Seven, fault and solution method:

A, tensile test machine, vibration or pause the pointer
1, the clutch gear wear: the need for repair or replacement.
2, the skin friction disc washer or spring wear: need to change the skin or spring washer.
3, handle shift: to adjust the control handle, make it fit in with the alveolar.

Two, the replacement of pendulum weight when the pointer does not return to zero
1, tensile testing machine installation is not level: the level to adjust the level of test machine.
2, not only the vertical pendulum hanging weight: A. Adjust the balance weight, so that the vertical.

Three, tensile testing machine, the pendulum back a bit too fast or too slow
1, the buffer valve gear position placed improper: adjust the buffer valve to the appropriate location.
2, the hydraulic oil viscosity is too low or too high: hammer down fast swing hydraulic oil viscosity is too low, viscosity is high down slowly. Should be proper replacement of hydraulic oil viscosity.
Vittae 3, buffer valve, or hydraulic oil dirty: washing buffer valve, pipe. Replacement of hydraulic oil.

Four, tensile testing machine pointer back to zero lag or unstable
1, the pointer bearing, spindle bearing corrosion or oil: clean or replace bearing.

Six, showing the value of negative deviation is the main reason of the frictional resistance between the units is too large

1, the pointer shaft bearing, bearing and power transmission parts friction resistance is too large: mainly adjustment, cleaning bearings and force transmission parts to eliminate the friction resistance is not normal.
Friction resistance on 2, chuck, driven needle leaf spring tightness and describe the adjustment device: chuck, driven needle leaf spring tightness and drawing device components. To eliminate the friction resistance is not normal.
3, the piston rod and the swing rod is connected with the flexible adjustment of both parts not connected parts. The flexible.

Seven, the driven needle stagnation or shift
Effect of 1, driven needle leaf spring elastic force or driven needle and dial friction resistance caused by the gap adjustment driven needle: the elasticity of the spring piece or driven needle and dial.
2, the driven needle are heavy alligator deviation: adjusting the weights, the balance.

Eight, showing the value of deviation is irregular

The solution is to check the computer and test machine communication line is off; check the online selection of sensor is correct; check the last test or operation keys
When the sensor is knocked off; check whether the use of a software appears calibration or calibration before; check whether the manual modified calibration values, calibration information value or other hardware parameters in the.
Host ten, the power of the testing machine does not light, not to move up and down.
The solution is power line inspection access testing machine is connected properly; check the emergency stop switch is in screwed up state; power supply voltage check access testing machine is normal; check the socket on the insurance is burned off, remove the spare fuse can be installed.
Host eleven, testing machine power supply with power but the equipment can not move up and down.
The solution is to check whether it is 15S （time） after the device is unable to move, because the host boot take self-inspection, probably need 15S time; check the upper and lower limit is again appropriate position, operating space; check supply voltage access testing machine is normal.

Eight, oil source:
1, regularly check the host and the supply of oil leaks place, if there is oil leakage, should be promptly replaced seal ring or a combined pad;
2, according to the use condition and oil machine use period, replace the oil filter and filter periodically, replacing the hydraulic oil.
Experiment 3, not long time, pay attention to shut off the main power. If the machine is in the standby state, the switch should call the "load" file, because if the switch on the "rewind" file, electromagnetic reversing valve has been in a power-on state, affect the service life of the device.

Nine, control system maintenance:
1, regularly check the controller panel connecting line is good contact, such as loose, should be timely fastening;
2, after the test if there is a long time not machine closed, controller and computer;
3, the controller interface for the corresponding one one, inserted the wrong interface may cause damage to the equipment;
4, Swap Controller Interface must be shut down the power supply controller.
