Fully dimensionally consistent with original INGERSOLLAND YH80 rock drill spare parts, matching OEM part numbers IR-YH80, 32286419 and 20147592. Standard size design allows direct disassembly and replacement without cutting, grinding or secondary processing, greatly lowering on-site maintenance difficulty.
Core vulnerable diaphragm leather cups adopt high-toughness imported PU material with anti-fatigue reinforcement layer; all sealing rings use high-performance FKM fluororubber plus PTFE anti-extrusion backup rings. Resist hydraulic oil corrosion, rock dust abrasion and high-frequency impact fatigue, stable performance under -30°C to 120°C wide temperature range.
All spare parts pass strict 14MPa high-frequency impact cycle testing before delivery. Effectively prevent diaphragm cracking, oil leakage at the impact chamber and rotary motor oil seepage, stabilize hydraulic impact power and impact frequency, guarantee continuous stable drilling efficiency of rock drills under heavy rock working conditions.
Covers all diaphragm and sealing consumables required for full machine maintenance of YH80 drifter. One set meets one-time full overhaul demand, avoids repeated separate procurement of scattered parts, shortens field repair time and cuts overall equipment operation maintenance cost.
Every finished kit undergoes air tightness, high pressure impact, aging and abrasion cycle tests, fully meets Ingersoll Rand original factory quality standards. Stable long-term operation in harsh underground mining and tunneling environments with low failure rate.
Perfectly matched with INGERSOLLAND YH80 hydraulic diaphragm rock drills on all kinds of heavy-duty drilling equipment: • Underground mine tunneling drilling rigs • Open-pit quarry surface drilling jumbo • Hydraulic rock bolting rigs • Tunnel excavation engineering drilling equipment • Metallurgical mine hard rock drilling equipment • Mobile hydraulic drilling machinery for infrastructure construction
