Accumulators, as an important component of fire-resistant fuel systems, play a crucial role in ensuring the stable operation of the system. Here, we will focus on exploring an accumulator NXQ-AB-40/31.5-F-Y, delving into its structure and function, as well as how to effectively maintain and upkeep it.

Firstly, let’s understand the basic principle of an accumulator NXQ-AB-40/31.5-F-Y. Accumulators are mainly divided into two types: high-pressure accumulators and low-pressure accumulators. The high-pressure accumulator is responsible for maintaining the stability of the oil pressure by absorbing the high-frequency pulsation component of the pump outlet pressure, keeping the oil pressure in a stable state. The low-pressure accumulator is responsible for playing an auxiliary role in the pressurized return oil pipeline.

The accumulator NXQ-AB-40/31.5-F-Y is a high-pressure accumulator, which is generally installed on the high-pressure oil main pipe next to the fuel tank. The design of this accumulator allows it to withstand a maximum working pressure of 14.5MPa and a minimum working pressure of 11.2MPa. In actual use, in order to ensure the stability of its performance, the nitrogen filling pressure is generally set at 9.0 ± 0.5 MPa.

After understanding the basic principle and performance parameters of an accumulator, our next step is to explore how to carry out effective maintenance and upkeep. Firstly, the accumulator is connected to the oil system through an accumulator block. There are two shut-off valves on the accumulator block, which can isolate the accumulator from the system and facilitate the discharge of high-pressure EH oil from the accumulator to the oil tank. This allows for online testing or maintenance of the accumulator.

For the maintenance of the accumulator NXQ-AB-40/31.5-F-Y, we need to pay attention to the following points:

1. Regular inspection: Regularly inspect the accumulator to observe whether there is any damage to its appearance, whether the connection is firm, and whether there is any oil leakage.

2. Cleaning: Keep the accumulator clean to avoid the accumulation of dust and dirt, which helps improve its work efficiency and extend its service life.

3. Oil replacement: Regularly replace the oil in the accumulator to ensure its stable performance. It is generally recommended to replace it every six months.

4. Pressure adjustment: Regularly adjust the nitrogen charging pressure of the accumulator according to the actual working pressure to ensure its normal operation.

The maintenance and upkeep of the accumulator NXQ-AB-40/31.5-F-Y requires us to take it seriously in our daily work, regularly inspect and maintain it to ensure its stable performance and smooth operation. Meanwhile, for the maintenance and upkeep of any accumulator, we should follow relevant operating procedures and safety regulations to ensure the safety of work.
