The high level of garbage crane and the characteristics of the crane itself have brought great challenges to the stable and reliable operation of the system. Through the accumulation and summary of the operation characteristics of garbage in the grab bucket through the work in the crane industry, our company has developed a set of frequency conversion speed regulation control method designed for garbage crane, so that the garbage crane can run stably and reliably.
Each garbage crane has its own independent electrical control system, operation console and HMI display panel, according to the needs of users can provide manual, semi-automatic control system. Hand and automatic switching is convenient and fast.
1. The speed range is large: due to the characteristics of garbage grab and improve efficiency requirements, so that the system speed requirements are very large, our company can provide multi-level multi-gear speed and stepless speed selection according to the needs of users;
2. Smooth operation: use the torque output of the optimized motor to effectively control the acceleration and deceleration of the driving to avoid the grab bucket swaying, so as not only to make the system run smoothly, but also to provide a good measuring environment for the weighing system. The weighing system and the control system are designed to work together but independently, and a failure of one will not cause the other system to fail.
3. A variety of control methods and command methods: V/F control, vector open loop or vector closed loop control. In the special case of the user, we have a variety of command methods to choose from, there are potential poles, 2-4 master console, 0~10V or 4~20mA analog signals.
4. Convenient hand, automatic switching: through a simple setting, the system can run in the automatic state, providing automatic feeding, stacking and weighing functions, while providing self-protection, at the same time, as long as the operator has input, it can be restored to the manual state to ensure safety. Achieve "easy switching, manual priority".
