Low position traction long stroke pumping unit

· Technical advantages

1. The low-speed high torque motor drives the drum winding broadband to achieve traction load, with good adaptability and high system efficiency;

2. No gearbox or transmission chain, simple mechanism, no need for oil lubrication;

3. Low level setting of the power system, convenient maintenance and repair;

4. Equipped with a counterweight box lifting device, the well repair and relocation machine does not require the use of a crane.

5. Application of energy-saving intelligent control system, energy-saving and consumption reducing, with complete control functions and convenient operation.

6. Simplify the transmission mechanism, improve application performance, reduce environmental impact, reduce maintenance costs, and extend equipment maintenance cycles.

· An intelligent energy-saving AC frequency conversion control system with functions such as intelligent control, remote control, and automatic protection. Can achieve

1. Adjust and set the up and down stroke speeds separately, with stepless adjustment;

2. Set the reversing acceleration and acceleration segment length to reduce the impact of inertial loads;

3. Switch between manual and automatic operation modes for convenient parameter debugging;

4. Functions such as phase loss protection, overload protection, loss of load protection, overspeed protection, overvoltage protection, undervoltage protection, etc;

5. Control the operation of the lifting device to achieve installation and relocation operations;

6. Energy storage balance, collecting and storing energy on the down stroke, utilizing it on the up stroke, saving 30% electricity;

7. Meet the requirements of oilfield informatization, remote operation monitoring, and remote data transmission.
