product name: high quality gas charging trolley
1. general description.
CDZ - Y1 nitrogen charging car for NXQ series hydraulic bag type accumulator, hydraulic piston accumulator, the hydraulic diaphragm accumulator (including import accumulator) and other special high-pressure container filling, charging nitrogen charging device, the maximum pressure of the nitrogen pressure 42 mpa.
This type of nitrogen charging car by asahi of fenghua hydraulic co., LTD. (formerly fenghua hydraulic parts factory) manufacturing. At home, this company is the only manufacturer through national technical appraisal, the nitrogen charging car to solve the key problems of the high pressure accumulator filling nitrogen, raised the speed of the nitrogen inflator, strengthen the utilization of nitrogen, and filled the domestic blank, at the same time won the zhejiang science and technology achievement award, and achieved national patent (patent number: ZL97229429.5), by the national iron and steel (group) corporation, aerospace, military industry, etc. The user's high praise.
2. working principle.
Usually nitrogen cylinder directly to energy storage gas nitrogen inflator, the highest air (nitrogen) pressure is 13.5 MPa, if accumulator within the required fill nitrogen pressure is greater than 13.5 MPa, with direct aeration method cannot meet the requirements of the accumulator aeration, the enterprise manufacturing CDZ type nitrogen charging car can satisfy the requirement of high pressure nitrogen filling high pressure accumulator, (the highest nitrogen charging pressure for 42 MPa)
This type of nitrogen charging car by hydraulic equipment, pneumatic device and circuit device and so on, when the pressure fluid through the reversing valve into the supercharger, push the piston moving up (down), to enter (under) on nitrogen pressurization of the supercharger, and by the check valve into the accumulator (or high pressure vessel), the piston so up and down reciprocating motion, make nitrogen pressurization to the required working pressure (mpa) within 42.
