Nokuba umthengi omtsha okanye umthengi wakudala, sikholelwa kwintetho ende kunye nolwalamano oluthembekileyoI-China 12mm Gavanile, I-Epoxy Cocar ikhuphe kwakhona kukhuseleko lwe-corrosion, Silandela indlela ebalaseleyo yokuqhubela phambili ezi mveliso ziqinisekisa ukuqina okufanelekileyo kunye nokuthembeka kwesithuthi. Silandela ukuhlamba nje okusebenzayo kwaye silungisa iinkqubo ezivumela ukuba sinikezele ngemilinganiselo engalunganga yezisombululo zabaxumi bethu. Sihlala sizabalazela ukugqibelela kwaye yonke imigudu yethu ijolise ekufezekiseni ukoneliseka kwabathengi ngokupheleleyo.

ukwahlulahlula

Ibha yentsimbi eshushu eshushu yahlulwe yangamaBanga amathathu: HRB335 (IBakala lakudala lingama-20mns), iBakala lesithathu HRB400 (IBakala lakudala (iBanga laBadala liyi-20mnsnb, kunye neBanga lesine le-HRB500.
Zimbini iindlela ezisetyenziswayo zokuhlela zokuqinisa imivalo:Inye kukuhlela ngokwemilo yejometri, kwaye enye kukuhlela okanye ukwahlula-hlula ngokwemilo yomnqamlezo wecandelo lezinto ezixineneyo kunye nokuvalwa kwemivalo. Chwetheza ii-II.

Okwesibini kukuhlelwa kwentsebenzo (ibanga), njengokuphunyezwa okukhoyo ngoku kwilizwe lam, i-repur1499.2-2008 Inqanaba; Kwinqanaba lemizi-mveliso laseJapan (ji sg3112), imivalo yentsimbi yahlulwe ngokwamanqanaba ama-5 ngokweempawu zabo ezibanzi; Kumgangatho weBritane (Bs4461), amabakala amaninzi eemvavanyo zovavanyo lwentsebenzo zichazwe. Ukongeza, imivalo yensimbi inokubekwa ngokusetyenziswa, njengokuvalwa kwentsimbi yentsimbi yokuqiniswa kwekhonkrithi kunye nemivalo yentsimbi ephathwayo yekhonkrithi.

inkalo

1) Uluhlu lweedayala ze-diameter kunye nobubanzi obucetyiswayo
Ububanzi bemigca yensimbi busuka kwi-6 ukuya kwi-50mm, kunye nomgangatho weenqanawa ezinconyelweyo ze-6, 8, 12, 14, 32, kunye ne-50mm.
2) ukuphambuka okuvumelekileyo kobume bomphezulu kunye nobungakanani bebhadi yensimbi yensimbi
Imigaqo yoyilo yemivalo yentsimbi yentsimbi kufuneka ifezekise ezi mfuno zilandelayo:
I-Angle β phakathi kwembambo elinqamlezayo kunye ne-axis yentsimbi akufuneki ukuba ingaphantsi kwama-45 degrees. Xa i-engile equkiweyo ayiphezulu kwe-70 degrees, indlela yokuvalwa kweendawo eziguqukayo kumacala omabini akwibar yentsimbi kufuneka aphathwe ngokuchaseneyo;
Isithuba esithile esiyi-l kwimivalo yokuhamba ngokungafanelekanga ukuba ingabi ngaphezu kwe-0.7 uphinda-phinde.
I-angle α phakathi kwecala le-rib efihlakeleyo kunye nomphezulu webhani yensimbi awuyi kuba ngaphantsi kwama-45 degrees;
Isixa se-GAPS (kubandakanya ububanzi beembambo zexesha elide) kwiziphelo ze-ribes ezinqamlezileyo kumacala aphezulu kwi-bar yensimbi ayiyi kuba ngaphezulu kwe-20% yomjikelezo wentsimbi;
Xa idayimitha etyunjiweyo yebha yentsimbi ayingaphezulu kwe-12mm, indawo ye-rib yesalathisi akufuneki ibe ngaphantsi kwe-0.055; Xa idayimitha yoLungiso i-14mm kunye ne-16mm, indawo ye-rib ye-rib akufuneki ibe ngaphantsi kwe-0.060; Xa idayimitha yoLungu inkulu kune-16mm, indawo ye-rib ye-rib akufuneki ibe ngaphantsi kwe-0.065. Jonga isiHlomelo C sokubalwa kwendawo yerib yesihlobo.
Imivalo yensimbi yensimbi ngokubanzi inemivalo emide, kwaye nakwakhona nawabo bangomvumbi;

3) ubude kunye nokuphambuka okuvumelekileyo
Nye. ubude
Imivalo yensimbi ihlala ihanjiswa ngobude obusisigxina, kwaye ubude bokuhanjiswa kweenkonzo kufuneka ziboniswe kwimvumelwano;
Imivalo yensimbi inokuhanjiswa kwi-roll, uluhlu ngalunye lufanele ukuba lube yibha yentsimbi, kunye ne-5% yenani le-rolls nganye kwi-batch nganye (ngaphantsi kwe-rolls ezimbini) iqulethe imivalo emibini yentsimbi. Ubunzima bediski kunye needayimitha zediski zimiselwa ngokuthetha-thethano phakathi komthengisi kunye nomthengi.
b. Ubude bokunyamezelana
Xa ubude obumiselweyo zisiwe, ukuphambuka okuvumelekileyo kubude bebhani yensimbi ayisiyo ngaphezulu kwe-25mm;
Xa ubude obuncinci obufunekayo, ukuphambuka yi- 50mm;
Xa ubude obukhulu obufunekayo, ukuphambuka kwe--50mm.
c. I-curvature kunye neziphelo
Ukuphela kwebha yentsimbi kufuneka kunqunyulwe ngqo, kwaye ishenxisi yendawo ayiyi kuchaphazela ukusetyenziswa
