1. Kugadziriswa kwe torque yekumisa mashandiro
Magetsi egedhi mavharuvhu anoiswa munzvimbo dzakasiyana nekuda kwemusiyano wekumanikidza kumagumo ese evhavha yegedhi kana mutsauko wekumanikidza kwemhepo (gedhi vharafu rakavharwa), iyo torque yekumisa nzira inofanirwa kugadziridzwa zvakakodzera. Mukushandiswa kwevharuvhu yegedhi remagetsi pamativi ese azimuthal kudzvanywa kana mhepo yakaderera nzvimbo, torque inodzika nzira inofanirwa kugadziridzwa kune yakaderera torque, HZ yakatevedzana zvigadzirwa (sezvinoratidzwa muFigure 1), Z zvakatevedzana zvigadzirwa (sezvinoratidzwa mumufananidzo. 2) kana ZB zvakatevedzana zvigadzirwa (sezvinoratidzwa muFigure 3) yemagetsi inodzora vharafu, inongoda kugadzirisa torque inodzikamisa meshini yekugadzirisa ndiro uye chinhambwe pakati peinofamba ndiro kuti iwane (yakadzama gadziriso). Iyo mutongi ndiro yakanyorwa nemutongi, uye iyo yakawanda kukosha kwechiyero, iyo yakakura kukosha kwetorque. Magetsi anodzora vharafu gedhi revhavha yakavharwa kana mutsauko wekumanikidza pakati pemigumo miviri kana kudzvanywa kwemhepo zvakanyanya, iyo yakagadziriswa torque kukosha inoda kuve yakawanda, pane zvinopesana, idiki. Iwo pamusoro akati wandei akateedzana echigadzirwa kugadzirisa nzira yakafanana. Paunenge uchigadzirisa ZD yakatevedzana yemagetsi ekudzora vharafu (sezvinoratidzwa muMufananidzo 4), bvisa chivharo chepadivi chegoko, gadzirisa torque inodzika meshini, sunungura screwing screw mu screw yekugadzirisa, sunungura screw yekugadzirisa, sunungura bhatani rekumanikidza torque chitubu, uye uise muchikamu chakasununguka, uye simbisa chigadziko chekugadzirisa mukugadzirisa screw, gadzirisa kugadzirisa screw. Ziva kuti pamusoro peiyo screwing screw inofanira kuwira mukati me shaft groove body. Kana kumusoro kukasanongedza kune shaft groove chaizvo, kungoita diki diki yekutenderera kwekona yekugadzirisa munzira ye torsion spring inodiwa kuti iite inongedza kune shaft groove fixing screw. Isa pachifukidzo chedivi uye gadzirisa valve yegedhi. Kana iyo torque inoganhura nzira yekusimbisa muviri, iyo torsion chitubu chakanyanya kusununguka uye chakasimba kune chinzvimbo. Izvi zvinogona kuita kuti torque inodzikamisa meshini ishande pasi peyakadzikira torque, kuve nechokwadi chekuti gedhi remagetsi vharafu nekuda kwekufamba kurongeka kwekudzora masisitimu kutadza, kana zvimwe zvikonzero zvekunyanyisa torque, torque inomisa nzira inovimbika kumira, uye kudzima mota inochinja magetsi, chengetedza. vharafu haizoparadzwi. Ivhavha yegedhi yegedhi inoshandiswa mune dzimwe nzvimbo zvakare haidi kugadziridzwa kuti ivhare zvakanyanya, inogadziriswa kumhando yemanyorero yekuvhara uyezve yakasununguka kumashure maviri mhete (kana mhete) yakakodzera, (kana hapana mvura kana gasi yakakodzera) .
Kana vheji yegedhi yegedhi yaiswa munzvimbo iyo iyo mvura inoburitsa kudzvanywa musiyano (kana mhepo yekumanikidza) yakawanda, torque yekumisa nzira inofanirwa kugadziridzwa kune yakakodzera kuvhura uye kudzima torque. Semuenzaniso, mvura yekubuda kwegedhi valve yakaiswa muimba yepombi, mushure mokunge pombi ye centrifugal yatanga, mvura yekubuda kwemvura inenge yakakura kana gedhi regedhi risina kuvhurwa. Panguva ino, iyo yakawanda yemvura yekubuda gedhi mavharuvhu, iyo yakawanda torque inoshandiswa kuvhura gedhi vharafu. Kunyanya kana pasina kumanikidzwa mupombi, iyo unilateral pressure iyo gedhi valve inogona kutakura yakakura kwazvo. Panguva ino, screw torsion chitubu chinogadziridzwa kune yakajairwa kuvhura uye kuvhara kwevhavha yegedhi, uye torque yekumisa mashandiro haisi munzvimbo. Ivhavha yegedhi yegedhi inoshandiswa muimba yepombi inofanira kugadziriswa kunzvimbo yakazaruka yakavharwa zvakakwana, kana zvisina kudaro zviri nyore kukuvadza gedhi revhavha yepamusoro zvichiita kuti mvura isvike. Nemhaka yokuti vheji yegedhi yegedhi yakaiswa panzvimbo ino iri pedyo nepakati pepombi yemvura ye centrifugal, chiyero chekuyerera kwemvura chakakwirira uye chisina kugadzikana. Panguva ino, kana gedhi vharafu isina kuvhurwa zvizere, mamwe mavharuvhu egedhi anozununguka kubva kune rumwe rutivi kuenda kune rumwe rutivi nekuda kwekukanganisa kwekuyerera kwemvura, zvekuti chiso chevharuvhu yegedhi chakakuvadzwa, zvichikonzera concave groove mvura seepage inokuvadza hupenyu hwebasa. yevhavha yegedhi. Kuwedzera kuedza kudzivisa kushandisa magetsi gedhi vharafu kugadzirisa vharafu, zvikasadaro zviri nyore kuparadza gedhi vharafu pamusoro. Pamusoro pezvo, mumakore achangopfuura, tekinoroji yekumhanyisa kumhanyisa yekudzora tekinoroji iri kukurumidza kukura, pombi inoyerera inogadziriswa inofanirwa kushandisa frequency kutendeuka nekukurumidza regulation tekinoroji, kuitira kuchengetedza simba uye kuderedza kuburitswa kwekuvandudza kushanda kwe centrifugal pombi.
2 Magetsi gedhi vharafu "yakavhurika, vhara" chinzvimbo kugadzirisa
Gadzirisa kuvhura uye kuvhara kwemagetsi egedhi mavharuvhu. Maererano nekugadzirisa mitemo yemugadziri wega wega, gedhi regedhi rinofanira kuvharwa nemaoko kune chikamu "chakavharwa" kana chikamu "chakazaruka". Kana izvi zvichida diki caliber gedhi revhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhaivhaye nguva iwande, kana kuti inonetsa. Nzira itsva yekugadzirisa inounzwa pano zvakadzama: kana stem spacing yevhavha yegedhi ichizivikanwa, zvichava nyore kugadzirisa gedhi regedhi valve paunenge uchigadzirisa. Mazuvano, nzvimbo yehunde yevharuvhu yegedhi ine caliber yeDN400-DN600 inogadzirwa muChina inowanzoita 8mm, uye hunde hwevharuvhu yegedhi ine caliber pamusoro peDN600 inowanzoita 10mm. Kana zvichibvira, bvunza mugadziri wevharuvhu yegedhi kuti aone kuti stem spacing. Paunenge uchigadzirisa magetsi ekugadzirisa magetsi, kana iwe uchiziva nzvimbo yevhavha yegedhi mberi, kana iwe uchiziva kuti gedhi regedhi riri munzvimbo yose yakavharwa, unofanira kugadzirisa chikamu "chakavharwa zvakakwana" kutanga. Kutanga, nemaoko tenderedza vharafu yegedhi kunzvimbo yekutanga, senge mbiri kana imwe kutenderera kwehunde. Wobva wadyisa musimba rekuchinja uye tinya bhatani re "On". Tarisa kutendeuka. Kana kutsauka kwechidzitiro chevharuvhu kuchienderana nekushandurwa kwechitsigiro chevharuvhu kana vharafu ichivhurwa nemaoko zvichienderana nebhatani rekuvhura, zvinoratidza kuti mutsara usina kwawakarerekera wemota uri munzira imwechete neyemagetsi emagetsi controller wevhavha. . Panguva ino, nzira yekufambisa yekufambisa yevhavha yegedhi inofanira kugadziriswa kune chikamu chakavharwa zvakakwana. Panguva ino, paunovhura gedhi revhavha, verenga nhamba yekutendeuka kwestem kutenderera kwevhavha yegedhi kuti uzive kana kune "yakavhurika" nzvimbo. Kana iri vharuvhu yegedhi remagetsi reDN500, mazino emazino ari 8mm, dzinde revharuvhu rinotenderera kamwe chete kuvhura 8mm, uye gedhi rakazaruka rakazara vharafu rinoda kuita 500mm yekukwira kumusoro, saka hunde yevharuvhu yakazaruka inoda kutenderera. 500/8 = 62.5 kutendeuka. Panguva ino, dzvanya kiyi yakavhurika yevharuvhu uye uverenge 63 kutendeuka kwegedhi vharafu kune "yakavhurika" chinzvimbo, gadzirisa yemagetsi inodzora vharuvhu yekufamba control board, kuitira kuti toggle switch chinzvimbo munzvimbo "yakavhurika" inogona kuva. Kubva ipapo zvichienda mberi, vheji yegedhi yegedhi inogona kuvharwa, kuvhurwa uye kuongororwa zvakare, uye kugadzirisa kunopedzwa. Kana vheji yegedhi yegedhi iri munzvimbo yekuvhura isati yagadziriswa, inofanira kugadziriswa kuti itange nzvimbo, iyo nzira maererano nepamusoro.
