Common faults and solutions of pulse dust collectors

The common faults and their solutions of pulse dust collectors include the following:

Good sales, incorrect differential pressure reading: This may be due to cleaning the pressure tap and checking for cracks or differential pressure gauges in the pipeline. The solution includes inspecting and cleaning the pressure tap to confirm that there are no cracks in the pipeline, and calibrating the differential pressure gauge.

Excellent, incorrect setting of the blowing system: Excessive blowing frequency or low compressed air pressure can lead to poor blowing effect. The solution includes adjusting the blowing frequency, checking the compressed air supply system, and confirming that the pressure meets the requirements.

Blowing valve malfunction: It may be caused by a malfunction of the diaphragm valve or control solenoid valve. The solution includes checking and replacing the faulty diaphragm valve or control solenoid valve.

Filter bag blockage: Filter bag condensation or dust accumulation can cause blockage. The solution includes drying the filter bag, increasing the frequency of dust cleaning, or replacing the filter bag.

Fifth, excessive dust concentration emissions may be caused by damaged filter bags, large pores, or improper installation. The solution includes regular inspection and replacement of damaged filter bags, adjusting the relationship between filter bag pores and usage time.

Sixth, excessive resistance of the dust collector: may be caused by filter bag blockage, dust removal system failure, or blockage of inlet and outlet pipelines. The solution includes optimizing dust removal methods, clearing pipeline blockages, and ensuring smooth airflow.

Pulse valve failure: It may be due to power failure, insufficient compressed air pressure, or damage to internal components of the pulse valve. The solution includes checking the power supply and compressed air supply system, replacing damaged parts, and regular maintenance.

Severe fan wear: It may be caused by excessive dust or improper fan handling. The solution includes checking and replacing the appropriate fan to confirm that it is suitable for the working conditions.

Filter bag damage: It may be caused by high-temperature flue gas corrosion, mechanical wear, or chemical corrosion. The solutions include reducing the temperature of the flue gas, increasing the heat resistance of the filter bag material, or adding pre-treatment equipment.
