Frequency conversion air compressor maintenance must not do this

Compared with industrial frequency air compressors, the advantages of variable frequency air compressors are, for example, that variable frequency air compressors operate at constant pressure, without no-load, and energy efficiency is greatly improved. For most air compressor users, variable frequency air compressors are indeed energy saving. The frequency conversion air compressor can also meet the user’s demand for fluctuating gas consumption in peak production seasons and off-seasons. In addition, the soft start of the frequency conversion air compressor can also reduce the load on the user’s power grid. When the frequency conversion air compressor and the power frequency air compressor are changed due to technical changes such as design and operation, the maintenance and maintenance requirements of the frequency conversion air compressor are much higher than that of the power frequency air compressor, and the maintenance is still in accordance with the requirements of the power frequency air compressor 1. Maintain the frequency conversion air compressor, resulting in a high failure rate of the frequency conversion air compressor.

1. The frequency conversion air compressor is easy to accumulate water when the frequency is low, and the water resistance requirement of the lubricating oil is much higher than that of the power frequency air compressor.

2. The power frequency air compressor can be divided into loading and unloading. The frequency conversion air compressor is always in the loading state. For the same running time, the loading time of the frequency conversion air compressor is much higher than that of the power frequency air compressor. The compressor runs for 2000 hours, which is equivalent to the power frequency air compressor running for 2500-3000 hours, or even more;

3.Generally speaking, the operating temperature of the frequency conversion air compressor is higher than that of the power frequency air compressor, so the temperature resistance of the lubricating oil is much higher than that of the power frequency air compressor. To put it simply, for the same type of air compressor, the requirements for the quality of lubricating oil for variable frequency air compressors are 1-2 grades higher than those for industrial frequency air compressors. Therefore, the variable frequency air compressor should use high-quality lubricating oil that is 1-2 grades higher than that of the industrial frequency air compressor. Therefore, when choosing an inverter air compressor, these factors must be considered. Do not maintain at a low price and seek cheapness. It is a direct and effective method to compare the operating current in the middle and later stages of the maintenance cycle.
