Nhazi nke ikpere
1. Dị ka radius nke curvature si dị, enwere ike kewaa ya na ogologo ogologoikiakana obere radius ikpere. Ogologo ikpere ụkwụ radius pụtara na radius nke curvature ya ruru okpukpu 1.5 n'obosara nke ọkpọkọ, ya bụ, R=1.5D. Oghere ukwu nke dị mkpụmkpụ pụtara na radius nke curvature ya na dayameta mpụta nke ọkpọkọ, ya bụ, R=D. N'ime usoro a, D bụ dayameta ikpere ụkwụ na R bụ radius nke curvature. Nkịtị a na-ejikarị eme ihe bụ 1.5D. Ọ bụrụ na egosighi ya na nkwekọrịta dị ka 1D ma ọ bụ 1.5D, ụkpụrụ ndị isi a na-ejikarị na China na-ebuli nhọrọ nke 1.5D bụ GB/T12459-2005, GB/T13401-2005, na GB/T10752-1995.
2. Dị ka usoro nhazi ahụ si dị, ọ na-abụkarị ikpere ụkwụ, square elbow, wdg.
Akụkụ dị mkpa nke ikpere
N'ozuzu, akụkụ ikpere ụkwụ, radius na-ehulata, dayameta, mgbidi mgbidi na ihe onwunwe nwere ike ikpebi naanị mgbe ịmara data ndị a.
Mgbakọ nke usoro iwu ịdị arọ nke ikpere
1. Gburugburu elbow: (mpụta dayameta – mgbidi ọkpụrụkpụ) * mgbidi ọkpụrụkpụ * ọnụọgụ * 1.57 * nominal dayameta * otutu ọnụọgụ: carbon ígwè: 0.02466
Igwe anaghị agba nchara: 0.02491Alloy 0.02483
90 ° ikiaka (mpụta dayameta - mgbidi ọkpụrụkpụ) * mgbidi ọkpụrụkpụ * ọnụọgụ (0.02466 maka carbon ígwè) * 1.57 * nominal dayameta * multiple / 1000 = theoretical arọ nke 90 ° elbow (kg)
2. Ụkwụ aka anọ:
1.57 * R * perimeta nke ọnụ ọnụ square * njupụta * ọkpụrụkpụ
Ngụkọta mpaghara ikiaka Ọ bụrụ na a na-agbakọ ịdị arọ, ị nwere ike iji ịdị arọ / njupụta / ọkpụrụkpụ iji gbakọọ mpaghara ahụ, ma ṅaa ntị na ịdị n'otu nke nkeji.
1. Gburugburu ikpere = 1.57 * R * caliber * 3.14;
2. Square elbow=1.57 * R * perimeter of square mouth
R na-anọchi anya radius na-ehulata, 90 Celsius ikikuaka usoro mgbako
