What to do if air filter has poor filtering effect

Compressed air can be used in many ways as an energy source. B. Driving motors, painting, controlling machines and drives, etc. Like plastics processing, compressed air is essential to countless processes in the chemical industry. Good quality compressed air certainly improves the process, but compressed air with substandard contaminants slows down the production process and affects product quality. DPC compressed air filters can remove 99.99% of liquid water, oil, dust, particulates and other contaminants in compressed air.

 

In fact, there may still be many impurities in the air up to the compressed air filter, making the compressed air filter less effective, why? We should analyze and solve the problem of poor filtration effect from the following aspects.

 

1, the inlet air is not pretreated, additional pre-filter;

 

2, the downstream pipeline is not clean, flush the downstream pipeline;

 

3, the cartridge fastening screw is not tightened, tighten the cartridge;

 

4, the flow rate exceeds the rated value, replace the high-flow filter;

 

5, there is airflow short circuit inside the filter, find the cause and deal with the problem;

 

6, filter element aging, replace the filter element;

 

7、Import and export of the filter are reversed, identify the direction of the mark and reconnect;

 

8, the air contains chemicals that the cartridge cannot absorb;

 

9, there are residual pollutants at the point of use, remove the residual pollutants;

 

10, the bypass valve is not closed, close the bypass valve.

 

Compressed air filter repair and maintenance:

 

 

1, the core part of the pipeline filter is the filter core, the filter core consists of filter frame and stainless steel wire mesh, stainless steel wire mesh is a wearable part, need special protection;

 

2, when working for a period of time, the filter cartridge precipitated a certain amount of impurities, when the pressure drop increases, the flow rate will drop, the need to promptly remove the impurities in the cartridge;

 

3, when cleaning impurities, pay special attention to the stainless steel wire mesh on the filter cartridge can not be deformed or damaged, otherwise, after re-installation, the purity of the filtered medium will not reach the design requirements, and the compressor, dryer, instrumentation and other devices will be damaged;

 

4, if the stainless steel wire mesh is found to be deformed or damaged, it needs to be replaced immediately. What are the compressed air filter models? 

Compressed air filter working principle

 

1, Compressed air containing contaminants such as dust, oil, rust and water enters the first stage filter of the compressed air filter. 2, When the compressed air passes through the first stage of the cartridge filter core to create a flocculation effect, the larger particles are adsorbed on the filter material and the water condenses into larger droplets.

 

3, The velocity of compressed air in the separation chamber was reduced, so the particles were collected again, and the water mist was condensed again in the honeycomb water collector.

 

4, Water laden with dirt particles flows along the bottom into a drain device that is drained by an automatic or electric drain valve.

 

5. More than 95% of water droplets, oil and large particles in the compressed air are filtered by the 1st stage filter element, and the compressed air enters the 2nd stage filter element after the 1st stage filtration. 6, when the compressed air passes through the second stage special cotton fiber filter, thousands of small vortices are generated, the compressed air is accelerated by 10 times, the center of the vortex is like a tornado, and becomes a vacuum , the filtered water droplets are gasified, converted, filtered again, and the 5 micron particles are completely removed in a second stage filter.

 

7, two-stage filtration to achieve clean and dry compressed air without dust, rust, oil and water droplets, protect the normal implementation of pneumatic equipment and extend the life of pneumatic equipment. Compressed air filters are basically like many purposes
