Cholowacho chimatanthawuza chimbale cha gudumu chokhala ndi masamba oyenda. Mu mpope wa centrifugal, choyikapo chikutanthauza thupi lozungulira lomwe lili ndi masamba omwe amasamutsa mphamvu kupita kumadzimadzi.
Masamba a centrifugal pump impellers nthawi zambiri amakhala masamba okhota kumbuyo. Pali mitundu iwiri ya masamba: cylindrical ndi zopindika. Kugwiritsiridwa ntchito kwa masamba opotoka kungathe kuchepetsa katundu wa masamba, kupititsa patsogolo kuyamwa kwa pampu ya centrifugal, ndi kupititsa patsogolo luso la anti-cavitation, koma kupanga kumakhala kovuta ndipo mtengo wake ndi wokwera.
Pampu yapakati yoyenga ndi makampani opanga mankhwala imafuna kuti choyikapocho chiziponyedwa kapena chowotcherera kwathunthu. Kukula kwa ma welded impellers nthawi zambiri amagwiritsidwa ntchito pamapampu apadera a centrifugal opangidwa ndi zinthu zachitsulo zokhala ndi zinthu zosafunikira (monga chitsulo ndi ma aloyi ake). Kulondola kwa geometric ndi kutsirizitsa kwapamwamba kwa choyikapo chowotcherera ndikwabwino kuposa cha chopondera, chomwe chimapindulitsa kupititsa patsogolo mphamvu ya mpope wa centrifugal.
Malinga ndi njira processing, choyambitsa akhoza kugawidwa mu mtundu riveted, welded mtundu ndi yofunika. The integrally anapanga impeller makamaka amatanthauza mwatsatanetsatane kuponya ndondomeko ndi zina zapaderazi. Themwatsatanetsatane kuponyera ndondomekoamapulumutsa maola ndi zipangizo zonse, koma chifukwa cha mawonekedwe ovuta a choipitsa ndi zofunikira zowonongeka, zimakhala zovuta kuonetsetsa kuti zoponyera zopanda pores ndi zonyansa.
Chithunzi cha RMCamatha kupanga mitundu yosiyanasiyana ya ma impellers pogwiritsa ntchito njira yolondola yopangira (kuponya ndalama) komansoCNC mwatsatanetsatane makina. Titha kupanga zopatsira zolondola kwambiri, zolimbana ndi dzimbiri kuchokera ku chitsulo chosapanga dzimbiri cha austenitic, chitsulo chosapanga dzimbiri cha duplex, mpweya wowuma chitsulo chosapanga dzimbiri, ndi ma aloyi opangidwa ndi faifi tambala.
Pakalipano, mitundu yoyambira ya centrifugal pump impellers ndi mtundu wa njira yotuluka (njira imodzi yokha, njira yothamanga iwiri), mtundu wa vane (mtundu wotsekedwa, mtundu wotseguka), mtundu wa spiral centrifugal ndi mtundu wa swirl.
1. Channel Type Impeller
The flow channel impeller ndi njira yokhotakhota yotuluka kuchokera polowera kupita ku potulukira. Mtundu woterewu ndi woyenera kunyamula zakumwa zomwe zili ndi tinthu tambiri tonyansa kapena ulusi wautali. Chifukwa mtundu uwu wa impeller uli ndi anti-clogging katundu wabwino kwambiri. Koma choyipa chake ndikuti ntchito yotsutsa-cavitation ndi yofooka kuposa mitundu ina.
2. Vane Impeller
Bipwilo bivule bivule mu bilongwa byetu bikokeja kutamija, ne kwingidija ne kulongolola mwanda wa kwingidila mu mwingilo wa kusapula. Komabe, kuipa kwake ndikuti kusiyana pakati pa khoma lamkati lamadzi oponderezedwa ndi tsamba pansi pa abrasion ya tinthu tating'onoting'ono kumawonjezeka panthawi yoyendetsa, zomwe zimachepetsa magwiridwe antchito a mpope, komanso kukhazikika kwa kayendedwe ka madzi. m'mphepete mwa njirayo imawonongeka chifukwa cha kuchuluka kwa kusiyana. , kupanga mpope kugwedezeka, mtundu uwu wa choyikapo si zophweka kunyamula sing'anga munali tinthu lalikulu ndi ulusi wautali. Chotsekera chotsekedwa chimakhala ndi magwiridwe antchito apamwamba ndipo chimatha kuyenda bwino kwa nthawi yayitali. Axial thrust ya mpope ndi yaying'ono, koma chotchinga chotsekedwa chimakhala chosavuta kuvulala, ndipo sizovuta kunyamula zonyansa zokhala ndi tinthu tating'ono kapena ulusi wautali.
3. Spiral Centrifugal Impeller
Ma Spiral centrifugal impellers ali ndi masamba opindika omwe amatambalala kuchokera padoko loyamwa pamutu wopindika. Madzi otumizidwa sangagunde mbali iliyonse ya mpope pamene akuyenda muzitsulo, kotero palibe kuwonongeka kwa mpope, ndipo panthawi imodzimodziyo, sikuwononga madzi otumizidwa. Chifukwa cha kuthamangitsidwa kwa wononga, tinthu tating'onoting'ono timakhala ndi mphamvu yodutsa, kotero mtundu uwu umatengedwa. Mapampu a impeller ndi oyenera kupopera media okhala ndi tinthu tating'onoting'ono ndi ulusi wautali.
4. Swirl Impeller
Chiwongolero chogwedezeka ndi zonse kapena gawo la chiwongolero chomwe chimabwereranso ku njira yothamanga ya chipinda chamadzi chopanikizika, chomwe chimakhala ndi ntchito yabwino yotsutsana ndi kutseka. The particles kuyenda mu madzi kuthamanga chipinda pansi nyonga ya vortex kwaiye ndi kasinthasintha wa impeller, ndi kayendedwe ka inaimitsidwa particles si kupanga mphamvu, ndi kusinthanitsa mphamvu ndi madzi mu otaya njira. Panthawi yothamanga, tinthu tating'onoting'ono kapena ulusi wautali sizimalumikizana ndi masamba ovala, masambawo amavala kwambiri, ndipo kusiyana sikukukulirakulira chifukwa cha abrasion. Ndizoyenera kupopera zofalitsa zomwe zili ndi tinthu tating'onoting'ono komanso ulusi wautali.
Makapu omwe amagwiritsidwa ntchito pamapampu apakati amatha kugawidwa m'njira zinayi: (a) mtundu wotsekedwa; (b) kutsogolo theka lotseguka mtundu; (c) mtundu wakumbuyo wotseguka; (d) mtundu wotseguka
1. Chotsekera chotsekedwa
Chotsekera chotsekedwa chimakhala ndi masamba ndi mbale zakutsogolo ndi zakumbuyo. Chotseketsa chotsekedwa chimakhala ndi mphamvu zambiri ndipo n'zovuta kupanga, ndipo chimagwiritsidwa ntchito kwambiri pamapampu a centrifugal. Ndioyenera kunyamula zakumwa zoyera zokhala ndi mamasukidwe ochepa komanso opanda tinthu ting'onoting'ono, monga madzi aukhondo ndi mayankho.
2. Semi-otseguka cholowera
The theka-otseguka choyikapo nthawi zambiri amakhala ndi zinthu ziwiri: imodzi ndi yapatsogolo yotseguka, yomwe imapangidwa ndi mbale yakumbuyo yakumbuyo ndi masamba. Mphamvu yamagetsi yamtunduwu ndi yotsika, ndipo mphete yosindikizira yokhala ndi chilolezo chosinthika imafunika kuti ikhale yabwino; chinacho ndi mbale yakumbuyo ndi mpeni. Mtundu wa semi-otseguka umakhala ndi mbale yakutsogolo yakutsogolo ndi tsamba. Popeza kuti mphete yosindikizira imodzimodziyo monga choyikapo chotsekedwa chikhoza kuikidwa, mphamvu yake imakhala yofanana ndi yotsekera yotsekedwa, ndipo tsambalo limakhalanso ndi (tsamba lakumbuyo kapena chothandizira chothandizira) kuwonjezera pa kutumiza madzi. zotsatira. The theka-otseguka impeller ndi yoyenera kunyamula zakumwa zomwe zili ndi zolimba zoyimitsidwa monga tinthu tolimba ndi ulusi. The semi-open impeller sizovuta kupanga, zotsika mtengo, ndipo zimakhala ndi mphamvu zosinthika.
3. Tsegulani chowongolera
Choyambitsa chotseguka chimakhala ndi masamba okha ndi nthiti zolimbitsa masamba, ndipo palibe chopondera chokhala ndi mbale zakutsogolo ndi zakumbuyo. The impeller ali otsika dzuwa ndi ntchito zochepa, ndipo makamaka ntchito kunyamula zakumwa ndi mkulu mamasukidwe akayendedwe ndi slurry zakumwa.
