I. Kev Npaj Ua Ntej Kev Kho
1. Ua ntej, daws cov teeb meem tseem ceeb: xyuas kom meej tias txoj siv conveyor tsis muaj qhov sib tsoo, hnav cov chais, lossis cov roj / roj tsim rau ntawm nws qhov chaw, txhawm rau tiv thaiv slippage lossis siv misalignment tsis tshwm sim txawm tias tom qab hloov kho.
2. Tsim kom muaj cov qauv kev nruj nruj: Rau cov qauv siv lub teeb yuag PVC conveyor siv, kev pom zoo pib nruj ntawm 5-10 N / mm (xws li siv dav) yog qhia. Rau hnyav-lub luag haujlwm lossis ntev- kev sib kis, siv qhov kawg ntawm qhov no. Thaum lub sij hawm hloov kho, tsis txhob tshaj qhov pom zoo siab tshaj plaws tus nqi kom tsis txhob ceev txoj siv tawv.
II. Kev kho cov txheej txheem rau cov khoom sib txawv Tensioning
1. Ntsia hlau- hom Tensioning Devices (Feem ntau ntawm cov khoom me me, luv luv -nyob deb conveyors)
Ua ntej, loosen lub fixing ceev nyob rau ntawm ob sab ntawm lub tensioning ntaus ntawv.
Tig lub tensioning bolts ntawm ob sab * ib yam thiab ib txhij *: Yog hais tias yuav tsum tau muaj zog nro, tig lub bolts sab hauv nyob rau hauv unison rub tus menyuam rov qab, yog li ceev txoj siv. Yog tias qhov nro ntau dhau, tig lub bolts nyob rau hauv qhov kev taw qhia kom cov menyuam txav mus rau pem hauv ntej, yog li loosening txoj siv.
Thoob plaws hauv txoj kev hloov kho, xyuas kom meej tias sab hauv / sab nraud mus ncig ntawm lub bolts ntawm ob sab tseem zoo ib yam. Qhov no tau lees tias cov menyuam tseem nyob rau tib lub sijhawm thiab qhov nro yog sib npaug ntawm txoj siv dav dav, tiv thaiv kev sib raug zoo los ntawm qhov tsis sib xws.
2. Lub ntiajteb txawj nqus (Counterweight) Tensioning Devices (Rau ntev-nruab deb/hnyav- lub luag haujlwm conveyors)
Txheeb xyuas txoj haujlwm ntawm qhov ntsuas qhov hnyav: Yog tias qhov ntsuas qhov ntsuas tau mus txog nws qhov qis tshaj qhov txwv tsis tau qhov nro tseem tsis txaus, yuav tsum tau ntxiv qhov hnyav ntxiv.
Yog hais tias qhov counterweight txoj hauj lwm siab dhau lawm - qhia txog kev nro ntau dhau - tsuas yog tshem tawm qhov hnyav blocks maj mam kom txog thaum qhov kev xav tau nruj.
Tom qab kev hloov kho, muab qhov ntsuas qhov ntsuas ze rau nruab nrab ntawm nws txoj kev mus ncig kom tau qhov chaw txaus them nyiaj rau yav tom ntej siv elongation.
3. Carriage-type / Hydraulic Tensioning Devices
Carriage-type Tensioning: Kho txoj hauj lwm ntawm lub tensioning carriage; kev nro yog tswj los ntawm kev hloov lub tsheb thauj mus los ntawm kev mus los. Thaum qhov xav tau txoj hauj lwm mus txog, tsuas yog koom nrog thiab kaw cov pins qhov chaw kom ruaj lub tsheb thauj mus los.
Hydraulic Tensioning: Ncaj qha kho tus nqi siab nyob rau hauv hydraulic system. Teem lub siab rau qhov tshwj xeeb parameter sib haum rau txoj siv tawv nruj, tom qab ntawd koom nrog lub siab - tuav mechanism los xauv qhov chaw. III. Tshaj tawm -Txoj Cai Tswj Xyuas Kev Kho Kom Zoo
Thaum qhov kev hloov kho ntawm cov khoom siv ua tiav, pib cov cuab yeej thiab ua haujlwm hauv qhov tsis muaj - thauj khoom rau 30 feeb.
Qhov kev hloov kho tau pom tias ua tiav yog tias muaj raws li hauv qab no:
1. Thaum lub sijhawm ua haujlwm, tsis muaj kev swb lossis kev siv tsis tu ncua;
2. Nyob rau hauv seem rov qab, lub sag ntawm txoj siv conveyor tsis pub tshaj 2% ntawm idler spacing;
3. Thaum manually nias rau ntawm qhov chaw ntawm txoj siv conveyor, lub deflection yog nyob nruab nrab ntawm 3-5 mm, thiab txoj siv tawv rebounds sai sai thaum tso tawm.
Cov ntsiab lus tseem ceeb
1. PVC conveyor siv tau ib txwm muaj kev ncab thiab slackening tom qab kev teeb tsa. Nws raug nquahu kom rov- tshuaj xyuas thiab ua kom zoo- kho txoj siv tawv nruj 1-2 lub lis piam tom qab qhov kev hloov pauv thawj zaug kom tsis txhob muaj kev poob qis los ntawm qhov ua rau slippage.
2. Yog tias slippage txuas ntxiv txawm tias tom qab kho txoj siv sia mus rau nws qhov siab tshaj plaws, qhov teeb meem tsis cuam tshuam nrog kev nro. Nyob rau hauv cov ntaub ntawv no, xyuas seb qhov teeb meem yog tshwm sim los ntawm hnav chais los yog roj / roj buildup ntawm cov menyuam nto; ntxuav los yog hloov cov yob raws li qhov tsim nyog.
