What are the maintenance methods for the failure of audio taper potentiometer?

The audio taper potentiometer, as its name implies, is used to regulate the volume of potentiometer, widely used, such as daily household speakers and audio and other electronic products are required to use potentiometers to operate to regulate the volume. If the operation is improper, it is easy to break down. Here are some troubleshooting methods for the audio potentiometer with switch potentiometer manufacturer.

1. About the hoarseness and disorder of the alps audio potentiometer in operation and regulation, it is usually caused by bad contact problems caused by dust and sundries inside the potentiometer. Its maintenance methods generally need to first remove the potentiometer, dust and debris, which can eliminate noise and other faults.

Secondly, there is another kind of fault, that is, the audio taper potentiometer usually has some noise condition, which is caused by the friction between the internal handle of the potentiometer and the carbon plate. In order to deal with this kind of noise, it is necessary to drop some lubricating oil directly into the adjusting shaft of the potentiometer and rotate it several times, so as to effectively eliminate the problem of this noise.

3. The alps audio potentiometer has some regulation failure and no response to the use of the situation, which is usually the internal handle of the potentiometer may be damaged, as long as it replaces a rotating shaft. However, there will be another situation, that is, it is possible that other components of the potentiometer are damaged, which is difficult to repair, so it is generally recommended that only the potentiometer be replaced.

4. The audio taper potentiometer usually have the problem of producing abnormal sound, that is, either the sound adjustment is too small or the sound is too loud. Generally, it is possible that the resistance method of potentiometer has been changed, because if the resistance is not compatible with the operation of the channel line, it will lead to abnormal conditions of these regulated sounds, and if serious, it will also cause the potentiometer to turn off some sounds. Therefore, in general, the resistance of potentiometers should not be changed casually.

5. There is also a alps audio potentiometer in general use do not wet hands to operate and adjust, or if the potentiometer axis of water and gas intrusion, it will lead to short-circuit potentiometer situation, resulting in the potentiometer can not be used normally. So generally for the use of potentiometers do not wet hands to operate, and in the humid environment to use, but also pay attention to the moistureproof work of potentiometers.

What are the harmful phenomena of bad potentiometer

In our life, we often come into contact with potentiometers. Especially in recent years, it develops rapidly and is used more and more in our life and industry. However, what good products we need to identify carefully. Because of the uneven production level of potentiometer manufacturers in the current industry, many bad products will appear. What are the common adverse phenomena of bad potentiometers? The specific contents are as follows:

1. No output or monophonic channel
The main reason is that brush deformation causes contact INT, carbon sheet wiring to be artificially scratched or contact loosening caused by terminal soldering.

2. Poor murmur
The main reasons are brush deformation, rough carbon surface with coarse particles, dirty surface, customer circuit power, breakdown, track mismatch, etc.

3. Functional failure of products after soldering
Products can not be soldered by soldering process or customers in the selection of errors, such as ordinary materials through wave soldering, POM plastic materials used by us are prone to deformation, resin plate riveting terminals are prone to loosening, resulting in product failure; therefore, it is recommended to use glass fibre board material.
