Pakuumbwa kwedhiri rinoenderera mberi, kumanikidzwa kwechinhu chisina chinhu, mamiriro ekumanikidzwa, uye zvinhu zvakagadzirwa zvese zvinokanganisa kugona kuwana mhedzisiro yakatambanudzwa nguva dzose pasina kukwinya.
Mubvunzo: Tiri kudhirowa makapu kubva kusimbi isingatsvi yegiredhi 304. Pakumira kwekutanga kwedhishi redu rinofambira mberi, tinodhirowa kusvika pakadzika kwemainji angangoita 0.75. Pandinoongorora ukobvu hwemupendero weflange wechinhu chisina chinhu, musiyano kubva kudivi kuenda kudivi unogona kusvika 0.003 inches. Kurova kwega kwega kwakasiyana uye hakuonekwi panzvimbo imwe chete. Ndakaudzwa kuti zvine chekuita nekugadzirisa zvinhu zvisina kugadzirwa, pamwe kumucheto kwekunze kwecoil huru. Tingawana sei kapu ine chimiro chakafanana pasina kukwinya?
A: Ndinoona mubvunzo wako uchimutsa mibvunzo miviri: yekutanga, shanduko dzaunowana mukuita kwerotari, uye yechipiri, zvinhu zvakagadzirwa uye zvirevo zvazvo.
Mubvunzo wekutanga unobata nezvikanganiso zvikuru pakugadzira zvishandiso, saka ngationgororei zvinhu zvepakutanga. Kuchinja kwehukobvu hwemakapu panguva imwe chete uye ukobvu hwemakapu mushure mekudhirowa kunoratidza kuti hapana maburi ekushandisa akakodzera munzvimbo yako yekudhirowa. Pasina kuona dhizaini yako yedhirowa, ndingafunga kuti dhirowa rako rinobaya nedhirowa uye maburi aro anosangana nematanho ese ekugadzira.
Mukudhirowa kwakadzika, gomba risina chinhu rinoiswa pakati pedhiraivha yekudhirowa nechibatiso chisina chinhu, ukuwo dhiraivha yekudhirowa ichidhonza chinhu chacho mudhiraivha yekudhirowa, ichichidhonza chakatenderedza radius yekudhirowa kuti chigadzire goko. Pane kukakavadzana kwakawanda pakati pedhiraivha nechibatiso chisina chinhu. Munguva iyi, chinhu chacho chinomanikidzwa kumativi, ndicho chikonzero chekukwinya nekureba kwedhiraivha yekuvharwa ichipesana nekuyerera kwechibatiso. Kana kumanikidzwa kwekubata kwakakwira zvakanyanya, chinhu chacho chinotyoka nekudhonzwa kwechibatiso chekutambanudza. Kana chakaderera zvakanyanya, kukwinya kuchaitika.
Pane muganho uri pakati pedhayamita yegoko nedhayamita isina chinhu isingapfuure kuti kudhirowa kubudirire. Muganho uyu unosiyana zvichienderana nekureba kwechinhu chacho. Mutemo mukuru ndewekuti 55% kusvika 60% yekudhirowa kwekutanga uye 20% yekudhirowa kwega kwega kunotevera. Mufananidzo 1 inzira yakajairika yekuverenga kumanikidzwa kwechinhu chisina chinhu chinodiwa pakutambanudza (Ndinogara ndichiwedzera simba rekuwedzera rinenge 30% sechinochengetedza, chinogona kuderedzwa kana zvichidikanwa, asi zvakaoma kuwedzera mushure mekunge dhizaini yapera).
Kumanikidzwa kwechinhu chisina chinhu p i2.5 N/mm2 yesimbi, 2.0 kusvika 2.4 N/mm2 yemhangura dzakasanganiswa uye 1.2 kusvika 1.5 N/mm2 yearuminiyamu dzakasanganiswa.
Kusiyana kweukobvu hweflange kunoratidzawo kuti dhizaini yezvishandiso zvako haina kusimba zvakakwana. Bhutsu dzako dzechigadzirwa dzinofanira kunge dzakakora zvakakwana kuti dzikwanise kudhonzwa pasina kusungwa. Zvitsigiro zviri pasi pechigadziko chedhie zvinofanira kunge zvakasimba uye mapini ekutungamira zvishandiso anofanira kunge akakura zvakakwana kudzivirira chero kufamba kwezvishandiso zvepamusoro nepazasi panguva yekutambanudza.
Tarisawo nhau dzako. Kana magidhi ekudhindisa akasakara uye asina kurongeka, hazvina basa kana chishandiso chako chakasimba - hauzobudiriri. Tarisa siraidhi yekudhindisa kuti uve nechokwadi chekuti kureba kwese kwekudhindisa kwacho ndekwechokwadi uye kwakaenzana. Iva nechokwadi chekuti mafuta ekudhirowa ako akasefetwa zvakanaka uye akachengetedzwa, uye kuti huwandu hwekushandisa chishandiso nenzvimbo yemuromo zvakagadzika. Ongorora zvakakwana zvishandiso zvese zvekudhindisa kuti uve nechokwadi chekuti pamusoro pechinhu, kuputira, uye kuenzanisa kwakakodzera. Uye nyatsoteerera radii yekudhirowa; geometry yavo nekupedzisa kwepamusoro zvinofanira kunge zvakakwana.
Uyewo, kunyange hazvo vatengi vachiona 304L ne standard 304 sedzinochinjika, 304L ndiyo sarudzo iri nani yekudhirowa. L inomiririra low carbon, iyo inopa 304L simba rekugova re 0.2% ye 35 KSI uye 304 ye 0.2% ye 42 KSI. Nekudzikira kwe 16% musimba rekugova, 304L inoda simba shoma kuti igovane pakuumba nekugadzirisa chimiro chayo. Zviri nyore kushandisa.
