The integrated beam pumping unit designed and produced based on Sine Electric’s EM730 special frequency converter for beam pumping units 

has automatic energy-saving control to solve the problems of low operating efficiency, low power factor, and large waste of electric energy for pumping units. 

By summarizing the mechanical parameters of various types of beam pumping units, the mathematical model of the suspension point load and the real-time operation of the motor is established. 

Through real-time detection of electrical performance parameters such as motor output current and output power, the change of suspension point load is calculated, 

and then the dynamometer diagram is obtained.

Intermittent extraction function：

With the functions of automatic intermittent pumping and manual intermittent pumping, it can be used for intermittent oil recovery

Intelligent control：

The special software can control the operation of the pumping unit more reasonably according to the electrical parameters of the input 

and output terminals of the frequency converter and the parameters of the oil well sensor.

Parameter monitoring：

LCD keyboard can provide multi-line display, which is convenient for viewing various operating data and historical fault query.

Special accessories：

The special braking unit can provide continuous and frequent high-voltage pulse braking operation. 

Built-in DC reactor and EMC filter, reduce inverter interference, improve power factor, and improve control stability.

High performance：

It has the function of low-speed and high-torque output, wide speed range, high control precision, strong low-frequency load capacity, and high torque control precision.

High reliability：

It has wave-by-wave current limiting capability, which greatly reduces the number of skipping flow protections. 

The frequency can be automatically adjusted according to the bus voltage change caused by the fluctuation of the power grid, 

and the power-failure ride-through function can be realized.

Extend Available：

Optional touch screen, simple and intuitive operation. The remote transmission module is optional, 

and the operating parameters of the oil well can be viewed on the mobile phone or computer.

Adapt to various types of motors：

Supports three-phase asynchronous motors and permanent magnet synchronous motors.

According to the different needs of customers, Sine Electric provides non-standard customized system integration business, 

more than 10 units of integrated control cabinets of upstream beam pumping units can accept orders, and large quantities offer discounts.

Special Variable Frequency Drive

According to the commonly used power of beam pumping units, Sine Electric provides EM730 dedicated inverters for beam pumping units, 

with a total of 4 power sections: 22KW-45KW, and other powers can also be customized according to requirements.
