1. Determine whether the rotation direction of air conditioning pump shaft (impeller) is correct;
2. Whether the rotation is flexible and whether there is a card dead phenomenon;
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;
7. Whether the current is in the normal working range;
D, periodical maintenance and maintenance:
A, lubricated with lubricants, cleaned and replaced once a year;
B. Lubricated with grease, the air conditioning pump shall be replaced once at 2000h;
C. Packing seals shall be used when the leakage or leakage drops are found to exceed the standard for pressing or replacing;
D. Mechanical water seals shall be used for replacement according to the inspection conditions;
