Introduction of Ro Motor TM Oil Pumping Unit : RoMotorTM is a rod pump tower type long stroke directly driven motor oil pumping unit. By blending the mature technology and design innovation, the pumping unit is furnished with the features of long stroke, heavy load, highefficiency, energy saving.

The working principle of RoMotor : The core technology of RoMotor TM is the Low Speed and High Torque PMSM (Permanent magnet synchronous motor) that is directly coupled to the Top Driving Pulley without speed reduction drive, is controlled by VFD(Variable-frequency drive ) to make the rotor forward and reverse rotation in low speed. Though the friction betweenthe special made Belt and Top Driving Pulley drives the sucker rod up and down for pumping oil from well. Requiresno gear box or four bar linkage.

Field test and application of Ro Motor TM

• The exhibition of RoMotor - On September 14, 2010, one of RoMotor pumping unit was shown on Panjin international equipment and heavy oil technology exhibition, in Liaoning province, China.
• There are also one RoMotor shipped to US and one to Canada to exhibit.
• Liaohe oil field test of RoMotor
• In October, 2010, the exhibited Romotor pumping unit was installed on DUGU4 oil well in
• Liao-he oil field in Panjin, Liaoning, China.
• Tarim oil field try to use of RoMotor
• In April, 2012, five RoMotor pumping unit were shipped to Tarim oil field, and one installe

Conclusion of Ro Motor TM

• Simple structure without gear reducer and four-bar linkage, higher transfer efficiency and less lubrication parts, high reliability , light weight, take up an small area to install RoMotorTM, suitable to be installed place is limited.
• The electric reverse of direction instead of mechanical reversion .It can protect the unit
• and using life is longer than before.
• RoMotor pumping unit has less wearing parts, lower cost of long period maintenance.
• Directly-driven and close loop control. The output horse power of the motor varies
• according to the load down in the well, so it has a high efficiency and energy saving.
• Long stroke and low frequency of stroke which can be adjusted on-site or in remote,
• Though adjust the parameters of unit can increases unit, pump and sucker rod string life,
• improved the transferring efficiency and reliability. The running noise is low.
• The soft-start capability of the VFD requires only 1.5times the rated full load current
• compared to 4 or 6 times on conventional pumping systems.
• Many parameters can be adjusted on site and in remote, and it is easy to execute
• centralized control
• There is a high fill fluid level of the pump because of long stroke length and low stroke
• frequency.
• Long stroke makes pumps compression ration higher. It Is good to eliminate the air lock
• problem.
