Study on the Trial-Manufacture of a Large Discharge Emulsification Pump's Crankshaft
Aimed at the work condition and structure's characteristics of a large discharge emulsification pump's crankshaft, the load type of a low rotational speed and high load were determined, and the quality of a crankshaft is related with material, manufacture, heat treatment and so on. Based on unit production model during the research and development, the processes of the roughcast, manufacture and heat treatment were described: The roughcast was forged by a forging die in order to suffice a low rotational speed and high load. The crankshaft was manufactured by a universal machine tool, clamps and measuring tools in order to obtain the precision of specification after processing. Heat refining after rough cutting, nitrogen treatment and polishing after finish machining were selected in order to improve mechanical property, application life and cost reduction.
