Momwe mungasankhire valavu yoyenera yoyendetsedwa ndi woyendetsa
2024-03-26Mu hydraulic system, valve balance imatha kuzindikira kuwongolera chitetezo cha silinda yamafuta, ndipo imatha kutengapo gawo pakuteteza kutayikira ngati chitoliro chamafuta chaphulika.
Ntchito ya valve balance sichimakhudzidwa ndi kupanikizika kwa msana. Pamene kuthamanga kwa doko la valve kukuwonjezeka, kungathenso kusunga kutseguka kokhazikika kwapakati pa valve.
Nthawi zambiri imathanso kugwira ntchito yoteteza kusefukira kwadera. Nthawi zambiri amagwiritsidwa ntchito poyang'anira njira zofananira.
Ndibwino kuti muyike valve yotsalira pafupi ndi silinda kuti muwonjezere zotsatira zake.
Valavu imodzi yolumikizira imatha kuwongolera katundu woyenda mozungulira, monga nsanja zonyamulira, ma cranes, ndi zina zambiri.
The double balancer imawongolera katundu wobwereza komanso wozungulira monga ma wheel motors kapena masilinda apakati.
1. Chiŵerengero chotsogolera chili motere:
① 3: 1 (muyezo) Yoyenera pakachitika zosintha zazikulu komanso kukhazikika kwamakina aukadaulo.
②8: 1 ndi yoyenera pamikhalidwe yomwe katunduyo amafunikira kuti azikhala osasintha.
2. Mfundo yogwira ntchito
Mbali ya valve ya njira imodzi imalola kuti mafuta opanikizika aziyenda momasuka mu silinda pamene amalepheretsa kutuluka kwa mafuta. Gawo loyendetsa ndege limatha kuwongolera kuyenda pambuyo pokhazikitsa kukakamiza kwa woyendetsa. Gawo loyendetsa ndege nthawi zambiri limayikidwa ku mawonekedwe otseguka, ndipo kupanikizika kumayikidwa ku 1.3 nthawi yamtengo wapatali, koma kutsegulidwa kwa valve kumatsimikiziridwa ndi chiwerengero cha oyendetsa ndege.
Kuti muwongolere bwino katundu ndi kugwiritsa ntchito mphamvu zosiyanasiyana, magawo osiyanasiyana oyendetsa ayenera kusankhidwa.
Chitsimikizo cha mtengo wotsegulira wothamanga wa valve ndi mtengo wamtengo wapatali wa kayendedwe ka silinda amapezedwa motsatira ndondomeko yotsatirayi: chiŵerengero cha oyendetsa ndege = [(kukhazikitsa kupanikizika kwa mpumulo) - (kuthamanga kwa katundu)] / kuthamanga kwa ndege.
Chiŵerengero cha hydraulic control ratio cha valve balance chimatchedwanso pilot pressure ratio, yomwe imatchedwanso pilot ratio mu Chingerezi. Zimatanthawuza chiŵerengero cha mtengo wotsegulira wothamanga wa valve yoyendetsera mafuta pamene mafuta oyendetsa ndege ali 0 pambuyo pa kasupe wa valve yokhazikika kuyikidwa pamtengo wokhazikika komanso mtengo wake woyendetsa pamene valavu yokhala ndi mafuta oyendetsa imatsegulidwa kumbuyo. .
Mikhalidwe yosiyanasiyana yogwirira ntchito ndi malo amafunikira kusankha kosiyanasiyana kwa kuchuluka kwa kuthamanga. Pamene katunduyo ndi wosavuta komanso kusokoneza kwakunja kumakhala kochepa, chiwerengero chachikulu cha hydraulic control ratio chimasankhidwa, chomwe chingachepetse mtengo woyendetsa ndege ndikupulumutsa mphamvu.
M'malo omwe kusokoneza kwa katundu kumakhala kwakukulu ndipo kugwedezeka kumakhala kosavuta, kagawo kakang'ono kameneka kamasankhidwa kuti atsimikizire kuti kusinthasintha kwa oyendetsa ndege sikungayambitse kugwedezeka kwa valve core.
3. Mwachidule
Chiŵerengero cha woyendetsa ndi gawo lofunikira pakugwira ntchito kwa hydraulic system. Zingakhudze mphamvu yotseka ndi mphamvu yotsegula, kutseka ntchito ndi moyo wautumiki wa valve balance. Chifukwa chake, pakusankha ndi kugwiritsa ntchito valavu yofananira, ndikofunikira kuganizira mozama momwe zimakhudzirachiŵerengero cha woyendetsapa ntchito yake ndikusankha chiŵerengero choyenera cha oyendetsa ndege kuti atsimikizire kugwira ntchito kodalirika kwa valve yoyendetsa.
