On February 2, the joint commissioning task of Anqing Petrochemical Aviation coal railway factory loading control system was over. Anqing Petrochemical Electric Instrument Department completed the expansion project of this control system and effectively expanded the shipping channel of aviation coal.
In order to expedite the delivery of aviation coal and make the two channels of railways and waterways go hand in hand, the railway industrial station needs to rebuild the original quantitative loading system and the electrical instrument department is responsible for the transformation of the loading control system. Car control system, and the original three sets of diesel loading control system profit update, to meet the aviation loading requirements.
The transformation started from early January 2010. In the equipment installation phase, the instrument department, the refining and electrical work area, and the Ministry of Transport worked closely with each other to complete the installation of two mass flow meters, loading valves, Overflow alarm switch, oil and gas recovery valve, anti-static grounding clamp and other equipment installation.Limited the old three sets of loading system batch controller, O-ball valve, pneumatic control box, oil selection valve protective removal, Shift installation.At the same time, Department of Instrument Instrument Maintenance Center is responsible for loading card control system card installation.
January 19, PLC control system began wiring. Instrument maintenance center DCS fourth class is responsible for the field control equipment signal one by one access control system. For the sake of caution, the center technician Zhu Hong first draw a detailed wiring diagram, please design In order to be identified before they start to access.At the same time, do a good job of marking.After all the wiring check check, the system into the configuration, the next phase.In order to prevent the process of loading on-site valve without action, the center in close contact with the transport Ministry of operations, choose the scene without loading operation carried out, in order to safely complete the batch controller configuration, commissioning and configuration of the host computer configuration work is completed, February 1, Department of Electrical Instrument collaboration , On the control system and field instrumentation joint commissioning to February 2, the joint commissioning task ended.
