Control device of roller type centrifugal casting machine

A control device of a roller type centrifugal casting machine comprises a PLC (programmable logic controller) module, a power source, a centrifugal machine, a frequency converter, a water spray device, a spraying device, a travel switch, a time relay, a plurality of sensors, a plurality of command input switches and a plurality of relay switches. The PLC module is provided with an analog input module, a digital input module and a digital output module, the power resource is used for powering the PLC module, the centrifugal machine, the frequency converter, the water spray device, the spraying device and the sensors, the digital input module of the PLC module is used for acquiring on-off state signals of the command input switches, the travel switch and the time relay, the digital output module of the PLC module is used for outputting the on-off state signals acquired by the digital input module to the frequency converter and the relay switches, and the analog input module is used for transmitting cooling water pressure and flow analog signals, mold temperature signals and molten iron temperature signals during pouring, which are acquired by the sensors, to a CPU (central processing unit). The control device of the roller type centrifugal casting machine is high in automation and easy to operate.
