How to Maintain Frequency Converter Life?

Long-time use of frequency converter will lead to lower quality and efficiency, resulting in a serious impact on the equipment. So we not only need to regularly replace the spare parts of the frequency converter but also need to know the correct way of replacement, in this way we are able to ensure the quality and service life. Now we will introduce you to the replacing method of frequency converter spare parts.

Filter Capacitor

A filter capacitor is also known as an electrolytic capacitor, which is mainly used to absorb low-frequency harmonics in the DC power supply, in order to smooth DC voltage. If the filter capacitor continuous operation for a long time, the heat generated will let the electrolyte dry faster, affecting the capacity. The filter capacitor life under normal circumstances is five years. If you want to effectively guarantee the frequency converter service life, it is recommended to periodically check once a year. Generally, if the capacity reduction is more than 20%, it will need to be replaced.

Cooling Fan

The power supply module is the most severe heating device in a frequency converter. It must promptly and continuously discharge the heat to avoid being damaged. Generally, the service life of the cooling fan is about 10Kh-40K, that is to say, under continuous operation, the fan needs to be replaced beyond two to three years. The fan voltage is generally 220V or 380V, pay attention to replacing the correct one. The cooling fan has 2 or 3 tiers, the 2 tier fan line is positive and negative, do not connect wrong in replacement; 3 tier fan has one more detect line, pay attention to avoid overheating the alarm when replacing.

The frequency converter has a variety of components, some of the components will have inevitably age after prolonged use, performance will also diminish, and it will lead to variable glitches. So when we use the frequency converter, in addition to necessary maintenance work, regular inspection replacement works it is also very important and very necessary.
