Thermal oil pump maintenance should pay attention to the details: I. Disintegration: 1. Demolition thrust bearing should be used before measuring the balance disc gap, and make a record; 2. When the heat pump disintegration of the parts must be the original assembly Order to do a good job mark, so as not to chaos loading, wrong; 3. inconvenient to do the mark of the small pieces (such as key) with the same level of 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. Part inspection: 1. Visual inspection of the surface of each part is normal, the mating surface must be free of scratches and scratches, no corrosion, etc .; 2. The use of measuring the key to meet the site tolerances; 3. The amount of impeller seal ring, the housing seal ring , Guide vane seal ring, 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, gaskets are best for new; 3. Re-install: 1. The first rotor installed, re-balancing test; 2. Press the reverse order to remove the pump to re-install the parts, pay attention to re-install the amount of the gap between the seal ring to ensure correct; Assemble the balance disc before measuring the total amount of the rotor; 4. Equipped with a balance disc, measuring the amount of 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. Under normal circumstances, the amount of semi-series is about half the total amount of the string. 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 adjustment ring bearing balance disc space adjusted to the drawing requirements.
