PV7-17/10-20RE01MC0-10PV7-17/10-20RE01MC0-10 齒輪泵的結(jié)構(gòu)：PV7泵是變量葉片泵，主要由泵體、轉(zhuǎn)子、葉片、定子環(huán)、壓力控制器和調(diào)節(jié)螺釘組成。圓形的定子環(huán)在其小控制活塞和大控制活塞之間。此環(huán)的另一個(gè)接觸點(diǎn)是上面的調(diào)節(jié)螺釘。轉(zhuǎn)子在定了環(huán)內(nèi)轉(zhuǎn)動(dòng)。轉(zhuǎn)子槽內(nèi)的葉片用離心力壓在定子環(huán)上。
PV7-17/10-20RE01MC0-10PV7-17/10-20RE01MC0-10 齒輪泵的調(diào)節(jié)：小控制活塞的后面通過油道和系統(tǒng)相連，當(dāng)系統(tǒng)壓力建立起來后，此面承受系統(tǒng)壓力。當(dāng)泵排油時(shí)，大控制活塞的后面通過控制閥心和系統(tǒng)壓力相連。控制活塞的大端面由彈簧將定子環(huán)偏壓到偏心位置。此時(shí)，泵排出的液體壓力低于由壓力控制器設(shè)定的零排量壓力?？刂崎y心由彈簧控制在一定的位置。
PV7-17/10-20RE01MC0-10先導(dǎo)控制的變量葉片泵的功能：
PV7-17/10-20RE01MC0-10 齒輪泵的使排量減少：如果液體壓力面積的力大于相對(duì)的彈簧力，則控制閥心向彈簧側(cè)移動(dòng)。此時(shí)大控制活塞后面的油腔通油箱卸荷。始終在系統(tǒng)壓力作用下的小控制活塞將定子環(huán)推向其中心位置（實(shí)際上為零位）。泵維持一定的壓力，面流量降為零，泄漏得到補(bǔ)償。因而功率損失和油液的發(fā)熱降到最低水平。qv-p曲線為垂直狀，并隨設(shè)定壓力的增高面平行移動(dòng)。
PV7-17/10-20RE01MC0-10先導(dǎo)控制的變量葉片泵的使排量增加：當(dāng)系統(tǒng)壓力降到零排量壓力之下時(shí)，彈簧力推動(dòng)控制閥心回到其原始位置。大控制活塞承受到系統(tǒng)壓力，并推動(dòng)定子環(huán)移向偏心位置。泵處于排油狀態(tài)。
