Heating shaft alignment in a larger convex curvature at the local heating IS centrifugal pump, temperature controlled at below 600 ℃, and then leveling the ends of the pivot axis, and placed in the bottom supporting the pad, keeping the level of the line, and then in maximum bending (convex) at the pressure, the temperature should rise slowly, not too fast. Heating area and pressure size, should be based on specific circumstances. Supporting plate is lower than required to achieve alignment position some, generally 1 ~ 4 mm, a value similar to the type of the shaft material, the heating temperature, pressure, speed and so on size and force. After straightening meet the requirements of IS shaft centrifugal direct, on-axis heating parts asbestos insulation application number h and then cooled. Should be annealed after straightening, slowly rotating the shaft. Heated to about 350 ℃, incubated 1 h or more steel IS centrifugal pump, and then wrap the heat-asbestos material, the axis of rotation and then cooled to about 70 ℃ natural cooling in air. (1) The water segment mounted on the base, and the base unit bolted firmly. (2) on the inlet side of the pump shaft sleeve assembly, temporarily put on the hub seal ring, packing gland, retaining ring and left bearing cap, and install left bearings, cast in the bearing grease. (3) the shaft from left to right into the water segment string. (4) will be left bearing body and Rolling assembled, and left bearing body and the water segment bolted IS centrifugal | IS Centrifugal Direct | Xin-pump (certified merchants) provided by Hebei Xin-pump factory.
