臺(tái)灣Northman北部精機(jī)溢流閥MRF-02A-K-1,MRF-02B-K-1,MRF-02D-K-1

REXROTH力士樂電磁球閥的球體是彈性的。球體和閥座密封圈都采用金屬材料制造，密封比壓很大，依靠介質(zhì)本身的壓力已達(dá)不到密封的要求，必須施加外力。這種閥門適用于高溫高壓介質(zhì)。彈性球體是在球體內(nèi)壁的下端開一條彈性槽，而獲得彈性。當(dāng)關(guān)閉通道時(shí)，用閥桿的楔形頭使球體漲開與閥座壓緊達(dá)到密封。在轉(zhuǎn)動(dòng)球體之前先松開楔形頭，球體隨之恢復(fù)原原形，使球體與閥座之間出現(xiàn)很小的間隙，可以減少密封面的摩擦和操作扭矩。PVD涂層技術(shù)的新進(jìn)展顯示了涂層技術(shù)對(duì)提高刀具性能的巨大潛力和獨(dú)特優(yōu)勢，通過對(duì)涂層工藝參數(shù)的控制和對(duì)靶材、反應(yīng)氣體的調(diào)整，可不斷開發(fā)出新的高性能涂層，以滿足加工多樣性的需要。涂層技術(shù)將成為提高和改善刀具性能的捷徑，有著十分廣闊的應(yīng)用前景。不斷創(chuàng)新刀具結(jié)構(gòu)隨著制造業(yè)的高速發(fā)展，汽車工業(yè)、航天工業(yè)、模具工業(yè)等重點(diǎn)產(chǎn)業(yè)部門對(duì)切削加工不斷提出更高的要求，推動(dòng)著可轉(zhuǎn)位刀具的持續(xù)發(fā)展。為汽車線開發(fā)的專用成套刀具突破了傳統(tǒng)的按需供刀、閉門造刀的做法，成為革新加工工藝、提高加工效率、降低加工成本的重要工藝因素，發(fā)揮著重要的作用。

由于它可以借助于按鈕開關(guān)，行程開關(guān)，限位開關(guān)，壓力繼電器等發(fā)出的電信號(hào)進(jìn)行控制，一般在預(yù)先確定的時(shí)間內(nèi)運(yùn)行，電機(jī)不會(huì)超負(fù)荷。但如出現(xiàn)下列情況便可能導(dǎo)致超負(fù)荷：一是電源電壓低，得不到所需的轉(zhuǎn)矩，使電機(jī)停止轉(zhuǎn)動(dòng)；二是錯(cuò)誤地調(diào)定轉(zhuǎn)矩限制機(jī)構(gòu)，使其大于停止的轉(zhuǎn)矩，造成連續(xù)產(chǎn)生過大轉(zhuǎn)矩，使電機(jī)停止轉(zhuǎn)動(dòng)；三是斷續(xù)使用，產(chǎn)生的熱量積蓄，超過了電機(jī)的允許溫升值；四是因某種原因轉(zhuǎn)矩限制機(jī)構(gòu)電路發(fā)生故障，使轉(zhuǎn)矩過大；五是使用環(huán)境溫度過高，相對(duì)使電機(jī)熱容量下降。過去對(duì)電機(jī)進(jìn)行保護(hù)的辦法是使用熔斷器、過流繼電器、熱繼電器、恒溫器等，但這些辦法各有利弊。
