Abstract:
Objective To execute experimental study injection rate and volumetric error and to explore their correlations with sizes of injectors and extension tube,so as to lay a foundation for the quality control of the injection pump.Methods Simulation experiment was carried out with involving in 10,20 and 50 ml of injectors and 80 and 120 cm extension tubes,and 6 kinds of connection systems were formed with auxiliary appliances.The injection rate and flow reading of the flow meter were obtained and then compared with the set values,and the correlations were proved between sizes of auxiliary appliances and the precision of injection dose and rate.Results In case other conditions kept the same,the injector with larger capacity behaved better in controlling injection rate and dose,and the shorter extension tube gained advantages over the longer one in regulating the precision for injection and injection dose.Conclusion The experiment contributes to the selection of auxiliary appliances and the enhancement of quality control,and the further research provides references for process design and materials selection of the injector.
