Faodaidh tu fad gearraidh ceart an eas-tharraing stoc corda rubair obrachadh a-mach leis an àireamhair a leanas.Feuch an dearbhaich thu luachan ceart an trast-thomhas a-staigh (ID) agus crois-roinn ìomhaigh (CS) an toiseach agus an uairsin dèan àireamhachadh sìmplidh.
Mar eisimpleir:
A’ cleachdadh sreang trast-thomhas 10mm (CS), tha an neach-cleachdaidh ag iarraidh cearcall àbhaisteach a dhèanamh le trast-thomhas de 300 mm a-staigh.
Tha an àireamhachadh airson fad a’ chorda a ghearradh gus an o-ring a tha a dhìth mar a leanas:
300 (ID)+10 (CS) = 310
310 × 3.1415926 = 973.89mm
Feumar an corda a ghearradh gu fad 973.89 mm gus an o-ring a tha a dhìth a dhèanamh.
Tha meud corda àbhaisteach air a thomhas a rèir trast-thomhas ìomhaigh.Tha an clàr seo a’ sealltainn an dà chuid meudan ìmpireil agus meatrach.Bidh an clàr cuideachd a’ taisbeanadh fulangas corda o-ring, gus an urrainn dhut obrachadh a-mach gu ceart an urrainn don chorda a bhith freagarrach airson an tagradh mionaideach agad.Am measg nam meudan sin, tha meud an òirleach beagan eadar-dhealaichte bho mheud AS568 o-ring, fhad ‘s a tha am meud meatrach stèidhichte sa mhòr-chuid air margaidh china agus cuid de mhargaidhean thall thairis.Gu bunaiteach, is urrainn dhuinn na meudan sin de chorda a dhèanamh aig àrd chàileachd, prìs farpaiseach, agus lìbhrigeadh gu math luath.Mura h-eil cuid de mheud air a liostadh sa chlàr, feumaidh tu fios a chuir thugainn gus beachdachadh air a’ chorda àbhaisteach agad.Dh’ fhaodadh pacadh a’ chorda rubair a bhith gu math sìmplidh no ceangailte ann an rolair.Feuch an òrdaich thu a rèir na fìor fheumalachdan agad.
