HP Accumulator MXQA-25 31.5-L-EH for Banyuasin｜YOYIK

HP Accumulator MXQA-25/31.5-L-EH for Banyuasin Power Plant｜YOYIK
Product Introduction

The product is an HP (High Pressure) accumulator of model MXQA-25/31.5-L-EH, featuring diaphragm-type structure, gas-charged operation, nominal pressure PN31.5 (≤31.5MPa), made of A182 F316/CF8M stainless steel shell and fluorine rubber diaphragm, 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 and energy storage scenarios of Banyuasin Power Plant and other thermal power plants, suitable for buffering pressure fluctuations and storing hydraulic energy in power plant turbine EH hydraulic systems, capable of withstanding maximum operating pressure of 31.5MPa and maximum operating temperature of 170℃, matching the high-pressure hydraulic working conditions of power plant EH systems, 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 HP 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) and maximum operating temperature 170℃, it can adapt to the high-pressure hydraulic working conditions of Banyuasin Power Plant and other thermal power plant EH systems, ensuring stable pressure stabilization performance and no leakage.

- Adopts diaphragm-type structure and gas-charged operation, with excellent pressure buffering capability and fast energy storage response, which can effectively absorb pressure pulses in the hydraulic system, avoiding impact damage to power plant EH system components.

- The shell is made of A182 F316/CF8M stainless steel and the diaphragm is made of fluorine 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.

- Equipped with integrated pressure monitoring interface, it can realize real-time monitoring of internal pressure, facilitating regular inspection and maintenance of 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 low later operation cost, adapting to the standardized operation requirements of power plant equipment and power generation facilities.
