該機組可配套提供JZ系列油擴散噴射泵真空機組(又稱油增壓泵機組)。該機組抽氣能力大、粗抽時間短、設(shè)備維護簡單、操作方便,是真空應(yīng)用設(shè)備的理想配套設(shè)備。但該機組不適于排除對金屬有腐蝕作用及對泵油產(chǎn)生化學(xué)反應(yīng)的氣體?,F(xiàn)廣泛地被太陽能制品企業(yè)所應(yīng)用。
This unit comes with JK serial oil diffusion jet vacuum pump unit (also called oil booster unit).It has good capacity of gas extracting, with short rough extracting, easy to maintain and operating. It is ideal corollary equipment for vacuum application equipment.But this unit is not suitable for the gases which exclude corrosion towards metals and chemical reaction towards pump oil.Now it is widely applied by solar product enterprises.

泵總體結(jié)構(gòu)型式
真空泵的泵體的布置結(jié)構(gòu)決定了泵的總體結(jié)構(gòu)。
立式結(jié)構(gòu)的進、排氣口水平設(shè)置,裝配和連接管路都比較方便。但泵的重心較高,在高速運轉(zhuǎn)時穩(wěn)定性差,故這種型式多用于小泵。


根據(jù)被抽真空系統(tǒng)的大小及氣體狀態(tài),真空機組各泵之間的名義抽速之比一般在4∶1至10∶1之間,前者適用于較大真空系統(tǒng)及長時間在較低入口壓力或極限真空情況下工作。本系列羅茨真空機組為了防止前級旋片真空泵停機返油,在前級管道上裝有電磁放氣閥,其動作與前級旋片真空泵的電機聯(lián)動。
