Product Overview

Core Product Categories & Functional Descriptions

Our components are categorized by their roles in the DQ70BSC top drive system of Gara Altyn Rig, each designed to address specific on-site pain points and ensure smooth rig operation:

• Main Shaft & Mechanical Components: Including 9702020302 bushing, 9702020310 retaining ring, and 4301000470/4301000490 bearings, which stabilize the top drive’s main shaft rotation, solving the problem of shaft jamming or wear during high-load drilling. The 35CrMo crank (P/N 9703330011) and crank pin (P/N 9703330006) can withstand 3800kN load, with a service life of 8,800 working hours, 2,800 hours longer than generic alternatives.

• Seals & Sealing Components: Main shaft O-rings (500X7G, 515X7G, 425X7G), lip seals (B220X250X15G), and compact seal rings (P/N 5304010190) are made of high-temperature, oil-resistant fluororubber, withstanding 135℃ and 48MPa pressure, eliminating oil leakage—a common fault that causes hydraulic system failure and costly downtime.

• Hydraulic Components: Cycloidal gear oil pumps (P/N 9702021500) and variable displacement pumps (P/N 5126000820) ensure stable hydraulic pressure supply, solving the problem of pressure fluctuations that affect drilling accuracy. The 15KW hydraulic pump motor (P/N 3101030310) operates efficiently at 380V/50HZ, reducing energy consumption by 120kWh per month compared to standard motors.

• Hoses & Couplings: F381CACA151508 series hose assemblies (P/N 9702010003, 9702010004) and steel flush-faced couplings (FF-501-8FB, FF-751-12FB) resist high pressure and corrosion, avoiding hose burst or coupling leakage in harsh field conditions. Each hose undergoes 5,000 cycles of pressure testing at 40MPa.

• Electrical & Safety Components: GW200 oil temperature sensor (P/N 3808000072) and YWZ-200T liquidometer (P/N 3804000042) provide real-time monitoring, preventing overheating or oil level abnormalities. Dellner brake assemblies (P/N 5601000060) and friction discs (P/N 5601000070) ensure safe braking, with a response time of 0.8 seconds to avoid rig accidents.

Structural Features

All components are precision-machined and modularly designed to fit the DQ70BSC top drive on Gara Altyn Rig perfectly, making installation and replacement quick and easy—saving 40 minutes of on-site maintenance time per component on average. Key structural advantages include: high-strength materials (ZG35CrMo for guide rings, 42CrMo for wash pipes) with tensile strength ≥ 880MPa, ensuring resistance to deformation under high loads; precision-ground sealing surfaces (surface roughness ≤ 0.5μm) for tight sealing; and anti-corrosion coating on external parts to withstand the dusty, high-humidity environment of Gara Altyn Rig. Additionally, all explosion-proof components meet EX d IIB T6 standards, ensuring safe operation in flammable drilling environments.

Applicable Working Conditions

Our components are specifically tailored for the working conditions of Gara Altyn Rig, which typically operates in semi-arid, dusty environments with large temperature fluctuations. They can operate stably in temperature ranges from -48℃ to 135℃, pressure up to 48MPa, and humidity up to 96%. Whether facing the dusty conditions of on-site drilling or the extreme temperature changes between day and night, our components maintain reliable performance, ensuring continuous operation of the DQ70BSC top drive. They are also compatible with the rig’s TDS system and pipe handler rotation hydraulic motor (OMT-500 151B3005, P/N 5126000790), meeting all operational needs.

Maintenance & Operation Tips

Based on years of on-site maintenance experience with Gara Altyn Rig’s DQ70BSC top drive, our engineers provide practical tips to extend component service life and reduce failures:

• Main shaft & bearings: Apply high-temperature grease every 190 working hours; check for wear or looseness every 300 working hours. Avoid over-tightening fixing screws (M12X25), as this can damage the main shaft—our engineers remind that proper torque (45N·m) is critical to prevent component damage.

• Seals: Inspect for aging, cracks, or deformation every 270 working hours; replace seals if they lose elasticity. Clean the sealing surface before installation to avoid debris causing leakage—this simple step reduces seal failure by 65%.

• Hydraulic components: Check oil cleanliness every 480 working hours; replace hydraulic oil every 1450 working hours. Use only compatible oil grades to avoid damaging gear pumps and valves—using incorrect oil can reduce component life by 3,500 hours.

• Hoses & couplings: Inspect hoses for wear or bulging every 200 working hours; replace hoses that show signs of damage. Tighten couplings to the correct torque (35N·m) to avoid leakage, especially in dusty environments.
