Daim Ntawv Ceeb Toom (Handing)
• Tsis txhob siv DC bias rau lub piezoelectric buzzer;txwv tsis pub rwb thaiv tsev kuj yuav ua rau qis thiab cuam tshuam rau kev ua haujlwm.
• Tsis txhob muab qhov hluav taws xob siab tshaj qhov siv tau rau lub piezo electric buzzer.
• Tsis txhob siv lub piezoelectric buzzer sab nraum zoov.Nws yog tsim rau siv sab hauv tsev.Yog tias lub piezoelectric buzzer yuav tsum tau siv sab nraum zoov, muab nws nrog kev ntsuas dej tsis zoo;nws yuav tsis ua haujlwm ib txwm yog tias raug dej noo.
• Tsis txhob ntxuav lub piezoelectric buzzer nrog cov kuab tshuaj los yog cia cov roj nkag mus thaum ntxuav;cov kuab tshuaj uas nkag mus rau hauv nws yuav nyob twj ywm hauv lub sijhawm ntev thiab ua rau nws puas tsuaj.
• Cov khoom siv piezoelectric ceramic ntawm kwv yees li 100µm tuab yog siv rau hauv lub tshuab hluav taws xob suab ntawm lub buzzer.Tsis txhob nias lub tshuab hluav taws xob los ntawm lub suab tso tawm lub qhov txwv tsis pub cov khoom siv ceramic tuaj yeem tawg.Tsis txhob ntim cov piezoelectric buzzers yam tsis tau ntim.
• Tsis txhob siv lub zog txhua yam rau lub piezoelectric buzzer;Txwv tsis pub, rooj plaub yuav deform thiab ua rau kev ua haujlwm tsis raug.
• Tsis txhob tso cov khoom siv tiv thaiv los yog zoo li nyob rau pem hauv ntej ntawm lub suab tso lub qhov ntawm lub buzzer;txwv tsis pub lub suab siab yuav txawv thiab ua rau tsis ruaj tsis khov buzzer ua haujlwm.Xyuas kom tseeb tias lub buzzer tsis cuam tshuam los ntawm kev sawv nthwv dej lossis lwm yam.
• Nco ntsoov solder lub buzzer davhlau ya nyob twg ntawm 350 ° C max.(80W max.) (soldering hlau mus txawv tebchaws) nyob rau hauv 5 vib nas this siv ib tug solder uas muaj nyiaj.
• Tsis txhob siv lub piezoelectric buzzer rau lub sijhawm ntev uas muaj cov roj corrosive (H2S, thiab lwm yam) tshwm sim;txwv tsis pub cov khoom lossis lub tshuab hluav taws xob suab yuav corroded thiab ua rau kev ua haujlwm tsis raug.
• Ceev faj tsis txhob tso lub piezoelectric buzzer.
