Lub overload txwv hloov ntawm lub tshuab hluav taws xob hoist yog ib qho tseem ceeb ntawm kev ruaj ntseg cuab yeej los xyuas kom meej qhov kev vam meej ntawm kev ruaj ntseg lifting ua hauj lwm. Nws yog dav siv rau CD MD hom hlau hlua hoists ntawm choj cranes thiab gantry cranes.
Daim duab tiag tiag ntawm hluav taws xob hoist overload txwv hloov
Txoj cai ua haujlwm
Lub overload txwv hloov ua haujlwm raws li cov neeg kho tshuab lossis hluav taws xob tshawb pom ntawm lub zog ntau dhau los yog qhov hnyav ntawm lub hoist. Thaum lub hoisting load tshaj lub peev xwm ntawm lub hoist, lub overload txwv hloov yog triggered.Thaum lub load mus txog qhov siab tshaj plaws qhov ceeb thawj (uas yuav tsum tau pre-set thaum lub sij hawm installation), lub hloov ua hauj lwm, xws li mechanically los yog electronically. lub caij nplooj ntoos hlav-loaded lever los yog lwm yam mechanical Cheebtsam kom nkag siab thaum lub load exerts ntau tshaj li lub zog teev. Thaum lub sijhawm no hla dhau, lub zog txav thiab qhib qhov hloov, uas tom qab ntawd cuam tshuam rau lub zog hluav taws xob.Cov qauv no siv cov khoom siv hluav taws xob, cov ntsuas ntsuas, lossis cov hlwb los ntsuas cov load kom raug. Thaum lub tshuab hluav taws xob pom tias muaj kev thauj khoom ntau dhau, nws xa cov teeb liab mus rau lub kaw lus tswj kom nres lub hoist lossis ua qee yam kev kho (xws li txo qis lub load).Thaum tshwm sim, lub overload txwv hloov yuav txiav tawm lub hwj chim rau lub hoist motor, tiv thaiv kev nqa lossis kev ua haujlwm qis dua ntxiv. Qhov no feature pab tiv thaiv kev raug mob, kev puas tsuaj rau lub hoist, thiab tej zaum yuav muaj kev ruaj ntseg txaus ntshai vim overloading.Tom qab ib tug overloading mob yog cleared (lub load ntau dhau raug tshem tawm), qhov txwv mus rau reset manually los yog cia li raws li cov kev tswj system tsim. Qhov kev txiav txim rov pib dua no rov ua haujlwm li qub ntawm lub hoist, cia nws ua haujlwm nyob rau hauv qhov tsis muaj kev nyab xeeb.
Txoj Kev Txhim Kho
1. Muab qhov hnyav ntawm qhov hloov mus rau hauv txoj hlua hlau thiab txuas nws ruaj khov nrog U-bolts.
2. Kho lub cev hloov mus rau lub bracket ntawm lub hoist vaj tse nrog bolts.
3. Txuas cov neeg sib cuag ntawm qhov hnyav thiab lub cev hloov nrog cov hlua, thiab xyuas seb cov kev sib tiv tauj puas hloov tau.
4. Fais fab ntawm qhov kev xeem khiav, xyuas thiab debug qhov hloov mus kom ntseeg tau tias nws ua tau raws li qhov yuav tsum tau ua ntawm kev siv ntawm qhov chaw.
Nco tseg: Cov cuab yeej hloov pauv no muaj qhov txwv tsis pub ua haujlwm tsuas yog thaum lub hoist nuv nyob rau hauv txoj haujlwm txwv. Thaum tus nuv nyob rau hauv txoj hauj lwm qis qis, tsis muaj qhov txwv tsis pub ua.
Lub overload txwv hloov yog feem ntau ntsia ze ntawm tus nuv los yog lub lifting mechanism ntawm hluav taws xob hoist. Nws yuav tsum tau positioned nyob rau hauv ib txoj kev uas nws saib xyuas lub lifting los yog rub quab yuam thov mus rau lub hoist.Lub overload txwv hloov yog wired mus rau hauv lub tswj system ntawm hluav taws xob hoist. Nws txuas rau lub cev muaj zog thiab lwm yam khoom siv hluav taws xob los saib xyuas lub nra. Qhov hloov pauv feem ntau yog ntsia rau hauv series nrog lub cev muaj zog lub zog hluav taws xob. Qhov no txhais tau hais tias thaum lub load ntau tshaj li qhov pre-set tus nqi, qhov hloov pauv cuam tshuam lub hwj huam mov rau lub cev muaj zog, yog li nres lub hoist.
Nyob rau hauv cov ntsiab lus lub overload txwv hloov mus rau mounted ncaj qha mus rau lub hoist nuv los yog los ntawm ib tug txhawb nqa bracket. Kev sib raug zoo thiab kev hloov kho yog tsim nyog los xyuas kom meej qhov kev saib xyuas ntawm cov load. Qhov no suav nrog calibrating tus hloov mus rau qhov tshwm sim ntawm qhov xav tau tshaj tus nqi.Los ntawm kev ua raws li cov lus qhia no, hluav taws xob hoists nruab nrog cov kev txwv hla dhau tuaj yeem ua haujlwm nyab xeeb thiab ua tau zoo thaum muab kev tiv thaiv cov xwm txheej dhau.
