简述zyx—45型隔绝式压缩氧自救器的佩戴步骤
佩戴步骤：
1、将专用腰带穿入自救器皮带环，固定在背部右侧腰间。
2、使用时先将自救器转到腹前，一手托底，另一手拉开锁口带，并弃之。
3、随后扳开带有红色标记的开启扳手，拉开封口带，丢掉上盖。
4、展开气囊，取下口具塞。
5、将口具放在唇齿之间，牙齿咬住牙垫，紧闭嘴唇。
6、逆时针打开气瓶开关旋钮。
7、用拇指按动补气压板。
8、气囊鼓起时迅速把鼻夹掰开，用鼻夹垫夹住鼻翼。
9、调整呼吸，迅速撤离现场。
压缩氧自救器怎么充气
压缩氧自救器使用方法：将自救器从佩戴时的腰部侧面移到人体正前面。用左手水平用力拉着力环，使上壳上的塑料挂钩从下壳脱出；用右手解开上下外壳的金属连接扣鼻，再用手沿竖直方向将上壳提起，使它上下壳脱离。这样就完成了自救器的启封。取下口具，将口具放在唇齿之间，牙齿紧紧咬住口具牙垫，并紧闭嘴唇，使人体口腔与口具之间有可靠的气密。逆时针转动气瓶把手，然后马上沿水平轴向按动手动供气阀，气囊鼓起后松开手指，迅速掰开鼻夹夹住鼻翼两侧，使鼻腔与外界隔绝，用嘴通过口具呼吸。使用过程中应每隔－分钟按动手动供气阀，向气囊及时手动供气。气囊鼓起后，停止手动供气。压缩氧自救器使用注意事项：入井前要注意观察压力表指示值，若示值低于是Mpa，则需对其充氧后方可保证有效使用时间。在使用过程中，最好用右手抚住氧气瓶开关体，以便能及时按动手动补气阀向气囊内供氧气。用手动补氧时，切不可将气囊充得太满，以刚好充满而口内又无压迫感为宜。否则，人会感到呼气困难和造成口具脱落。要随时观察压力表，以掌握耗氧情况及撤离灾区时间。使用过程中，要保持沉着，呼吸要慢而深，以便二氧化碳的充分吸收。在使用分钟左右后，温度会略有上升，不必惊慌。
氧气自救器的工作原理是什么
氧气自救器工作原理：中煤自救器使用时，逆时针转动气瓶阀门，高压氧气从氧气瓶通过减压阀减压，以≥1.2L/min进入气囊，手离开补气压板补养停止。当呼吸系统为负压时，补气压板向内收缩，压迫补气杆打开补气机构，氧气以≥60L/min充入气囊，当气囊鼓起时，补气压板离开补气杆，补气停止。如果呼吸系统内的气压超过排气阀排气压力，气体将从排气阀溢出。吸气时，气囊中的氧气通过口具进入人体。呼气时，气体经过呼气软管进入清净罐，气体中的二氧化碳呗置放在清净罐内的CO2吸收剂吸收，ymjt04余下的气体进入气囊，按成呼吸循环。
