Abstract:In industrial production, automatic air pressure machine and the automatic speed played a huge role and real benefits Based on the current design of the companies buying pressure on manually operated machines, inefficient and high-intensity work, and unable to control whether a product passes, the whole Clutch have affected the quality. So the pressure for improvements, improvements have enabled powder Wai bearings pressed into the shell cover, and ensure that the pressure within the indentation, greatly increase the efficiency of its work, the most important is to ensure that the bond strength at the set point, ensuring the reliability of the product. PLC have in the 20th century the 1960s, after decades of development, has become a microprocessor to the core, integrated microelectronics technology, automation technology, network communications technology in the integration of common industrial control devices. Its high reliability, easy to use, high performance-cost ratio. On a worldwide scale, PLC is the largest, most extensive scope of application of automation products, can be said to be the most practical automation products. The design of the PLC in the electrical control of an application, because the PLC to automatically have a lot of strengths, The system will greatly simplify the hardware and the volume was reduced, and PLC anti-interference capability, high reliability, operation and maintenance simple.
