1. Features

    When the permeability capacity of well is tremendously lower than that of design of a pumping unit, the wells are in the condition of seriously insufficient oil supply, For the purpose of energy saving, mechanical wear should reduced and pump efficiency should be improved, At present an automatically control system is often used, that is when insufficient oil supply in the well is detected, the pumping unit stops running, after the liquid level is recovered it runs again, such repeated,

• Arrangement function: parameters can be set by using keyboard.

• Automatical learning function: on the bases of setting the initial time of intermittent pumping, according to the condition of fluid production, automatic learning is carried out, the optimal intermittent pumping time is calculated. Of the ability of fluid production changes, it is automatically adjusted.

• Function of automatic detection and control: based on the detected current/ power signals, through analysis and judgment, an internal optimized control algorithm is for the optimal control of intermittent pumping.

• Function of pre-warning: before the computer is started, 2~3min sound warning (ringing warning), and then pumping unit is started.

• According the actual needs, the shortest and the longest pumping times can be preset, thus the situation of over-length of pumping time or for special needs can be avoided.

• The historical record of pumping time, shut in time is available, power consumption is metered for indicating the equilibrium coefficient.

• Function of expansion: by adding the digital transmission radio or GPRS module, the remote real-time transmission of data is implemented and real-time remote control of start and stop and adjustment of intermittent pumping are carried out, the pumping time setting, the control of intermittent pumping can be realized through the control center, thus manual control is available in the control center.
