Pampu yamakina imatchedwanso kuti pampu ya pre-stage, ndipo ndi imodzi mwa mapampu otsika a vacuum omwe amagwiritsidwa ntchito kwambiri, omwe amagwiritsa ntchito mafuta kuti asunge mphamvu yotseka ndipo amadalira njira zamakina kuti asinthe nthawi zonse voliyumu ya chokokera mu pampu, kuti voliyumu ya mpweya womwe uli mu chidebe chopopedwa ikule mosalekeza kuti ipeze vacuum. Pali mitundu yambiri ya mapampu amakina, omwe amagwiritsidwa ntchito kwambiri ndi mtundu wa slide valve, mtundu wa piston reciprocating, mtundu wa vane wokhazikika ndi mtundu wa vane wozungulira.
Zigawo za mapampu amakina
Pampu yamakina nthawi zambiri imagwiritsidwa ntchito kupopera mpweya wouma, koma singathe kupopera mpweya wambiri, mpweya wophulika komanso wowononga, mapampu amakina nthawi zambiri amagwiritsidwa ntchito kupopera mpweya wokhazikika, koma palibe chomwe chingathandize pamadzi ndi gasi, kotero singathe kupopera madzi ndi gasi. Zigawo zomwe zimagwira ntchito yayikulu mu pampu ya rotary vane ndi stator, rotor, shrapnel, ndi zina zotero. Rotor ili mkati mwa stator koma ili ndi mzere wosiyana ndi stator, monga mabwalo awiri amkati, malo ozungulira ali ndi zidutswa ziwiri za shrapnel, pakati pa zidutswa ziwiri za shrapnel pali kasupe wowonetsetsa kuti shrapnel yalumikizidwa bwino ndi khoma lamkati la stator.
Mfundo yogwirira ntchito ya makina opangira makina
Zidutswa zake ziwiri zimagwira ntchito ziwiri motsatizana, mbali imodzi, kuyamwa mpweya kuchokera mu cholowera, ndipo mbali inayo, kukanikiza mpweya womwe walowa kale ndikutulutsa mpweya kuchokera mu pampu. Pozungulira nthawi iliyonse yozungulira, pampu imamaliza kuyamwa kawiri ndi kutsika kawiri.
Pamene pampu ikuzungulira mozungulira nthawi zonse, pampu yozungulira imatulutsa mpweya kudzera mu cholowera ndikuutulutsa kuchokera ku doko lotulutsa mpweya kuti ikwaniritse cholinga chopopera chidebecho. Pofuna kukonza vacuum yomaliza ya pampu, stator ya pampu idzamizidwa mu mafuta kotero kuti mipata ndi malo owopsa pamalo aliwonse nthawi zambiri zimakhala ndi mafuta okwanira kudzaza mipatayo, kotero mafutawo amagwira ntchito yopaka mafuta mbali imodzi, ndipo mbali inayo, amagwira ntchito yotseka ndi kutseka mipata ndi malo owopsa kuti mamolekyu a mpweya asabwerere m'mbuyo kudzera m'njira zosiyanasiyana kupita kumaloko ndi mphamvu yochepa.
Mphamvu ya kutsika kwa mpweya pampu yamakina imagwirizananso ndi liwiro la injini ndi kulimba kwa lamba, pamene lamba wa injini ndi womasuka, liwiro la injini limakhala lochepa kwambiri, mphamvu ya kutsika kwa mpweya pampu yamakina idzakhala yoipa kwambiri, kotero tiyenera kusamalira nthawi zambiri, kuyang'ana malo, mphamvu ya kutseka mafuta pampu yamakina imafunikanso kuyang'ana nthawi zambiri, mafuta ochepa kwambiri, sangathe kufika pa mphamvu ya kutseka, pampu idzatuluka, mafuta ambiri, dzenje loyamwa latsekedwa, silingathe kuyamwa mpweya ndi utsi, nthawi zambiri, mu mafuta mulingo wa 0.5 cm pansi pa mzere.
Pampu ya mizu yokhala ndi pampu yamakina ngati pampu yakutsogolo
Pampu ya mizu: Ndi pampu ya makina yokhala ndi ma rotor awiri kapena ma lobe ambiri omwe amazungulira mofulumira kwambiri. Popeza mfundo yake yogwirira ntchito ndi yofanana ndi ya Roots blower, imathanso kutchedwa Roots vacuum pump, yomwe ili ndi liwiro lalikulu lopompa pamlingo wa 100-1 Pa. Imakwaniritsa zofooka za mphamvu yokwanira ya pampu ya makina pamlingo wa kuthamanga uku. Pampu iyi singayambe kugwira ntchito kuchokera mumlengalenga, ndipo singatulutse mpweya mwachindunji, ntchito yake ndikungowonjezera kusiyana kwa kuthamanga pakati pa cholowera ndi chotulutsira utsi, zina zonse zimafunika kuti pampu ya makina imalize, chifukwa chake, iyenera kukhala ndi pampu ya makina ngati pampu yoyambira.
Kusamala ndi kusamalira mapampu amakina
Mukamagwiritsa ntchito mapampu amakina, nkhani zotsatirazi ziyenera kukumbukiridwa.
1, Pampu yamakina iyenera kuyikidwa pamalo oyera komanso ouma.
2, Pampu iyenera kukhala yoyera komanso youma, mafuta omwe ali mu pampu ali ndi mphamvu yotseka komanso yopaka mafuta, kotero iyenera kuwonjezeredwa malinga ndi kuchuluka komwe kwatchulidwa.
3, Kuti musinthe mafuta a pampu nthawi zonse, mukasintha mafuta otayira kale muyenera kutsuka kaye, nthawi yake ndi miyezi itatu mpaka isanu ndi umodzi kuti musinthe kamodzi.
4, Tsatirani malangizo kuti mulumikize waya.
5, Pampu yamakina iyenera kutseka valavu yolowera mpweya isanayime kugwira ntchito, kenako imazima ndikutsegula valavu ya mpweya, mpweya kudzera mu cholowera mpweya kulowa mu pampu.
6, Pampu ikagwira ntchito, kutentha kwa mafuta sikungapitirire 75℃, apo ayi kudzakhala kochepa kwambiri chifukwa cha kukhuthala kwa mafuta ndipo kungayambitse kutseka kosakwanira.
7, Yang'anani kulimba kwa lamba la pampu yamakina, liwiro la mota, liwiro la mota ya Roots pump, ndi momwe mphete yotsekera imatsekerera nthawi ndi nthawi.
–Nkhaniyi yafalitsidwa ndi Guangdong Zhenhua Technology, kampani yopanga zida zophikira vacuum.
