Ngokwezidingo kanye nemibandela yokusebenza, khetha kahle uhlobo lwesilinda. Uma isilinda sidingeka ukuthi sifinyelele ekugcineni kwe-stroke ngaphandle komthelela nomsindo womphumela, kufanele kukhethwe isilinda sebhafa; uma kudingekile ukuba kube nesisindo esincane, kufanele kukhethwe isilinda esikhanyayo; uma kudingekile ukuba kube nesikhala sokufaka esincane kanye ne-stroke emfushane, i-cylinder encane ingakhethwa; uma kukhona umthwalo we-lateral, i-cylinder enenduku yomhlahlandlela ingakhethwa; Uma ukunemba kwebhuleki kuphakeme, kufanele kukhethwe isilinda sokukhiya; uma induku ye-piston ingavunyelwe ukujikeleza, isilinda esinomsebenzi ongaphenduki wenduku singakhethwa; endaweni yokushisa ephezulu, isilinda esimelana nokushisa kufanele sikhethwe; endaweni egqwalayo, kufanele kukhethwe isilinda esimelana nokugqwala. Ezindaweni ezinokhahlo njengothuli, kuyadingeka ukufaka isembozo sothuli ekugcineni kwenduku ye-piston. Uma kungekho ukungcola okudingekayo, kuyadingeka ukukhetha amasilinda agcotshiwe angenawo uwoyela noma angenawo uwoyela, njll.

2. Ifomu lokufaka

Kuncike ezintweni ezifana nendawo yokufaka nenjongo yokusebenzisa. Ngokuvamile, kusetshenziswa isilinda esingaguquki. Uma kudingekile ukujikeleza ngokuqhubekayo ngomshini wokusebenza (njengama-lathes, ama-grinders, njll.), i-cylinder ejikelezayo kufanele ikhethwe. Uma i-piston rod idingeka ukwenza i-arc swing ngaphezu kokunyakaza komugqa, isilinda sephini ye-pivot siyakhethwa. Uma kunezidingo ezikhethekile, i-cylinder ekhethekile ehambisanayo kufanele ikhethwe. I-akhawunti yomphakathi "Mechanical Engineering Literature", isiteshi sikaphethiloli sonjiniyela!

3. Ubukhulu bamandla

Okusho ukuthi, ukukhetha kwe-diameter ye-bore. Nquma i-thrust kanye nokudonsa amandla okukhiphayo ngesilinda ngokuya ngamandla omthwalo. Ngokuvamile, amandla e-cylinder adingwa yisimo sebhalansi yethiyori yomthwalo wangaphandle asetshenziswa, futhi amazinga omthwalo ahlukene akhethwa ngokuvumelana nesivinini esihlukene, ukuze amandla okukhipha isilinda abe nomkhawulo omncane. Uma ububanzi be-cylinder buncane kakhulu, amandla okukhiphayo ayanele, kodwa uma ububanzi be-cylinder bukhulu kakhulu, imishini izoba nkulu, izindleko zizokwanda, futhi ukusetshenziswa komoya kuzokwandiswa, okuzochitha amandla. Ekwakhiweni kwesakhiwo, indlela yokwandisa kufanele isetshenziswe ngangokunokwenzeka ukuze kuncishiswe usayizi ophelele wesilinda.

4. Piston stroke

Kuhlobene nesikhathi sokusetshenziswa kanye nokushaywa komshini, kodwa ngokuvamile ukushaywa okugcwele akukhethiwe ukuze kuvinjwe ipiston ukuthi ingashayisani nekhanda lesilinda. Uma isetshenziselwa umshini wokuhlanganisa, njll., umkhawulo ka-10-20mm kufanele wengezwe ngokuya ngokushaya okudingekayo ekubaleni.

5. Ijubane lokunyakaza kwepiston

Incike kakhulu esilinganisweni sokugeleza komoya esicindezelwe okokufaka, usayizi wezimbobo zokungenisa kanye ne-exhaust yesilinda kanye nobubanzi bangaphakathi bomzila. Kudingeka ukuthatha inani elikhulu lokunyakaza kwesivinini esikhulu. Isivinini sokunyakaza kwesilinda ngokuvamile singu-50-800mm/s. Kuma-cylinders ahamba ngesivinini esiphezulu, ipayipi yokungena enobubanzi obukhulu bangaphakathi kufanele ikhethwe; ukuze kutholakale izinguquko zomthwalo, ukuze kutholwe isivinini sokunyakaza esihamba kancane futhi esizinzile, idivayisi edonsayo noma isilinda sokudambisa uketshezi lwegesi, okulula ukufeza ukulawula isivinini. Uma ukhetha i-valve ye-throttle ukulawula isivinini se-cylinder, ukunakwa kufanele kukhokhwe: lapho isilinda esifakwe ngokuvundlile siphusha umthwalo, kunconywa ukusebenzisa i-exhaust throttling ukulungisa isivinini; lapho isilinda esifakwe mpo siphakamisa umthwalo, kunconywa ukusebenzisa i-air intake throttling ukulungisa isivinini; ukunyakaza ekupheleni kwe-stroke kuyadingeka ukuze kube bushelelezi Uma ugwema umthelela, isilinda esinomshini we-buffer kufanele sikhethwe.
