(3) In the hot oil heated roller bearings to 85 ~ 100 ℃, remove the shaft installed at both ends of the shaft. (In order, install deep groove ball bearing, bearing spacer ring and angular contact bearing in the coupling end; install deep groove ball bearing, bearing spacer and angular contact bearing in turn on the impeller end) (4) Shaft pressure mounted in the suspension. (5) Put the paper pad on the two bearing caps, and fasten the bolts on the axle suspension. Note the use of paper pad to adjust the bearing and bearing cover clearance, that is, the amount of shaft movement in the suspension (0.2 ~ 0.3) mm. (6) Install the anti-rotation pin on the static ring seat, and then install the "O" ring and the static seal of the mechanical seal into the static ring seat, press the oil seal into the machine sealing cover, then put on the sleeve and The mechanical seal moving ring mounted on the shaft installed in the machine sealing mouth mounted "O-ring", then the ring sleeve into the machine gland, and then into the machine sealed chamber, with a bolt tight Solid, mounted on the ring seat, and bolted. (7) Put the retaining ring and "O" ring on the shaft, and then fix the sealing chamber to the suspension. (8) Put the "O" ring on the back plate of the rear plate, then install the rear plate on the machine room. (9) Insert the key on the shaft, followed by the impeller, impeller block mounted on the shaft, and then use the round nut, sleeve nut (impeller nut) impeller tightened. (10) will be installed impeller suspension body, bearing room, the rear guard mounted on the pump body with a nut fastened. (11) "O" type snare in the front guard, and then mounted on the pump body. (12) Place the cutter head on the suction pipe and fasten it with the nut on the pump body. (13) Bolt the pump bracket to the suspension with bolts and spring washers. (14) set the key, install the pump coupling. 2, disassemble: according to the assembly in reverse order.
