When the polyurea spraying equipment is running, some faults will inevitably occur. The following are some of the common faults and their causes:
1. Leakage of the booster pump
Reasons: (1) Insufficient force of the oil cup to press the seals causes material leakage
(2) Long-term use of damaged seals
2.Black material crystals on the shaft
Reasons: (1) The oil cup is not tightly sealed, and the booster pump shaft does not stop at the bottom dead center. There is black material on the pump shaft for a long time without any treatment.
(2) Although the oil cup is tightened, the contaminated lubricant is not replaced
3. Leakage of the feed pump
Reasons: (1) Oil leakage at the lifting shaft. Tighten the oil cup to tighten the sealing ring of the lifting shaft.
(2) Material leakage at other threads
4. Air leakage from the feed pump
Reasons: (1) The "o" ring and "v" seal ring are worn for a long time.
(2) Wear of reversing rubber cap
(3) Air leakage at the thread of the reversing assembly
(4) The commutation assembly falls off
