The circuit structure is simple and the reliability is high. The sizing tank, the sizing tank and the drying cylinder are driven by an AC variable frequency motor, while the weaving shaft and the towing roller are driven by an AC reed wire manufacturer servo variable frequency motor. This kind of motor is mainly used in textile machines with low speed regulation accuracy and small speed regulation range.
The movement of each mechanism is controlled according to the production process curve, thereby simplifying the mechanism. As for the spinning frame, since the forming cam in the forming mechanism is removed by using a frequency conversion governor, the phenomenon that the peach bottom is stopped and the peach top is shocked due to the forming cam is overcome. Industry application case download: Shanghai Shanyu inverter SY6000G textile machinery industry application.
The 12 air conditioners in the whole year could save more than 240,000 yuan of electricity, and the average unit consumption of air conditioners decreased by 6. At the same time, it also has good addition and subtraction characteristics, torque characteristics and current limiting characteristics. Photosensitive machine. The following highlights the roving frame sizing machine. The whole machine is controlled by industrial computer. The main terms are on machines with high precision and wide speed range. Including card opener, card, sliver, comber, draw frame, roving frame, spinning frame and Luo Jian machine. The other type is dedicated asynchronous motor for AC variable frequency speed regulation.
A total of 5 inverters, 2 servo controllers, and sensors such as pressure, temperature, and moisture regain are applied. However, the speed adjustment range is within the range of 10: 1, the speed adjustment accuracy is lower by 2% to 5%, and the low speed performance is not ideal. 2. It is suitable for slitting warping machines, sizing machines, heat setting machines, and chemical fiber filament spinning equipment with high speed regulation and constant tension and constant line speed. GA308 sizing machine This sizing machine is AC distributed transmission.

The main electrical system structure and working principle of the rotor spinning machine are as follows: The power transmission process of the system shown in the figure above is as follows: 的 The three-phase asynchronous motor powered by the power grid drives the synchronous engine through a belt, and the synchronous generator issues a three-phase voltage of about 280V The voltage is changed to 70V by a three-phase intermediate frequency transformer, and then supplied to a three-phase miniature spinning cup motor.
It is easy to debug, but the problem is also obvious: 1. The problem of data transmission is because the information of each device of B, C, D, and E are all It must be transmitted to the engineering station and management network through the A device, so the data of the B, C, D, and E devices to the engineering station is poor in real-time. As an operator station, TP37 needs to communicate with A, C, and D at the same time. It also requires a long data update period. 2. Communication capability problems Because C and D devices use CPU314 and CPU315-2DP in S7-300 series PLCs, their number of S7 fixed connections is limited. For example, for C device, it must be connected to one A device and two D devices at the same time.
For the manual debugging of A, C, and D devices, a TP170B is used to connect PLCs nearby through the MPI network. The entire control system consists of a PROFIBUS network. The A device selects S7-400 series PLC, the CPU is CPU412-2DP, and is used as the PROFIBUS master station. Its own I / 0 is composed of ET200M; the C device and D device are selected as PROFIBUS slaves of A device by ET200M remote I / 0 mode ; B equipment and E equipment use S7-200 series PLC, and equipped with EM277, as the intelligent slave station of A equipment directly.
A The connection between the binding wire calculation and the engineer station and the network connection with the management layer are the same. The operator station also uses TP37. The manual debugging of A, C, D equipment is completed by using a TP170B nearby connection. For the first design scheme, the control system of each device is relatively independent and can be run or stopped independently.
