|1||Actions failure||1.Wrong or loose electricwiring|
2.Pressure of controloiltank not sufficient
3.Insufficient oil in oiltank.
|1.Check the wireconnecting|
2.Regulate the pressure to 1.5Мра
3.Add oil to the required level
|2||Slide creeping||1.There is air in the hydraulic system or thesuction port of the oil pump sucks air |
2.The accuracy is not fitor the vertical columnislack of lubricate oil.
|1.Check the suck pipe of the pump and make the slide move up and down several times then pressurized.|
2.Readjust the accuracy and fill the lubricate oil to vertical columns.
|3||When the slide moves down slowly, upper chamber of the main cylinder have pressure||Over high supportpressure||Adjust the counterbalance valve to make upper chamber of the main cylinder pressure free, the pressure should be less than 1MPa.|
|4||Machine stop but slide keep downing||1. Cylinder leaking|
2. Pressure valueleaking
|1. Change seal when cylinder leaking|
2. Adjust value pressure
|5||Pressure gauge pointer swing||1. Air in pressuregauge|
2. Pipe mechanicalshocking
3. Press gauge broke
|1. Release air in pressure gauge|
2. Fixed pipe
3. Change one new press gauge
