"[2]请问一下离心式压缩机,启动前入口阀门的状态是全开 还是 半开 好。为什么?\n"["

"[3] 西门子的离心机一般IG从开度度开机前是 半开-半关 之间:)\\n"["
Reply #32017-02-07
"[4] 汽轮机驱动的 半开 就可以,电机驱动的开度在 半开-半关 都可以!\n"["

"[5] 估计你说的是导叶吧,这个是工艺要求的呢,正常的离心机进出口是两位阀,只有工艺需要调节气量的时候才设置导叶,具体工艺而定吧:) \n"["

"[6] 遇到的两台压缩机启动时入口阀都是 半开 左右的开度,防喘振阀全开\n"["

"[7] 我们这一般用电机拖动的进口阀开度在 半开%,目的是电机启动电流不会超负荷。\ \n"["

"[8] 个人感觉无非是防止启动电流过大 所以只要关小即可吧 或许也应该根据不同的工况确定\n"["

"[9] 启动时入口阀先开 半开-半关%,防止电机超负荷\n"["

"[1] 根据工况吧 我们这是全开的\n"["

"[1] 在启动前开 半开-半关%,为防止电超负荷。正常运转时根据情况开 不一定。\ \n"["

"[1] 电机启动 半开-半关%,汽轮机启动全开。\ \n"["
Reply #122017-02-08
"[13] 这还是要根据工艺要求来决定的!只要不超负荷 不不超压就可以啊!\n"["

"[14] 汽轮机驱动的 入口阀全开会造成出口压力瞬间升高。很危险。不知道你们的工艺是怎么样的 我们启动前是 半开%,也就是基本全关。等到转速正常后才开启入口导叶建立压力(\n
