VICKERS威格士V系列雙泵4520V50A9-1AA22R齒輪泵



RX系列油密封式旋塞閥上世紀八十年代，我國燃氣主要是人工煤制氣，蝶閥人工煤制氣中有較多的雜質和煤氣膠，原來傳統(tǒng)使用的單閘板契式水閘閥越來越不能適應燃氣工況的需要，這類閥門普遍存在關不嚴和閥桿咬死的問題，我們參考日本技術研制而成的RX系列燃氣用油密封式旋塞閥，解決了關不嚴和閥桿咬死的問題。RZ系列燃氣用平行雙閘板閘閥隨著燃氣事業(yè)的發(fā)展和煤氣廠的紛紛建立，需要較大甚至特大公稱通徑的燃氣專用閥門，RZ系列燃氣用平行雙閘板閘閥針對人工煤氣形成的問題給予一一解決，大通徑達16mm。
釜體外裝有桶型碳化硅爐芯，電爐絲穿于爐芯中，其端頭由爐殼側下部穿出，通過接線螺柱，橡套電纜與控制器相連。*釜蓋上裝有壓力表，爆破膜安全裝置，汽液相閥，溫度傳感器等，便于隨時了解釜內的反應情況，調節(jié)釜內的介質比例，并確保安全運行。*聯(lián)軸器主要由具有很強磁力的一對內、外磁環(huán)組成，中間有承壓的隔套。攪拌器由伺服電機通過聯(lián)軸器驅動?？刂扑欧姍C的轉速，便可達到控制攪拌轉速的目的。*隔套上部裝有測速線圈，連成一體的攪拌器與內磁環(huán)旋轉時，測速線圈便產生感應電動勢，該電勢與攪拌轉速相應，該電勢傳遞到轉速表上，便可顯示出攪拌轉速。
一般情況下，塑料擠出機生產產品模溫過低時容易產生應力，應適當提高溫度。但當注射速度較高時，即使模溫低一些，也可減低應力的產生。注射和保壓時間過長也會產生應力，將其適當縮短或進行Th次保壓切換效果較好。非結晶性樹脂，如AS樹脂、ABS樹脂、PMMA樹脂等較結晶性樹脂如聚乙烯、聚甲醛等容易產生殘余應力，應予以注意。脫模推出時，由于脫模斜度小、模具型膠及凸模粗糙，使推出力過大，產生應力，有時甚至在推出桿周圍產生白化或破裂現(xiàn)象。
一般來說在正常的使用條件下制冷量下降都是因為通風散熱效果太差或環(huán)境溫度太高引起的。使用低溫冷卻液循環(huán)泵發(fā)現(xiàn)噪音比以前大很多前面提到過低溫冷卻液循環(huán)泵的日常維護工作，這個問題也與之有關。大家都知道，水里面有很少部分的雜質，就是蒸餾水在加到水箱后也不可能完全保證一點雜質都沒有。對于低溫冷卻液循環(huán)泵的水循環(huán)而言，一般溫度都設置在2℃，特別適應微生物的生長和繁衍。時間長了以后這些微生物就會堵塞水路的過濾器造成回水不暢，水泵就會有較大的噪音。
