The advantages of variable frequency winch are mainly reflected in four aspects, which affect its use frequency and industry.
① Reduce maintenance and repair costs.
The winch control system with frequency conversion control as the control core makes the winch control performance and protection performance more perfect;
Compared with the old electric control system, the failure rate of the equipment is reduced by more than 80%, the maintenance rate of the equipment is reduced by 50%, and the maintenance cost is reduced by more than 65% compared with the same period, which has great safety benefits.
② The energy saving effect is remarkable.
The winch control circuit adopts frequency control system, which has better energy saving effect compared with the original series resistance speed control system.
With vector control technology as the core, the variable frequency speed control system eliminates the input of the original winch series starting resistance, reduces the resistance reduction loss and saves the power loss of the equipment.
③ Improve security.
By adopting frequency conversion technology, the problem of poor reliability of the original electric control system is solved, the maintenance rate and accident rate of equipment operation are reduced, and the labor intensity of workers is reduced. Since its use, the winch has been running stably without any fault;
It improves the safety and reliability of the electric control system, saves the cost of equipment maintenance and ensures the safe operation of the winch.
④ Simple operation, only need simple forward and reverse control, automatic control speed of acceleration and deceleration points, reduce the labor intensity of operators.
