Anti-loosening tech rau sustainable machinery? 

Koj hnov ​​los tiv thaiv xoom thiab tam sim ntawd xav tias locknuts lossis threadlocker, txoj cai? Qhov ntawd yog qhov cuab yeej cuab tam. Kev sib tham tiag tiag tsis yog tsuas yog txwv tsis pub lub bolt ntawm tig; Nws yog hais txog kev tswj cov clamp load lwj hauv vibrating, thermal-cycling ib puag ncig tshaj 15-xyoo tshuab lifespan. Sustainability ntawm no tsis yog ib tug buzzword - nws yog hais txog kev tiv thaiv tsis ua hauj lwm ntxov ntxov, zam lub zog thiab cov ntaub ntawv pov tseg ntawm tas li re-torquing los yog hloov, thiab frankly, nres lub cascade ntawm downtime. Feem ntau cov kev sib tham tsis nco qab qhov tseeb tias lub fastener tsuas yog ib feem ntawm kev sib koom ua ke. Yog tias tus qauv tsim lossis kev teeb tsa tsis raug, txawm tias cov thev naus laus zis zoo tshaj plaws yuav tsis txuag nws.

Cov teeb meem tseem ceeb: Nws tsis yog hais txog nruj, Nws yog hais txog kev sib haum xeeb

Thaum ntxov ntawm kuv lub sijhawm ntawm kev saib xyuas cov tshuab hnyav, peb tau ua raws li kev vibration-induced loosening los ntawm tsuas yog cranking bolts tighter. Ib qho yuam kev classic. Tshaj-torquing stretches lub ntsia liaj qhov rooj, muaj peev xwm ua rau muaj kev ntxhov siab corrosion cracking los yog tsuas yog nyiag nws ntawm nws elasticity - nws muaj peev xwm ua tau zoo li lub caij nplooj ntoos hlav thiab tuav lub zog clamp. Lub hom phiaj yog qhov zoo ib yam, txhim khu kev qha clamp load uas tawm tsam tus kheej-loosing. Kuv nco qab lub conveyor tsav ncej uas tshee nws tus kheej sib nrug txhua rau lub hlis. Peb sim serrated flange ceev, uas ua hauj lwm ... txog yim lub hlis. Qhov teeb meem yog cov pleev xim rau, tsis sib xws mating nto tsim tsis sib xws siab faib. Lub txiv ntoo tsis poob; kev sib koom tsim tau ua.

Qhov ntawd yog qhov chaw ua haujlwm tiag tiag pib. Koj yuav tsum tau saib tag nrho cov kev sib koom ua ke: lub fastener cov cuab yeej chav kawm, qhov flange flatness, qhov tawv ntawm cov khoom clamped. Lub tshuab ntxhua khaub ncaws tawv nyob rau hauv tus qauv txiv ntoo ntawm lub vaj tsev muag muag tsuas yog thov kom embedding thiab load poob. Peb kawm los qhia kom meej cov duab kos, xam cov load-deformation nkhaus. Nws zoo li kev kawm, tab sis nws yog qhov sib txawv ntawm kev sib koom ua ke uas muaj sia nyob thiab ib qho uas dhau los ua mob taub hau.

Qhov no yog qhov chaw manufacturers uas tau txais qhov system mus kom ze sawv tawm. Kuv tab tom nrhiav rau cov neeg muag khoom uas tuaj yeem tham txog ntau dua li DIN cov qauv, thiab tuaj hla HANDAN ZITAI FREWER RAUG UA MOV., Ltd.. Lawv qhov chaw nyob hauv Yongnian, lub hauv paus tsim khoom loj, txhais tau tias lawv tau pom tag nrho. Dab tsi yog qhov muaj txiaj ntsig tsis yog lawv cov ntawv teev npe xwb, tab sis lawv cov ntawv sau engineering ntawm daim ntawv thov scenarios. Nws yog ib yam uas yuav muag ib prevailing torque txiv ntoo; Nws yog lwm qhov los qhia thaum siv cov nylon ntxig piv rau cov hlau-alloy deformed xov raws li qhov kub thiab txias thiab kev xav tau rov siv dua. Qhov kev ua tau zoo, kev paub los ntawm kev nkag siab yog kub.

Tshaj li Tshuaj: Mechanical Locking nyob rau hauv hnyav ib puag ncig

Threadlockers muaj lawv qhov chaw - qis rau nruab nrab lub luag haujlwm, kaw ib puag ncig. Tab sis ntawm lub mining excavator los yog ntug hiav txwv cua turbine ntauwd flange? Tsis nco qab lawm. UV, kub heev, roj, thiab sheer vibration yuav zom cov nplaum. Rau sustainability, koj xav tau ib tug mechanical, reusable daws. Peb tau sim ntau yam kev xaiv ntawm lub tshuab hluav taws xob diesel.

Sab saum toj-xauv txiv ntoo nrog ib qho deformed xov seem ua haujlwm zoo rau cov ntsiab lus nkag tau tab sis tau mob hauv qhov chaw nruj. Peb tau txais txiaj ntsig zoo mus ntev nrog wedge-locking washer systems. Lub hauv paus ntsiab lus yog yooj yim: lub kaum sab xis cams ntawm lub tshuab ntxhua khaub ncaws khawb hauv, tsim kom muaj zog tiv thaiv kev sib hloov. Qhov tseem ceeb, txawm li cas los xij, yog kev teeb tsa kom raug - lawv tsuas yog ua haujlwm hauv qhov kev xav tau. Kuv tau pom cov neeg ua haujlwm nplawm lawv rov qab, ua rau lawv tsis muaj txiaj ntsig. Kev cob qhia yog ib feem ntawm tech.

Tom qab ntawd muaj rab phom loj: nro tswj bolt (TC bolt) tshuab nrog hardened washers. Cov no yog qhov zoo heev rau kev sib txuas flange loj, xws li ntawm cov qauv hlau lossis cua turbine hubs. Koj siv ib tug shear wrench uas snaps lub spline kawg ntawm ib tug meej nro. Nws muab rau koj pom, mus / tsis mus pov thawj ntawm kev teeb tsa raug. Lub kaum sab xis ntawm kev ruaj ntseg yog qhov tseeb: kev sib koom ua ke kom raug pom pom qhov sib txheeb me me, txo qis fretting hnav thiab qaug zog. Qhov downside? Cov cuab yeej tshwj xeeb thiab cov nqi tsev siab dua. Koj yuav tsum ua pov thawj nws los ntawm kev siv lub neej, tsis yog siv nyiaj ua ntej.

Daim ntawv ceeb toom ceev ntawm cov teeb meem dawb-Spinning

Puas tau muaj txiv ntseej uas tig dawb tab sis yeej tsis tau nruj? Nws feem ntau raug tso tseg raws li txoj xov tsis zoo. Qee zaum nws yog. Tab sis feem ntau, nws yog bolt xov pitch deformation los ntawm yav dhau los over-torquing, los yog cov khib nyiab ntim rau hauv cov txiv ntseej lub xauv feature. Nws yog ib qho me me, ntxhov siab nthuav dav uas nres tag nrho cov kab sib dhos. Kev kho tsis yog ib lub txiv ntoo tshiab xwb; nws yog tshuaj xyuas cov txiv neej xov nrog lub ntsuas thiab ntxuav cov mating nto. Pom tseeb, tab sis niaj hnub overlooked nyob rau hauv maj kom tau txais yam uas khiav.

Khoom & Txheej Dance

Sustainability kuj txhais tau hais tias kev sib ntaus sib tua corrosion, uas noj cov khoom thiab ua kom muaj kev sib txhuam, hloov cov kev sib raug zoo torque-tension. Ib qho galvanically corroded sib koom ua ke seizes lossis poob clamp load. Peb standardized ntawm kub-dip galvanized los yog dacromet-coated fasteners rau sab nrauv, high-humidity daim ntaub ntawv. Tab sis ntawm no yog qhov ntes: coatings ntxiv thickness. Yog tias koj tsis suav rau qhov ntawd hauv koj qhov torque specs, koj nyob qis qis. Lub 15-micron zinc flake txheej tuaj yeem hloov pauv qhov sib txhuam coefficient. Peb tau kawm nug cov neeg muag khoom rau cov ntaub ntawv torque-tension rau lawv cov khoom tshwj xeeb coated, tsis yog cov khoom siv hauv paus xwb. Qee tus, zoo li Zitai, muab cov kab kos no yooj yim, uas qhia tias lawv nkag siab txog daim ntawv thov, tsis yog kev tsim khoom xwb.

Kev xaiv cov khoom siv yog lwm qib. Tsiv los ntawm tus qauv 8.8 qib mus rau 10.9 lossis txawm tias 12.9 tso cai rau lub taub me me rau tib lub thauj khoom, txuag qhov hnyav thiab cov khoom siv. Tab sis qib siab dua txhais tau tias muaj kev cuam tshuam ntau dua rau hydrogen embrittlement yog tias tsis ua tiav. Koj tab tom ua lag luam ib qho kev pheej hmoo rau lwm tus. Peb muaj ib pawg ntawm cov bolts qib siab tsis ua rau muaj kev puas tsuaj loj ntawm cov xovxwm haum - tig tawm cov txheej txheem plating qhia hydrogen, thiab lawv tsis tau ci kom zoo rau kev tawm. Tus neeg muag khoom tau liam peb qhov kev teeb tsa torque. Nws yog ib zaj lus qhia tsis txaus ntseeg hauv kev soj ntsuam tag nrho cov saw hlau cov txheej txheem tswj.

Installation: Qhov twg Qhov Zoo Tshaj Tech Mus Tuag

Qhov no yog lub pas dej loj ntawm txoj kev xav thiab kev xyaum. Koj tuaj yeem hais qhia qhov zoo tshaj plaws Nord-Lock ntxhua khaub ncaws los yog cov khoom siv hluav taws xob zoo tshaj plaws. Yog hais tias tus txiv leej tub nrog qhov cuam tshuam wrench tsis paub cov txheej txheem, nws tsis muaj nqis. Calibrated torque wrenches yog ib qho yuav tsum tau, tab sis lawv tau kuaj ntau npaum li cas? Peb tau siv lub kaw lus uas cov pob qij txha tseem ceeb (xav tias gearbox mounts, structural links) yuav tsum tau kos npe-tawm torque cav nrog cov cuab yeej ID. Nws xav tias bureaucratic, tab sis nws txiav cov kev ua tsis tiav los ntawm tej zaum 70%.

Qhov sib lawv liag tseem ceeb heev, tshwj xeeb tshaj yog nyob rau hauv ntau lub bolt flanges. Cov qauv lub hnub qub classic tau qhia rau qhov laj thawj - nws ua kom txawm tias gasket lossis nto compression. Kuv tau saib cov neeg kho tshuab caij nyoog tsis quav ntsej qhov no ntawm hydraulic manifold, ua rau muaj qhov tsis tu ncua uas lawv tau caum rau lub lis piam los ntawm nruj ib lub ntsia liaj qhov rooj ntau zaus. Lawv warped lub flange. Qee lub sij hawm qhov kev siv thev naus laus zis los tiv thaiv kom ruaj khov tshaj plaws yog ib daim ntawv: qhia meej, qhia txog kev ua haujlwm.

Kuj tseem muaj kev xav ntawm tib neeg. Ib tus kws kho mob uas muaj kev paub dhau los tuaj yeem kuaj pom tus ntoo khaub lig lossis lub yielding ntsia liaj qhov rooj los ntawm kev hloov hauv kev tiv thaiv thaum lub sij hawm nruj, ib yam dab tsi lag ntseg torque ciaj ntswj tsuas yog blasts los ntawm. Qhov kev tawm tswv yim tactile ntawd yog txheej txheem tswj tsis tau zoo. Peb tau pib ua khub tshiab nrog cov qub tub rog no tshwj xeeb rau cov haujlwm tseem ceeb ntawm kev ua haujlwm, khaws cov kev paub tsis meej.

Saib tom ntej: Lub Ntse Sib Koom?

Muaj kev sib tham txog ntse fasteners nrog embedded sensors los saib xyuas preload. Kuv tsis ntseeg txog kev siv dav. Tus nqi, complexity, thiab durability nyob rau hauv hnyav industrial ib puag ncig yog loj hurdles. Txog tam sim no, kev siv tswv yim ntau dua yog siv ultrasonic bolt elongation ntsuas rau qhov tseem ceeb, ib qho kev teeb tsa zoo li lub hauv paus loj turbine. Nws muab kev ntsuas ncaj qha rau koj, bypassing tag nrho cov kev sib txhuam sib txawv. Nws kim thiab qeeb, tab sis rau kev sib koom ua ke koj yeej tsis xav ua tsis tiav, nws yog qhov kawg kuaj xyuas.

Qhov tiag frontier, nyob rau hauv kuv saib, yog nyob rau hauv tsim rau disassembly thiab txij nkawm. Sustainable machinery yuav tsum tau muab kev pab. Anti-loosing tech uas seizes khoom tom qab tsib xyoos (Kuv tab tom saib koj, qee cov tshuaj threadlockers) yog qhov ntxeev ntawm kev ruaj ntseg. Qhov zoo tshaj plaws yog ib qho kev sib koom ua ke uas nyob twj ywm thaum ua haujlwm tab sis tuaj yeem disassembled nrog cov cuab yeej txheem thaum kho dua tshiab. Tias yog vim li cas kuv lean rau txhua yam, reusable locking ntsiab. Tej zaum lawv yuav xav tau kev hloov pauv tom qab ob peb lub voj voog, tab sis qhov ntawd zoo dua li txiav los yog khawb tawm lub bolt thiab ua rau cov khoom siv niam txiv puas tsuaj.

Thaum kawg, nws yog qhov kev ua si systems. Koj tsis tuaj yeem tsuas yog bolt ntawm sustainability. Nws pib nrog kev sib koom ua ke zoo, xaiv qhov tsim nyog, ruaj khov kho tshuab rau ib puag ncig, ua tiav nrog qhov tseeb, thiab kev npaj rau tag nrho lub neej. Cov tuam txhab uas muab cov khoom siv lub cev thiab daim ntawv thov kev txawj ntse, zoo li pab neeg ntawm Zitai Fasteners tawm ntawm qhov loj Handan ntau lawm puag, ua cov koom tes, tsis yog cov neeg muag khoom xwb. Vim tias qhov ruaj khov ruaj khov tshaj plaws yog qhov koj nruab kom raug, ib zaug, thiab tom qab ntawd tsis nco qab txog lub neej ntawm lub tshuab.
