Assembly of head part of pump
1. The back pump shell of the feed pump of the filter press is mounted on the semi-circular end surface of the upper end of the bracket.
2. T-thread of impeller is coated with lubricating grease, and the impeller is mounted on the shaft to compact the auxiliary impeller or the first stage impeller.
3. All connecting bolts between front and rear pump hulls should be tightened evenly. The distance between impeller and pump hull and guard plate should be 0.7-1.50 mm.
4. After installation, check whether the bolt is tightened and whether the grease at the lubrication point is in place. During trial operation, the leakage, vibration and temperature rise of the pump should be checked, and the tightness of the disk roots should be adjusted in time until it is moderate.
