L L1 ?0.00 100 H b×b B B1 5.2安装设备时应注意筒体的垂直度. 5.3设备应紧固牢靠,使用一段时期后应再行紧固. 5.4用户按图5连接进、排气管道(设备上有进出气口标贴)，过滤器、高效除油器应尽量靠近干燥器。 5.5为了保证安全，设备应有效接地。 6.6消声器应接到室外，连接管路应水平或低于排气口，否则会造成部分液体倒流，影响再生效果。 六、HDW微热干燥器PLC控制器出厂设定 6.1主要技术指标和正常使用条件 6.1.1干燥器工作时间:1小时30分。 6.1.2干燥器再生时间:1小时27分钟。 6.1.3干燥器加热时间: 50分钟。 6.1.4干燥器加热控温点范围:?145? 6.1.5掉电后数据自动保留时间:>10年。 6.1.6电磁阀输出容量:4路，每路交流220V/3A。 6.1.7整机功耗:<20W 6.1.8工作电源:交流220V?20%，50/60Hz。 6.1.9环境温度:-10,80?，相对湿度?85%。 6.1.10使用场所应无爆炸性危险介质，周围没有腐蚀性气体。 7 11 七、调试 7.1调试前准备 7.1.1在调试前应先仔细检查各运转部件、仪表控制系统、HDW-PLC控制仪、加热器、电源、接地装置等，若损坏或失灵，应修复。 7.1.2 HDW电脑控制仪出厂前设定为2小时工作时间，一般无须更改参数，上电即可正常运行。 7.2几个相关阀门调节 7.2.1安全阀起跳压力调节至进口压力的1.05倍(出厂时已调好)。 7.2.2调整供薄膜切断阀运行进口压力为0.2,0.3Mpa(出厂时已调好)。 7.2.3如蝶阀,则其运行进口压力为0.55Mpa(出厂时已调好)。 7.2.4调节再生气球阀Q(阀全开即为6%额定量，一般调至中间位置即可)。 7.2.5切断阀的控制气压力需调整时，先拔起调压阀的上旋钮，然后左旋(减少)或右旋(增大)调整完毕压下旋钮即可。 7.3吹洗吸附剂 凡新填充的吸附剂最好先输送压缩空气吹洗放空,把吸附剂中的粉尘吹洗干净. 7.4干燥吸附剂 凡新填充的吸附剂吹洗好后应进行干燥,干燥方法一般用压缩空气干燥:关闭出气阀门,全开进气阀门,送进压缩空气,时间按干燥剂干燥程度确定. 八、使用 8.1先打开空压机待干燥器进气压力,0.5MPa时开启HDW控制仪(先合上控制箱内的控制仪电源空开，然后合上加热器电源空开)，设备即开始运行。停机时只需关掉HDW控制仪电源(先关加热器电源，然后关控制仪电源)即可。 8.2若用户要采用无热运行方式时，可断开加热器电源空开(加热部分出故障会自动断开)，将控制仪内的转换开关置于无热位置，断电后重新开机即可。 8.3未打开干燥器压缩空气也能通过干燥器送到用气点(两塔同时干燥吸附)，此时时间不宜过长。 8.4每次断电后重新开机会自动交换工作塔，可避免一塔重复使用。 8.5本装置在无爆炸危险,无足以腐蚀金属和破坏绝缘介质的室内使用。 8.6当加热部分出现故障时转换为无热运行方式工作，待修理。 九、维护保养 9.1经过长期运转,当干燥系统各项运行参数不变,设备工作正常,而干燥空气达不到露点要求(?-40?),即干燥剂已失效,需调换更新。 9.2再生的吸附筒在排放废气时,其压力应<0.05Mpa.如压力超过此值,则应卸下消声器清除灰尘，使气体流动阻力小,必要时更换滤芯或消声器,一般 8 应把排气管与消声器接至室外。 9.3因气动薄膜切断阀的薄膜工作压力为0.2,0.3Mpa,应经常检查过滤减压阀上的压力表指示是否超过,以防止超压损坏薄膜. 9.4检查再生气球阀,确保在开启状态。 表7常见故障检修表 序 故 障 故障 原因 排除 方法 号 1.1吸附剂不足或破2.1加吸附剂或更换 碎、失效 2.2调整至合理气量，检 1.2再生气量不足或A、查阀门及控制仪 B塔切换不正常 2.3调整工艺配置、提高1 露点达不到要1.3进气温度过高 冷却器冷却效果 求 1.4进气含油量高吸附2.4提高滤油效果，更换 剂失效 吸附剂 1.5工作压力低至使 2.5适当提高进气压力 吸附能力低 2.6合理地调整切换周期 1.6切换周期过长 2.7降低消声器出口高 1.7消声器出口高于图度，防止雨水进入消音器 5的H1或雨水倒灌 2.1吸附剂破损严重 3.1清除破损吸附剂并补2 压力降偏大 2.2过滤器堵塞 充 (? 0.02MPa) 2.3吸附剂超期或已过3.2检查并清理堵塞的过 早破碎成粉尘状 滤器 3.3过筛或更换吸附剂 3.1出气管径不合要求 3.1更换 3 3.2出气管道不畅 3.2清理及排污 流量损失大 4 3.3再生气量偏大 3.3适当减少再生气量 3.4管道弯头过多 3.4适当减少管道弯头 4.1消声器或消声器管4.1清理消声器(更换滤 道堵塞 芯)或清理消声管道5 4.2蝶阀失灵或严重泄4.2检查并更换损坏件4 再生压力不漏 (密封件等) 复零5 4.3再生气量偏大 4.3适当减少再生气量 4.4再生气出气管路不4.4检查出气管路、消声 畅 器等 4.5止回阀漏气 4.5检查阀头 9 11 5.1智能控制仪程序不5.1检查并排除 对 5.2按要求重新调整电磁 5.2电脑控制仪输出端阀接线端，修复或更换控 接线有误或控制仪故障 制仪 5 A、B塔切换不5.3电磁阀损坏 5.3更换 正常 5.4薄膜切断阀(气动5.4检查并更换破损件 6 碟阀)失灵或严重泄漏 (如膜片破裂) 5.5先导电磁阀外接线5.5检查并排除 路故障 5.6检查阀头是否正常 5.6止回阀漏气或卡死 10 11
