Ko te tohu whaanui ka kiia ko te tohu inenga tika te urupare urupare, a ko te tohu whakaputa o te poari whakahaere e kiia ana ko te tohu tautuhi mo te whakataurite. Ina rereke nga mea e rua, ka whakarereketia te tohu whakaputa ki te kaitahuri ki te hanga i te tuunga o te kaitahuri, a ka whakaritea te reta kotahi-ki-tetahi i waenga i nga wa whakatiki i te kakau takirere me te tohu whakaputa o te poari whakahaere.
Na reira, ko te tuunga takirere he punaha whakahaere urupare me te kaitaua hei tohu ine tika me te putanga o te poari whakahaere hei tohu tohu. Ko te taurangi whakahaere o te punaha whakahaere ko te tohu whakaputa o te tuunga takirere ki te kaitahuri. Ka wehea te kii tuunga takirere ki roto i te tohu ki te tuunga takirere pneumatic me te tuunga takirere taputapu hiko. Pneumatic valve positioner tohu whakauru he tohu hau paerewa, hei tauira, 20 ~ 100kPa tohu hau, ko tana tohu whakaputa he tohu hau angamaheni. Ko nga taputapu hiko hiko tohu tohu tuunga tuunga ko te rere hiko paerewa, tohu ngaohiko mahi ranei, penei i te 4 ~ 20mA tohu rere hiko, 1~5V ranei te tohu ngaohiko mahi, ka huri te taputapu hiko hiko o roto ki te kaha o te papa autō, katahi ka puta te hau. tohu ki te pehanga hurihanga takirere whakahaere. E ai ki te ahunga tuunga ka taea te wehea ki te tuunga takirere kotahi me te tuuranga takirua.
Ko te tuunga takitini me te miihini miihini piston, ko te tuunga takirere kotahi anake te tuunga, ko te tuunga takirua e mahi ana i nga taha e rua o te miihini miihini piston cylinder, ka whai waahi ki nga huarahi e rua. E ai ki te putanga tuunga takirere me te uara whiwhi o te tohu whakauru kua tohua ki te tuunga takirere whai hua me te tuunga takirere tauhohenga.
Ka whakaarahia te tohu whakauru o te tuunga takirere whai hua pai, ka whakanuia ano te tohu whakaputa, kia pai ai te uara whiwhi.
Ka whakaarahia te tohu whakauru o te tuunga takirere tauhohenga, ka whakahekehia te tohu whakaputa ka kino te uara whiwhi. E ai ki te tohu whakauru tohu tohu he tohu whaihanga, he tohu raraunga ranei, ka taea te wehewehe ki te tuunga takirere whaanui me te atanga rorohiko hiko taputapu hiko.
Ko te tohu tohu momo tuunga takirere whanui ko te whaihanga o te pehanga paerewa, te rere hiko ranei, te tohu ngaohiko mahi, te atanga rorohiko taputapu hiko tohu momo tuunga tohu ko te tohu tohu atanga rorohiko. E ai ki te positioner takirere he kore ki te PTM e taea te wehea ki whānui taputapu hiko takirere positioner me te maramarama hiko takirere positioner.
Karekau he PTM te turanga taputapu hiko whanui, na reira, kaore he mohio, kaore e taea te whakaoti i te tatauranga mohio. Ka taea te whakatau i nga tatauranga mohio e pa ana, penei i te utu mo te hongere o te hongere o te hongere, te atanga rorohiko hiko taputapu hiko ka taea hoki te tango i te PID me etahi atu waahanga kaupapa, whakaoti i te tatauranga e tika ana. I katia e te riu pneumatic nga take matua me nga otinga i te tuatahi, me tirotirohia e tatou te katinga o te riipene a-whaiaro katia he aha te take ka nui te rerenga o te riipene, kia kitea ai he nui ake te rerenga o te riipene i te uara paerewa, kei tua atu ko te raru o te kounga hua. Tuarua, ko te putanga o te kaitahuri hiko e kore e honoa ki te pehanga mahi a te upoko kiriata takirere. Ahakoa kua mau te takirere ki te paru.
Valve tuatahi o nga mea katoa, kia tātari a te takirere whaiaro-whakahaere pneumatic takirere katia ko te aha te tatau ki te whai i te nui o te leakage, ki te kite mehemea te leakage o te piha he teitei ake i te uara paerewa, tua atu ko te raruraru kounga hua. Tuarua, ko te putanga o te kaitahuri hiko e kore e honoa ki te pehanga mahi a te upoko kiriata takirere. Ahakoa kua mau te takirere ki te paru.
Ko te kaha o te puna valve kare e uru tika. Ahakoa ka mau te kakau.
Ko te matua o te takirere, te pehanga teitei o te keeti takirere he kakahu wahanga kiriata mahunga takirere te rehu rehu kopae.
Nga hapa o te taputapu tuunga noa.
Ko te whakatuwheratanga o te hau, he nui rawa te kaha o te axial o te puna. He poto rawa te kakau.
Whakaritehia te paera i mua me muri i te rereketanga o te pehanga he nui rawa, he aha te raruraru o te whiriwhiringa tauira.
Ahakoa he iti rawa te kaha o te kaitahuri, ka taea te whakarite nui te pehanga mahi whakaputa tika (PF ki te whakawhānui ake i te kaha whakaputa, mo te hau kati kati, te hurihanga maui o te wahanga whakatikatika (mamae), ara, PO~PL neke, engari me ki te aro ki te huringa o te whakaritenga whiu katoa No.
Ka taea e tatou te rapu tuatahi te take me te whakamahi i te otinga mai i te korero o runga ake nei. Mena kei a koe he reera pneumatic a-ringa, na i nga wa katoa ka whakatarewahia, me piu nga tangata katoa ki te mate, engari me tuku ano nga kaimahi papatohu, ki te whakatikatika ano, ki te whakatika ano i te kore me te whakatakotoranga taputapu; He maha nga take i kore ai te whakaritenga haerenga katinga i te waahi, he kakahu wehe te kakau takirere, ka eke te pehanga hau ki te paerewa. Tuatahi, whakatauhia te uara o te tuunga takirere, katahi ka whakatika i te whakaritenga haere o te waahi kati; Ko nga maru he hau - tuwhera, hau ranei - kati. Mena he hau hau, ka taea te kite i te pehanga pneumatic e mahi ana, karekau he raru ki te tuunga taputapu kore ine ine, hei taapiri, kaore he kaari kaari. Mena ko te hau e tuwhera ana, ka pakaru te paera pneumatic, me kati te paera. Ki te kore e katia, tera pea kaore he mea poke i te pereti ara iahiko hinu takirere; Mena kua katia ohorere te paera, ka pataihia mena he nui te pehanga o te papa taputapu, ara, ka taea e te putanga pehanga o te kairapu te whakatika i te pehanga mahi o te kati kua kati; Titiro ki te pehanga mahi o te paera pneumatic kaore e ranea, katahi ka titiro ki te paera mena he ahua kaari, he rerenga ranei, kua kati ano.
He tika ake te whakamatautau i te taputapu tuunga ahua tuatahi; Air valve: 1, he iti te kaha axial o te puna, ka taea te whakanui ake. 2, te tikanga mahi, kia nekehia atu te takirere ki te mahi i te whakamātautau pēhanga, tango i tenei whai wāhi ki te tirohia i te huru taatiraa o te takirere matua pehanga tiketike kuwaha takirere, me te mea he kino ki te matua takirere me te pehanga teitei kuwaha takirere.
3. Mena ka puta ano te keehi o te kore e kati, ka taea te tapahi i te takirere ki te tirotiro mehemea he mea paru kei te pehanga teitei o te kuaha o te puera ngakau. 4. 1. He tino nui te kaha axial o te puna, ka taea te whakaheke tika. 2.
3, ki te puta ano te ahuatanga kaore i mate, ka taea te tapahi i te takirere, tirohia mehemea he mea paru kei te ngakau takirere te pehanga teitei o te kuwaha 4, tirohia te pehanga pneumatic valve kaore i te he 5, tirohia mehemea he kino ki te kōpae takirere 6, tirohia mehemea he teitei ake te tohu kore o te takirere mena ka mahia te mahi i muri i te ahuatanga o te kati karekau i mate, Ka whakaarohia kia tirohia nga tawhā matua o te takirere kia kite mena he rereketanga kei waenganui i te whakaritea tawhā matua me te huru mahi tūturu.
