More Information
Summary:The utility model belongs to the technical field of chromatographic column packing pumps, and particularly relates to a high-pressure gas driven chromatographic column packing pump which comprises a double-output-shaft cylinder, a reversing mechanism and a pair of driving mechanisms, the double-output-shaft cylinder is connected with the reversing mechanism, and the driving mechanisms are connected with the reversing mechanism. One end of the double-output-shaft air cylinder is connected with one driving mechanism, the other end of the double-output-shaft air cylinder is connected with the other driving mechanism, the double-output-shaft air cylinder is suitable for driving the driving mechanisms to alternately reciprocate, the reversing mechanism is triggered when the driving mechanisms alternately reciprocate, so that the double-output-shaft air cylinder is reversed, and alternate reciprocating motion between the driving mechanisms is achieved. The liquid inlet and outlet mechanism is driven to alternately
