The Safety Evaluation Of Aerosol Can And Development Of Pressure Inspection Instrument

First this thesis introduces the manufacturing of pressure inspection instrument for aerosol cans, analyzes the theory of inspection and constitution of equipment.then states the insepection method. Then carries on the narration through the comparison way to this series checker's characteristic. Finally brings forward the especially means of the inspection instrument.The atomization packs in a can the strength tester inspects an atomization pot resistance to pressure important target. The atomization pot packing only then has the good resistance to pressure, can guarantee that does not have internal installation outside in the circuit to release.This tester has used automatic technologies and so on barometric pressure control, intelligent constant pressure, drifting tracing analysis, the union digit sensing, the module transmission data, the computer software processing data, enhances the gas injection pressure the precision, uses the computer pressure gauge electrical signal input, the procedure pressure judgement forecast algorithm and so on advanced method; Uses the computer system and the essence for with thickly for the dual pipelines, the impact reduces to the air current to the pressure gauge is quite small, reduces the error which greatly introduces by the pressure gauge, the intellectualized management the error is only restricted in the electric current outlet error; The control in the 0.003Kpa,0.01 second error range, responded that the determination by becomes the procedure software determination artificially, through the special software algorithm, the filtration unwanted signal, enhanced the instrument performance, reduces the working strength, formerly the manual control, the visual observation, the verification mode sequencing which, the standardization determines depending on the experience, uses the automatic recording, the automatic time, saves the manpower and the time, raises the working efficiency, reduces cycle which the examination shows an ID.This pilot system has used the pressure behavior survey technical principle, carries on the liquid steam tension test, unifies has pressed technologies and so on control, digital pressure sensing, integrated the module transmission data, the computer software processing data, uses to the liquid dangerous material dangerous characteristic analysis.
