四、應(yīng)用領(lǐng)域
Woodward GII超速保護(hù)器8237-1596可廣泛應(yīng)用于各種需要超速保護(hù)的場(chǎng)合，如電力、石油、化工、冶金等行業(yè)的旋轉(zhuǎn)設(shè)備保護(hù)。
Woodward GII overspeed protector 8237-1596 is a high-performance overspeed safety device launched by Woodward Corporation.
1、 Product Overview
Woodward GII overspeed protector 8237-1596 belongs to the ProTech GII series and is an upgraded product of ProTech 203. This device is designed to sense overspeed or excessive acceleration events and can safely shut down rotating equipment such as steam turbines, gas turbines, and water turbines to prevent equipment damage or safety accidents caused by overspeed.
2、 Main features
Triple modular redundancy architecture: 8237-1596 adopts a triple modular redundancy architecture and a two out of three voting logic, which improves the reliability and security of the system. Even if one module fails, the other two modules can continue to work, ensuring the stable operation of the system.
MPU detection and sulfur resistant coating: The device is equipped with MPU (microprocessor unit) detection function, which can monitor the operating status of the equipment in real time. Meanwhile, its sulfur resistant coating design enables it to be used for a long time in environments containing corrosive gases such as SO2 and H2S.
Easy to integrate and communicate: The 8237-1596 is equipped with a Modbus communication interface, which facilitates integration and data exchange with other control systems.
Real time recording and logging function: This device has real-time recording and logging function, which can record all tripping, alarm, quick closing valve response time and overspeed events, and can download the recorded data to the computer for analysis.
Compliant with multiple standards and certifications: Woodward GII overspeed protector 8237-1596 complies with API670 and API612 regulations, as well as various safety and electromagnetic compatibility standards in North America and the European Union.
