Ko te mahi a te puera mana e mohio ana ki te whakahaere kaore e taea te whakapae. I roto i nga waahi maha e hiahiatia ana te mana whakahaere, ka hiahiatia te waahi whakahaere ki te waahi ka puta he korenga ki te whakarite kia kore he aitua iti ranei i roto i te mahi, na reira ka hangaia te waahi whakahaere ki te mohio ki nga tikanga whakamarumaru o te hau kore-haumaru, te tapahi hiko, me te tapahi tohu. He tino ngawari tenei mo nga hiko whakahaere hiko. Ina tapahia te tohu, ka taea te kati kia rite ki te whakatakotoranga o tetahi waahanga whakahaere. Tetahi waahi tuwhera me te pupuri, a ka motuhia te hiko, ka mutu ka mutu i te waahi he, ka taea ranei e te kaitahuri hiko me te taputapu tautuhi te whakahaere i te tuunga takirere kia tino tuwhera, kia kati ranei.
Mo te puera mana pneumatic, he uaua ake te ahuatanga, no reira ka korerohia e matou te tikanga e toru nga wehenga o te mana whakahaere pneumatic. I te nuinga o te korero, ka whiriwhiria e tatou he puera mana o te membrane pneumatic, me whakatau tuatahi mena ka tuwhera te hau, ka kati ranei te hau. Koinei te waahi tiaki i te wa ka tapahia te hau. Ki te hiahia te tukanga kia whakatuwherahia te takirere ina tapahia te hau, tohua te tuwhera (ka kati te hau). ) Patohia te paera mana, ki te kore, tohua te momo katia (tuwhera-rangi) te momo mana whakahaere. He otinga taratara noa tenei. Mena ka hiahiatia e te tukanga te whakamarumaru e toru-waahi mo te hau, te mana, me te tohu, me whakauru te reera whakahaere ki etahi taputapu hei hanga i tetahi punaha whakamarumaru ki te whakatutuki i nga whakaritenga whakahaere. Ko enei taputapu kei roto i te nuinga o te waa pupuri me nga reera solenoid. , Tane hau, me etahi atu. Ko enei e rua nga kaupapa e mau ana i te waahi o te mana whakahaere o te diaphragm pneumatic kotahi, me te rua o te mana whakahaere pneumatic.
1. Ko te kaupapa mana o te membrane pneumatic (kei te whakauruhia te waahi whakahaere ki te hiko-pneumatic valve positioner)
Ko te nuinga o tenei kaupapa ko te puera mana pneumatic, te hiko-pneumatic valve positioner, te mate hiko (tohu) whakatairite, te hiko hiko kotahi te mana hiko solenoid takirere, pneumatic reining valve, valve position signal returner, etc. Ko tana kaupapa mahi e whai ake nei:
1. Tapahia te puna o te hau: Ka kore te puna hau o te punaha whakahaere (kua ngaro te hau), ka kati aunoa te puera pupuri pneumatic ki te maukati i te pehanga tohu whakaputa o te tuunga i roto i te ruuma diaphragm o te puera mana pneumatic, te pehanga tohu whakaputa me te kaha tauhohenga i hangaia e te puna o te puna mana whakahaere i te toenga o te wahanga, ko te tuunga o te waahi o te waahi o te hikoi ka mau tonu ki te waahi o te mana o te hau. Me whakatu te takirere pupuri kia timata ina he iti iho i te iti rawa o te uara o te tuku hau.
2. Whakamutua te hiko: ka ngaro te hiko o te punaha whakahaere (ka ngaro te mana), ko te ngaohiko whakaputa o te ngaronga hiko (tohu) kaiwhakariterite e whakahaere ana i te hiko hiko kotahi e whakahaere ana i te hikohiko hiko hiko ka ngaro, ka ngaro te mana hiko, ka ngaro te mana hiko, me te hikohiko kotahi te hikohiko Ko te reera i roto i te reversing o te puna o te reera, ko te reera mahi i roto i te reversing o te puna whakamuri. kua whakakorehia te ruma diaphragm o te paera pupuri pneumatic, kua kati te paera pupuri pneumatic, a ka mauhia te pehanga tohu whakaputa o te tuunga i roto i te puera mana pneumatic I roto i te ruma diaphragm, ka taurite te pehanga tohu whakaputa me te kaha o te urupare i hangaia e te puna valve mana, me te noho tonu o te waahi o te waahi o te mana o te pneumatic.
3. Momotu tohu: Ka kore te tohu o te punaha whakahaere (te ngaro o te tohu), i muri i te kitenga o te mate hiko (tohu), ka tapahia e ia te tohu ngaohiko o te hiko hiko hiko hiko hiko, ka ngaro te mana hiko o te hiko hiko hiko. Ko te riipene hiko i roto i te hiko hiko hiko whakamuri whakamuri hiko e paheke ana i raro i te mahi a te puna hokinga mai. Ka huri te paera solenoid ki te whakaheke i te pehanga i roto i te ruuma diaphragm o te paera pupuri pneumatic, a ka kati te paera pupuri pneumatic ki te kati i te pehanga tohu whakaputa o te tuunga. I roto i te ruma diaphragm o te paera mana pneumatic, ka taurite te pehanga tohu whakaputa me te kaha o te urupare i hangaia e te puna o te puna mana whakahaere, a ka noho tonu te waahi o te waahi o te mana o te pneumatic ki te waahi he.
Ko te tohu urupare tuunga ka tukuna mai e te kaikawe tohu tohu tuunga.
Nga painga o tenei kaupapa: Ina whakahohea te whakamarumaru 'toru wehenga', ka tere te urupare a te punaha, ka tere te mahi. He iti noa te utu katoa.
Ko nga huakore o tenei kaupapa: Ko te solenoid valve kua utua mo te wa roa, e pa ana ki tona oranga mahi. He maha nga taputapu, he uaua ake te whakaurunga me te patuiro. Ko nga urupare tuunga o te takirere me whakauru ki te whakahoki tohu tohu tuunga, he uaua ake i te wa e mau ana ki te wira ringaringa.
