What are the common faults and solutions of dust collectors in Dalian?

As a key equipment for industrial production and environmental purification, Dalian dust collectors may encounter various malfunctions during operation. Understanding these common faults and their solutions is important for maintaining their efficient and stable operation.

Firstly, damaged filter bags are a common issue. This may be due to poor quality of the filter bag, long-term erosion and wear from dust, or improper cleaning methods. For example, when dealing with high hardness and high concentration dust, if the cleaning pressure is too high or the frequency is too fast, the filter bag is easily worn and broken. The solution is to choose filter bags with reliable quality and strong wear resistance, and adjust the cleaning parameters reasonably according to the characteristics of the dust, such as reducing the pressure of pulse blowing or extending the cleaning cycle appropriately. At the same time, regularly check the condition of the filter bags and replace damaged ones in a timely manner.

Secondly, fan failures also occur from time to time. Excessive vibration of the fan may be due to unbalanced impeller, worn bearings, or loose foundation bolts. When uneven dust deposits adhere to the impeller, it can cause the impeller to become unbalanced. At this point, it is necessary to clean and dynamically balance the impeller, replace worn bearings, and tighten the foundation bolts. In addition, motor overload of the fan may be caused by pipeline blockage, improper fan selection, or unstable voltage. Ventilation ducts should be inspected and cleaned to ensure smooth airflow; Verify whether the fan selection meets the actual working conditions requirements; Install a voltage regulator to stabilize the voltage and prevent motor overload and burnout.

Furthermore, blockage of the ash hopper is also a common malfunction. High dust humidity, malfunction of the unloading device, or unreasonable design of the ash hopper may all cause this problem. For dust with high humidity, heating devices or vibrators can be installed in the ash hopper to prevent dust from clumping and accumulating. Check the unloading device, such as whether the star shaped unloader is stuck or damaged, and repair or replace it in a timely manner. At the same time, optimize the design of the ash hopper, such as increasing the inclination angle, to make it easier to discharge dust.

In addition, the malfunction of the dust cleaning system cannot be ignored. Pulse valve failure, insufficient pressure of the dust cleaning gas source, or blockage of the spray pipe can all affect the dust cleaning effect. Regularly inspect the diaphragm and solenoid valve of the pulse valve to ensure their normal operation; Check the gas source equipment, such as air compressors, to ensure stable gas supply pressure; Clean the debris inside the spray pipe to ensure smooth airflow.

In short, by strengthening daily inspections and maintenance, timely detection and resolution of common faults in Dalian dust collectors can ensure their stable operation, effectively play the role of dust removal, and provide strong guarantees for the purification of production and atmospheric environments.
