      The system consists of a vacuum pump motor and pump motor, the MCU to complete the pipeline pressure testing and tank temperature control. Pressure sensors to collect data and send the single-chip processing. The system uses two sets of heating tube, each power is 24 kW. Temperature sensor used to collect data and send single-chip processing. When the temperature reached requirements, cut off the vacuum pump motor, and at any time to display the current temperature, trip temperature of the contactor can be set by DIP disk into the microcontroller. The motor can only be in the system forward, not reverse, the control circuit should have a reverse alarm device.
    The main circuit air switch and contactor to achieve the control loop consists of single chip control system to achieve. The startup sequence is: oil pump motors, vacuum pumps, motors, heating pipe. Two groups of heating pipes can be separately heated and shut down, but only after the start of the vacuum pump motor heat pipe can be up and running.
