一、調(diào)節(jié)可以是連續(xù),、無級的,,也可以在液壓系統(tǒng)工作過程中-車地進(jìn)行。
二,、通過改變排量實現(xiàn)調(diào)速成為容積調(diào)速,,這種方法和另一種所謂的節(jié)-速相比,功率損失小,,避免了系統(tǒng)-,,很適合大功率系統(tǒng)。
三,、容積式泵剛性的壓力-流量特性對液壓傳動雖然是很-的,,但是往往和流量調(diào)節(jié)的要求有矛盾,因而有-將容積式泵的原始壓力-流量特性加以改造,。這就是變量調(diào)節(jié)機構(gòu)的任務(wù),。
四、威格士葉片泵中推動變量機構(gòu)動作的動力源及控制方式是多種多樣的,,但大體上可以分層兩類:

2、在盡量縮短威格士葉片泵管路長度的同時可減少管路壓力損失和振動等,,要采取避免因溫升產(chǎn)生的管路熱伸長而拉斷,、拉裂管路,,并注意接頭部位的,。
3、和軟管一樣,,在靠近接頭的部位需要有一段直線部分,。
4、彎曲長度要適量,,不能斜交,。

5、 防止威格士葉片泵系統(tǒng)液壓沖擊帶來的泄漏,。產(chǎn)生液壓沖擊時,,會導(dǎo)致接頭螺母松動而產(chǎn)生漏油。
6,、此時,,一方面應(yīng)重新擰緊接頭螺母,另一方面要找出產(chǎn)生液壓沖擊的原因并設(shè)法予以防止,。例如設(shè)置蓄能器等吸振,,采用緩沖閥等緩沖組件消振等。
7,、威格士葉片泵負(fù)壓產(chǎn)生的泄漏,。對瞬時流速大于10m/s的管路,均可能產(chǎn)生瞬間負(fù)壓(真空)現(xiàn)象,,如果接頭沒有采用防止負(fù)壓產(chǎn)生的密封結(jié)構(gòu)形式,,
負(fù)壓產(chǎn)生時會吸走威格士葉片泵內(nèi)的o形密封圈,壓力上來時因無o形密封圈而產(chǎn)生泄漏。
