Aluminium txiv neej nqa tau dav siv hauv kev ua haujlwm hauv huab cua vim lawv cov yam ntxwv sib sib zog nqus thiab ruaj khov.

Txawm li cas los xij, cov saw hlau, raws li nws cov tub ntxhais kis tau tus mob thiab cov khoom siv thauj khoom, thaum nws ntog, nws yuav tsis tsuas yog ua rau cov cuab yeej ua rau tuag tes tuag taw, tab sis kuj ua rau muaj kev nyab xeeb loj heev.Hnub no peb yuav txheeb xyuas qhov ua rau cov saw hlau poob rau hauv qhov tob, thiab muab cov kev daws teeb meem thiab kev saib xyuas kom meej.

Plaub qhov laj thawj tseem ceeb rau cov saw hlau poob

1. Txhua hnub hnav thiab qaug zog

Hauv kev siv cov saw ntev ntev, yuav muaj kev sib txhuam tsis tu ncua ntawm tus pin ncej thiab lub tes tsho, uas ua rau qhov ntev ntawm qhov txuas (elongation).

Thaum qhov ntev ntawm cov saw hlau ntev tshaj qhov kev tso cai, nws txoj kev koom tes nrog lub sprocket yuav ua tsis sib haum, thiab nws yuav ua rau cov hniav hla thiab tawm. Qhov no yog qhov laj thawj tshaj plaws.

2. Kev teeb tsa tsis raug thiab commissioning

* Tsis xis nyob tensioning:cov saw yog xoob dhau kom haum nruj nrog lub sprocket, thiab nws yooj yim rau co thiab poob; Yog tias cov saw hlau nruj dhau lawm, nws yuav ua rau hnyav hnyav thiab ua suab nrov txawv txav.

* Lub sprocket tsis sib haum:Lub active sprocket thiab lub sprocket uas tau tsav tsis nyob rau tib lub dav hlau, uas yuav ua rau cov saw hlau tiv thaiv lateral zog thaum lub sij hawm ua hauj lwm thiab yuav "sib cais" los ntawm txoj kev.

3. Kev ua haujlwm thiab ib puag ncig

* Kev ua haujlwm overload:Qhov nro loj heev uas tshaj qhov ntsuas load yuav ncaj qha rau cov saw lossis deform nws.

* Sab nraud cuam tshuam:Thaum lub sij hawm txav los yog ua haujlwm ntawm cov khoom siv, cov saw hlau yog sib tsoo, uas yuav ua rau qhov txuas mus rau deform los yog tus pin ncej kom loosen.

* Tsis muaj lubrication:Hauv cov huab cua ntub, yog tias cov saw hlau tsis tu ncua, corrosion thiab hnav yuav nrawm dua, tawv yuav txo qis, thiab brittleness yuav nce.

4. Deformation lossis puas rau qhov chaw

Kev hnav thiab tsim kua muag ntawm cov hniav sprocket, deformation los yog poob ntawm cov saw hlau tiv thaiv (cov ntaub thaiv npog), thiab cov kab nrib pleb los yog deformation ntawm cov kev sib txuas lossis cov phaj sib koom ua ke ntawm cov saw hlau nws tus kheej yuav rhuav tshem cov kev sib raug zoo ntawm kev sib kis.

Thaum ntsib kev poob, yuav ua li cas nrog nws kom raug thiab ceev?

Kev nyab xeeb ua ntej! Thov ua cov kauj ruam hauv qab no tam sim:

1. Nres tam sim ntawd: Nias lub khawm nres thaum muaj xwm ceev, txiav tawm tag nrho cov khoom siv hluav taws xob, thiab dai daim ntawv ceeb toom "Tsis muaj haujlwm".

2. Unloading siab: xyuas kom meej tias lub lifting platform tau txo qis mus rau qhov qis tshaj plaws los yog muaj kev nyab xeeb thiab ruaj khov los ntawm kev txhawb nqa nruj (xws li kev txhawb nqa ntoo) kom tso tawm tag nrho cov kev nro ntawm cov saw hlau.

3. Kev tshuaj xyuas ua ntej: Nyob rau hauv qhov chaw ntawm kev ua kom muaj kev ruaj ntseg, saib xyuas qhov xwm txheej ntawm cov khoom tawg thiab xyuas kom pom tseeb qhov tawg, deformed lossis puas. Tsis txhob sim nruab nrog koj txhais tes liab qab lossis ua kev kho hauv lub xeev tsis zoo.

Peb, kev saib xyuas cov kauj ruam

Rau cov uas tsis yog cov kws tshaj lij, nws raug pom zoo kom hu rau lub chaw pabcuam kev saib xyuas hauv zos. Hauv qab no yog cov txheej txheem kho tus qauv rau cov kws tshaj lij:

1. Kev tshuaj ntsuam xyuas:

· Xyuas seb txhua qhov txuas puas hloov tau, ntsuas qhov elongation ntawm cov saw, thiab txiav txim siab seb nws puas yuav tsum tau hloov.

· Tshawb xyuas qhov hnav thiab kev sib tw ntawm ob lub sprockets.

· Xyuas seb cov saw hlau thiab cov ntaub thaiv npog puas puas lawm.

2. Hloov thiab hloov kho:

· Hloov cov saw: Yog hais tias cov saw hnav tshaj tus qauv, lub ntsiab thiab pab chains yuav tsum tau hloov nyob rau hauv ua khub kom zoo tib yam ntev thiab nro thiab tsis txhob unilateral quab yuam.

* Kho qhov tensioning degree: kho cov saw hlau kom tsim nyog nruj los ntawm cov tensioning bolts (feem ntau cov nyiaj sagging nyob rau hauv nruab nrab yog li ntawm 2% -4% ntawm qhov chaw nruab nrab ntawm ob sprockets).

* Kho qhov sprocket: Siv cov cuab yeej xws li laser centering instruments los xyuas kom meej tias lub ntsiab thiab qhev sprockets yog tag nrho ua ke.

3. Kev kuaj thiab txais:

· Tom qab kev teeb tsa tiav lawm, khiav thiab khiav yam tsis muaj kev thauj khoom los saib seb qhov kev sib koom ua ke ntawm cov saw hlau thiab cov sprocket puas du thiab seb puas muaj lub suab nrov txawv txav.

· Ua ib qho kev kuaj xyuas kom paub meej tias kev ua haujlwm ruaj khov thiab raug ua ntej nws tuaj yeem muab tso rau hauv ib txwm siv.

Kev tiv thaiv zoo dua li kev kho mob: tsim kom muaj kev saib xyuas tsis tu ncua, suav nrog kev tshuaj xyuas txhua hli ntawm cov saw saw thiab nro, lubrication peb lub hlis twg, thiab kev tshuaj xyuas txhua xyoo, uas tuaj yeem zam qhov tshwm sim ntawm qhov tsis ua haujlwm thiab ua kom muaj kev nyab xeeb ntawm kev ua haujlwm.
