Impeller kudula ndi ndondomeko Machining awiri a impeller (tsamba) kuchepetsa kuchuluka kwa mphamvu anawonjezera madzimadzi dongosolo. Kudula chopondera kumatha kupanga zowongolera zothandiza pakupopera ntchito chifukwa chakuchulukirachulukira, kapena machitidwe osamala kwambiri apangidwe kapena kusintha kwa katundu wamakina.

Ndi liti pamene muyenera kuganizira za Impeller Cutting?

Ogwiritsa ntchito akuyenera kuganizira zodula choyikapo nyali ngati izi zikachitika:

1. Ma valve ambiri a bypass amatseguka, zomwe zikuwonetsa kuti zida zamakina zimatha kuyenda mopitilira muyeso

2. Kuthamanga kwambiri kumafunika kuti muwongolere kuyenda kudzera mu dongosolo kapena ndondomeko

3. Phokoso lalikulu kapena kugwedezeka kumasonyeza kuyenda mopitirira muyeso

4. Kugwira ntchito kwa mpope kumachoka kumalo opangira (kugwira ntchito pang'onopang'ono)

Ubwino Wodula Ma Impellers

Phindu lalikulu la kuchepetsa kukula kwa ma impeller ndikuchepetsa ndalama zogwirira ntchito ndi kukonza. Mphamvu yamadzi yocheperako imatayidwa pamizere yodutsa ndi ma throttles, kapena imatayidwa mu dongosolo ngati phokoso ndi kugwedezeka. Kusungirako mphamvu kumakhala kofanana ndi kyubu yochepetsedwa m'mimba mwake.

Chifukwa cha kusakwanira kwa ma motors ndi mapampu, mphamvu yamagalimoto yofunikira kuti apange mphamvu yamadzimadzi iyi (mphamvu) ndi yayikulu.

Kuwonjezera pa kupulumutsa mphamvu, kudula multistage vertical turbine pump impellers amachepetsa kuvala ndi kung'ambika pa mapaipi dongosolo, mavavu ndi zothandizira chitoliro. Kugwedezeka kwa chitoliro chifukwa cha kuyenda mosavuta kutopa ma welds ndi mawotchi olumikizirana. M'kupita kwa nthawi, ma welds osweka ndi zolumikizana zotayirira zimatha kuchitika, zomwe zimapangitsa kutayikira ndi nthawi yocheperako kuti akonze.

Mphamvu zamadzimadzi zochulukirapo ndizosafunikiranso potengera kapangidwe kake. Zothandizira mapaipi nthawi zambiri zimakhala zotalikirana komanso zokulirapo kuti zisasunthike potengera kulemera kwa chitoliro ndi madzimadzi, kukhathamira kwapaipi yamkati mwadongosolo, komanso kukula komwe kumachitika chifukwa cha kusintha kwa kutentha kwa magwiridwe antchito amphamvu. Kugwedezeka kwamphamvu kwamadzi ochulukirapo kumayika katundu wosapiririka pamakina ndipo kumabweretsa kuchucha, kutsika ndi kukonza kwina.

kupereŵera

Kudula vertical multistage turbine pump impeller kumasintha magwiridwe antchito ake, ndipo kusagwirizana m'malamulo ofanana okhudzana ndi makina a impeller kumapangitsa kulosera kwapampu. Chifukwa chake, m'mimba mwake mwachiwongolero sikucheperachepera 70% ya kukula kwake koyambirira.

M'mapampu ena, kudula kochititsa chidwi kumawonjezera mutu wa net positive suction (NPSHR) wofunidwa ndi mpope. Pofuna kupewa cavitation, mpope wa centrifugal uyenera kugwira ntchito movutikira panjira yake (ie NPSHA ≥ NPSHR). Kuti muchepetse chiwopsezo cha cavitation, zotsatira za kudula kwa impeller pa NPSHR ziyenera kuyesedwa pogwiritsa ntchito deta ya wopanga pamitundu yonse yogwirira ntchito.
