隔膜泵大型曲轴钢锭分体制造工艺的探讨

Discussion on the Ingot Manufacturing Technology of Diaphragm Pump Large Crankshaft

DGMB系列隔膜泵为三缸单作用往复式活塞隔膜泵,曲轴是隔膜泵的重要部件。为满足远距离固—液两相介质长距离管道化料浆输送,曲轴的规格向着大规格、多拐数发展。传统的曲轴机械加工方法金属材料利用率低下,加工周期长等因素已经制约了隔膜泵向着现代化、大型化、高效率发展的步伐,本文通过采用钢锭分体制造工艺,将曲轴中曲拐与轴分体制造,为曲轴制造开辟了一条新路。

DGMB series diaphragm pump is the three cylinder single acting reciprocating piston diaphragm pump, the crankshaft is an important part of the diaphragm pump. Specifications of large size and multi-turn numbers for crankshafts would be developed as a trend to meet long distance pipeline transportation- with solid-liquid material. Low metal material utilization and long processing cycle with traditional crankshaft machining method has restricted the development of the modernization, large-scale and high efficiency. By using the ingot manufacturing process, crank and shaft are made separately in this paper, which ciency. By using the ingot manufacturing process, crank and shaft are made separately in this paper, which open up a new way for crankshaft manufacturing.
