Siab Plate Compatibility: Hom xaiv thiab kev teeb tsa raug
Vim li cas thiaj li tiv thaiv -nplua plav qauv clamps nyiam rau cov kab nkhaus?
Thaum cov tsheb ciav hlau hla dhau cov kab nkhaus, lateral zog tshaj 8kN raug tsim. Ordinary smooth clamps muaj kev sib txhuam coefficient ntawm tsuas yog 0.3 thiab yooj yim rau zawv zawg, cuam tshuam kev ruaj ntseg. Qhov nto roughness ntawm anti- plam patterned clamps yog Ra 3.2-6.3μm, thiab kev sib txhuam coefficient yog nce mus rau 0.45, uas muaj peev xwm tiv thaiv lateral rog. Tus qauv tsim ua rau kom qhov chaw sib cuag ntawm lub clamp thiab txoj kev tsheb ciav hlau, disperses siab, txo cov hnav hauv zos, thiab ncua kev pab cuam lub neej. Kev taw qhia kev teeb tsa ntawm kev tiv thaiv-slip clamps muaj cov cai nruj; tus qauv nto yuav tsum fim txoj kev tsheb ciav hlau kom ntseeg tau tias muaj kev cuam tshuam los tiv thaiv- plam, thiab rov qab kev teeb tsa yuav txo qis kev ua haujlwm tsis zoo. Ntawm cov kab me me uas muaj lub vojvoog tsawg dua 600m, cov khoom siv los tiv thaiv plam yog cov khoom siv tseem ceeb, uas tuaj yeem tswj cov kev hloov pauv sab nraud hauv 0.2 hli, zoo dua li 0.5 hli ntawm cov clamps du.
Dab tsi yog qhov yuav tsum tau rau lub installation txoj hauj lwm sib txawv ntawm clamps?
Qhov ntev ntawm txoj hauj lwm sib txawv ntawm lub clamp yuav tsum tau tswj nyob rau hauv ± 2 hli kom paub meej qhov tseeb txheeb ze txoj hauj lwm nrog txoj kev tsheb ciav hlau thiab ncoo, tsis txhob cuam tshuam cov nyhuv clamping. Qhov sib txawv ntawm sab nraud yuav tsum tsis pub tshaj ± 1mm los tiv thaiv lub clamp ntawm leaning mus rau ib sab, ua rau lub zog tsis sib npaug ntawm txoj kev tsheb ciav hlau thiab ua rau kev khiav tawm. Qhov sib txawv ntawm lub clamp thiab cov tsheb ciav hlau yuav tsum tsis sib xws, nrog rau ib qho - sab qhov sib txawv tsis tshaj 0.3mm thiab tag nrho qhov sib txawv ntawm ob sab tsis tshaj 0.5mm los xyuas kom haum zoo. Thaum txhim kho ntau lub clamps, qhov sib txawv ntawm qhov sib txawv yuav tsum tsis pub tshaj ± 3mm kom tswj tau qhov kev sib haum xeeb thiab xyuas kom muaj kev sib npaug. Tom qab kev teeb tsa, siv ib theem txhawm rau txheeb xyuas qhov flatness ntawm lub clamp, nrog qhov sib txawv ntawm tsis pub tshaj 0.5mm / m kom tsis txhob muaj kev ntxhov siab vim qhov tsis sib xws.
Dab tsi yog cov txheej txheem sib txawv ntawm insulating clamps thiab zoo tib yam clamps?
Insulating clamps muaj cov iav fiber ntau lossis epoxy resin rwb thaiv tsev txheej nrog lub thickness ntawm ntau dua los yog sib npaug rau 2 hli thiab rwb thaiv tsev tsis kam ntawm ntau dua los yog sib npaug rau 10⁹Ω, uas tuaj yeem tiv thaiv tam sim no. Ordinary clamps yog cov qauv hlau tsis muaj cov txheej txheem rwb thaiv tsev, nrog cov khoom siv hluav taws xob zoo, tsim nyog rau cov kab uas tsis muaj rwb thaiv tsev. Insulating clamps yog nruab nrog insulating washers nyob ib ncig ntawm lub ntsia liaj qhov rooj qhov kom tsis txhob conduction ntawm lub ntsia liaj qhov rooj thiab cov hlau ib feem ntawm lub clamp, kom ntseeg tau tias rwb thaiv tsev nyhuv. Cov khoom siv ntawm cov clamps zoo tib yam feem ntau yog Q235 steel, thaum insulating clamps txais cov qauv sib xyaw ntawm siab - zog engineering yas thiab hlau, sib txuas lub zog thiab rwb thaiv tsev. Insulating clamps feem ntau yog daj lossis ntsuab rau kev txheeb xyuas yooj yim, thaum cov clamps zoo tib yam feem ntau yog xim dub lossis grey nrog cov tsos yooj yim.
Dab tsi yog qhov tsim nyog tsim lub zog rau clamps ntawm hnyav -cov kab?
Lub zog tensile ntawm clamps rau hnyav- cov kab tsheb yuav tsum tsis pub tsawg dua 345MPa, thiab lub zog compressive Ntau dua lossis sib npaug li 500MPa, uas tuaj yeem tiv taus siab -frequency impact loads of 27t qag load. Lub thickness ntawm lub clamp yog 1-2 hli tuab dua li ntawm cov pa kab, thiab cov kev ntxhov siab tseem ceeb-cov kabmob yog tsim los nrog kev txhawb nqa tav los txhim kho kev tiv thaiv -deformation peev xwm. Cov khoom siv yog siab -lub zog alloy steel, uas tau dhau los ua kev kho cua sov, thiab lub hardness yog tswj ntawm 200-250HB, muaj zog txaus thiab zoo toughness. Lub qhov taub lub qhov taub ntawm lub clamp yog 1-2mm loj dua li ntawm cov clamps zoo tib yam, yoog rau cov ntsia hlau muaj zog thiab txhim kho kev sib txuas kev ntseeg tau. Hnyav-haul clamps yuav tsum dhau 1 lab qhov kev sim qaug zog yam tsis muaj qhov tshwm sim tsis ua haujlwm xws li tawg thiab deformation kom ruaj khov rau kev pabcuam ntev.
Dab tsi yog cov qauv tswj rau kev zawm torque ntawm clamps?
Lub zog torque ntawm clamps rau cov pa kab feem ntau yog 350-400N·m kom ntseeg tau tias muaj zog clamping txaus yam tsis muaj kev puas tsuaj rau lub clamp lossis kev tsheb nqaj hlau. High- txoj kev tsheb ciav hlau ceev muaj qhov yuav tsum tau ua kom du, thiab lub zog torque yog tswj ntawm 400-450N·m kom ntseeg tau tias kev sib txuas ruaj khov yam tsis muaj kev cuam tshuam rau txoj kev elasticity. Clamps rau hnyav- cov kab tsheb yuav tsum tau nqa ntau dua, yog li lub zog torque tau nce mus rau 500-550N·m, thiab lub zog tawg yuav tsum tsis pub tshaj 8% hauv ib hlis. Lub torque ciaj ntswj yuav tsum tau siv rau zawm, zawm nyob rau hauv ob theem: pre-tightening mus rau 50% ntawm lub torque thawj zaug, thiab zawm mus rau tus qauv tus nqi rau lub thib ob lub sij hawm los xyuas kom meej lub torque uniform. Lub torque ntawm clamps ntawm cov khoom sib txawv me ntsis txawv; lub torque ntawm yas composite clamps yuav tsum tau txo los ntawm 10% kom tsis txhob clamp cracking tshwm sim los ntawm over-tightening.
