Autoclave Pressure Tester is a High Pressure system. Autoclave pressure Tester system has following Sub system 1.Air Drive System: Air Drive System has One Manual Drive air Open /Close Valve (1.0), one filter-Regulator (2.0), filter-Regulator is a combination of Filter & Regulator. Filter- regulator is used for filtration and regulation of Incoming drive air. 2.Hydraulic system (Working Fluid ISOPAR): It consists of 50 liters S.S. Tank (8.0), Level Indicator (10.0) which will indicate working media level in tank. 3.Autoclave Chamber: High Pressure Autoclave Testing chamber (26.0) (Design at 200 bar) is used for storage of Unit under test for pressurization up to 150 bar. 4.Electrical & Electronic System: We will use Three Phase Motor (17.0) to run the Filling Pump (16.0) at 1500 rpm. We are Using PLC to Control Different Operation like Start of Filling Pump, Controlling of Pressure Intensifier (26.0) and high pressure pump Operation by Using Pressure Transmitter (25.0 & 5.0) Data & by Providing Control Signal to Electronic pressure regulator (4.0 & 35.0).
