威格士VICKERS齒輪泵運(yùn)行維護(hù)1,、起動(dòng)：
（1）啟動(dòng)前檢查全部管路法蘭，接頭的密封性,。
（2）盤動(dòng)聯(lián)軸器,，無(wú)摩擦及碰撞聲音。
（3）啟動(dòng)應(yīng)向泵內(nèi)注入輸送液體,。
（4）啟動(dòng)前應(yīng)全開(kāi)吸入和排出管路中的閥門,，嚴(yán)禁閉閥啟動(dòng)。
（5）驗(yàn)證電機(jī)轉(zhuǎn)動(dòng)方向后,，啟動(dòng)電機(jī)。
2,、停車：
（1）關(guān)閉電動(dòng)機(jī),。
（2）關(guān)閉泵的進(jìn)、出口閥門,。
威格士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(zhǎng)的工作壽命,。“D”型軸承結(jié)合了強(qiáng)制潤(rùn)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(rùn)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。
威格士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(wú)關(guān)。
威格士齒輪泵由一個(gè)獨(dú)立的電機(jī)驅(qū)動(dòng),，可有效地阻斷上游的壓力脈動(dòng)及流量波動(dòng),。在齒輪泵出口處的壓力脈動(dòng)可以控制在1%以內(nèi)。在擠出生產(chǎn)線上采用一臺(tái)齒輪泵,，可以提高流量輸出速度,，減少物料在擠出機(jī)內(nèi)的剪切及駐留時(shí)間，降低擠塑溫度及壓力脈動(dòng)以提高生產(chǎn)率及產(chǎn)品質(zhì)量
