GP和GP*AN系列派克齒輪泵@PARKER東莞*派克液壓閥

Parker派克GP和GP*AN系列齒輪泵是用于開式回路的齒輪泵，壓鑄鋁殼體，流體靜壓間隙補償，滑動軸承，單泵或多聯(lián)泵。此系列齒輪泵的特點有：高精加工的齒輪副。特殊的生產(chǎn)技術使彼此間的密封間隙zui小。用于靜壓間隙補償?shù)亩嗣鎵毫^(qū)域帶有密封件。通過選擇*的齒數(shù)使得泵的流量脈動小并且噪音低。高壓采用用于高載荷的滑動軸承采用壓鑄鋁的泵體使得泵的重量輕。排量為1.6-87.6ml/rev，額定壓力至230bar，zui高壓力可達270bar。
Parker派克齒輪泵是依靠泵缸與嚙合齒輪間所形成的工作容積變化和移動來輸送液體或使之增壓的回轉(zhuǎn)泵。由兩個齒輪、泵體與前后蓋組成兩個封閉空間，當齒輪轉(zhuǎn)動時，齒輪脫開側(cè)的空間的體積從小變大，形成真空，將液體吸入，齒輪嚙合側(cè)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*取決于泵出處阻力的大小。
