葉片泵有流量均勻、運(yùn)轉(zhuǎn)平穩(wěn)、噪聲小、壽命長(zhǎng),輪廓尺寸較小、結(jié)構(gòu)較緊湊等優(yōu)點(diǎn),但也存在著自吸能力差、調(diào)速范圍小、轉(zhuǎn)速較低、葉片容易咬死、工作可靠性較差、結(jié)構(gòu)較復(fù)雜、對(duì)油液污染較敏感等缺點(diǎn)。因此在工作環(huán)境較污穢、速度范圍變化較大的機(jī)械上應(yīng)用相對(duì)較少。在工作可靠性要求很高的地方,如飛機(jī)上,也很少應(yīng)用。葉片泵在中,低壓液壓系統(tǒng)尤其在機(jī)床行業(yè)中應(yīng)用zui多。其中單作用式葉片泵常做變量泵使用,其額定壓力較低(),常用于組合機(jī)床,壓力機(jī)械等;雙作用式葉片泵只能做定量泵使用,其額定壓力可達(dá)14MPa~21MPa,在各類機(jī)床(尤其是精密機(jī)床)設(shè)備中,如注塑機(jī)、運(yùn)輸裝卸機(jī)械及工程機(jī)械等中壓系統(tǒng)中得到廣泛應(yīng)用。葉片液壓馬達(dá)zui大的優(yōu)點(diǎn)是體積小、慣性小,動(dòng)作靈敏,允許換向頻率很高、甚至可在幾毫秒內(nèi)換向。但其zui大的弱點(diǎn)是泄漏較大,機(jī)械特性較軟,不能在較低轉(zhuǎn)速下工作,調(diào)速范圍不能很大。因此適用于低轉(zhuǎn)矩,高轉(zhuǎn)速及對(duì)慣性要求較小,對(duì)機(jī)械特性要求不嚴(yán)的場(chǎng)合。由于變量葉片液壓馬達(dá)結(jié)構(gòu)較復(fù)雜,相對(duì)運(yùn)動(dòng)部件多、泄漏較大,容積效率低,機(jī)械特性軟及調(diào)節(jié)不便等原因,葉片液壓馬達(dá)一般都制成定量式的,即一般葉片液壓馬達(dá)都是雙作用式的定量液壓馬達(dá)。
