罗茨真空泵机组 |
 罗茨水环真空机组是以罗茨泵为主泵，以水环泵为前级泵串联而成的。罗茨水环真空机组选用水环泵作为前级泵比其它真空泵更为有利，它克服了单台水环泵使用时极限压力差（机组的极限压力比水环泵有很大的提高），在一定压力下抽气速率低的缺点，同时保留了罗茨泵能迅速工作，有较大抽气速率的优点。尤其能够适应抽除大量的可凝性蒸汽，特别是当气镇油封机械真空泵排除可凝性蒸汽能力不够，或使用的溶剂能使泵油恶化而影响性能，或者是真空系统不允许油污染的时候更为明显。当配有防爆电机及电器时并遵守相应的无危险的规则下,还可抽除易燃易爆的气体。因此罗茨泵-水环泵机组广泛地用于化工行业中的真空蒸馏、真空蒸发、脱水结晶；食品行业中的冷冻干燥；医药工业的真空干燥；轻纺工业的涤纶切片；高空模拟试验等的抽真空系统中。Roots water ring vacuum unit is composed of roots pump and water ring pump in series. Roots water ring vacuum unit is chosen as the backing pump water ring pump more advantageous than other vacuum pump, it overcomes the single water ring pump when using the limit pressure difference (extreme pressure of the unit has greatly improved than water ring pump), a disadvantage of low extraction rate under certain pressure, while retaining the roots pump can work quickly, has the advantages of larger extraction rate. In particular, it can be adapted to remove a large number of condensable steam, especially when the gas sealing mechanical vacuum pump is not enough to remove condensable steam, or the use of solvents can make the pump oil deterioration and affect the performance, or the vacuum system does not allow oil pollution when more obvious. When equipped with explosion-proof motor and electrical appliances and comply with the corresponding non-dangerous rules, but also can be removed flammable and explosive gas. Therefore, roots pump-water ring pump unit is widely used for vacuum distillation, vacuum evaporation and dehydration crystallization in the chemical industry. Freeze-drying in the food industry; Vacuum drying in pharmaceutical industry; Polyester chips for light industry; High altitude simulation test in the vacuum pumping system. |
