At present, many users usually reflect the use of bourns potentiometers, and there are often some rotation noises during operation adjustments, so that many novice technicians later misled the potentiometers as a problem, and chose to replace the bourns potential. Device. In fact, the potentiometer is a small problem that can be dealt with for some of the adjustment noises that occur. It is not necessary to replace the component every time a small fault occurs, which will undoubtedly cause a failure. Necessary product wear status. So today, I will mainly talk about how to eliminate the noise of bourns potentiometer adjustment and share some common knowledge about related operations. I hope it can help you.
How to eliminate bourns potentiometer adjustment noise
Method 1 for eliminating adjustment noise
Secondly, for the noise caused by the rotation of the bourns potentiometer, on the other hand, there may be debris or excessive dust in the carbon membrane inside the potentiometer. And with the passage of time, the daily operation of its potentiometer will invade and absorb certain dust and debris. So how do you generally solve this kind of regulation noise failure?
Steps:
First, you need to disassemble the bourns potentiometer and use some small brushes to indicate that some dust and debris are removed. The rear needs to be stained with alcohol to clean it thoroughly, because if there is no alcohol, there will be some small debris adsorbed. And dust on the surface is difficult to clean. However, you need to pay attention to the rear position. After cleaning the debris of the potentiometer, you need to blow the components inside the bourns potentiometer or use a hair dryer to remove the water vapor, because after all, alcohol is a liquid, if you do n’t pay attention to the rear, Therefore, it is also easy to induce the damping of the potentiometer's components.
Method 2 for eliminating adjustment noise
Generally, the bourns potentiometer often emits some noise during operation adjustment. In fact, there may be a failure in the internal shaft component of the potentiometer. It is usually necessary to disassemble it to check whether the internal component of the potentiometer is damaged or not. The damage to the found rotating shaft components may cause problems such as oxidative corrosion that affect other components and cause noise. Therefore, this is generally difficult to maintain. In this case, it is recommended to directly replace the new bourns potentiometer application.
Bourns potentiometer operation tips
1. The bourns potentiometer is generally used for a long time, and related maintenance and cleaning work needs to be performed regularly. For example, the surface of the carbon sheet of the potentiometer should not be attached with too many foreign objects, such as dust or debris. Otherwise, it may cause bourns potentiometer When the internal brush momentarily disconnects the contact with the carbon sheet, the postposition causes the brush of the potentiometer to deform, resulting in poor contact with the carbon sheet and causing some adjustment noise problems. Therefore, after the potentiometer is usually used for three months, it needs to be cleaned and maintained accordingly.
2. Regarding the detection of faults in the bourns potentiometer, please be careful not to disconnect the wires on each end of the potentiometer, because if you want to detect the fault of the line, you can usually directly connect the lead of the potentiometer. It is not necessary to disassemble the connection point to measure on the foot contact. Otherwise, once the connection is disconnected, the rear needs to be re-welded. It is the rear that is careful not to pull the wiring on the potentiometer pins, so as not to break the other wiring of the motherboard.
Secondly, after the completion of each installation step, bourns potentiometer should pay attention to that it cannot be applied to use immediately, and it is also necessary to carry out safe hidden danger detection, for example, check whether the pins of the potentiometer are connected to each other. In this case, whether the substrate of the bourns potentiometer has some cracks or breakage, or these minor problems directly affect the performance of the potentiometer. In general, once a failure occurs, if it is not a relevant technical person, it is recommended not to operate it indiscriminately, because there are many points of attention to maintenance technical work that we ca n’t ensure proper operation. Once the operation of some problems is not correct, it may cause deterioration and increase the difficulty of secondary maintenance.
