Intelligent Electric Drum Pumping Unit

Stroke and frequency could be stepless adjusted at rated range, ascending and disacending polished rod could be adjusted respect

Working principle

Through the motor’s positive-negative rotating to drive the cycloidal two-speed reducer and drive the drum forward and reverse rotating, which makes the polish rod linked with belt that covering drum do vertical reciprocating motion, then polish rod drives the pump swabbing oil. One end of belt links with polish rod, another end links with counterweight box. According to the indicator diagram or running current curve to adjust the weight of counterweight box, realizing precise balance

Characteristics: 1. Intelligent design:

Much longer stroke length, which can achieve 8MStroke and frequency could be stepless adjusted at rated range, ascending and disacending polished rod could be adjusted respectively, delay automatic starting, and automatic detect the temperature of control cabinet. 2. Perfect protections: Automatic protection for stop and record fault type and time, besides, convenient maintenance for power undervoltage, overpressure and lack of phase. 3. High security4. Be easy to operate and intelligent adjustment, simple maintenance and low failure rate. 5. Convinent to remove and workover treatment6. High-power motor and high efficiency
