Nowadays, the multihead weigher table is generally in the condition of all normal applications, and it is not easy to see which common faults and which common faults occur. But if you don't pay attention, the general experimental instruments are not used in accordance with the application standard of the electronic product multihead weigher table, then the electronic product multihead weigher table will appear aging over time. The specific manifestations of electronic weighing multihead weigher aging can be divided into three categories.
One is the aging of the power plugs of all mechanical equipment at room temperature. Second, the high temperature overall mechanical equipment is energized and aging. The third is to simulate the aging of high-temperature full-band simulation load.
The aging of the entire mechanical power plug at room temperature can be summed up as a complete SPWM, which is not too easy to cause damage. It is because the equipment has been used for a long time, and then it is justifiably aging. In addition, the energization of all mechanical equipment at high temperature simulates the aging of the load of all mechanical equipment at high temperature. These two conditions are all attributed to the amount of current, and the geographical environment of the installation is excessively extreme. Therefore, it will cause the aging of the dashboard in the car. What should I do after the aging of the multihead weigher table of electronic products? The following are the solutions that have been obtained: 1. The number of the multihead weigher table is unstable; because the power capacitors C4 (CBB474) and N8 (4011) cause poor contact or even damage due to moisture or other reasons, so the number is not stable, then it can be Try to carry out repair welding or disassembly.
2. The self-check multihead weigher is not zeroed; sometimes after zeroing, the range of vibration is automatically changed, and it is zeroed along with a part, so that the error is very large after the lifting is unbalanced, and it will continue to be The zero point after the hoisting school abandonment indicates a negative information content. 3. After the multihead weigher is turned on, the weighing fails. When all the normal settings cannot be set, press“reset to zero”Press the key to start and then set the detection range again. After restarting, the detection range cannot be set. Most of them can be identified as the data storage N7 (24C04) is damaged. After disassembly, set the detection range again, and be sure to calibrate again. Therefore, no matter what kind of electronic product causes the aging of the multihead weigher dial of the instrument panel, it is necessary to improve and prevent it in advance.
It's not useful unless it's before the in-vehicle dashboards of the electronics multihead weigher dial are in a condition of significant ductility for long periods of time. Therefore, the best way is to pay more attention to maintenance when using electronic scales, inspect the parts, and ensure that all parts can be used normally, so as to ensure that the electronic scales are not prone to aging in the second half of the period. .
