Sanpin speed converter in the paper drag system
1、The original system, the situation The original paper mill production line three simultaneous press, four dollars Dagang 7 synchronous speed of the original use of a motor speed through the belt drag, 1 rolls of paper machine motor speed alone, can produce 200 grams of Paper。 2、Frequency synchronization system: Sanpin synchronization through the use of frequency converter controller for the original system, a press Dagang and a 11KW motor with frequency allocation 15KW, 2, 3 and the press two, three, four-cylinder motor 7.5KW the configuration of the frequency 7.5KW. 11KW machine rolls 15KW motor configuration of the frequency increase braking and braking resistor module。 Synchronizer selection of Shanghai KMD08B-8 production output synchronous motor controller and the other configuration potentiometer (0-10V) for the use of fine-tuning。 3、Debugging process ⑴Stand-alone debugger Synchronizer to 8-output ratio coefficient of 1.00 set, the display board inverter motor home for the speed show that the potentiometer to 0, tachometer-conditioning, tachometer showed that the use of frequency converter with the same speed show。 ⑵Commissioning is expected to vote on-line a、The first unit controller output that is used to control the main motor of a machine press, the first unit output coefficient ratio should be maintained at 1.00, and the remaining proportion coefficient approach as close as possible to 1.00, while the use of potentiometers placed in the middle position, such as Coefficient of a larger proportion of bias can be adjusted pulley。 b、Each of the input-output made possible by the factory settings changed to 9 in the first way to eighth in the order are: 9,1,2,3,4,5,6,7, this could be revised if the effect was not obvious to all of the resumption of the original factory Set 9。 c、Production of 100 grams of paper, the host speed of about 40 Hz, 200 grams of the production of paper, the host speed is about 35 Hz, low-frequency as a result of Sasser have enough dynamic stability in the adjustment of 35 Hz when the operation is relatively stable, the economy。 d、Synchronous transfer out of sync when caused by paper cut, an appropriate adjustment can be a single converter and deceleration time, to extend the time synchronization track to avoid the governor when the shocks, the original installation reducer inconsistent with the direction of transmission will reducer Drive to amend the direction of unity。 e、Synchronous controller to alleviate 0 ~ 10V voltage start time for gentle deceleration 10 ~ 0V time for 10 seconds to set the factory was revised to 5 seconds。 f、In accordance with the frequency converter and motor away from the near and far, the biggest adjustment of output voltage inverter Pr001, with a 5V adjustment unit。 4、Determine the parameters for debugging: Pr001=380—395 Pr003=40 Pr012=10±1 Pr013=10 Pr032=1(或0) Pr033=1 Pr034=1 Pr035=4(15KW) Pr037=0 Pr043=4.0 Pr051=04 5、Rolls of paper machine debugging According to the performance requirements for the brake in time of 2.5 seconds, the use of skilled operators, the release paper machine to send gate in a timely manner, the brake is set at 6 seconds time is appropriate, to avoid another operation at 0:00 potentiometer, the converter is still out, Easy to run into trouble, the minimum frequency will be increased to 1.0, parking must be used to determine the stop button to stop the output inverter。 Determine the parameters: Pr012=15 Pr013=6 Pr009=1.0 Pr121=180 Pr123=180 Pr140=15 Pr142=0.1
