摘要
针对工作介质中含有粉尘、焦油等杂质导致的传统压缩机气阀容易堵塞的问题,对传统压缩机环状阀进行了结构改进,设计了抗堵塞环状阀。抗堵塞环状阀在升程限制器与环状阀片接触的环形表面上开设环形凹槽,在未设导向凸台的径向筋表面开设弧形凹槽。通过对抗堵塞环状阀进行吹风试验,验证了弧形凹槽能提升气阀有效通流面积,且随着气阀升程减小,气阀流量系数增加值增大。抗堵塞环状阀在工作介质含较多杂质的煤化工领域6M40-305/314氮氢气压缩机应用时,与传统环状阀相比,一级气阀的清洗次数由原来平均1个月8次下降到平均1个月1.5次,压缩机的排气量提升了6.88%,压缩机一级单位质量工作介质指示功下降了7.85%。抗堵塞环状阀的应用表明,抗堵塞环状阀能延长压缩机连续运转周期、提升压缩机排气量以及降低压缩机功耗。
For the problem of easy clogging of air valves of the conventional compressor due to impurities in the working fluid,such as dust and tar oil,the anti-clogging ring valve was designed through structural improvement of the conventional ring valve.Ring grooves were machined on the ring surface of the anti-clogging ring valve where the lift limiter and ring valve plate contact,and arc grooves were machined on the surface of radial ribs without guiding boss.Through blowing tests conducted on the anti-clogging ring valve,it is verified that the arc grooves can improve the effective flow area of the valve,and the added value of the flow coefficient increases with the decrease of valve lift.When the anti-clogging ring valves were applied to 6M40-305/314 type H_(2)-N_(2) compressors in the coal chemical field with more impurities in the working fluid,compared with the conventional ring valves,the mean cleaning frequency of the first-stage valves dropped from 8 times a month to 1.5 times a month.The displacement was improved by 6.88%.The indicated power of the first stage of the compressor per unit mass of the working fluid was reduced by 7.85%.The application results of the anti-clogging valves show that the valves can extend the operating periods and the displacements of the compressors,and can reduce the power consumption of the compressors.
