随着汽轮机市场不断向好,各种参数的汽轮机不断开发,在其开发和出厂前均要用蒸汽进行试验,蒸汽参数和试验工况均较复杂。一般蒸汽压力要求在6.4MPa到2.5MPa范围,蒸汽量和蒸汽温度随着汽轮机的规格不同而不同。空载试验蒸汽量可在30~0.5t/h之间,过热蒸汽温度在485~300℃范围内,加上每台汽轮机试验时都有急关汽门而关断用汽工况,造成对供汽管路和供汽设备的汽锤冲击。在其他的应用
With the continuous improvement of the steam turbine market, steam turbines with various parameters are under continuous development. Steam has to be tested before its development and delivery. The steam parameters and test conditions are complicated. General steam pressure requirements in 6.4MPa to 2.5MPa range, steam volume and steam temperature with the steam turbine specifications vary. No-load test steam volume can be between 30 ~ 0.5t / h, superheated steam temperature in the range of 485 ~ 300 ℃, with each steam turbine test off the steam valve and turn off the steam conditions, resulting in Hammer impact for steam line and steam supply equipment.
