Moreover, this kind of pumping unit can be started in the condition of zero-load and run in the condition of full-balance. 该机整机结构简单、受力均匀、运行平稳、可靠性高,并能实现完全平衡和空载启动。
When the crane is in the zero-speed, zero-load, the self zero-tracking will act, and zero drift of the detecting system can be corrected. 设计了零速空载零位自辨识跟踪技术,消除了检测系统的零点漂移影响。
