我們對關(guān)鍵部件，如分配板，葉輪和泵軸進(jìn)、行了系統(tǒng)優(yōu)化設(shè)計(jì)，簡化了結(jié)構(gòu)，提高了性能，實(shí)現(xiàn)節(jié)能。采用焊接葉輪，葉片一次沖壓、成型型線合理：輪轂全部加工，從根本上解決了動(dòng)平衡問題。葉輪與泵軸采用熱裝過盈配合，性能可靠，運(yùn)轉(zhuǎn)平穩(wěn)。葉輪焊接后，整體進(jìn)行良好的熱處理，葉片具有良好的韌性，使葉片的抗沖擊，抗折彎能力得以根本保證，能適應(yīng)載荷沖擊波的惡劣工況。<img src='http:///pic/125176/2/20160310160508_6138_zs_sy.jpg' /> <br /><p>該機(jī)組可配套提供JZ系列油擴(kuò)散噴射泵真空機(jī)組（又稱油增壓泵機(jī)組）。該機(jī)組抽氣能力大、粗抽時(shí)間短、設(shè)備維護(hù)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(jī)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。現(xiàn)廣泛地被太陽能制品企業(yè)所應(yīng)用。</p><p>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.</p><img src='http:///pic/125176/2/20160405145320_6083_zs_sy.jpg' /><img src='http:///pic/125176/1/20160307133712_5089_zs_sy.jpg' /><br /><p>它除了具有一般羅茨真空泵機(jī)組的一些特點(diǎn)外，由于采用水環(huán)式真空泵作前級泵，因此，它特別適用于抽除含較多蒸氣及有一定腐蝕性氣體的工業(yè)流程中。例如：For example:制藥業(yè)的真空蒸餾、真空蒸發(fā)、脫水結(jié)晶；輕紡工業(yè)的滌綸切片干燥；食品工業(yè)的冷凍、干燥等工藝均可采用。</p><p>Besides having some features of general Roots vacuum pump, this unit treats two-stage water-ring vacuum pump as prepump, so it is specially suitable for industrial-process with a large quantity of vapor and some corrosive gases.The process such as vacuum distillation, vacuum evaporation, dehydration and crystallization in pharmacy, polyester chips drying in textile industry, freezing and drying in food industry could be adopted.</p><img src='http:///pic/125176/2/20160405145320_6083_zs_sy.jpg' />
