Pamene kuyatsa kwa makina osakaniza phula sikukwanira, kugwiritsira ntchito mafuta a petulo ndi dizilo kumawonjezeka, zomwe zimabweretsa kuwonjezeka kwa mtengo wa mankhwala; mafuta otsala amafuta nthawi zambiri amawononga zida zomalizidwa, zomwe zimapangitsa kuti pakhale ndalama zomalizidwa; pamene kuyatsa sikukwanira, mpweya wotuluka umakhala ndi utsi wowotcherera. Utsi wowotcherera ukakumana ndi thumba lotolera fumbi mu zida zochotsera fumbi, umamatira kunja kwa thumba la fumbi, kuwononga thumba la fumbi, kupangitsa kuti chowotcha chotenthetsera chitsekedwe ndikuyatsa kosakwanira, komwe kumatha pamapeto pake zimabweretsa hemiplegia. Zida sizingapangidwe.
Ngati ingathe kusungidwa bwino, ikhoza kupulumutsa ndalama zambiri ndikuwonjezera moyo wautumiki wa makina oyaka moto. Ndiye, chifukwa chiyani pakuyaka kosakwanira? Kodi kuthetsa izo?

Mafuta abwino
Mafuta amafuta omwe amagwiritsidwa ntchito nthawi zambiri pamakina osakaniza konkire a asphalt amaphatikizidwa ndi ogulitsa mafuta omwe amaperekedwa pogwiritsa ntchito mafuta okhazikika komanso othandizira kuyaka ndi zoteteza zina. Zosakaniza ndizovuta kwambiri. Malingana ndi zochitika zomwe zimagwiritsidwa ntchito pa malo, mafuta a mafuta amatha kuonetsetsa kuti chowotcha chimagwira ntchito bwino ndipo chimayatsidwa mokwanira pokwaniritsa zotsatirazi: mtengo wa calorific si wochepera 9600kcal /kg; kukhuthala kwa kinematic pa 50 ° C sikuposa 180 cst; makina zotsalira zili zosaposa 0,3%; chinyezi sichidutsa 3%.
Pakati pazigawo zinayi zomwe zili pamwambazi, chiwerengero cha calorific value parameter ndi chofunikira kuti chiwotcha chikhoza kupereka chiwerengero cha calorific. The kinematic mamasukidwe akayendedwe, makina zotsalira ndi chinyezi magawo mwachindunji amakhudza poyatsira yunifolomu; kinematic viscosity, makina Ngati mawonekedwe ndi chinyezi cha zotsalira za zida zikupitilira muyezo, mphamvu ya atomization yamafuta pamoto wowotcha idzakhala yoyipa, utsi wowotcherera sungathe kusakanikirana ndi gasi, ndipo kuyatsa mopanda tsankho sikungatheke. wotsimikizika.
Kuonetsetsa kuyatsa mopanda tsankho, zofunikira pamwambapa ziyenera kukumana posankha mafuta amafuta.

Wowotcha
Zotsatira za atomization pa kukhazikika kwa moto
Mafuta opepuka amafuta amawapopera ngati nkhungu kudzera mumphuno ya atomizing yamfuti yamafuta mokakamizidwa ndi pampu yamafuta kapena kuyanjana pakati pa pampu yamafuta ndi mpweya wothamanga kwambiri. Kukula kwa kuwotcherera fume particles kumadalira mphamvu ya atomization. Mphamvu yoyatsira ndi yoyipa, tinthu tating'onoting'ono tating'onoting'ono, ndipo malo olumikizirana ndi gasi ndi ochepa, kotero kuti kuyatsa kumakhala koyipa.
Kuphatikiza pa kinematic viscosity ya mafuta opepuka omwe tawatchula kale, palinso zinthu zitatu zomwe zimakhudza mphamvu ya atomization ya mafuta opepuka omwe amachokera ku chowotcha chokha: dothi limakakamira mumphuno yamfuti kapena lawonongeka kwambiri; pampu yamafuta Kuwonongeka kwakukulu kapena kulephera kwa zida za thiransifoma kumapangitsa kuti kuthamanga kwa nthunzi kukhale kotsika kuposa kuthamanga kwa atomization; Kuthamanga kwa mpweya wothamanga kwambiri womwe umagwiritsidwa ntchito pa atomization ndi wotsika kuposa mphamvu ya atomization.
Njira zofananira ndi izi: kutsuka mphuno kuti muchotse litsiro kapena kusintha mphuno; sinthani pampu yamafuta kapena chotsani cholakwika cha thiransifoma; sinthani kupanikizika kwa mpweya kumtengo wokhazikika.

Ng'oma youma
Kufananiza kwa mawonekedwe amoto wamoto ndi mawonekedwe a nsalu yotchinga mu ng'oma youma zimakhudza kwambiri kuyatsa kufanana. Lawi loyatsa la chowotchera limafuna malo enaake. Ngati pali zinthu zina zomwe zikukhala mu dangali, zidzakhudza mbadwo wamba wamoto. Monga malo oyatsira ng'oma youma, imapereka mpata woyatsira wamba kuti upangitse malawi. Ngati pali chinsalu m'derali, zinthu zomwe zikugwa mosalekeza zidzatsekereza lawi lamoto ndikuwononga kufanana kwamoto.
Pali njira ziwiri zothetsera vutoli: imodzi ndiyo kusintha mawonekedwe a lawi lamoto posintha mbali ya atomization ya mphuno yamoto kapena kusintha valavu yowonjezera mpweya yomwe imayang'anira mawonekedwe a lawi, kuti lawi lisinthe kuchoka ku lalitali ndi lopyapyala. wamfupi ndi wandiweyani; china ndikusintha nsalu yotchinga mu poyatsira ng'oma youma posintha zinthu zonyamulira tsamba kuti musinthe nsalu yotchinga m'derali kuchokera wandiweyani kupita pang'onopang'ono kapena opanda nsalu yotchinga kuti ipereke malo okwanira lawi loyatsira.

Zida zochotsera fumbi za fan
Kufananiza kwa zida zochotsa fumbi zoyeserera komanso chowotcha kumathandizanso kwambiri pakuyatsa kufanana. Zida zochotsera fumbi za phula la asphalt konkire zimapangidwira kuti zizitha kuyamwa nthawi yomweyo mpweya wotulutsa wopangidwa ndi chowotchera pambuyo poyatsa, ndikupereka malo ena kuti uyatsire. Ngati payipi ndi zida zochotsera fumbi za zida zochotsa fumbi zoyeserera zatsekedwa kapena payipi yatsekeredwa, mpweya wotuluka pachowotchera udzatsekedwa kapena wosakwanira, ndipo mpweya wotulutsa upitilire kudziunjikira pamalo oyatsira ?? ng'oma youma, kutengera malo oyatsira ndikupangitsa kuyatsa kosakwanira.
Njira yothetsera vutoli ndi: tsegulani mapaipi otsekedwa otsekedwa kapena zida zochotsera fumbi kuti mutsimikize kuyenda bwino kwa fani yokakamiza. Ngati payipi yadutsa mpweya, malo olowera mpweya ayenera kulumikizidwa.
