The bladder type hydraulic accumulator NXQA-10/31.5 plays an important role in the EH oil system of steam turbines. Its main function is pressure buffering and energy storage to stabilize system pressure, ensure the normal operation of the oil pump, and provide additional hydraulic power. To ensure the safe and reliable operation of the steam turbine, it is necessary to regularly inspect and maintain the bladder type hydraulic accumulator.

When inspecting the accumulator NXQA-10/31.5, the first step is to conduct a visual inspection, including checking for cracks, deformations, or leaks in the accumulator casing, connecting pipes, and joints. In addition, it is necessary to check for any signs of swelling, deformation, or damage to the capsule to ensure that it is in the correct position and not displaced.

Next, connect a suitable pressure gauge to the pressure interface of the accumulator NXQA-10/31.5 and measure its current pressure. Compare the design pressure to ensure that the pressure of the accumulator is within the normal operating range. If there are abnormalities, they should be dealt with promptly.

The quality and cleanliness of the oil have a significant impact on the performance of the NXQA-10/31.5 bladder type hydraulic accumulator. Therefore, during the inspection process, attention should be paid to the color and cleanliness of the oil to ensure that there is no contamination or sediment. Regularly replace the oil to maintain the cleanliness and performance of the system.

Accumulators NXQA-10/31.5 that have not been used for a long time may require venting to prevent gas from occupying unnecessary space. Perform a pressure cycling test on the system to check if the accumulator can be filled and drained properly. Observe the response time of the system pressure to ensure that the accumulator can meet the pressure requirements of the system.

Record the inspection results and compare them with previous records to monitor the performance changes of the accumulator. Based on the inspection results, develop corresponding maintenance plans, including replacing oil, capsules, or seals.

In summary, regular inspection and maintenance of the NXQA-10/31.5 bladder type hydraulic accumulator is crucial for ensuring the reliability and safety of the turbine EH oil system. By strictly implementing inspection procedures and promptly identifying and addressing issues, it helps to extend the service life of the equipment and ensure the safe and stable operation of the steam turbine. In the actual operation process, all safety regulations and operating guidelines should be followed, and professional technicians should be hired for maintenance and repair if necessary.
