The batching system sets process parameters (output, thickness, extraction speed), relies on the measurement of parameters by the weighing module and speed measurement module, and automatically adjusts the actual process parameters through intelligent software analysis and calculation, thereby controlling process quality. .

In lubricant petrochemical production, lubricant dosing process has large inertia, time-varying parameters, multivariate coupling, strong nonlinearity and other comprehensive and complex characteristics, therefore, the traditional manual dosing production method leads to large energy consumption in the dosing process, low qualification rate of lubricant process indexes, and low production efficiency. In view of the above problems, a comprehensive automation system of dosing process based on the optimization of lubricant process indexes is proposed. The system consists of process management, intelligent optimization setting control and process control, and discusses the structure, function and intelligent optimization setting control strategy of the system. The system is successfully applied in the lubricant dosing process of a large domestic petrochemical plant, which stabilizes the production process, improves the qualification rate of lubricant process indexes, and realizes optimized control, optimized management and optimized operation, and achieves remarkable application results.

The weighing and dosage system accepts the information from the switching input module, the analog input module and the high counting module, processes the received information according to the program flow and activates the corresponding output module. After processing the received information according to the programmed compensation algorithm, the corresponding values are output.

Polyurethane feeding system control circuit design Based on the automation transformation and engineering expansion of the polyurethane resin (PU) batching system, in view of the problems such as low automation and less visual content in actual batching production, the electrical control circuit was redesigned based on the requirements of the batching process. The comprehensive use of communication technology, PLC technology and WinCC technology constitutes a new wet resin batching system, achieving a high degree of automation and in-depth visualization of the batching process.

The feeding system consists of control, control, bucket machine and other weighing control systems; the electromagnetic vibration feeder is used to uniformly provide granular or powder ingredients from storage warehouses or hoppers to belt conveyors, bucket machines and other batching systems.Especially in aspects such as automatic batching and automatic control, automatic control and centralized management of the production process are realized.

The fixed value filling mode of liquid chlorine cylinder scale adopts electronic label cylinder scale touch screen, bus communication touch screen, wireless network database, etc. The automatic filling machine realizes automatic inspection of liquid chlorine cylinder scale for overdue use or overdue inspection, and automatic inspection of liquid chlorine. Fixed-value filling, liquid steel chlorine bottle file management and circulation management have greatly reduced the impact of human factors, improved work efficiency and safety production factors, and improved the management level of liquid steel chlorine bottles.
