我们对关键部件，如分配板，叶轮和泵轴进、行了系统优化设计，简化了结构，提高了性能，实现节能。采用焊接叶轮，叶片一次冲压、成型型线合理：轮毂全部加工，从根本上解决了动平衡问题。叶轮与泵轴采用热装过盈配合，性能可靠，运转平稳。叶轮焊接后，整体进行良好的热处理，叶片具有良好的韧性，使叶片的抗冲击，抗折弯能力得以根本保证，能适应载荷冲击波的恶劣工况。<img src='http:///pic/125176/2/20160310160508_6138_zs_sy.jpg' /> <br /><p>该机组可配套提供JZ系列油扩散喷射泵真空机组（又称油增压泵机组）。该机组抽气能力大、粗抽时间短、设备维护简单、操作方便，是真空应用设备的理想配套设备。但该机组不适于排除对金属有腐蚀作用及对泵油产生化学反应的气体。现广泛地被太阳能制品企业所应用。</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>它除了具有一般罗茨真空泵机组的一些特点外，由于采用水环式真空泵作前级泵，因此，它特别适用于抽除含较多蒸气及有一定腐蚀性气体的工业流程中。例如：For example:制药业的真空蒸馏、真空蒸发、脱水结晶；轻纺工业的涤纶切片干燥；食品工业的冷冻、干燥等工艺均可采用。</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' />
