该机长期使用以后,往往引起压缩空气喷射嘴和样品引出嘴锈蚀,使二者的角度和距离发生改变,造成雾化效果恶化,灵敏度下降,稳定性和重复性变坏,甚至无法正常使用。锈蚀以后,可以用一般方法调整二者的相对位置,但由于它们是固定在混合球底部的,调整受到很大限制,效果并不理想。特别是锈蚀严重时,用调整的方法是不能修复的。可用两只不锈钢注射针头代替原压缩空气喷射嘴和样品引出嘴,收到满意 After long-term use of the aircraft, it often causes the compressed air spray nozzle and the sample outlet nozzle to rust, so that the angle and distance of the two are changed, resulting in deterioration of the atomization effect, decrease in sensitivity, deterioration of stability and repeatability, and even failure in normal use. After rusting, the relative positions of the two can be adjusted by general methods, but since they are fixed at the bottom of the mixing ball, the adjustment is greatly limited and the effect is not ideal. Especially when the corrosion is severe, the method of adjustment cannot be repaired. Two stainless steel injection needles can be used instead of the original compressed air jet nozzle and sample outlet nozzle to receive satisfaction
