The common faults of tire balancing machine mainly include the following aspects:
First, the display value error is large
Reason: Display value errors include Angle errors and amplitude errors, which are usually caused by a combination of factors. First, the balanced rotor itself may have problems, such as bending, poor assembly, and so on. Secondly, the instability of the speed of the balancing machine will also affect the accuracy of the measurement results. In addition, the sensor output signal instability, electrical measurement system components aging or temperature effects and other factors may also lead to increased errors.
Solution: For the problem of the rotor itself, it needs to be checked and corrected. For the situation of unstable speed, check whether the conveyor belt of the motor pulley is too loose, whether the belt is slipping, and tighten or replace the belt. At the same time, check the working state of the sensor to ensure that its output signal is stable. Re-calibrate the electrical measuring system if necessary.
Second, no speed or display speed change is too large
The reason:
1. If there is reflective paper or wire engraving on the balancing machine as the reference line for the photoelectric sensor to detect the speed signal, there will be no speed or excessive speed change because the engraving line is covered by dust or the reflective paper falls off.
2. The distance between the photoelectric sensor and the reflective paper is inappropriate and needs to be readjust.
3. Oil stains or rust on the end of the workpiece shaft may also cause inaccurate speed measurement.
Solution: Clean reflective paper or wire engraving to ensure that it is clearly visible. Adjust the distance between the photoelectric sensor and the reflective paper to the appropriate position. For oil or rust on the shaft end of the workpiece, it is necessary to clean.
Third, sensor failure
Cause: No output or unstable output of the sensor is a common cause of balance error. Sensor internal short circuit, connection rod bending or blocking, coil turn short circuit, etc., may lead to sensor failure.
Solution: Use a high-sensitivity multimeter to check whether the sensor output signal is normal. If the sensor has no output, check whether there is a short line inside the sensor, and repair or replace the sensor. If the output signal is unstable, check whether the sensor is loose or the coil turns are short circuit, and tighten or replace the sensor.
Fourth, the control module is faulty
Reason: The control module of the balancing machine is responsible for receiving and processing the sensor signal, and controlling the action of the actuator. If the chip in the control module is faulty or the electronic component is damaged, the display will display an error code (such as err1) or will not work properly.
Solution: Replace the new control module to restore the normal work of the balancing machine. During the replacement, select a model that is compatible with the original module, and ensure that the module is correctly installed and connected.
Fifth, mechanical component failure
Reason: The mechanical parts of the tire balancing machine, such as bearings, belts, transmission gears, etc., may fail during use due to wear, aging and other reasons. These faults will affect the measuring accuracy and stability of the balancing machine.
Solution: Regular inspection and maintenance of mechanical parts, timely replacement of severely worn parts. For wearing parts such as belts, they should be replaced regularly to ensure stable and reliable performance.
Sixth, power and environmental issues
Cause: External environmental factors such as power supply fluctuations, noise interference or ambient temperature changes may also affect the normal operation of the tire balancing machine.
Solution: Ensure that the power supply voltage used by the balancing machine is stable and meets the requirements of the equipment. When used in an environment with large noise interference, corresponding shielding measures should be taken. At the same time, ensure that the ambient temperature fluctuates within the permissible range of the device.
In summary, the common faults of the tire balancing machine involve many aspects, and need to be diagnosed and solved according to the specific situation. In the process of use, attention should be paid to regular inspection and maintenance of the equipment, timely detection and elimination of potential faults to ensure its normal operation.
