A isixhobo somoya(ekwabizwa ngokuba yi *pneumatic cylinder* okanye *air actuator*) sisixhobo esibalulekileyo kwi-industrial automation. Siguqula amandla omoya acinezelweyo abe yintshukumo yoomatshini abevula, vala, okanye ulungise iivalvu, okuvumela ulawulo oluchanekileyo lokuhamba kolwelo kwiipayipi. Eyaziwa ngokuthembeka, isantya, kunye nokukwazi ukumelana nokuqhuma, ii-actuators zomoya zisetyenziswa kakhulu kwizityalo zamandla, ekucutshungulweni kweekhemikhali, kwiindawo zokucoca ioyile, nakwezinye izinto.
Zisebenza njani ii-Pneumatic Actuators
Ii-actuators ze-pneumatic zixhomekeke emoyeni ocinezelweyo ukuqhuba ii-piston okanye ii-diaphragms, zivelisa intshukumo ethe tye okanye ejikelezayo. Xa uxinzelelo lomoya lusanda, amandla atyhala ipiston okanye i-diaphragm, edala intshukumo esebenzisa iivalvu ezidibeneyo. Le ndlela ivumela amaxesha okuphendula ngokukhawuleza kunye ne-torque ephezulu, nto leyo eyenza ukuba zilungele iindawo zoshishino ezifuna amandla.
Iintlobo zee-Actuators ze-Pneumatic
Ii-actuators ze-pneumatic zahlulwe ngohlobo lwentshukumo, ulwakhiwo, kunye nendlela yokusebenza. Apha ngezantsi kukho iintlobo eziphambili, kuqukaukubuya kwentwasahlobo, esebenza kabinikunyeIi-actuators ze-pneumatic zeScotch Yoke:
1. Ngohlobo lweNtshukumo
- Ii-Actuators eziLungelelanisiweyo: Velisa intshukumo ethe tye (umz., iintonga zokutyhala-ukutsala kwiivalvu zesango).
- Ii-Actuators ze-Angular/Rotary: Yenza intshukumo yokujikeleza (umz., iivalvu zebhola ezijika ikota okanye ibhabhathane).
2. Ngoyilo lweZakhiwo
- Ii-Actuators ze-DiaphragmSebenzisa uxinzelelo lomoya ukuze ugobe i-diaphragm, efanelekileyo kwimisebenzi enamandla aphantsi nachanekileyo.
- Ii-Actuators zePiston: Nika amandla aphezulu kwiivalvu ezinkulu okanye kwiinkqubo zoxinzelelo oluphezulu.
- Ii-Actuators zeRack-and-Pinion: Guqula intshukumo ethe tye ibe kukujikeleza ukuze kulawulwe ivalvu ngokuchanekileyo.
- Ii-Actuators ze-Scotch Yoke PneumaticSebenzisa indlela yejoko etyibilikayo kwi-torque ephezulu kwimisebenzi enzima (umz., iivalvu ezinkulu zebhola).
3. NgeModi yokuSebenza
I-Actuator ye-Pneumatic yokubuya kwentwasahlobo (esebenza kanye):
– Isebenzisa umoya ocinezelweyo ukuhambisa i-piston ngelixaintwasahlobo ibonelela ngokuseta kwakhona ngokuzenzekelayoxa umbane womoya unqanyulwe.
– Iintlobo ezimbini: *Ivuleka ngesiqhelo* (ivala ngomoya, ivuleka ngaphandle) kunye *Ivaliwe ngesiqhelo* (ivula ngomoya, ivale ngaphandle).
– Ilungele ukusetyenziswa okukhuselekileyo okufuna ukubuyiselwa kwesikhundla sevalvu ngexesha lokuphelelwa ngumbane.
I-Actuator ye-Pneumatic esebenza kabini:
– Ifuna umoya ophumayo kumacala omabini episton ukuze intshukumo ibe macala omabini.
– Akukho ndlela yokuvula intwasahlobo; ilungele imisebenzi eqhubekayo efuna ukutshintshwa rhoqo kweevalvu.
– Inika amandla aphezulu xa ithelekiswa neemodeli zokubuyisela izinto entwasahlobo.
Izicelo eziphambili ze-Pneumatic Actuators
Ii-actuators zomoya zibalasele kumashishini afuna ukhuseleko, isantya, kunye nokuqina. Nazi iimeko zazo eziphambili zokusetyenziswa:
1. Iimfuno zeHigh-Trust: Ukunika amandla iivalvu ezinkulu kwiipayipi okanye kwiinkqubo zoxinzelelo.
2. Iindawo ezinobungozi: Ukusebenza okungenakuqhuma kwiindawo zokucoca ioyile, kwizityalo zeekhemikhali, okanye kwimigodi.
3. Ulawulo lweValve olukhawulezayo: Iinkqubo zokuphendula ngokukhawuleza xa kucinywa umbane ngexesha likaxakeka okanye kuhlengahlengiswa ukuhamba kwamanzi.
4. Iimeko Ezinzima: Ukusebenza okuthembekileyo kumaqondo obushushu agqithisileyo, ukufuma, okanye iindawo ezirhabaxa.
5. Iinkqubo zokuZenzekelayo: Ukudibanisa nee-PLC ukuze kulawulwe inkqubo engenamthungo.
6. Ukutshintsha ngesandla/okuzenzakalelayo: Ivili lesandla elakhelwe ngaphakathi ukuze liguqulwe ngesandla xa inkqubo ingasebenzi.
Kutheni Ukhetha ii-Actuators ze-Pneumatic
- Impendulo ekhawulezileyo: Ukusabela kwangoko kwiimpawu zolawulo.
- Ukuthembeka okuphezulu: Ulondolozo oluncinci kunye nolwakhiwo oluqinileyo.
- Ukhuseleko lokuqhuma: Akukho ziqhushumbisi zombane, zilungele iindawo ezinokutsha.
- Isebenza kakuhle emalini: Iindleko eziphantsi zokuqala nezokusebenza xa kuthelekiswa nezinye iindlela ze-hydraulic/electric.
Isiphelo
Ukuqondayintoni i-actuator ye-pneumatickunye nokukhetha uhlobo olufanelekileyo—nokubai-actuator ye-pneumatic yokubuya kwentwasahlobo, i-actuator esebenza kabiniokanyeI-actuator ye-pneumatic yeScotch Yoke—iqinisekisa ukusebenza kakuhle kwiinkqubo zoshishino. Ngokufanisa uyilo lwe-actuator (olunemigca, olujikelezayo, oluyi-diaphragm, okanye oluyi-piston) neemfuno zakho zokusebenza, uphucula ukusebenza kakuhle, ukhuseleko, kunye nobude bexesha kwizicelo zolawulo lolwelo.
Kwimizi-mveliso ebeka phambili ukuchaneka, ukuqina, kunye nokhuseleko, ii-actuators zomoya zihlala zisisombululo esifanelekileyo sokwenza ii-valve automation.
