2. Standardized Full-Dimension Product Introduction

2.1 Basic Product Overview

This integrated spare parts portfolio covers full-category consumables for 3NB-1600F mud pump power end and fluid end, including multi-size ordinary/bi-metal liners, matched GRP piston inserts, hardened/stainless piston rods, ZPEC ZM valve assemblies, R-series ring gaskets, power-end bearing sleeves, crosshead assemblies, relief valves, damping devices, standardized threaded fasteners, lubrication accessories, spraying assemblies and explosion-proof pressure gauges. It covers 4inch to 6-1/2inch liner and piston full size specifications, matches original pump installation datum, thread size and compression groove dimension completely.

2.2 Core Functional Description

Deliver stable high-pressure mud circulation via matched liner-piston assembly; realize one-way mud flow control via API 6# valve assembly and ZPEC valve spring; absorb pipeline surge pressure via KB-75 surge damper and suction damper; stabilize crankshaft linkage operation via self-centering bearing and left/right main bearing sleeve; isolate mud and lubricating oil via multi-spec oil seals and R-series gaskets; eliminate assembly clearance deviation via graded shim sets; realize overpressure protection via JA-3 and YYFJ-L20 relief valves; maintain circulating lubrication via gear oil pump and spraying pump assembly; block external mud splashing via integrated mudguard and shield components.

2.3 Integrated Structural Characteristics

Adopt centrifugal composite double-layer liner anti-wear structure, split modular crosshead positioning structure, embedded retainer ring limit structure, gradient compression R-gasket sealing structure, split pin anti-shear bolt structure, integrated air-bag pressure buffer structure, standardized NPT threaded quick-connect pipeline structure. All pressure-bearing cavities adopt arc transition polishing to eliminate stress concentration; all key threaded parts adopt thread anti-corrosion coating to reduce disassembly seizure risk during periodic overhaul.

2.4 Applicable Working Conditions

Adapt to water-based drilling mud, weighted barite mud, low-corrosion formation return mud; applicable mud density range 1.03g/cm³ to 2.40g/cm³, rated working mud pressure 35MPa, ambient operating temperature -20℃ to 75℃, 24-hour intermittent reciprocating operation mode. Suitable for onshore deep vertical well, high-inclination directional well drilling mud feeding, well killing operation and underground pressure balance working scenarios.

2.5 On-site Engineer Maintenance & Risk Avoidance Guidance

Complete pump overhaul cycle is 1600 working hours; replace all R-series ring gaskets and GB/T3452.1 standard O-rings during fluid end disassembly; fasten main bearing 2 1/2-8UN-3A bolts to calibrated 420ft-lbs installation torque; clean draining filter assembly every 260 working hours to avoid lubricating oil impurity blockage; match paired liner and piston with unified caliber only; apply 277 sealant and 242 seal glue evenly on gasket joint surfaces; inspect shear pin and locking spring pre-tightening force before startup; prohibit mixing non-standard retainer rings for crankshaft positioning assembly.
