Kodi kuthamanga kwa woyendetsa kumakhudza bwanji valavu yopingasa?
2024-03-14Chiŵerengero cha oyendetsa ndege cha counterbalance valve ndi chiŵerengero cha malo oyendetsa ndege ndi malo osefukira, zomwe zikutanthauza kuti mtengo uwu umakhalanso wofanana ndi: pamene kasupe wa valve counterbalance ayikidwa pamtengo wokhazikika, kukakamizidwa kofunikira kuti mutsegule pamene pali. palibe mafuta oyendetsa ndege ndipo mafuta oyendetsa okha amatsegula chiŵerengero cha kuthamanga.
Pamene palibe mafuta oponderezedwa mu doko lamafuta oyendetsa, kutsegulira koyenera ndi mtengo wokhazikika wa masika. Ngati palibe mafuta oyendetsa ndege, valve yoyendetsera bwino imatsegulidwa ndi katundu, ndipo kutsika kwapakati kudzawonjezeka kwambiri pamene kuthamanga kwa magazi kumawonjezeka (izi zimagwiritsidwanso ntchito poyendetsa katundu). Ngati chikoka cha kutulutsa kotulutsa sichikuganiziridwa, kuthamanga kwa woyendetsa = (mtengo wapatali - katundu) / chiŵerengero cha dera. Ngati woyendetsa wamkati agwiritsidwa ntchito, kuthamanga kotsegulira kungathe kukhazikitsidwa mwa kusintha bolt ya valve yothandizira.
ndondomeko yeniyeni
Kuthamanga kotsegula = (kupanikizika kwakukulu - kuthamanga kwakukulu) / chiŵerengero choyendetsa cha valve
Kwa valavu yamagetsi, ngati chiwongolero chake chowongolera ndi 3: 1, pali mgwirizano wa 3: 1 pakati pa mafuta oyendetsa ndege ndi malo opanikizika omwe akugwirizana ndi chigawo cha valve chotsegulira mafuta, kotero mphamvu yolamulira imafunika kutsegula pakati. ayenera kukhala otsika, ndi kulamulira Chiŵerengero cha kupanikizika kwa kupanikizika kumene mafuta olowera amatsegula spool ndi pafupifupi 1: 3.
Mtsogoleli wotsogola
3: 1 (muyezo) Yoyenera pamikhalidwe yokhala ndi kusintha kwakukulu kwa katundu komanso kukhazikika kwa katundu wamakina aukadaulo.
8: 1 ndi yoyenera pamikhalidwe yomwe kufunikira kwa katundu kumakhalabe kosasintha.
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. Pakakhala kusokoneza kwakukulu kwa katundu ndi kugwedezeka kosavuta, chiŵerengero chaching'ono cha kuthamanga chimasankhidwa kuti zitsimikizire kuti kusinthasintha kwa kuthamanga kwa oyendetsa ndege sikungayambitse kugwedezeka pafupipafupi kwavalve yotsutsanapachimake.
Zomwe muyenera kuziganizira posankha valavu yotsutsana:
1. Mtengo wothamanga ukhoza kukhala wokwera pang'ono kuposa mlingo wothamanga;
2. Gwiritsani ntchito valve yokhala ndi chiwerengero chochepa cha oyendetsa ndege momwe mungathere, chomwe chimakhala chokhazikika;
3. Valve yokwanira imagwiritsidwa ntchito kuwongolera kuthamanga, osati kuthamanga;
4. Zitsenderezo zonse zimatsegula zitsenderezo;
5. Sichingagwiritsidwe ntchito ngati valve yothandizira;
6. Khalani pafupi ndi chowotchera momwe mungathere kuti payipi isaphulike.
