Rexroth力士樂電控減壓閥A10VSO71DFR1/31R-VPA12N00液壓單元

NTC是NegativeTemperatureCoefficient的縮寫，意思是負(fù)的溫度系數(shù)，泛指負(fù)溫度系數(shù)很大的半導(dǎo)體材料或元器件，所謂NTC熱敏電阻器就是負(fù)溫度系數(shù)熱敏電阻器。它是以錳、鈷、鎳和銅等金屬氧化物為主要材料，采用陶瓷工藝制造而成的。這些金屬氧化物材料都具有半導(dǎo)體性質(zhì)，因?yàn)樵趯?dǎo)電方式上完全類似鍺、硅等半導(dǎo)體材料。溫度低時(shí)，這些氧化物材料的載流子（電子和孔穴）數(shù)目少，所以其電阻值較高；隨著溫度的升高，載流子數(shù)目增加，所以電阻值降低。驅(qū)動(dòng)液壓油泵和電動(dòng)機(jī)是否具有的同軸度，對(duì)于液壓泵的使用壽命和能否達(dá)到令人滿意的性能具有很大的影響，泵軸絕不能承受徑向或軸向力，必須通過柔性聯(lián)軸器進(jìn)行驅(qū)動(dòng)(注意必須給聯(lián)軸器制造廠家提出特殊要求或訂貨)泵不能直接聯(lián)接到驅(qū)動(dòng)電機(jī)上，否則，就會(huì)引起軸密封和軸承的過早損壞。貯油箱油箱的體積容量必須適應(yīng)于工作條件，油溫也不能太高一如果如此的話，就應(yīng)增設(shè)玲卻裝置，油箱必須仔細(xì)密封以預(yù)防油的泄漏和外部雜物的進(jìn)入，同時(shí)出應(yīng)能夠使其自由的呼吸，由于工作循環(huán)的變化以及溫度的變化，從而引起油的體積變化，故此進(jìn)排氣裝置是必須的，一種便利的方法就是在油箱的高點(diǎn)處安裝一個(gè)空氣濾清器，由此預(yù)防任何塵粒從吸口進(jìn)入。管道和聯(lián)接在裝配前液壓油泵上的所有保護(hù)塞都應(yīng)去除掉，所有的管子和管接頭都應(yīng)地進(jìn)行清洗，吸油管道的規(guī)格應(yīng)適應(yīng)于泵上吸口螺紋(見表)其裝配必須具有氣密性。當(dāng)使用吸口濾清器，尤其是吸油管道較長時(shí)，其管道應(yīng)使用較大通徑的較為適宜，以便不超過先前陳述的負(fù)壓值。所有的回油和泄油管道應(yīng)該排列得不致于使回油立刻返回到泵的吸口。所有管道必須聯(lián)接在低于低油面(約Scm》足夠深處以避免泡沫和噪聲，并能夠得到充分的冷卻.管端應(yīng)該切成45。


一般，吸附所得露點(diǎn)與分子篩的溫度與水分?jǐn)y帶量有關(guān)。通常，小于或等于3℃的露點(diǎn)可以使分子篩達(dá)到1%的水分?jǐn)y帶量。為了制備干燥氣體，由能量計(jì)算所得的理論能量需求值是.4kWh/m3。實(shí)際中這個(gè)數(shù)值必須稍高，因?yàn)橛?jì)算沒有把風(fēng)扇或熱量損失考慮在內(nèi)。通過對(duì)比，不同類型的干燥氣體發(fā)生器的特定能耗就可以被確定。一般來說，除濕氣體干燥的能耗在.4kWh/kg～.12kWh/kg之間，這要根據(jù)物料和初始水分含量而變化。



不容忽視的管道泵安裝的一些細(xì)節(jié)注意點(diǎn)選用適合揚(yáng)程的管道泵一般認(rèn)為管道泵揚(yáng)程小，則消耗功率小。但在實(shí)際上消耗功率是管道泵的流量成正比的，揚(yáng)程小，則流量會(huì)增大，消耗功率也就隨之增大。當(dāng)高揚(yáng)程用以低揚(yáng)程抽水時(shí)，電機(jī)會(huì)因過載而發(fā)熱甚至?xí)龤щ姍C(jī)。注意點(diǎn)管道泵進(jìn)水口的深度適宜管道泵進(jìn)水口入水太深極易造成吸入水池地步沉積雜物導(dǎo)致阻塞，進(jìn)水口與水池底部距離應(yīng)大于進(jìn)水口直徑的1.5倍；若進(jìn)水口入水太淺，會(huì)產(chǎn)生漩渦，影響進(jìn)水，適宜深度為6~1mm。
