交替进入压缩空气,活塞上、下运动带动高压部分上、下运动,使涂料吸入并排出一定压力的涂料。气动型喷涂机一般标有压力比,比值一般为3065∶1,即当进入泵气缸内的压缩空气压力为1个大气压,涂料压力就达到3065个大气压(理论值)。6.2蓄压器蓄压器主要是起涂料液压稳定作用。因柱塞往复泵在上下两个死点时速度等于零,所以易产生压力波动。增设了蓄压器,可减少涂料在喷涂时的压力波动,提高喷涂质量。蓄压器结构比较简单,上、下有两个封头,涂料从底部进入,在进口处有一滚珠单向阀。6.3过滤器因为喷嘴的孔很小,稍有不洁就会堵塞。因此,涂料的过滤尤为重要。无气喷涂设备有两个过滤器,一是装在涂料吸入口的盘形过滤器,目的是除去涂料中的杂质污物第二个过滤器装在蓄压器与高压软管之间,其作用是滤清残存在柱塞缸及蓄压器内的漆料。因为这些剩漆残存时间稍长,就会起皮结块,形成堵塞喷嘴的杂物。实践证明,若在喷枪的进漆处再装一个小型的管状过滤器,就可以确保喷嘴不被堵塞。过滤器的钼丝须经常清洗,以确保良好的喷漆效果。6.4高压软管蓄压器和喷枪之间用高压软管联接。对高压软管的要求是1应选择与涂料源相当的工作压力的耐高压软管,否则会不安全62因为涂料中含有甲苯、
