Self-cleaning air filter common faults and solutions

Self-cleaning air filter common faults and solutions

Self-cleaning air filter is a new type of air filter with automatic dust cleaning function, especially suitable for long-term, continuous air purification of gas equipment in sandstorm prone conditions. However, in the use of the process will also encounter some problems, the following to give you a summary of some common faults and solutions, together to a simple understanding of it!

1. The power supply is connected, but there is no display on the panel of the controller

Check whether the air switch in the controller is closed.

2. The power supply is connected, but the filter does not work

1) Please confirm that the compressed air is connected.

2) Please confirm that there is no air leakage in the compressed air pipeline.

3) There is too much dust and impurities in the oil-water separator, which causes air leakage and filter element blockage in the oil-water separator. Please remove and clean it.

4) A group or several groups of solenoid valve leakage, so that the compressed air in the air storage tank loss, please replace the diaphragm of the solenoid valve.

5) The main circuit board is damaged.

6) The branch circuit board is damaged.

3. A solenoid valve does not act

1) The solenoid valve coil of the group is burned out.

2) The solenoid valve is blocked, disassemble and clean.

3) The electronic components in the circuit board corresponding to the group of solenoid valves are burned.

4. The resistance displayed on the electronic control instrument is zero

1) Please confirm that the fan (compressor) is running normally.

2) There are two probes on the differential pressure sensor in the electronic control instrument, one directly to the natural air; The other shall be connected to the negative pressure probe of the clean gas chamber. Connect the plastic pipe from the clean gas chamber to the differential pressure sensor to this position.

The above are some common problems in the use of the self-cleaning air filter. If you encounter these problems in the use of the filter, I hope it can help you.
