Mapangidwe ndi mfundo zogwirira ntchito zamapampu oyimirira ambiri

Mapampu a Multistage ndi zida zapamwamba zogwirira ntchito zamadzimadzi zomwe zimapangidwira kuti zipereke ntchito yothamanga kwambiri pogwiritsa ntchito ma impeller angapo mkati mwa pampu imodzi. Mapampu a Multistage amapangidwa kuti azigwira bwino ntchito zosiyanasiyana zomwe zimafuna kuthamanga kwapamwamba, monga madzi, njira za mafakitale, ndi machitidwe otetezera moto.

Kapangidwe kaMapampu a Vertical Multistage

Mapangidwe a Purity vertical multistage pump amatha kugawidwa m'zigawo zinayi zazikulu: stator, rotor, bearings, ndi shaft seal.
1. Stator: Thepompa centrifugalstator imapanga pachimake pazigawo zoyima za mpope, zomwe zimakhala ndi zinthu zingapo zofunika. Izi zikuphatikizapo suction casing, gawo lapakati, discharge casing, ndi diffuser. Zigawo zosiyanasiyana za stator zimamangirizidwa bwino pamodzi ndi ma bolts, kupanga chipinda chogwira ntchito cholimba. Pampu centrifugal suction casing ndi pamene madzimadzi amalowa mu mpope, pamene casing zotayira ndi kumene madzimadzi amatuluka pambuyo kupeza mphamvu. Chigawo chapakati chimakhala ndi mavane otsogolera, omwe amathandiza kuyendetsa bwino madzimadzi kuchokera pagawo lina kupita ku lina.
2.Rotor: Thepampu yoyima ya centrifugalrotor ndi gawo lozungulira la pampu ya centrifugal ndipo ndilofunika kuti ligwire ntchito. Zimapangidwa ndi shaft, impellers, balancing disc, ndi manja a shaft. Shaft imatumiza mphamvu yozungulira kuchokera ku injini kupita ku zotulutsa, zomwe zimapangitsa kuti madziwo azisuntha. Zotulutsa, zomwe zimayikidwa pa shaft, zimapangidwa kuti ziwonjezere mphamvu yamadzimadzi pamene ikuyenda pa mpope. Diski yofananira ndi gawo lina lofunikira lomwe limalimbana ndi kukwera kwa axial komwe kumachitika pakagwira ntchito. Izi zimatsimikizira kuti rotor imakhalabe yokhazikika ndipo mpope imagwira ntchito bwino. Manja a shaft, omwe ali kumapeto kwa shaft, ndi zinthu zosinthika zomwe zimateteza shaft kuti isawonongeke.
3.Bearings: Miyendo imathandizira shaft yozungulira, kuonetsetsa kuti ntchito yosalala ndi yokhazikika. Mapampu opindika ambiri amagwiritsa ntchito mitundu iwiri ya ma fani: ma bearings ogudubuza ndi ma sliding bearings. Mapiritsi ozungulira, omwe amaphatikizapo kunyamula, nyumba zokhala ndi kapu, ndi mafuta odzola ndipo amadziwika chifukwa cha kulimba kwawo komanso kugunda kochepa. Komano, mayendedwe otsetsereka amapangidwa ndi chivundikiro, chivundikiro, chipolopolo, chivundikiro cha fumbi, choyezera kuchuluka kwa mafuta, ndi mphete yamafuta.
4.Shaft Seal: Chisindikizo cha shaft ndichofunika kwambiri popewa kutuluka komanso kusunga kukhulupirika kwa mpope. M'mapampu osunthika osunthika, chosindikizira cha shaft nthawi zambiri chimagwiritsa ntchito chisindikizo. Chisindikizochi chimapangidwa ndi manja osindikizira pabokosi loyamwa, kulongedza, ndi mphete yosindikizira madzi. Zopakirazo zimapakidwa mwamphamvu kuzungulira shaft kuti madzi asatayike, pomwe mphete yosindikizira yamadzi imathandizira kuti chisindikizocho chikhale chogwira ntchito pochisunga kuti chikhale chofewa komanso chozizira.

Mfundo Yogwirira Ntchito ya Vertical Multistage Pampu

Mapampu ophatikizika amitundu yambiri amagwira ntchito motengera mfundo ya mphamvu yapakati, lingaliro lofunikira mumayendedwe amadzimadzi. Opaleshoniyo imayamba pamene galimoto yamagetsi imayendetsa tsinde, zomwe zimapangitsa kuti ma impellers omwe amamangiriridwapo azizungulira kwambiri. Pamene ma impellers amazungulira, madzimadzi mkati mwa mpope amayendetsedwa ndi mphamvu ya centrifugal.
Mphamvu imeneyi imakankhira madziwo kunja kuchokera pakati pa choponderezacho kupita m’mphepete, kumene amapeza mphamvu ndi liwiro. Kenako madziwa amadutsa m’mipando ya kalozera n’kukafika pagawo lina, kumene amakumana ndi chopondereza china. Izi zimabwerezedwa m'magawo angapo, ndipo choyikapo chilichonse chimawonjezera mphamvu yamadzimadzi. Kuwonjezeka kwapang'onopang'ono kwapang'onopang'ono pazigawo zonse ndizomwe zimapangitsa kuti mapampu a multistage azitha kugwira ntchito zothamanga kwambiri.
Mapangidwe a ma impellers ndi kulondola kwa mavane otsogolera ndizofunikira kwambiri kuti madzi amadzimadzi aziyenda bwino pagawo lililonse, kupeza kupanikizika popanda kutaya mphamvu kwakukulu.
