Tongxiang is a professional belt conveyor idler roller manufacturer.With the development of mining industry and the continuous improvement of the coal market in China, it has emerged a number of large-scale mines in recent years. The large and long belt conveyors continue to appear in these large mines, due to the large long belt conveyor load, conveyor belt length, the start performance of the entire belt conveyor, tension control, along the line The requirements for protection are high. The analysis of the selection and control principle of the belt conveyor control system which is now carried out.Good quality belt conveyor idler roller is very important.
The main technical parameters of the belt conveyor drive the drum diameter D=1000,500t/h; conveyor belt strength a = 2kN/mm; installation power N=3x800kW, power ratio= 1:1: 1. The driving mode adopts two driving points: nose and tail, that is, a main motor of the nose and a main motor at the tail. Reasoning analysis.The characteristic of the control system is that it can be applied to a variety of control tasks. It has good performance, high reliability, strong applicability and strong expansibility. It can flexibly compose different control modes through software programming and can realize complex logic control.Belt Conveyor Control utilizes this feature. The components of the control system are connected by bus-type plug-in connectors.

The installation and maintenance work is very convenient. Good quality belt conveyor idler roller is very important.Even in a poor underground working face environment, maintenance personnel and installers can accurately and quickly install the entire system. replace. The system itself has an independent voice communication system, which makes it possible to carry out voice communication in any place where the line extends, which facilitates the exchange of information between maintenance personnel and facilitates the installation and maintenance work. The safety protection circuit of the system itself is connected with the control circuit to ensure the safety and reliability of the system control.The system consists of three PROMOS control systems and one well monitor. The three main controllers of the control system are located at the head, middle and tail of the belt conveyor. Each set controls 2200m conveyor belts. The monitoring room of the underground mechanical and electrical team, each control system is equipped with: smoke, deviation, speed, longitudinal tear, coal, main motor temperature, over-temperature sprinkler and other protection, and there is a pull-wire emergency stop switch every 100 m There is a loud-speaking telephone every 200 meters for communication along the line.Good quality belt conveyor idler roller is very important. The three main control systems for the underground wells and the monitor on the wells are connected by a Linie bus to form a large system.Control principle After the system is powered on, the main controller first initializes the entire control system:The main controller performs inspection of non-intelligent components, mainly to determine the number and status of non-intelligent components of the entire system, and to determine the safety loop. Specific status and record.The main controller initializes the intelligent components, mainly according to the user program to set the input and output interfaces of the intelligent components, to determine that each should pay attention to the definition and use of the input and output interfaces of the main controller and intelligent components must be consistent.The communication method between the controller and each component is a report type. When the controller completes the above initialization process, it enters the waiting state. If the status of a certain component changes, it sends its own message to the controller in the form of a message, and the controller then issues a corresponding control instruction through the communication method. Ensure the system’s reaction speed and response time.
