Then, how does the frequency converter work on the leather mechanical slitter and complete its function? The following will be discussed in detail:
The working principle of the inverter in the system constant tension control The essence of the constant tension control in the retracting and unwinding process is to know the change of the winding diameter of the load during the operation, because the change causes the output torque of the motor to be maintained in order to maintain the operation of the load. Follow the changes in the diameter of the coil. Anbang letter frequency converter can do torque control, so it can also complete the constant tension control. Anbang letter frequency converter provides three analog input ports. The three-way analog input can be defined as a variety of functions, so one can be used as a torque reference and the other as a speed limit. For the slitter, the part of calculating the roll diameter is calculated by the tension controller. In other words, you can set the tension on the man-machine or text, calculate the roll diameter through the PLC, you can calculate the torque required to output the motor, through the analog output to the torque of the Ampang inverter given end can.
System debugging process and parameter setting 1. Parameter setting of Ampon Inverter (1) All parameters of the driver are adjusted to the factory value.
(2) Separate the motor shaft from the load.
(3) Set the motor rated voltage parameter setting 01-02, motor rated frequency parameter to 01-01.
(4) Set parameter 05-00 to 1 and press the KeypadRUN command.
(5) After the execution, check whether some of the parameters have been automatically filled in with the measured data.
2. Anbang letter converter closed-loop vector operation debugging will set the operation mode as panel start, the frequency given mode is given by the panel. Running mode is V/F+PG. Set the frequency to 10Hz, and then run. Observe whether the inverter will report the PG alarm. If the PG alarm is reported, set 10-01 to 1, and then turn off the power again. Press the Run button again to ensure that the inverter does not alarm. Press the Mode key at the same time to switch the display operating frequency. Observe whether the fluctuation occurs at 10Hz to ensure the commissioning is completed.
PVC Self-Repair High Speed Zipper Door
Zipper quick door
The curtain of the high-speed zipper door is made of 1.2MM PVC coating cloth which can be embedded into the window. The unique design of this zipper door makes it possible to provide efficient goods entrance and exit under the premise of minimizing heat loss, so as to maintain the original temperature conditions in the room. The high-speed zipper door can provide different opening and closing speeds. According to the different needs of customers to provide the best speed of adaptation. The high speed zipper door curtain section ensures the safety of equipment and personnel without any solid parts. The high speed zipper door has a self-repair function, which means that even if the curtain is derailed in the middle (e.g., hit by a forklift), The self-healing system will automatically guide the curtain rerail in the next loop.) We can do this in the event that the front or back of the door hits the curtain and derails.
The new zipper is professional for derailed repair zipper door, zipper head material nylon 66, with built-in steel wire rope and screws fixed curtain, under the impact of gravity can let the curtain out of the rapid and correct return to the track, and track teeth without damage, durable, improve the original zipper teeth easy to wear defects.
