Bladder NXQA-25 31.5-L-Y

Bladder NXQA-25/31.5-L-Y & Generator Sealing Oil Pump (ACF090N4IRBP) Seal Leakage Guide
Product Introduction
Bladder NXQA-25/31.5-L-Y is a key component for accumulators in generator systems, matching the ACF090N4IRBP sealing oil pump. Its mechanical seal slight leakage has obvious warning signs, which can be used for advance maintenance.

Leakage Warning Signs Check

- Check the sealing cavity drain port first (most intuitive method).

- Normal state: Dry or with a small amount of oil residue.

- Initial leakage sign: 1-2 drops of oil per minute from the drain port, not to be ignored.

- Check temperature: Touch the sealing cavity shell, 5-10°C higher than usual.

- Check vibration: Vibration feeling is stronger than normal.

- Temperature and vibration abnormalities indicate sealing surface wear and increased friction heat.

- Check oil level gauge: Sealing oil level drops faster.

- After excluding other leaks, confirm ACF090N4IRBP seal leakage.

Maintenance & Operation Precautions

- Do not shut down immediately when finding initial leakage signs.

- Record leakage rate and temperature changes in detail.

- Arrange seal replacement during the next minor overhaul.

- Prepare new ACF090N4IRBP and sealing oil before replacement.

- Avoid damaging the journal when disassembling the pump.

- Apply grease to the end face when installing the new seal.

- Immediate action required if leakage suddenly exceeds 5 drops per minute.

- Excessive oil leakage may enter the generator and cause further malfunctions.

- Early maintenance avoids unplanned downtime.
