The frequency converter is a kind of electric energy controller. In many industrial equipment, the frequency converter can save energy and save electricity. Frequency converter in the use of the process is also the need for dust, then what is the specific method of dust prevention? The following small editor to introduce the method of frequency converter dust proof.
1, the design of a special frequency converter room:
When the frequency converter uses a large number of power or more, a special converter room can be designed. The doors and windows of the room and the cable through the wall hole require sealing to prevent dust from invading. We should design the air filter and circulation channel to keep the indoor air in normal circulation, and ensure the indoor temperature below 40 C. Unified management is conducive to inspection and maintenance.
2. The converter is installed in a cabinet with a fan and a filter device.
When the user has no conditions to set up a special frequency converter room, you can consider making a inverter dustproof cabinet. The design of the fan and filter to ensure sufficient air flow in the cabinet. The user should check the fan regularly, remove the dust on the filter network, and prevent the increase of temperature over the prescribed value because of insufficient ventilation.
3, the use of strong dustproof frequency converter:
There are many specifications and models of the frequency converter on the market. In addition to the price and performance, the frequency converter should also consider the adaptability of the frequency converter to the environment. Some inverter no cooling fan, the shell in the air natural cooling, compared with air-cooled inverter, although larger, but the device has good sealing performance, not affected by dust, easy maintenance, low failure rate, long service life, especially suitable for corrosive gas and dust industry applications.
4. Reduce the idle running time of the frequency converter:
The general inverter is usually connected to the power supply in the industrial production process. It controls the starting / stopping and rotation direction of the motor through the positive / negative / common terminal control terminals of the converter or the buttons on the control panel. Some equipment may be in time to stop, the fan is still running when the inverter is no-load, and it will absorb dust, which is not necessary. In the process of production operation, the idle time of frequency converter should be reduced as far as possible in order to reduce the influence of dust on the frequency converter.
5, set up regular dust removal system:
The user should determine the time interval of regular dust removal according to the influence of dust on the frequency converter. The dust can be swept by electric vacuum cleaner or compressed air. After the dust removal, we should also pay attention to check the rotation of the inverter fan, check whether the electrical connection point is loose and hot.
