2. Core Function & Structural Characteristics

Functionally, these JWS400 drilling pump spare parts undertake five core system responsibilities: mechanical power transmission, hydraulic pressure regulation, lubrication system circulation, pressure data monitoring, and pipeline connection sealing. Crankshafts, connecting rod assemblies, cardan shafts and bearings form the complete power transmission system, converting power input into stable reciprocating pumping motion to ensure continuous fluid delivery. Seals, retainers and rubber buffer blocks achieve multi-layer sealing and shock absorption, preventing hydraulic fluid leakage and external impurity intrusion while reducing mechanical vibration impact. Lubrication pumps, filter elements and radiator assemblies maintain the normal operation of the lubrication and heat dissipation system, reducing component friction wear and avoiding high-temperature overheating failure. Multi-specification pressure gauges and proportional solenoid valves realize real-time pressure monitoring and precise hydraulic regulation, ensuring pump operation parameters stay within the safe range. Standard couplings, nipples and hose assemblies guarantee stable connection and fluid transmission safety of the entire hydraulic pipeline system.

Structurally, all JWS400 pump spare parts adopt industrial heavy-duty optimized designs suitable for long-cycle drilling operations. Core transmission components such as crankshafts and crossheads adopt integral forging and precision machining processes, with reinforced structural rigidity to resist high-load torsion and fatigue deformation. Sealing and buffer components use high-strength composite rubber and polymer materials, with anti-aging, wear-resistant and corrosion-resistant structural optimization. Filter elements adopt high-precision multilayer filtration structures to efficiently intercept fluid impurities and protect precision valve components and pump bodies. Modular design is adopted for all wearing parts and standard accessories, enabling fast on-site disassembly and replacement without secondary processing, greatly shortening maintenance downtime. The integrated repair kit design covers all vulnerable parts required for overall overhaul, realizing one-stop equipment maintenance.
