Electrical faults on the printing machinery mainly occur in the electronic components on the motor and control circuit. In the case of motors, different methods of measurement are used for motors of different power levels using a temperature rise method.
Such as small and medium-power motors can be used touch touch method and finger sticking method these simple methods to measure. In order to prevent electric shock, it is best to use the back of the motor to touch the housing of the motor. If you feel hot and not hot, the motor is not overheated.
Generally about 40 °C, feel hot without hot, such as feel hot (about 60 °C or so), you should consider whether the stability of the three-terminal regulator has been abnormal. If you touch the diode and triode, you can use a multimeter to measure it. Feeling hot without burning sensation indicates normality. If the burning sensation is strong or there is no thermal sensation, it indicates that the performance of the tube is degraded or completely damaged.
With a multimeter to judge, put the table to R * I00 or R * I000 file, but not R * I file (the file measurement error).
During the measurement, the two electrodes of the red and black meter rods and the diodes are used to switch between two poles. If the measured forward and reverse resistances differ greatly, the reverse resistance approaches infinity, indicating that everything is normal. The performance declines or can not adapt to its working environment temperature. Generally, the maximum dissipation power of the diode decreases by 1%-2% for every 1°C increase, so its operating environment temperature is generally controlled below 50°C.
For the triode, first use the temperature rise method to make a simple measurement, whether there is a hot smell, if there is a feeling of hot, then use a multimeter to test. If the measured positive resistance of the emitter junction is too large, it indicates that the tube is open circuited. If the reverse resistance is too small, the stability of the tube will be worse. However, it should be noted that when measuring, the type of the pipe is different, and the forward and reverse resistances are also different. Therefore, the model of the pipe must be clearly observed during measurement to avoid misjudgment.
For low-power diodes, transistors, resistors, capacitors and other electronic components, due to low power, the resulting temperature rise is also low, in the measurement of the first finger card temperature (that is, with the thumb and the food phase to be measured components). After repeated measurements, repeated comparisons, such as a touch of tepid or slightly hot, indicate normal, such as a strong sense of heat, should be considered whether due to excessively high ambient temperature or humidity caused by, and then use a multimeter to make the final judgment, must not be sick Work, so as not to affect the normal operation of the entire control circuit.
