daili美國原裝威格士柱塞泵概述：

daili美國原裝威格士柱塞泵，是由電動機提供泵的動力，經(jīng)鼓型齒聯(lián)軸器帶動減速機轉(zhuǎn)動。由減速機減速帶動曲軸旋轉(zhuǎn)。通過曲柄連桿機構(gòu)，將旋轉(zhuǎn)運動轉(zhuǎn)變?yōu)槭诸^和柱塞為往復運動。當柱塞向后死點移動時，泵容積腔逐步增大，泵腔內(nèi)壓力降低，當泵腔壓力低于進口壓力時，吸入閥在進口端壓力作用下開啟，液體被吸入；當柱塞向前死點移動時，泵腔內(nèi)壓力增大，此時吸入閥關(guān)閉，排出閥打開，液體被擠出液缸，達到了吸入和排出的目的。
daili美國原裝威格士柱塞泵滑靴與斜盤的滑動磨擦是斜盤柱塞泵三對磨擦副中zui為復雜的一對。 出柱塞桿球頭與滑靴球窩的間隙，如果柱塞與滑靴間隙超差，柱塞腔中的高壓油就會從柱塞球頭與滑靴間隙中泄出，滑靴與斜盤油膜減薄，嚴重時會造成靜壓支承失效，滑靴與斜盤發(fā)生金屬接觸磨擦，滑靴燒蝕脫落，柱塞球頭劃傷斜盤。柱塞桿球頭與滑靴球窩超出公差1.5倍時，必須成組更換之
柱塞往復運動總行程L是不變的，由凸輪的升程決定。柱塞每循環(huán)的供油量大小取決于供油行程,供油行程不受凸輪軸控制是可變的。供油開始時刻不隨供油行程的變化而變化。轉(zhuǎn)動柱塞可改變供油終了時刻，從而改變供油量。柱塞泵工作時，在噴油泵凸輪軸上的凸輪與柱塞彈簧的作用下，迫使柱塞作上、下往復運動，從而完成泵油任務，泵油過程可分為以下三個階段。
