Frequency converter is a kind of power control equipment which uses frequency conversion technology and microelectronics technology to control AC motor by changing the frequency mode of motor power supply. Its use not only enables the motor to achieve more efficient operation, but also ensures the controllability of motor working conditions, which is very important in modern industry. But in the process of using frequency converter, there is a headache that is dust and dust removal, so how to do? Today, Xiaohui will teach you a few moves.

1. Operation stage: reduce the no-load running time of the frequency converter

Generally speaking, in the production process, the inverter controls the start stop and rotation direction of the motor through the "forward / reverse / common end" control terminal or the key on the control panel. However, some equipment will be on and off from time to time, but the fan still keeps running when the frequency converter is empty, which will absorb a lot of dust. Therefore, users should try to reduce the no-load time of the frequency converter and reduce the impact of dust on the frequency converter.

2. Installation stage: install the frequency converter in the cabinet with fan and filter device, or provide special inverter room for frequency converter

Frequency converter has certain requirements for the use of the environment, installation requires good ventilation conditions, the environment should not have too much corrosive gas and dust. In order to improve the service life of frequency converter, users can consider making inverter dust cabinet, and ensure enough air flow during design. Of course, the regular inspection of the fan is indispensable. The dust on the filter screen should be removed in time to prevent the temperature increase due to insufficient ventilation.

If the power or quantity of frequency converters used is large, a special inverter room can be considered if conditions permit. The doors and windows of the special inverter room and the cable through the wall holes should be sealed; at the same time, the design of air filtering device and circulation channel should be considered, so that the indoor air can be normal circulation.

3. Habit formation stage: develop the habit of regular dust removal

The frequency converter needs to be cleaned regularly. Once it is not cleaned for a long time, it is easy to accumulate dust, resulting in equipment blockage and slow operation. Therefore, it is necessary to deal with these dust in a timely manner. It is better for users to form the habit of regular dust removal according to the working environment of frequency converter. Electric vacuum cleaner or compressed air can be used for cleaning.
