Mawu akuti 'flushing' ndi 'kuzimitsa' often seem to be confused or misused when discussing seal support schemes for >mapampu amphamvu. Monga malingaliro a katiriji wosindikizira wamakina ndi katiriji yosindikizidwa yodzaza ndizosiyana pang'ono, ndizikambirana padera komanso motsatana.

Zimango Zisindikizo

The Basic mechanical seal flushing program is very simple. Pamafunika kuti madzi oyera / oyera (nthawi zambiri madzi) alowetsedwe mu danga pakati pa chisindikizo chenichenicho ndi choletsa cha mbali ya impeller. Kuthamanga kwamadzimadzi kumayambitsidwa ndi kuthamanga kwapamwamba kuposa kuthamanga kwa kupopera, motero kuonetsetsa kutuluka kwabwino / kutuluka kwa chisindikizo cha makina ndi malo ogwirira ntchito oyera.
Flushing imatanthauzidwa ngati "madzimadzi omwe amalowetsedwa muzitsulo zosindikizira pambali yamadzimadzi, pafupi ndi nkhope ya chisindikizo, ndipo nthawi zambiri amagwiritsidwa ntchito kuziziritsa ndi kudzoza nkhope ya chisindikizo.

When flushing is required, the >slurry mpope supplier imalimbikitsa makonzedwe a mapaipi osindikizidwa a API Option 32 chifukwa ndi abwino kwa mautumiki okhala ndi zolimba kapena zowononga zomwe zitha kuwononga nkhope zosindikizira ngati zizunguliridwanso m'njira yothamangitsira.
Madzi oyera oyera omwe amaperekedwa kuchokera kunja nthawi zambiri amagwiritsidwa ntchito omwe amaperekedwa kumalo osindikizira kwambiri kumbali yamadzimadzi ya ndondomeko yosindikiza. Pogwiritsa ntchito phokoso lotsekeka la pakhosi, bokosi losungiramo zinthu likhoza kubwezeretsedwanso mpaka kupanikizika kwakukulu, kuonetsetsa kuti madzi otsekemera sakuwomba pa nkhope ya chisindikizo.

Dongosolo lozimitsa, monga momwe dzinalo likusonyezera, lapangidwa kuti lizimitse kapena kuziziritsa chisindikizo. Amagwiritsidwa ntchito ngati nthawi yayitali yowuma ikuyembekezeka. Monga momwe tawonetsera m'munsimu, madzimadzi amalowetsedwa m'dera lomwe lili pakati pa kumbuyo kwa nkhope za chisindikizo ndi njira yotulukira pafupi ndi galimoto ya mpope.
Nthawi zambiri amagwiritsidwa ntchito ngati nthawi yochepa yowuma ikuyembekezeredwa. Madzi amalowetsedwa m'dera lomwe lili pakati pa kumbuyo kwa nkhope yosindikizira ndi malo otsekera omwe ali mbali ya pampu ya slurry.

Kuzimitsa kumatanthauzidwa ngati "kulowetsa madzi osalowerera ndale (nthawi zambiri madzi kapena nthunzi) mumlengalenga wa chisindikizo kuti ateteze kupanga zolimba zomwe zingasokoneze kuyenda kapena kugwiritsidwa ntchito pazinthu zina.
Zisindikizo zina zozimitsira zimakonzedwa kuti zilowe m'malo mwa chotchinga chothina kwambiri ndi chosindikizira chachiwiri ndi chotuluka chapamwamba chomwe chimatha kuponyedwa paipi kuti chigwire madzi ozimitsa ogwiritsidwa ntchito ndikuchotsa pagulu lozungulira. Komabe mfundo ndi yofanana, timayesetsa kuziziritsa chisindikizocho m'malo mochipukuta mwanjira iliyonse.

Chenjezo: Kulakwitsa kofala ndikukakamiza kwambiri bokosi ndikuwononga chisindikizo chokwera mtengo.

Kunyamula chisindikizo cha bokosi

The main objective of all flush water programmes is to prevent contamination of the seals by pumped water.The flush water programme for boxes is therefore very similar to the flush water programme for mechanically sealed boxes. However there are still some obvious mechanical differences.  The most notable difference is the addition of a seal (packing) between the inlet and outlet limits. This minimises the amount of flushing fluid consumed.

Kumawonekedwe ogwirira ntchito, bokosi loyika zinthu ndi losiyana chifukwa limafunikira kutayikira kuti liwonetsetse kuti mafuta azitha komanso kupewa kutentha. Bokosi losindikizira la makina liyenera kukhala lopanda kutayikira.
Lamulo la chala chachikulu pakuyika kuthamanga kwa madzi ndi lofanana mukamagwiritsa ntchito bokosi la paketi, kaya mukutsuka. Kuthamanga kwa pampu yamatope kuphatikiza 10% kapena kuphatikiza 20 psi, chomwe chili chachikulu. Komabe, kuchuluka kwa kuthamanga kumayikidwa mosiyana.

Ndi ndandanda wamba ya flush, kutuluka nthawi zambiri kumasinthidwa ndikupondereza zonyamula mpaka madontho ochepa amadzi akuwoneka akutuluka kuchokera pazisindikizo pagalimoto. Mu ndondomeko yozimitsira mlingo wothamanga umayikidwa mwa kusintha valavu yolowera, pamene valve imagwiritsidwa ntchito kumbali yotulutsa mpweya kuti ikhale ndi mphamvu yoyenera ya tank. Ngati madzi otuluka mu bokosi la chisindikizo ndi otentha kwambiri, kuthamanga kwake kumawonjezeka mpaka madzi otulukawo atazizira, ndikusungabe kukakamiza kolondola kwa bokosi.

I hope this short blog has helped to clear up some of the confusion about the seal flush programme. Please always refer to the pump manual for specific details. If there are still questions, welcome to >Lumikizanani nafe lero.
