High elasticity reset, sensitive response: high elastic modulus, compression rebound rate ≥ 95%, can quickly deform and reset under the action of high-pressure hydraulic oil, accurately transmit pressure signals, ensure millisecond response of moving blade adjustment, no lag, no jitter.

Anti fatigue and impact resistance, long service life: can withstand ≥ 10 ^ 7 cycles of alternating load, excellent anti vibration fatigue performance, no fatigue, no fracture, and no elastic attenuation under long-term high-frequency vibration, with a service life of up to 8000-12000 hours, reducing replacement frequency.

High temperature and corrosion resistance, strong adaptability: able to withstand high temperatures up to 300 ℃, without softening, deformation, or embrittlement in long-term high-temperature environments; Resistant to hydraulic oil, moisture and heat, and coal powder wear, suitable for harsh working conditions of power station air supply fans.

Precision clearance compensation, stable operation: Accurately compensate for the assembly clearance and wear clearance of the valve body and hydraulic cylinder, prevent hydraulic leakage and pressure drift, ensure the positioning accuracy of the moving blade is ≤± 0.5 °, and stabilize the furnace negative pressure and air supply flow.

3、 Application areas and core usage scenarios

1. Core areas of thermal power generation (main applications)

Widely used in the turbine blade control system of coal-fired power generation unit boilers, covering 300MW, 600MW, 1000MW subcritical, supercritical, and ultra supercritical units. Installed inside the hydraulic actuator of the air supply fan, it cooperates with hydraulic cylinders and servo valves to achieve precise adjustment of the angle of the moving blades, control the air volume of primary and secondary air, ensure stable combustion of the boiler, normal negative pressure of the furnace, and standard steam parameters, and avoid blade jamming, adjustment failure, unit load reduction or unplanned shutdown caused by spring failure. It is a necessary standard spare part for daily inspection, regular replacement, and major and minor repairs of the air supply fan system in thermal power plants.

2. Cogeneration and industrial boiler field

Suitable for urban cogeneration units and large industrial waste heat boilers with axial flow fans, used for regulating and controlling the dynamic blades of high-temperature air supply systems, resisting dust, high temperature, and vibration composite working conditions, ensuring the continuous and stable operation of heating units, and meeting the heating needs of industrial production and residents.

3. Metallurgical and chemical self owned power plant field

Large axial flow fans applied to metallurgical blast furnace supporting power stations and chemical self owned power stations, suitable for complex medium environments such as metallurgical flue gas and chemical waste gas. With high corrosion resistance and wear resistance, the fan regulation system is guaranteed to be stable for a long time, helping to promote the continuous operation of metallurgical and chemical production.
