這時候的水泵是在高效區(qū)工作。所以，水泵安裝時要注意以下幾點：1）水泵的安裝位置應(yīng)滿足允許吸上真空高度的要求，基礎(chǔ)必須水平、穩(wěn)固，保證動力機械的旋轉(zhuǎn)方向與水泵的旋轉(zhuǎn)方向一致。2）水泵和動力機采用軸聯(lián)接時，要保證軸心在同一直線上，以防機組運行時產(chǎn)生振動及軸承單面磨損；3）若采用膠帶傳動，則應(yīng)使軸心相互平行，膠帶輪對正。4）若同一機房內(nèi)有多臺機組，機組與機組之間，機組與墻壁之間都應(yīng)有800mm以上的距離。5）水泵吸水管必須密封良好，且盡量減少彎頭和閘閥，加注引水時應(yīng)排盡空氣，運行時管內(nèi)不應(yīng)積聚空氣，要求吸水管微呈上，斜與水泵進水口聯(lián)接，進水口應(yīng)有一定的淹沒深度。6）水泵泵基礎(chǔ)上的預(yù)留孔，應(yīng)根據(jù)水泵的尺寸澆注。磁力泵↑磁力泵→magneticdrivepump磁力泵，泵軸、內(nèi)磁轉(zhuǎn)子被泵體、隔離套完全封閉，從而徹底解決了“跑、冒、滴、漏”問題，消除了煉油化工行業(yè)易燃、易爆、有毒、有害介質(zhì)通過泵密封泄漏的安全隱患。磁力泵出來正常的安裝，浙江校準(zhǔn)隔膜壓力表的作用，開機，運行及關(guān)機操作之外，還有考慮磁力泵本身技術(shù)參數(shù)，浙江校準(zhǔn)隔膜壓力表的作用，以及輸送介質(zhì)的特點等因素。磁力泵輸送介質(zhì)的密度不大于1300kg/m3，浙江校準(zhǔn)隔膜壓力表的作用，粘度不大于30×10-6m3/S的不含鐵磁性和纖維的液體。Ham上海震揚光電壓力表有哪些型號。浙江校準(zhǔn)隔膜壓力表的作用</p><div

在石化生產(chǎn)中，所謂壓力是指由氣體或液體均勻垂直地作用于單位面積上的力。特別是在石化生產(chǎn)過程中，經(jīng)常會遇到壓力和真空度的測量，比大氣壓力高很多的高壓、超高壓和比大氣壓力低很多的真空測量。壓力表的安裝應(yīng)用安裝方式：徑向指壓力表的連接口徑與表盤成丨型，為直接安裝。軸向指壓力表的連接口徑與表盤成T型。還分為中軸和偏軸(下軸)安裝。連接方式：螺紋連接有M20×；G1/2；G3/8;NPT1/2；NPT1/4(其他)。法蘭連接根據(jù)客戶要求制造。儀表固定方式：直接安裝前帶邊安裝后帶邊安裝U型卡子安裝測量范圍的選擇測量穩(wěn)定的壓力時，正常操作壓力值應(yīng)在儀表測量范圍上限值的1/3---2/3；測量脈動壓力(如:泵、壓縮機和風(fēng)機等出口處壓力)時，正常操作壓力值應(yīng)在儀表測量范圍上限值的1/3~1/2；側(cè)量高、中壓力時，正常操作壓力值不應(yīng)超過儀表測量范圍上限值的1/2。按照使用環(huán)境和測量介質(zhì)的性質(zhì)選擇在大氣腐蝕性較強、粉塵較多和易噴淋液體等環(huán)境惡劣的場合，應(yīng)根據(jù)環(huán)境條件，選擇合適的外殼材料及防護等級。A、對一般介質(zhì)的測量壓力在-40kPa---+40kPa時，宜選用膜盒壓力表。壓力在+40kPa以上時，一般選用彈簧管壓力表或波紋管壓力計。
