葉片泵
雙作泵工作原理:它由定子、轉(zhuǎn)子、葉片和配油盤等組成。定子內(nèi)壁近似橢圓形。葉片安裝在轉(zhuǎn)子徑向槽內(nèi)并可沿槽滑動,轉(zhuǎn)子與定子同心安裝。當轉(zhuǎn)子轉(zhuǎn)動時,葉片在離心力的作用下壓向定子內(nèi)表面,并隨定子內(nèi)表面曲線的變化而被迫在轉(zhuǎn)子槽內(nèi)往復滑動,相鄰兩葉片間的密封工作腔就發(fā)生加大和縮小的變化。葉片由小半徑圓弧向大半徑圓弧處滑移時,密封工作腔隨之逐漸加大形成局部真空,于是油箱中油液通過配油盤上吸油腔吸入;反之將油壓出。轉(zhuǎn)子每轉(zhuǎn)一-周 ,葉片在槽內(nèi)往復滑移2次,完成2次吸油和2次壓油,并且油壓所產(chǎn)生的徑向力是平衡的,故稱雙作用式,也稱平衡式。
性能特點
葉片泵壓力脈動小,因磨損而產(chǎn)生的工作壓力下降車小運轉(zhuǎn)平穩(wěn)、噪音較小,結(jié)構(gòu)緊湊,起動轉(zhuǎn)矩小。但吸人條件較差,運動部件的工作可靠性較低。
1.流量較均勻,運轉(zhuǎn)平穩(wěn),噪聲較低。
2.雙作用葉片泵轉(zhuǎn)子所受徑向力是平衡的,軸承壽命長;它的內(nèi)部密封性也較好,容積效率較高;因此,一般額定排出壓力較高,可達7MPa左右。
3.結(jié)構(gòu)緊湊,尺寸較小而流量較大。
4.對工作條件要求較嚴。葉片抗沖擊較差,較容易卡住,對油液的清潔程度和粘度都比較敏感。端面間隙或葉槽間隙不合適都會影響正常工作。轉(zhuǎn)速一-般在500~2000r /道范圍內(nèi),太低則葉片可能因離心力不夠而不能壓緊在定了表面,而太高則吸人時會產(chǎn)生“氣穴現(xiàn)象”;
5.結(jié)構(gòu)較復雜,零件制造精度要求較高。
