Improved application of ecg excavator compressor filter in quarries

F igure 6. Single-layer and double-layer filter comparison graph as a result of research

The size of a new one-layer filter is 260 g, after 10 days of use in an excavator compressor, it was found to be 436 g and 176 g of dust was collected.

The new one of the large filter in the double-layer filter is 920 g and it was used for 10 days in the compressor and it was 1154 g and 234 g of dust was collected, and the new one of the small filter in the second layer was 360 g and when it was used for 10 days it was 408 g and 48 g of dust was collected. it was found that a double-layer filter can catch 60% more dust than a single-layer filter.
Therefore, instead of a single-layer filter device, a double-layer filter device was proposed, and the velocity vector generated by the air flow was fully compared and analyzed between single-layer and double-layer filter devices. As a result of the analysis, the amount of dust passed through a single-layer filter device and a double-layer filter device was studied using a DMX-4 brand microscope based on the samples of the AFA-VP-20 allong filter. was 3.5 μm, and Fig. 7 shows the microscope images.

As a result of experimental studies, it was found that the amount of dust passing through the filter was reduced by 75%, as a result of the installation of guides on the diffuser of the filter shell, the production period was extended by 6 times without damaging the filter, and the compressor service life was increased by 1.15 times.
