Ukuqonda Umahluko phakathi koxinzelelo kunye noLawulo lokuHamba
2024-09-29Iinkqubo ze-pneumatic zisetyenziswa ngokubanzi kunye nezisombululo zeendleko zokuhambisa amandla kunye namandla kwizixhobo, izixhobo kunye neenkqubo zoshishino. Zonke iinkqubo ze-pneumatic zithembele kuzo zombini uxinzelelo kunye nokuhamba ukuze zisebenze ngokufanelekileyo. Ngelixa ulawulo loxinzelelo kunye nolawulo lokuhamba ziingcamango ezahlukileyo, zihambelana ngokusondeleyo; ukulungelelanisa enye kuya kuchaphazela enye. Eli nqaku lijolise ekucaciseni umahluko phakathi koxinzelelo kunye nokulawula ukuhamba, ukwenza lula ubudlelwane babo, kwaye baxoxe ngezixhobo ezahlukeneyo zokulawula uxinzelelo kunye neevalve zokulawula ukuhamba eziqhelekileyo ezifumaneka kwizicelo ze-pneumatic.
Ukuchaza uxinzelelo kunye nokuhamba kwiiNkqubo ze-Pneumatic
Uxinzelelouchazwa njengamandla asetyenziswa kwindawo ethile. Ukulawula uxinzelelo kubandakanya ukulawula indlela ehamba ngayo kwaye iqulethwe ngaphakathi kwenkqubo ye-pneumatic ukuqinisekisa ukunikezelwa kwamandla okuthembekileyo kunye okwaneleyo.Phula, kwelinye icala, ibhekisa kwisantya kunye nevolumu apho umoya ocinezelekileyo uhambayo. Ukulawula ukuhamba kuhambelana nokulawula ukuba ukhawuleza kangakanani kwaye ungakanani umthamo womoya ohambayo kwisixokelelwano.
Inkqubo esebenzayo ye-pneumatic idinga zombini uxinzelelo kunye nokuhamba. Ngaphandle koxinzelelo, umoya awukwazi ukusebenzisa amandla aneleyo kwizicelo zombane. Ngokwahlukileyo, ngaphandle kokuhamba, umoya ocinezelekileyo uhlala ugcinwe kwaye awukwazi ukufikelela kwindawo ekujoliswe kuyo.
Ulawulo loxinzelelo vs. Ulawulo lokuqukuqela
Ngamagama alula,uxinzeleloinxulumene namandla kunye nokomelela komoya. Kulawulo loxinzelelo, amandla avelisiweyo alingana noxinzelelo olwandisiweyo ngendawo equlethwe kuyo. Ngoko ke, igalelo eliphezulu loxinzelelo kwindawo encinci inokudala amandla afanayo njengegalelo eliphantsi loxinzelelo kwindawo enkulu. Ulawulo loxinzelelo lulawula zombini igalelo kunye nemveliso yempembelelo yokugcina uxinzelelo oluzinzileyo, olulungeleleneyo olufanelekileyo kwisicelo, olufunyenwe ngokuqhelekileyo ngesixhobo sokulawula uxinzelelo.
Phulainxulumene nomthamo kunye nesantya somoya. Ulawulo lokuqukuqela lubandakanya nokuba uvule okanye uthintele indawo apho umoya unokuhamba khona, ngaloo ndlela ulawula ukuba ungakanani kwaye ukhawuleza kangakanani na umoya ocinezelekileyo ohambayo kwisixokelelwano. Ukuvula okuncinci kubangela ukuhamba komoya okuncinci kuxinzelelo olunikiweyo ngokuhamba kwexesha. Ulawulo lokuqukuqela ludla ngokulawulwa ngevalve yolawulo lokuqukuqela elungelelanisa ukuvumela okanye ukuthintela ukuhamba komoya ngokuchanekileyo.
Ngelixa uxinzelelo kunye nolawulo lokuhamba luhluke, zibaluleke ngokulinganayo iiparameters kwi-pneumatic system kwaye zixhomekeke omnye komnye ngokusebenza okufanelekileyo. Ukulungelelanisa enye inguqu ngokuqinisekileyo kuya kuchaphazela enye, kuchaphazela ukusebenza kwenkqubo iyonke.
Kwinkqubo efanelekileyo ye-pneumatic, ukulawula enye inguqu ukuphembelela enye kunokubonakala ngathi kuyenzeka, kodwa usetyenziso lwehlabathi lokwenyani alufane lubonise iimeko ezifanelekileyo. Umzekelo, ukusebenzisa uxinzelelo lokulawula ukuhamba kunokungachaneki kwaye kukhokelela kwiindleko eziphezulu zamandla ngenxa yokuhamba komoya okugqithisileyo. Isenokubangela ucinezelo olugqithisileyo, izinto ezonakalisayo okanye iimveliso.
Ngakolunye uhlangothi, ukuzama ukulawula uxinzelelo ngokulawula ukuhamba kunokubangela ukuhla koxinzelelo xa ukunyuka komoya kunyuka, okukhokelela kunikezelo loxinzelelo olungazinzanga olunokusilela ukuhlangabezana neemfuno zamandla esicelo ngelixa uchitha amandla ngokugqithiswa komoya.
Ngezi zizathu, kudla ngokucetyiswa ukuba kulawulwe ulawulo lokuqukuqela kunye noxinzelelo loxinzelelo ngokwahlukeneyo kwinkqubo yomoya.
Uxinzelelo kunye neZixhobo zoLawulo lokuHamba
Iivalvu zokulawula ukuhambazibalulekile ekulawuleni okanye ekulungiseni ukuhamba komoya (isantya) ngokusebenzisa iinkqubo zomoya. Iindidi ezahlukeneyo ziyafumaneka ukuze zilungele izicelo ezahlukeneyo, kubandakanya:
• Iivalvu zoLawulo oluLungelelwano: Ezi zilungelelanisa ukuhamba komoya ngokusekelwe kwi-amperage esetyenziswe kwi-solenoid ye-valve, ukuhluka kokuphuma kokuphuma ngokufanelekileyo.
• Iivalvu zebhola: Inebhola engaphakathi encanyathiselwe kwisiphatho, ezi zivalo zivumela okanye zithintele ukuhamba kwamanzi xa zijika.
• Iivalve zebhabhathane: Ezi zisebenzisa ipleyiti yentsimbi edityaniswe kwisibambo okanye ukuvula (ukuvumela) okanye ukuvala (ibhloko) ukuhamba.
• Iivalvu zeenaliti: Ezi zibonelela ngolawulo lokuhamba ngenaliti evulayo okanye evalayo ukuze ivumele okanye ithintele ukuhamba komoya.
Ukulawulauxinzelelo(okanye amandla / amandla), iivalve zokulawula uxinzelelo okanye izilawuli zoxinzelelo zisetyenziswa. Ngokuqhelekileyo, iivalve zokulawula uxinzelelo zivaliwe, ngaphandle kweevalve zokunciphisa uxinzelelo, ezihlala zivulekile. Iindidi eziqhelekileyo ziquka:
• IiValuvu zokuNceda uxinezeleko: Ezi zinciphisa uxinzelelo oluphezulu ngokuphambukisa uxinzelelo olugqithisileyo, ukukhusela izixhobo kunye neemveliso kumonakalo.
• IiValuvu zokuNciphisa uxinzelelo: Ezi zigcina uxinzelelo oluphantsi kwinkqubo ye-pneumatic, ukuvala emva kokufikelela kwingcinezelo eyaneleyo yokukhusela ukugqithisa.
• Iivalvu zolandelelwano: Ngokuqhelekileyo zivaliwe, ezi zilawula ukulandelelana kwentshukumo ye-actuator kwiinkqubo ezine-actuator ezininzi, ezivumela uxinzelelo ukuba ludlule ukusuka kwi-actuator ukuya kwelinye.
• Iivalvu ezichaseneyo: Ngokuqhelekileyo ivalwe, ezi zigcina uxinzelelo olumiselweyo kwicandelo le-pneumatic system, ukuphikisana namandla angaphandle.
Ukufumana ulwazi oluthe kratya malunga nokulawula uxinzelelo kunye nokuhamba kwiinkqubo ze-pneumatic, zikhululeke ukufikelela!
