Rexroth力士樂(lè)順序閥A4VSO40DR-PPB13N00充液閥

R44A作為當(dāng)今廣泛使用的中低溫制冷劑，常應(yīng)用于冷庫(kù)、食品冷凍設(shè)備、船用制冷設(shè)備、工業(yè)低溫制冷、商業(yè)低溫制冷、交通運(yùn)輸制冷設(shè)備（冷藏車(chē)等）、冷凍冷凝機(jī)組、超市陳列展示柜等制冷設(shè)備。R44A是新裝制冷設(shè)備上替代氟利昂R22和R52的zui普遍的工業(yè)標(biāo)準(zhǔn)制冷劑（通常為低溫冷凍系統(tǒng)）。名稱(chēng)：R44A，HFC-44A分類(lèi)：混合物，混合制冷劑分子量：97.6摩爾質(zhì)量：97.6g/mol臨界溫度：72℃臨界壓力：3.7MPa臨界密度：.4842g/cm3沸點(diǎn)(11.3KPa):-46.1℃CAS編號(hào)：354-33-6/811-97-2/42-46-2液體密度（25℃）:1.45g/cm3沸點(diǎn)下蒸發(fā)潛能KJ/Kg：2.1比熱（25℃）Kj/(kg.k)：1.54破壞臭氧潛能值（ODP）：全球變暖系數(shù)值（GWP）：385等壓蒸氣比熱(3℃,11.3kPa):.21R47C制冷劑R47C是由R3R125和R134a按一定的比例混合而成的環(huán)保中高溫冷媒，使用于各種空調(diào)系統(tǒng)和非離心式制冷系統(tǒng)。


不經(jīng)常啟閉的銅內(nèi)螺紋球閥，也要定期轉(zhuǎn)動(dòng)手輪，對(duì)閥桿螺紋添加潤(rùn)滑劑，以防咬住。室外氧氣截止閥，要對(duì)閥桿加保護(hù)套，以防雨、雪、塵土銹污。如閥門(mén)系機(jī)械待動(dòng)，要按時(shí)對(duì)變速箱添加潤(rùn)滑油。要經(jīng)常保持氧氣截止閥的清潔。要經(jīng)常檢查并保持氧氣截止閥另部件完整性。如手輪的固定螺母脫落，要配齊、不能湊合使用，否則會(huì)磨園閥桿上部的四方，逐漸失去配合可靠性，乃至不能開(kāi)動(dòng)。不要依靠氧氣截止閥支持其它重物，不要在氧氣截止閥上站立。



在搪玻璃層臨近空間部位施焊時(shí)，應(yīng)將搪玻璃表面、罐口、管口蓋嚴(yán)，避免電焊渣飛濺，損壞搪玻璃面。搪玻璃設(shè)備的使用在使用中注意：1）嚴(yán)防任何金屬硬物掉進(jìn)容器，碰傷搪玻璃。盡量避免冷罐時(shí)加熱料，熱罐時(shí)加冷料。由于突然改變溫度，形成內(nèi)應(yīng)力，影響使用壽命。操作運(yùn)轉(zhuǎn)在使用夾套設(shè)備時(shí)，應(yīng)徐徐進(jìn)行加壓、升溫，一般先通入.1MPa（表壓）壓力蒸汽，保持15分鐘后，再緩緩升壓、升溫（升壓速度以每1分鐘升.1MPa壓力為宜），在到罐的操作壓力為止，不管加熱或冷卻應(yīng)在允許溫度范圍內(nèi)進(jìn)行，我公司設(shè)備使用溫度～2℃，溫差熱沖擊12℃，冷沖擊11℃。
