Mavavu apadziko lonse Zimayendetsedwa ndi chopukutira m'manja komanso zimawongolera kayendedwe ka madzi. Komabe, zimapangitsanso kupanikizika kwakukulu.
Kusankha valavu yoyenera ndikofunikira, chifukwa mitundu yosiyanasiyana imagwira ntchito zosiyanasiyana komanso magwiritsidwe. Ochepa mwa iwo ali ndi zigawo ziwiri zokha: zotseguka kapena zotsekedwa. Zina zimathandizira kufalikira kwamadzimadzi ndi kuthamanga kuti kusinthidwe. Mavavu apadera amachititsanso kuchuluka kwamavuto. Kutengera mawonekedwe, zofunikira zimafunikira.
Mmodzi mwa mitundu ya mavavu ambiri ndi valavu lapansi. Munkhani yayifupi iyi, tikufotokozera momwe ma valvu apadziko lonse amagwirira ntchito, kuphatikiza maubwino ndi kutsika kwake.

Kodi valavu yapadziko lonse lapansi ndi chiyani, komanso imagwira ntchito bwanji?
Kuti musankhe ngati valavu yapadziko lonse lapansi ili yoyenera kuti mugwiritse ntchito, ganizirani zofunikira zake zitatu. Poyamba, mavavu am'mbali, omwe amawonetsa kuti amatseguka kapena kutseka kutengera kayendedwe ka tsinde. Chachiwiri, amalola, kusiya, kapena kuyendetsa madzi. Mavavu ena amangotseguka komanso kutseka mayiko, koma ma valve apadziko lonse amatha kupotokola osayimitsa. Chachitatu, zimapangitsa kuti mutu uwonongeke kwambiri poyerekeza ndi ma valve ena osiyanasiyana, tradeoff yothandizira.
Momwe ma valve ma globe amagwirira ntchito
Kuchokera panja, ma valavu apadziko lapansi ali ndi zinthu zitatu, chopondera dzanja, chovala, ndi thupi. Bonetiyo imakhala ndi tsinde, komanso pomwe chopukutira m'manja chimatembenuzidwa, tsinde limasokonekera ndikutsika mu bonnet. Mapeto a tsinde ali ndi kachigawo kakang'ono kotchedwa disk kapena pulagi, komwe kumatha kukhala kwachitsulo kapena kosakhala kwazitsulo ndipo kumatha kupezeka m'njira zosiyanasiyana, kutengera kufunikira.
Zina mwazabwino za ma valve apadziko lapansi ndi kuthekera kwawo kupachika kapena kuwongolera mayendedwe. Kupatula kutsekedwa kapena kutseguka, amathanso kutseguka pang'ono. Izi zimakulolani kuti musinthe makope osasiya kwathunthu.
Mavuto akulu apadziko lonse lapansi ndi omwe amawononga mutu kwambiri. Kutayika kwamutu, komwe kumatchedwanso kutaya kwa nkhawa, kumatanthauza kuchuluka kwa zokumana nazo zamadzimadzi momwe zimadutsira mapaipi. Kulimbana kwambiri, kupanikizika kwambiri komwe kumatayika. Mphamvu yokoka, mikangano (yamadzi motsutsana ndi makoma a chitoliro), komanso chipwirikiti zonse zimayambitsa kutayika uku. Mavavu ndi zovekera zimayambitsa kupsyinjika makamaka chifukwa cha chipwirikiti.
Mavavu apagulu amakakamiza madzimadzi kuti asinthe malangizo akamadutsa, ndikupanga kuwonongeka ndi chipwirikiti. Kuchuluka kwakutayika kumadalira pazinthu monga kuchuluka kwa madzi ndi kusisita kusiyanasiyana. Komabe, ndizotheka kuwunikiranso zovuta zomwe zimachokera pamagetsi osiyanasiyana pogwiritsa ntchito metric yotchedwa coefficient ya L / D.
Nthawi yogwiritsa ntchito ma valve apadziko lonse
Ma valavu apadziko lonse lapansi ndi abwino nthawi iliyonse mukafunika kuyendetsa pang'onopang'ono, komabe simuyenera kupsinjika chifukwa cha kuchuluka kwa kupsinjika. Ntchito zina ndi monga:
Makina oziziritsa mpweya
Mafuta machitidwe
Madzi a feed feed komanso makina azakudya zamagulu
Makina opanga mafuta opangira mafuta
Kokani mapaipi ndikuchepetsanso mapulogalamu owaza moto kapena njira zina zotetezera moto
Mavavu apadziko lonse lapansi siosankhidwa bwino oyang'anira ma valve pamagetsi owaza moto, pomwe kukakamizidwa kumapita patsogolo. M'malo mwake, mavavu agulugufe amagwiritsidwa ntchito pafupipafupi.
