Imigangatho yoKhetho lweeRoller Chains kwi-Agricultural Harvesters

Imigangatho yoKhetho lweeRoller Chains kwi-Agricultural Harvesters

Njengenxalenye ephambili edibanisa ukuhanjiswa kwamandla kunye nokusebenza komatshini wokuvuna, ukukhethwa kwekhonkco le-roller kumisela ngokuthe ngqo ukusebenza kakuhle kwesixhobo, izinga lokusilela, kunye nobomi benkonzo. Kubathengisi abajolise kwimarike yehlabathi, ukuqonda imigangatho yokukhetha yesayensi akuvumeli kuphela ukuhambelana ngokuchanekileyo kweemfuno zabathengi kodwa kunciphisa iindleko emva kokuthengisa kwaye kwakha udumo lobungcali-ingakumbi kwiimeko ezibalulekileyo zemveliso yezolimo apho "ixesha libaluleke kakhulu." Ukukhetha okukodwa okungalunganga kunokukhokelela ekuvuneni okupheleleyo komthengi, ekugqibeleni kuchaphazele ukuthembana kunye nentsebenziswano. Eli nqaku liza kuqala kwiimpawu zokusebenza kwabavuni, ukwahlukanisa ubungakanani obuphambili, amanyathelo asebenzayo, kunye neembono eziphosakeleyo eziqhelekileyoikhonkco lerolaukukhetha, ukubonelela abathengisi ngesikhokelo sobugcisa esisebenzayo.

I. Iiparameters Zokusebenza Kwe-Core Harvester Ekufuneka Zicaciswe Ngaphambi Kokukhetha

Indawo yokusebenza kwezixhobo zokuvuna zezolimo iyinkimbinkimbi kwaye iyaguquguquka. Izityalo ezahlukeneyo (ingqolowa, umbona, irayisi), ubukhali bokusebenza (indawo yokusebenza yemihla ngemihla ngomatshini ngamnye), kunye nemozulu yengingqi (imvula, uthuli, ubushushu obuphezulu) zonke zichaphazela kakhulu iimfuno zokusebenza kwekhonkco le-roller. Ngaphambi kokukhetha, kufuneka kuqinisekiswe iiparameter ezintathu eziphambili kunye nomthengi ukuze kuthintelwe "ukukhetha ngokusekelwe kumava."

Umthwalo Wokwenyani Ohanjiswayo: Kubalulekile ukwahlula phakathi "komthwalo olinganisiweyo" kunye "nomthwalo wempembelelo." Ngexesha lokusebenza kwe-harvester, iimeko ezifana ne-header edibana nezinto ezinzima (amatye, iziqwenga zokhula) okanye ukuqina kwekhonkco lokuhambisa ngequbuliso kunokuvelisa impembelelo ephindwe kabini ukuya kathathu kumthwalo olinganisiweyo. Ke ngoko, ukhetho lwemodeli kufuneka lusekelwe kumthwalo wempembelelo, kungekuphela nje kumthwalo ohambelana namandla alinganisiweyo achazwe kwincwadi yemiyalelo yezixhobo.

Isantya sokuSebenza kweTyathanga: Isantya sezinto ezahlukeneyo siyahluka kakhulu. Umzekelo, ityathanga lokuqhuba i-harvester header lidla ngokusebenza kwi-500-800 r/min, ngelixa isantya setyathanga lenkqubo yokuthutha ikakhulu si-200-400 r/min. Isantya esiphezulu sibangela amandla akhawulezayo e-centrifugal kunye nokuguguleka kwetyathanga; ke ngoko, iimodeli zetyathanga ezichanekileyo nezikhaphukhaphu kufuneka zibekwe phambili.

Iimpawu zeNdawo yokuSebenza: Kuqwalaselwa imilinganiselo emithathu ephambili: uthuli (umz., ukuvunwa kwengqolowa kwimimandla esemantla), ukufuma okuphezulu (umz., amasimi erayisi kwimimandla esemazantsi), kunye nokuba khona kwezinto ezirhabaxa (umz., incindi evela kwingca etyumkileyo kwizixhobo zokuvuna ezidibeneyo). Iindawo ezilukhuni zibeka iimfuno eziphezulu kwizinto zetyathanga, unyango lomphezulu, kunye nolwakhiwo lokutywina. II. Imigangatho emine ephambili yokukhetha iiRoller Chains zeZolimo

Ngokusekelwe kwiiparameter zokusebenza ezingentla, abathengisi banokunciphisa kancinci uluhlu lokukhetha besebenzisa le migangatho mine ilandelayo ukuze ekugqibeleni bagqibe imodeli efanelekileyo yetyathanga le-roller.

1. Ukuthelekisa Umthwalo: "Into yoKhuseleko" njengeSikhombisi esiPhambili

Umthwalo sisiseko esiphambili sokukhetha. Umba wokhuseleko kufuneka ubalwe ngokuthi “umthwalo wempembelelo yokwenyani ÷ umthwalo oguquguqukayo wetyathanga” ukuqinisekisa ukuba itsheyini ayiphuki phantsi kweemeko zokusebenza ezinzima.

Umgaqo weXabiso loKhuseleko: Kubavuni bengqolowa/irayisi, kucetyiswa ukhuseleko oluyi-≥1.8; kubavuni bombona (abanomthwalo omkhulu weengca), kucetyiswa u-≥2.2. Ukuba amandla omsebenzi womthengi aphezulu (umz., ngaphezulu kweeyure ezili-12 zokusebenza ngosuku), kufuneka anyuswe ngo-0.3-0.5.

Amanyathelo okhuseleko: Kuphephe "ukukhetha umthwalo omninzi" (oko kukuthi, into yokhuseleko ephezulu kakhulu), kungenjalo kuya kunyusa ubunzima betsheyini kunye neendleko, kwaye kunokukhokelela ekungadibani kakuhle kwetsheyini kunye ne-sprocket, okubangela ukuba itshixeke ngokukhawuleza.

2. Ukuhambelana kwesantya: Iimfuno zokuLungelelanisa iTyeya kunye nokuLungisa

Isantya sichaphazela ngokuthe ngqo ukuveliswa kobushushu kunye nesantya sokuguguleka kwetsheyini. Umgangatho wokuchaneka kwetsheyini kunye nesisombululo sokuthambisa kufuneka zikhethwe ngokusekelwe kwisantya.

Umgangatho Ochanekileyo: Kwizantya ezingaphezulu kwe-600 r/min, beka phambili iitsheyini ze-ISO 60 (ezichanekileyo kakhulu) ukunciphisa ukungcangcazela kunye nengxolo ngexesha lokusebenza; kwizantya ezingaphezulu kwe-400 r/min, iitsheyini ze-ISO 80 (ezichanekileyo eziqhelekileyo) zinokukhethwa ukuze kulinganiswe iindleko kunye nokusebenza.

Ubudlelwane bokuthambisa: Iitsheyini ezikhawulezayo zifuna igrisi echasene nokuguguleka eshushu kakhulu (njengegrisi esekwe kwi-lithium), kwaye abathengi kufuneka bacetyiswe ukuba banciphise umjikelo wokuthambisa (yizalisa rhoqo emva kweeyure ezisi-8) ukuze baphephe "ukungqubana okomileyo" ngenxa yokuthambisa okunganelanga.

3. Ukulungelelaniswa kokusingqongileyo: Ukukhethwa kwezinto kunye noNyango loMphezulu
Iindawo ezahlukeneyo zokusebenza zifuna ukukhethwa okujoliswe kuzo kwezinto zetsheyini kunye neenkqubo zonyango lomphezulu, nto leyo echaza ngokuthe ngqo ukugqwala kwetsheyini kunye nokumelana nongcoliseko.

Indawo yokusebenza | Izinto ezicetyiswayo | Inkqubo yoNyango lomphezulu | Iingenelo eziphambili

Indawo enothuli, eyomileyo | Intsimbi yoLwakhiwo lwe-40MnB Alloy | I-Carburizing kunye ne-Cenching + i-Phosphating | Ubulukhuni obuphezulu bomphezulu, obumelana nothuli kunye nokuguguleka

Umswakama ophezulu, Indawo enemvula | 304 Intsimbi Engagqwaliyo (Umthwalo Olula) | Unyango Lokutshayela Umoya | Ukuthintela ukugqwala okunamandla, okufanelekileyo kwimisebenzi yasemasimini erayisi

Umthwalo Onzima + Indawo Engcolisayo | Intsimbi Yesakhiwo ye-20CrMnTi Alloy | I-Galvanized + I-Sealed Coating | Ilungelelanisa amandla kunye nokumelana nokugqwala, ifanelekile kubavuni bombona

4. Ukudibanisa ulwakhiwo: Unxibelelwano olungenamthungo kunye neeHarvester Sprockets
Iiparameter zesakhiwo se-roller chain kufuneka zihambelane ngokupheleleyo nee-sprockets ezikhoyo ze-harvester; kungenjalo, kuya kukhokelela kwi-meshing embi, ingxolo engaqhelekanga, okanye ukwaphuka.

IiParameters zokuHlanganisa uBume: I-Pitch (ubukhulu obubalulekileyo be-chain, ekufuneka ihambelane ngokupheleleyo ne-sprocket pitch, enempazamo eyi-≤0.05mm), i-Roller Diameter (kufuneka ihambelane nobukhulu be-sprocket tooth groove), i-Inner Pitch Width (ukuthintela i-chain ukuba "ingasebenzi embindini" kwi-sprocket). Iimfuno ezikhethekileyo zoLwakhiwo: Ukuba i-harvester yomthengi yinkqubo yokuthutha ekhawulezayo, i-roller chain ene-guide plates ingacetyiswa ukuthintela ukuphambuka kwe-lateral chain ngexesha lokusebenza. Ukuba indawo yokusebenza inokungcola okuninzi, i-roller chain evaliweyo (enee-sealing rings ezakhelwe ngaphakathi) ingakhethwa ukunciphisa ukungena kokungcola kwi-roller.

III. Indlela Yokukhetha Umthengisi: Amanyathelo ama-3: Ukusuka kuNxibelelwano ukuya kwiSiqinisekiso

Emva kokuqonda imigangatho, kuyimfuneko ukunxibelelana nomthengi ngenkqubo eqhelekileyo ukuqinisekisa ukuchaneka kolwazi lokukhetha kunye nokuphepha iingxabano emva kokuthengisa kamva.

Inyathelo 1: Fumana iinkcukacha zezixhobo zomthengi Cela uphawu lomvuni, imodeli (umz., uJohn Deere S780, Kubota PRO988) kunye nezixhobo ezithile zokusetyenziswa (i-header drive, i-conveyor chain, inkqubo yokubhula) kumthengi. Qinisekisa iinkcukacha zetshaneli yokuqala yecandelo ngencwadi yesikhokelo yesixhobo okanye ulwazi lomenzi njengesiseko sokukhetha.

Inyathelo lesi-2: Yongeza ngemibuzo eneenkcukacha ngemeko yokusebenza Sebenzisa imibuzo elula ukucacisa iiparameter eziphambili, ezinje: “Zeziphi izityalo ezivunwa kakhulu ngumvuni wakho?” “Lithini ixesha lokusebenza eliqhelekileyo lemihla ngemihla ngomatshini ngamnye?” “Ingaba yindawo yokusebenza yerayisi okanye ngumhlaba owomileyo?” Guqula iimfuno ezingacacanga zibe ziiparameter ezithile zobugcisa. Inyathelo lesi-3: Nika izisombululo zokukhetha kunye nezilumkiso zomngcipheko. Nika abathengi izisombululo ezifanelekileyo ezi-1-2 (umz., isisombululo esiphambili + enye indlela engabizi kakhulu), ebonisa ngokucacileyo iimeko ezifanelekileyo kunye namanyathelo okhuseleko kwisisombululo ngasinye. Umzekelo: “Itsheyini yesisombululo soku-1 ifanelekile kwimisebenzi yombona enzima, kodwa ifuna ukuthambisa rhoqo emva kweeyure ezi-6; Isisombululo sesi-2 sitshiphu nge-15%, kodwa sicetyiswa kuphela kwimisebenzi yengqolowa elula.”

IV. Iingcamango Ezingachanekanga Zokukhetha Okuqhelekileyo: Iingxaki Ezi-3 Abathengisi Abafanele Baziphephe

Ingcamango Engachanekanga 1: Ukugxila kwiPitch kuphela, Ukungayinaki eminye iParameters. Abanye abathengisi bakholelwa ukuba “ukuba ipitch ilungile, ingasetyenziswa,” kodwa bayayityeshela i-roller diameter kunye nobubanzi be-link yangaphakathi, nto leyo ekhokelela ekuxinaniseni i-chain ngexesha lokudibana kwe-sprocket, kwaye kwiimeko ezinzima, umonakalo kwi-sprocket. Abathengi kufuneka bakhunjuzwe: i-chain “ihambelana ngokupheleleyo,” kwaye zonke iiparameter zesakhiwo kufuneka zihambelane ne-chain yokuqala.

Ingcamango Engachanekanga 2: Ukucebisa Ngokungaqondiyo "IiTyathanga Ezibizayo." Iityathanga ezibiza kakhulu zisenokungahlangabezani neemfuno zabathengi. Umzekelo, ukucebisa iityathanga zentsimbi engagqwaliyo zamasimi engqolowa eyomileyo kuya kunyusa iindleko zabathengi, kwaye intsimbi engagqwaliyo ayinamandla njengentsimbi ye-alloy, nto leyo enokunciphisa ubomi bayo. Isisombululo "esingabizi kakhulu" kufuneka sicetyiswe ngokusekelwe kwiimeko zokusebenza, kungekhona isisombululo "esibiza kakhulu".

Ingcamango ephosakeleyo 3: Ukungayinaki imiqathango yokufakela nokugcina. Ukuba indawo yomthengi ayinabo abasebenzi abaziingcali bokugcina, kufuneka kucetyiswe ityathanga elineempawu "ezingenalo ulondolozo" (ezifana netyathanga elivaliweyo elineringi yokutywina) kwaye iimfuno zokuthambisa kufuneka zenziwe lula. Ukuba izixhobo zomthengi zinendawo encinci yokufaka, kufuneka kuqinisekiswe ukuba i-radius encinci yokugoba yetyathanga ukuze kuthintelwe ukungaphumeleli kokufaka.
