Cooling system assemblies eliminate accumulated heat of hydraulic oil and electrical cabinets, supporting 24-hour non-stop drilling operation.
2.3 Structural Features
All parts adopt modular integrated original structure with unified standard installation interfaces, supporting fast on-site replacement without secondary debugging or mechanical modification. Hydraulic pipe fittings and valves adopt 37-degree female seat sealing structure to resist oil medium erosion and pressure impact. Electrical circuit components feature built-in surge suppression and dustproof encapsulation. Well control sealing parts adopt multi-layer composite polypak structure for enhanced compression recovery performance. Cooling coolers adopt professional HERESIT coating to resist corrosion and high-temperature aging in harsh oilfield environments.

3.2 Engineer On-Site Maintenance Suggestions
Based on long-term oilfield overhaul experience, targeted maintenance can effectively extend component service life. Replace inverter fuses and trigger board accessories every 1800 working hours to avoid signal failure. Clean hydraulic coolers and replace aging blower motor capacitors every 600 hours to guarantee heat dissipation efficiency. Replace IBOP sealing kits and backup rings every 2800 working hours to prevent micro-leakage. Inspect hydraulic hose assemblies and cylinder pin retainers regularly to eliminate hidden structural faults. Never install non-standard parts to avoid system hydraulic and electrical matching errors.
