摘要
The present invention relates to a test device for output performance of the air drive lifting device for testing during operation of the safety valve to easily test the output performance of the air drive lifting device of the power plant, and the present invention is electrically connected to various operation equipment A control unit (99) for controlling a test function of the air drive lifting device with a built-in data program for testing various functions of the air drive lifting device; A rectangular base plate 100; A lower stud (102) (104) formed at a predetermined length perpendicular to both sides of the upper surface of the base plate (100); An upper plate (106) installed between the lower stud (102) and the lower stud (104) to fix the lower stud (102) and the lower stud (104); Upper studs 20 of the air motor 20-1 to prevent the air motor 20-1 of the air driving lifting device installed on the upper plate 106 from being separated from the upper plate 106. A lower plate 108 for solidifying; An air injector 110 receiving air from the air supply unit 30 by the operation of the control unit 99 and injecting air into the air motor 20-1; An electronic air pressure regulator 112 for adjusting the air pressure of the air motor 20-1 by the operation of the control unit 99; A pressure signal transmitter (114) for transmitting the air pressure of the air motor (20-1) to the controller (99) by the operation of the controller (99); A shaft 116 formed at a predetermined length perpendicular to a lower side of a lower plate so as to be aligned with the center of the shaft of the air motor 20-1; Sensor for tensile stress measurement, which is installed under the shaft 116 and measures the tensile stress of the air motor 20-1 when the shaft 116 moves, and transmits the measured tensile stress to the controller 99. 118; It is installed on the lower side of the tensile stress measurement sensor 118, and consists of a link rod end 118 to align the axis when the shaft 116 moves.;Safety Valve, Air Driven Lifting Device, Test Device, Electronic Air Pressure Regulator, Pressure Signal Transmitter
