Ukukhetha iSilinda yePneumatic

1. Ubungakanani bamandla
Oko kukuthi, ukhetho lwe-cylinder tube ububanzi.Ngokobungakanani bamandla omthwalo, ukutyhala kunye nokutsala amandla okukhutshwa yi-cylinder ye-pneumatic kumiselwa.Ngokuqhelekileyo, i-cylinder force efunwa yimeko yokulinganisa i-theory yomthwalo wangaphandle ikhethiwe, kwaye imilinganiselo yomthwalo ohlukeneyo ikhethwa 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 zikhulu, iindleko zonyuswa, ukusetyenziswa komoya kunyuswa, kwaye amandla achithwa.Kuyilo lwe-fixture, indlela yokwandisa amandla kufuneka isetyenziswe kangangoko ukunciphisa ubukhulu be-cylinder.

2, ukhetho lohlobo
Khetha ngokuchanekileyo uhlobo lwesilinda ngokweemfuno zokusebenza kunye neemeko.Ukuba i-cylinder iyadingeka ukufikelela ekupheleni kwe-stroke ngaphandle kwempembelelo yempembelelo kunye nengxolo yempembelelo, i-cylinder ye-buffer kufuneka ikhethwe;ukuba ubunzima obulula bufunekayo, i-cylinder elula kufuneka ikhethwe;ukuba indawo yokufakela encinci kunye ne-stroke emfutshane iyadingeka, i-cylinder encinci inokukhethwa;ukuba kukho umthwalo osecaleni, i-cylinder yentonga yesikhokelo inokukhethwa;Ukuchaneka okuphezulu kwe-braking, i-cylinder yokuvala kufuneka ikhethwe;ukuba intonga yepiston ayivumelekanga ukuba ijikeleze, i-cylinder enentonga engatshintshiyo ingakhethwa;i-cylinder ekwazi ukumelana nokushisa kufuneka ikhethwe kwindawo yokushisa okuphezulu;i-cylinder-resistant-resistant kufuneka ikhethwe kwindawo enomhlwa.Kwiindawo ezinzima ezifana nothuli, kuyimfuneko ukufaka isigqubuthelo sothuli ekupheleni okwandisiweyo kwentonga yepiston.Xa kungadingeki ungcoliseko, kufuneka kukhethwe i-oyile-free okanye i-oil-free lubricated cylinder.

3. Piston stroke
Inxulumene nesihlandlo sokusetyenziswa kunye nokubetha kwesixhobo, kodwa i-stroke epheleleyo ayikhethwanga ngokubanzi ukukhusela ipiston kunye nentloko yesilinda ukuba ingangqubani.Ukuba isetyenziselwa i-clamping mechanism, njl., isibonelelo se-10 ukuya kwi-20 mm kufuneka yongezwe ngokwe-stroke ebalwayo.

4. Ifomu yokufakela
Kuxhomekeke kwindawo yokufakela, injongo yokusetyenziswa kunye nezinye izinto.Ngokuqhelekileyo, i-cylinder emileyo isetyenziswa.Xa kuyimfuneko ukujikeleza ngokuqhubekayo kunye nomatshini wokusebenza (njengama-lathes, ama-grinders, njl.), i-cylinder ejikelezayo kufuneka ikhethwe.Xa intonga yepiston ifuneka ukuba ujike kwi-arc yesetyhula ukongeza kwintshukumo yomgca, i-cylinder yohlobo lwe-pin isetyenziswa.Xa kukho iimfuno ezikhethekileyo, i-cylinder ekhethekileyo ehambelanayo kufuneka ikhethwe.

5. Isantya sepiston
Ikakhulu ixhomekeke kwigalelo lokuhamba komoya ocinezelweyo we-cylinder, ubungakanani bokungena kunye nokukhupha izibuko ze-cylinder kunye nobukhulu bobubanzi bangaphakathi bombhobho.Kuyafuneka ukuba kuthathwe ixabiso elikhulu kwintshukumo yesantya esiphezulu.Isantya sentshukumo yesilinda siqhelekile ukuba yi-50∞800mm/s.Kwiisilinda ezihamba ngesantya esiphezulu, umbhobho wokungenisa kunye nobukhulu bangaphakathi kufuneka ukhethwe;ukwenzela utshintsho kumthwalo, ukwenzela ukufumana isantya esicothayo nesizinzileyo sokunyakaza, isixhobo sokutshiza okanye i-cylinder ye-gas-liquid damping cylinder ingakhethwa, ekulula ukufikelela kulawulo lwesantya.Xa ukhetha i-valve ye-throttle ukulawula isantya se-cylinder, kufuneka kuqatshelwe: xa i-cylinder efakwe ngokuthe tye ityhala umthwalo, kuyacetyiswa ukuba usebenzise i-throttle yokukhupha ukulungelelanisa isantya;xa i-cylinder efakwe ngokuthe nkqo iphakamisa umthwalo, kuyacetyiswa ukuba usebenzise i-throttle yokuthatha ukulungelelanisa isantya;ukuphela kwe-stroke kuyadingeka ukuba uhambe kakuhle Xa uphepha impembelelo, i-cylinder enesixhobo se-buffer kufuneka isetyenziswe.
