离子氮化需要有一个能稳定地供氨并能精确地调节氨气流量的装置,以保证工艺的稳定执行。但日前大多数供氨装置多为各种减压器(如氧气减压器、液化石油罐用减压器以及其他各种减压器),它们用于离子氮化炉有以下缺点。1.供气压力稳定性小,特别是氧气减压器用于氨瓶压力调节极不稳定。2.抗腐蚀性能差,上述各种减压器中均有铜件及不耐氨腐蚀的橡胶件, Ion nitriding requires a device that provides a stable supply of ammonia and precisely regulates ammonia flow to ensure stable process execution. However, most of the ammonia supply devices are a variety of pressure reducers (oxygen pressure reducers, LPG pressure reducers, and other pressure reducers), which have the following shortcomings for ion nitriding furnaces. 1. Gas pressure stability is small, especially the oxygen regulator for ammonia bottle pressure regulator is very unstable. 2. Anti-corrosion performance is poor, the various pressure reducer in both copper and non-ammonia corrosion of rubber parts,
