Ngokweemfuno zokusebenza kunye neemeko, khetha ngokuchanekileyo uhlobo lwesilinda. Ukuba i-cylinder iyadingeka ukufikelela ekupheleni kwe-stroke ngaphandle kwempembelelo kunye nesandi sempembelelo, i-cylinder ye-buffer kufuneka ikhethwe; ukuba kufuneka kube lula, kufuneka kukhethwe isilinda esikhanyayo; ukuba kufuneka ube nendawo yokufakela encinci kunye ne-stroke emfutshane, i-cylinder encinci inokukhethwa; ukuba kukho umthwalo osecaleni, i-cylinder enentonga yesikhokelo inokukhethwa; Ukuba ukuchaneka kwe-braking kuphezulu, i-cylinder yokuvala kufuneka ikhethwe; ukuba intonga yepiston ayivumelekanga ukuba ijikeleze, i-cylinder enomsebenzi ongaguqukiyo wentonga inokukhethwa; kwindawo yokushisa okuphezulu, i-cylinder-resistant-resistant cylinder kufuneka ikhethwe; kwindawo enomhlwa, i-cylinder-resistant-resistant kufuneka ikhethwe. Kwiindawo ezinzima ezifana nothuli, kuyimfuneko ukufaka isigqubuthelo sothuli kwisiphelo esiphumayo sentonga yepiston. Xa kungadingeki ungcoliseko, kuyimfuneko ukuba ukhethe iisilinda ezigcotyiweyo ezingenawo ioli okanye ioyile, njl.

2. Ifom yokufakela

Kuxhomekeke kwizinto ezifana nendawo yokufakela kunye nenjongo yokusetyenziswa. Ngokuqhelekileyo, i-cylinder esisigxina isetyenziswa. Xa kuyimfuneko ukujikeleza ngokuqhubekayo kunye nomatshini wokusebenza (njengama-lathes, ama-grinders, njl.), kufuneka kukhethwe i-cylinder ejikelezayo. Xa intonga yepiston ifuneka ukwenza i-arc swing ukongeza kwi-linear motion, i-pivot pin cylinder ikhethiwe. Xa kukho iimfuno ezikhethekileyo, i-cylinder ekhethekileyo ehambelanayo kufuneka ikhethwe.

3. Ubungakanani bamandla

Oko kukuthi, ukhetho lwe-diameter ye-bore. Qinisekisa ukutyhala kunye nokutsala amandla aphumayo ngesilinda ngokuhambelana nomthwalo womthwalo. Ngokuqhelekileyo, amandla e-cylinder afunwa yimeko yokulinganisa i-theoretical yomthwalo wangaphandle isetyenzisiweyo, kwaye amaxabiso ahlukeneyo omthwalo akhethwe ngokwezantya ezahlukeneyo, ukwenzela ukuba amandla okukhutshwa kwe-cylinder abe nomda omncinci. Ukuba ububanzi be-cylinder buncinci kakhulu, amandla okukhutshwa akwanele, kodwa ukuba ububanzi be-cylinder bukhulu kakhulu, izixhobo ziya kuba zikhulu, iindleko ziya kwanda, kwaye ukusetyenziswa komoya kuya kwandiswa, okuya kuchitha amandla. Kuyilo loyilo, indlela yokwandisa kufuneka isetyenziswe kangangoko ukunciphisa ubungakanani be-cylinder.

4. Piston stroke

Inxulumene nesihlandlo sokusetyenziswa kunye nokubetha kwendlela, kodwa ngokuqhelekileyo i-stroke epheleleyo ayikhethwanga ukukhusela ipiston ekungqubaneni nentloko ye-cylinder. Ukuba isetyenziselwa i-clamping mechanism, njl., umda we-10-20mm kufuneka yongezwe ngokuhambelana ne-stroke efunekayo ekubaleni.

5. Isantya sokuhamba sepiston

Ikakhulu ixhomekeke kwigalelo elicinezelweyo lokuhamba komoya we-cylinder, ubungakanani bokungena kunye nokukhupha izibuko ze-cylinder kunye nobubanzi obungaphakathi bombhobho. Kuyafuneka ukuba kuthathe ixabiso elikhulu lokuhamba ngesantya esiphezulu. Isantya sentshukumo yesilinda siqhelekile ukuba yi-50-800mm/s. Kwiisilinda ezihamba ngesantya esiphezulu, umbhobho wokungenisa kunye nobukhulu bangaphakathi kufuneka ukhethwe; ukutshintshwa komthwalo, ukwenzela ukufumana isantya esicothayo nesizinzileyo sokuhamba, isixhobo sokutshiza okanye i-cylinder ye-gas-liquid damping cylinder ingasetyenziswa, ekulula ukufikelela kulawulo lwesantya. Xa ukhetha i-valve ye-throttle ukulawula isantya se-cylinder, kufuneka kuhlawulwe ingqalelo: xa i-cylinder efakwe ngokuthe tye iqhubela umthwalo, kucetyiswa ukuba usebenzise i-throttling yokukhupha ukulungelelanisa isantya; xa i-cylinder efakwe ngokuthe nkqo iphakamisa umthwalo, kuyacetyiswa ukuba usebenzise i-air intake throttling ukulungisa isantya; ukunyakaza ekupheleni kwe-stroke kuyadingeka ukuba kube lula Xa uphepha impembelelo, i-cylinder enesixhobo se-buffer kufuneka ikhethwe.
