一、概况洛阳炼油厂100万吨/年全渣油催化装置设有二台 D1800-3.2/0.98型主风机组,功率5450KW。1号机组由汽轮机和离心式鼓风机组成;2号机组由汽轮机-离心式鼓风机-烟气透平机组成。二台机组均为1978年度试制产品,1984年底试运,中间闲置时间较长,二台机组在安装和试运中遇到一些问题严重影响了机组投运。本文着重叙述主要问题及其处理。二、存在的主要问题及处理1.轴承与汽封洼窝不同心汽轮机前轴承中心与汽缸前汽封洼窝不同心,1号机组达-0.38mm(轴承中心低 I. Overview Luoyang refinery 100 tons / year full residue catalytic device with two sets of D1800-3.2 / 0.98 main fan unit, power 5450KW. Unit 1 consists of steam turbine and centrifugal blower; Unit 2 consists of steam turbine - centrifugal blower - flue gas turbine. Both units were trial products in 1978, and were commissioned by the end of 1984 with a long idle time in the middle. Some problems encountered during the installation and commissioning of the two units seriously affected the commissioning of the units. This article focuses on the main issues and their handling.
