VICKERS威格士中壓變量葉片泵2520VQ12A11-1AA22RVQ系列單泵
由于親水性較濾紙小，電滲作用小，電泳時大部分電流是由樣品傳導(dǎo)的，所以分離速度快，電泳時間短，一般電泳45~6分鐘即可，加上染色、脫色，整個電泳完成僅需9分鐘左右。靈敏度高，樣品用量少，血清蛋白電泳僅需2l血清，故常用于檢測在病理情況下微量異常蛋白質(zhì)的改變。。某些蛋白質(zhì)在紙上電泳不易分離，如胎兒甲種球蛋白、溶菌酶、胰島素、組蛋白等用醋酸纖維素薄膜電泳能較好地分離。易保存，易定量。醋酸纖維素薄膜電泳染色后，經(jīng)冰乙酸、乙醇混合液或其他溶液浸泡后可制成透明的干板，有利于掃描定量及長期保存。
鋁合金產(chǎn)品的某些工藝處理及檢驗項目，如果需方?jīng)]有要求，供方則不提供，如此可造成產(chǎn)品性能有顯著的差異。如美鋁產(chǎn)品中的可熱處理強化合金系列均經(jīng)過內(nèi)應(yīng)力消除工藝處理，通過超聲波探傷檢驗、光譜分析、半導(dǎo)彎曲試驗、顯微腐蝕試驗、電磁（渦流）測試以及開裂敏感性試驗等項目，確保美鋁產(chǎn)品在市場的各個方面均出類拔萃。變形鋁或鋁合號中的數(shù)字只代表其純度或某些合金化學(xué)元素的大平均百分含量。即使是化學(xué)成分含量，同一牌號的產(chǎn)品因其所依據(jù)的生產(chǎn)標準不同以及生產(chǎn)批次不同而有所不同。.為什么鋁合金陽極氧化零件不能用在堿性環(huán)境中？答:鋁合金陽極氧化生成氧化膜的成分是氧化鋁。膜層致密，耐磨。而氧化鋁是兩性物質(zhì)，會和堿反應(yīng)使膜層溶解。.不同型號的鋁材陽極氧化后顏色為什么不一致？答:不同型號的鋁材合金成分及含量也是不同的。鋁的純度直接影響氧化膜的透明性，合金中的元素SMn、Cr、Mg會影響氧化膜的發(fā)色性，從而影響到氧化后膜層的顏色。.鋁材陽極氧化后有明顯晶斑？答:出現(xiàn)晶斑是由于鋁合金在擠壓工藝不當及熱處理不規(guī)范的情況下，合金元素發(fā)生偏析偏聚，從而引發(fā)晶間腐蝕、終沉淀出白色絮狀A(yù)L（OH）3，干涸后形成晶斑。
GBL型立式濃硫酸離心泵的概述：GBL型立式濃硫酸離心泵，采用濃硫酸專用鑄鐵、碳鋼二種材料和水力模型進行優(yōu)化設(shè)計而成。是理想的新一代化工泵。該泵軸封采用外裝式優(yōu)質(zhì)機械密封，動、靜環(huán)采用新型硬質(zhì)合金或陶瓷制成，耐磨損、無泄漏、使用壽命長。離心泵一般由電動機帶動，在啟動泵前，泵體及吸入管路內(nèi)充滿液體。當葉輪高速旋轉(zhuǎn)時，葉輪帶動葉片間的液體一道旋轉(zhuǎn)，由于離心力的作用，液體從葉輪中心被甩向葉輪外緣（流速可增大至15～25m/s），動能也隨之增加。
一級保養(yǎng)工作是在例行保養(yǎng)得基礎(chǔ)上進行的，重點工作內(nèi)容是潤滑、緊固并檢查各有關(guān)部位及其清潔工作.二級保養(yǎng)工作以檢查、調(diào)整為重點。具體要檢查發(fā)動機、離合器、變速器、傳動構(gòu)件、轉(zhuǎn)向和制動構(gòu)件。三級保養(yǎng)重點是檢測、調(diào)整、排除故障隱患及平衡各部件的磨損程度。要對影響設(shè)備使用性能的部位及有故障征兆的部位進行診斷檢測和狀態(tài)性檢查，進而完成必要的更換、調(diào)整及故障排除等工作。換季保養(yǎng)是指包裝設(shè)備每年入夏和入冬前應(yīng)重點對燃潤系統(tǒng)、液壓系統(tǒng)、冷卻系統(tǒng)和啟動系統(tǒng)等構(gòu)件的檢測和修復(fù)。
