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

NTC是NegativeTemperatureCoefficient的縮寫，意思是負的溫度系數(shù)，泛指負溫度系數(shù)很大的半導體材料或元器件，所謂NTC熱敏電阻器就是負溫度系數(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體性質，因為在導電方式上完全類似鍺、硅等半導體材料。溫度低時，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。驅動液壓油泵和電動機是否具有的同軸度，對于液壓泵的使用壽命和能否達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)軸器進行驅動(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)接到驅動電機上，否則，就會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于工作條件，油溫也不能太高一如果如此的話，就應增設玲卻裝置，油箱必須仔細密封以預防油的泄漏和外部雜物的進入，同時出應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，故此進排氣裝置是必須的，一種便利的方法就是在油箱的高點處安裝一個空氣濾清器，由此預防任何塵粒從吸口進入。管道和聯(lián)接在裝配前液壓油泵上的所有保護塞都應去除掉，所有的管子和管接頭都應地進行清洗，吸油管道的規(guī)格應適應于泵上吸口螺紋(見表)其裝配必須具有氣密性。當使用吸口濾清器，尤其是吸油管道較長時，其管道應使用較大通徑的較為適宜，以便不超過先前陳述的負壓值。所有的回油和泄油管道應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.管端應該切成45。


一般，吸附所得露點與分子篩的溫度與水分攜帶量有關。通常，小于或等于3℃的露點可以使分子篩達到1%的水分攜帶量。為了制備干燥氣體，由能量計算所得的理論能量需求值是.4kWh/m3。實際中這個數(shù)值必須稍高，因為計算沒有把風扇或熱量損失考慮在內(nèi)。通過對比，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節(jié)注意點選用適合揚程的管道泵一般認為管道泵揚程小，則消耗功率小。但在實際上消耗功率是管道泵的流量成正比的，揚程小，則流量會增大，消耗功率也就隨之增大。當高揚程用以低揚程抽水時，電機會因過載而發(fā)熱甚至會燒毀電機。注意點管道泵進水口的深度適宜管道泵進水口入水太深極易造成吸入水池地步沉積雜物導致阻塞，進水口與水池底部距離應大于進水口直徑的1.5倍；若進水口入水太淺，會產(chǎn)生漩渦，影響進水，適宜深度為6~1mm。
