Water Pressure Control System :
Based on the actual statistical analysis of the water consumption of the previous vulcanizer workshop, the automatic pumps of several of them were selected to participate in the experiment of automatic voltage regulation control. Among the components of the automatic control system, the pressure sensor, pressure controller, PLC and inverter internal PID and soft starter constitute a closed control system to achieve constant pressure control of the vulcanizer.
In the case of the automatic control system, the vulcanizer supply system was operated from the original two power frequency two standby improvements for one frequency conversion operation, one soft start to standby.
In the experiment, the pressure sensor converts the detected pressure signal into a standard current signal and transmits it to the pressure controller and the AC inverter. By comparing the pressure transmitted to the frequency converter and the pressure setting inside the gas, the speed of the water pump is automatically adjusted by the AC frequency converter to ensure that the water pressure in the vulcanization is constant.
The lifting speed of the vulcanizer AC frequency converter and the adjustment time of the PID regulator can be adjusted within a certain range. When the water consumption is relatively large, the speed of the water pump can be adjusted as fast as possible to ensure the normal use of the water for sulphurization, and the fluctuation of the water pressure is greatly reduced.
Vulcanizer Control System:
After the vulcanizer is clamped to the bottom, the vulcanization process begins. First, the water will be turned on once, switched to secondary water, and then the formal vulcanization process. The on-site control system of the vulcanizer transfers the vulcanization machine's initial vulcanization signal to the vulcanizer process control station in the central control room.
The gas source of the regulating valve of the external pressure steam starting film of the vulcanizing agent is turned on, and the external steam enters the steam chamber of the vulcanizer. At this time, the external temperature measuring element transmits the temperature signal measured in the steam chamber to the field control cabinet as a resistance value. The intelligent digital display device converts this resistance value into a current signal, and then transmits the current signal through the signal transmission cable to the process control station in the central control room.
The control station will transmit the relevant signals to the upper monitoring machine through the network card, so that the data can be observed and recorded. At the same time, the control station analyzes the signal detected during the vulcanization process and converts it into a current signal to the Liu Huade site. The electric valve positioner of the vulcanizer automatically controls the opening of the pneumatic diaphragm regulating valve according to the transmitted current signal, thereby controlling the steam quantity of the vulcanized steam, and realizing the automatic control and adjustment of the external pressure temperature of the vulcanization process.
