Rexroth力士樂液壓單元A10VO28DR/31R-PSC62K01電液比例溢流調速閥



PT運行中為什么二次不允許短路？答：PT正常運行時，由于二次負載是一些儀表和繼電器的電壓線圈阻抗大，基本上相當于變壓器的空載狀態，互感器本身通過的電流很小，它的大小決定于二次負載阻抗的大小，由于PT本身阻抗小，容量又不大，當互感器二次發生短路，二次電流很大，二次熔斷影響到儀表的正確指示和保護的正常工作，當容量選擇不當，二次發生短路不能熔斷時，則PT極易被燒壞。CT運行中二次為什么不允許開路？答：CT經常用于大電流條件下，同時由于CT二次回路所串聯的儀表和繼電裝置等電流線圈阻抗很小，基本上呈短路狀態，所以CT正常運行時，二次電壓很低，如果CT二次回路斷線，則CT鐵芯嚴重飽和磁通密度高達15高斯以上，由于二次線圈的匝數比一次線圈的匝數多很多倍，于是在二次線圈的兩端感應出比原來大很多倍的高電壓，這種高電壓對二次回路中所有的電氣設備以及工作人員的安全將造成很大危險，同時由于CT二次線圈開路后將使鐵芯磁通飽和造成過熱而有可能燒毀，再者鐵芯中產生剩磁會增大互感器誤差，所以CT二次不準開路。
一般篩孔尺寸為1.2mm比較合適。在預混料及魚蝦餌料生產的微粉碎過程中，由于物料粉碎粒度往往要求全部通過6-8目標準篩(.42-.18mm)，如采用機械篩分，由于粒徑過小，物料凝聚粘結，顆粒過篩困難，將造成篩分效率下降，回流粉碎量增加，從而使粉碎產量下降，粉碎能耗增加。氣流分級可以解決這一矛盾。氣流分級是一種廣義的篩分技術，它通過調節氣流工藝參數來控制物料回流或進入下一道工序的粒度，氣流的風量、風速和風壓隨物料品種及其粒度控制范圍而變化。
特殊的振動方式實現了理想的PLUGFLOW流化形式，物料移動速度相當均勻，先進來的物料先出去（firstin，firstout），不會有產品停留時間不一致而導致的受熱不均的現象，產品處理完后溫度和濕度相當均勻。、由于振動方式的特殊，對物料產生相當大的拋鄭作用力，使物料的流化非常容易，物料流化所需的風量、風壓更低，節省了能耗。、WLG系列往復式流化床采用特殊的振動結構，床子在工作時是搖動（shak，而不是傳統的振動（vibrat，噪音很低，遠低于傳統床子的振動電機的噪音。
液體性質，包括液體介質名稱，物理性質，化學性質和其它性質，物理性質有溫度c密度d，粘度u，介質中固體顆粒直徑和氣體的含量等，這涉及到系統的壓力，所需動力計算和合適泵的類型：化學性質，主要指液體介質的化學腐蝕性和毒性，是選用齒輪油泵材料和選用那一種軸封型式的重要依據。第流量是選配齒輪油泵的重要性能數據之一，它直接關系到整個裝置的的生產能力和輸送能力。選擺線齒輪泵時，以大流量為依據，兼顧正常流量，在沒有大流量時，通常可取正常流量的1.1倍作為大流量。
