Product Description

Automatic monitoring system of ground pressure fan

System introduction

High pressure wind is an important power source for underground tunneling equipment and coal preparation equipment, and the stability of wind pressure is an important guarantee for the efficient and safe operation of equipment. If the air pressure is too low, the equipment will not work normally. If the pressure is too high, it will cause gas pipeline rupture and leakage and gas equipment is not safe.Due to the continuous work of air compressor and intermittent, periodical work of gas equipment, to ensure stable gas supply of air supply equipment, air compressor needs continuous operation.Generally, multiple parallel work sets are adopted, which leads to the increase of electricity consumption and maintenance cost of air compressor, leading to the waste of energy. At the same time, excessive wind pressure can easily cause pipe damage and bring great safety risks. The automatic monitoring system of air compressor is adopted to realize automatic regulation and closed-loop control of pipeline pressure and air compressor, ensuring the stable gas supply of gas using equipment and ensuring the operation safety of field equipment and gas pipeline and personnel safety.       



Adopting advanced industrial computer, programmable controller, intelligent instrument, data communication technology and various intelligent sensors, the distributed automatic control system is composed of centralized control and decentralized control. The control system consists of four layers: management layer, operation layer, control layer and field equipment. The management and operation layer adopt the technologies of dual thermal standby and dual communication redundancy, and adopt the communication modes of equipment network, industrial redundant Ethernet, local area network and Modbus485 network to form the network structure of integrated management and control. Management upward and enterprise management station to form a high-speed LAN, for managers to provide decision-making information.
