Key Takeaway: Regular lubrication and inspection of gearbox bearings prevent premature failure and costly downtime.

Case 3: DQ70BSC Washpipe Leak & Packing Wear

Fault Phenomenon: The DQ70BSC’s washpipe assembly developed a drilling mud leak during fluid circulation, reducing circulation efficiency and contaminating the top drive’s internal components. Reason Analysis: Inspection showed that the washpipe packing set (9702032004) was worn and damaged, and the washpipe (9702032007) had minor scratches on its surface—allowing mud to leak. The packing wear was due to long-term exposure to abrasive drilling mud. Solution: Replace the worn packing set (9702032004) with our 5-piece OEM-compatible set and repair the minor scratches on the washpipe (9702032007) using a touch-up kit. Install the new packing according to OEM guidelines, ensuring a tight seal. Our technical team provided guidance on packing installation to maximize service life. After maintenance, the washpipe leak stopped, fluid circulation efficiency was restored, and the DQ70BSC resumed normal drilling operations within 1 hour. Key Takeaway: Regular replacement of washpipe packing prevents mud leaks and protects internal components.
