Pansi pake mpheteyo sikhala bwino, kulongedzako kumatuluka kwambiri ndipo kumawononga shaft yozungulira ya zida. Komabe, izi sizovuta malinga ngati zayikidwa molondola, njira zabwino zosamalira zimatsatiridwa ndipo ntchitoyo ndi yolondola. Atanyamula ndi abwino kwa ambiri ndondomeko ntchito. Nkhaniyi ithandiza ogwiritsa ntchito kukhazikitsa, kugwiritsa ntchito ndikusunga kulongedza ngati katswiri.

Kuyika Molondola

Akachotsa mphete yolongedza yomwe yatopetsa moyo wake ndikuyang'ana bokosi loyikapo, katswiriyo amadula ndikuyika mphete yatsopano. Kuti muchite izi, kukula kwa shaft yozungulira ya zida - mpope - iyenera kuyeza poyamba.

Kuti atsimikizire kukula kolondola kwa kulongedza, munthu amene akudula paketiyo ayenera kugwiritsa ntchito mandrel omwe ali ofanana ndi shaft yozungulira ya zida. Mandrel amatha kupangidwa mosavuta kuchokera kuzinthu zomwe zilipo pamalopo, monga manja akale, mapaipi, ndodo zachitsulo kapena ndodo zamatabwa. Angagwiritse ntchito tepi kuti apange mandrel kukula koyenera. Pamene mandrel akhazikitsidwa, ndi nthawi yoti muyambe kudula. Tsatirani izi:

1. Mangirirani kulongedza mwamphamvu mozungulira mandrel.

2. Pogwiritsa ntchito cholumikizira choyamba ngati chiwongolero, dulani zolozerazo pakona ya 45°. Mphete yonyamulira iyenera kudulidwa kuti malekezero agwirizane mwamphamvu pamene mphete yonyamulirayo ikulungidwa mozungulira mandrel.

Ndi mphete zonyamulira zokonzedwa, akatswiri atha kuyamba kukhazikitsa. Nthawi zambiri, mapampu akuya oyimirira bwino amafunikira mphete zisanu ndi mphete imodzi yosindikizira. Kukhalapo koyenera kwa mphete iliyonse ya kulongedza ndikofunikira kuti pakhale ntchito yodalirika. Kuti izi zitheke, nthawi yochulukirapo imagwiritsidwa ntchito pakukhazikitsa. Komabe, zopindulitsa zake zikuphatikiza kutayikira pang'ono, moyo wautali wautumiki, komanso kusamalidwa kochepa.

Pamene mphete iliyonse yonyamulira imayikidwa, zida zazitali komanso zazifupi ndipo pamapeto pake mphete yosindikizira imagwiritsidwa ntchito kukhazikitsa mphete iliyonse yonyamula. Yendetsani zolumikizira za mphete iliyonse yonyamula ndi 90 °, kuyambira 12 koloko, kenako 3 koloko, 6 koloko, ndi 9 koloko.

Komanso, onetsetsani kuti mphete yosindikizira ili m'malo kuti madzi otsekemera alowe m'bokosi losungiramo zinthu. Izi zimachitika polowetsa chinthu chaching'ono mu doko lothamangitsira ndikumvera mphete yosindikizira. Mukayika mphete yachisanu ndi yomaliza yonyamula, wotsatira wa gland yekha ndi amene adzagwiritsidwe. Woyikirayo ayenera kumangitsa wotsatira gland pogwiritsa ntchito ma 25 mpaka 30 mapazi-mapaundi a torque. Kenako masulani chithokomiro chonsecho ndikulola kulongedza kumasuka kwa masekondi 30 mpaka 45.

Pambuyo pa nthawiyi, gwiraninso chala cha gland. Yambani unit ndikusintha ngati kuli kofunikira. Kutayikira kuyenera kukhala madontho 10 mpaka 12 pa mphindi imodzi pa mainchesi a m'mimba mwake.

Kusintha kwa Shaft

Ngati shaft a pampu yakuya ya turbine yakuya bwino Imapotoka, imapangitsa kuti compression isunthike ndipo mwina iwononge. Kupindika kwa shaft ndiko kupindika pang'ono kwa shaft ya mpope pamene liwiro la choyikapo madzi likukankhira madziwo silofanana m'malo onse mozungulira choponderacho.

Kupatuka kwa shaft kumatha kuchitika chifukwa cha ma rotor osakhazikika, kusanja bwino kwa shaft, ndi ntchito yapampu kutali ndi komwe kuli bwino. Opaleshoniyi ipangitsa kuti kunyamula katundu kusakhale nthawi yayitali ndikupangitsa kuti zikhale zovuta kuwongolera ndikugwiritsa ntchito kutayikira kwamadzimadzi. Kuwonjezera shaft stabilizing bushing kungathandize kuchepetsa kapena kuthetsa vutoli.

Kusintha kwa Njira ndi Kudalirika kwa Bokosi Loyika

Kusintha kulikonse mu ndondomeko madzimadzi kapena otaya mlingo zimakhudza stuffing bokosi ndi psinjika kulongedza katundu mkati mwake. Bokosi loyikamo lamadzimadzi liyenera kukhazikitsidwa ndikuyendetsedwa moyenera kuonetsetsa kuti kulongedzako kumakhalabe koyera komanso koziziritsa pogwira ntchito. Kudziwa kupanikizika kwa bokosi lopangira zinthu ndi mizere ya zida ndi sitepe yoyamba. Kaya mukugwiritsa ntchito madzimadzi osungunula kapena kupopera madzimadzi (ngati ali oyera komanso opanda tinthu ting'onoting'ono), kupanikizika komwe kumalowa mu bokosi lazinthu ndizofunikira kwambiri kuti mugwire ntchito bwino ndi kunyamula moyo. Mwachitsanzo, ngati wosuta amaletsa kupopera otaya nthawi iliyonse ndi valavu kuda, ndi stuffing bokosi kuthamanga adzakhudzidwa ndi kupopera madzi munali particles adzalowa stuffing bokosi ndi kulongedza katundu. Kuthamanga kwa pompopompo kuyenera kukhala kokwanira kuti athe kubwezera zovuta zilizonse zomwe zingachitike panthawi yogwiritsira ntchito pampu yakuya yoyimirira ya turbine.

Kupukuta sikutanthauza madzi otuluka kuchokera mbali imodzi ya bokosi loyikapo ndi kunja kwa mbali inayo. Imaziziritsa ndikupaka mafuta, motero imakulitsa moyo wake ndikuchepetsa kuvala kwa shaft. Imasunganso tinthu tating'onoting'ono tomwe timatulutsa.

Kusamalira Bwino Kwambiri

Pofuna kusunga kudalirika kwa bokosi loyikapo zinthu, madzi osungunula amayenera kuyendetsedwa kuti zonyamulazo zikhale zoyera, zoziziritsa kukhosi komanso zopaka mafuta.

Kuonjezera apo, mphamvu yomwe imagwiritsidwa ntchito ndi wotsatira gland pa kulongedza iyenera kusinthidwa ngati pakufunika. Izi zikutanthauza kuti ngati kutayikira kwa bokosi lopangira zinthu kuli kwakukulu kuposa madontho 10 mpaka 12 pamphindi pa inchi imodzi ya m'mimba mwake, gland iyenera kusinthidwa. Katswiri akuyenera kusintha pang'onopang'ono mpaka kuchuluka kwa kutayikira koyenera kukwaniritsidwa kuti atsimikizire kuti kulongedza kwake sikuli kolimba kwambiri. Pamene chithokomiro sichingathenso kusinthidwa, zikutanthauza kuti moyo wolongedza wa mpope wakuya woyimirira watha ndipo mphete yatsopano yonyamula iyenera kuikidwa.
