產品特色

• 應用-動車真空系統真空度監測

• ?

• ? ?正常狀態下，動車組真空集便器的真空系統的真空發生器會持續抽真空，車上的真空收集系統工作是會破掉真空，這樣

• 真空系統內的真空會保持在一定值內。

• ?

• ? ?但是在真空收集系統發生故障的時候，產生的真空會越來越大，以致會危害系統的安全，此時 beck的901真空壓力開關

• 就起到了警報作用，當真空度上升到真空開關設定值的時候，901.21真空開關會發出報警信號，真空發生器停止工作；單真空度

• 下降到一定值的時候，901.21負壓開關報警信號消失，真空發生器正常工作。

• ?

• 型號- 901.21?
