PVD系列單泵主要特點(diǎn)：
1.設(shè)計(jì)合理、加工精密的圓弧葉片，降低了葉片對(duì)定子內(nèi)曲線的壓應(yīng)力，提高了定子和葉片的使用壽命；
2.定子采用先進(jìn)的高次方無沖擊過渡曲線，使葉片具有良好的運(yùn)動(dòng)和受力狀態(tài)，保證了葉片與定子間的良好接觸，并使得流量損失、壓力和流量脈動(dòng)為*小，噪聲更低，壽命更長(zhǎng)；
3.側(cè)板采用液壓平衡，可獲得更好的容積效率；
4.關(guān)鍵零件選用上等的材料和先進(jìn)的熱處理工藝，油泵整體可靠性進(jìn)一步提高；
5采用組合式結(jié)構(gòu)，泵芯更換可在幾分鐘內(nèi)完成，互換性好，維修方便。
