Cause Of Failure Of Hydraulic Torque Wrench

Hydraulic torque wrenches Common faults, causes and maintenance: High-power hydraulic torque wrench is a part of the piston engine. Its role is to control the valve opening and closing action. In general, in a straight-through engine, a cam corresponds to a valve, a V-type engine or a horizontal opposing engine is a cam that shares every two valves. While the rotor engine and the valveless valve engine due to its special structure, do not need cam.Hydraulic Torque Wrench

In some cases, the camshaft failure is caused by human reasons, especially when the engine is not properly disassembled for the camshaft. Such as disassembling the camshaft bearing cover with a hammer strong percussion or with a screwdriver to push the pressure, or install the bearing cover when the wrong position caused by the bearing cover and the bearing does not match, or the bearing cap tightening bolts tightening torque is too large and so on. Camshaft sometimes rupture and other serious failures, common causes of hydraulic tappet broken or serious wear and tear, severe lubrication bad, camshaft poor quality and camshaft timing gear rupture.Hydraulic Torque Wrench

Abnormal wear of the camshaft causes the gap between the camshaft and the bearing housing to increase, the camshaft movement will occur when the axial displacement, resulting in abnormal sound. Abnormal wear also causes the gap between the drive cam and the hydraulic tappet to increase, the cam and the hydraulic tappet combination will occur when the impact, resulting in abnormal sound. Hydraulic Torque Wrench

The main reason is due to the structure of slender, working cam and tappet contact area is small, the unit pressure and the relative sliding speed caused by high. To test the bending of the camshaft, the front and rear journals of the shaft can be placed on a flat V-shaped iron plate, and then use the dial gauge to measure the displacement of the middle journal to determine.Hydraulic Torque Wrench
