Hydraulic cylinder troubleshooting

Not normal circumstances causes Countermeasures
The piston does not stop operation to examine whether it belongs to the normal operation of hydraulic system in hydraulic system
The piston is not actuated pipeline connection error to confirm all the lines are connected properly
The piston is not actuated hydraulic pump direction error in operation in the test steps to correct
Hydraulic cylinder thrust under pressure is not in the normal means of a pressure gauge on the hydraulic cylinder into the oil inlet
Hydraulic cylinder thrust is not enough pressure oil return pipe is too high or the amount of oil leak more than the normal value of O type ring damage caused, replace the O ring
Hydraulic cylinder thrust is not enough oil inlet filter blocking the impurity cleaning the filter and oil tank, replace hydraulic oil
