PEP-II泵的齒輪與軸共為一體,采用通體淬硬工藝,可獲得更長的工作壽命。"D"型軸承結(jié)合了強(qiáng)制潤滑機(jī)理,使聚合物經(jīng)軸承表面,并返回到泵的進(jìn)口側(cè),以確保旋轉(zhuǎn)軸的有效潤滑。這一特性減少了聚合物滯留并降解的可能性。精密加工的泵體可使"D"型軸承與齒輪軸精確配合,確保齒輪軸不偏心,以防齒輪磨損。Parkool密封結(jié)構(gòu)與聚四氟唇型密封共同構(gòu)成水冷密封。這種密封實(shí)際上并不接觸軸的表面,它的密封原理是將聚合物冷卻到半熔融狀態(tài)而形成自密封。也可以采用Rheoseal密封,它在軸封內(nèi)表上加工有反向螺旋槽,可使聚合物被反壓回到進(jìn)口。為便于安裝,制造商設(shè)計(jì)了一個(gè)環(huán)形螺栓安裝面,以使與其它設(shè)備的法蘭安裝相配合,這使得筒形法蘭的制造更容易。PEP-II齒輪泵帶有與泵的規(guī)格相匹配的加熱元件,可供用戶選配,這可保證快速加溫和熱量控制。與泵體內(nèi)加熱方式不同,這些元件的損壞只限于一個(gè)板子上,與整個(gè)泵無關(guān)。。
為了減少隔擋處的磨損,就需要設(shè)置幾個(gè)盲孔,該盲孔在與一個(gè)壓油柱塞缸相通時(shí),充滿壓力油液,在緊接著切斷時(shí),孔內(nèi)的油液這時(shí)就起著類似彈簧的作用,從而使配油盤接觸表面卸荷和改善潤滑條件。盲孔的尺寸設(shè)計(jì)通常取為:直徑1.5~2.0毫米,深度6~8毫米。。

另外,人們又想到早期的配油機(jī)構(gòu),這一循環(huán)是上升到靜平壓平衡的基礎(chǔ)上,滾動(dòng)體只承受很小一部分載荷。隨著靜壓支承技術(shù)的進(jìn)展,進(jìn)而發(fā)展了一種靜壓支承配油盤,在配油盤配油窗口的外周(或內(nèi)周)專門開設(shè)了一組靜壓支承,在缸體與配有盤平面之間形成一層穩(wěn)定的油膜。。
