NOUFERROUS METALLURGICAL EQUIPMENT

Diaphragm pump is a “heart” equipment in the remote slurry transportation system. Especially in the long-distance pipeline transportation system of high abrasion and high concentration of solid-liquid two-phase medium, diaphragm pump is irreplaceable by others. Diaphragm pump is of simple structure, sturdy and durable, easy to operate, and most of the parts are easy to be fabricated; the power end is the part with most technological difficulties of the entire diaphragm pump, including relatively precise parts such as crankshafts, connecting rods, piston cylinders, crossheads, etc. Especially for crankshafts, it requires specific equipment to complete the processing. This paper discusses the structural transformation of the power end to reduce the difficulty of processing key parts, thereby reducing costs and improving efficiency.
