Hydraulic Accumulator NXQ 2,5 31.5-L-Y for Cirebon｜YOYIK

Hydraulic Accumulator NXQ 2,5/31.5-L-Y for Cirebon Power Plant｜YOYIK
Product Introduction

The product is a hydraulic accumulator of model NXQ 2,5/31.5-L-Y, featuring bladder-type structure, gas-charged energy storage operation, nominal pressure PN31.5 (≤31.5MPa) and nominal volume 2.5L, made of A182 F316/CF8M stainless steel shell and nitrile rubber bladder, specifically designed for power generation facilities, thermal power plants and hydraulic control loops in power station EH systems.

It is mainly applied in the pressure stabilization, energy storage and shock absorption scenarios of Cirebon Power Plant and other thermal power plants, suitable for buffering pressure fluctuations and storing hydraulic energy in power plant turbine EH hydraulic systems, feedwater pump hydraulic circuits and instrument loops, capable of withstanding maximum operating pressure of 31.5MPa and maximum operating temperature of 170℃, matching the high-pressure hydraulic working conditions of power plants, and ensuring stable operation of the entire hydraulic control system.

Company Profile

YOYIK is a leading global manufacturer of industrial valves, power plant equipment and spare parts for power plants, with its core base in Deyang. It focuses on the design, R&D and production of high-demand hydraulic accumulators and power plant hydraulic accessories, and its products are widely used in power, chemical and steel industries, with a complete quality management system and global service network.

Product Features & Operation Points

- Designed with nominal pressure PN31.5 (maximum operating pressure ≤31.5MPa), nominal volume 2.5L and maximum operating temperature 170℃, it can adapt to the high-pressure hydraulic working conditions of Cirebon Power Plant and other thermal power plants, ensuring stable pressure stabilization and energy storage performance and no leakage.

- Adopts bladder-type structure and gas-charged operation, with excellent pressure buffering and shock absorption capability, which can effectively absorb pressure pulses and hydraulic shocks in the system, avoiding impact damage to power plant EH system components and instrument loops.

- The shell is made of A182 F316/CF8M stainless steel and the bladder is made of nitrile rubber, which has excellent corrosion resistance, high temperature resistance and pressure resistance, suitable for EH hydraulic oil medium in power plant systems and ensuring long service life under harsh working conditions.

- Equipped with integrated pressure relief valve and pressure gauge interface, it can realize overpressure protection and real-time pressure monitoring, facilitating regular inspection, maintenance and calibration by power plant operators, and reducing the risk of equipment failure.

- Complies with API 676 and GB/T 15968 standards, with strict quality control in the production process, easy installation and disassembly, and low later operation cost, adapting to the standardized operation requirements of power plant equipment and power generation facilities.

Applications

- Turbine EH hydraulic pressure stabilization systems of thermal power plants

- Hydraulic energy storage systems in power plant EH loops

- Instrument loop pressure buffering accessories of power generation facilities

- Feedwater pump hydraulic shock absorption systems of power plants
