I-power take-off (PTO) iyisisetshenziswa esiwumshini esidlulisa amandla enjini noma emoto esuka emishinini yezimboni iye kuzinhlelo zokusebenza ezihlukahlukene. Ama-PTO avame ukusetshenziswa emalolini ezentengiselwano ukuthutha impahla, izinto zokusetshenziswa, kanye nemikhiqizo eqediwe. Badlala indima ebalulekile ekuqinisekiseni ukuthi lamaloli ahamba kahle ngesilinganiso esikhulu.
Okuqukethwe
Amandla kanye Nempumelelo Yezinjini Zezohwebo Zamaloli
Izinjini ezintsha zamaloli ezentengiselwano zifakwe amandla amakhulu, zinikeza ukusebenza kahle kwamandla okufika ku-46% nokusebenza okuthembekile. Ngokuthuthuka kokuzenzakalelayo nokufunda komshini, lezi zinjini zingathuthukisa ukusebenza kahle kukaphethiloli kunoma yisiphi isimo somgwaqo noma indawo. Ukutshala imali ezinjinini zamaloli zakamuva kuveza izinzuzo eziphezulu, njengoba zenzelwe ukukhulisa ukusebenza kahle kuyilapho kwehlisa izindleko ezihlobene nokusetshenziswa kukaphethiloli.
Indlela ama-PTO asebenza ngayo
Ama-PTO axhunywe ku-crankshaft yenjini yeloli futhi adlulise amandla enjini ngokusebenzisa i-drive shaft kuya ezintweni ezinamathiselwe. Ama-PTO asebenzisa amandla enjini noma kagandaganda ukuze aguqule amandla azungezayo abe amandla adonsa kanzima, angasetshenziswa ukushayela izingxenye ezisizayo njengamaphampu, ama-compressor, nezifafazi. Lezi zinhlelo zixhuma ezinjinini zezimoto nge-crankshaft futhi zenziwa zisebenze ngamalever noma iswishi.
Izinzuzo Zokuxhunywa kwe-PTO Nenjini Yamaloli
Ukuxhumana okuthembekile phakathi kwe-PTO nenjini yeloli kunikeza izinzuzo ezimbalwa, okuhlanganisa ukusebenza kalula, amazinga omsindo ancishisiwe, ukusebenza okuthembekile kokuvimbela ukudlidliza, ukudluliswa kwamandla okuphumelelayo, kanye nokusebenza okonga uphethiloli nokonga.
Izinhlobo ze-PTO Systems
Amasistimu we-PTO amaningana ayatholakala, ngalinye linikeza izici ezihlukile nezinzuzo. Ezinye zalezi zinhlobo zihlanganisa:
- Hlukanisa shaft: Lolu hlobo lwesistimu ye-PTO lusebenzisa u-gearbox wesibili oxhunywe nge-splined shaft, okuvumela umshayeli ukuthi asebenzise kahle amandla kunoma iyiphi i-engeli futhi abambe noma akhiphe i-PTO. Ilungele izinhlelo zokusebenza eziningi, ikakhulukazi uma ukusebenzelana okusheshayo nokuvamile noma ukuhoxiswa kwe-PTO kudingekile.
- I-Sandwich split shaft: Lolu hlobo lwe-shaft lubekwe phakathi kwe-transmission nenjini futhi lungasuswa kalula kuzo zombili iziphetho ngokukhipha amabhawodi ambalwa nje. Ngekhono layo elithembekile nelilinganayo lokudlulisa amandla, iSandwich Split Shaft isiphenduke uhlelo olujwayelekile lwe-PTO.
- Ukukhweza okuqondile: Lolu hlelo luvumela ukudluliselwa ukuthi aphambukise amandla enjini ukusuka kumotho engaphansi ukuya ohlelweni lwangaphandle. Ivumela imiklamo ehlangene, ukuhlanganisa kalula kanye nesevisi, izingxenye ezincishisiwe nezindleko zabasebenzi, ukufinyelela okulula kokulungiswa kwenjini, kanye nokunqanyulwa kwe-clutch okuphumelelayo.
Ukusetshenziswa kwamayunithi e-PTO Emalolini Ezentengiso
Amayunithi e-PTO avame ukusetshenziswa ekuthungeni amaloli ukuze anike amandla uhlelo lokuvuthela, ukuphakamisa umbhede wokulahla amaloli, ukusebenzisa iwintshi iloli lokudonsa, ephethe umshini wokulahla udoti wamaloli, kanye nomshini wokukha amanzi. Lapho ukhetha i-PTO efanele ngezidingo ezithile, kubalulekile ukucabangela uhlobo lohlelo, inani lezesekeli ezidingekayo, inani lomthwalo okhiqizwayo, noma yiziphi izidingo ezikhethekile, kanye nezidingo zetorque zokukhipha zohlelo.
Isiphetho
Ama-PTO abalulekile ekuqinisekiseni ukuthi amaloli ezentengiselwano ahamba kahle nangempumelelo. Ukuqonda izinhlobo zezinhlelo ze-PTO ezitholakalayo kanye nezicelo zazo kungasiza ekukhetheni i-PTO efanele ngezidingo ezithile.
