如何改变压缩机的性能曲线? 性能曲线基本不会变吧,厂家根据你的压缩介质给定的,一般不会中途更换吧,新氢机压缩的一直是新氢,循氢一直压缩的是循氢~~~~查看更多

关于德士古气化炉的开车吹扫问题? 气化炉在停车换喷嘴前要用高压氮气吹除喷嘴处的煤浆管道和氧气管道,目的是防止煤浆沉积堵塞管道,引起开车后煤浆流量不稳或无流量,吹氧气管道,是为防止管道内进杂物,开车时引起氧气管道着火。个人理解,欠妥。查看更多
水浴式汽化器在使用中应注意什么? 水浴式汽化器在使用中,其水温是不可以太高的,保持在60度左右,因其管网及压力容器都有设计温度,就是防止温度超高而损坏设备或造成管网法兰热胀冷缩而出现漏气现象;再就是注意,防止水浴式汽化器水温过低,出口管路出现结霜或出现管道冻裂现象而影响正常运行;查看更多
计算泵的安装高度时,气蚀余量是以NPSHa带入,还是以NPS ...? 我理解应该是npshr,它是必需气蚀余量,是泵设备制造时定下来的,不能变,而npsha是有效气蚀余量,是个计算 ... 除了第一句话是错误的,后面的解释完全正确,建议再复核一下,安装高度应该用有效气蚀余量, 只有一种情况可以用npshr,也就是,题目没有要求安全裕量,即npsha=npshr。查看更多

好的英语是“读”出来的? 改变人生的100个方法(4) 31. open the present. **** practice being awake in the present moment. make the most awareness of this moment. don't live the past unless you like guilt. don't live in the future unless you like fear. just stay focused on today. watch what happens to your motivation. 32. serve and grow rich. you can motivate yourself by increasing the flow of money into your life. most people are even embarrassed to think this way. they don't want to think and grow rich because they'll be though as being greedy. they believe to make money, you have to take it away from someone else. or they don't want to come across as being obsessed with money. you know who are the people that are really obsessed with money? people who think they don't have enough. they obsess of money all day long. it's in their family discussions, it's in their minds at night, it becomes a destructive part of their relationships during the day. "our first duty in life is not to be poor" - george bernard shaw. the road to not being poor always travels through your professional relationships. the more serve those relationships, the more productive you'll become and the more money you'll make. allow yourself to link your financial well being with your increase compassion for others. if i live in poverty, how much love and attention can i give my children or to my fellow humans. how much help can i give to others if i'm always worrying about being in debt. 33. imitate 'columbo' in your professional life, always be curious. when you meet with someone think of yourself as a detective. ask questions. by asking questions in your relationships, your already creating the relationship. your already self motivated. your not waiting for the other person to make it happen. 34. give away some power. **** motivate yourself by giving someone else the ideas for self motivation. you can have any experience you want in life, simply by giving away that experience to someone else. it's called "instant karma." if you want to be motivated, shift your inspiration to someone else. point out their strengths. offer encouragement and support. watch what it does for you. 35. talk to yourself. * **** don't be nervous talking to yourself. we associate it with 'insanity'. but plato said, "thinking was the soul talking to itself." there is no one better to talk to then yourself when you really want to get things worked out. no other person has enough information about your problems. no one knows your skills and capabilities better. we get our creative thinking going each morning by asking ourselves 2 questions. 1. what's good in my life? 2. what is there still to be done? because thought always perceive action. talking to yourself is a proven way to get motivated. 36. schedule your comebacks. progress toward your goals is never going to be a straight line, it's always going to be a wavy line. you'll go up and come down a little. two steps forward and one step back. now most people will get discouraged when they take the two steps back, they think they're failing. but they really hasn't. they really in sync with the natural rhythm of progress. now once you understand this rhythm, you can look ahead on your calendar to refresh, renew, and recover. schedule your comeback while you're still on top. schedule a block of time to get away. even to get away from what you love. because coming back is going to be that much more exciting when you've been renewed. 37. live you're true life. * "when you say you fear death, you're really saying you've not lived you're true life." this fear cloaks the world in true suffering. how do you know what you're true life is? how do you know how to live it? first, find out what makes you happy and start doing that. i.e. if writing makes you happy, start writing. don't just wait until something is offered to you. be proactive about your happiness. there is no goal better than this one. to know as you lay in you're death bed that you've lived you're true life. you did what it was that made you happy. 38. get up on the right side of the bed. get up on the right side of you're brain. dreams, and energy, and creative insight comes from the right side of the brain. linear, logical, short term, and short sighted thinking comes from the left side of the brain. the best explanation of how whole brain thinking surpasses just one sided thinking is in a book called, "frankenstein's castle." - wilson. we have more control in drawing vital energy and creative ideas from right brain then we ever realized. and what stimulates the right brain the most is a high sense of purpose. if you had to carry a bag of sand around town, you're left brain would say it was boring. but if you had to carry your daughter that weighed the same as the bag of sand, then you would carry her with more energy. that energy comes from the right side of the brain. purpose gives you that energy. self motivation increases when the left brain gets good at telling the right brain what to do. 39. use your magic machine. * most people wait for an external crisis to finally kick in their whole brain thinking. but the leads to a life of reaction other than creation. the 3 best ways to activate whole brain thinking are through 1. goal setting. 2. joyful work. 3. revitalizing play. so rather wait for some external crisis to appear, you can create an internal challenge of your own. goals and games. goals and games motivate you more than anything else in the world. 40. get your stars out. "make sure you get your stars out." let the universe that is in you shine freely. don't try too hard to force things, just get your stars out and let them shine.查看更多
谈谈注册化工工程师专业考试? 注册的作用,个人感觉:1、为了自己将来的工作,也即前程。现在设计单位比较看重注册证,如果要凭资质需要有相应人数的注册师。2、也为了自身能力的提高,可以系统地重新学习专业知识。查看更多
