1. Percussion hand pressing When we use the instrument, we often encounter the phenomenon of good and bad operation of the instrument. Most of the phenomena are caused by poor contact or false welding. For this case, the method of percussion and hand pressure can be used. The so-called "knock" is to knock the plug-in board or component gently through a small rubber hammer or other knock object to see if there is any error or shutdown failure. The so-called "hand pressure" is to press the inserted parts and plugs and seats firmly with hands when the fault occurs, and then turn on the power to try whether the fault will be eliminated. If it is found that the shell is normal and then the beating is abnormal, it is better to plug all the connectors firmly and try again. If it is not successful, we have to think about other methods.
Common faults: the sensitivity of dial indicator is poor, there is a stoppage phenomenon after unloading, or the zero position often changes. There are many reasons for this phenomenon. When loading a load, sometimes the maximum load is not added or unloaded during the loading process. Such faults often occur and cause more.
1. When the computer software is online, the prompt box will appear and the information will be overloaded. Exclusion method: Check whether the communication line between the computer and the testing machine falls off; Check whether the online selection sensor is selected correctly; Check whether the sensor has been hit during the recent test or keyboard operation; Check whether the software calibration or calibration function is used before the problem occurs; Check that calibration values, calibration values, or other information in hardware parameters have been manually changed. 2. The main power supply of the testing machine is not on, and the equipment cannot move up and down. Exclusion method: Check whether the power line connected to the testing machine is connected normally; Check whether the emergency stop switch is turned up; Check whether the power supply voltage connected to the testing machine is normal; Check whether the fuse on the socket of the machine is burnt out. Please take out the spare fuse and install it. 3. The main power supply of the testing machine has power, and the equipment cannot move up and down. Exclusion method: Check whether the device can't move after 15s, because the host needs self-test when starting up, which takes about 15s; Check whether the upper and lower limits are in the right position and there is a certain operating space; Check whether the power supply voltage connected to the testing machine is normal.
1. The prompt box appears after the computer is online, indicating overload Exclusion method: Check whether the communication line between computer and tester falls off; check whether the online selection sensor is selected correctly; check whether the sensor has been hit during the latest test or keyboard operation; check whether calibration or calibration function was used before the problem; check whether calibration value, calibration value or other information in hardware parameters have been changed manually 2. The main engine power supply of the test machine is not on, and the equipment cannot move up and down Exclusion method: Check whether the power line connected to the tester is connected normally; check whether the emergency stop switch is in the state of being screwed up; check whether the power voltage connected to the tester is normal; check whether the fuse on the machine socket is burnt out, please take out the spare fuse and install it 3. The main engine power supply of the test machine is powered, and the equipment cannot move up and down Exclusion method: Check whether the equipment can not be moved after 15s, because the host needs self inspection after starting, which takes about 15s; check whether the upper and lower limit position are in proper position and there is certain operating space; check whether the power voltage connected to the test machine is normal
After using for a period of time, the box compression testing machine is prone to large and small failures, which affect the daily operation. Many users are very confused about this. In order to further solve the needs of users, Kunshan Haida Xiaobian has made a brief introduction on the common faults of the compression testing machine. The specific contents are as follows:
The high and low temperature test box shall be maintained regularly, the condenser of refrigeration system shall be cleaned regularly, and the moving parts shall be lubricated according to the instructions, and the electrical control system shall be regularly maintained and inspected, etc. these work is necessary.
