Embodiment
The utility model device be produce at the scene and control criterion pressure transmission to tested pressure transducer, then adopt tested pressure transducer to compare calibration.Comprise source of the gas, pressure controller, pressure charging system, high-pressure gas pipeline and corresponding operation valve etc., source of the gas enters pressure controller by high-pressure gas pipeline after pressure charging system, described pressure controller outputting standard pressure.Pressure charging system comprises the three-way electromagnetic valve 5 and supercharge pump 6 that connect successively.Filtrator 2 and decompressor 3 is disposed with at source of the gas equipped at outlet port.Be provided with between decompressor and three-way electromagnetic valve and drive gas monitoring form 4.High-pressure gas pipeline is disposed with pressurizing vessel 7, system pressure detection table 8, flow controlled valve 9 and output pressure detection table 10.Source of the gas is helium tank 1.Mainly comprise: source of the gas, pressure controller, pressure charging system (containing supercharge pump), high-pressure gas pipeline.
Source of the gas: the operation medium that pressure transmits, selects purity to be that the nitrogen of more than 99.999% is as pressure transmitting medium.
Pressure controller: adopt the CPC8000 full-automatic pressure controller of Mensor production as Main Regulator, pressure is accurately controlled, configuration modular pressure.Measurement range: (0 ~ 20) MPa; Precision: 0.01%FS; Control stiffness: 0.001%.
Pressure charging system (containing supercharge pump): helium from helium tank out after must reach specified pressure needed for controller through pressure piping (supercharge pump).
High-pressure gas pipeline: because the technical indicator high-pressure section of device is higher, reach 20MPa, its safe particular importance.Pipe fitting connection request for checking table is very high, and pressure duct adopts stainless steel material, and whole pipeline must carry out leakage check and bulge test (1.5 times), guarantees No leakage.
