Research and Development of Key Components of Positive Pressure Beam Tube Monitoring System

Through the theoretical estimation and experimental verification of the positive pressure gas transmission parameters, the reasonable interval of positive pressure gas transmission time is obtained. In selecting the positive pressure pump, priority should be given to the gas transmission time. Through the test and analysis of diaphragm pump and piston pump with different lengths of beam pipe, it is concluded that the diaphragm pump meets the performance requirements of the design positive pressure pump. The development of positive pressure gas pump by making maps, reverse design and other technical means are completed. The performance test of the positive pressure pump shows that the self-developed positive pressure gas pump can solve the problems of gas lack fidelity and long gas transmission time.
