Key Features of the Pumping Unit Series:
Long Stroke & Low Speed: Enables high pump fill coefficient and reduces hydraulic shocks, thereby minimizing the wear on downhole equipment and lowering operational costs.
Large Working Space: Offers ample room for maintenance, making well servicing more convenient.
Belt Drive: Utilizes high-strength, heavy-duty belts with superior elastic cushioning to minimize reversal shocks and promote smooth operation of the sucker rod string.
Automatic Re-positioning Device: Ergonomic design greatly reduces labor intensity and streamlines both operation and maintenance.
Optimized Structural Analysis: Employs finite element analysis (FEA) software for optimizing primary components, resulting in minimal rigidity deformation and stable, reliable performance.
Reliable Braking System: Fitted with a robust mechanical brake; optional electromagnetic braking is available upon customer request for added safety.
Fully Enclosed & Collapsible Design: Ensures safe, easy transport and installation.
Durable Components: Uses wear-resistant bearings, long-life belts, and heavy-duty chains to guarantee high reliability and extended service life.
Mechanical Balancing & Advanced Lubrication: Equipped with a refined lubrication system, automatic protection devices, and an enclosed structure to minimize maintenance frequency and extend overhaul intervals, boosting oil output.
Automated Control Optional: Whole-unit automation can be configured as per user requirements, allowing automatic stroke adjustment and unattended automatic oil production.
