Makhalidwe aukadaulo a gaiter

Chenjezo Lofunika: Awa ndi mawu osungira zakale, osati makina amakono, kuwerengetsa mphamvu, kuwunika zoopsa kapena buku logwiritsa ntchito. Njira zolimbikitsira, zitsanzo, miyeso, kuthamanga, njira, zoyesa ndi njira ziyenera kuyang’aniridwa molingana ndi malamulo omwe akugwiritsidwa ntchito, zolemba za opanga ndi malamulo otetezeka a ntchito.

Mawu awa sikuti akungoperekedwa ndi makina, zoyesa kapena zolemba zantchito za Savo Kusić. Zomwe zilipo pano zikuyang’ana mazenera, zitseko ndi mayankho ogwirizana nawo.

Kulimbitsa macheka mu chimango

Pokhala ndi machubu, machekawo ayenera kutetezedwa bwino komanso kukhazikika mu chimango. Mukamagwira ntchito ndi macheka osalimba, shard mu mawonekedwe a wavy odulidwa, etc. Njira yodziwika kwambiri yomangirira macheka ndi mphero, eccentric, screw (Mkuyu.1), komanso njira yomangirira pogwiritsa ntchito zida zama hydraulic. Kumanga macheka ndi wedges ndikoipa kuposa njira zina. Mafakitale ambiri amatulutsa mitundu yambiri ya macheka amphamvu, othamanga, obala kwambiri. Macheka ocheka kwambiriwa amagwira ntchito m’mafakitale akuluakulu opangira matabwa m’makampani omanga. Makhalidwe aukadaulo a ma gaiters awa amaperekedwa patebulo1.

Chithunzi 1: Kulimbitsa macheka pachipata

Mitundu ikuluikulu yazipata zopangira zambiri

Macheka opepuka otsika pang’ono amagwiritsidwa ntchito podula mitengo m’malo omanga akumidzi komanso m’mabizinesi ang’onoang’ono kuti apange zinthu zomanga kuchokera kumatabwa. Makhalidwe a ana ochita masewerawa ali patebulo 2. 

Zipata Zowala

Kupanga kwa Gator kumawerengeredwa motsatira fomula: P = K -  Δtnq/1000L m3. Kumene K ndiye gawo logwiritsira ntchito zipata. Kwa zingwe zamakina K = 0.93, ndi zapakati-makina K = 0.90;  Δ - kusamutsidwa kwa kutembenukira kumodzi kwa shaft pachipata; n - chiwerengero cha kusinthika kwa shaft pachipata pamphindi; t - gater ntchito nthawi mu mphindi; q - chipika voliyumu, m3; L - kutalika kwa zipika, m.

Mawerengedwe a mbiri ya zokolola

Pozindikira kuchuluka kwapachaka kwa chipata pakusintha kumodzi, kuyimitsidwa, komwe kumachitika chifukwa cha zifukwa zosiyanasiyana (kukonza, kusowa kwa zida, ndi zina zotero) kuyenera kuganiziridwa. Kutayika kumeneku kumatsimikiziridwa ndi koyegeti yoyesera Kgod = 0.9 - 0.92.

Chifukwa chake, kuchuluka kwapachaka kwa mlonda wapakhomo pakusintha kumodzi kumatsimikiziridwa ndi njira P = Kgod x K x Δntq/1000L m3 pa shift imodzi.

Kapangidwe ka macheka a zipata zaperekedwa patebulo 3.

Makulidwe ndi mbiri ya ma saws

Macheka amapangidwa mumitundu iwiri ya mano: yokhala ndi m’mphepete wam’mbuyo komanso wowongoka kumbuyo (mkuyu.2). Posankha miyeso yofunikira ya macheka, muyenera kutsogoleredwa ndi kutalika kwa chimango cha chipata, kukula kwake ndi kukula kwa zipika zomwe ziyenera kudulidwa. Kutalika kofunikira kwa macheka kumatha kutsimikiziridwa ndi formula L = Dmax + H + (300ku350) mm, pamene L ndi kutalika kwa macheka, mm; Dmax - kutalika kwakukulu kwa zipika zomwe ziyenera kudulidwa;300-350- chilolezo chifukwa cha kukhazikitsa zoyikapo matabwa ndi battens; H - kutalika kwa sitiroko, mm.

Chithunzi2: Mbiri ya mano a macheka

Kuchindikala kwa macheka ndi phula la mano ziyenera kugwirizana ndi kutalika kwa chodulidwacho ndi mtundu wa odulidwawo. Ubale woterewu ukuperekedwa mu tebulo4. 

Machekawo amaikidwa pamodzi ndi zomangira zomwe zimamangiriza kumunsi kwa macheka ndi seti ya ma stirrups aŵiri ndi ma bolt asanu ndi awiri kumtunda. Ma stirrups amamangiriridwa ku macheka pamakona ake akumbuyo kumbuyo kwake. Mphepete zopindika za chipwirikiti ziyenera kuyang’anizana. Asananyamule chipwirikiticho, m’mbali mwa machekawo azifufuzidwa kuti awone ngati ndi zowongoka komanso zofananira, ndipo ngati sizili zofanana, azidula pamakina onola macheka.
