Improved application of ecg excavator compressor filter in quarries

IMPROVED APPLICATION OF ECG EXCAVATOR COMPRESSOR FILTER IN QUARRIES
The service of the compressor equipment, which supplies compressed air to the brake cylinders, is incomparable in stopping the movements of the working mechanisms of excavators at the right time. For this, the compressor and its equipment must be of high quality, reliable and efficient operation. Therefore, it is necessary to pay attention to the function of the filter device.

Figure 1a shows the shell of the filter device, which is made of metal in a cylindrical shape. A single-layer filter device is placed inside it. Figure 1b shows the diffuser of the shell, which is the air inlet. Figure 1v shows the direct effect of air and airborne dust on the filter unit, showing the filter erosion caused by the incoming air.

Figure 2 shows the amount of dust retained in the diffuser part of the single-layer filter device of the filters of the compressor device of steel wire rope excavators for 10 days. As a result of the experiments, the amount of dust particles trapped in the filter around the diffuser part is presented, and based on this graph, the amount of dust in the filter device for 10 days is presented. It was 0.03 kg.

Figure 3a shows the shell of a two-layer filter device, which has the appearance of a cylinder. As a result of installing the air distribution diffuser on the shell in Fig. 3b, the distribution of the air filter to all points can also be confirmed by Fig. 3b. It can be seen that the effect of the filter on the life of the filter has increased with the correct penetration of the filters in the air inlet.
