BRY carbon steel centrifugal hot oil pump maintenance matters needing attention

BRY carbon steel centrifugal hot oil pump maintenance should pay attention to the matters needing attention, hot oil pump Structural features: Self-heat cooling structure, small size, saving running costs, good performance, reliable use. 1.BRY carbon steel centrifugal heat pump disintegration: 1. Demolition thrust bearing should be used before measuring the balance disc gap, and make a record; 2.BRY all-carbon centrifugal oil pump disintegration must be the parts According to the original order to make a good mark, so as not to chaos when loading, wrong; 3. Not easy to mark the small pieces (such as keys) can be the same level with the impeller or guide vane (middle) and so on together. 4. Disintegration can be intuitive to see if there are abnormal parts, such as with loose and so on. BRY carbon steel centrifugal hot oil pump parts overhaul: 1. Visual inspection of the surface of the parts are normal, BWCB asphalt pump with the matching surface must not be scratched, no rust, etc .; 2. With the measured amount of the key with the tolerance of qualified parts; 3. The amount of impeller seal ring, the shell seal ring, the guide vane seal ring, the interstage sleeve and other clearances are within the tolerance range, excessive wear and tear need to be replaced; 4. Check the bearings are intact; 5. All seals Circle, the seal is best for new; 3.BRY carbon steel centrifugal hot oil pump back to install: 1 first rotor installed, re-balancing test; 2 according to the reverse order to remove the pump back to the various parts, Re-install the amount of attention to the amount of the gap between the seal ring again to ensure correct; 3. Equipped with a balance plate should be measured before the total amount of the rotor; 4. Equipped with a balance plate, measuring the rotor half of the string. 5. And the total assembly on the assembly map of the total amount required and semi-serial quantity control, should be basically in line with the drawings requirements. LQB bitumen heat pump under normal circumstances, the amount of semi-series is about half of the total series. 6. Tightly fasten the main bolts evenly, pay attention to the angle; 7. Take a dial indicator on the shaft, the rotary shaft hits the balance plate, the allowance should not exceed 0.06 in general; Push the bearings should pay attention to adjust the balance of the disc gap should be used before the bearing ring adjustment balance disc clearance adjusted to the drawing requirements (BRY carbon steel centrifugal hot pump overhaul considerations)
