(1) Perform a complete scrub and inspection of all parts before assembling the pipe booster pump. Inspect parts for signs of scars, wear, and cracks. If any problems are found, the Hardware Tools should be dealt with (repaired or replaced) before assembly.
(2) Measure the outer diameter of the impeller and the inner diameter of the seal ring with a vernier caliper. Record the results on the record and calculate whether the clearance is between 0.4 mm and 0.5 mm.
(3) shear mat: shear bearing gland, pump cover used mat.
(4) Assemble the rotor: ① Insert the key on the pump shaft and attach the impeller (Note: the direction in which the impeller blades bend is opposite to the rotation direction of the pump and should not be installed in reverse direction). ② Install the front and rear hubs on both sides of the impeller, and fasten the front and rear hubs and impellers to the shaft with front and rear hub lock nuts. ③ The packing sleeve, water seal ring, packing gland, retaining ring and a good green shell paper pad bearing the front bearing cover set on the front sleeve, the seal ring mounted on the impeller mouth. ④ The front bearing mounted on the shaft, and use the casing lock nut (note positive and negative) to the bearing on the shaft. ⑤ bearing and bearing body were added to account for two-thirds of its volume after lubrication, the front bearing body mounted on the bearing, and with a bolt bearing gland and bearing body together.
(5) Assembly: ① The installed pipeline booster pump rotor on the pump body, and the seal ring on the cylinder pin to the pipeline booster pump tank body. If the impeller is not in the middle of the pump body groove, use a tight front and rear bearing lock nut to adjust. ② before and after the bearing body gland were bolted to the bearing body, while the tight side of the disc pump. ③ heating or copper rods percussion method, the key installed coupling mounted on the shaft. ④ add packing: a diameter of the sleeve after measuring the length of the filler, the average chamfering, incision of 30︒ or 45︒; b water seal ring placed in the middle of the filler, respectively, before and after the installation of 2-3 With the filler, not with the incision between the staggered 90 ︒ ~ 120 ︒, the last cut open down. ⑤ a little grease in the contact surface between the pump body and the pump cover, plus a good green shell paper pad, mat coated with a little grease. Cover the pipeline booster pump cover, put on the bolt, and the bolt will be good on the tight side of the disc drive coupling, found that the rotation is not flexible and timely adjustment. ⑥ put on the gland, tighten the gland packing seal bolts, forced to be uniform, gland end face perpendicular to the sleeve, to prevent partial wear. Tight, then release 1-2 buckle. ⑦ hand wheel coupling check pump rotation is flexible, should be non-blocking card, emphasis on the phenomenon.
