Isivinini sokufaka uchungechunge esilawula i-valve yokumisa i-bidirectional BLF-10

Inzwa ye-piezoelectric kanye ne-strain-based sensor inezici ezihlukile ngokusobala.

Inzwa yamandla e-Piezoelectric yakhiwe ngezingcezu zekristalu ye-piezoelectric, ezikhiqiza ukushaja lapho zingaphansi kwamandla acindezelayo. Ngokuvamile, i-electrode ifakwa phakathi kwezingcezu ezimbili, edonsa ukushaja okwenziwe, futhi igobolondo elizungezile lisebenza njenge-electrode. Izinga eliphezulu lekristalu negobolondo lenzwa ye-piezoelectric liphezulu kakhulu, futhi libaluleke kakhulu ngekhwalithi yokulinganisa (umugqa, izici zokuphendula) zenzwa yamandla.

Ukuthi kufanele usebenzise inzwa yamandla ecindezelwe noma esekelwe kumfutho incike kulolo hlelo lokusebenza. Izinzwa ze-Piezoelectric zikhethwa ezinhlelweni ezilandelayo:

Isikhala sokufaka inzwa sikhawulelwe.

Isilinganiso samandla amancane anomthwalo omkhulu wokuqala

Ibanga elibanzi lokulinganisa

Ukulinganisa ekushiseni okuphezulu kakhulu

Ukuzinza kokulayisha ngokweqile

Amandla aphezulu

Kokulandelayo, sizokwethula izinkambu zohlelo lokusebenza ezijwayelekile ngokuningiliziwe futhi sikunikeze umhlahlandlela wokukhethwa kwezinzwa.

Izinkambu zokufaka izicelo zezinzwa ze-piezoelectric;

1. Isikhala sokufaka inzwa sinqunyelwe.

Izinzwa ze-Piezoelectric zihlangene kakhulu-isibonelo, uchungechunge lwe-CLP luphakeme ngo-3 kuya ku-5 mm kuphela (kuya ngebanga lokulinganisa). Ngakho-ke, le nzwa ifaneleka kakhulu ukuhlanganiswa nezakhiwo ezikhona. Izinzwa zinekhebula elihlanganisiwe, ngenxa yokuthi azikwazi ukufaka amapulaki, ngakho ubude besakhiwo buphansi kakhulu. Inzwa inabo bonke osayizi bomucu, ukusuka ku-M3 kuya ku-M14. Ukuphakama okuphansi kwesakhiwo kudinga ukuthi amandla endaweni yenzwa angasakazwa ngokulinganayo.

2. Isilinganiso samandla amancane esinomthwalo omkhulu wokuqala

Uma kusetshenziswa amandla, inzwa ye-piezoelectric ikhiqiza ukushaja kagesi. Nokho, inzwa ingaphansi kwamandla adlula isilinganiso sangempela, isibonelo, ngesikhathi sokufakwa. Ishaja ekhiqiziwe ingase ibe yi-short-circuited, ibeka isignali ekufakweni kwe-amplifier yokushaja ibe yiziro. Ngale ndlela, ububanzi bokulinganisa bungalungiswa ngokuvumelana namandla angempela okufanele akalwe. Ngakho-ke, ngisho noma umthwalo wokuqala uhluke kakhulu kumandla alinganisiwe, ukulungiswa kokulinganisa okuphezulu kungaqinisekiswa. Ama-amplifiers eshaja asezingeni eliphezulu njenge-CMD600 angaqhubeka nokulungisa ububanzi bokulinganisa ngesikhathi sangempela, ngaleyo ndlela asekele lezi zinhlelo zokusebenza.

3. Ibanga elibanzi lokulinganisa

Izinzwa ze-Piezoelectric nazo zinezinzuzo kuma-multi-stage. Okokuqala, lapho kusetshenziswa amandla amakhulu ekuqaleni. Lungisa iketango lokulinganisa le-piezoelectric ngokufanele. Isigaba sesibili sibandakanya ukulandelela amandla, okungukuthi, isilinganiso sokushintsha kwamandla amancane. Ukuzuza emisebenzini ekhethekile yenzwa ye-piezoelectric, okuhlanganisa ukususa ngokomzimba isignali ngokokufaka kwe-amplifier yokushaja. Okokufaka kwe-amplifier yokushaja kungasethwa ku-zero futhi ububanzi bokulinganisa bungalungiswa ukuze kuqinisekiswe ukulungiswa okuphezulu.
