The disintegration of the pump :
1. Remove the thrust bearing before using a dial indicator measuring balance disc space, and make a record;
2. The multi-stage pump must be the original assembly sequence of the parts according to the original mark, so as not to return to the chaos, installed;
3. Do not make it easier to mark small (such as key) and the impeller and guide vane (middle) together.
4. The disintegration of the intuitive feel if there is an abnormal parts, such as loose, etc..
Parts maintenance: centrifugal pump :
1. The visual surface is normal, the mating surfaces must be free of scratches, rust etc.;
2. Measured with the measuring key parts of the tolerance is qualified;
3. A measuring impeller sealing ring, a shell body sealing ring, a guide vane sealing ring and sleeve, such as the gap is in the status of the poor range, wear too much needs to be replaced.
4. Check whether the bearing is in good condition;
5. All the sealing ring, sealing gasket is the best new; submersible pump.
Back loading:
1. The rotor is installed, the re balancing test;
2. According to the reverse order of the demolition of the pump back to the parts, back to the attention once again to the amount of the seal ring in the gap value, to ensure that no mistake;
3. The total amount of rotor should be measured before loading the balance disc;
4. Put on the balance after the measurement of rotor on quantity.
5. deep well pump , with the total amount of the production plant assembly drawing on the requirements of the total amount of string and half of the control, should be basically in line with the requirements of the drawings. In general, the half string is about half of the total amount.
6. Evenly tighten the main bolts, attention should be carried out on the diagonal;
7. On the shaft a dial indicator, rotating shaft on the balance disc playing table, tolerance according to the requirements of the drawings, generally not more than 0.06;
8, should pay attention to adjust the gap between the balance disc, should take advantage of bearing before the adjustment ring to adjust the balance disc clearance to the drawing requirements .
