Izimbangela nezixazululo zokwehluleka kwe-electric hoist

1. Cindezela inkinobho yokuqalisa futhi i-hoist kagesi ayisebenzi

Ngokuyinhloko kungenxa yokuthi i-hoist ayixhunyiwe ku-voltage yokusebenza elinganiselwe, futhi ayikwazi ukusebenza.Ngokuvamile, kunezimo ezintathu:

(1) ukuthi uhlelo lokuphakelwa kukagesi luwukunikeza amandla okuphakelwa kukagesi kwesixhumi sikagesi, ngokuvamile lisebenzisa ipeni lokuhlola ukuhlola, njengokungabi khona kukagesi, bese lusebenza ngemva kokuphakelwa kukagesi;(2) umgogodla kanye neluphu yokulawula izinto zikagesi , ukunqanyulwa kwesifunda noma ukuthintana okungalungile, futhi kungenza i-hoist motor ingakwazi ugesi, ivele lolu hlobo lwesimo, idinga ukulungisa okuyinhloko, isekethe yokulawula, ukugcinwa nokulungiswa, ukuze kuvinjwe amasekhethi amakhulu nokulawula ukuya esigabeni sesithathu. Isigaba samandla emoto nokushiswa, noma ukuphakamisa ukusebenza kukagesi, ngokuzumayo, kuzomele kuphakamise injini isuka entanjeni yamandla ukuze inqamule emgwaqeni, ukuze ikwazi ukulawula nokulawula ukuhanjiswa kukagesi, bese uchofoza inkinobho yokuqala nokumisa, hlola ukuhlaziya nokulawula. isimo sokusebenza sesekethe kagesi, ukuba nenkinga amathuluzi kagesi noma izintambo zokukhandwa noma ukushintshwa, lapho kuqinisekisa isekethe eyinhloko nokulawula okungenayo inkinga, ukusetha kabusha ukuhlola;(3) kune-voltage elinganiselwe yamandla e-hoist motorwn ngaphezu kwe-10%, i-torque yokuqala ye-motor incane kakhulu, yenza izinto zokuphakamisa i-hoist, futhi ayikwazi ukusebenza, hlola i-voltage yokufaka ye-motor ilinganiswa ne-multimeter noma i-voltmeter, njll, ngenxa yokuthi i-voltage iphansi kakhulu, ngempela ukwenza i-motor ayikwazi ukuqala, izobuyela kwesistimu kagesi kokujwayelekile ngaphambi kokusetshenziswa kwe-hoist kagesi.Kwesinye isikhathi, i-voltage ye-gourd motor ijwayelekile, futhi i-gourd ayisebenzi, okudingeka kucatshangelwe ngezinye izizathu, njenge: I-motor iyasha, injini idinga ukushintshwa uma ilungiswa; I-Calabash ayisetshenziswa isikhathi eside, ukunganakeki kahle nezinye izizathu ukuze isondo lebhuleki kanye ne-end cover kugqwale, ukuqala i-brake wheel off hhayi ukuvula, Injini ikhiphe umsindo othi “hum” kuphela, ayikwazi ukukhuphuka, igula alikwazi ukusebenza.Ngalesi sikhathi, kufanele isuse isondo lokubhuleka, ihlanze indawo egqwalile, bese ihlola kabusha; Uma injini ishanelwe kabi, izokwenza ungaphenduki.Uma lesi simo sitholakala, kufanele simiswe, futhi injini kufanele ilungiswe noma ishintshwe ukuze kuqinisekiswe ukusebenza okuvamile kwe-hoist.Ngaphezu kwalokho, ukusetshenziswa kwe-electric hoist overload kuvinjelwe ngokuqinile ekukhiqizeni.Lapho izimpahla zigcwele ngokweqile, i-hoist ayizihambisi izimpahla, injini yenza kuphela umsindo othi "hum", futhi ayisebenzi.Uma ibucayi, injini izoshiswa, futhi idale nengozi.

2. Umsindo ongavamile uvela lapho i-hoist kagesi isebenza

I-electric hoist inkathazo enkulu, isibonelo, ukulawulwa kwezinto zikagesi, i-motor kanye ne-reducer, njll kwavela iphutha, kuvame ukuhambisana nomsindo ongavamile, umsindo wesikhundla nokuphakama futhi awunawo umehluko, nesizathu inkinga ekunakekeleni okuhlukene, bafuna ukulalela ukuze babone okwengeziwe, bangakwazi ukusebenzisa, noma ngokusho kwezici zephutha zomsindo, banqume indawo yomsindo, befuna futhi balungise.

(1) Umsindo ongajwayelekile uvela endaweni yokulawula futhi wenze umsindo othi “hum”.Ngokuvamile kubangelwa ukwehluleka kokuthintana (njengokuthintana kabi kwesixhumi se-AC, ukungafani kwezinga le-voltage, ukunamathela komgogodla kazibuthe, njll.).I-contactor yephutha kufanele iqondiswe futhi ishintshwe uma ingakwazi ukwenganyelwa.

Umsindo ongajwayelekile, (2) injini, kufanele ime ngokushesha, uhlole ukuthi injini isebenza ngesigaba esisodwa, noma inomonakalo, i-coupling axis ayiqondile, futhi igumbi “lishanele”, lezi zizokwenza umshini ube nomsindo ongajwayelekile, umsindo. yendawo yephutha ehlukene kanye nephezulu nephansi futhi ayizwakali ngendlela ehlukile, ukusebenza kwesigaba esisodwa, injini evela kumsindo ovamile oqinile nobuthakathaka "wobhuza". ” umsindo “we-stomp – stomp”;Lapho iphini lokuhlanganisa lingalungile, noma injini ishanelwe kancane, yonke injini ikhipha umsindo “obhuqayo” ophakeme kakhulu, ongahlali uhambisana nomsindo ohlabayo futhi onokhahlo. Ngamafuphi, ngokusho komsindo ohlukile, thola iphutha, wenze into ngesondlo, ubuyisele ukusebenza okujwayelekile kwemoto, lapho iphutha lemoto lingabhekwana nalo, vimbela ukusetshenziswa kwe-hoist.

(3) umsindo ongavamile ovela kusinciphisi segiya, ukwehluleka kwesinciphisi segiya (njengesinciphisi noma ukungabi khona kwe-oyela yokuthambisa, igiya, ukuguga noma ukulimala komonakalo okhona, njll.), khona-ke kufanele kumiswe ukuhlola, kuqala kunqume isinciphisi noma isithako. ngaphambi kokusetshenziswa uma uwoyela wokugcoba, uwoyela ushintsha njalo lapho kusetshenziswa, njengokuthi akukho lubrication, ngokusho kokunciphisa imfuneko ngeke nje kukhiqize umsindo ophezulu "obhubhuzayo", igiya kanye nokuthwala ukuguga ngokweqile noma ukulimala.Abanye abantu bacabanga ukuthi i-reducer ayikwenzi okwesikhashana. engeza noma engeza ngokunganaki amafutha okugcoba, namanje angasebenza, ngeke kwenzeke ukwehluleka okukhulu, lolu hlobo lomcabango alulungile.Inkampani yethu yafaka i-hoist kagesi, ngoba abasebenzi bakhohlwe ukunciphisa ibhokisi lamafutha okugcoba, kuphela usuku lwesivivinyo, isinciphisi. ikhishwa umsindo ophakeme kakhulu, vula ibhokisi lokunciphisa, ithole ukuthi igiya ngenxa yokuguga ngokweqile nokulahlwa. Ukulimala okuthwala i-Reducer, okufana nokuhluleka kwe-motor bearing, kuzophinde kukhiphe umsindo ongavamile eduze ne-bearing.Ukuze kuvinjelwe ukwandaiphutha, kungakhathaliseki ukuthi i-reducer gear igqoke ngokweqile noma ilimele, noma i-reducer bear yonakalisiwe, kuyadingeka ukuhlakaza ngokushesha, ukulungisa kabusha noma ukufaka esikhundleni, ukuqeda iphutha nokunciphisa umsindo.

3. Lapho ubhuleka, ibanga lokuslayida lesikhathi sokuphumula lidlula izidingo ezishiwo

I-electric hoist ingasebenzi isikhathi eside, othile ulungise iphutha lokulungiswa kwe-brake nut, noma ukugqokwa kwendandatho yebhuleki kukhulu kakhulu, ukuze umfutho we-brake spring unciphise, amandla okubhuleka ayancipha, lapho ukuvala shaqa, ukubhuleka kungathembeki, ibanga lokushelela lidlula izidingo ezishiwo, lesi simo inqobo nje uma ngokwezidingo zokucaciswa kwe-hoist, lungisa i-brake nut can be.Kodwa kufanele sinake umsebenzi, siphakamise izinto ezisindayo, sivimbele ukulungiswa, ukuhlolwa nokugcinwa kwe-brake. Ngezinye izikhathi, lungisa i-braking nut, yeka ukuwela ibanga elingaphezu kwezidingo ezinqunyiwe, usahlangabezana nesimo esinjalo, cabangela ezinye izimbangela, qala ngokuvula indandatho yokubhuleka kuqala, hlola ukuthi indawo yokubhuleka enokungcoliswa kwamafutha, njengamafutha, inciphisa ukungqubuzana. i-coefficient, ingenza ibhuleki lapho islayida, ibanga eliwayo ngaphezu kwezidingo ezinqunyiwe, vele ulungise nati lokubhuleka alisetshenziswa kakhulu, futhi i-surf ye-brake ehlanzekile kuphelai-ace (ukuhlanza kulula ukusebenzisa i-benzine), buyisela i-coefficient ye-brake surface friction;Okwesibili, njengokuxegiswa kweringi yebhuleki noma umonakalo, iringi yebhuleki ayikwazi ukuqinisekisa ukubhuleka okusebenzayo, ibuyisela iringi yebhuleki kuphela; , indandatho yokudambisa engcolile kuphela kanye nekhoni yekhava yangemuva, ibhuleki, indawo yokuxhumana yebhuleki, amandla amancane okubhuleka mancane kakhulu, ukwehla okungaphezu kwezimfuneko ezinqunyiwe, ukugcinwa nokulungiswa, ukuze kwandiswe amandla okubhuleka, kufanele uthole. ukuma kokuthinta kabi, ukugaya, ukwandisa indawo yokuxhumana lapho ubhuleka, yehluleka ukugaya, idinga ukushintshwa kwezesekeli;Ukuhlangana kwe-hoist motor akunyakazi kahle noma kubambeke.Ngemva kokuma, ukuxhumana phakathi kweringi yebhuleki kanye nekhoni yesembozo sokuphela kwangemuva kubi noma akukwazi ukuthintana, ukuze umphumela wokubhuleka we-hoist ube muhle noma mubi.Ezimweni ezinjalo, ukuhlanganisa kufanele kulungiswe noma kushintshwe.Ngaphezu kwalokho, i-brake pressure spring ikhiqiza isikhathi eside ukuze ikhiqize ukukhathala, ukuze amandla entwasahlobo abe amancane, ayeke, i-brake ayiqini, kufanele ubeke esikhundleni sentwasahlobo, ulungise kabusha. amandla okubhuleka.

4, izinga lokushisa lemoto liphezulu kakhulu

Okokuqala, kufanele sihlole ukuthi i-hoist igcwele ngokweqile.Ukulayisha ngokweqile kuzoholela ekushiseni kwemoto.Ukulayishwa ngokweqile kwesikhathi eside kuzoyishisa injini. Uma injini ingalayishiwe ngokweqile futhi isashisa, hlola ukuthi i-motor bear yonakalisiwe yini; Kuyadingeka futhi ukuhlola ukuthi ingabe injini isebenza ngokuhambisana nesistimu yokusebenza enqunyiwe, engomunye izizathu zokushisisa kwemoto.Uma usebenzisa, kufanele ihambisane ngokuqinile nesistimu yokusebenza ye-motor.Lapho i-motor isebenza, imvume ye-brake incane kakhulu, ayicishiwe ngokuphelele, okubangela ukungqubuzana okuningi, ukushisa kwe-friction ngesikhathi esifanayo kulingana ukwandisa umthwalo owengeziwe, ukuze ijubane lemoto lincishiswe, okwamanje libe likhulu futhi ukushisa, ngalesi sikhathi kufanele kuyeke ukusebenza, lungisa imvume ye-brake.

5. Uma isisindo sikhuphukela phakathi komoya, asikwazi ukuqaliswa futhi ngemva kokuma

Ukuze uhlaziye izizathu, qala uhlole ukuthi i-voltage yesistimu iphansi kakhulu noma ukuthi ukushintshashintsha kukhulu kakhulu, kulokhu, linda kuphela ukuthi i-voltage ibuyele kokujwayelekile ngaphambi kokuqala; Ngakolunye uhlangothi, kufanele sinake ukuntuleka. yesigaba ekusebenzeni kwenjini yezigaba ezintathu, engakwazi ukuqalwa ngemuva kokuvalwa.Ngalesi sikhathi, sidinga ukuhlola inombolo yesigaba samandla.

6, akakwazi ukuyeka noma isikhundla umkhawulo namanje ungayeki

Lolu hlobo lwesimo ngokuvamile luyi-welding yokuxhumana ye-contactor.Lapho umshini wokumisa ucindezelwa, othintana naye othintana naye akakwazi ukunqanyulwa, i-motor ingasebenza njengenjwayelo, futhi i-hoist ayimi.Esikhundleni somkhawulo, uma i-limiter ingasebenzi, i-hoist ngeke ime. Kulesi simo, nqamula amandla ngokushesha, ukuze i-gourd iphoqeleke ukuyeka.Ngemva kokumisa, lungisa i-contactor noma i-limiter.Uma yonakele kakhulu futhi ingenakulungiseka, kufanele ishintshwe.

7. Isinciphisi sivuza amafutha

Kunezizathu ezimbili zokuvuza kukawoyela we-reducer:

(1) phakathi kwebhokisi lesinciphisi nesembozo sebhokisi, ukuhlanganiswa kwendandatho yokuvala akubi kahle noma kubhuntshile umonakalo, kufanele kususwe ukuze kulungiswe noma kushintshwe iringi yokuvala;

(2) Isikulufu sokuxhuma sesinciphisi asiqiniswa.Ngemuva kokumisa umshini, isikulufu kufanele siqiniswe.

8. Izizathu zokushanela injini yilezi ezilandelayo:

I-motor shaft ephethe indandatho ibucayi, ukugudluka kwe-rotor core, noma ngenxa yezinye izizathu zokwenza umgogodla we-stator ugudluke, okuholela ekutheni i-motor cone rotor kanye ne-stator clearance kuncane kakhulu, futhi ukushanela kwenzeka. "Ukushanela" kwemoto kuqinile. kwenqatshelwe.Lapho ukushanela kwenzeka, indandatho esekelayo kufanele isuswe ukuze ifakwe esikhundleni, futhi igebe phakathi kwe-stator rotor cone kufanele ilungiswe ukuze ifane, noma ithunyelwe esitolo sokulungisa ukuze ilungiswe.Ngokuhlaziywa kwamaphutha avamile kanye nokwelashwa kwe-hoist kagesi, ukuze izisebenzi zokugcinwa kwe-hoist zibhekane namaphutha, zazi ukuthi zizoqala kuphi ukuhlola, zithuthukise ukusebenza kahle kwesondlo, ngaphezu kwalokho, kodwa futhi ukuze opharetha anikeze indlela yokubhekana nezinkinga esizeni.
