Makasitomala ambiri sadziwa kusankha wononga mpweya kompresa. Lero, OPPAIR ilankhula nanu za kusankha kwa screw air compressor. Tikukhulupirira kuti nkhaniyi ingakuthandizeni.
Masitepe atatu kusankha screw air compressor
1. Dziwani kuchuluka kwa ntchito
Posankha arotary screw air compressor, choyamba muyenera kudziwa kuthamanga kwa ntchito komwe kumafunikira kumapeto kwa mpweya, onjezerani malire a 1-2 bar, ndiyeno sankhani kuthamanga kwa mpweya wa compressor. Zoonadi, kukula kwa mapaipi awiri ndi chiwerengero cha malo otembenuka ndizinthu zomwe zimakhudza kutaya kwa kuthamanga. Kukula kwake kwa mapaipi ndi malo okhotakhota ochepa, kumachepetsa kuchepa kwa mphamvu; m'malo mwake, m'pamenenso kuthamanga kutaya.
Choncho, pamene mtunda wapakati pa ma screw compressor a mpweya ndi payipi yomaliza ya gasi uli patali, m'mimba mwake wa payipi yayikulu iyenera kukulitsidwa moyenera. Ngati chikhalidwe cha chilengedwe chikukwaniritsa zofunikira za kuyika kwa compressor ya mpweya ndi momwe zimagwirira ntchito zimalola, zikhoza kuikidwa pafupi ndi mapeto a gasi.
2. Dziwani kuchuluka kwa ma volumetric oyendera
(1) Posankha ascrew air compressormuyenera kumvetsetsa kaye kuchuluka kwa ma voliyumu a zida zonse zogwiritsa ntchito gasi ndikuchulukitsa kuchuluka kwakuyenda ndi 1.2;
(2) Funsani wopereka zida zogwiritsira ntchito gasi za kuchuluka kwa kuchuluka kwa voliyumu yamagetsi ogwiritsira ntchito gasi kuti asankhe makina opondereza mpweya;
(3) Mukakonza siteshoni ya compressor ya air screw, mutha kutchula zomwe zidayambira ndikuziphatikiza ndi momwe gasi amagwiritsidwira ntchito kuti musankhe kompresa ya mpweya.
3. Dziwani mphamvu zamagetsi
Pamene liwiro likusintha pamene mphamvu imakhala yosasinthika, kuthamanga kwa volumetric ndi kuthamanga kwa ntchito kudzasinthanso moyenera. Pamene liwiro likuchepa, kutulutsako kudzachepanso moyenerera, ndi zina zotero.
Mphamvu ya kusankha kompresa ya mpweya ndikukwaniritsa kuthamanga kwa ntchito ndi kuyenda kwa volumetric, ndipo mphamvu yamagetsi imatha kukumana ndi mphamvu yagalimoto yofananira.
Mfundo zinayi zofunika kuzidziwa posankha screw air compressor
1. Ganizirani za kuthamanga kwa mpweya ndi mphamvu yotulutsa mpweya
Malinga ndi muyezo wadziko lonse, mphamvu yotulutsa mpweya wa 0.7MPa (7 atmospheres), ndipo muyezo wakale ndi 0.8MPa (8 atmospheres). Chifukwa kamangidwe ntchito kuthamanga kwa pneumatic zida ndi mphepo makina mphamvu ndi 0.4Mpa, kuthamanga ntchito yascrew air compressorakhoza kukwaniritsa zofunikira. Ngati kompresa wogwiritsidwa ntchito ndi wamkulu kuposa 0.8MPa, nthawi zambiri amapangidwa mwapadera, ndipo kukakamiza kokakamiza sikungatengedwe kuti apewe ngozi.
Kukula kwa voliyumu yotulutsa ndi chimodzi mwazinthu zazikulu za compressor ya mpweya. Mpweya wa mpweya wa kompresa uyenera kufanana ndi kuchuluka kwa mpweya womwe umafunikira pawekha, ndikusiya malire a 10%. Ngati kugwiritsira ntchito gasi kuli kwakukulu ndipo voliyumu yotulutsa mpweya wa compressor ndi yaying'ono, chida cha pneumatic chikatsegulidwa, kuthamanga kwa mpweya wa compressor kudzachepetsedwa kwambiri, ndipo chida cha pneumatic sichikhoza kuyendetsedwa. Kumene, mwachimbulimbuli kuthamangitsa lalikulu utsi voliyumu ndi kulakwanso, chifukwa chachikulu utsi voliyumu, yaikulu galimoto okonzeka ndi kompresa, amene si mtengo chabe, komanso kuwononga ndalama kugula, komanso kuwononga mphamvu magetsi pamene ntchito.
Kuphatikiza apo, posankha voliyumu yotulutsa mpweya, kugwiritsa ntchito pachimake, kugwiritsiridwa ntchito kwanthawi zonse, komanso kugwiritsa ntchito mbewa ziyeneranso kuganiziridwa. Njira yanthawi zonse ndikulumikiza ma compressor a mpweya ndi kusamutsidwa kwakung'ono molumikizana kuti mupeze kusamutsidwa kwakukulu. Pamene kugwiritsa ntchito gasi kumawonjezeka, amayatsidwa mmodzimmodzi. Izi sizili zabwino kokha kwa gridi yamagetsi, komanso zimapulumutsa mphamvu (yambani zambiri zomwe mukufunikira), ndipo zimakhala ndi makina osungira, kotero kuti mzere wonse sungatseke chifukwa cha kulephera kwa makina amodzi.
2. Ganizirani nthawi ndi mikhalidwe yogwiritsira ntchito gasi
Nthawi ndi malo ogwiritsira ntchito gasi ndizofunikiranso posankha mtundu wa compressor. Ngati malo ogwiritsira ntchito gasi ndi ochepa, mtundu woyimirira uyenera kusankhidwa. Mwachitsanzo, za zombo ndi magalimoto; ngati malo ogwiritsira ntchito gasi asinthidwa pa mtunda wautali (kuposa mamita 500), mtundu wa mafoni uyenera kuganiziridwa; ngati malo ogwiritsira ntchito sangathe kuyendetsedwa, mtundu wa injini ya dizilo uyenera kusankhidwa;
Ngati mulibe madzi apampopi pamalo ogwiritsira ntchito, mtundu wa mpweya wozizira uyenera kusankhidwa. Pankhani ya kuzizira kwa mpweya ndi kuzizira kwa madzi, ogwiritsa ntchito nthawi zambiri amakhala ndi chinyengo chakuti madzi ozizira bwino ndi abwino komanso kuti kuzizira kumakhala kokwanira, koma izi siziri choncho. Pakati pa ma compressor ang'onoang'ono, kunyumba ndi kunja, kuzirala kwa mpweya kumakhala kopitilira 90%.
Ponena za kapangidwe kake, kuziziritsa kwa mpweya ndikosavuta ndipo sikufuna madzi akagwiritsidwa ntchito. Kuziziritsa madzi kuli ndi kuipa kwake. Choyamba, iyenera kukhala ndi madzi okwanira komanso ngalande, zomwe zimafuna ndalama zambiri. Chachiwiri, madzi ozizira ozizira amakhala ndi moyo waufupi. Chachitatu, n'zosavuta kuzizira silinda m'nyengo yozizira kumpoto. Chachinayi, madzi ambiri adzawonongeka panthawi yogwira ntchito bwino.
3. Ganizirani za khalidwe la mpweya wothinikizidwa
Nthawi zambiri, mpweya woponderezedwa wopangidwa ndi ma compressor a mpweya umakhala ndi mafuta ena opaka mafuta komanso madzi ena. Nthawi zina, mafuta ndi madzi amaletsedwa. Panthawiyi, musamangoganizira za kusankha kwa compressor, koma muyenera kuwonjezera zipangizo zothandizira ngati kuli kofunikira.
4. Ganizirani za chitetezo cha ntchito
Air Compressor ndi makina omwe amagwira ntchito mopanikizika. Pogwira ntchito, zimaphatikizidwa ndi kukwera kwa kutentha ndi kupanikizika. Chitetezo cha ntchito yake chiyenera kuperekedwa patsogolo. Kuphatikiza pa valavu yotetezera, mpweya wa compressor ulinso ndi chowongolera chowongolera popanga, ndipo inshuwaransi iwiri yotsitsa kutsitsa imayendetsedwa. Ndizosamveka kukhala ndi valavu yotetezera yokha koma palibe chowongolera. Sizidzangokhudza chitetezo cha makina, komanso kuchepetsa kuyendetsa bwino kwachuma (ntchito yaikulu ya wolamulira wopanikizika ndi kutseka valavu yowonongeka ndikupangitsa makinawo kuti aziyenda mopanda pake).
