Filtration accuracy ≤40μm
Liquid temperature 10~70°C
Secondary oil pressure working range 0.15~0.45MPa
The quick-closing servo control device is composed of a quick-closing security control device and a servo amplifying device. It has the basic functions of the speed-off security device, and in combination with the servo amplifying device, it combines two single-part sets in the system.
The functions are realized through the internal pipeline of the module, and the structure is compact. In operation, the monitoring difficulty and the accident of oil leakage and fire are avoided, and the reliability and safety of the steam turbine are increased.
