Hydraulic valve bodies adopt precision internal honing technology, maintaining stable pressure regulation accuracy under 7500PSI rated working pressure with no pressure attenuation during static holding. Mechanical structural parts adopt heat-treated alloy steel, reaching 7200 hours of fatigue-resistant continuous service life. DQ70BS dedicated tooth plate adopts integral precision forging process, with higher clamping force uniformity than ordinary accessories. All parts follow strict OEM dimensional tolerance standards for direct plug-and-play replacement without on-site modification.

4. Applicable Working Conditions

This spare parts suite is exclusively applicable to VARCO TDS9S, TDS10 and Beishi DQ70BS top drive systems, adapting to 7000-meter deep well drilling, desert high-temperature zones, northern low-temperature oilfields and land heavy-load rig working conditions. It supports 24-hour continuous heavy-load operation and high-frequency start-stop cycles, fully meeting ultra-deep well exploration, directional well construction and daily equipment overhaul operational demands.

5. Professional Maintenance & Engineer Operational Suggestions

Field engineers need to calibrate CPU and PLC module signal parameters every 500 working hours to eliminate data deviation faults. Replace gear oil filters and aging sealing parts every 1000 working hours to ensure lubrication and sealing performance. Inspect hydraulic valve pressure regulation sensitivity quarterly and clean valve body impurities to avoid jamming. Check brake pad wear and structural fastener tightness monthly to prevent mechanical failure caused by vibration loosening. Test explosion-proof plug and circuit safety performance regularly to eliminate electrical safety hazards.
