Mine frequency conversion winch is the main equipment to facilitate personnel and materials in mine work. The development process of the electronic control system of variable frequency mine hoist should be developed towards the new equipment of unattended, networking, remote control and full automation.

The electric control features of mine variable frequency winch are as follows:

1. Through the network platform, the frequency converter can realize the automatic data exchange, with the function of automatic adjustment of operating parameters, and has good dynamic follow-up of master and slave motors to ensure the power balance of multiple motors.

2. The system has the function of fault monitoring and reliable fault alarm protection. With over-voltage, over-current, under voltage, short-circuit, grounding, overheating and other protection functions.

3. It has the function of low speed belt inspection. 2 m / S ~ ve rated speed adjustable.

4. FX2N PLC is used as the main control device. It is designed and manufactured according to the requirements of GB / T17626 electromagnetic compatibility standard.

5. Because the control system is controlled by PLC, it is easy to realize the locking control of the main belt conveyor and the front and rear equipment.

6. Through real-time detection of the speed of the conveyor, the main control console controls the brake action at zero speed of the conveyor and automatically holds the brake, thus avoiding the over-current of the conveyor's car sliding, frequency converter and motor.

7. The frequency converter is used to complete the starting and speed regulation of the motor, which can realize the smooth start and speed regulation requirements of the belt conveyor, and has obvious energy-saving effect under the condition of long-time low-speed operation (such as transporting people, inspecting rope and checking belt).

The above is the characteristics of mine inverter winch electric control, if you want to know other information, you can contact our online customer service.
