德國Beck品牌 901.21111M4真空壓力開關(guān) 真空集便器定制壓力開關(guān)

產(chǎn)品介紹

產(chǎn)品描述

• 生產(chǎn)廠家：德國Beck公司

• 產(chǎn)品名稱：真空壓力開關(guān)
  

• 產(chǎn)品型號(hào)：901.21111M4

• 采購號(hào)：16645-0061

• 產(chǎn)品類型：機(jī)械式壓力開關(guān)

產(chǎn)品效果圖

產(chǎn)品特色

• 經(jīng)典應(yīng)用-動(dòng)車真空系統(tǒng)真空度監(jiān)測(cè)

•  

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

• 真空系統(tǒng)內(nèi)的真空會(huì)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(shí)候，產(chǎn)生的真空會(huì)越來越大，以致會(huì)危害系統(tǒng)的安全，此時(shí) beck的901真空壓力開關(guān)

• 就起到了警報(bào)作用，當(dāng)真空度上升到真空開關(guān)設(shè)定值的時(shí)候，901.21真空開關(guān)會(huì)發(fā)出報(bào)警信號(hào)，真空發(fā)生器停止工作；單真空度

• 下降到一定值的時(shí)候，901.21負(fù)壓開關(guān)報(bào)警信號(hào)消失，真空發(fā)生器正常工作。

•  

• 推薦型號(hào)- 901.21
