Tightening da hakkin lokaci

Karfin juyi ne ake kira rotational karfi, watau tightening da kwayoyi. rotational karfi aka auna a Newtons da mita 1 - nm. Domin flanges, wanda ake hawa aron kusa karfin juyi samar da wani axial load a kan su. A axial kaya (axial) - a karfi wanda abubuwa a gefen da tace kashi. Yana iya kai ga nakasawa daga cikin kashi ko warwarewarsu dakile. A lokacin tightening na kusoshi na spring sakamako ne kiyaye.

Lokacin da tightening da goro aron kusa tashin hankali ya auku, da kwanciya da load ƙaruwa. Axial kaya ne mai kai tsaye aiki na gogayya karfi. Idan ya canjãwa, to, lalle akwai wani canji a cikin kaya samu da rufi. Don karfin juyi da kusoshi ya faru a kan dukan dokokin, kana bukatar ka sa mai da su tare da kwayoyi da kuma washers. Dairy kaya tsoma kuma shi ne wani muhimmin fifiko daga cikin taro flanges. A karfin juyi ne a haɗe musamman karfin juyi tsananin baƙin ciki. Duk da haka, akwai fiye da m hanyoyi da shafi karfin juyi na kusoshi da karshen sakamakon.

Abin da ya kamata ya zama da karfi a kan a haɗa kusoshi?

A aron kusa compresses juna flanges. A tightening karfin juyi na kusoshi dole ne a tsaurara don ci gaba da kaya a kan GASKET da kuma yawan zafin jiki saukad, da kuma matsa lamba bambanci a cikin al'ada tsari, da kuma lokacin da tsarin da aka matsa.

A wasu hanyar sadarwa mukaddashin karin load. Sa'an nan da aron kusa connection ne iya daidaita a kowane lokaci da kuma har yanzu ya kasance m.

The yawan amfanin ƙasa ƙarfi daga cikin kayan daga wanda kerarre aron kusa ne load, kyale shi mai shimfiɗa ta zuwa iyakar halatta tsawon, bayan wanda ta kõma, zuwa ga ainihin jihar. Mikewa iya zama a wuce haddi na halatta matakan amfanin ƙasa. A wannan yanayin, a lokacin da load an cire, da aron kusa hidima a matsayin irin "spring samu".

Lokacin da aron kusa tightening karfi an wuce, mikewa ya auku canja yawan amfanin ƙasa danniya, wadda take kaiwa zuwa wani kaya raguwa. Lokacin da tightening da sukurori bukatar ka mai da hankali ga ba hauling faru da cewa daidai zai kai ga spoilage. Tightening lokacin - a laborious tsari, dole ne mu tabbatar da cewa duka kaya a kan kushin ne a hankali raunana, a kan sikelin na 40-100% yawan amfanin ƙasa ƙarfi. Shi ne kuma dole don tabbatar da cewa bai canja ba da mutuncin gaskets, flanges. Awon karfin wuta wadda aka yarda a yi amfani da surface na GASKET kamata taba wuce wata qaddara darajar. A dace zabi na aron ne mai zama dole yanayin ga aikin flange connection.

Yadda za a bi da tightness?

Biyu yanayi da cewa dole ne a hadu:

1. } O} arin, jajirce da nufin latsa GASKET da kuma rike da shi a wurin. Load kusoshi dole ne irin wannan cewa GASKET matse fadin surface na flange.
2. A karfi wanda wajibi ne don:

• Don wuce da hydrostatic load.
• A GASKET aka guga man da kuma gudanar da tukwãne, don haka da cewa matsin lamba bai samu ciki.
• Ajiye load a kan tsiri bayan da hydrostatic load.
