Hauv kev ua steel, chaw thau khoom thiab tshem tawm, thiab kev tsim khoom siv, steel phaj nqa electromagnets yog qhov tseem ceeb hoisting khoom. Lawv qhov kev nqa nqa ncaj qha txiav txim siab ua haujlwm ua haujlwm, kev nyab xeeb, thiab cov nqi khiav haujlwm. Tau ua haujlwm hauv kev lag luam hoisting tau ntau xyoo, kuv feem ntau ntsib cov lus tawm tswv yim los ntawm cov npoj yaig: "Vim li cas tib lub steel phaj nqa electromagnet qee zaum yooj yim nqa cov hlau phaj hnyav, thaum lwm lub sijhawm nws tsis tuav ruaj khov thiab txawm tias muaj kev pheej hmoo slipping?" Qhov no tsis yog qhov teeb meem zoo, tab sis yog qhov tshwm sim ntawm ntau yam cuam tshuam rau electromagnet qhov kev nqa khoom. Niaj hnub no, raws li kev ua haujlwm hauv pem hauv ntej, kuv yuav rhuav tshem rau qhov tseem ceeb uas cuam tshuam rau kev nqa ntawm steel phaj lifting electromagnets thiab qhia cov tswv yim optimization tswv yim los pab koj kom tsis txhob muaj kev ua haujlwm pitfalls thiab txhim kho lifting efficiency thiab kev nyab xeeb.
Ua ntej, nws yog ib qho tseem ceeb kom nkag siab tias qhov tseem ceeb ntawm asteel phaj lifting electromagnet's lifting kev ua tau zoo nyob rau hauv "adhesion ntawm lub electromagnetic quab yuam thiab steel phaj, thiab stability ntawm lub zog thov." Ib qho tseem ceeb cuam tshuam rau ob qhov tseem ceeb no yuav ncaj qha ua rau txo qis kev ua haujlwm ntawm kev nqa. Ntawm cov no, cov tuab thiab cov khoom qib ntawm cov hlau phaj nws tus kheej yog qhov tseem ceeb hauv kev txiav txim siab nqa kev ua tau zoo thiab tseem yog qhov yooj yim tshaj plaws. Cov thicknesses sib txawv ntawm cov hlau phaj xav tau ntau theem ntawm electromagnetic quab yuam. Cov hlau nyias nyias (tsawg dua lossis sib npaug li 10 hli tuab) tsis tas yuav muaj zog ntau dhau, tab sis muaj zog dhau heev tuaj yeem ua rau lub phaj deform. Cov phaj tuab tuab (Ntau dua lossis sib npaug ntawm 20mm tuab) yuav tsum muaj lub zog hluav taws xob txaus kom kov yeej lawv tus kheej qhov hnyav thiab ua kom ruaj khov. Cov khoom qib ntawm steel phaj kuj tseem ceeb heev. Ordinary carbon steel daim hlau muaj qhov sib nqus zoo permeability, uas ua rau pom kev ua haujlwm zoo. Cov ntaub ntawv uas tsis zoo sib nqus permeability, xws li stainless hlau thiab alloy steel daim hlau, tsis muaj zog electromagnetic quab yuam, ua rau lifting nyuaj. Qhov no yog qhov laj thawj tseem ceeb vim li cas ntau tus neeg nqa khoom feem ntau ntsib kev tsis zoo thaum nqa cov khoom tshwj xeeb xws li cov phaj hlau.
Qhov thib ob, kev huv huv ntawm cov phaj hlau yog qhov tseem ceeb rau kev sib txuas ntawm electromagnet thiab phaj, ncaj qha txiav txim siab nqa kev nyab xeeb. Hauv kev ua haujlwm tiag tiag, steel phaj nto inevitably sau impurities xws li xeb, roj, thiab nplai. Cov impurities zoo li tsis tseem ceeb no tuaj yeem cuam tshuam kev sib cuag ntawm electromagnet thiab steel phaj. Xeb thiab nplai tsim ib txheej insulating, thaum roj txo kev sib txhuam ntawm qhov chaw sib cuag. Ob qho tib si ua rau txo qis hauv electromagnetic attraction, thiab txawm tias "dag attraction," ua rau cov hlau phaj nws yuav plam thaum hoisting. Raws li kev paub dhau los, peb muab cov neeg ua haujlwm siab tawv los ntxuav cov phaj hlau ua ntej txhua qhov haujlwm hoisting, tshwj xeeb tshaj yog tshem cov xeb thiab roj. Ib qho yooj yim so ho txhim kho cov adsorption stability ntawm lubHlau Phaj Lifting Electromagnet, ua nws txoj kev lag luam zoo tshaj plaws los txhim kho hoisting efficiency.
Cov huab cua sib txawv ntawm cov electromagnet thiab steel phaj yog ib qho yooj yim overlooked tab sis muaj kev cuam tshuam loj heev. Qhov sib txawv ntawm huab cua yog qhov kev ncua deb ntawm electromagnet's adsorption phaj thiab steel phaj nto. Txawm tias qhov sib txawv me me ntawm 0.5 hli tuaj yeem ua rau muaj qhov cuam tshuam loj ntawm electromagnetic cuam tshuam -vim qhov sib nqus ntawm qhov sib txawv ntawm huab cua. Qhov loj dua qhov sib txawv ntawm huab cua, qhov ntau dua qhov sib nqus teb, thiab lub zog adsorption tsis muaj zog. Hauv kev ua haujlwm tiag tiag, qhov sib txawv ntawm huab cua feem ntau tshwm sim rau ob qho laj thawj: ua ntej, cov hlau phaj nto tsis sib xws los yog muaj qhov sib txawv, ua rau nws tsis tuaj yeem ua tiav tag nrho; thib ob, electromagnet disc nto yog hnav, deformed, los yog muaj impurities txuas, cuam tshuam cov nyhuv adhesion. Yuav kom daws tau qhov teeb meem no, peb cov tswv yim tswv yim yog: tsis tu ncua xyuas cov electromagnet disc nto, zom thiab kho qhov chaw hnav, thiab ntxuav cov impurities; rau cov hlau tsis sib xws, ib daim ntawv nyias ntawm cov hlau tuaj yeem muab tso rau ntawm qhov chaw sib cuag kom txo tau cov pa tawm thiab xyuas kom nruj adhesion.
Qhov kub ntawm qhov chaw ua haujlwm tsis ncaj qha cuam tshuam rau kev nqa ntawm steel phaj lifting electromagnets. Cov ntsiab lus tseem ceeb ntawm steel phaj lifting electromagnet yog lub kauj, thiab nws cov efficiency yog ho cuam tshuam los ntawm kub. Ntawm qhov kub thiab txias (-20℃txog 60 degree), lub coil ua haujlwm ib txwm muaj kev ruaj khov electromagnetic attraction; Txawm li cas los xij, nyob rau hauv qhov kub ntawm - ib puag ncig kub (xws li steel smelting rhiav, qhov kub siab tshaj los yog sib npaug li 80 degree), lub kauj heats li, ua rau muaj zog tiv thaiv thiab tsis muaj zog electromagnetic attraction. Piv txwv li, nyob rau hauv ib puag ncig uas tsis muaj kub (tsawg dua los yog sib npaug rau -20 degree), lub coil lub conductivity txo, zoo li cuam tshuam rau attraction thiab tej zaum yuav ua rau cov khoom malfunction. Yog li ntawd, thaum ua hauj lwm nyob rau hauv huab cua kub ib puag ncig, nws yog pom zoo kom xaiv tshwj xeeb steel phaj lifting electromagnets uas yog resistant rau ob qho tib si kub thiab tsis kub, thiab siv kom zoo cua sov dissipation los yog rwb thaiv tsev ntsuas los tiv thaiv kub los ntawm kev cuam tshuam lifting kev ua tau zoo.
Kev tswj ruaj khov ntawm qhov hluav taws xob thiab qhov tam sim no yog ib qho tseem ceeb rau kev ua kom ruaj khov kev ua haujlwm ntawm lub tshuab electromagnet. Electromagnetic attraction ntawm asteel phaj lifting electromagnet yog ncaj qha ntsig txog qhov voltage thiab tam sim no. Yog hais tias qhov voltage thiab tam sim no tsawg dhau lawm, lub zog magnetic teb generated los ntawm lub kauj yog tsis txaus, ua rau tsis muaj zog attraction. Yog tias qhov hluav taws xob thiab tam sim no siab dhau lawm, nws tsis yog tsuas yog ua rau lub zog siv hluav taws xob xwb tab sis kuj ua rau lub coil overheat, ua rau kev laus, thiab tseem hlawv cov khoom siv, ua rau nws lub neej luv. Hauv kev xyaum, peb muab cov khoom siv nrog rau siab voltage thiab tam sim no regulators los saib xyuas qhov voltage thiab tam sim no hloov nyob rau hauv lub sij hawm ntawm lub sij hawm, kom ntseeg tau tias lawv nyob ruaj khov nyob rau hauv cov khoom ntsuas ntau yam. Qhov no tiv thaiv kev ua haujlwm tsis zoo vim qhov hloov pauv ntawm qhov hluav taws xob thiab ua rau cov khoom siv lub neej ntev.
Dhau li ntawm tsib yam tseem ceeb uas tau hais los saum no, kev saib xyuas niaj hnub thiab calibration kuj tseem ceeb heev rau kev txhim kho kev nqa khoom. Ntau tus kws tshaj lij hauv kev lag luam tsom tsuas yog siv cov cuab yeej siv tab sis tsis saib xyuas kev ua haujlwm niaj hnub ua, ua rau muaj kev poob qis hauv cov khoom siv hluav taws xob lifting. Raws li kev saib xyuas ntau xyoo, peb tau sau tseg ob lub ntsiab lus tseem ceeb: ua ntej, tsis tu ncua ntxuav lub electromagnet lub phaj adsorption kom huv si thiab tiv thaiv impurities los ntawm kev cuam tshuam adhesion; thib ob, tsis tu ncua calibrate cov cuab yeej, xyuas cov kev ua tau zoo ntawm cov tub ntxhais Cheebtsam xws li cov kauj thiab sib nqus core, thiab tam sim ntawd hloov cov laus qhov chaw kom paub tseeb tias cov khoom nyob rau hauv kev pom kev ua hauj lwm. Ua ob yam no zoo tsis tsuas yog txhim kho lifting efficiency tab sis kuj txo cov cuab yeej tsis ua hauj lwm thiab txo nqi txij nkawm.
Hauv cov ntsiab lus, cov yam ntxwv cuam tshuam rau kev nqa nqa ntawm steel phaj lifting electromagnets koom nrog ntau yam, suav nrog steel phaj nws tus kheej, qhov chaw ua haujlwm, khoom siv, thiab kev saib xyuas. Teeb meem nyob rau hauv ib qho ntawm cov cheeb tsam no yuav cuam tshuam cov txiaj ntsig nqa. Rau cov tuam txhab lag luam koom nrog kev nqa nqa, nkag siab txog cov kev cuam tshuam no thiab ua kom muaj kev ua haujlwm zoo txhua hnub thiab kev saib xyuas tuaj yeem txhim kho kev nqa nqa, ua kom muaj kev nyab xeeb ntawm kev ua haujlwm, txuas ntxiv cov cuab yeej siv, thiab txo cov nqi khiav lag luam. Peb cia siab tias cov kev paub dhau los niaj hnub no tuaj yeem pab koj kom tsis txhob muaj kev ua haujlwm tsis zoo thiab tso cai rau steel phaj lifting electromagnets ua tiav lawv lub peev xwm. Yog tias koj ntsib cov lus nug thaum siv cov cuab yeej siv lossis kev saib xyuas, thov sau cov lus los sib tham thiab qhia txog cov tswv yim ua ntej.
