How servomotor controls throttle valve of TURBINE?
I m appointed as an automation trainee engineer in small firm in that I am only the one , my company give me a project on s7-200 as i m beginner I don't know how to program so please send me the helpful site so that I complete my project before deadline....please help me out in this critical situation.
Calculate the maximum pressure drop that can be allowed to occur across a control valve, so that we can prevent cavitation / flashing from occurring. Use the following formula: Δ P allow = Km (P1 – PvapourA) where, Δ P allow - the maximum allowable differential pressure for sizing purposes, or terminal pressure drop; Km- the valve recovery coefficient from the manufacturer’s catalogue; P1 - absolute inlet fluid pressure; PvapourA - absolute fluid vapour pressure at the inlet temperature; Use Atmospheric pressure = 101.3 kPa, P1 = 1200 kPa(g), PvapourA = 4 kPa, KM = 0.72
