水环式真空泵广泛应用于食品、石油、化工制药、冶金工业及电子领域的真空蒸发,过滤,干燥,浓缩,蒸馏及真空结晶等工艺过程。在运行过程中,水环式真空泵转速过高会产生什么不利影响呢?

1、水环式真空泵运行中的吸气和排气通过气阀动作来实现,若转速过高,会导致气阀动作跟不上,容易产生滞后现象,致使增加容积损失,反而不利于真空度的提高,同时还会导致泵阀撞击严重,加剧水环式真空泵设备的磨损

2、水环式真空泵设备本身会震动,随着转速的提高,它的各部分的振动也将增大,会产生不利影响

3、另一种情况是因为转速高,在一定的抽气速率下行程就越短,而装气阀、缸径又不能太小,否则会引起水环式真空泵余隙容积增大,压缩线和膨胀线变短,不利于提高真空度。为保证真空,水环式真空泵应采用低转速、长行程

4、转速提高之后,平衡通道的水环式真空泵的平衡作用就会变得不明显,不能及时平衡气体,也就不能减少余隙容积带来的影响,从而影响水环式真空泵的真空度
