2. Core Product Introduction
2.1 Functional Description
Each component undertakes independent core functions in pump and drawworks operation. Brake band and matched brake pads provide stable braking torque for JC28K drawworks to control drilling lifting and lowering operations. Crosshead, slider assembly and guiding inserts ensure linear reciprocating motion of pump power end, eliminating motion deviation. Piston assemblies, piston rubber and sealing washers maintain high-pressure sealing performance of pump fluid end, preventing medium leakage. Hex nuts, lock springs and pin fasteners realize anti-loosening fixation of high-vibration operating parts. Oil pumps, oil filters and hydraulic plunger pumps guarantee stable hydraulic circulation and lubrication of the whole equipment, reducing frictional loss of moving parts.
2.2 Structural Characteristics
All parts adopt integrated forging and precision turning process with modular assembly structure. Wear-resistant parts such as wear ring and wearing pad seal adopt high-hardness alloy coating treatment, with surface roughness controlled within Ra0.8μm. Threaded fasteners including M24, M27, M39 and M42 series adopt paired precision matching design to adapt to high-frequency vibration working conditions. Sealing components are customized with multi-size specifications (140mm/170mm/180mm) and composite rubber materials, with compression resilience rate reaching industrial advanced level. Guide plate and liner flange adopt positioning foolproof structure to improve on-site assembly efficiency and avoid installation errors.
2.3 Applicable Working Conditions
This series of spare parts is suitable for onshore and offshore oil and gas drilling, deep well exploration and well workover operations. It stably adapts to high-pressure working environment of 0–42MPa, heavy-load continuous operation and high-frequency vibration scenes. It perfectly matches full working condition cycles of 3NB-1600HL drill pump, Weatherford MP-16 mud pump and JC28K drawworks, and is compatible with conventional drilling fluid medium and harsh temperature environments of -30℃ to 85℃.
2.4 Maintenance Suggestions
Engineer practical operation suggestions: Replace piston rubber and sealing washers every 2800 hours of continuous operation; inspect brake pad wear every 700 hours and replace in time if thickness loss exceeds limit; clean oil filter and check hydraulic pump operating status every 350 hours; calibrate crosshead and slider positioning accuracy every 1400 hours. Avoid mixed installation of standard and customized fasteners to prevent structural loosening. Regularly check nipple joint rubber ring and frontal wiper panel seal ring to eliminate hidden leakage risks.
