Izizathu kunye nezisombululo zokungaphumeleli kwe-hoist yombane

Izizathu kunye nezisombululo zokungaphumeleli kwe-hoist yombane

1. Cinezela isitshixo sokuqala kwaye i-hoist yombane ayisebenzi

Ikakhulu kungenxa yokuba i-hoist ayiqhagamshelwanga kwi-voltage yokusebenza elinganisiweyo, kwaye ayikwazi ukusebenza.Ngokuqhelekileyo, kukho iimeko ezintathu:

(1) ingaba inkqubo yonikezelo lombane kukunika amandla unikezelo lwamandla ombane, ngokuqhelekileyo kusetyenziswa ipeni yokuvavanya, njengokungabikho kombane, ize ke isebenze emva konikezelo lombane; , Ukuqhawulwa kwesekethe okanye uqhagamshelwano olubi, kwakhona unokwenza i-hoist motor ayikwazi umbane, ibonakala ngolu hlobo lwemeko, idinga ukulungisa eyona nto iphambili, isekethe yokulawula, ukugcinwa kunye nokulungiswa, ukwenzela ukuba kuthintelwe iisekethe eziphambili kunye nokulawula izigaba ezintathu. Isigaba samandla emoto kwaye sitshiswe, okanye siphakamise ukusebenza kombane, ngequbuliso, kuya kufuneka siphakamise i-motor ukusuka kwintambo yamandla ukuqhawula endleleni, kuphela ukulawula kunye nokulawula isekethe yokuhambisa umbane, emva koko ucofe ukuqala kwaye umise ukutshintsha, jonga uhlalutyo kunye nolawulo. imeko yokusebenza yesekethe yombane, ukuba nengxaki yezixhobo zombane okanye iintambo zokulungiswa okanye ukutshintshwa, xa kuqinisekiswa inkosi kunye nolawulo lwesekethe ye-free-free, ukuseta kwakhona uvavanyo;Ngaphezu kwe-10%, i-torque yokuqalisa i-motor incinci kakhulu, yenza iimpahla zokuphakamisa i-hoist, kwaye ayikwazi ukusebenza, khangela igalelo lombane wemoto ilinganiswa nge-multimeter okanye i-voltmeter, njl, ngenxa yokuba i-voltage iphantsi kakhulu, ngokwenene. ukwenza i-motor ayikwazi ukuqala, i-voltage yenkqubo iya kubuyela kwesiqhelo phambi kokusetyenziswa kwe-hoist yombane.Ngamanye amaxesha, i-voltage ye-motor gourd iyinto eqhelekileyo, kwaye i-gourd ayisebenzi, ekufuneka ithathelwe ingqalelo ngenxa yezinye izizathu, ezifana: I-motor itshiswe phantsi, i-motor idinga ukutshintshwa xa ilungiswa; I-Calabash ayisetyenziswanga ixesha elide, ukugcinwa kakubi kunye nezinye izizathu ukwenzela ukuba ivili le-brake kunye ne-end cover cover ifile, ukuqala ivili lokuqhawula lingavuleki. I-motor ikhuphe kuphela isandi esithi "hum", ayinakunyuka, iselwa alinakusebenza.Ngeli xesha, kufuneka lisuse ivili lokuqhawuka, licoce indawo edlekileyo, liphinde livavanye; hayi ukujikeleza.Ukuba le meko ifunyenwe, kufuneka imiswe, kwaye i-motor kufuneka ihlaziywe okanye ithathelwe indawo ukuze kuqinisekiswe ukusebenza okuqhelekileyo kwe-hoist.Ukongezelela, ukusetyenziswa kwe-hoist overload yombane kunqatshelwe ngokungqongqo kwimveliso.Xa iimpahla zigqithisekile, i-hoist ayishukumisi iimpahla, i-motor yenza kuphela isandi esithi "hum", kwaye ayisebenzi.Xa inzulu, imoto iya kutshiswa, kwaye ibangele ingozi.

2. Isandi esingaqhelekanga senzeka xa i-hoist yombane isebenza

Electric hoist inkathazo eninzi, umzekelo, ulawulo lwezixhobo zombane, motor kunye reducer, etc wabonakala impazamo, isoloko sikhatshwa ingxolo engaqhelekanga, ingxolo yesikhundla kunye nobude kwaye abanayo umahluko, kunye nonobangela ingxaki kugcino olwahlukileyo, ufuna ukumamela ukubona ngakumbi, unokwenza ukusebenzisa, okanye ngokweempawu eziphosakeleyo zengxolo, ukumisela indawo yesandi, ukukhangela kunye nokulungiswa.

(1) Ingxolo engaqhelekanga iyenzeka kwisiphaluka solawulo kwaye yenza ingxolo “hum”.Ngokuqhelekileyo kubangelwa kukusilela koqhagamshelwano (njengoqhagamshelwano olubi lwe-AC contactor, ukungahambelani komgangatho wombane, undoqo wemagnethi ubambekile, njl. njl.).I-fault contactor kufuneka ijongwe kwaye ithathelwe indawo ukuba ayinakujongwa.

Ingxolo engaqhelekanga, (2) motor, kufuneka ime ngoko nangoko, khangela ukuba injini umsebenzi wesigaba esinye, okanye ukuthwala umonakalo, i-axis yokudibanisa ayithe tye, kwaye igumbi "litshayela", ezi ziya kwenza umatshini ube nomsindo ongaqhelekanga, ingxolo. yendawo yempazamo eyahlukileyo kunye nephezulu kwaye iphantsi kwaye ayivakali ngokwahlukileyo, ukusebenza kwesigaba esinye, i-motor evela kwisandi esinamandla kunye nesibuthathaka "esibhubhuzayo" isandi. ” isandi “sokungqusha – ginya”;Xa ishafti yesidibanisi ingachanekanga, okanye i-motor itshayelwe kancinane, yonke imotor ikhupha isandi “esibhubhuzayo” esiphezulu, esingasoloko sikhatshwa sisandi esibukhali nesirhabaxa. Ngamafutshane, ngokwengxolo eyahlukileyo, fumana impazamo, ufezekise into ngokulungiswa kwento, ubuyisele ukusebenza okuqhelekileyo kwemoto, xa impazamo yemoto ingajongwanga, thintela ukusetyenziswa kwe-hoist.

(3) ingxolo engaqhelekanga evela kwisinciphisi segiya, ukusilela kwesinciphisi segiya (njengesinciphisi okanye ukungabikho kwe-oyile yokuthambisa, igiya, ukunxitywa okanye ukonakaliswa komonakalo wokuthwala, njl. njl.), emva koko kufuneka kumiswe ukukhangela, kuqala kunqume isinciphisi okanye ukuthwala. Ngaphambi kokusetyenziswa ukuba i-oyile yokuthambisa, i-oyile iguquguquka rhoqo ekusebenziseni, njengokungabikho kokuthambisa, ngokuhambelana nemfuneko yokunciphisa ayiyi kuvelisa kuphela isandi esiphezulu se "buzzing", i-gear kunye nokuthwala ukugqithisa ngokugqithiseleyo okanye umonakalo.Abanye abantu bacinga ukuba umnciphisi okwethutyana yongeza okanye ukongeza ngokungaqhelekanga ioli yokuthambisa, isenokuthi iqhube, ayiyi kwenzeka ukungaphumeleli okukhulu, olu hlobo lwengcinga alulunganga.Inkampani yethu ifake i-hoist yombane, kuba abasebenzi balibale ukunciphisa ibhokisi yeoli yokuthambisa, kuphela usuku lovavanyo, i-reducer. kukhutshwa isandi esiphakamileyo kakhulu, vula ibhokisi yokunciphisa, yafumanisa ukuba i-gear ngenxa yokugqoka ngokugqithiseleyo kunye ne-scrap.I-Reducer ethwele umonakalo, efana nokungaphumeleli kwe-motor, iya kukhupha isandi esingaqhelekanga kufuphi ne-bearing.Ukuze uthintele ukwandiswaiphoso, nokuba ngaba i-reducer gear igugile ngokugqithiseleyo okanye yonakele, okanye i-reducer bear yonakalisiwe, kuyimfuneko ukudibanisa ngokukhawuleza, ukugqithisa okanye ukubuyisela, ukuphelisa iphoso kunye nokunciphisa ingxolo.

3. Xa uqhobosha, umgama wokutyibilika wexesha lokuphumla udlula iimfuno ezichaziweyo

Ukunyuswa kombane ngaphandle kwenkonzo ixesha elide, umntu ngempazamo ulungelelanisa i-nut yohlengahlengiso, okanye ukunxiba umsesane wokuqhaqheka kukhulu kakhulu, ukuze uxinzelelo lwe-brake spring luncitshiswe, amandla okuqhobosha ancitshiswe, xa ukuvalwa, ukunyathela akuthembekanga, umgama wokutyibilika udlula iimfuno ezichaziweyo, le meko logama nje ngokweemfuno zokunyuswa kwe-hoist, ukulungelelanisa i-nut ye-brake ingaba.Kodwa kufuneka sinikele ingqalelo kumsebenzi, ukuphakamisa izinto ezinzima, ukunqanda ukulungiswa, ukuhlolwa kunye nokugcinwa kwe-brake. Ngamanye amaxesha, lungisa i-nut ye-braking, yeka ukuwela umgama ongaphezulu kweemfuno ezimiselweyo, usadibana nemeko enjalo, qwalasela ezinye izizathu, i-ring yokuqala yokuqhawula i-brake yokuqala, khangela ukuba umphezulu we-brake kunye nongcoliseko lweoli, njengeoli, ukunciphisa ukukhuhlana. i-coefficient, inokwenza i-brake xa utyibilika, umgama owela ngaphezu kweemfuno ezimiselweyo, lungelelanisa nje i-nut ye-braking ayisebenzisi kakhulu, kwaye icoceke kuphela i-surf ye-brake.I-ace (ukucoca kulula ukusebenzisa i-benzine), buyisela i-coefficient ye-brake surface friction;Okwesibini, njengokukhulula iringi ye-brake okanye umonakalo, iringi ye-brake ayinakuqinisekisa ukuba i-brake iyasebenza, ibuyisela i-ring ye-brake kuphela; , kuphela umsesane ongalunganga wokudambisa umnxeba kunye nekhowuni yesigqubuthelo sesiphelo sangasemva, ibrake, ibrake surface contact, less braking force incinci kakhulu, ukuhla okungaphezulu kweemfuno ezimiselweyo, ukugcinwa kunye nokulungiswa, ukuze kunyuswe amandla okuqhobosha, kufuneka kufumaneke. indawo yoqhagamshelwano olungeluhle, ukugaya, ukwandisa indawo yokudibanisa xa uqhoqhoqho, ukusilela ukugawula, kufuneka kutshintshe izixhobo;Emva kokuyeka, uqhagamshelwano phakathi kwendandatho ye-brake kunye nekhoni yesigqubuthelo sokugqibela esingemva sibi okanye asikwazi ukudibanisa, ukwenzela ukuba i-brake effect ye-hoist ilungile okanye imbi.Kwiimeko ezinjalo, ukudibanisa kufuneka kulungiswe okanye kufakwe endaweni yayo.Ukongezelela, i-brake pressure spring ixesha elide ukuvelisa ukukhathala, ukwenzela ukuba i-spring force ibe yincinci, imise, i-brake ayiqini, kufuneka ubeke endaweni yasentwasahlobo, ulungelelanise. amandla okuqhobosha.

I-4, ukunyuka kobushushu bemoto kuphezulu kakhulu

Okokuqala, kufuneka sijonge ukuba i-hoist igcwele kakhulu.Ukulayisha ngaphezulu kuya kukhokelela ekufudumezweni kweemoto.Ukulayishwa kwexesha elide kuya kutshisa i-motor. Ukuba i-motor ayilayishwanga kwaye ishushu, khangela ukuba i-motor bear yonakalisiwe; izizathu zokufudumeza kwemoto.Xa usebenzisa, kufuneka ihambelane ngokungqongqo kunye nenkqubo yokusebenza yemoto.Xa i-motor isebenza, i-brake clearance incinci kakhulu, ayicimeki ngokupheleleyo, ibangele ukuxubana okukhulu, ukufudumeza kwe-friction ngexesha elifanayo lilingana ukwandisa umthwalo owongezelelweyo, ukwenzela ukuba isantya semoto sincitshiswe, i-current iba nkulu kunye nobushushu, ngeli xesha kufuneka liyeke ukusebenza, lungisa i-brake clearance.

5. Ukuba ubunzima bukhuphukela phakathi komoya, abukwazi ukuqaliswa kwakhona emva kokuyeka

Ukuhlalutya izizathu, jonga kuqala ukuba i-voltage yenkqubo iphantsi kakhulu okanye ingaba i-fluctuation inkulu kakhulu, kulo mzekelo, linda kuphela ukuba i-voltage ibuyele kwesiqhelo ngaphambi kokuba uqalise;Kwelinye icala, kufuneka sinikele ingqalelo kukusilela. yesigaba sokusebenza kwenqanaba lesithathu lemoto, elingenakuqaliswa emva kokuvalwa.Ngeli xesha, kufuneka sijonge inani lesigaba samandla.

I-6, ayinakumisa okanye kwisithuba somda ungayeki

Olu hlobo lwemeko ngokuqhelekileyo i-welding yoqhagamshelwano ye-contactor.Xa i-stop switch icinezelekile, umnxibelelwano woqhagamshelwano akakwazi ukunqanyulwa, i-motor inokusebenza njengesiqhelo, kwaye i-hoist ayiyeki.Ukuya kwisigxina somda, ukuba i-limiter ingaphandle komyalelo, i-hoist ayiyi kumisa. Kule meko, unqumle amandla ngokukhawuleza, ukwenzela ukuba i-gourd inyanzeliswe ukuyeka.Emva kokuyeka, lungisa umnxibelelwano okanye umda.Ukuba yonakele kakhulu kwaye ayinako ukulungiswa, kufuneka itshintshwe.

7. Isinciphisi sivuza ioli

Kukho izizathu ezibini zokuvuza kwe-oyile yokunciphisa:

(1) phakathi komzimba webhokisi yesinciphisi kunye nesigqubuthelo sebhokisi, indibano yeringi yokutywina ayilunganga okanye yonakele umonakalo, kufuneka isuswe ukuze kulungiswe okanye kubuyiselwe umsesane wokutywina;

(2) I-screw yokudibanisa yesinciphisi ayiqiniswanga.Emva kokumisa umatshini, i-screw kufuneka iqiniswe.

8. Izizathu zokutshayela injini zezi zilandelayo:

I-motor shaft ephethe i-ring ring ibaluleke kakhulu, i-rotor core displacement, okanye ngenxa yezinye izizathu zokwenza i-stator core displacement, okubangela ukuba i-motor cone rotor kunye ne-stator clearance incinci kakhulu, kwaye ukutshayela kwenzeka. "Ukutshayela" ngqongqo ngokungqongqo. kuthintelwe.Xa ukutshayela kwenzeka, ikhonkco elixhasayo kufuneka lisuswe ukutshintshwa, kwaye isithuba phakathi kwe-stator rotor cone kufuneka ilungiswe ukuze ifane, okanye ithunyelwe kwivenkile yokulungisa ukulungiswa.Ngohlalutyo lweempazamo eziqhelekileyo kunye nokunyangwa kwe-hoist yombane, ukuze abasebenzi bokugcinwa kwe-hoist bajongane neziphene, bazi apho baqale khona ukujonga, ukuphucula ukusebenza kakuhle kokugcinwa, ukongeza, kodwa kunye nomqhubi ukubonelela ngendlela yokujongana neengxaki kwisayithi.
