BURKERT8605型控制器,寶德2400型伺服閥,德國(guó)BURKERT伺服閥
BURKERT8605型控制器,底面與高溫燃燒產(chǎn)物直接接觸，在氣閥開(kāi)啟期間還承受著高溫（900～1000°C）和具有腐蝕性氣體的高速（達(dá)600m/s）沖刷，氣閥溫度高達(dá)700～800°C，在閥盤與閥桿過(guò)渡圓弧中段，溫度也有600～700°C，排氣閥工作溫度分布如圖1-1所示。材料發(fā)生熱變形。過(guò)高的溫度會(huì)使金屬材料的機(jī)械降低，材料發(fā)生熱變形。當(dāng)閥面密封不嚴(yán)時(shí)，就會(huì)引起高溫度燃?xì)鈱?duì)閥面的燒損。氣閥落座時(shí)，閥與閥座的慣性力和彈簧作用力的共同作用下，還承受著相當(dāng)大的沖擊性交變載荷，在氣閥出現(xiàn)跳動(dòng)或氣閥間隙增大時(shí)，這種載荷會(huì)明顯增加。閥與閥座的撞擊，容易形成密封面的變形和嚴(yán)重的磨損。因船用柴油機(jī)大部分多為增壓柴油機(jī)，由于進(jìn)氣道內(nèi)的空氣壓力阻止了從氣閥導(dǎo)管中獲得滑油的可能，因此，金屬之間易發(fā)生干摩擦。但在般柴油機(jī)的氣閥以及增壓柴油機(jī)的排氣閥座合金面間總會(huì)布有層滑油或煙油等潤(rùn)滑物。此外，閥桿與導(dǎo)管間也會(huì)發(fā)生磨損，閥桿頂端受搖臂的撞擊與磨損。
