Indlela yokukhetha i-cylinder ye-pneumatic?

1) Ukukhethwa kwe-Pneumatic cylinder:

Kucetyiswa ukuba ukhethe aisilinda somoya esisemgangathweni ukuba akunjalo, cinga ukuyila ngokwakho.

Ulwazi malunga ne-aluminiyam yesilinda somoya (Yenziwe yi-Aluminiyam Cylinder Tube) ukhetho:

(1) Uhlobo lwesilinda ye-pneumatic:

Ngokweemfuno zokusebenza kunye neemeko, uhlobo oluchanekileyo lwesilinda lukhethiweyo.Iisilinda ezikwaziyo ukumelana nobushushu kufuneka zisetyenziswe kwiindawo zobushushu obuphezulu.Kwindawo enomhlwa, i-cylinder enganyangekiyo iyafuneka.Kwiindawo ezinzima ezifana nothuli, isigqubuthelo sothuli kufuneka sifakwe kwisiphelo sokwandiswa kwentonga yepiston.Xa kungenangcoliseko kufuneka kukhethwe iisilinda zokuthambisa ezingenawo ioyile okanye ezingenaoyile.

(2) Indlela yokufakela:

Ukumiselwa ngokwezinto ezifana nendawo yokufakela, injongo yokusetyenziswa, njl.

Iifom zofakelo zezi: uhlobo olusisiseko, uhlobo lonyawo, uhlobo lweflange yentonga, uhlobo lweflange olungenantonga, uhlobo lwamacici elinye, uhlobo lwamacici aphindwe kabini, uhlobo lwe-trunnion yentonga, uhlobo lwe-trunnion ye-rodless, uhlobo lwe-trunnion ephakathi.

Ngokuqhelekileyo, i-cylinder esisigxina isetyenziswa.Iisilinda zomoya ezijikelezayo kufuneka zisetyenziswe xa ujikelezo oluqhubekayo kunye nomatshini wokusebenza (njengama-lathes, grinders, njl.) kufuneka.Xa intonga yepiston ifuneka ukuba ihambe kwi-arc ngaphezu kokuhamba komgca, iisilinda ze-pneumatic ze-shaft zisetyenziswa.Xa kukho iimfuno ezikhethekileyo, i-cylinder yomoya ekhethekileyo ehambelanayo kufuneka ikhethwe.

(3) Ukubetha kweintonga yepiston:

inxulumene nesiganeko sokusetyenziswa kunye nokubetha komatshini, kodwa ngokubanzi i-stroke epheleleyo ayisetyenziselwa ukuthintela ipiston kunye nentloko yesilinda ukuba ingangqubani.Ukuba isetyenziselwa i-clamping mechanism, njl., i-margin ye-10 ~ 20mm kufuneka yongezwe ngokuhambelana ne-stroke ebalwayo.I-stroke esemgangathweni kufuneka ikhethwe ngokusemandleni ukuqinisekisa ukuhanjiswa kwesantya kunye nokunciphisa iindleko.

(4) Ubukhulu bamandla:

I-thrust kunye nokutsala amandla okukhutshwa yi-cylinder kunqunywe ngokobukhulu bomthwalo womthwalo.Ngokuqhelekileyo, i-force of the cylinder efunwa yimeko yokulinganisa i-theoretical yomthwalo wangaphandle iphindaphindwa nge-coefficient 1.5 ~ 2.0, ukwenzela ukuba amandla okukhutshwa kwe-cylinder abe nomda omncinci.Ukuba i-diameter ye-cylinder incinci kakhulu, amandla aphumayo awanelanga, kodwa ububanzi be-cylinder bukhulu kakhulu, okwenza izixhobo zibe zininzi, ukwandisa iindleko, ukwandisa ukusetyenziswa komoya, kunye nokuchitha amandla.Kuyilo lwesakhiwo, indlela yokwandisa amandla kufuneka isetyenziswe kangangoko ukunciphisa ubungakanani bangaphandle besilinda.

(5) Ifomu yesithinteli:

Ngokweemfuno zesicelo, khetha ifom ye-cushioning ye-cylinder.Iifom zesithinteli se-cylinder zahlulwe zibe: akukho buffer, irabha buffer, air buffer, hydraulic buffer.

(6) Isantya sentshukumo yepiston:

ubukhulu becala kuxhomekeke kwigalelo elicinezelweyo izinga lokuhamba komoya le-cylinder, ubungakanani bokungena kwe-cylinder kunye ne-exhaust port kunye nobubanzi bangaphakathi bombhobho.Kuyimfuneko ukuba ukunyakaza kwesantya esiphezulu kufuneka kuthathe ixabiso elikhulu.Isantya sokuhamba kwe-cylinder ngokuqhelekileyo yi-50 ~ 1000mm / s.Kwiisilinda zesantya esiphezulu, kufuneka ukhethe umbhobho wokungenisa umjelo omkhulu wangaphakathi;kutshintsho lomthwalo, ukuze ufumane isantya esicothayo nesizinzileyo sokubaleka, ungakhetha isixhobo sompompoza okanye i-cylinder yokudambisa i-gas-liquid, ekulula ukufikelela kulawulo lwesantya..Xa ukhetha i-valve ye-throttle ukulawula isantya se-cylinder, nceda uhlawule ingqalelo: xa i-cylinder efakwe ngokuthe tye ityhala umthwalo, kucetyiswa ukuba usebenzise ukulawulwa kwesantya se-throttle exhaust;xa i-cylinder efakwe ngokuthe nkqo iphakamisa umthwalo, kuyacetyiswa ukuba usebenzise ukulawulwa kwesantya se-throttle intake;intshukumo ye-stroke iyadingeka ukuba izinzile Xa uphepha impembelelo, isilinda esinesixhobo se-buffer kufuneka sisetyenziswe.

(7) Ukutshintsha kwemagneti:

Ukutshintsha kwamagnetic okufakwe kwi-cylinder kusetyenziselwa ukukhangela indawo.Kufuneka kuqatshelwe ukuba i-ring magnetic eyakhelwe-ngaphakathi ye-cylinder iyimfuneko yokuqala yokusebenzisa i-switch magnetic.Iifom zofakelo lokutshintsha kwemagnethi zezi: ufakelo lwentsimbi yentsimbi, ufakelo lomkhondo, ufakelo lwentonga yokutsala, kunye nokufakelwa koqhagamshelo lokwenyani.
