汽轮机预扭叶片装配试验平台设计与开发
|
摘要
针对汽轮机预扭叶片人力锤击装配效率低、体力耗费大、工伤频发等问题,基于Solid Works设计开发了一套预扭叶片装配试验平台,对叶片装配进行试验研究。通过电动十字滑台、力平衡系统、框架及承载架的设计与加工制造,实现了预扭叶片的省力、高效装配,提高了操作安全系数,并经现场试验验证了所设计试验平台的有效性。
Aiming at the problems of low assembly efficiency of human torsion of steam turbine pre-twisted blades,large physical effort, and frequent occurrence of work-related injuries, a set of pre-twisted blade assembly test platform is designed and developed based on Solid Works to conduct experimental research on blade assembly.Through the design and manufacture of the electric cross slide, force balance system, frame and carrier, the labor saving and efficient assembly of the pre-twisted blades is achieved, the safety factor for operation is improved, and the effectiveness of the designed test platform is verified by field tests.
