在机械液压调速器中,缓冲器大致有三类:即预压缩弹簧式;从动活塞旋转式;液压放大式。缓冲器是调速器中的关键部件之一,它的任务是保证调节系统稳定,转速能恢复至额定值,调节过渡过程品质优良,提高调速器的灵敏度。液压放大式缓冲器是天津水控厂设计和制造的,已装配在XT型,T-100A型,ST-100A型调速器中。投入使用的一些调速器中,由 In the mechanical hydraulic governor, the buffer is roughly three categories: the pre-compression spring; driven piston rotary; hydraulic amplification. The buffer is one of the key components in the governor. Its task is to ensure that the regulating system is stable, the speed can be restored to the rated value, the quality of the transition process is adjusted, and the sensitivity of the governor is improved. Hydraulically amplified shock absorber is designed and manufactured by Tianjin Water Control Plant. It has been assembled in XT, T-100A and ST-100A governors. Some governors put into use, by
