동일한进出口压力的情况下,신氢压缩机采用二级压缩和三级压缩有什么区别,另外对于电机是选用增安型还是隔爆型,新氢压缩机出口压力为多少?

三级压缩后的压力应该越大吧。

몇 단계의 압축이 적합한지 주로는 압축비의 크기에 따라 결정됩니다.입口压力没有提到,因此无法知道你的压缩比。如果你的进口压力能达到4.1MPa以上,采用两级压缩没问题,每级的压缩比可以控制在1以内。如果进口压力低于3.1MPa,建议你采用三级压缩,压缩比同样在

这种说法的理论依据,我不知道是什么。我建议选增安型是基于安全和经济性的考虑。我见过的新氢压缩机主电机都是选用的增安型的,就是带上水冷的那种。

我有2台NEV压缩机,来氢0.94mpa,排气8.0+,两级压缩,极限工况,排气温度稳定在150度,这样基本上是极限了,压缩比比这个大的话,比如我的另2台压缩机来氢0.94,排气19+,采用三级压缩。但是我们从来没有长期开到过190公斤,因为很伤活塞环,基本两周一套三级活塞环,后来工艺调整到150公斤,活塞环半年换一次就好了。

设备选型非常严肃,不能拍脑门,需要查阅相应国标,按照设计院给出的适用标准选,基本上都是dⅡCT4的标准其中T4是温度要求,根据现场环境及电气设备过流时表面温度来确定。
