Kuchengetedza vharuvhu yekubuditsa mvura yakavharwa panguva yekubudaPombi dzeCentrifugalmashandiro acho anounza njodzi dzakawanda dzehunyanzvi.
Kushandurwa kwesimba kusingadzoreki uye kusawirirana kwethermodynamic
- 1.1 Kana tembiricha yepakati yakavharwa, simba rese rinopinda rinoshandurwa kuita simba rekupisa. Tembiricha haikwanise kubvisa kupisa, zvichiita kuti tembiricha iri mukamuri repombi ikwire zvakanyanya. Kushanda nguva dzose kuchaita kuti simbi ipfuure, zvichiita kuti zvinhu zvinovhara zviwedzere kupisa.
1.2 Kukundikana kwesystem yekuvhara Munzvimbo ine tembiricha yakakwira uye kupiswa kwechinhu chinonyungudika, chinhu chinonyungudika chinoshandisa mafuta ekuzora uye kutonhora kwechinhu chinonyungudika chinoita kuti chinhu chinonyungudika chisashande zvakanaka - chinhu chinonyungudika chichava nekukweshana kwakaoma uye chiso chechinonyungudika chichapiswa.
Kushushikana kwemakemikari kusina kujairika
- 2.1 Kupfuura simba reAxial Simba revharuvhu rinovhara rinowanzo kuve rakapetwa ka1.5-5 pane mamiriro ekushanda akajairika, uye mutoro wekutakura unogona kusvika kana kutopfuura muganho wawo wekutakura, zvichikonzera kupatsanuka kwekeji rekutakura kana kushanduka kwekeji.
2.2 Kudedera uye kukuvara kwekuneta Musiyano wekuwedzera kwekupisa kunokonzerwa nekupisa kwakanyanya unotungamira mukushanduka kwekupisa kana kushushikana kwekupisa, mukaha usina kujairika pakati peimpeller nepombi, uye simba remutoro we hydraulic usina kuenzana, izvo zvinoita kuti dynamic balance ye rotor ikuvadzwe, vibration inowedzera, uye zvikamu zvinokuvadzwa nekuneta.
Kukuvadzwa kweganda uye kukuvara kwezvinhu
3.1 NPSH allowance inverted medium vaporization [inoita kuti cavitation allowance (NPSHa) yechishandiso ive yakaderera pane NPSHr inodiwa yepombi], zvichigadzira mabubbles, uye shock wave inokonzerwa nekudonha kwemabubbles inogona kusvika 690MPa, zvichikonzera kudonha kwenzvimbo ye impeller.
3.2 Kuora kwechimiro chesimbi. Kune vanopinza simbi isina tsvina vanonzwa kugadzikana kana tembiricha yakakwira, uye mwero wekuora pakati pegranular uchawedzera uye simba rekudhonza richadzikira. Kune vanopinza simbi ine kabhoni, matambudziko patembiricha yakakwira anonyanya kukosha, akadai sekuoxidation nekubvisa kabhoni mutembiricha yakakwira, zvichikonzera kudzikira kwesimba repamusoro uye mitemo yakajairika; Kana iine tsvina yakaita sesarufa nephosphorus, zviri nyore kuiparadzanisa pamiganhu yezviyo patembiricha yakakwira, zvichikonzera brittleness yekupisa uye kutsemuka nyore panguva yekushanda; Kana tembiricha yakakwira kwenguva refu, simbi ine kabhoni isingakwanise kudzika, uye tembiricha yakakwira yemutembiri inogona kukurumidzisa creep deformation, izvo zvinozopedzisira zvaita kuti impeller iputsike kana kuti isashande zvakanaka.
Kuchengetedzeka kwehurongwa uye njodzi dzehupfumi
4.1 Kumanikidzwa kwesimba reganda rinobata kumanikidzwa kunodarika muganho uye kushanda kwevharuvhu rinovhara kunoita kuti simba rekubuda kwepombi risvike 120-150% yemutengo wakayerwa, uye pane njodzi yekupfuura nekumanikidzwa kwakatarwa kwevharuvhu rekuchengetedza, izvo zvinogona kukonzera kusunungurwa kwekumanikidzwa kana kutsemuka kweweld yepombi.
4.2 Kushandiswa kwesimba uye mari yekugadzirisa kuwedzera Kuvhara mavharuvhu ndiko "kunouraya" kwepombi dze centrifugal, izvo zvinowedzera zvakanyanya kushandiswa kwesimba munguva pfupi, uye kushanda kwenguva refu kunotungamira mukukuvadzwa kwakaipa kwemidziyo, uye mutengo wekugadzirisa wakakwana unogona kuwedzera nekatatu kusvika kagumi.
Kushata kwemamiriro ekushanda enhau dzakakosha
Kune volatile media (semuenzaniso, LPG), kushanda kwevharuvhu yakavharwa kuchakurumidzisa kupfuta kwechikamu chemvura, uye kuyerera kwegasi-mvura muchikamu chepombi kunokonzera shanduko dzemvura kamwe kamwe, zvichikonzera kutenderera kwemasimba emagetsi nguva nenguva uye kukurumidzisa kupfeka kwezvikamu.
Ruzivo muindasitiri uye zvinodiwa zvakajairwa
6.1 Ruzivo muindasitiriZvichienderana neruzivo rwekushandisa mainjiniya chaiwo, nguva yekumhanya kwevharuvhu yepombi yecentrifugal haifanirwe kudarika maminetsi maviri, uye inowanzo ganhurira kuminiti imwe. Zvinokurudzirwa kugadzira sisitimu yekudzora kukiya kuti itange otomatiki chirongwa chekudzivirira kudzima kana vharuvhu yekubuda yavhara uye nguva dzakawedzerwa.
6.2 Zvinodiwa kuti API 610 12th Edition standard itaure kuti mamwe mapombi ane simba rakawanda, akagadzirwa zvakanaka kana kuti ane matanho akawanda anokwira tembiricha nekukurumidza kana vharuvhu yekubuditsa yavharwa, izvo zvinoita kuti kuyedza kusagoneke uye/kana kusachengeteka kana vharuvhu yavharwa. Kukwira kwetembiricha kwakabatana zvakanyanya nehuremu hwesimba. Huremu hwesimba PD, iyo inogona kufungidzirwa se:
P yakayerwa: Simba rechikamu chimwe nechimwe kana mvura iri muhp (kana MW)
D imp: Yakayerwa dhayamita ye impeller mu in. (kana m)
Nhubu D: Dhayamita yeflange inobuda nepakati (kana m). Kune pombi dzinodhonza kaviri, dzine danho rimwe chete, nhubu D ndiyo dhayamita yeflange inopinza.
Kukosha kwakajairika kwePD i0.286 hp/in.3 (13 MW/m3), pamusoro pazvo zvinokurudzirwa kusashandisa pombi nevharuvhu yekubuditsa yakavharwa panguva yekuedzwa kwekushanda.
