Oil Distribution Sleeve / Drilling Machine With Oil Sleeve 45 Steel Casting / Sintered Tin Bronze Bimetal Sleeve Metallurgical Combination
Main features: steel and copper metallurgy combination, supporting coal mine tunnel drilling machinery field, direct factory price, good quality and low price.
Mainly matched: (ZDY-1200S[MK-4], ZDY-1500[MK-5], 1900S[MKD-5S], ZDY-3200S, ZDY-4000S) (ZY-650, ZY-750, ZY-1250 ZY-2300, ZYW-2000 linkage drilling rig, ZYW-3000 linkage drilling rig, ZYW-4000 linkage drilling rig, heavy duty pumping station ZYW-4000 (ZX) drilling rig, and new accessories that are continuously improved with the main engine parts.
Main advantages: At present, the mechanically pressed inlaid connection between the base of the oil distribution sleeve and the inner sleeve often causes hydraulic oil to leak from the joint gap, which reduces the hydraulic transmission efficiency of the drill. Our company's process is compounded with carbon steel by internal copper alloy centrifugal casting, vacuum sintering and other process technologies. The advantage is that the oil distribution sleeve has high wear resistance and seizure resistance, and solves the problems of quick wear of the oil distribution sleeve, large leakage amount, easy to lock and pull the sleeve.
