I-Slurry Couplings indlela yokuthola isikhungo

Slurry Couplings kanjani ukuthola isikhungo?

I-Slurry Couplings efuna ukuthola isikhungo isekelwe esikhungweni se-coupling shaft. Ivamise ukubizwa ngokuqondisa kwesondo . Ngoba iphampu iwumshini oshayelwa yinjini noma esinye isinyakazi esiyinhloko , ngakho-ke imfuneko encane ukuthi ama-shaft amabili ahlotshaniswa ne-eksisi aqondane, ukuze isebenze kahle, kungabikho ukudlidliza. Ngabe ama-eksisi amabili angaqondana kanjani ne-eksisi yawo?

Indawo elungile (a) ayikho ngaphambi kwe-eksisi yamakhodi , bese kuba nomlomo wokumpompa ohambisanayo , inani elingu-b; motor shaft , kanye nenani eliphansi, eliphansi lika-Δh, i-eksisi ukuze kwenziwe ama-eksisi amabili aqondane, ekulungiseni okulandelayo:

1 Okokuqala susa ukuphakama kokuhlanganisa. Kulokhu ishafu yemoto kufanele igandaywe u-Δh, ngemva kwezimo zokugandaya njengoba (b) ibonisa. Bese kuthi ingaphambili nangemuva eline-A bearing B kufanele futhi kwengezwe ngaphansi komcamelo wesihlalo Δh.

2 . Susa ukuhlanganisa umlomo . Lokhu kungaba ukwenyuka kogqinsi oluhlukene oluveza i-shim AB ngokulandelana . I-B plus pad holder ukuze ibe mkhulu kuno-A (emva kokwenyuka koshintsho ukuhlangana kufanele kuqinisekise ukuthi i-gasket ekuqondeni kobude ayenzeki).

Ilungiswa kanjani? Dlula izibalo. Naka lokho okubalulekile ukugcwaliswa komhlangano ? Isigcwalisi somhlangano kufanele siqaphele lezi zindaba ezilandelayo:

1 Ukupakisha okucacisiwe kwesokudla, nokusebenza koketshezi olusebenzayo ukuze kuhambisane kahle ukuze kuhlangatshezwane nezidingo zikasayizi. Uma ukupakisha kuncane kakhulu, nakuba indlala yokupakisha isikulufa iqine kakhulu,umkhiqizi wepompo ye-slurrykodwa umphumela wophawu ngokuvamile ongasebenzi.

2 Amajoyinti okugcwalisa kufanele anyakaziswe 90-180 Qaphela ukuthi ngalinye kufanele libe yindilinga egcwele ngemva kokupakishwa kwendilinga efakwe ebhokisini lokugxusha , hhayi ukushoda.

3 Uma uhlangabezana nebhokisi lokugxusha liyi-oval , ungakwazi ukwengeza olunye ucingo olukhudlwana lwesigcwalisi eseceleni kukhonjiswe kuMfanekiso 4-20 i-atrium. Uma kungenjalo , izimo ezilandelayo zingenzeka . Okusho ukuthi uhlangothi oluncane lunokucindezela okuqinile kakhulu, ngenkathi kuseyigebe elikhulu, bese kulula ukuvuza kusuka ohlangothini olukhudlwana noma umusi kusuka ohlangothini oluncane.

4 Uma usebenzisa okokugcwalisa, indandatho yokugcwalisa ukuze iqondaniswe nendawo yokuphuma. Ezinye izindandatho zokupakisha zephampu , ngokuvamile ezilula, khona-ke ungakwazi ukufaka indandatho yokupakisha eyimodyuli ebalulekile, kubonakale kukuhle kakhulu. Indandatho yokupakisha ehlanganisiwe iboniswa ku-Figure 4-22, isigcwalisi somzimba, okuwukuthintana kwamaphuzu amane kuphela nebhokisi lokupakisha langaphandle, okungekho lula ukujamza, ngokungqubuzana okuncane. 2 iyindandatho yegiya , izacile ( 3 a 4 mm ) , kulula ukuyikhipha .

5 Ngemva kokuba isigcwalisi siqinile, indlala izungezwe igebe ukuze lilingane. Enye i-Slurry, igebe phakathi kwe-b ne-shaft packing gland lincane, kungcono kakhulu ukusebenzisa i-feeler gauge ukuze ulinganise lokho okugwema ukungqubuzana kwe-gland kanye ne-shaft.
