In the performance and parameter comparison, the rotating speed of the imported centrifuge drum is slightly higher than that of the domestic centrifuge; in the corresponding drum structure, the imported centrifuge uses a multi-head auger, and the multi-head auger accelerates the entire pushing process. It also reduces the torsion of the spiral inside the unit. The diameter of the domestic centrifuge drum is slightly larger than that of the imported centrifuge, and the corresponding aspect ratio (refers to the ratio of the effective length of the drum to the effective diameter of the drum) is larger than that of the imported centrifuge. The diameter of the drum is large, and the inner surface The settlement area is large, so the domestic centrifuge uses a double-headed screw ejector. From the operating principle, the longer the effective straight length of the centrifuge drum, the longer the residence time of the suspension in the drum, and the lower the solid content of the discharged clear liquid; the longer the length of the drying section of the cone section, the filter cake after dewatering The lower the amount of water. Artificial climate chambers, etc.
Regarding the lubrication of the main bearing of the centrifuge, the domestic centrifuge is greased. The grease lubrication has strict requirements on the operation. It is necessary to add the quantitative grease (5~10mg) every day, but the main bearing will heat up. If it is added, the main bearing will be shortened. Operating life, grease lubrication requires replacement of the main bearing every year. The imported centrifuge uses forced oil circulation. The forced oil circulation is fully lubricated. It can usually be replaced after one and a half to two years. However, the forced oil circulation increases energy consumption on the one hand, and works during operation and maintenance on the other hand. The oil stain on the spot is large, the operator needs to control the oil pressure and oil return, and regularly change the oil quality. In terms of external dimensions, the domestic centrifuges occupy a large advantage, compact structure, convenient maintenance, small footprint; and designed variable frequency start-up, vibration digital display, and visually see the operating parameters on the display. In the comparison of the above parameters, the key component of Zui is the differential, which is in the heart of the whole set of equipment, so the domestic and imported centrifuges are designed with overload protection.
