Maintenance of air conditioning pump

Maintenance of air conditioning pump

Pre-launch inspection and maintenance:

1. The lubricating oil of air conditioner pump bearing is sufficient and good;

2. Whether the anchor bolt and coupling bolt of air conditioning pump and motor are loose and loose;

3. Whether the air conditioning pump and the intake pipe are fully filled with water;

4. Whether the shaft seal is leaking or dripping (the number of dripping per minute meets the requirements);

5. The horizontal air conditioning pump is required to use the hand-disc dynamic coupling to see whether the pump impeller can rotate, if it can't move, it must find out the reason, eliminate the hidden trouble and restart it.

B. Start-up inspection and maintenance:

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;

E, disassembly overhaul: once a year, the water pump is overhauled and overhauled, mainly including cleaning and inspection;

F, rust brush paint: once a year, the air conditioner pump body without heat insulation is treated with rust.
