Isimiso sokusebenza kanye nezinhlobo zokuvalwa kweminyango
Isimiso sokusebenza somnyango siseduze yilapho umnyango uvulwa, umzimba womnyango ushayela induku yokuxhuma ukuze uhambe, okwenza igiya lokudlulisela lijikeleze, futhi lishayela i-rack plunger ukuya kwesokudla.Ngesikhathi sokunyakaza okulungile kwe-plunger, intwasahlobo iyacindezelwa, futhi amafutha we-hydraulic ekamelweni elifanele nawo acindezelwe.Ibhola le-valve yendlela eyodwa ohlangothini lwesobunxele lwe-plunger livuleka ngaphansi kwesenzo sokucindezela kwamafutha, futhi uwoyela we-hydraulic ku-cavity kwesokudla ugeleza ungene emgodini wesobunxele nge-valve yendlela eyodwa.Lapho inqubo yokuvula umnyango isiqediwe, njengoba intwasahlobo icindezelwa phakathi nenqubo yokuvula, kukhishwa amandla anamandla anqwabelene aqoqiwe, futhi i-plunger iphushelwe kwesokunxele ukuze ishayele igiya lokudlulisela nomnyango eduze kwenduku yokuxhuma ukuze ijikelezise, ukuze umnyango uvaliwe.
Ngesikhathi senqubo yokukhishwa kwentwasahlobo, ngenxa yokucindezelwa kwamafutha asebenza ngogesi egumbini elingakwesokunxele lomnyango eduze, i-valve yendlela eyodwa ivaliwe, futhi uwoyela we-hydraulic ungageleza kuphela ngegebe phakathi kwe-casing ne-plunger, futhi dlula imbobo encane ku-plunger kanye ne-2 Iphaseji lokugeleza elifakwe i-throttle spool libuyela ekamelweni elingakwesokudla.Ngakho-ke, uwoyela we-hydraulic uhlanganisa ukumelana nokukhululwa kwentwasahlobo, okungukuthi, umphumela wokuphazamisa ufinyelelwa nge-throttling, futhi isivinini sokuvala umnyango silawulwa.I-valve ye-throttle emzimbeni we-valve ingashintshwa ukuze ilawule isivinini sokuvala esiguquguqukayo sezigaba ezahlukene ze-stroke.Nakuba ukwakheka nobukhulu bezivalo zeminyango ezikhiqizwa abakhiqizi abahlukene zihlukile, isimiso siyafana.
Izinhlobo zokuvalwa kweminyango zingahlukaniswa zibe: izivalo ezifakwe phezulu nezakhelwe ngaphakathi, izivalo zomnyango ophakathi ezakhelwe ngaphakathi, izivalo ezingaphansi komnyango (iziphethu zaphansi), izivalo zezicabha eziqondile (amahinge akhelwe kabusha ngokuzenzakalelayo) kanye ezinye izinhlobo zokuvalwa kweminyango.
Indlela yokulungisa umnyango eduze - indlela yokulungisa isivinini somnyango eduze
Eqinisweni, ukulungiswa kwamandla komnyango oseduze okuchazwe ngenhla kuhlobene ngokuqondile nesivinini sokuvala somnyango oseduze.Ngokuvamile, uma amandla okuvala omnyango oseduze kakhulu, isivinini sokuvala sizoshesha;uma amandla okuvala omnyango oseduze amancane, isivinini sokuvala sizohamba kancane.Ngakho-ke, ukulawulwa kwesivinini somnyango oseduze kufana nokulawulwa kwamandla.Kodwa-ke, ezinye izivalo zeminyango zinezikulufu ezilawula isivinini ngokuqondile, ngakho-ke zidinga ukulungiswa ngokuvumelana namandla nesivinini.Esimeni lapho umnyango oseduze ulungiselwe amandla afanele, uma ufuna ukulungisa isivinini somnyango eduze, ungathola kuqala isikulufu esilungisa isivinini, bese ubona inkomba yesayizi yokulungiswa kwesivinini sokuvala umnyango. i-valve.Uma kukhona abantu asebekhulile noma izingane ezidinga ukunciphisa isivinini sokuvala, vula isikulufu ohlangothini olunciphisa isivinini;uma isivinini sokuvala sihamba kancane futhi umnyango awukwazi ukuvalwa ngesikhathi, vula isikulufu ohlangothini olusheshisa isivinini sokuvala..Kodwa-ke, abantu abanolwazi oluncane ekuhlobiseni bangazama izikhathi eziningana lapho belungisa isivinini somnyango eduze, futhi ekugcineni banqume isivinini somnyango ophansi eduze.
