Mu makina a pneumatic a galimoto kapena thirakitala, kuchuluka kwa chinyezi (condensate) ndi mafuta nthawi zonse zimadziunjikira - zonyansa izi zimachotsedwa kuchokera kwa olandila kudzera mu mavavu a condensate (mavavu).Werengani zonse za ma cranes awa, mitundu yawo ndi mapangidwe ake, komanso kusankha kwawo kolondola ndikusintha m'malo mwake, m'nkhaniyi.
Kodi valavu ya condensate ndi chiyani?
Valve ya condensate (condensate drain valve, valve drainage, valve valve) - gawo la ma brake system yamagalimoto okhala ndi pneumatic drive;Vavu yoyendetsedwa pamanja kapena valavu yopangidwa kuti ikhetse mpweya wa condensate ndikutulutsa magazi kuchokera kwa olandila.
Pakugwira ntchito kwa ma pneumatic system, ma condensate ndi madontho amafuta ochokera ku kompresa amadziunjikira m'zigawo zake - zolandila (ma silinda a mpweya) ndi mapaipi.Chinyezi chimalowa m'dongosolo chifukwa cha kuponderezedwa ndi kutentha ndi kuzizira kwa mpweya, ndipo mafuta amalowa kuchokera ku makina opangira mafuta a compressor Kukhalapo kwa madzi m'dongosolo kumabweretsa kuwonongeka kwakukulu kwa zinthu zake, ndipo m'nyengo yozizira kumatha kusokoneza zachibadwa. kugwira ntchito kwa matepi, ma valve ndi zida zosiyanasiyana.Choncho, olandira amapereka zipangizo utumiki wapadera - mavavu kapena matepi kukhetsa condensate (madzi) ndi mafuta.
Mothandizidwa ndi ma valve a condensate, ntchito zingapo zazikulu zimathetsedwa:
● Kuthamangitsidwa kwa condensate kuchokera ku masilinda a mpweya pakukonzekera tsiku ndi tsiku kapena pakufunika;
● Kuchotsa mafuta amene amaunjikana mwa olandira;
● Kukakamiza kutulutsa mpweya kuchokera kwa olandira kuti achepetse kuthamanga kwa dongosolo (mwachitsanzo, kukonza ndi kukonza), kuyang'ana ntchito ya kompresa ndi zipangizo zina, ndi zina.
Valve ya condensate drainage imatsimikizira kugwira ntchito kwabwino kwa ma brake system oyendetsedwa ndi pneumatic, kotero kuwonongeka kwa gawoli kuyenera kuthetsedwa posachedwa.Koma musanagule ndikuyika crane yatsopano, muyenera kumvetsetsa mitundu yomwe ilipo ya zidazi, kapangidwe kake ndi mawonekedwe ake.
Mitundu ndi kapangidwe ka mavavu a condensate drain
Mitundu iwiri yazida imagwiritsidwa ntchito kukhetsa condensate, yosiyana pamagwiritsidwe ntchito ndi kapangidwe:
● Mavavu;
● Mavavu okhala ndi mitundu yosiyanasiyana ya chinthu chozimitsa.
Mavavu ndi zida zophweka zomwe zitha kukhala pa "Otsekedwa" ndi "Open" malo.Masiku ano, ma valve opanikizika okhala ndi mitundu iwiri ya ma actuators amagwiritsidwa ntchito:
● Pogwiritsa ntchito ndodo yolunjika (ndi ndodo yopendekera);
● Ndi lever rod drive (ndi ndodo yokankha).
Ma valve a condensate amtundu woyamba amakhala ndi mapangidwe osavuta.Maziko a chipangizocho ndi nkhani mu mawonekedwe a kok, ulusi pamwamba pake ndi muyezo turnkey hexagon amaperekedwa.M'kati mwa thupi muli valavu - mbale yozungulira yozungulira yokwera pa ndodo (pusher), wopondereza amadutsa pa dzenje lakutsogolo kwa thupi, ndipo mbale ya valve imakanizidwa kukhoma ndi kasupe wokhotakhota ( mphete yachitsulo kapena mbale imaperekedwa kuti ayime).Bowo lopingasa limabowoleredwa kumapeto kwa tsinde kuti aike mphete kuti agwiritse ntchito ngati gawo la ngalande zakutali za condensate.Thupi la valve nthawi zambiri limapangidwa ndi mkuwa kapena mkuwa, koma lero palinso zinthu zapulasitiki.Tsinde nthawi zambiri ndi chitsulo, zomwe zimatsimikizira mphamvu yapamwamba ya mankhwala.
Mapangidwe a valve ya condensate drain (vavu)
Condensate drainage valve yokhala ndi lever actuator
Mavavu okhala ndi makina opangira ma lever amasiyana kokha pamaso pa kachipangizo kakang'ono kachitsulo komwe kamatsimikizira kuti tsinde likukanikizidwa.Kapangidwe kameneka kamakhala kosavuta pazovuta zazikulu, komanso kumaperekanso kutsegulira ndi kutseka kwa valve.Zida zoyendetsedwa ndi Lever zimagwiritsidwa ntchito nthawi zambiri pamagalimoto olemetsa akunja.
Valve ya condensate drainage imagwira ntchito motere: pansi pa kukakamiza mkati mwa wolandila ndi mphamvu ya masika, valavu imatsekedwa, kuonetsetsa kuti dongosololi likulimba;Kukhetsa mpweya wa condensate kapena kukhetsa magazi, ndikofunikira kusuntha tsinde kumbali (koma osayikanikiza) - valavu imadzuka ndipo mpweya udzatsitsidwa kudzera mu dzenje lomwe limanyamula condensate ndi mafuta.Kuti zitheke kusuntha tsinde, dzenje lakutsogolo kwa valavu limatsukidwa.Kwa machitidwe akutali a condensate ngalande, mphete yachitsulo imayikidwa pa ndodo, yomwe imagwirizanitsidwa ndi chingwe chowongolera - chingwechi chimadutsa mu thupi kapena chimango cha galimoto, mapeto ake achiwiri amagwirizanitsidwa ndi chogwirira mu cab.Pamene chogwirirachi chikanikizidwa (kapena kusuntha), chingwecho chimakoka tsinde la valve, zomwe zimatsimikizira kukhetsa kwa condensate.Dongosolo lotereli limagwiritsidwa ntchito pamabasi ambiri apanyumba ndi magalimoto okhala ndi olandila ambiri.
Ma valve a condensate (kapena, monga nthawi zina amatchedwa, ma valve) ndi zipangizo zovuta kwambiri, masiku ano amagwiritsidwa ntchito kawirikawiri (nthawi zambiri amapezeka pamagalimoto akale apakhomo).Mwadongosolo, ndi mpira kapena valavu ya cone, chinthu chotseka chomwe chimalumikizidwa ndi chogwirira chozungulira.Maziko a crane ndi thupi, lomwe mkati mwake muli mpira kapena chulu chokhala ndi dzenje pamipando yake, ndipo ulusi wa turnkey ndi hexagon zimapangidwa panja (osati pazida zonse).Chinthu chotseka cha valve chimalumikizidwa mwamphamvu ndi ndodo, yomwe imatuluka m'nyumba kudzera mu chisindikizo.Mavavu amapangidwanso nthawi zambiri ndi mkuwa ndi mkuwa, zinthu zotsekera zimatha kukhala chitsulo.Valavu imagwira ntchito motere: pamalo otsekedwa, chinthu chotsekedwa chimazungulira motere kuti dzenje lomwe liri mkati mwake silimatsekedwa ndipo njira ya thupi la crane imatsekedwa;Chogwiriracho chikatembenuzidwa, chinthu chokhomacho chimazunguliranso, ndipo mpweya wokhala ndi condensate ndi mafuta umatuluka kudzera mubowo momwemo.
Mavavu ambiri ndi mavavu ali ndi ulusi wa M22x1.5, chipangizocho chimayikidwa mwa bwana ndi ulusi wamkati wotsekedwa pamunsi kwambiri pa silinda ya mpweya - pamtunda wake wapansi (ndi kusuntha kumodzi mwa malekezero kuti zitheke kukonza - mbali iyi ya wolandirayo imayendetsedwa kunja kwa chimango cha galimoto) kapena pansi pa imodzi mwa makoma a mapeto.Mavavu nthawi zambiri amaikidwa mu abwana pansi pamwamba, ndi mavavu kukhetsa akhoza kukhala pa mapeto makoma - mu nkhani iyi ali ndi bend kutsogolera otaya mpweya ndi condensate vertically pansi.Mavavu ndi ma cranes ali ndi zolandila zambiri kapena zonse zokhala ndi makina opopera agalimoto, thirakitala kapena zida zina.
Nkhani zakusankha ndikusintha valavu ya condensate drain
M'kupita kwa nthawi, mbali ya valavu ndi valavu - kutsekereza chinthu ndi mpando wake, akasupe, etc. - kutha ndi kupunduka, zomwe zimabweretsa kuchucha mpweya kapena kusokoneza ntchito yachibadwa ya valavu.Gawo loterolo lingayambitse kusagwira ntchito bwino kwa makina a pneumatic, choncho liyenera kusinthidwa.
Kusankhidwa kwa valavu yatsopano ya condensate ndikosavuta - zonse (kapena mbali zambiri zomwe zimagwiritsidwa ntchito pamitundu yotchuka yamagalimoto) pamsika masiku ano ndizokhazikika, kotero mutha kutenga pafupifupi chilichonse chagalimoto.Nthawi yomweyo, ndikofunikira kuyika valavu yomweyi paolandila pomwe valavu idayima poyamba, ndi crane pa olandila ndi crane.Kwa magalimoto omwe ali ndi makina akutali a condensate, valve yokhala ndi mphete yachitsulo mu tsinde ikufunika, yomwe imagwirizanitsidwa ndi chingwe choyendetsa galimoto.Gawo latsopanoli liyenera kukhala ndi ulusi womwewo ndi kupanikizika kogwira ntchito, apo ayi crane sidzagwa m'malo kapena sichidzagwira ntchito bwino.
Wolandila galimoto wokhala ndi valavu yokhetsa condensate kumapeto kwa khoma
Zowonjezera (zolimbitsa) ma polima bushings, ma clamps ndi mabatani amathanso kukhazikitsidwa pa sheath ya chingwe - izi ndizomwe zimafunikira pa malo oyenera a chingwe komanso kumangirira kwake pazinthu za thupi kapena chimango chagalimoto.
Monga lamulo, kutalika ndi zizindikiro zina za chingwecho zimasonyezedwa pa chizindikiro chake kapena m'mabuku oyenerera - chidziwitsochi chimathandiza kusankha chingwe chatsopano pamene chakale chikutha.
Kusintha kwa gawolo kuyenera kuchitidwa motsatira malangizo okonza galimoto.Nthawi zambiri, ntchitoyo imachepetsedwa kuti itulutse crane ndi kiyi ndikuyika gawo latsopano m'malo mwake, musanayambe ntchito, ndikofunikira kumasula kukakamizidwa kwadongosolo, ndikuyika crane yatsopano kuyenera kuchitika kudzera mu oyenera O-ring.
Ntchito ya condensate drain valve / valve ndiyosavuta.Ngati tikulankhula za valavu, ndiye kuti kukhetsa condensate, m'pofunika kusuntha tsinde cham'mbali (kapena akanikizire lever wa valavu ndi lever galimoto) ndi kudikira mpweya youma ndi woyera, pambuyo kumasula tsinde. , valavu idzatseka chifukwa cha mphamvu ya kasupe ndi mpweya.Ngati pali faucet pa wolandira, ndiye kuti m'pofunika kutembenuzira chogwirira chake ku "Open" malo, ndipo mutatha kuchotsa chinyezi, tembenuzirani chogwiriracho ku malo "Otsekedwa".Kusamalira koteroko kuyenera kuchitika tsiku lililonse kapena pakufunika.
Ndi kusankha koyenera ndikusintha valavu ya condensate drainage, makina a pneumatic agalimoto, thirakitala kapena zida zina zidzatetezedwa ku chinyezi ndi mafuta pa moyo wonse wautumiki.
