Chigadzirwa Nhanganyaya
Iyo screw pombi inoyamwa uye inoburitsa mvura kuburikidza nesikuru kutenderera. Iyo yepakati sikuruu ndeye inoshanda shinda, iyo inotyairwa ne prime mover. Izvo zvipenga pamativi ese ari maviri anotyairwa screws, uye iwo anotenderera achidzoka neanoshanda sikuruu. Ose ari maviri mashandiro uye anotyairwa tambo tambo akapetwa-apera. Nekuda kwekupindirana kwemhepo uye kukwana kwakaringana kwekutenderera nemadziro emukati eiyo liner, nhevedzano yenzvimbo dzakavharwa dzakawanda dzinoumbwa pakati pekukweva nekubuda pombi. Nekutenderera uye kubatanidzwa kweiyo screw, inoramba ichivharwa nzvimbo inoumbwa panoteedzera pombi, iyo mvura mukamuri yekukwevera yakavharidzirwa imomo, uye inoenderera ichisundidzirwa pamwe nekamuri yekukwevera kune iyo yekubuda kumagumo mune inonoka axial nzira . Inoenderera uye ichitsetsenura inoburitsa mvura yakavharirwa munzvimbo dzakasiyana, sekunge nzungu dzairamba dzichisundirwa kumberi apo kutenderera kuri kutenderera. Ndiwo musimboti wekushanda musimboti weiyi nongedzo mbiri pombi.
Screw Pump Zvimiro:
1.Iyo yekuvharira chisimbiso mutsetse wakasangana neiyo rotor yeiyo stator inoparadzanisa zvachose suction kamuri kubva kune inobuda mukamuri, kuitira kuti iyo pombi iite zvakafanana basa sevhavha;
Inogona kuendesa midhiya-chikamu midhiya yemvura, gasi uye yakasimba.
3.Iyo vhoriyamu haichinje kana iyo fluid iri mupombi ichiyerera, hapana mhirizhonga inomutsa uye pulsation;
4.Iyo vhoriyamu kamuri inoumbwa neiyo yakasununguka stator inogona kunyatso kudzora kupfeka kwepakati iine yakasimba zvikamu;
5.Iyo yekuisa yepakati viscosity inosvika ku50: 000Mpa s, solid kusvika ku50%;
6.Yero yekuyerera inoenderana nekumhanya, uye nagavhuna, inogona kugadzirisa otomatiki kuyerera, uye zvese zviri zviviri kumberi uye kumashure dhirivhari zvinotenderwa.
Iyo screw pombi ine zvinotevera zvakanakira:
• Inofananidzwa nepombi centrifugal, iyo pombi yekumusoro haidi kuisa iyo vharuvhu, uye kuyerera r kwakadya ndiko kugadzikana kwemitsetse kuyerera;
• Inofananidzwa nepombi plunger, iyo pombi yekumusoro ine yakasimba-yekuzvidzora kugona uye yepamusoro yekukweva kukwirira;
• Inofananidzwa nepombi yedhiramu, iyo pombi yekumusoro inogona kutakura mhando dzese dzakasanganiswa tsvina, senge yepakati ine gasi uye yakasimba tuta kana tambo, uye inogona zvakare kutakura zvinhu zvakasiyana zvinokanganisa;
• Inofananidzwa nemapombi epombi, mapampu epururu anogona kununura zvakanyanya viscous media;
• Kusiyana nemapombi episton, epombi yedhiaphragm nemapombi egiya, mapampu epurufu anogona kushandiswa kuzadza uye kuyera mishonga yemishonga.
Kushanda Musimboti
Iyo screw pombi ipombi-yerudzi yekumhanyisa pombi. Izvo zvakakosha zvinhu irotor uye stator. Iyo rotor iguru-lead, hombe-zino-kureba, uye diki-helix yemukati-dhayamita sikuruu, uye iyo stator inowirirana ine misoro miviri-inotenderera inokora uye sleeve, iyo inoumba nzvimbo yeiyo yekuchengetedza svikiro pakati peiyo rotor uye stator . Kana iyo rotor iri kushanda mu stator, iyo yepakati inofamba axially kubva pakutsveta kumagumo kusvika pakubuda kufamba.
Iyo screw pombi ine zvinotevera zvakanakira:
I. Nzvimbo dzakasiyana dzekumanikidza uye kuyerera. Iko kumanikidza kuri nezve 3.4-340 kgf / cm2 uye kuyerera kwacho kuri 1,8600 cm3 / m;
2.Wide mhando yemhando uye viscosities yezvinoburitsa zvinwiwa;
3.Iine yekumhanyisa kumhanya nekuda kwenzvimbo yepasi inertia yezvikamu zvinotenderera mupombi
4.With kuzvidzora-priming kugona, kwakanaka kubvisa kuita ,;
5.Uniform kuyerera, pasi kudengenyeka, pasi ruzha;
6.Less inonzwisisa kune inouya gasi uye tsvina kana ichienzaniswa nedzimwe pombi dzinotenderera,
7.A yakasimba mamiriro, nyore kuisa uye kugadzirisa.
Iko kusakosha kweiyo screw pombi ndeyekuti iyo sikuru inoda yakakwirira kugadzira uye kuungana; mashandiro epombi anonzwisisa shanduko muiyo viscosity yemvura.
Chigadzirwa Showcase
Zvakajairika Zvikanganiso Uye Mhinduro
1 Iyo pombi haishande:
Zvimwe zvinogona kukonzera: Rotor uye stator zvakanyanyisa; iyo voltage yakanyanya kuderera; iyo viscosity yepakati yakanyanya kukwirira.
Solution: Tenderedza pombi kashoma nematurusi uye nesimba, gadzirisa kumanikidza; sanganisa vezvenhau.
2.Iyo pombi haina kuyerera kunze:
Zvinokonzeresa: nzira isiriyo yekutenderera; matambudziko netubhu yekukweva; yakanyanya kukwirira viscosity yepakati; iyo rotor, stator, kana zvikamu zvekutapurirana zvakakanganiswa;
Solution: Chinja iko kutenderera kutenderera; tarisa kubvuuka, yakavhurika yekupinda uye yekubuditsa mavharuvhu; sanganisa media; ongorora uye kutsiva zvikamu zvakakanganiswa;
3.Kushayikwa kwekuyerera:
Zvimwe zvinogona kukonzera: pombi dzinodonha. mavhavha haana kuvhurika zvakakwana kana kudzivirirwa zvishoma; yakaderera kushanda kumhanya; kupfeka kwe rotors uye stators.
Kugadzirisa: Tarisa nekugadzirisa mapaipi; vhura magedhi ese, bvisa plugs; chinja kumhanya; kutsiva zvikamu zvakakanganisika
4.Kushaya kumanikidza:
Possible zvikonzero: Worn rotor uye stator.
Solution: Tsiva iro rotor, stator
5.Motor kupisa:
Zvinogona kuitika: mota kutadza; kuwedzeredza kuburitsa kumanikidza, mota kuwandisa, uye kukuvara kwemotokari. Solution: Tarisa mota uye uzvinetse; chinja iyo yekuvhura vharuvhu yekugadzirisa kumanikidza; tsiva chikamu chakakuvadzwa.
6.Flow kumanikidza anodonhedza zvakanyanya:
Zvimwe zvinogona kukonzereswa: Kuvhara kamwe-kamwe kana kudonha kwedunhu; kupfeka kwakakomba kweiyo stator; kamwe-kamwe shanduko mune viscosity yemvura; kamwe kamwe kudonha kwemagetsi.
Solution: Bvisa plugged kana chisimbiso chubhu; kutsiva stator rabha; chinja fluid viscosity kana mota simba, gadziridza voltage.
7.A yakawanda nhamba inodonha mvura pane iyo shaft chisimbiso: Zvinogona kuitika: zvakapfava zadza kupfeka Solution: Dhinda kana kutsiva iyo yekuzadza.
Kuisa Mirayiridzo
Chenjerera kutenderera kwekutenderera kwemota kudzivirira kutenderera kutendeuka.
Mapaipi ari nyore kubvisa ane hurefu hwakati kurei pane stator anofanirwa kuiswa pasiti yemvura kufambisa stator.
• Chengetedza pombi inopinda munzira yakatwasuka, nzira yekubuda munzira yakatwasuka, kuitira kuti chisimbiso chigone kushanda munzvimbo yekumanikidza, zvichideredza kumanikidzwa kwekamuri yakavharwa. Kutenderera: kutenderera uchienda kurudyi sezvinoonekwa kubva pakubuda. Iyo pombi inofanirwa kumisikidzwa kutsigira mapoinzi, nekuti iyo pombi yekupinda uye yekuburitsa flanges (pombi) haigone kumira paipi uremu.
Mapaipi anofanirwa kucheneswa usati waiswa kudzivirira zvinhu zvekunze kubva mukukuvadza stator ne rotor uye kukonzera kuvhara.
• Dhayamita yepombi inofanira kuenzaniswa nepombi yepombi zvakanyanya. Diki diki inlet dhayamita inokonzeresa kukwana kupihwa pombi, izvo zvinokanganisa kuburitsa kwepombi uye kuburitsa kumanikidza. Muzviitiko zvakakomba, zvinotungamira mukuzungunuka kwepombi uye kukuvara kwekutanga kweiyo stator. Diki diki yekubuditsa pombi madimita zvinoguma nekurasikirwa kwekubuda kwekumanikidza.
• Kune shaft seals ine michina zvisimbiso, wedzera mvura nyowani, mafuta ekuzora, kana chimwe chinotonhorera.
Kune yakasarudzika-yakavharwa shaft seals, kana iyo svikiro iri kuunzwa iri viscous, nyore yakasimbiswa uye yakagadziriswa svikiro, mechiniki chisimbiso chinofanira kucheneswa mushure mekuti pombi yamira kushanda kuti ive nechokwadi cheyakajairika mashandiro echimakanika chisimbiso. Nhengo imwe neimwe yebhokisi rechisimbiso ine inch pombi tambo yekushongedza, uye yekubuditsa inoputira yakakodzera inosanganisirwa. Mutsetse wekupinda wekutenderera fluid wakabatana zvakananga nesimbiso bhokisi. Padivi rayo rekuburitsa, kuburitsa kwakakwenenzverwa (izvo zvakakosha kuti uchengetedze kumwe kumanikidza mubhokisi rekusungirirwa) rinobva rakabatana netambo yekubuda. Paunenge uchimenya muchina, iyo inoyerera fluid inofanira kutanga kutanga, wobva wabatidza pombi; painomira, pombi inofanira kutanga yamiswa, wozodzima iyo inoyerera mvura.
