C. Operation inspection and maintenance:

1. The motor should not have excessive temperature rise, without the smell;

2, bearing temperature shall not exceed the ambient temperature 35 and 40 , the limit of bearing the highest temperature should not exceed 80

3. Shaft seal (except for the form of water dripping) and no leakage in the receiver;

4. No abnormal noise and vibration;

5. No looseness of anchor bolts and other bolts.

6. There is no obvious distortion of incoming and exit water pipe;
