Core advantages

Designed around the operating requirement.

Full-Series Model Coverage & Wide Rig Adaptability

The complete ZP-series model portfolio covers multiple bore diameters and static load grades, perfectly matching conventional workover rigs, medium drilling rigs and ultra-deep well heavy-duty drilling rigs. Each model adopts standardized installation dimensions and interface specifications, realizing seamless compatibility with mainstream oilfield rig brands. It meets the full-range operational demands from shallow well routine maintenance to ultra-deep well high-load drilling construction.

Heavy-Duty Load-Bearing & High-Torque Stability

The main body adopts high-strength alloy cast steel integral forming process with overall structural reinforcement, effectively resisting heavy-load impact and torsional stress. Precision hardened helical gear pair ensures efficient power transmission and stable torque output, avoiding jitter and torque attenuation during long-duration rotary operation. Excellent static and dynamic load performance guarantees safe bearing of drill string and casing weight in complex well conditions.

Dual-Seal Protection & Low Failure Rate

Equipped with upgraded multi-layer combined sealing structure and independent lubrication protection system. The optimized dust-proof and anti-leakage design effectively isolates sand, mud and humid air in well sites, preventing internal gear wear, lubricant deterioration and impurity deposition. The fully enclosed lubrication loop ensures uniform oil film protection for transmission components, greatly extending service life and reducing unexpected downtime.

High-Precision Operation & Strong Anti-Vibration Performance

Adopts strict dynamic balance calibration and precision assembly technology, realizing low-vibration and low-noise rotary operation. The matched master bushing and roller support structure ensures stable rotary accuracy, effectively reducing drill string vibration and wellbore deviation during drilling. It significantly improves wellbore quality and drilling construction efficiency for high-precision directional drilling and ultra-deep well projects.

Full-Climate Harsh Environment Adaptability

All structural components adopt sand-proof, anti-corrosion and weather-resistant protective coating. Core transmission parts adopt wide-temperature anti-aging and wear-resistant configuration, supporting stable continuous operation within -40℃ ~ +55℃. It perfectly adapts to extreme working environments such as desert high temperature, Gobi wind-sand erosion, muddy well sites and high-altitude low-pressure cold plateaus.

Modular Structure & Convenient Maintenance

Adopts standardized modular assembly layout with highly universal wearing parts and accessories. The external centralized lubrication interface and detachable structural design simplify daily grease injection, inspection, gear maintenance and bushing replacement. The reasonable internal spatial layout reduces maintenance difficulty and effectively lowers long-term operation and maintenance costs for oilfield teams.
