New Energy-saving Control Device Pumping R & D

New project of pumping energy-saving control device is to control a variety of energy into comprehensive energy-saving control device ,which combines motor control, intermittent pumping control, balance control, variable torque pumping three kinds of energy-saving control effect.Electrical energy control system uses sinusoidal pulse width modulation technology. The mechanical properties of the load and motor parameters set reference voltage and reference inverter frequency (the correct reference voltage to set the inverter, reference frequency, which can take advantage of the performance of the drive, but also to meet the requirements of the load on the drive .) System by changing the frequency converter to adjust the motor speed of the unit with the motor power factor in the high run, and can adjust the pumping stroke, pumping work to ensure that pumping at a reasonable operating parameters to achieve energy saving. Between the pumping energy control part expert controller technology that can automatically calculate the pumping shutdown, boot time, to avoid the artificial power, shutdown of the blindness, making pumping more rational system of work, reducing the pumping invalid extraction, but it will also reduce unnecessary accidents, so as to achieve energy-saving purposes.Beam pumping unit and moment balance the energy from the beam control system, motor, balancing-car and drive, position sensors and other components. By changing the location of travel makes the moveing-car the beam pumping unit in the new equilibrium run this once a day. As the relative balance of pumping state runs manually adjust the balance to avoid the previous position to regulate the balance of the inconvenience and drawbacks, to a variable torque balance energy saving.The kind of energy system makes the simulation in the Matlab software platform, the results of simulation shows that the expected energy-savings achieved.
