the bearing seat and fasten them with bolts. Put the bearing box of the installed bearing on the shaft, screw the round nut, and fasten the bearing end cover on the bearing box.

The submerged pump is used to convey liquids that do not contain suspended solid particles and are easy to crystallize. The submerged pump is suitable for chemical, petrochemical, smelting, dyes, pesticides, pharmaceuticals, dilute graphics, fertilizers and other industries. Ideal equipment for acid corrosive media. In recent years, the application range of submersible pumps has been continuously expanded, and oil-sealed submersible pumps with forced lubrication have appeared. Due to the forced lubrication, an oil film is formed between the sealing surface of the plug and the plug body. In this way, the sealing performance is better, the opening and closing is labor-saving, and the sealing surface is prevented from being damaged.
