The motor reversing pumping unit is an electronically controlled, beamless pumping unit. Utilizing variable frequency control (VFD) technology with Permanent Magnet Synchronous Motors (PMSM), it achieves automatic speed regulation, reversible operation, and intelligent control. This design simplifies the transmission mechanism, delivering superior performance and enhanced reliability, making it a premier example of a high-performance mechatronic product.
Featuring a stable tower-type structure, the unit uses AC variable frequency technology to control a permanent magnet synchronous motor (PMSM), driving the drum in forward and reverse rotation. Through friction, the load belt wrapped around the drum converts this rotation into vertical reciprocating motion. With one end connected to the counterweight box and the other to the polished rod, the belt drives the polished rod up and down to lift well fluid via the sucker rod pump.
By eliminating components like the gear reducer and mechanical reversing mechanism, the simplified design features fewer transmission links. This results in higher efficiency, lower operating noise, and significantly reduced maintenance workload.
Utilizing a gravity-based symmetric counterbalancing system, the counterweight box features a dedicated compartment for weight adjustment. By simply adding or removing counterweights, the unit achieves superior balancing performance.
Featuring an integrated folding design, 95% of the unit is pre-assembled at the factory, making on-site installation incredibly quick and hassle-free.
Featuring an intelligent control system, it allows for easy parameter tuning. Both stroke length and pumping speed can be flexibly adjusted within their operating ranges, with independent settings for upstroke and downstroke speeds. This delivers significant energy savings and efficiency gains in heavy oil and fluid-deficient wells, effectively boosting both pump efficiency and overall oil recovery.
Powered by a low-speed, high-torque permanent magnet motor and advanced variable frequency control, the unit features fewer transmission links and exceptional operating efficiency. This delivers remarkable energy savings, reducing overall power consumption by 20% to 45%.
The low-speed, high-torque permanent magnet motor drives the drum via a synchronous belt. Featuring a gear reducer-free design, the entire unit operates smoothly with minimal noise.
Featuring an integrated skidding mechanism, the unit can be quickly and easily moved to provide wellhead access. This eliminates the need for hoisting or working at heights during relocation.
Featuring a design free of gear reducers and chain drives, it ensures quiet operation and completely eliminates the risk of lubricating oil leaks.
