VICKERS威格士V1020系列葉片泵4520V50A11-1AA22R單聯(lián)葉片泵
YVT-4機(jī)械故障聽診器有高靈敏探頭，可以查探出任何機(jī)械發(fā)出雜聲的部位。無論是活門震顫，挺桿震響，松動的活塞，齒輪和泵的各類震響，繼電器的螺線管操作的聲響，都可以清晰地查探出來。還可以檢測管道中液體流動與阻塞的狀態(tài)，各類馬達(dá)、內(nèi)燃機(jī)、柴油機(jī)、發(fā)動機(jī)、家用電器等運轉(zhuǎn)狀況以及工礦企業(yè)自動的運轉(zhuǎn)狀態(tài)。YVT-4機(jī)械故障聽診器廣泛適用于船舶、汽車、化工、冶金、機(jī)床、家用電器、機(jī)械等行業(yè)。主要用途：1)能對出壓縮機(jī)、齒輪箱發(fā)出的聲音進(jìn)行有效檢測;2)能迅速測出柴油機(jī)、汽缸、汽車發(fā)出的機(jī)械雜聲，并準(zhǔn)確地找出故障的部位3)能對各種發(fā)動機(jī)、馬達(dá)等發(fā)出的異常噪聲和雜聲進(jìn)行鑒別，從而避免事故發(fā)生。
FSB全氟塑料泵---是研發(fā)較早使用較為普片的一種離心式化工泵，其泵頭全部才用氟塑料模制而成，主要材料要--高分子材料、F26材質(zhì)、F46材質(zhì)、氟塑料合金材質(zhì)的。因材質(zhì)不同價格也誤差比較大。廠家在選擇時候容易混淆，因根據(jù)所輸送介質(zhì)類型，腐蝕性，介質(zhì)溫度，介質(zhì)濃度正確選用材料。此類泵一般用于進(jìn)出管道口徑要求相對較小，流量揚程要求較低的工礦中輸送化學(xué)流體。因泵頭全部采用氟塑料制造，因此機(jī)械強度相對比較弱，易開裂老化，在維修時必須拆卸泵的進(jìn)出口管道。
一般人對于帶式壓濾機(jī)的情況了解不是很多，而對于如何選用帶式壓濾機(jī)絮凝劑的人了解的更少，今天上海大張過濾設(shè)備給大家詳細(xì)說說。無機(jī)混凝劑的價格便宜，易獲得，他的缺點是渣渣比較多，而且受pH值影響大。高分子混凝劑的優(yōu)點是對于藥劑須求比低，操作也比較簡單，腐蝕性也比較弱，對于濾餅量的要求也比較低，將濾餅當(dāng)作燃料時，焚燒后的熱量比較高。不過在使用前，必須對污泥做試驗.帶式壓濾機(jī)操作過程中，使用混凝劑時應(yīng)該注意一下內(nèi)容：1.依據(jù)不同的脫水方法，帶式壓濾機(jī)采用的混凝劑也是各不相同的，一般情況下除了離心脫水使用高分子混凝劑外，其他的使用效果都差不多。泵循環(huán)攪拌是否均會影響混凝效果，使得脫水比較困難，應(yīng)當(dāng)適度調(diào)節(jié)下。多種混凝劑的投加需要注意順序。高分子混凝劑和助凝劑混合使用時，需要加助凝劑。在帶式壓濾機(jī)的生產(chǎn)過程中，鐵鹽形成的絮體密度比較大，藥劑量的需求也非常?。挥绕涫腔钚晕勰?，他的混凝效果相當(dāng)于高分子聚合混凝劑，使用的效果非常好，的缺點是腐蝕性比較強，對于貯藏和運輸都造成不便。若果帶式壓濾機(jī)的鐵鹽混凝劑較大時，則需要調(diào)節(jié)pH值，可用石灰來調(diào)節(jié)。
介質(zhì)粘度較大（大于65~1mm2/s）時，可考慮選用轉(zhuǎn)子泵或往復(fù)泵（齒輪泵、.螺桿泵）介質(zhì)含氣量75%，流量較小且粘度小于37.4mm2/s時，可選用旋渦泵。對啟動頻繁或灌泵不便的場合，應(yīng)選用具有自吸性能的泵，如自吸式離心泵、自吸式旋渦泵、氣動。知道泵選型的基本依據(jù)泵選型依據(jù)，應(yīng)根據(jù)工藝流程，給排水要求，從五個方面加以考慮，既液體輸送量、裝置揚程、液體性質(zhì)、管路布置以及操作運轉(zhuǎn)條件等流量是選泵的重要性能數(shù)據(jù)之一，它直接關(guān)系到整個裝置的的生產(chǎn)能力和輸送能力。
