Mwachidule

Timasungabe kuwongolera ndikuwongolera malonda ndi ntchito zathu. Panthawi imodzimodziyo, timagwira ntchito mwakhama kuti tifufuze ndi kukonza Chitoliro cha Chitsulo cha Mechanical, Mothandizidwa ndi kasamalidwe ka mafakitale, bizinesi yakhala ikudzipereka kuthandizira chiyembekezo chokhala mtsogoleri wamsika wamakono m'mafakitale awo. Kudzipereka nthawi zonse ndikofunikira pa ntchito yathu. Nthawi zonse takhala tikugwirizana ndi kutumikira makasitomala, kupanga zolinga zoyendetsera mtengo ndikutsata kuona mtima, kudzipereka, lingaliro lokhazikika loyang'anira.

Kugwiritsa ntchito

Imagwiritsidwa ntchito makamaka pamakina komanso kupanga ma cylinders a gasi, kuphatikiza machubu a kaboni ndi aloyi opanda makina osasunthika, ndipo amakwirira machubu amakina osasunthika komanso oziziritsa komanso osaziziritsa omwe amamaliza kuzizira mpaka kukula kwake ndi kuphatikiza 12 3⁄4 mu. (323.8 mm) kunja kwake kwa machubu ozungulira okhala ndi makulidwe a khoma ngati pakufunika.

Kulekerera

Kulekerera Kunja Kwa Diameter Kwa Machubu Ozungulira Otentha Omaliza^A,B,C

Kulekerera kwa Diameter sikugwira ntchito pazokhazikika komanso kupsya mtima kapena kuzimitsidwa komanso kupsya mtima.

B Mitundu yodziwika bwino yamachubu omalizidwa otentha ndi 1¹⁄2 mu. (38.1 mm) mpaka 10³⁄4 ​​mkati (273.0 mm) kunja kwake ndi makulidwe a khoma osachepera 3 % kapena kupitirira kunja kwake, koma osachepera 0.095 mkati (2.41 mm).

C Zokulirapo zilipo; funsani wopanga kukula kwake ndi zololera.

Kulolera kwa Khoma kwa Kutentha Kwambiri Kwatha

A Khoma makulidwe kulolerana mwina si ntchito pa makoma 0.199 mu. (5.05 mm) ndi zochepa; funsani wopanga zololera pakhoma pamiyeso yotere yamachubu.
gawo lofunika kwambiri, ndiye kuti machubu ozizira amayenera kufotokozedwa m'mimba mwake ndi makulidwe a khoma kapena m'mimba mwake ndi m'mimba mwake.
Machubu Amakina Okhotakhota-Kusiyanasiyana kwa mainchesi akunja ndi makulidwe a khoma sikuyenera kupitilira kulolerana mu Table. Table chimakwirira tolerances monga ntchito m'mimba mwake kunja ndi khoma makulidwe ndi zikugwira ntchito kwa anatchula kukula.
Ground Mechanical Tubing-Kusiyanasiyana kwa diam-eter yakunja sikuyenera kupitilira kulolerana komwe kuli mu Table. Izi nthawi zambiri zimapangidwa kuchokera ku chubu chozizira.
Utali—Machubu amakina nthawi zambiri amaperekedwa muutali wa mphero, 5 ft (1.5 m) ndi kupitirira. Utali wotsimikizika wodulidwa umaperekedwa ngati watchulidwa ndi wogula. Kulekerera kwautali kumawonetsedwa mu Table.
Kuwongoka—Kulolera mowongoka kwa machubu ozungulira opanda msoko sikuyenera kupitilira kuchuluka komwe kwawonetsedwa mu Table.

Chofunikira Choyesa

1.Kuvuta Kuyesa
Pamene malire a kuuma akufunika, wopanga adzafunsidwa. Kuuma kwachizoloŵezi kumatchulidwa mu Table .Pakatchulidwa, kuyesa kuuma kumayenera kuchitidwa pa 1% ya machubu.

2.Mayeso a Tension
Pamene katundu wokhazikika akufunika, wopanga adzafunsidwa. Zomwe zimakhazikika pamagiredi ena omwe amapezeka kwambiri komanso kutentha kwalembedwa patebulo.

3.Mayeso Osawononga
Mitundu yosiyanasiyana ya mayeso osawononga akupanga kapena ma electromagnetic alipo. Mayeso oti agwiritsidwe ntchito ndi malire owunikira adzakhazikitsidwa ndi mgwirizano wa wopanga ndi wogula.

4.Flaring Test
Pakakhala zofunikira zapadera zaukhondo wachitsulo, njira zoyesera ndi malire ovomerezeka zidzakhazikitsidwa ndi mgwirizano wa wopanga ndi wogula.
