What to do if the compressed air filter has poor filtering effect

Compressed air has many flexible uses as a power source, such as driving motors, painting, controlling machines and drives, etc. As with plastics processing, compressed air is indispensable for countless processes in the chemical industry. Good quality compressed air can certainly improve the process, but the compressed air containing impurities that are not up to standard will reduce the production process and affect the quality of the product. dpc compressed air filter can remove 99.99% of the liquid water, oil, dust, micro-particles and other impurities in the compressed air.

In practice, sometimes encounter through to the compressed air filter out of the air still contains a lot of impurities, compressed air filter effect becomes worse, what is the reason? 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、The compressed air carrying harmful substances such as dust, oil, rust and water enters the first stage filter of compressed air filter. 2、When the compressed air passes through the first stage of the cartridge mesh filter core to produce the agglomeration effect, larger particles will be adsorbed on the filter material, and water will condense into larger droplets.

3, into the separation chamber, the compressed air speed slowed down, so that the particles once again gathered, water mist again condensed in a honeycomb-shaped water collector.

4、Water laden with impurity particles flows along the bottom to the drainage device, which is discharged through the automatic or electric drainage valve.

5、More than 95% of the water droplets, oil and large particles in the compressed air have been filtered out by the first filter element, and the compressed air after the first stage filtration enters the second stage filter element.

6、When the compressed air passes through the fiber filter made of special cotton in the second stage, thousands of small vortexes will be generated, while the compressed air will be accelerated tens of times, and the center of the vortex will be like a tornado, forming a vacuum, and the water droplets not filtered in the first stage will be gasified, converted and filtered out again, while the particles as small as 5 microns will be completely removed by the second stage filter.

7, by the two-stage filtration to achieve a clean, dry compressed air without dust, rust, oil and water droplets, to protect the normal implementation of pneumatic devices and extend the service life of pneumatic devices. Compressed air filter is generally how much purpose.
