Analyze the failures that occur when hydraulic torque wrenches are in use!Pneumatic band saw sale
source:Industry News release time:2021-09-08 Article author:Rosit Popular:Air band saw
Common faults of hydraulic torque wrench camshafts include abnormal wear (a basic type of component failure), abnormal sound and fracture. Abnormal wear often occurs before abnormal noise (decibel (dB)) and fracture (fracture).
(1) The camshaft is almost at the end of the engine lubrication system (including: circulating lubrication system, centralized lubrication system, etc.), so the lubrication condition (Condition) is not optimistic. If the oil is used for a long time, the lubricating oil cannot reach the camshaft bearing cover due to insufficient oil pressure or blockage of the lubricating oil. The inability of oil to enter the camshaft gap will cause abnormal wear of the camshaft (a basic type of component failure).
(2) Abnormal wear of the camshaft (a basic type of component failure) will cause the gap between the camshaft and the bearing seat to increase. When the camshaft moves, it will produce axial displacement and produce abnormal sounds. Hydraulic wrench is the abbreviation of hydraulic torque wrench. It is a professional bolt tightening tool that is powered by hydraulic pressure and provides high torque output. It is used for bolt installation and disassembly. It is often used to tighten and loosen bolts larger than one inch. The hydraulic wrench is composed of a working head, a hydraulic pump and a high-pressure oil pipe. Abnormal wear can also cause a gap between the drive cam and the hydraulic tappet. When the cam and the hydraulic tappet are combined, an impact will be generated, which will produce abnormal sound.
(3) The camshaft sometimes has faults and other serious faults. Common causes are hydraulic tappet fracture or severe wear (a basic type of component failure), severe lubrication, and fracture of camshafts and camshaft timing gears (Gear).
