1.2 Pre-positioned Field Sand Fishing Working Pain Points Solved

• Universal aftermarket oil spray assemblies deliver uneven lubricant volume, causing local tooth surface dry abrasion on C850 input gear shaft under 290kN sand fishing rated load

• Ordinary pneumatic shift switches suffer spool clamping after 640 cyclic shift operations, leading to asynchronous action of AF500 shifting mechanism

• Generic rubber O-rings and copper washers age rapidly under mixed sand-humidity environment, triggering flange joint hydraulic lubricant seepage on drawworks flow lines

• Non-standard adjusting cushions and shims cannot calibrate transmission assembly gap, resulting in sand fishing roller lateral offset exceeding 0.38mm during reciprocating operation

Exclusive third-party field verified data: this OEM-grade component set extends sand fishing drawworks fluid-lubrication overhaul cycle by 1230 working hours, and reduces pneumatic shift system daily inspection workload by 7 working hours compared with modified universal aftermarket components.

2.2 Core Functional Description

All components realize collaborative operation for sand fishing drawworks power transmission, targeted gear oil spraying, pneumatic gear shifting, lubricant impurity separation and pipeline fluid control. C850 input gear shaft transfers stable sand fishing hoisting torque; matched oil spray line assemblies conduct directional oil supply for high-load gear meshing areas; oil separator isolates air bubbles and metal abrasive impurities inside circulating lubricant; ND12 reversing valve and 2-HA pneumatic switches control shifting mechanism air path switching; pressure sensor monitors real-time pipeline lubricant pressure; stainless ball valve and ejector valve control fluid on-off and pipeline pressure relief; sand fishing roller assembly completes reciprocating sand scraping positioning; winch frame and connecting steel plate maintain overall structural stability; shims, shaft sleeves and adjusting cushions calibrate assembly gap to avoid component lateral deviation; full set sealing fasteners eliminate pipeline and flange lubricant leakage under cyclic vibration.

2.3 Optimized Structural Characteristics

ZLYQC input gear shaft adopts integral carburizing quenching anti-wear treatment; oil spray pipelines adopt inner-wall polishing processing to avoid lubricant impurity adhesion; ND12 valve spool adopts tungsten alloy anti-scuff coating adapted to dusty air medium; thin-wall copper pipes undergo stress-relief annealing bending for accurate pipeline layout; BS G9010 pressure sensor has built-in dustproof sensing cavity; sand fishing roller surface adopts hard chrome plating anti-sand abrasion layer. On-site practical design: unified mounting hole datum for ZLYQC850 mating parts, laser-etched gap calibration scale on shims and cushions, quick-clamp structure for pipe clip assemblies to shorten pipeline replacement time.

2.4 Adaptable Oilfield Working Conditions

Adapt ambient operating temperature ranging from -31℃ to 81℃; fit inland sand-laden wind erosion, underground water vapor corrosion, 24-hour reciprocating vibration sand fishing yard environments; stable operation under 17MPa maximum pipeline lubricant pressure and 300kN peak reducer output torque; compatible with ISO VG220 anti-wear circulating gear oil; applicable for Zone2 dust-intensive onshore sand fishing operation zones.

2.5 Engineer Verified Maintenance Rules & On-site Avoidance Tips

Clean oil spray line inner sediment and filter element impurities every 370 continuous sand fishing hours; replace matched O-rings and copper washers every 780 cyclic operation hours; calibrate pressure sensor numerical value before daily startup; critical avoidance tip: do not alter oil spray hole aperture of ZLYQC oil spray assembly manually, which will break original directional lubrication flow and cause gear partial lubrication failure.
