600MW抗燃油系统冲洗步骤及方案

前言

因为抗燃油的压力高、液压运动部件的间隙小、伺服阀最小间隙为5~10um,所以必须保证油质颗粒度达到规定的MOOG2或NAS5级才能进行下步阶段的调试工作。

EH系统的油冲洗

系统油冲洗后,必须使油质颗粒度达到规定的MOOG2或NAS5级后,才能将抗燃油引入系统元件。

1)系统上油前的准备:

a 连接各部套的电气线路。 b 按下表将各开关置于正确位置 开关名称 位置 1#EHC泵/2#EHC泵 1#循环泵 2#循环泵 加热器

关 关 关 关

若设有远控开关,应将其置于“停止”位

c 检查主泵出口滤油器差压发讯器有无变红,若有,需查明原因。

Mayblum would scoff. I’m on the 87th floor of the World Trade Center. That’s power. The drawstrings on his window shades would appear to sway slightly, but it was an illusion. Although they were 1,040 feet in the sky, The WTC was quite steady.

We should always bear in mind that if we are ignorant of our health for promotion,disease will gradually approach us with the help of tiredness.

我们应该牢记:如果我们为了晋升而忽略了我们的健康,疾病便会借助疲劳乘虚而入。 I looked for the history book because I wanted to find out when America was founded,and at last I found the dusty book in a dim room.

EH油系统讲解

EH油系统

EH油系统按其功能分为三大部分:

EH供油系统,执行机构部分,危急遮断部分。 一、 EH供油系统

EH供油系统的功能是提供高压抗燃油,并由它驱动各执行机构,同时保持液压油的正常理化特性和运行特性。这种抗燃油是一种三芳基磷酸脂,它具有良好的抗燃性和液体的稳定性。

EH供油系统主要由EH油箱、EH油泵、出入口门、滤网、控制块、溢流阀、蓄能器、EH供回油管、冷油器以及一套自循环滤油系统和自循环冷却系统组成。

EH油从油箱经油泵入口门、入口滤网、EH油泵(高压变量柱塞泵)、EH油控制块(包括出口滤网、逆止阀、出口门、溢流阀)后,经高压蓄能器和高压供油母管HP送至各执行机构和危急遮断系统,系统执行机构的回油经有压回油母管DP、回油滤网、回油冷却器回到油箱;危急遮断系统的回油经无压回油母管DV1、DV2回油箱。机组正常运行时无压回油母管中的回油为AST危急遮断控制块内危急遮断油经两个节流孔后的排油,在两个节流孔之间安装有两个压力开关,用来监视、试验AST电磁阀工作、动作情况。 1、设备介绍

1) 油箱:油箱板上装有液位开关、磁性滤油器、空气滤清器、控制块,另外油箱底部外侧装有电加热器,间接对EH油加热。

2) EH油泵:出口压力整定在

We are a team.

We struggle together. 我们一起奋斗。 We triumph together.我们一起取得胜利。

If one of us fails, 如果我们中有一个人失败了, we all fail.那我们大家都会失败。

If one of us breaks a rule,如果我们中有一个人违反了规则, We all should be punished.那我们大家都应受到惩罚。 If one of us lags behind, 如果我们中有一个人落后了, We all should help him.我们大家都要帮助他。

If one of us succeeds,如果我们中有一个人成功了, We all should celebrate.我们大家就会一起庆祝。 We are a great team.我们是一支伟大的团队。 We care about each other.我们互相关心。 We encourage each other.我们互相鼓励。 We push each other.我们相互推动。 We love each other.我们彼此关爱。

汽机EH油系统祥解

氢电导对水样中离子有放大功能,放大倍数3.1-3.3,能更好的反映水质变化。

单就燃机来说,应该是西门子最好,其次是三菱,GE很垃圾;就国内配套厂比较,三菱配合的东方电气最好,至于哈尔滨和上气,都不咋的!另有北重在和阿尔斯通合作,不过没有燃机。

至于联合循环的性能方面,西门子最优,发电机中置,启动灵活快速;三菱和GE都是采用发电机后置、汽轮机具中,启动快速性和灵活性守限制,且因轴系过长、扭矩大,振动相对比较高;

单纯燃机振动方面,是GE的硬伤,从9E开始一直是振动高、燃烧不稳定,火焰管联焰致使联焰管容易烧坏,燃烧模式切换容易熄火跳机;西门子的燃烧系统设置应该是最优的,环形燃烧室,24个燃烧器独立点火,成功率几乎百分之百,没有联焰管之类容易故障;三菱了解不多,但三菱也是靠火焰管传递火焰,不会好的到哪里去,个人看法,仅供参考。

三菱:

M701DA燃气蒸汽联合循环机组在性能保证工况下出力为210.9MW(纯凝),联合循环机组效率49.99%(纯凝)。M701DA燃机的压气机有19级叶轮,压比为14,压气机叶片都有防空气腐蚀的涂层,前7级涂层与后12级涂层材料不同,依据出力下降决定水洗,用冷除盐水直接进行离线水洗。压气机转子为传统的红套结构,而非

增加,氧化性能增快,氧化会使抗燃油酸度增加,颜色变深;油温过高会引起EH油及调速部件局部碳化,影响油质和调节。 EH油温过高原因:

1.EH油内有杂质,油质恶化,杂质吸附在管壁上引起管壁散热慢 2.EH溢流阀经常性动作,是EH油泵做功后将加热EH油回到油箱 3.EH油循环泵处理不足冷却油量少
