Imishini efanele ibalulekile ukukhiqiza intambo ye-PTFE nekhebula.Njengamanje, kunezinhlobo ezimbili ikakhulukazi: uhlobo lwemishini olushayelwa induku yesikulufu kanye nohlobo lwe-hydraulic oluqhutshwa ukucindezela kwe-hydraulic, lezi zinhlobo ezimbili ngayinye inezinzuzo kanye nokubi.
I-PTFE iyipulasitiki okunzima ukuyicubungula, ngakho-ke okokusebenza kusemqoka.Uma kufanele ukhiqize imigqa ye-MIL-grade PTFE extrusion, efana ne-RG178, RG179, RG316, RG142, G401, RG402, RG405, njll., okokusebenza okufanelekile kubalulekile.Njengamanje, kunezinhlobo ezimbili ngokuyinhloko emhlabeni: uhlobo lwemishini oluqhutshwa yinduku yesikulufu kanye nohlobo lwe-hydraulic olushayelwa umfutho we-hydraulic;izinhlobo ezimbili ze-PTFE pushers emakethe ngayinye inezinzuzo kanye nokubi:
(1) Ukuphusha ngesikulufu
Lokhu okwamanje kuvame kakhulu.Isikulufu siphinde sihlukaniswe ngesikulufu esislayidayo nesikulufu sebhola.Uma ufuna ukwenza intambo ye-coaxial, ngenxa yokuthi isikulufu esislayidayo sinobubi obubulalayo bokukhasa ngesivinini esiphansi, ukusunduza akuzinzile, futhi akunconyiwe.I-screw yebhola ayinayo le nkinga, kodwa ngenxa yokuthi indawo yokuxhumana nebhola inomkhawulo, kunenkinga enzima yokuphila ngaphansi kwengcindezi enkulu.Le ndlela ayifanele indlela yesilinganiso esikhulu sokucindezela, okungukuthi, lapho wenza ucingo, ikakhulukazi ubude obukhulu Umugqa omncane oboshiwe ungcono nakakhulu kuwo!Ngenxa yomkhawulo wobude be-screw nokunemba (kanye neminye imikhawulo efana nama-mandrels), ubude be-pusher abubude.Njengamanje, okuvamile kubonakala kungamamitha angu-1.5!Izinzuzo: Ngaphansi kwesimo sokugwema inkinga yokukhasa kanye nokuhuzuka komfutho ophezulu, isikulufu sinezinzuzo zokudluliswa okuzinzile kanye nenani eliphansi, okuyindlela eyinhloko yemishini ye-PTFE yasekhaya okwamanje.Isiqondiso sokuphusha sibheke phezulu kakhulu, kanti ezinye zenziwa ngokuvundlile.Ukuzifingqa ngomlomo othambile: [Ukukhiqizwa kwasekhaya kuwumshini, kuvuthiwe, kodwa ngenxa yokuthi kuvulekile futhi akulawuleki, izimiso kanye nesakhiwo sangempela semishini kudala kakhulu, ngokuyisisekelo iminyaka engama-30-40 Isakhiwo sangaphambilini esidala sinemibi amandla okusunduza aphansi (10-20T), ukusebenza kahle okuphansi, isivinini esinensayo, ubude obufushane bokukhiqiza, nokuguga kancane kancane kwenduku yesikulufu kuzoba nomthelela omkhulu ku-VSWR.Inzuzo ukuthi intengo iphansi.
(2) I-hydraulic push
Indlela emelwe i-JENNINGS e-United States isebenzisa ama-valve alinganayo alawulwa ngedijithali ukuze kuzuzwe ukulawula ukugeleza kwe-hydraulic okunembe ukuze kuzuzwe isivinini esizinzile sokuphusha.Ngenxa yokuthi kusetshenziswa indlela ye-hydraulic, amandla okuphusha makhulu kakhulu futhi angafinyelela ezingeni lamathani ayi-100.Ngale ndlela, i-compress ratio wire enkulu kulula ukuyifinyelela, futhi ngenxa yokuthi i-push enezingqimba isetshenziswa, isilinda singenziwa sibe side kakhulu (kuya kuma-intshi angu-108 = 2.7 amamitha), ngoba ingxenye ye-sintering isebenzisa i-front traction fumigation, ngakho-ke isivinini of extrusion futhi sintering ngokushesha!ukukhiqiza okuphezulu.Ukungalungi: Ngenxa yokuthi ukwenziwa kwasendaweni akufinyelelwanga, intengo yomshini iphezulu!Ngaphezu kwalokho, ukugcinwa kwengcindezi ye-hydraulic nakho kuyinkinga.Uma kungenziwanga kahle, kuzoba nenkinga yokuvuza kukawoyela.Ngithemba ukuthi abakhiqizi bemishini yasekhaya bazokwenza intuthuko kulokhu.Ukuzifingqa ngomlomo othambile: [okwangaphandle ngokuyisisekelo kuyi-hydraulic, ngoba kusetshenziswa ukulawulwa kwe-loop evaliwe, futhi amandla we-hydraulic makhulu (afinyelela ku-100T), ngakho-ke ukusebenza kahle kokukhiqiza kuphezulu nobude bokukhiqiza ubude (3-4 izikhathi), Futhi ikhwalithi izinzile (njengokuguquguquka kobubanzi bocingo, inkomba ye-VSWR, njll.) futhi ilawulwa ngokugcwele ikhompuyutha, okuyisinqumo esihle sokukhiqizwa kwesimanje!
(3) Idrayivu ye-electro-hydraulic
Lobu ubuchwepheshe obusezingeni eliphezulu kakhulu njengamanje, futhi buyindlela yokuthuthukiswa kwama-hydraulics.Iphinde ibe nezinzuzo ze-hydraulic thrust enkulu kanye nokudluliswa okuzinzile kwe-screw rod.Ayikaze isetshenziswe kubaphushi be-PTFE okwamanje, kodwa isiqale ukusetshenziswa kwezinye izinto zezempi ezisezingeni eliphezulu.
