Structural Design Features
These liner washer parts are designed for field durability, convenient maintenance and efficient cleaning, fully adapted to harsh drilling site environments:
- Modular Pipeline Design: Standardized flanges, joints and hoses realize segmented disassembly and replacement, making it easier to clear blockages and replace damaged parts without dismantling the whole equipment.
- Multi-Layer Sealing Structure: Double gaskets and precision joint design are adopted at key pipeline connections, effectively preventing high-pressure flushing liquid leakage and improving cleaning efficiency.
- Stable Fixed Support Structure: Special mounting brackets ensure stable installation of the washer equipment, reducing vibration during operation and lowering the failure rate of internal components.
- Quick-Release Hose Connection: Standard hose clamps and joint cores realize quick disassembly and assembly of rubber hoses, simplifying on-site maintenance and replacement steps.
Applicable Operating Conditions
This series of liner washer parts performs reliably in various harsh drilling site scenarios, with strong environmental adaptability:
- Onshore Drilling Sites: Land deep-well rigs, desert drilling platforms, mountain and frozen soil drilling areas, adapting to high-dust, large temperature differences and outdoor open-air operation.
- High-Mud Concentration Environments: Suitable for high-viscosity and sand-containing drilling mud conditions, resisting mud blockage and particle erosion of pipelines and sealing parts.
- Continuous Intermittent Operation: Adapting to long-term intermittent start-stop working mode of the liner washer, maintaining stable performance and sealing effect.
- Conventional Water Quality Flushing: Suitable for conventional clean water flushing of mud pump cylinder liners, meeting daily cooling and cleaning requirements.

On-Site Fault Repair Case Studies
Case 1: Damaged Gasket Causing High-Pressure Liquid Leakage
A drilling site’s LSNOI 3NB-1600 mud pump liner washer had serious high-pressure water leakage at the pipeline flange. On-site inspection found that the rubber gasket (107.214.02, δ0.35) was aged and damaged due to long-term mud erosion and temperature changes, losing sealing performance. Maintenance personnel replaced the damaged gasket, re-tightened the matching bolts evenly, and the leakage fault was completely eliminated, restoring normal flushing work.
Case 2: Clogged Centrifugal Liner Washer Leading to Insufficient Pressure
A land drilling rig’s liner washer showed insufficient flushing pressure and weak water output. The fault was caused by mud particle deposition blocking the internal passage of the centrifugal liner washer (107.186.00). Technicians disassembled and cleaned the centrifugal pump, replaced worn internal sealing parts, and the flushing pressure returned to the normal range of 0.3-0.6MPa.
Case 3: Cracked Rubber Hose Triggering Pipeline Leakage
An offshore auxiliary drilling site’s liner washer had liquid leakage from the rubber hose (HG4-761-74, φ25). Long-term outdoor exposure and mud corrosion caused the hose to age and crack. Workers cut off the damaged hose section, replaced it with a new standard rubber hose, fastened it with matching hose clamps, and quickly restored the normal pipeline circulation.
