Design a working condition monitoring and intelligent diagnosis system for screw pump based on the ATT7022 chip. Achieve real-time acquisition, storage, analysis of the driving motor electrical parameters of three-phase voltage, current, frequency, active and inactive power, power factor, and the fluid parameters of screw pump production well pressure, pressure, temperature. Accomplish monitoring, alarm and automatic protection the screw pump failure of rod breaking, pump sticking, vacuum, lack of power phase. Using PIC microprocessor to automatic compensate the screw pump motor power, to improve the work efficiency. |
