Indlela yokuthenga umtjhini omuhle wezitina

Ukuzwisisa Umtjhini wokwenza iintina, kufuze siqale sizwisise ukwakheka komtjhini wezitina. Umtjhini wezitina wakhiwe: umtjhini omkhulu, umtjhini wendwangu, umthombo wepuleti, isikhunta, isitetjhi sepompo, ihlelo lokulawula ikhomphyutha. Umsebenzi omkhulu womtjhini kuthwala umzimba omkhulu womtjhini wezitina. Isekela yoke imitjhini esizako ukusuka phezulu ukuya phasi begodu ukusuka emuva ukuya phambili. Umtjhini wendwangu udlala indima yokuphakela indwangu, engafaka ngokuzeleko izinto ezisetjenziswako ngaphakathi kwesikhunta. Isikhunta siyatlhogeka emhlobeni ngamunye wesitina. Umtjhini wokuphakela amashidi udlala indima yokujika iphalethi bese uthumela ibhodi phasi kwesikhunta. Bese, umkhiqizo oqediweko uthunyelwa ukusuka ngaphasi kwesikhunta ukuya emotweni yokuthutha. Isitetjhi sempompo siyinhliziyo yohlelo lwamanzi. Yiwo amandla wokulawula ngamunye. Ikhomphyutha yingqondo yomtjhini woke wezitina, okungumgogodla. Zoke iinkhathi zinekhomphyutha yazo yokulawula eqediweko.

Woke umuntu uyazi bona ngaphezu komraro wentengo lokha nawuthenga umtjhini wezitina zesamente, ikhwalithi yomtjhini wezitina nayo iqakatheke khulu, kodwana amakhasimende amanengi amatjha awazi bona angayihlola njani umtjhini wezitina lokha nabathenga umtjhini wezitina. Namhlanjesi, njengomthengisi wemitjhini yokwenza iintina. Akhe sikhulume ngokuthi ungayithenga njani umtjhini omuhle wezitina zesamente nokuthi khuyini okufanele uyiqaphele lokha nawuthenga umtjhini wezitina zesamende.

1. Irherho lokudlulisa kufanele libe liguquguqukako begodu akukafaneli libe nomdumo ongakajayeleki.

2. Akukafaneli kuvunyelwe ukuvuza kwamafutha kizo zoke iingcenye. Indawo epheleleko yokuvuza kwamafutha wengcenye yokudlulisa umtjhini akukafaneli idlule indawo yinye, begodu indawo yokuvuza yamafutha yoke yengcenye yokudlulisa ngamanzi akukafaneli idlule iindawo ezimbili.

.

4. Ukwamukela ihlelo lokudlulisa nge-belt drive, i-pulley kufanele iqondiswe, amandla alingana, begodu ukulungiswa kwe-elastic kungenziwa lula.

5. Ikholomu yomhlahlandlela igcotshwe kuhle, ifaneleka kuhle, ayikho ukujamelana ngesikhathi sokusebenza, ayikho ukuzamazama!

6. Isinciphisi sejubane singasebenza ngokuragela phambili i-awa elilodwa ngaphasi kobujamo bokusebenza obulinganisiweko. Ukunyuka kwamazinga womtjhiso we-oyili yokunciphisa igiya akukafaneli kudlule ama-degrees ama-40 we-Celsius. Ukukhuphuka kwamazinga womtjhiso we-oyile yokunciphisa i-turbine akukafaneli kudlule ama-degrees ama-60, begodu amazinga womtjhiso aphezulu we-oli akukafaneli adlule ama-degrees ama-85!

.

Ikhwalithi yokubukeka komtjhini wezitina zesamende kufanele ihlangabezane neemfuneko ezilandelako:

1. Ipende kufanele ibe yinto efanako, iphaphathekile begodu ibe mhlophe. Ingaphezulu kufanele libe lome begodu linganamatheli. Akukafaneli kube nemibimbi, ukutjhwaba, ukuvuza kwepende, amatshwayo wokugeleza, amabhamuza, njll.

.

3. Iingcenye ezivulekileko zeengcenye kufanele ziphathwe ngendlela yokulwisana nokugqwala. Ingaphezulu lama-casting kufanele libe bushelelezi begodu libushelelezi. Akukafaneli kube nama-burrs aphazimako afana namabhamuza, ama-stomata, kanye nama-appetite protrusions.

Siphinde sibe nomfutho ophakemeko Umtjhini wokwenza amabhlogo kuyathengiswa, wamukelekile ukuza kithi.
