环形接力器是近代水轮机导水机构或者进水闸门上常采用的一种操作机构。其优点是结构紧凑、布置美观。但环形活塞加工困难,而影响产品质量,因此东方电机厂制造了环形活塞加工设备。本文介绍了该设备的工作原理、结构以及环形活塞加工工艺等。 Torque relay is a kind of operating mechanism commonly used in modern hydraulic turbine water guiding mechanism or inlet gate. Its advantages are compact structure, beautiful layout. However, the piston ring processing difficulties, which affect the quality of products, so Dongfang Electric Works manufacturing piston ring processing equipment. This article describes the working principle of the device, structure and ring piston processing technology.
