Imiphumela Yokuphatha Umkhakha Kwezindlela Zokugranula Amaphutha

Imiphumela Yokuphatha Umkhakha Kwezindlela Zokugranula Kwemithombo Yokuhanjiswa Kwamaphutha

Imiphumela yokuphatha umkhakha ephathelene ngqo nesikhundla somkhakha kuzindlela zokugranula kwemithombo yokuhanjiswa kwamaphutha. Izinto ezintathu zokubhekana ngokuphelele—isimo samaphathi, amaphoyisa okuphatha umkhakha, nemithombo yokuphatha umkhakha wokuhamba—iyasebenza ngokuhlanganisa ukuwakha indawo yokuproduka engenakho umkhakha futhi enobuhle.

Amaphathi Ama-V-Cut Nokuphatha Umkhakha Kwesimo Sokugranula

Ama-rotor asikwa nge-V athatha indawo yezinhlamvu eziqondile ngephrofayili yokusika enama-engeli, efana nesikabha esika ipulasitiki kancane kancane kulo lonke ubude bokubala esikhundleni sokuyichoboza ngesikhathi esisodwa. Lokhu kusakaza amandla okusika phezu kwe-arc ende, kuguqula ukuqhuma kwemvamisa ephezulu kube ukubhonga okubushelelezi, okuphansi futhi kunciphise kakhulu amandla omsindo we-peak ikakhulukazi ngesikhathi sokuxhumana kokuqala kwezinto. Ama-rotor aqondile avamile akhiqiza imisindo enamandla, eshaya ngamandla ngoba wonke ama-blade asebenza ngesikhathi esisodwa. Isivinini se-rotor kanye nokukhululeka kommese kuqondiswe kahle ukuze kuhambisane nobulukhuni bendaba: ukunciphisa igebe lokusika kunciphisa ukushaywa, okuwumthombo oyinhloko womsindo womoya. Lezi zinguquko zibhekana nomthombo wengqikithi yomsindo we-granulator, ngokuvamile ukwehlisa amazinga okucindezela umsindo emthonjeni ngaphandle kokuphazamisa ukusebenza kahle.

Izakhiwo Ezingenawo Umsindo Nezakhiwo Ezivalekile Ezinamakhasi Amabili

Izindlu ezakhiwe kahle zivimbela umsindo osemoyeni ngaphambi kokuba ufike endaweni yomqhubi. Isakhiwo esihlukaniswe kabili sisebenzisa igobolondo elingaphandle eliqinilengokuvamile elihlanganisa ama-vinyl noma ama-composite panels agcwele kakhulunokufakwa kwangaphakathi kwensimbi okugoqiwe, okuhlukaniswe ungqimba oluqinile lokumunca njengenhlaka evulekile ye-acoustic noma uboya bam Lesi sithiyo esiphakathi kwezinto eziphilayo nemimoya sivimbela futhi sichithe amandla omsindo ngempumelelo. Izinsimbi eziqinile zihlukanisa izingqimba ukuze zivimbele ukudlidliza, kuyilapho iminyango yokufinyelela nezindawo zokuphakelayo zinama-gasket kazibuthe nama-hinges asebenza kanzima ukuze kulondolozwe ubuqotho be-acoustic. Uma ifakwe kahle, izindlu ezinjalo zifinyelela ku-1015 dB ((A) ukunciphisa umsindookusekela ukuhambisana nomkhawulo wokubonakaliswa kwehora le-8 we-OSHA.

Izakhiwo Ezikhuthaza Ukudlidliza Nezinhlelo Zokuhlela Izikhala

Ukudlula kwezinkinga zokudlula kwenza isiphambano esikhulu kumkhakha wokugcina umbono, nakuba ukugcina umbono wokuphuma kwamaphutha ayagcinwa. Isikhumba esisodwa nesikhumba sesikhwama esisodwa noma izinkukhamba zokuhlukanisa zisondela igranulator kusuka kwenyanga, kubhekisa ukudlula kwezinkinga zokudlula kwezinyawo ezincane kusuka kwenyanga kusuka kwezindawo zokugcina. Izinkukhamba zihlelwa ngokuzimela ngokuchaza kwezinkinga zokusebenza nokubheka ukubheka kwezinkinga zokusebenza. Isimo sokuhlela isikhumba sokufaka sifuna ukugcina umbono ngokucima ukudlula kwezinkinga ngokucima ukudlula kwezinkinga zokudlula: izibhambo ezithunywa ngokubhala zisondela ukungabheki ukuthi izicelo zizobhala futhi zidla izinkinga zokudlula, ngakho-ke ukulawula okuphelele kokufaka kusondela ukugcina ukudlula kwezinkinga zokudlula okuyizinkinga zokudlula kwezinkinga zokudlula. Ngokuhlanganisa lezi zinto, zisondela ukudlula kwezinkinga zokudlula, zihlela ubomi bokushaya, futhi zilahlela izikhathi zokulungisa.

Izindlela zokusebenza zokuhlenga ukugcina umbono omncane kwezinkulungwane zokugcina izicelo zokuvutha

Ukuqinisekisa ukuthi izingxenye zizokhala ngempela kuzokwenzeka ngokuphelele kokusebenza—akukho kufanele ukuthi kwenziwe kuphela kuqala. Izindlela ezimbili ezenziwa ngokwesibonelo—ukulawula ukudlula nokuhlenga ngaphambi kwemiphumela—zihlanganisa ukuthi izindlela zokukhala ziyakhiwa ngaphezu kwe-80 dB(A) ngokuphelele, ngakho kuyakhiwa ukuthi izinto ziyasebenza ngokuphelele nokuthi izinto ziyakhiwa ngokuphelele.

Izindlela Zokudlula Ngokuchangeka Kwesikhathi (VFDs) Ukulawula Ukuvulwa Kwesikhathi Sokubuka Nokuthi Kungaphezulu Kwe-80 dB

Amadriveri we-Frequency ephindaphindayo (VFDs) ayasebenza ngokuphinda-phinda kwezinyathelo zokusebenza kwe-rotor ukufakela kwezinhlobo zezinto ezihlukene, okunqamuka ukuthi amotori esixhenxe esikhulu ayisebenzi ngokusha kakhulu noma kusenziwa ngokusha okuncane. Ngokuhlola kwesikhumba ngo-2023, ukubuyisela isikhumba ngokuqondisa i-VFD yasimula umlinganiselo wokusha kusuka ku-86 dB(A) ku-78 dB(A) emeteru eyodwa ngokucatshulwa kokusha kwe-rotor ngemizindo engezansi. Amadriveri we-Frequency ephindaphindayo ayenze kube khona ukususa ngokusha okuncane okungabonakala ngokusha okuphelele—okuyi mthombo wokusha okuphambili okwenza ukusha okuphambili okungabonakala ngokusha okuphambili. Ukuphawula i-driveri ukusebenza kuphela ngokusha okuncane okudingekayo ukukhupha ngokucacileyo kungavimba ukuthi kubhekene nezinhlobo zokusha nokusha okungabonakala ngokusha okuphambili, okugcina isikhumba ngaphakathi kwesilinganiso se-OSHA se-85 dB(A) sokusebenza futhi ngaphakathi kwesilinganiso se-Directive ye-EU 2003/10/EC yokusebenza okuncane—ngokukhupha umsebenzi wokusebenzisa amandla ngokuphakeme ku-15%, ngokwesilinganiso Isilinganiso Sezinkambo Zokusebenza Ngokuvamile 2024 .

Ukuvamisa Ngokuvamile: Ukubalansisa Amakhnife, Ukulayisha Amabhiringi, Futhi Ukujabula Okuphambili

Umbuzo often wabonisa ubuncane beqiniso lezinhlobo zokusebenza. Amakhnife angakwazi ukubalwa kuyenza ukuthi i-rotor ibe yisikhathi, kuyathumela ukuthwasha kusuka ku-frame futhi kuyaphuma umsindo wokugcina okuphansi. Ukubalwa kwesikhathi se-rotor ngokuphathelene nesikhathi sokusebenza ngamahora angu-500 kuyasimela ukubalwa okungafanele ngapansi kwe-0.5 g·mm/kg—lokhu kukhona kubona ukuthi kuyasebenza ngokuthi kuvalelwe ukuthwasha ngokuphansi kwe-6–8 dB(A), ngokwesiqephu sika Machinery Health Institute 2023 . Ubunzima bezinkambo zokusebenza kuyisikhundla esifanayo: izinkambo ezingazangeleki noma ezinomphakathi ziyagcina futhi ziyakhulisa ukuthwasha kwesithembiso. Isimo sokufaka amafutha ngokuphathelene nesikhathi esihlanganisiwe ngothando nokukhangela izinkambo ngokusebenzisa isono sokusebenza kuyasibonisa ukuthi kuyadala kabusha. Ngokufanayo, ukukhangela ukuthwasa kwamashini nezinye zezinye zokusebenza kuyasimela ukuthi kungabi “ukuchitha okwamanzi”—izikhumba ezingavali ziyathwasa emva kokuthi ziyachitha. Idatha yokuqonda kusuka kumkhiqizo omkhulu wabonisa ukuthi ukubuyisa izikhumba ngokuthi kubuyiselwe ngokuthi kuthwasa kwezinye zokusebenza kwe-0.3 mm (ngokulinganisa ne-0.5 mm) kuyavalela ukuthwasha okuphezulu ngokuphansi kwe-40% ngeminyaka miyeni.

Isimo Sokuvumela: Izivumo Zokuthwasha Nezivumo Zokuvumela Kwamakhithi Okuthwasa Kwamaphutha

I-OSHA 29 CFR 1910.95 kanye ne-EU Directive 2003/10/EC Izidingo ezikude nge-1 Meter

Imikhawulo yokuchayeka komsindo emsebenzini yamayunithi okugaya kabusha amapulasitiki ichazwe yi-OSHA 29 CFR 1910.95 kanye ne-EU Directive 2003/10/EC. I-OSHA ibeka umkhawulo ovumelekile wokukhishwa kwe-90 dB ((A) ngokwesilinganiso esiphakanyisiwe sesikhathi samahora angu-8, ngesilinganiso sokushintshana esingu-5 dB. Umyalelo we-EU ubeka amanani aphansi aphezulu okusebenza okuchayeka ku-80 dB (A) naku-85 dB (A), ngokulandelana, futhi ukhawulela ingcindezi yomsindo ephezulu ku-135 dB (C). Ngenxa yokuthi ama-granulator ngokuvamile akhipha u-90100 dB (((A) kumitha elilodwa, ukulawula okuphathelene nokuphatha kukodwa akuvamile ukuba kwanele. Izingxenye zobunjiniyelakuhlanganise nezindlu ezivalelwe ngomsindo kanye nemiklamo ecindezelwa ukudlidlizaziyadingeka ukuze kufinyelelwe ezingeni eliphansi lokuchayeka komqhubi ngaphansi kwemingcele yemithetho. Ngaphandle kwazo, izakhiwo zingaba sengozini yokuqalisa izinhlelo zokulondolozwa kokuzwa okuyimpoqo, okwandisa izindleko zokulandela imithetho nezingozi zempilo yabasebenzi.

Amaphrothokholi wokulinganisa ensimini kanye nendlela yokuqinisekisa umsindo yokuvuselela

Ukuqondisa okuphelele kufolowula ISO 11202, okwakho kusisombululo sokubhala ngemitha e-1 emaphakathi kwezindawo zokusebenza kwemashini, ngokusebenzisa isound level meter esibhalwe ngokuphelele (Class 1) esihleli kumkhosi wokusebenza. Isivinini sokushaya kwe-A-weighted (LAeq) sibhalwa ngokugcina ukusebenza kwesikhathi esifanayo. Emva kokwenza ukuguqula—njengokufaka i-V-cut rotor noma isikhumba sesilayidi ezimbili—ukuthi kufanana nokufunda kufanana kufundwa futhi ukuqondisa ukuthi kungabi nesixhaphakade sokushaya. Ukugcina okuvumelekile kufanele kubonise ukuthi ukushaya kuyasebenza ngokuphambili ≤80 dB(A) ngokusebenza ngokuzimisa, kubonisa ukuthi kufanele kubhekwe ngokuphambili kwezindlela zokusebenza okubi futhi kubonisa ukuthi izinhlelo zokusebenza ziyasebenza ngendlela efanele.

Imibuzo eyadluliselwe ngokusebenza kwe-acoustic emaqhingithini we-plastic recycling granulation

Kungani i-V-cut rotors ziyinkulu kunezikhova zokuphambuka?

I-V-cut rotors zihlanya i-plastic ngokuphambuka kwezinyathelo zokuhlanya, kunciphisa ukushaya okuphakeme kwe-high-frequency futhi kunciphisa isixhaphakade sokushaya ngokulinganayo kwezikhova zokuphambuka, okuzoba nomsho omkhulu wokushaya okuphambuka.

Izikhumba zokuvikela ukushaya ziyasebenza njani?

Izindlu ezivikelwe ngomsindo ezakhiwe kahle zingafinyelela ekunciphiseni umsindo ongu-1015 dB (((A) ngokuvimba umsindo osemoyeni nokusabalalisa amandla ezindaweni eziningi zemvamisa.

Iyiphi indima egcinwayo yokugcinwa kokuphepha ekunciphiseni umsindo?

Ukugcinwa okuvimbelayo, njengokulinganisela ngommese, ukugaya ama-bearing, nokuqapha ukugqoka, kuvimbela ukungalingani kwemishini, kunciphise izinga lomsindo ngokubheka izimbangela eziyinhloko zokugqama nokudlidliza kwesakhiwo.

Ama-VFD asekela kanjani ukuhambisana namazinga omsindo?

Ama-VFD avumela ukulawulwa kwejubane le-rotor kanye nezindawo zokuqalisa okuthambile, ukunciphisa umsindo ngokunciphisa amajubane emoto ngezikhathi zokukhipha okuphansi nokuvimbela ukuphazamiseka kwe-blade, ukuqinisekisa ukuhambisana nemithetho ye-OSHA ne-EU yomsindo.

Iyini i-ISO 11202, futhi kungani ibalulekile?

I-ISO 11202 icacisa izivumelwano zokulinganisa ngokunembile izinga lomsindo kumamitha angu-1 kusetshenziswa amamitha wezinga lomsindo, okuqinisekisa ukuqinisekiswa okuthembekile kokuhambisana nokungenelela kobuchwepheshe.
