It can be used for fertilizers, pharmaceuticals, oxygen and pressurized long-distance gas transportation, and other devices. The design of the main tasks are: identification ammonia Section cycle pressor structure, the main structure size, and identify key zero, parts of the structure and size selection. First of all, for strength and stability, mainly a cylinder, cover the wall, the water pressure check and impeller stress test, the axis of strength checking. Secondly, the structural design of ponents. The whole design process is based on norms and standards for design, . engineering design results meet the design requirements.
