Wear Symptom Of Hydraulic Torque Wrench

High-power hydraulic torque wrench is a part of the piston engine. Its function is to control the opening and closing action of the valve. Generally speaking, in a straight-line engine, a cam corresponds to a valve, a V-type engine, or a horizontal-pair engine that shares a cam per two valves. The rotor engine and the valveless valve engine have no need of Cam because of their special structure. The common faults of the camshaft include abnormal wear and tear, abnormal noise and rupture, often preceded by unusual wear symptoms.Hydraulic Torque Wrench

In some cases, the failure of the camshaft is caused by man-made causes, especially when the engine is repaired without proper disassembly of the camshaft. For example, the removal of camshaft bearing cover with a strong hammer or a screwdriver to pry, or install the bearing cover when the position is wrong to cause the bearing cover and the bearing seat mismatch, or bearing cover fastening bolts tightening torque too large. The camshaft is located almost at the end of the engine lubrication system, so the lubrication condition is not optimistic. If the oil pump because of the use of too long and other reasons for the lack of fuel pressure, or lubricating oil road blockage caused by lubricating oil can not reach the camshaft, or the bearing cover fastening bolts tightening torque too big cause lubricating oil can not enter the camshaft gap, will cause abnormal wear of the camshaft.Hydraulic Torque Wrench

High speed. To test the curvature of the camshaft, the front and rear axle neck of the shaft can be placed on a V-shaped iron with a flat plate, and then the dial is used to measure the pendulum difference of the intermediate axle neck. When the allowable value is exceeded, the cold pressure correction should be performed. The test of CAM wear is to measure the distance between the top center of the cam and the diameter of the base circle with the micrometer, and to determine its wear degree by the difference between the two, which should be greater than 8 mm.Hydraulic Torque Wrench
