Failure of Hydraulic Torque Wrench in Use
source:Industry News release time:2020-12-15 Article author:Rosit Popular:Air band saw
Common failures of hydraulic torque wrench camshafts include abnormal wear, abnormal noise and breakage. Symptoms of abnormal wear appear before abnormal noise and breakage occur.
The camshaft is almost at the end of the engine's lubrication system, so the lubrication situation is not optimistic. If the oil pump has insufficient oil supply pressure due to reasons such as excessive use time, or the lubricating oil passage is blocked, the lubricating oil cannot reach the camshaft, or the bearing cap tightening bolts.
Abnormal wear of the camshaft will cause the gap between the camshaft and the bearing seat to increase, and the camshaft will undergo axial displacement when it moves, which will cause abnormal noise. Abnormal wear will also cause the gap between the drive cam and the hydraulic tappet to increase. When the cam is combined with the hydraulic tappet, an impact will occur, then result in abnormal noise.
Camshafts sometimes experience serious failures such as fractures. The common causes are rupture or severe wear of hydraulic tappets, severe poor lubrication, poor quality of camshafts and rupture of camshaft timing gears.
