IZICI EZISEKUKHETHWENI KWAMASHUBHU ASHINYA OKUSHISAYO?

Ububanzi obujwayelekile bepayipi elincibilika ngokushisa:

Isihluthulelo seshubhu yokunciphisa ukushisa kufanele sisetshenziswe njengomkhiqizo wokuvimbela ikhebula. Ingxenye evundlile yeshubhu yokunciphisa ukushisa iyisimo seshubhu esiyisilinda, ngakho-ke ububanzi obujwayelekile bungusayizi wobubanzi bangaphakathi bobukhulu bodonga. Le pharamitha eyinhloko ihlobene nokuthi iyahambisana yini nekhebula lokuvikela ukuphepha. Uma ububanzi obujwayelekile buncane kakhulu, abukwazi ukufakwa eshubhuni, futhi uma bukhulu kakhulu, abukwazi ukuvalwa kahle. Ukukhetha kumele kwenziwe ngokwezincazelo zomkhiqizo. Uphawu Φ lubonisa ububanzi beshubhu yokunciphisa ukushisa, kanti ukulungiselelwa okuzenzakalelayo kungu-mm.

Amapayipi okunciphisa ukushisa anodonga oluncane:

Ubukhulu bodonga lweshubhu elincibilika ngokushisa busho ubukhulu bezinto zokufaka amapayipi. Ubukhulu bezinto zokufaka amapayipi bulimaza usayizi wokuvikelwa kokuphepha kwesendlalelo sokuvikela. Ngakho-ke, uma ubukhulu beshubhu elincibilika ngokushisa buphakeme, kulapho ikhono lokuvikela lokuphepha liba ngcono khona. Ngaphezu kwalokho, uma ubukhulu buphakeme, kulapho ukuthuthukisa ikhono lomsebenzi wokuvikela ukuphepha walo mkhiqizo kungathuthukisa amandla okucindezela alo mkhiqizo, kodwa uma ubukhulu buphakeme, kuzoba nzima kakhulu. Ngokuvamile, amashubhu ancibilika ngokushisa anobukhulu nobukhulu obuphezulu asetshenziswa emigwaqweni nasemikhiqizweni engeyona inkimbinkimbi.

Ngokuvamile, amashubhu ancibilika ngokushisa anobukhulu nobukhulu obuphezulu asetshenziswa emigwaqweni nasemikhiqizweni engeyona inkimbinkimbi.

Izinga lokuncipha kwepayipi elincibilika ngokushisa:

Izinga lokuncipha libhekisela esilinganisweni sobubanzi obujwayelekile beshubhu elincibilikisa ukushisa ngaphambi kokuncipha kuya kububanzi obujwayelekile ngemva kokuncipha. Izinga lokuncipha libonisa ubukhulu bomthamo wokuncipha weshubhu elincibilikisa ukushisa. Uma izinga lokuncipha liphezulu, ishubhu elincibilikisa ukushisa liba lincane uma livaliwe ngokuphelele. Izilinganiso ezivamile zokuncipha kwamashubhu ancibilikisa ukushisa ziyi-2:1, 3:1, kanye no-4:1. Ukukhetha kwangempela kufanele kucatshangelwe ngokwezidingo zomkhiqizo.

Ukushisa kwe-shrink tube lokushisa ukuncipha:

Ukuncipha kweshubhu elincibilikisa ukushisa kuyinqubo ephelele yombala we-gradient, ngakho-ke izinga lokushisa lokuncipha kweshubhu elincibilikisa ukushisa lihlukaniswe izinga lokushisa lokuqala lokuncipha kanye nezinga lokushisa lokugcina lokuncipha. Izinga lokushisa lokuncipha lishiswa kuze kube sekuqaleni kweshubhu elincibilikisa ukushisa. Ngokuphathelene nezinga lokushisa ngesikhathi sokuncipha, imikhono evamile yabantu yokuncipha kokushisa ye-PE inokushisa kokuncipha okungu-84°C ekuqaleni, okungukuthi, inokusabela kokuncipha ekuqaleni. Izinga lokushisa lokugcina lokuncipha izinga lokushisa elingenza ishubhu elincibilikisa ukushisa lidlule izinga lokushisa eliphelele lokuncipha. Ishubhu elincibilikisa ukushisa lizoqala ukuncipha uma lidlula izinga lokushisa lokuqala lokuncipha.

Izinga lokushisa lokusebenza kwe-tubing yokunciphisa ukushisa:

Izinga lokushisa lokusebenza lomkhiqizo weshubhu elincibilika ngokushisa kumele linake izinga lokushisa lokusebenza elijwayelekile lokusetshenziswa kweshubhu elincibilika ngokushisa kuma-degrees angu-55 kuya ku-125. Ngemva kolwazi lwedatha, impilo yesevisi yeshubhu elincibilika ngokushisa kanye nezici zokuvikela ukuphepha kwesendlalelo sokufaka umswakama akunakuqinisekiswa endaweni yemvelo ngemva kolwazi lwedatha.

Imithunzi Yeshubhu Yokushisa Encishisiwe:

Umbala wepayipi elincipha ngokushisa akudingeki ube mkhulu. Amakhasimende kufanele akhethe umbala afuna ukuwusebenzisa kuphela. Ngokuvamile, abakhiqizi bamapayipi ancipha ngokushisa banemibala yokukhanya efana nobisi, empunga-mnyama, ebomvu ekhanyayo, ephuzi ekhanyayo, kanye neluhlaza okwesibhakabhaka okumnyama ukukhetha. Uma ungumthengi ongenasabelomali esanele, kungcono ukhethe okumpunga nokumnyama.
