Compensation Cylinder PT01027700 is a critical hydraulic pressure compensation component exclusively designed for Hydraulic Rock Drills. It excels in harsh mining environments—for instance, underground hard rock mines, high-altitude quarries, tunnel construction sites and vibration-intensive drilling areas.
These settings pose unique challenges for compensation cylinders: frequent hydraulic pressure spikes, uneven drill arm load, intense vibration (up to 40G), abrasive rock dust, and temperature swings. These issues often cause cylinder leakage, movement deviation, pressure compensation failure, or rod wear, leading to drill instability and costly downtime. Yet, Compensation Cylinder PT01027700 maintains uncompromised performance under all these harsh conditions. In fact, it directly addresses five core pain points that plague mining operations.
First, its 45# steel barrel + chrome-plated piston rod (Ra ≤0.1μm surface roughness) withstands 35MPa rated pressure and 70MPa burst pressure. This eliminates leakage or barrel deformation caused by pressure fluctuations in drill hydraulic systems. Second, the ±0.05mm movement precision ensures accurate pressure compensation for drill arm load. Consequently, it avoids drill vibration and improves operation stability by 30% compared to standard cylinders. Third, the load-balancing structural design distributes uneven drill arm force evenly. Likewise, this reduces piston rod stress and extends service life by 130%.
Fourth, the anti-shock design (reinforced piston rod + dampened seal) withstands 40G vibration from drill operation. Above all, this prevents seal damage and piston rod bending, ensuring continuous pressure compensation. Fifth, the wide temperature adaptability (-25°C~110°C) ensures reliable performance in cold high-altitude mines and hot underground drilling environments. On top of that, the IP65 dustproof/waterproof rating blocks rock dust and water ingress, protecting internal components from contamination and corrosion.
Unlike ordinary hydraulic cylinders, this model is engineered for Hydraulic Rock Drills’ dynamic working conditions. To elaborate, the load-balancing design matches the drill’s arm movement requirements, while the chrome-plated rod enhances wear resistance in dusty environments. Thus, it outperforms generic cylinders in service life by 140%, significantly reducing replacement-related downtime.
Our manufacturing team uses precision honing + chrome plating technology for the barrel and piston rod. Furthermore, each unit undergoes 35MPa pressure testing (30 minutes) and leak verification. Additionally, the cylinder undergoes 80,000-cycle compensation trials to ensure no movement deviation or performance degradation.
Notably, it adapts to extreme temperatures from -25°C (high-altitude cold regions) to 110°C (high-load drill hydraulic systems). Moreover, the piston rod passes 500-hour salt spray tests with no rust or plating peeling. In addition, the seals endure 6,000-hour oil immersion trials without aging or leakage.
The cylinder’s flange mounting design integrates seamlessly with mainstream Hydraulic Rock Drill arm systems. It requires no modifications to existing hydraulic pipelines or brackets. As a result, maintenance teams can complete replacement in 25 minutes using standard tools.
Our quality team conducts strict ISO 9001 verification for every unit. We perform pressure resistance tests, movement precision inspections, anti-shock trials and leak verification. Importantly, it complies with ISO 6020/2 international hydraulic cylinder standards.
Compatible with top Hydraulic Rock Drill brands, it serves as a direct OEM replacement. Thanks to its reliability, it reduces cylinder-related failure rates by 93%. Additionally, backed by a 12-month warranty, it lowers annual maintenance costs by 57%.
It not only ensures stable hydraulic pressure compensation for drill operations but also extends the service life of drill arm systems by 85%. Overall, Compensation Cylinder PT01027700 delivers cost-effective, reliable performance for long-term mining operations. Beyond that, it minimizes downtime caused by cylinder failure, maximizing operational efficiency and project profitability.
