Cov yam ntxwv & kev ua tau zoo

Fail - nyab xeeb ib txwm - kaw tsim: Caij nplooj ntoos hlav - siv braking thaum lub hwj chim - tawm, hluav taws xob tso tawm thaum fais fab tuag, ua kom muaj kev nyab xeeb thaum muaj hluav taws xob.

DC - tsav efficiency: Dedicated rau DC - cov khoom siv fais fab; Kev tso tawm ruaj khov, tsis tshua muaj cua sov, thiab kev sib kis tau zoo ntawm cov ntsiab lus pob khawm nrog tus kheej - lubricating bearings.

Eco - tus phooj ywg & ruaj khov: Tsis yog - asbestos nres hauv ob sab phlu; txhim khu kev qha kev ua tau zoo, tsis tshua muaj suab nrov, thiab kho qhov sib txawv kom yooj yim txij nkawm.

Hloov compatibility: Raws li ZWZ3 series installation qhov ntev rau seamless hloov khoom dua tshiab.

Tej kev siv

Haum rau deceleration thiab nres nres ntawm DC - tsav cranes, winches, metallurgical machinery, thiab chaw nres nkoj thauj khoom / unloading khoom, ntsib nruab nrab - load, nruab nrab - zaus braking xav tau.

Txhim kho ZWZB - 500/400 ib txwm - kaw electromagnetic nruas nres yuav tsum tau ua raws li cov txheej txheem kev nyab xeeb, cov cuab yeej siv tau zoo, kev sib txuas hluav taws xob, thiab kev hloov pauv kom ntseeg tau tias kev ua haujlwm ruaj khov. Hauv qab no yog ib kauj ruam - los ntawm - kauj ruam qhia installation:

Ua ntej - Kev Npaj Txhim Kho

Kev Nyab Xeeb & Kev Tshuaj Xyuas

Txiav tawm lub hwj chim ntawm cov khoom siv thiab dai daim ntawv ceeb toom. Hnav cov iav tiv thaiv xws li hnab looj tes thiab tsom iav.

Xyuas seb cov khoom siv nres (brake spring, electromagnet, brake shoe, non - asbestos lining, self -} lubricating bearing) puas zoo, tsis muaj kab nrib pleb, deformation, los yog hnav ntau dhau. Xyuas kom tseeb tias qhov sib txuam 500mm nres nruas tsis muaj khawb, tawm - ntawm - roundness, lossis roj stains.

Paub meej tias lub hauv paus mounting thiab ntsia liaj qhov rooj qhov ua tau raws li qhov yuav tsum tau muaj ntawm ZWZB - 500/400 installation qhov ntev (qhov nruab nrab ntawm qhov nruab nrab yog li 450mm), thiab ntxuav lub mounting nto kom tshem tawm cov roj stains, xeb, thiab burrs.

Tool & Accessory Npaj

Npaj torque ciaj ntswj, ntsuas qhov ntsuas (0.6-}0.8mm), theem, shim, qhib - kawg ciaj ntswj, thiab cov cuab yeej hluav taws xob rwb thaiv tsev.

Xyuas kom paub tias cov khoom siv xws li kho cov ntsia hlau, cotter pins, sib npaug - retraction springs, thiab phau ntawv tso tawm levers tiav lawm.

Mechanical Installation Cov kauj ruam

Mounting Base Kho

Muab lub hauv paus nres rau ntawm qhov ua ntej - ntsia hlau bracket, dlhos lub mounting qhov, thiab siv sib txuam siab - lub zog bolts los kho nws thaum xub thawj (tsis txhob nruj nreem). Siv ib theem los xyuas kom meej lub hauv paus yog kab rov tav, thiab ntxiv shims nyob rau hauv lub hauv paus yog tias tsim nyog rau kev kho.

Tighten lub mounting bolts diagonally thiab nyob rau hauv cov theem mus rau lub torque teev (feem ntau yog 8.8 - qib bolts nrog ib tug torque ntawm 80-100 N·m, raws li cov chaw tsim tshuaj paus phau ntawv).

Nres lub cev sib dhos

Rau sab - mounted installation, tshem tawm tus pin txuas lub hauv paus thiab tus nres caj npab, viav vias caj npab nce, thawb tus nres mus rau txoj hauj lwm uas tus brake khau yog ua raws li 500mm nruas, thiab rov pib dua lub nres nres.

Reinstall qhov sib npaug - retraction caij nplooj ntoos hlav, tus pin txuas, thiab ruaj ntseg nws nrog ib tug cotter tus pin. Xyuas kom lub pob khawm cov ntsiab lus ntawm tus nres caj npab yog hloov tau yam tsis muaj jamming.

Txhim kho phau ntawv tso tawm mechanism, thiab sim tias qhov kev tso tawm yog du thiab tuaj yeem kaw qhov chaw.

Txoj hauj lwm Calibration

Kho txoj hauj lwm ntawm tus nres kom lub cylindrical nto ntawm tus brake khau yog nyob rau tib lub sij hawm mus rau lub axis ntawm lub nruas nres, thiab qhov sib txawv ntawm ob sab ntawm lub nruas yog uniform. Lub coaxiality sib txawv yuav tsum tsis txhob ntau tshaj 0.2 hli.

Kev sib txuas hluav taws xob

Txuas lub DC electromagnet kauj rau DC 110V / 220V fais fab mov (cov tswj Circuit Court siv AC 380V, 50Hz). Ua raws li cov kab kos duab, paub qhov txawv ntawm qhov zoo thiab qhov tsis zoo, thiab txuas cov xov hlau ruaj khov.

Siv cov cua sov - shrinkable tubes los yog rwb thaiv tsev daim kab xev los thaiv cov pob qij txha los tiv thaiv luv luv Circuit Court los ntawm ya raws thiab roj paug. Nruab ib lub surge protector thiab thermal relay nyob rau hauv Circuit Court los tiv thaiv electromagnet.

Tshawb xyuas cov rwb thaiv tsev tiv thaiv ntawm lub kauj nrog megger; nws yuav tsum muaj ntau dua lossis sib npaug li 1MΩ ntawm chav tsev kub kom ntseeg tau tias muaj kev nyab xeeb hluav taws xob.

Gap Adjustment & Commissioning

Gap Chaw

Thaum lub hwj chim tawm, tus nres yog nyob rau hauv lub braking lub xeev. Loosen cov txiv ntseej kho ntawm lub caj npab nres, thiab thaum lub hwj chim yog nyob rau (lub electromagnet yog energized thiab tso tawm), siv ib tug 0.6-0.8mm feeler gauge los kho qhov sib txawv retraction ntawm lub brake khau. Xyuas kom qhov khoob ntawm ob sab ntawm lub nruas nres yog sib npaug thiab nyob rau hauv qhov ntau ntawm 0.6-0.8mm.

Tighten lub ntsuas phoo tom qab hloov kho kom tsis txhob xoob thaum lub sijhawm ua haujlwm.

Kev Xeem Ua Haujlwm

Fais fab rau thiab sim qhov kev tso tawm. Lub tshuab hluav taws xob yuav tsum rub kom zoo, thiab cov khau nres yuav tsum thim rov qab kom tsis txhob rub lub nruas. Lub sijhawm teb yuav tsum tsawg dua lossis sib npaug li 0.5s.

Fais fab tuag los ntsuam xyuas cov nyhuv braking. Lub nres yuav tsum ceev ceev tuav lub nruas nyob rau hauv qhov kev txiav txim ntawm lub caij nplooj ntoos hlav quab yuam, nrog ib tug ntaus nqi braking torque ntawm 400N·m, tsis muaj suab nrov txawv txav, thiab ruaj khov braking.

Ntsuam xyuas phau ntawv tso tawm ua haujlwm dua kom ntseeg tau tias nws tuaj yeem tso tus nres nres kom ntseeg tau thaum lub hwj chim tawm.

Kev Xeem Ua Haujlwm Nruam

Khiav ntawm qhov ntsuas zaus (tsawg dua lossis sib npaug li 720 cycles / h), xyuas kom muaj cua sov ntawm lub tshuab hluav taws xob (qhov kub ntawm qhov chaw yuav tsum tsis pub tshaj 80 degree), thiab paub meej tias lub braking torque thiab kev ua haujlwm zoo sib xws raws li qhov yuav tsum tau ua.

Tshaj tawm - Kev Tshawb Fawb & Kev Txhim Kho Cov Lus Qhia

Tom qab kev teeb tsa, rov kuaj xyuas lub bolt nruj, qhov sib txawv me me, thiab hluav taws xob rwb thaiv tsev.

Tsis tu ncua xyuas qhov hnav ntawm lub brake hauv ob sab phlu (hloov thaum lub thickness tsawg dua 5 hli), elasticity ntawm lub caij nplooj ntoos hlav, thiab lub lubrication ntawm lub pob khawm.

Rau sab nraum zoov lossis corrosive ib puag ncig, siv los tiv thaiv - corrosion hloov qhov chaw thiab tsis tu ncua ntxuav qhov chaw nres tsheb.
