Rexroth力士樂高低壓變量葉片泵A4VSO125DR/22R-PPB13N00柱塞泵

流量或壓力調(diào)節(jié)系統(tǒng)排污前，應(yīng)先將自動切換到手動，保證調(diào)節(jié)閥的開度不變。對于差壓變送器，排污前先將三閥組正負(fù)取壓閥關(guān)死。排污閥下放置容器，慢慢打開正負(fù)導(dǎo)壓管排污閥，使物料和污物進(jìn)入容器，防止物料直接排入地溝，否則，一來污染環(huán)境，二來造成浪費(fèi)。由于閥門質(zhì)量差，排污閥門開關(guān)幾次以后會出現(xiàn)關(guān)不死的問題，應(yīng)急措施是加盲板，保證排污閥處于不泄漏，以免影響測量度。開啟三閥組正負(fù)取壓閥，擰松差壓變送器本體上排污（排氣）螺絲進(jìn)行排污，排污完成擰緊螺絲。


一般每個傳感器將會有兩個溫度范圍，分別是工作范圍和補(bǔ)償范圍。補(bǔ)償范圍包含在工作范圍之內(nèi)。工作范圍是指在這個范圍內(nèi)，傳感器通電后可以暴露在介質(zhì)中而不會發(fā)生損壞。這并不表示當(dāng)處于補(bǔ)償范圍以外的時候其性能也能達(dá)到標(biāo)稱的規(guī)格(溫度系數(shù))。補(bǔ)償范圍一般是在工作范圍之內(nèi)的一段更狹窄的范圍。在這個范圍內(nèi)，傳感器確?？梢赃_(dá)到標(biāo)稱的規(guī)格。溫度的改變通過兩種方法影響傳感器，其一是造成零點(diǎn)漂移，其二是影響整個量程的輸出。



不銹鋼反應(yīng)釜以其優(yōu)良的耐腐蝕性能和較低的價格，贏得越來越多客戶的喜愛和信賴；因此在攪拌與反應(yīng)釜結(jié)合處的密封的選擇對于密封效果、使用安全、節(jié)約成本等都顯得特別重要，現(xiàn)對如何選擇合適的密封形式做出如下建議：1.首先要明確密封選擇的依據(jù)：是釜內(nèi)的工作壓力，第二是工作物料的性質(zhì)。還有一個就是設(shè)備的工作溫度。其次要明確不銹鋼反應(yīng)釜所用密封的類別：反應(yīng)釜所用密封即通常所說的軸封有兩類，是填料密封，第二是機(jī)械密封，機(jī)械密封又分為單機(jī)封（即單端面機(jī)械密封）和雙機(jī)封（即雙端面機(jī)械密封），單機(jī)封全套還包括水夾套，雙機(jī)封則較為復(fù)雜，除水夾套（必須有循環(huán)冷卻水）外，還包括配套的支架、平衡罐等。如何選擇合適的密封：在常溫常壓，物料沒有揮發(fā)性也不易燃易爆的使用條件下，要選擇填料密封；在壓力小于4公斤，物料的易揮發(fā)性和易燃易爆性一般的使用條件下，就要選擇單機(jī)封；在工作壓力超過4公斤（但要小于1公斤），物料的易揮發(fā)性和易燃易爆性很強(qiáng)的使用條件下，則必須選擇雙機(jī)封。各種密封的優(yōu)缺點(diǎn)：填料密封價格便宜，但只適合普通的使用條件和物料；單機(jī)封價格適中，可以在大多數(shù)使用條件下通用；雙機(jī)封價格貴，但在苛刻的工作條件下必須使用。
