摘要： PROBLEM TO BE SOLVED: To obtain a measuring apparatus by which a pressure can be measured precisely even when the pressure is changed suddenly by a method wherein a second pressure-measuring pipe in which an orifice is installed in the middle of a water-filled water tank into which the outer end of a first pressure- measuring pipe, one end of which is the pressure detection end of a gas, is inserted from a bottom plate is provided and a pressure verification pipe in which a solenoid valve is installed is provided. SOLUTION: A valve 90 is closed, a hand valve 25 is opened, steam in a steam-turbine evacuation chamber 10 flows into a water tank 80, and a pressure- measuring pipe 20 is filled with the steam. A pressure at a pressure detection end 15 is transmitted to a pressure gage 40 via water inside a measuring pipe 70, and a pressure inside the evacuation chamber 10 is measured by the pressure gage 40. When the pressure inside the evacuation chamber 10 rises suddenly, the pressure is transmitted to the tank 80 so as to be transmitted to the pressure gage 40 via the water inside the measuring pipe 70. As a result, although an orifice 30 is installed, the responsivity of the pressure gage 40 becomes good.

摘要： PURPOSE: To minimize the temperature change width around a steam turbine rotor by quickly closing a high pressure steam governor and decreasing a low pressure steam governor in case of emergency shutdown of a generator, holding the low pressure steam governor in its slightly opened state so as to introduce a cooling air, and cooling an area in the vicinity of a steam turbine low pressure last stage. CONSTITUTION: When the load of a generator 1 is abruptly decreased or shut down in an emergency and a signal of load decrease caused by failure of an auxiliary machine, etc., is input, opening of a high pressure steam governor 8 is quickly closed. A low pressure steam governor 10 is also closed simultaneously with the input of the load decrease signal. After that, the opening of the low pressure steam governor 10 is held in its slightly opened position and the cooling steam is introduced into a steam turbine 2 so as to cool an area in the vicinity of the low pressure last stage of the steam turbine 2. The temperature change width around the rotor of the steam turbine 2 can be thus minimized so that generation of the thermal stress can be decreased.

摘要： PURPOSE:To reduce the frequency of replacing seal fin and the cost therefore by implanting a seal fin, for prevention of leak of steam, in the intended part aslant thereto, and thereby providing possibility of correcting the worn tip of seal fin through folding of this part in the vertical direction. CONSTITUTION:A seal fin 1 for prevention of leak of steam is implanted aslant in the implanting part 3 with the aid of a caulking piece 2. This can prolong the overall length of the seal fin 1. When the tip of this seal fin 1 has worn, it is folded in the vertical direction by an amount r corresponding to the wear so as to maintain the optimum dimension. This reduces necessary frequency to replace the seal fin 1 as well as suppresses the material cost for seal fins 1.
