.使用超滤装置时的注意事项
.Noticeofusingsuperfilterdevice
为了最大限度地发挥超滤膜组件的性能,请注意以下事项。
Inordertomakefulluseofsuperfiltermembranesubassembly,pleasepayattentiontothesepointsasfollows:
1.在使用超滤膜组件之前,请不要排除内部的保存液体。
Beforeusingsuperfiltermembranesubassembly,donotdischargetheinnerpreservationliquidaway.
中空丝膜如果变干燥的话,其性能就会下降以致不能正常使用,所以当暂时中断运行时,请往膜组件内注入清水以保持湿度。
Ifhollowsilkmembranebecomesdry,thecharacterwilldegradesothatitcan’tbeusednormally.Sowhentheequipmentintermitsoperation,pleasefillinmembranesubassemblywithcleanwatertokeepwet.
2.防止膜组件发生冻结。
2.Preventmembranesubassemblyfromfreezing.
3.膜组件容器是用塑料制成的,使用时请注意不要掉落导致破损。
3.Membranesubassemblyismadeupfromplastic,pleasenoticenottodropitresultinginbrokenduringusing.
4.HFM-2020的接合部是配水管耐震接头(维克托利科型管接头)。
在与配管等接续时,请按照配水管耐震接头G型施工要领书正确安装。
如果安装方法不正确的话,可能会导致膜组件的破损。
4.TheconnectionofHFM-2020isaseismicjointofdistributionwaterpipe(VictaulicJoint).Whenconnectingittotubing,pleaseinstallcorrectlyaccordingtoGtypeconstructionessentialsofaseismicjointofdistributionwaterpipe.Ifitisinstalledwrong,themembranesubassemblymaybebroken.
5.在接合部,除了润滑剂以外,请不要沾上其他的油分·
污垢。
5.Ontheconnection,donotwipeupanyotheroilordirtexceptlube.
6.请垂直安装膜组件。
如果不垂直的话,进行空气清洗时会降低清洗效率,敬请注意。
6.Pleaseinstallmembranesubassemblyvertically.Ifnot,thecleaneffectwilldegradewhenairscour.Pleasepayattention.
7.在膜组件通水之前,请务必冲洗配管等部件,并确认没有污垢。
7.Beforefillinginmembranesubassemblywithwater,pleasewashtubingandothercomponentsandmakesurethereisnodirt.
8.在进行通水时,膜组件内有时会残留空气。
为了防止由于水锤导致的膜组件和中空丝膜的破损,请缓慢进水,充分排除空气。
8.Whenfillinginwater,therewillberemainingairinthemembranesubassembly.Inordertopreventthedamageonmembranesubassemblyandhollowsilkmembranewhichiscausedbywaterhammer,pleasefillinwaterslowlysothatitcanreleaseairaway.
9.进行过滤运行时,请不要给膜元件过度加压并注意供水温度。
膜元件的最大供给压力为300kPa(≒3kgf/cm2),如果过度加压的话会导致膜组件以及中空丝膜的破损。
最大供水温度为40度,如果超过此温度的话,会导致膜组件以及中空丝膜的破损。
9.Whenfiltering,thepressureofmembranesubassemblyshouldnotbetoohigh.Payattentiontotemperatureofwatersupply.Themaximumsupplypressureofmembranesubassemblyis300kPa(≌3kgf/cm2).Pressuretoohighwillresultindamageonmembranesubassemblyandhollowsilkmembrane.Themaximumtemperatureofwatersupplyis40℃。
Ifexceedingthetemperature,themembranesubassemblyandhollowsilkmembranewillbebroken.
10.根据原水水质性状设定适当的运行条件。
因为过滤水流量,物理清洗条件等运行条件会对膜的使用寿命,药剂的清洗频率有影响。
10.Setsuitableoperationconditionaccordingtocharacteroforiginalwater.Becauseflowrateoffilterwater,physicscleanandotheroperationconditionswillaffecttheservicelifeofmembraneandfrequenceofmedicamentclean.
根据原水性状,对于一支膜组件,标准的过滤水流量为:
Accordingtocharacteroforiginalwater,foramembranesubassembly,thestandardflowrateoffilterwateris:
HFM-2020,50~200l/min(5~14m3/h)
反洗流量以过滤水流量的1.5~2倍为基准。
Flowrateofbackwashwaterisonthestandardofflowratewhichis1.5~2timesasflowrateoffilterwater.
11.空气清洗时,请设定适当的空气流量。
过度的气流导入会引起中空丝膜的破损。
对于一支膜组件,标准的空气流量为
11.Whenairscouring,pleasesetsuitableairflowrate.Excessiveairflowwillresultindamageofhollowsilkmembrane.Foramembranesubassembly,thestandardairflowrateis:
HFM-2020,200Nl/min(压力:
50kPa以下)
HFM-2020,200Nl/min(pressure:
below50kPa)
12.用化学药剂清洗时,请在适合条件下进行。
由于在不同条件下,或药剂使用错误的话,膜元件的性能就会下降,或导致中空丝膜的破损。
12.Whenchemicalmedicamentcleaning,pleaseproceedinsuitablecondition.Becauseconditionsaredifferent,oncethemedicamentiswrongused,thecharacterofmembranesubassemblywilldegradeorhollowsilkmembranewillbebroken.
