| When using the Coal mill nozzle dynamic ring 22MG23.11.08J.05, first pay attention to correct installation and adjustment. Before installing the nozzle dynamic ring, the static ring of the nozzle should be installed first, and ensure that the removable part of the support is correctly installed to the roller gate of the middle frame, but do not wedge it for the time being. Next, use a gasket to adjust the static ring of the nozzle so that it is in a horizontal state. After installing the nozzle dynamic ring, carefully adjust the gap between the dynamic ring and the static ring, measure the gap with a feeler gauge and record its gap value, and ensure that the gap between the dynamic ring and the static ring is uniform at about 5mm. Too large or too small a gap will affect the normal operation of the coal mill, so be extra careful when adjusting. During the operation of the coal mill, it is necessary to strengthen the monitoring of the nozzle nozzle dynamic ring 22MG23.11.08J.05. The nozzle dynamic ring will be eroded by the primary wind and worn by the coal powder, so the wear of the nozzle dynamic ring should be checked regularly. Excessive wear will affect the ventilation flow rate, resulting in an increase in the discharge of stone coal, which will affect the efficiency and stability of the coal mill. At the same time, the wind speed and wind pressure of the primary wind should be monitored to ensure that they are within a reasonable range. Too high or too low wind speed and wind pressure will have an adverse effect on the nozzle dynamic ring. Too low wind speed may cause the coal powder to fail to be blown out in time, while too high wind speed will aggravate the wear of the equipment. Maintenance and replacement are the key links to ensure the normal operation of the nozzle dynamic ring. When the nozzle dynamic ring is severely worn, it is necessary to replace it with a new one in time to avoid abnormal operation of the coal mill due to excessive wear. When replacing the integral nozzle ring, the separator and pressure device need to be disassembled. This process should be done carefully to avoid damage to other parts. In addition, some anti-wear measures can be taken to extend the service life of the nozzle dynamic ring, such as wear-resistant treatment on the surface of the nozzle dynamic ring, or adding anti-wear lining to the nozzle dynamic ring to reduce wear. |
