Hydraulic Accumulator NXQ-A-6.3 31.5-L-Y

Hydraulic Accumulator NXQ-A-6.3/31.5-L-Y & DBDS15GL10/10 Direct-Acting Relief Valve Maintenance Guide
Product Introduction
Hydraulic Accumulator NXQ-A-6.3/31.5-L-Y is a core pressure-stabilizing component for power plant hydraulic systems, matching the DBDS15GL10/10 direct-acting relief valve. The valve’s stable pressure maintenance relies on accurate setting, anti-interference measures and frequent inspections.

Accurate Pressure Setting & Locking
Use a dedicated pressure adjusting wrench; do not use an adjustable wrench.
Insert the wrench into the adjusting knob: clockwise to increase pressure, counter-clockwise to decrease.
Monitor the system pressure gauge in real time during adjustment.
Lock the knob with the lock nut after reaching the set value.
Prevent pressure drift caused by system vibration.

Installation & Anti-Interference Measures
Valve core has pressure compensation function; no manual intervention needed.
Automatically adjusts opening with oil flow changes to maintain stable pressure.
Follow the arrow mark on the valve for oil flow direction; avoid reverse installation.
Reverse installation leads to failure in pressure building.
Clean the oil inlet filter screen regularly to prevent valve core clogging.
Impurity clogging causes unstable system pressure.

Routine Inspection & Calibration
Check the pressure gauge during daily inspections.
If pressure fluctuation exceeds ±0.5 MPa, first check oil cleanliness.
Disassemble the valve core, polish wear marks with fine sandpaper, reassemble and recalibrate.
Perform monthly pressure test: suddenly increase system flow rate and observe fluctuations.
No significant fluctuations indicate stable pressure performance.
