Hauv kev lag luam cov kav dej, kev xaiv ntawm txoj kev sib txuas ncaj qha txiav txim siab txog kev nyab xeeb, kev ntseeg tau thiab kev saib xyuas kev ua haujlwm ntawm qhov system. Lub qhov (socket) pob qij txha thiab vuam pob qij txha, raws li ob lub ntsiab kev sib txuas thev naus laus zis, tau siv dav hauv kev lag luam xws li chemical engineering, pharmaceuticals, semiconductors, thiab lub zog. Kab lus no yuav ua kom muaj kev sib piv los ntawm qhov ntev xws li kev tsim qauv, kev sib txuas hauv paus ntsiab lus, cov yam ntxwv ntawm kev ua haujlwm, daim ntawv thov scenarios thiab cov nqi kho mob, muab cov ntaub ntawv tshawb fawb txog engineering.
I. Tus Qauv Tsim: Kev faib nruab nrab ntawm Modularization thiab kev koom ua ke
1.1 Modular Architecture ntawm Coupling Head
Lub taub hau coupling txais yuav peb tus qauv tsim, suav nrog lub taub hau lub cev, lub tes tsho txuas, thiab cov txiv ntoo. Lub taub hau lub cev ua haujlwm tseem ceeb hauv kev sib txuas, nrog cov qauv tsim los ntawm conical zawj ntawm nws cov phab ntsa sab hauv; lub tes tsho coupling yog ib lub nplhaib - zoo li tus hlau daim nrog serrated puab npoo; thiab cov txiv ntseej txuas nrog lub taub hau lub cev los ntawm threads. Noj 316L stainless hlau coupling taub hau ua piv txwv, kev kam rau siab ntawm sab hauv txoj kab uas hla ntawm lub tes tsho coupling mus rau sab nraud ntawm cov kav dej yuav tsum tau tswj nyob rau hauv ± 0.05mm los xyuas kom meej qhov tsim ntawm ob - lub nplhaib foob thaum lub sij hawm kev koom tes.
Qhov no modular tsim muab lub taub hau coupling peb zoo:
Ua ntej, nws tuaj yeem hloov kho rau cov khoom sib txawv ntawm cov kav dej, xws li PFA, PTFE, thiab stainless hlau;
Thib ob, txoj kab uas hla ntawm cov yeeb nkab tuaj yeem hloov pauv los ntawm kev hloov cov ntsiab lus haum. Piv txwv li, nws tuaj yeem hloov tau los ntawm DN15 rau DN20.
Thib peb, lub cev haum tuaj yeem tsim los ntawm ntau hom xws li ncaj- dhau los, peb- txoj kev, thiab lub luj tshib, kom ua tau raws li qhov yuav tsum tau ua ntawm cov kav dej sib txuas.
1.2 Fusion Integrated Structure ntawm Welded Joints
Lub fusion integrated qauv ntawm welded pob qij txha ua tiav atomic- qib kev sib txuas ntawm cov raj xa dej thiab qhov sib koom ua ke los ntawm siab - kub melting. Siv cov PFA welded sib koom ua piv txwv, cov txheej txheem vuam yuav tsum ua kom sov lub raj xa dej kawg lub ntsej muag thiab qhov sib koom ua ke mus rau 327℃(lub melting point ntawm PFA), tswj qhov kub ntawm 0.2 MPa siab rau 15 vib nas this, kom cov ntaub ntawv muaj peev xwm fuse tag nrho. Ib txoj kab 0.1-0.3mm fusion yog tsim nyob rau hauv qhov chaw vuam, thiab nws cov microstructure nthuav tawm cov yam ntxwv cam khwb cia, nrog rau qhov ntau thiab tsawg ntawm cov nplej yog 30% -50% zoo dua li cov khoom siv hauv paus, ua kom muaj zog sib koom ua ke.
Cov qauv kev sib xyaw ua ke coj ob qhov txiaj ntsig zoo:
Ua ntej, lub zog tensile ntawm qhov sib koom ua ke tuaj yeem ncav cuag ntau dua 95% ntawm cov khoom siv hauv paus, deb tshaj li 70% -80% ntawm qhov sib koom ua ke;
Qhov thib ob, qhov kev sib txuas fusion tshem tawm cov xov sib txawv, thiab tseem tuaj yeem tswj tsis tau xoom xau nyob rau hauv siab -cov xwm txheej siab (xws li tshaj 16 MPa). Qhov tseeb ntsuas cov ntaub ntawv los ntawm ib lub tuam txhab semiconductor qhia tau hais tias PFA welded sib koom ua haujlwm tsis tu ncua ntawm 25 MPa siab rau 2000 teev, nrog rau tus nqi qis dua 1 × 10⁻⁹ Pa·m³ / s.
II. Txoj Cai Kev Sib Txuas: Qhov txawv ntawm Mechanical Interlock thiab Metallurgical Bonding
2.1 Mechanical Sealing Mechanism ntawm lub tes tsho Joint
Cov txheej txheem sib khi ntawm lub tes tsho sib koom ua ke muaj peb theem: theem ua ntej- zawm, theem kev sib koom ua ke, thiab theem sib khi. Thaum cov txiv ntseej nruj, lub tes tsho ua ntej dhau los ua elastic deformation, thiab nws cov ntug sab hauv tsim kev sib cuag nrog cov phab ntsa sab nrauv ntawm cov kav dej; Raws li lub zog torque nce (feem ntau ncav cuag 30-50 N·m), sab hauv ntawm lub tes tsho txiav rau hauv cov kav dej los ntawm 0.1-0.2 hli, ua tiav kev ntsuas qhov ntsuas; Thaum kawg, sab nrauv conical ntawm lub tes tsho nruj nruj rau sab hauv conical nto ntawm qhov sib koom ua ke, ua kom muaj kev sib cuag ntawm 50-80 MPa ntawm qhov chaw sib cuag, ua tiav ob lub sealing.
Txoj kev sib txuas ntawm cov tshuab no muaj ob qhov kev pheej hmoo:
Ua ntej, kev vibration tej zaum yuav ua rau lub tes tsho xoob. Cov ntaub ntawv tshawb fawb ntawm cov kav dej xa hluav taws xob qhia tau hais tias nyob rau hauv ib puag ncig kev co nrog zaus ntawm 10 Hz thiab amplitude ntawm 2 mm, lub tes tsho sib koom yuav tsum tau rov ua dua - nruj txhua 3 lub hlis;
Qhov thib ob, cov khoom hauv nruab nrab tuaj yeem hnav lub tsho sab hauv ntawm lub tes tsho. Daim ntawv tshaj tawm los ntawm cov tuam txhab tshuaj tshuaj qhia tau hais tias qhov nruab nrab uas muaj SiO₂ hais yuav ua rau lub tsho luv luv ntawm 60%.
2.2 Cov txheej txheem Metallurgical Fusion ntawm Vuam Joints
Kev tsim cov vuam sib koom ua ke muaj plaub theem: kev ua kom sov, melting, diffusion, thiab solidification. Siv TIG welding (Tungsten Inert Gas Shielded Vuam) ua piv txwv, qhov kub ntawm arc tuaj yeem ncav cuag 6000-8000 degree, ua rau cov khoom PFA ncav cuag lub xeev molten hauv 0.1 vib nas this. Cov saw molecular ntu nyob rau hauv lub pas dej molten ua tiav rov kho dua los ntawm cov saw ntu diffusion, tsim ib homogeneous qauv. Tom qab welding, annealing kev kho mob (tuav ntawm 280℃rau 2 teev) yog yuav tsum tau tshem tawm cov residual kev nyuaj siab, txo qhov sib koom hardness los ntawm 15% -20% thiab pab txhawb kev tiv thaiv kev ntxhov siab tawg.
Lub metallurgical bonding coj peb qhov zoo ntawm kev ua tau zoo:
Ua ntej, nyob rau hauv qhov kub ntawm -80℃mus rau 260 degree, linear expansion coefficient ntawm vuam sib koom ua ke ntawm cov khoom siv hauv paus rau 98%;
Qhov thib ob, nws kam rau ua kom muaj zog corrosive media xws li hydrochloric acid thiab sulfuric acid yog nce los ntawm 3-5 zaug;
Thib peb, nyob rau hauv lub tshuab nqus tsev (siab tshaj 10⁻³ Pa), lub helium huab hwm coj spectrometry leak nrhiav tus nqi ntawm cov vuam sib txuas tuaj yeem tswj tau qis dua 1 × 10⁻¹² Pa·m³ / s.
