Thepompu yoyimirirainjini inasintha makampani opanga mapompi kumayambiriro kwa zaka za m'ma 1920 mwa kulola kuti ma mota amagetsi azilumikizidwa pamwamba pa pampu, zomwe zinapangitsa kuti pakhale zovuta zazikulu. Izi zinapangitsa kuti njira yoyikira ikhale yosavuta komanso kuchepetsa ndalama chifukwa cha kufunika kwa zigawo zochepa. Kugwira ntchito bwino kwa ma mota a pampu kunawonjezeka ndi 30%, ndipo cholinga cha ma mota a pampu oyima chinawapangitsa kukhala olimba komanso odalirika poyerekeza ndi ena opingasa.
Ma mota opompa ozungulira nthawi zambiri amagawidwa m'magulu kutengera mtundu wa shaft yawo, kaya yopanda kanthu kapena yolimba.
Pampu yoyimirira yopanda kanthu (VHS)Ma mota ndi ma mota a pampu a vertical solid shaft (VSS) ali ndi kusiyana kosiyanasiyana pa kapangidwe ndi kagwiritsidwe ntchito kawo. Nazi zina mwa kusiyana kwakukulu:
1. Kapangidwe ka Shaft:
-Ma mota a pampu a VHSIli ndi shaft yopanda kanthu, yomwe imalola shaft ya pampu kudutsa mu mota kuti ilumikizane mwachindunji ndi impeller. Kapangidwe kameneka kamachotsa kufunikira kolumikizana kosiyana ndikuchepetsa kutalika konse kwa msonkhano wa pampu ndi mota.
-Ma mota a VSS pampuIli ndi shaft yolimba yomwe imachokera ku mota kupita ku impeller. Kutambasula kwa shaft nthawi zambiri kumakhala ndi keyway yozungulira yotumizira kupopera kwa pampu ndi keyway yozungulira yotumizira torque. Kulumikizana kwa malekezero apansi pakati pa mota ya pampu ndi shaft ya pampu kumachitika kawirikawiri m'matanki ndi mapampu osaya, mosiyana ndi ntchito za chitsime chozama.
2. Kugwiritsa ntchito:
- Ma mota a pampu a VHS amagwiritsidwa ntchito kwambiri m'zitsime zakuya komanso m'mapampu olowa pansi pomwe shaft ya pampu imafikira m'chitsime kapena m'sump.
- Ma mota a pampu a VSS nthawi zambiri amagwiritsidwa ntchito m'malo omwe shaft ya pampu sikufunika kufalikira m'chitsime kapena m'chitsime, monga mapampu olowera kapena malo omwe pampu ili pamwamba pa mulingo wa madzi.
3. Kukonza:
- Ma mota a pampu a VHS angakhale osavuta kusamalira ndi kukonza chifukwa cha kulumikizana mwachindunji pakati pa mota ndi shaft ya pampu. Komabe, kupeza mota kuti ikonzedwe kungakhale kovuta kwambiri chifukwa cha malo ake m'chitsime kapena m'chitsime.
- Ma mota a pampu a VSS angafunike kukonzedwa pafupipafupi kwa kulumikizana pakati pa mota ndi shaft ya pampu, koma mota yokha ingakhale yosavuta kuyigwiritsa ntchito.
Zokhudza Ma Vertical Hollow Shaft Motors: Kodi Ma Hollow Motors ndi Antchito Yanji?
Ma mota a Vertical hollow shaft (VHS) amapangidwira ntchito zinazake pomwe shaft ya pampu imafikira m'chitsime kapena m'chitsime.
Poyamba, mapampu a pamwamba pa nthaka ankagwiritsidwa ntchito pothirira m'malo ouma koma abwino kwa ulimi, monga California. Mapampuwa anali ndi magiya olunjika kumanja ndipo ankayendetsedwa ndi injini zoyatsira moto mkati. Kuyambitsidwa kwa ma mota amagetsi pamwamba pa mapampu kunachotsa kufunikira kwa bokosi lamagetsi kuti lipereke ma torque ndi ma bearings akunja kuti pakhale kupopera kwapadera kwa pampu. Kuchepa kwa zida kumeneku kunapangitsa kuti ndalama zichepe, kukula kochepa, kuyika kosavuta, komanso ziwalo zochepa. Ma mota a pampu oyenda pansi amagwiranso ntchito bwino pafupifupi 30% kuposa ma mota opingasa ndipo adapangidwira ntchitoyi, zomwe zimapangitsa kuti pampu ikhale yolimba komanso yodalirika. Kuphatikiza apo, adapangidwa kuti apirire mikhalidwe yosiyanasiyana yachilengedwe. Zotsatira zake, ulimi ku California unatha kukulirakulira pansi pa mikhalidwe iyi.
Kodi ndiyenera kusankha mota ya Solid Shaft kapena Hollow Shaft kuti ndigwire ntchitoyo?
Kusankha mota yolimba kapena hollow shaft yoyenera pa ntchito inayake kumadalira zofunikira pa ntchitoyo komanso momwe zinthu zilili. Ma mota olimba nthawi zambiri amagwiritsidwa ntchito pogwiritsira ntchito pomwe shaft ya pampu sikufunika kufalikira mu chitsime kapena sump, monga mapampu omwe ali pamzere kapena kuyika pamwamba pa nthaka. Kumbali inayi, ma mota obowola ndi oyenera kugwiritsa ntchito pampu yozama komanso yobowola pansi, komwe shaft ya pampu imafalikira mu chitsime kapena sump.
Kuwonjezera pa zofunikira monga mphamvu ya akavalo, liwiro, malo ozungulira, mphamvu yolowera, ndi kukula kwa chimango komwe kumagwirizanitsidwa ndi ma induction motors onse, ma vertical hollow shaft (VHS) motors alinso ndi zofunikira zinazake zoyendetsera. Mphamvu yoyendetsera galimoto iyenera kupitirira mphamvu zonse za axial zomwe idzakumane nazo, kuphatikizapo kulemera kwa rotor, shaft ya pampu ndi impeller, ndi mphamvu zamagetsi zomwe zimafunika kuti madziwo anyamulidwe pamwamba.
Pali njira zitatu kapena njira yoyendetsera: ma motors oyendetsera bwino, ma motors oyendetsera apakatikati, ndi ma motors oyendetsera okwera. Mota yopingasa imaonedwa kuti ndi mota yoyendetsera bwino ndipo ndi yoyenera kugwiritsidwa ntchito nthawi zonse pomwe mphamvu yochepa yakunja imagwiritsidwa ntchito pa bearing ya mota.
Mota yapakati yopukusa, yomwe imadziwikanso kuti mota ya pampu yolumikizidwa, idapangidwira ntchito zinazake ndipo imaonedwa kuti ndi mota yofunikira. Ma impeller amayikidwa mwachindunji pa shaft ya mota, ndipo chogwirira cha thrust nthawi zambiri chimakhala pansi kuti kutentha kwa rotor kusakhudze malo otseguka a impeller. Kulekerera kwa shaft ya mota ndi flange run-out ndikofunikira, chifukwa magwiridwe antchito a impeller amadalira kulekerera kwapafupi ndi nyumba ya pampu.
Mota yothamanga kwambiri imatha kusinthidwa mosavuta ndi wopanga ndipo nthawi zambiri imapereka ma thrust a 100%, 175%, kapena 300%, ndipo thrust bearing nthawi zambiri imakhala pafupi ndi pamwamba.
Ngati mukufuna thandizo posankha mota yoyenera ntchito yanu, musazengereze kulankhulana ndi katswiri wa ku Tkflo. Tikusangalala kuyankha mafunso aliwonse omwe mungakhale nawo okhudza kusankha mota yoyenera yokhala ndi vertical hollow shaft kutengera zosowa zanu.
Kodi Mapulogalamu Ogwiritsira Ntchito Ndi Otani?Mapampu Oyimirira a Turbine?
Ntchito za Mapampu Ozungulira a Turbine zikuphatikizapo ntchito zosiyanasiyana pakupereka madzi, kuthirira, ntchito zamafakitale, ndi njira zamadzi za m'mizinda. Amagwiritsidwa ntchito pothirira ulimi, kusamutsa madzi m'njira zoperekera madzi m'mizinda, komanso njira zamafakitale monga kuzizira kwa madzi ndi kukonza madzi otayira.
Pampu ya turbine yoyima (VTP) ndi mtundu wa pampu yamagetsi yozungulira yokhala ndi radial kapena radial flow impeller yabwino. Mapampu awa nthawi zambiri amakhala ndi magawo ambiri, okhala ndi milingo yambiri ya impeller mkati mwa mbale, ndipo amatha kugawidwa m'magulu monga mapampu a zitsime zakuya kapena mapampu afupiafupi.
Turbine ya chitsime chozama nthawi zambiri imayikidwa m'chitsime chobowoledwa, ndipo chitoliro choyamba chimayikidwa pansi pa madzi a pampu. Mapampu awa amadzipangira okha, nthawi zambiri amakhala ndi magawo ambiri, ndipo amagwiritsidwa ntchito makamaka ponyamula madzi. Ntchito yawo yayikulu imaphatikizapo kunyamula madzi kuchokera ku zitsime zozama kupita pamwamba.
Mapampu amenewa amatumiza madzi ku malo oyeretsera madzi, makina othirira madzi, ndi mipope ya m'nyumba. Mapampu afupiafupi amagwira ntchito mofanana ndi mapampu a m'zitsime zozama, omwe amagwira ntchito m'madzi osaya kwambiri okhala ndi kuya kwakukulu kwa mamita 40.
Pompu ya VTP ikhoza kuyikidwa mu mbiya yopopera kapena pansi pa nthaka kuti iwonjezere mitu yopopera ya impeller yoyamba. Mapampu awa nthawi zambiri amagwiritsidwa ntchito ngati mapampu owonjezera kapena m'malo ena komwe mutu wopopera wotsika (NPSH) umapezeka.
Kutha kwawo kuthana ndi kuchuluka kwa madzi otuluka komanso kugwira ntchito bwino m'malo ovuta kumawapangitsa kukhala oyenera kugwiritsidwa ntchito m'njira zosiyanasiyana, kuphatikizapo zomwe zimafuna kuperekedwa kwa madzi amphamvu.
