See more problem of tee machine hydraulic cylinder
1:Lack of tee machine cylinder thrust load when the cylinder is not action.To do the following experiments: in reversing valve cylinder empty load operation, if the oil cylinder to the mountain of elasticity, and sometimes extended and retracted speed is faster than normal, to be able to conclude that the oil cylinder.Because the oil cylinder into the impurities or iron piston severe damage on the oil seal and bearing ring, make the oil cylinder rod cavity and rodless cavity connected, constitutes the differential circuit.
2:Hydraulic tee machine oil cylinder except for connecting tubing and tubing o-rings damage caused by the external leakage, internal leakage caused by the cylinder head and piston rod seal failure is also compared to see more.
3: Cylinder, hydraulic tee machine cylinder cylinder is mainly due to excessive wear ring between the piston and cylinder wear after directly touch the piston and cylinder, piston hardness hardness is greater than the cylinder, piston will cutting cylinder and the cylinder.Cylinder, hydraulic cylinder rise and drop all weakness, cylinder, severe cylinder that is invalid.
4: deformation, deformation is mainly the hydraulic cylinder,hydraulic cylinder impact due to external forces or the load is overweight.
5:damage of the hydraulic tee machine cylinder piston rod, such as the piston rod is scratched or piston rod outside appearance with hollow cavity is same. |
