齒輪泵的產品介紹
齒輪泵是依托泵缸與嚙合齒輪間所構成的作業容積變化和移動來運送液體或使之增壓的回轉泵。由兩個齒輪、泵體與前后蓋組成兩個封閉空間,當齒輪轉動時,齒輪脫開側的空間的體積從小變大,構成真空,將液體吸入,齒輪嚙合側的空間的體積從大變小,而將液體擠入管路中去。吸入腔與排出腔是靠兩個齒輪的嚙合線來隔開的。齒輪泵的排出口的壓力******取決于泵出口處阻力的大小。

結構特色
(1)結構簡單,******便宜;
(2)作業要求低,應用廣泛;
(3)端蓋和齒輪的各個齒間槽組成了許多固定的密封作業腔,只能用作定量泵。
齒輪采用國際九十年代******水平的新技術--雙圓弧正弦曲線齒型圓弧。它與漸開線齒輪比較,.突出的優點是齒輪嚙合過程中齒廓面沒有相對滑動,所以齒面無磨損、作業平衡、無困液現象,噪聲低、壽命長、效率高。該泵脫節傳統規劃的捆綁,使得齒輪泵在規劃、出產和使用上進入了一個新的范疇。
泵設有差壓式安全閥作為超載維護,安全閥全回流壓力為泵額定排出壓力1.5倍。也可在答應排出壓力范圍內依據實際需要另行調整??墒谴税踩y不能作減壓閥長時間作業,減壓閥在需要時可另行安裝。
