Kusiyanitsa pakati pa mavavu okhala ndi mpando umodzi ndi awiri

Wokhala Mmodzi

Mavavu okhala ndi amodzi ndi mtundu umodzi wa ma valve padziko lonse lapansi omwe ndiofala kwambiri komanso osavuta kupanga.Ma valve amenewa ali ndi ziwalo zochepa zamkati.Amakhalanso ang'onoang'ono kuposa ma valve okhala pawiri ndipo amapereka kutseka kwabwino.
Kukonza kumakhala kosavuta chifukwa chosavuta kupeza ndi kulowa pamwamba pazigawo za valve.Chifukwa cha kugwiritsiridwa ntchito kwawo kwakukulu, amapezeka m'makonzedwe osiyanasiyana a trim, choncho pali mitundu yambiri yamayendedwe othamanga.Amapanganso kugwedezeka kochepa chifukwa cha kuchepa kwa plug mass.

Ubwino wake

- Mapangidwe osavuta.
- Kukonza kosavuta.
- Yaing'ono komanso yopepuka.
- Kutsekedwa kwabwino.

Akhala Pawiri

Mapangidwe ena amtundu wa ma valve padziko lonse lapansi amakhala pawiri.Mwanjira iyi, pali mapulagi awiri ndi mipando iwiri yomwe imagwira ntchito mkati mwa thupi la valve.Mu valavu imodzi yokhala pansi, mphamvu za mtsinje wothamanga zimatha kukankhira pulagi, zomwe zimafuna mphamvu yaikulu ya actuator kuti igwiritse ntchito kayendedwe ka valve.Ma valve okhala pawiri amagwiritsa ntchito mphamvu zotsutsana kuchokera kumapulagi awiriwa kuti achepetse mphamvu ya actuator yofunikira kuti aziyendetsa.Kulinganiza ndi mawu omwe amagwiritsidwa ntchito pamene mphamvu ya ukonde pa
tsinde limachepetsedwa mwanjira iyi.Ma valve awa sali olinganizika kwenikweni.Zotsatira za mphamvu za hydrostatic pamapulagi sizingakhale ziro chifukwa cha geometry ndi mphamvu.Chifukwa chake amatchedwa senced.Ndikofunikira kudziwa kutsitsa kophatikizana chifukwa cha kuchuluka kwa kusanja komanso mphamvu zosunthika mukamayesa makinawo.Shutoff ndi osauka ndi valavu okhala pawiri ndipo ndi mmodzi wa downfalls ndi mtundu uwu wa zomangamanga.Ngakhale kulolerana kwa kupanga kungakhale kolimba, chifukwa cha mphamvu zosiyana pa mapulagi sizingatheke kuti mapulagi onse agwirizane nthawi imodzi.Kukonzekera kumawonjezeka ndi zowonjezera zamkati zomwe zimafunikira.Komanso ma valve awa amakhala olemera kwambiri komanso akuluakulu.
Mavavu awa ndi mapangidwe akale omwe ali ndi zabwino zochepa poyerekeza ndi zovuta zomwe zidabadwa.Ngakhale angapezeke m'makina akale, sagwiritsidwa ntchito kawirikawiri m'mapulogalamu atsopano.

Ubwino wake

- Kuchepetsa mphamvu ya actuator chifukwa cha kusanja.
- Zochita zimasinthidwa mosavuta (Direct / Reverse).
- Kuthamanga kwakukulu.

Zoipa

- Kutseka koyipa.
- Zolemera komanso zazikulu.
- Zida zambiri zogwirira ntchito.
- Yopanda malire.
