Indima nohlobo lwendandatho yamafutha
2020-12-02
Umsebenzi wendandatho kawoyela ukusabalalisa ngokulinganayo uwoyela wokugcoba ochaphaza odongeni lwesilinda lapho i-piston ikhuphuka, okuzuzisa ukugcotshwa kwepiston, indandatho yepiston kanye nodonga lwesilinda; lapho i-piston ihamba phansi, ikhuhla amafutha amaningi okugcoba odongeni lwesilinda ukuvimbela ukugcotshwa Ukuphulwa kwegumbi elivuthayo ukuze lishise. Ngokwesakhiwo esihlukile, indandatho yamafutha ihlukaniswe yaba izinhlobo ezimbili: indandatho yamafutha evamile kanye nendandatho yamafutha ehlanganisiwe.
Indandatho yamafutha ajwayelekile
Isakhiwo sendandatho kawoyela evamile ngokuvamile senziwe nge-alloy cast iron. Umsele usikwa phakathi nendawo eyindilinga yangaphandle, futhi izimbobo eziningi zokukhipha uwoyela noma izimbotshana zenziwa ngomshini ngaphansi komsele.
Indandatho yamafutha ehlanganisiwe
Indandatho kawoyela ehlanganisiwe yakhiwe ama-scrapers aphezulu naphansi kanye nentwasahlobo yomugqa ophakathi. Ama-scrapers enziwe ngensimbi e-chrome-plated. Esimeni samahhala, ububanzi obungaphandle be-scraper efakwe entwasahlobo ye-lining bukhulu kancane kunobubanzi be-cylinder. Ibanga phakathi kwama-blades nalo likhudlwana kancane kunobubanzi be-groove ring. Lapho indandatho kawoyela ehlanganisiwe nepiston kufakwa kusilinda, isiphethu se-liner sicindezelwa kuzo zombili izikhombisi-ndlela ze-axial ne-radial. Ngaphansi kwesenzo samandla entwasahlobo we-liner spring, i-wiper ingaqiniswa. Ukucindezela odongeni lwesilinda kuthuthukisa umphumela wokukhuhla uwoyela. Ngesikhathi esifanayo, ama-scrapers amabili aphinde abambene ngokuqinile emseleni oyindandatho. Indandatho kawoyela ehlanganisiwe ayinakho ukuhlehla, ngaleyo ndlela inciphisa umphumela wokupompa uwoyela weringi ye-piston. Lolu hlobo lwendandatho kawoyela lunokucindezela okukhulu kokuxhumana, ukuguquguquka okuhle odongeni lwesilinda, indawo enkulu yokubuyisela uwoyela, isisindo esincane, nomphumela osobala wokukhuhla uwoyela. Ngakho-ke, indandatho kawoyela ehlanganisiwe isetshenziswa kabanzi ezinjinini ezinesivinini esikhulu. Ngokuvamile, amasongo kawoyela owodwa kuya kwamabili afakwa ku-piston. Uma kusetshenziswa izindandatho ezimbili zamafutha, ephansi ivame ukubekwa ekugcineni okuphansi kwesiketi se-piston.
