某离心压缩机试运转时出现振动故障,经测试,判断故障是转子与密封碰磨而致。为验证故障原因,将轮盖密封以及隔板密封取出,之后机组的运行效果以及运转状况均较为良好,说明故障的原因诊断正确。在对机组的密封间隙进行相应调整之后,转子的故障得到消除,机组能够正常运行,运转状态及运行效果均良好。

Heisenberg introduced the concept of isospin to describe different charge states of the nucleon,where the proton(p)and neutron(n)are treated as an isospin T=1/2
In the present work,new fundamental properties of twisted electron beams are obtained.We demonstrate for the first time that a twisted spin-1/2 particle can pos
Description of Weakly Bound and Resonant Nuclei with the Gamow Shell Model using Effective and Reali
We investigate the theoretical description of nuclei at drip-lines.For this,the Gamow shell model has been developed to study the properties of weakly bound and
Basis light-front quantization(BLFQ)as a nonperturbative approach has been successfully applied to QED and QCD systems[1–13].Treating the proton as a system of
The nucleon spatial density distribution is of critical importance for atomic nucleus structure.The nuclei with central density depletions,usually called bubble
Approaching the Neutron-rich Heavy and Superheavy Nuclei by Multinucleon Transfer Reactions with Rad
Within the dinuclear system(DNS)model,we investigate the dynamical mechanism of multinucleon transfer(MNT)reactions,in which the sequential nucleon transfer is
