Hydraulic Accumulator NXQ1-L25 33 H for Bokaro｜YOYIK

Hydraulic Accumulator NXQ1-L25/33 H for Bokaro Power Plant｜YOYIK
Product Introduction

The product is a hydraulic accumulator of model NXQ1-L25/33 H, featuring bladder-type structure, gas-charged energy storage operation, nominal pressure PN33 (≤33.0MPa) and nominal volume 25L, 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 Bokaro 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 33.0MPa and maximum operating temperature of 120℃, matching the 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 PN33 (maximum operating pressure ≤33.0MPa), nominal volume 25L and maximum operating temperature 120℃, it can adapt to the hydraulic working conditions of Bokaro 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, oil 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 gauge interface and pressure relief device, it can realize real-time pressure monitoring and overpressure protection, facilitating regular inspection and maintenance 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.
