How to eliminate the abnormal condition of material testing machine and its method?

One, pull machine machine does not move

1. Check if there is any indication in the table. If not, check the power supply related parts, such as whether the wires, connectors, fuses, and switches are damaged.

2. Limit switch is turned on.

3, whether the emergency stop button pressed.

4. If the breakpoint stop function has left the setting.

5, wiring line failure, magnetic field voltage.

Second, tensile testing machine machine Taiwan plate can only one-way operation

1、Limit upper and lower limit switches are abnormal, stuck or damaged or contact errors are loose

2. Whether the operation button function is lack of lubrication oil, it should be replaced and supplemented.

3, electromagnetic switch is damaged.

Third, the tension machine machine operation is normal but the flow meter indicates abnormally large or large abnormal changes.

1. Please check whether the power board is tilted or out of position. The torque of the transmission is not normal. The nut should be adjusted so that the parallel board and the table can be adjusted in parallel. Attention should be paid to whether the condition of the screw and the nut is damaged and whether the tightness adjustment is appropriate.

2. Find out if the motor is running normally, load condition and no-load condition (remove chain or belt running).

3, find out whether the bearing is normal.

Fourth, the tension machine machine transmission is normal but there are different sounds

1, the screw is not lubrication, lubrication should not be smooth.

2. If the gear reducer lacks lubrication oil, it should be replaced and replaced.

3. If the belt or chain is loose, adjust it and the chain should be lubricated.

4. If the motor and control parameters are set as normal, they should be adjusted and set.

V. Rally speed cannot be set or controlled

1. The control substrate potential trimming resistor is damaged.

2. The control circuit fuse is blown, replace and check if the transformer and the secondary load current are overloaded.

3, control setpoint is not normal, resulting in loss of control.

Note: Each time the drive system and servo control system is turned off/on, it needs to be separated by at least 15 seconds. Otherwise, it is easy to cause the drive controller to crash and generate an abnormal signal.
