產(chǎn)品特色

• 應(yīng)用-動車真空系統(tǒng)真空度監(jiān)測

• ?

• ? ?正常狀態(tài)下，動車組真空集便器的真空系統(tǒng)的真空發(fā)生器會持續(xù)抽真空，車上的真空收集系統(tǒng)工作是會破掉真空，這樣

• 真空系統(tǒng)內(nèi)的真空會保持在一定值內(nèi)。

• ?

• ? ?但是在真空收集系統(tǒng)發(fā)生故障的時候，產(chǎn)生的真空會越來越大，以致會危害系統(tǒng)的安全，此時 beck的901真空壓力開關(guān)

• 就起到了警報作用，當(dāng)真空度上升到真空開關(guān)設(shè)定值的時候，901.21真空開關(guān)會發(fā)出報警信號，真空發(fā)生器停止工作；單真空度

• 下降到一定值的時候，901.21負(fù)壓開關(guān)報警信號消失，真空發(fā)生器正常工作。

• ?

• 型號- 901.21?
