If the metering pump motor is not started, the screw motor cannot be started to rotate forward. This is a protection program. It is to prevent the metering pump from being started, and the screw motor is directly started to feed materials. If the metering pump does not rotate for a long time, the pressure in front of the pump will be too high. This is a dangerous phenomenon, and the pressure may be too high. There is a risk of pipe bursting in the equipment.
所述报警压力的设定，是反应釜螺杆电机的前提，否则，反应釜螺杆电机正转无法启动，防止压力闭环控制的时候出现压力过大，在运行的过程中如果当前显示的压力超过了这个报警压力，反应釜螺杆电机将会立即停止工作。 The setting of the alarm pressure is the premise of the screw motor of the reactor. Otherwise, the screw motor of the reactor cannot be started in forward rotation, so as to prevent the pressure from being too high during the pressure closed-loop control. If the current displayed pressure exceeds the At this alarm pressure, the screw motor of the reactor will stop working immediately.
步骤3-1）启动计量泵电机的步骤包括： Step 3-1) The steps to start the metering pump motor include:
3-1-1）在系统传输总控制柜的触摸屏在触摸屏上设定计量泵电机的转速； 3-1-1) Set the speed of the metering pump motor on the touch screen of the system transmission master control cabinet;
3-1-2）PLC控制器将所设定的转速传递给变频器； 3-1-2) The PLC controller transmits the set speed to the inverter;
3-1-3）变频器拖动计量泵电机按所设定的转速转动。 3-1-3) The frequency converter drives the motor of the metering pump to rotate at the set speed.
第一牵伸浴槽中的水不循环，由PLC控制器控制其加热，第二牵伸浴槽中的水是与第二循环水箱中的水进行交换、循环。 The water in the first drawing bath does not circulate, and its heating is controlled by a PLC controller, and the water in the second drawing bath exchanges and circulates with the water in the second circulating water tank.
用于壳聚糖纤维湿法纺机器的电气控制系统设计合理，根据壳聚糖纤维湿法纺机器的特点布局系统元器件，并设有多重保护，安全性能好；纺丝工艺参数设定简单，无需研究人员进行计算，直接在触摸屏上设定预期所要的线速度或者转速即可；卷绕设备有双重卷绕，避免了退绕浪费的时间，同时减少了纤维的浪费。 The design of electrical control system for chitosan fiber wet spinning machine is reasonable, the components of the system are arranged according to the characteristics of chitosan fiber wet spinning machine, and multiple protections are provided, with good safety performance; the setting of spinning process parameters is simple , no need for researchers to calculate, just set the expected linear speed or rotational speed directly on the touch screen; the winding equipment has double winding, which avoids the time wasted in unwinding and reduces the waste of fibers.

The water pump installed in the washing water tank is adjusted by a frequency converter, and the constant temperature heating is controlled by the temperature controller.
本系统的传动部分也就是纤维的牵引部分（包括单辊、一号五辊、二号五辊、三号五辊、三层水洗辊、上油辊、轧水辊）都可通过触摸屏直接输入预定线速度，无需任何人工计算，节省研究人员的工作量和时间。 The transmission part of the system is also the traction part of the fiber (including single roller, No. 1 five-roller, No. 2 five-roller, No. 3 five-roller, three-layer washing roller, oiling roller, water rolling roller) can be input directly through the touch screen Predetermined line speed without any manual calculation, saving researchers' workload and time.
绕丝机即卷绕部分由两个绕丝头，一个横动，和一个计米器组成，两个绕丝头可独立控制工作，如果其中一个所设定的卷绕米数达到，可人工切换到另一个绕丝头上，用两个绕丝头省去了纤维退绕时间，减少纤维的浪费。同时用横动可以使纤维以一定的角度缠绕在绕丝头上，避免了纤维堆积缠绕的现象。 The winding part of the wire winding machine is composed of two winding heads, a traverse, and a meter counter. The two winding heads can be controlled independently. Switch to another winding head, using two winding heads saves the fiber unwinding time and reduces fiber waste. At the same time, traversing can make the fiber wind on the winding head at a certain angle, avoiding the phenomenon of fiber accumulation and winding.
水洗用水箱的控制、反应釜螺杆的正反转、恒压供料、恒温控制、计量泵计量供料和后续的传动设备都和系统传输总控制柜相连，如果在运行过程中出现故障，可以通过触摸屏（触摸做了报警记录画面）快速找到故障原因，缩短检修时间，减少原料浪费。 The control of the washing water tank, the forward and reverse rotation of the reactor screw, constant pressure feeding, constant temperature control, metering pump metering feeding and subsequent transmission equipment are all connected to the system transmission master control cabinet. If there is a failure during operation, it can be Quickly find the cause of the fault through the touch screen (touching the alarm record screen), shorten the maintenance time, and reduce the waste of raw materials.
综上所述，本实用新型系统可以使壳聚糖纤维湿法纺机器设备更智能，使用更方便，缩短研究周期，减少原料浪费，更有效的推进我国对“壳聚糖”纤维的研究。 In summary, the utility model system can make the chitosan fiber wet spinning machine equipment more intelligent, more convenient to use, shorten the research cycle, reduce the waste of raw materials, and more effectively promote the research on "chitosan" fiber in my country.
