Pumping Unit Electric Control System
The pumping unit frequency conversion energy-saving electric control
system can accurately monitor various parameters of the motors and oil well
parameters (pressure, displacement, indicator diagram, etc.) in real time, and
collect data to IPC through sensors. And IPC displays the above parameters
in the form of journal sheets and various curves, and according to the initial
parameter settings, IPC alarms and real-time on-site controls the parameters
exceeding the upper or lower limits to extend the fault-free working time of
the well.
The system ensures normal operation of various equipment of oil wells and
avoids equipment damage by monitoring various parameters and automatic
protections of the equipment, thus saving a lot of manpower and material
resources and reducing the labor intensity of workers. At the same time, it can
effectively save energy to use frequency conversion devices to control motors.
