Uhlolojikelele
Amaphampu e-Peristaltic awuhlobo lwepompo elisetshenziselwa ukuhambisa uketshezi emisebenzini eminingi yezimboni nezokwelapha. Lesi sihloko sizonikeza umbono wamaphampu we-peristaltic futhi sichaze ukuthi ungakhetha kanjani ishubhu elilungile ukuze usebenze kahle.
Inhliziyo yanoma iyiphi iphampu ye-peristaltic ukukhethwa kweshubhu elilungile. Ukukhetha amashubhu kungenza noma kuphule idizayini eyimpumelelo, ngakho-ke kubalulekile ukuqonda ukuthi izinto ezisetshenziswayo zamashubhu, ukuhambisana kwamakhemikhali, nezilinganiso zokucindezela zingathinta kanjani ukusebenza kwesistimu yakho. Izinhlobo ezahlukene zamashubhu zinikeza amazinga ahlukene wamandla nokuvumelana nezimo kuye ngezidingo zohlelo lokusebenza kanye nokucatshangelwa kwezindleko. Ukuqinisekisa ukusebenza kahle, kubalulekile ukwazi ukuthi yiziphi izici okufanele zicatshangelwe lapho ukhetha amashubhu ohlelo lwakho.
Ukucatshangelwa kokukhetha amashubhu
Lapho ukhetha amashubhu ozosetshenziswa ngepompo ye-peristaltic, kubalulekile ukucabangela isicelo, ukuhambisana kwamakhemikhali kanye nezici zokugeleza. I-tubing ekhethwe kahle izosiza ekuqinisekiseni ukusebenza kahle nokusebenza kahle okuvela kupompo.
Izakhiwo zoketshezi olumpontshwayo kufanele zicatshangelwe lapho kukhethwa amashubhu epompo ye-peristaltic. Kuyadingeka ukucabangela izici ezifana ne-viscosity, izinga lokushisa, ingcindezi kanye nokugxila koketshezi ukuze kunqunywe uhlobo olufanele lwempahla ye-tubing. Ukuhambisana kwamakhemikhali kufanele futhi kucatshangelwe njengoba ezinye izinto zingehlisa izinga noma zibe nzima ngenxa yamakhemikhali akhona oketshezini olumpontshwayo.
Izici zokugeleza zingesinye isici esibalulekile lapho ukhetha amashubhu wepompo ye-peristaltic. Lokhu kufaka phakathi izici ezinjengokuqina kodonga, ububanzi bangaphakathi (ID) kanye nobubanzi bangaphandle (OD).
Kungani Kufanele Usebenzise I-Silicone Tubing ye-Peristaltic Pump?
Amashubhu e-Silicone kuyisinqumo esidumile samaphampu e-peristaltic ngenxa yezici zawo eziphakeme. Inokumelana nokushisa okuhle kakhulu futhi ingasetshenziswa ezinhlelweni ezidinga amazinga okushisa aphezulu kunezinye izinhlobo zamashubhu. Ukwengeza, i-silicone iyaguquguquka futhi imelana ne-ozone, ukukhanya kwe-UV, isimo sezulu, namakhemikhali amaningi. Lokhu kuyenza ibe inketho ekahle ezinhlelweni zokusebenza zangaphandle noma lezo ezidinga ukuchayeka kaningi ezindaweni ezinokhahlo.
Amashubhu e-Silicone aphinde anikeze ukuqina okuphakeme uma kuqhathaniswa nezinye izinto ezifana nerabha ne-vinyl. Ayiqini noma iqhekeke ngokuhamba kwesikhathi njengerabha futhi ingamelana nokucindezelwa okuqhubekayo ngaphandle kokulahlekelwa ukunwebeka kwayo. Enye inzuzo yeshubhu ye-silicone yizindawo zayo zokungqubuzana okuphansi ezisiza ukunciphisa ukuguga ezingxenyeni zepompo ngenkathi ihlinzeka ngokusebenza okushelelayo. Okokugcina, ishubhu ye-silicone iyibanga lokudla eligunyaziwe okwenza kuphephe ukusetshenziswa kwezokwelapha, ezemithi, ukucubungula ukudla, ukukhishwa kweziphuzo kanye nezicelo zaselabhorethri.
Ukucatshangelwa kwe-PVC & Polyurethane Tubing
Uma kuziwa ekukhetheni ishubhu elifanele lephampu yakho ye-peristaltic, i-PVC ne-Polyurethane yizinto ezimbili ezisetshenziswa kakhulu. Kokubili kunezinzuzo kanye nezithiyo okufanele zicatshangelwe ngaphambi kokuthenga. I-PVC ibiza ngempumelelo, ingasindi, kulula ukuyikhipha, futhi inokumelana namakhemikhali okuhle kakhulu; kuyilapho i-polyurethane ibiza kakhulu kodwa inikeza ukuguquguquka okuphakeme nokuqina.
Ngaphambi kokwenza isinqumo sokuthi iyiphi impahla oyidingayo ngesicelo sakho, cabangela izici ezifana nebanga lokushisa (PVC kufika ku-140°F/60°C), isilinganiso sokucindezela (i-polyurethane kufika ku-145 PSI), ukuhambisana kwamakhemikhali (PVC nama-alkalis, izisekelo & notshwala; i-polyurethane enama-asidi namafutha), ukuzwela kwe-UV (i-PVC idinga ama-UV inhibitors uma eveziwe) kanye nokusebenza kahle kwezindleko.
Ukukhetha usayizi nobude obulungile
Uma kuziwa ekukhetheni usayizi olungile nobude beshubhu yepompo yakho ye-peristaltic, kunezinto ezimbalwa okufanele uzicabangele. Okokuqala, udinga ukuqaphela ububanzi bangaphakathi (ID) kanye nokujiya kodonga lohlelo lwakho lokusebenza njengoba lokhu kuzonquma usayizi ofanele wephampu yakho. I-ID kufanele ibe nkulu ngokwanele ukuze ikwazi ukumumatha wonke uketshezi oluzomponthwa kodwa lube luncane ngokwanele ukuze ipayipi lingahlanekezeli noma linyakaze lapho ligoba phakathi kwamarola ngaphakathi kwekhanda lepompo. Ubude beshubhu kufanele futhi bucatshangelwe njengoba ishubhu elide kakhulu lingase libangele ukungqubuzana okwenyukayo okungaholela emazingeni okugeleza kancane. Kubalulekile ukukhetha ukwaziswa okufanele kukho kokubili uhlobo lweshubhu nesixhumi ukuze kuqinisekiswe ukuhambisana nanoma imaphi amakhemikhali angase ahlangane nawo ngesikhathi sokusebenza.
Ukuhlaziya Izimpawu Zezinga Lokugeleza
Ukuhlaziya izici zesilinganiso sokugeleza kuyisinyathelo esibalulekile ekukhetheni ishubhu elilungile lephampu yakho ye-peristaltic. Izici zesilinganiso sokugeleza zifaka isivinini, ukugeleza kwevolumu, ingcindezi, kanye ne-viscosity ye-medium empontshwayo. Ukwazi ukuthi yiziphi izici zezinto ozozimpompa kufanele kukusize ukhethe ishubhu elifaneleka kakhulu uhlelo lwakho lokusebenza oluthile.
Uma ucubungula izinga lokugeleza, kubalulekile ukuqonda amandla okuthi uketshezi luhamba kanjani ngepompo ye-peristaltic. Izinto ezifana nokucindezela okusetshenzisiwe kanye nokokusebenza kweshubhu kungathonya ukuthi uketshezi luhamba ngokushesha noma kancane kanjani ohlelweni. Kanjalo, imiphumela enembile idinga ukucatshangelwa ngokucophelela kwezinto ezifana nobubanzi bangaphakathi, ububanzi bangaphandle, ukujiya kodonga, nobude beshubhu lapho kukhethwa usayizi weshubhu ukuze usebenze kahle. Ukwengeza, ezinye izingxenye ezifana nama-valve zingase zidinge ukucatshangelwa lapho kunqunywa amazinga okugeleza afanelekile.
Isiphetho
Isiphetho sesihloko esithi, "Indlela Yokukhetha I-Tubing Yephampu Yakho Ye-Peristaltic," ukuthi kunezici ezihlukahlukene okufanele uzicabangele lapho ukhetha amashubhu epompo yakho ye-peristaltic. Okucatshangelwayo okuyinhloko kufanele kube uhlobo lwempahla kanye nokuhambisana kwayo noketshezi olumpontshwayo. Isibonelo, irabha ifaneleka kangcono uketshezi olusekelwe emanzini, kuyilapho i-PTFE noma i-FEP ingcono kumakhemikhali anolaka. Ezinye izici ezibalulekile zihlanganisa usayizi weshubhu, ukujiya kodonga nobude, izidingo zokusebenza ezifana nokucindezela kanye nezilinganiso ze-vacuum kanye nezindleko. Ekugcineni, kufanele kucatshangelwe ngokucophelela isici ngasinye ukuze uthole inketho yeshubhu efanele yohlelo lwakho lokusebenza.
Ngaphezu kwalokho, kubalulekile ukukhetha umkhiqizo wekhwalithi ephezulu kumhlinzeki onokwethenjelwa ongahlinzeka ngosizo lobuchwepheshe uma kunesidingo. Qiniseka ukuthi ufunda izibuyekezo eziku-inthanethi futhi wenza ucwaningo kunoma iyiphi inkampani ngaphambi kokwenza isinqumo sokuthenga.
