Rexroth力士樂電液比例先導溢流閥A10VS045DR/31RPPA12N00液控單向閥
流量或壓力調節系統排污前，應先將自動切換到手動，保證調節閥的開度不變。對于差壓變送器，排污前先將三閥組正負取壓閥關死。排污閥下放置容器，慢慢打開正負導壓管排污閥，使物料和污物進入容器，防止物料直接排入地溝，否則，一來污染環境，二來造成浪費。由于閥門質量差，排污閥門開關幾次以后會出現關不死的問題，應急措施是加盲板，保證排污閥處于不泄漏，以免影響測量度。開啟三閥組正負取壓閥，擰松差壓變送器本體上排污（排氣）螺絲進行排污，排污完成擰緊螺絲。
MVR蒸發選型依據離心壓縮熱泵應用領域：離心壓縮熱泵升溫8-11℃左右:用于無沸點升高大的物料。如低濃度的溶液熱泵是一種特殊的產熱機器熱泵是一種特殊的產熱機器，它可將存在于周圍環境的熱量（如水和空氣的熱量）以及工業生產過程中排棄的大量低品位的余熱加以回收利用，故日益引起人們的關注.機械壓縮熱泵是使用為廣泛的一類熱泵.本文擬對機械壓縮熱泵，討論高、低溫熱源溫度對熱泵循環操作性能系數的影響，并選擇普遍使用的制冷劑R22及R12的替代物R134ａ為工質，分析比較兩種制冷劑循環的操作性能。
材料試驗機的引伸計是用于測量拉伸試樣的微量變形，或者研究構件在外力作用下的線性變形所采用的儀器。引伸計一般由三部分組成。感受變形部分用來直接與試樣表面接觸，以感受試樣的變形。傳遞和放大部分把所感受的變形加以放大的機構。指冶部分指示或記錄變形大小的機構，有機械式和光學式的兩種。應變式位移傳感器主要甶粘貼有應變片的彈性元件組成。在小應變條件下，彈性元件上的應變與所受外力成正比，也與彈性元件的變形成正比。
一些行業則分別發展了適應本行業要求的連續操作干燥器，如紡織、造紙行業的滾筒干燥器。世紀初期，乳品生產開始應用噴霧干燥器，為大規模干燥液態物料提供了有力的工具。年代開始，隨著流化技術的發展，高強度、高生產率的沸騰床和氣流式干燥器相繼出現。而冷凍升華、輻射和介電式干燥器則為滿足特殊要求提供了新的手段。年代開始發展了遠紅外和微波干燥器。干燥過程需要消耗大量熱能，為了節省能量，某些濕含量高的物料、含有固體物質的懸浮液或溶液一般先經機械脫水或加熱蒸發，再在干燥器內干燥，以得到干的固體。
