Remote Centralized Intelligent Liquid Supply System of Emulsion Pump in Fully-mechanized Mining Face
In order to better meet the emulsion requirements of 6301 working face,a remote centralized intelligent liquid supply system based on frequency conversion+power frequency control,optical fiber communication and monitoring technology was designed and applied in engineering.The remote centralized intelligent liquid supply system communicates with the central control center of crossheading through the optical fiber communication network to grasp the demand of face emulsion in real time,so as to respond in time;adopt variable frequency emulsion pump+accumulator to improve the pressure stability of the liquid supply system,and adjust the speed of the variable frequency emulsion pump according to the pressure change obtained by the pressure sensor to ensure the pressure stability of the liquid supply system.According to the demand,the constant-pressure liquid supply system layout scheme was proposed,and liquid supply pipeline and pumping station operation control strategy were designed.After the field application in the 6301 working face,the remote centralized intelligent liquid supply system run smoothly,which can not only meet the needs of rapid advance of the mining face,but also reduce the energy consumption of the equipment and the workload of the subsequent moving face,and the engineering application effect was remarkable.
