Coriolis forces. These forces are always present when both translational and rotational movements are superimposed.F C = 2 · ∆m (v · ω)F C = Coriolis force ∆m = moving mass ω = rotational velocityv = radial velocity in rotating or oscillating systemThe amplitude of the Coriolis force depends on the moving mass ∆m, its velocity v in the system, and thus on the mass flow. Instead of a constant angular velocity ω, the Promass sensor uses oscillation.In the Promass F and M sensors, two parallel measuring tubes containing flowing fluid oscillate in antiphase, acting like a tuning fork. The Coriolis forces produced at the measuring tubes cause a phase shift in the tube oscillations (see illustration):•At zero flow, in other words when the fluid is at a standstill, the two tubes oscillate in phase (1).The phase difference (A-B) increases with increasing mass flow. Electrodynamic sensors register the tube oscillations at the inlet and outlet.System balance is ensured by the antiphase oscillation of the two measuring tubes. The measuring principle operates independently of temperature, pressure, viscosity, conductivity and flow profile.Density measurementThe measuring tubes are continuously excited at their resonance frequency. A change in the mass and thus the density of the oscillating system (comprising measuring tubes and fluid) results in a corresponding, automatic adjustment in the oscillation frequency. Resonance frequency is thus a function of fluid density. The microprocessor utilises this relationship to obtain a density signal.Temperature measurementThe temperature of the measuring tubes is determined in order to calculate the compensation factor due to temperature effects. This signal corresponds to the process temperature and is also available as an output.The temperature measurement cannot be used to generate data for invoicing in applications subject to legal metrology controls.Proline Promass 84F, 84M Measuring system The measuring system consists of a transmitter and a sensor. Two versions are available:•Compact version: transmitter and sensor form a single mechanical unit.•Remote version: transmitter and sensor are installed separately.4Endress+HauserProline Promass 84F, 84MEndress+Hauser 5InputMeasured variable•Mass flow (proportional to the phase difference between two sensors mounted on the measuring tube to register a phase shift in the oscillation)•Fluid density (proportional to resonance frequency of the measuring tube)•Fluid temperature (measured with temperature sensors)Measuring range in non-custody transfer modeMeasuring ranges for liquids (Promass F, M):Measuring ranges for gasesThe full scale values depend on the density of the gas.

External forces are absorbed by the construction of the instrument, for example the secondary containment.•The high oscillation frequency of the measuring tubes ensures that the correct operation of the measuring system is not influenced by pipe vibrations.•No special precautions need to be taken for fittings which create turbulence (valves, elbows, T-pieces, etc.), as long as no cavitation occurs.•For mechanical reasons and in order to protect the pipe, it is advisable to support heavy sensors.•Please refer to the verification ordinances for the installation conditions of the approval for custody transfer in question.!Note!The necessary steps for creating a measuring system and obtaining approval from the Standards Authorities must be clarified with the authority for legal metrology controls responsible.Mounting locationEntrained air or gas bubbles in the measuring tube can result in an increase in measuring errors Avoid the following locations:•Highest point of a pipeline. Risk of air accumulating.•Directly upstream of a free pipe outlet in a vertical pipeline.Mounting locationDN Promass F [% o.r./bar]Promass M [% o.r./bar]Promass M / (high pressure)[% o.r./bar]8No influence 0.0090.00615No influence 0.0080.00525No influence 0.0090.00340-0.0030.005-50-0.008No influence -80-0.009No influence−100-0.012−−150-0.009−−250-0.009−−o.r. = of readingThe proposed configuration in the following diagram, however, permits installation in a vertical pipeline. Pipe restrictors or the use of an orifice plate with a smaller cross-section than the nominal diameter prevent the sensor from running empty during measurement.Installation in a vertical pipe (e.g. for batching applications)1Supply tank2Sensor3Orifice plate, pipe restrictions (see Table)4Valve5Batching tankDN815254*********)1501)2501)∅ Orifice plate, pipe6 mm10 mm14 mm22 mm28 mm50 mm65 mm90 mm150 mm restriction1) only Promass FOrientationMake sure that the direction of the arrow on the nameplate of the sensor matches the direction of flow (direction in which the fluid flows through the pipe).VerticalRecommended orientation with upward direction of flow (View V). When fluid is not flowing, entrained solids will sink down and gases will rise away from the measuring tube. The measuring tubes can be completely drained and protected against solids build-up.HorizontalThe measuring tubes must be horizontal and beside each other. When installation is correct the transmitter housing is above or below the pipe (View H1/H2). Always avoid having the transmitter housing in the same horizontal plane as the pipe.Please note the special installation instructions! see Page16In order to ensure that the maximum permissible ambient temperature for the transmitter (–20...+60 °C, optional –40...+60 °C) is not exceeded, we recommend the following orientations:m = For fluids with low temperatures, we recommend the horizontal orientation with the transmitter head pointing upwards (Fig. H1) or the vertical orientation (Fig. V).n = For fluids with high temperatures, we recommend the horizontal orientation with the transmitter head pointing downwards (Fig. H2) or the vertical orientation (Fig. V).Special installation instructions for Promass F"Caution!The two measuring tubes for Promass F are slightly curved. The position of the sensor, therefore, has to be matched to the fluid properties when the sensor is installed horizontally .Promass F, installed horizontally1Not suitable for fluids with entrained solids. Risk of solids accumulating.2Not suitable for outgassing fluids. Risk of air accumulating.HeatingSome fluids require suitable measures to avoid loss of heat at the sensor. Heating can be electric, e.g. with heated elements, or by means of hot water or steam pipes made of copper. "Caution!•Risk of electronics overheating! Consequently, make sure that the adapter between the sensor andtransmitter and the connection housing of the remote version always remain free of insulating material. Note that a certain orientation might be required, depending on the fluid temperature see Page15.•When using electrical heat tracing whose heat is regulated using phase control or by pulse packs, it cannot be ruled out that the measured values are influenced by magnetic fields which may occur, (i.e. at valuesgreater than those permitted by the EC standard (Sinus 30 A/m)). In such cases, the sensor must bemagnetically screened (except for Promass M).The secondary containment can be shielded with tin plates or electric sheets without privileged direction(e.g. V330-35A) with the following properties:–Relative magnetic permeability µr≥ 300–Plate thickness d ≥ 0.35 mm•Information on permissible temperature ranges →Page18Special heating jackets which can be ordered as accessories from Endress+Hauser are available for the sensors.Thermal insulationSome fluids require suitable measures to avoid loss of heat at the sensor. A wide range of materials can be used to provide the required thermal insulation.Zero point adjustmentAll Promass measuring devices are calibrated with state-of-the-art technology. The zero point determined inthis way is imprinted on the nameplate. Calibration takes place under reference operating conditions.→Page10ff.Consequently, the zero point adjustment is generally not necessary for Promass!Experience shows that the zero point adjustment is advisable only in special cases:•To achieve highest measuring accuracy also with very small flow rates.•Under extreme process or operating conditions (e.g. very high process temperatures or very high viscosityfluids).Note the following before you perform a zero point adjustment:•A zero point adjustment can be performed only with fluids that contain no gas or solid contents.•Zero point adjustment is performed with the measuring tubes completely filled and at zero flow(v = 0 m/s). This can be achieved, for example, with shut-off valves upstream and/or downstream of thesensor or by using existing valves and gates.–Normal operation → valves 1 and 2 open–Zero point adjustment with pump pressure → Valve 1 open / valve 2 closed–Zero point adjustment without pump pressure → Valve 1 closed / valve 2 openZero point adjustment and shut-off valvesInlet and outlet runs There are no installation requirements regarding inlet and outlet runs.Length of connecting cable Max. 20 meters (remote version)System pressure It is important to ensure that cavitation does not occur, because it would influence the oscillation of themeasuring tube. No special measures need to be taken for fluids which have properties similar to water undernormal conditions.In the case of liquids with a low boiling point (hydrocarbons, solvents, liquefied gases) or in suction lines, it isimportant to ensure that pressure does not drop below the vapour pressure and that the liquid does not startto boil. It is also important to ensure that the gases that occur naturally in many liquids do not outgas. Sucheffects can be prevented when system pressure is sufficiently high.Consequently, it is generally best to install the sensor:•downstream from pumps (no danger of vacuum),•at the lowest point in a vertical pipe.。
FU80-胆机中的战斗机
FU80-胆机中的战斗机xxxxFU80-胆机中的战斗机经过几个月的努力，先后试验了N种电路，我的FU80终于完成了，由于FU80工作电压高，灯丝电流大11A，发热量大，所以这次比较谨慎，全部过程是用示波器和假负载进行调试的。
为便于调试，我是做了一段1000HZ的音频用电脑播放进行调试。
电路输入级开始用的是6N8P SRPP+6P3P推动，经试验推动不足，实测FU80功率输出只有8~10瓦，如果用CD机播放功率可能大些。
后改用6N9P+6P3P推动，功率略有提高，还是不满意，之后又在另一个声道改用6J4P+6P3P推动，这次增益足够，接上喇叭试听，音量电位器只能转动1毫米，要么是无声，要么是震耳欲聋，调整了6J4P的廉栅极电压到100伏，接上10K 负反馈后，增益降低，用电脑播放一段发烧碟，效果不错，原来6J4P的声音也是这么甜美，点上一只烟，靠在椅子上，凝视着音箱开始慢慢的品位，这时看到音箱前面的一块瓷砖在震动，心想可能是瓷砖松了吧，没有在意，过了一会儿音箱也开始震动，又一想可能是音箱没放平吧，只顾欣赏音乐，仍是没有在意，片刻之后，桌子开始震动，桌上立着的机箱也开始大幅度震动，观看示波器调到最大分辨率波形也未见异常，声音也正常，心想这可能就是寄生震荡吧，如果不是次声波就是超声波，因为是低频，次声波的可能性大些，马上关机，待管子冷却后再次开机，现象依旧，负反馈加大到20K后现象消除，考虑到负反馈太大会影响音质，负反馈还是恢复到10K，重新调整了6J4P的廉栅极电压，发现廉栅极电压调到60伏时比较稳定，调到100伏时就容易产生寄生震荡。
由于买到了第2天的车票，匆忙改完另一声道后回家过春节。
春节过后，仔细分析觉得如果不用变压器偶合，推动级无须用6P3P，于是又改为6N8PSRPP+6N8P/2+6N8P/2两级放大推动，增益足够，功率可以做到90W，效果也是很好，后又改为6N8P/2阴极输出，听感也是不错。

LC80维修经验
在我們這個城市，我幾乎認識所有大牌的修理師傅，他們在這個行業摸爬滾打十幾二十年，有靈性的都成為了頂尖的高手，好喝酒的我請他們吃飯，好女人的我請他們泡妞，成為他們的朋友。我一般在他們的修理廠修車，大型的修理廠業務比較多，一般以換件為主，修理工不會為修車動多少腦筋，80的車門玻璃就像老男人的前列腺，電機多病而無力，據說也是通病。通常解決的辦法是打表板蠟潤滑玻璃導軌和換升降器電機，升降器電機豐田車好多是通用的，但分左右，我的朋友幫改了一下，左右都可用。去年夏天，我讓朋友從廣東發一個電機，拆車件，60元。剛好要出差了，就委托一個大型修理廠的老板去接貨并安裝，因為我們的公車定點在他那里修。他讓我們的司機去簽單：480元。我接到電話猶豫了5秒鐘還是讓司機簽了，心里說：兄弟，您的利潤率快趕上販毒了。這是我第一次也是最后一次在這里修我自己的車，不是說我如何高尚，實在是不符合我的行事規則，修理廠送的禮品和紅包還是收的。修理工就是一個工種而已，你不能對他的道德品質作很高的要求，所以，看好的車內的物品是必要的。有一個朋友，修車絕對是把好手，但天生賊骨，就喜歡偷修理廠的東西，并且屢教不改，去年進去了。我對老板說：再不發現，就該偷老板娘了。
首先說說化油器，這肯定是一個會引起爭議的問題。壇子里說某高手調化油器如何厲害，我也曾相信，準備將化油器寄給那邊的朋友，讓他帶去調一下，朋友說：沒有那么神！再說，我也不可能將車停了等化油器回來，來回得多少天啊。我的車剛到手時大概是20個油，也算正常。后來在修理廠保養時調了下，18--19個，也滿意了。大概是05年的夏天，車老熄火，我讓修理廠給洗一下，結果第二天早晨，那小工哭喪著臉給我打電話，他拆散裝不起來了，我把電話摔了。郁悶了一天，晚上坐的士回家，跟司機聊起這件事，那司機輕描淡寫的說：那是小事一樁。我說：那馬上掉頭，回修理廠。然后我用一給朔料袋將散了架的化油器打了包，來到一個很不起眼的小店，師傅說：晚上看不清楚，明天來吧。第二天大概花了一個小時，用去一罐化油器清洗劑，一啤酒瓶汽油，手工50元（目前漲到80元）搞定。 油耗經過一年多的測試是15--16.（堵了一股銅絲 ，一般路面感覺不到動力損失）。80的化油器相對來說不是什么技術很先進的東西，每一個城市都有那么一兩個能工巧匠能解決你的問題，只是你沒有找到而已。相信科學吧！話說回來，那用礦泉水瓶洗化油器的辦法確實不錯，效果很好。順便說一句：為避免廣告嫌疑，我不會告訴各位電話，也不代轉化油器去調試。
高压电机运行F级绝缘最高运行温度
高压电机运行F级绝缘最高运行温度之马矢奏春创作F级绝缘最高允许温度是155度，性能参考温度在120度之间。
如果温度不继续上升，电机运行不逾额定电流，就可以长期运行；否则就须检查电机以及改善环境温度（如装置排气扇等）。
绝缘等级是指电动机或变压器绕组采取的绝缘资料的耐热等级。
电动机绕组经常使用的绝缘资料，按其耐热性一般分为A、E、B、F、H五种等级，每一绝缘等级的绝缘资料都有相应的极限允许工作温度，（电机绕组最热点的温度）电机运行绕组绝缘最热点的温度不得超出其规定，否则，将加速绕组绝缘老化，缩短电机寿命；如果温度超出允许值很多，绝缘就会损坏，导致电动机烧毁。
绝缘等级允许最高温度A级 105度E级 120度B级 130度F级 155度H级 180度上述度是摄氏度。
与电动机外壳的温度是有差此外，当外壳达到上述温度时，电动机差未几早已烧了。
电动机的绝缘等级与温升的关系为：A级 55度E级 65度B级 70度F级 85度H级 105度绝缘资料根据热稳定性可分为如下7个等级：1，Y级，90度，棉花2，A级，105度，3，E级，120度4，B级，130度，云母5，F级，155度，环氧树脂6，H级，180度，硅橡胶7，C级，180度以上F级绝缘最高温度是155度，在不超出额定电流时可以长期运行。
F级绝缘电机概况温度80多度是否运行正常？根据分歧绝缘资料耐受高温的能力对其规定了7个允许的最高温度，依照温度大小排列分别为：Y、A、E、B、F、H和C。
它们的允许工作温度分别为：90、105、120、130、155、180和180℃以上.F级可承受155度.所以说运行正常.楼主可以继续观察,只要温度变更不明显,就没有问题.绝缘的耐温是实际温度,和环境温度没有关系.我在试验电机时温度达到120多度很罕见的.楼主说40度,80-40=40,温升才40度,没有问题的.电机使用时间过长,铁心磁化疲劳,绝缘漆有机成分挥发等原因导致电机工作温度会少许升高.如果不放心,可以在停机的时候甩开电源,检测对地绝缘电阻,相间绝缘电阻及三相电阻是否符合要求.如果满足要求,就放心用.运行中如何调整发电机定子温度？发电机冷却有很多方式，一般普遍采取空气冷却。

聚四氟乙烯材料力学性能参数表
1．聚四氟乙烯聚四氟乙烯是用于密封的氟塑料之一。
聚四氟乙烯以碳原子为骨架，氟原子对称而均匀地分布在它的周围，构成严密的屏障，使它具有非常宝贵的综合物理机械性能(表14—9)。
聚四氟乙烯对强酸、强碱、强氧化剂有很高的抗蚀性，即使温度较高，也不会发生作用，其耐腐蚀性能甚至超过玻璃、陶瓷、不锈钢以至金、铂，所以，素有“塑料王”之称。
除某些芳烃化合物能使聚四氟乙烯有轻微的溶胀外，对酮类、醇类等有机溶剂均有耐蚀性。
只有熔融态的碱金属及元素氟等在高温下才能对它起作用。
聚四氟乙烯的介电性能优异，绝缘强度及抗电弧性能也很突出，介质损耗角正切值很低，但抗电晕性能不好。
聚四氟乙烯不吸水、不受氧气、紫外线作用、耐候性好，在户外暴露3年，抗拉强度几乎保持不变，仅伸长率有所下降。
聚四氟乙烯薄膜与涂层由于有细孔，故能透过水和气体。
表14-9聚四氟乙烯性能聚四氟乙烯在200℃以上，开始极微量的裂解，即使升温到结晶体熔点327℃，仍裂解很少，每小时失重为万分之二。
但加热至400℃以上热裂解速度逐渐加快，产生有毒气体，因此，聚四氟乙烯烧结温度一般控制在375～380℃。
聚四氟乙烯分子间的范德华引力小，容易产生键间滑动，故聚四氟乙烯具有很低的摩擦系数及不粘性，摩擦系数在已知固体材料中是最低的。
聚四氟乙烯的导热系数小，该性能对其成型工艺及应用影响较大。
其不但导热性差，且线膨胀系数较大，加入填充剂可适当降低线膨胀系数。
在负荷下会发生蠕变现象，亦称作“冷流”，加入填充剂可减轻蠕变程度。
聚四氟乙烯可以添加不同的填充剂，选择的填充剂应基本满足下述要求：能耐380℃高温即四氟制品的烧结温度；与接触的介质不发生反应；与四氟树脂有良好的混入性；能改善四氟制品的耐磨性、冷流性、导热性及线膨胀系数等。
常用的填充剂有无碱无蜡玻璃纤维、石墨、碳纤维、MoS2、A123、CaF2、焦炭粉及各种金属粉。
如填充玻璃纤维或石墨，可提高四氟制品的耐磨、耐冷流性，填充MoS2可提高其润滑性，填充青铜、钼、镍、铝、银、钨、铁等，可改善导热性，填充聚酰亚胺或聚苯酯，可提高耐磨性，填充聚苯硫醚后能提高抗蠕变能力，保证尺寸稳定等。

成功的交易80%靠心理，只有20%靠方法
—本期荐书：《自律的交易者》
华西证券研究所/王郧
本书的作者马克·道格拉斯是交易行为动力公司的总裁，这家公司位于芝加哥，是一家培训公司。
道格拉斯以前是一位成功的期货经纪人，他结合了自己的经验——包括吃大亏的经验——还有别人的经验，从而总结了一些方法，这些方法可以克服不好的交易行为。
道格拉斯发现：虽然交易的技术在突飞猛进，更多的金融产品被创造出来，但是有一个事实没有改变，那就是只有10%经验丰富的交易者赚了很多钱，其他90%的交易者则再一年又一年地亏损。
因
而他认为：少数赢家和大部分输家之间必定有某种区别。
这种区别在于每周、每月、每年持续一致赚钱的交易者都是自律地进行交易。
当别人询问他们成功的秘诀时，他们都直截了当地说他们一开始也是亏损的，直到他们学会了自律、情绪控制和顺势而为之后，他们才开始持续一致地累积财富的。
道格拉斯在与几千名交易者、经纪人和交易顾问互相交谈提问后积累了大量的案例资料，并通过研讨会和工作坊的形式，将自律的技术公诸于众，而这大概也是他写作本书的初衷吧。
我们在交易中，可能都对股市赢家的名言如“市场永远是对的”、“学会接受亏损”、“顺势而为”、“趋势是你的朋友”、“截断亏损，让利润奔跑”、“只有了解自己，才能了解市场”早已耳熟能详。
然而仔细一想，又觉得这些都很虚不实在，到底应该如何止损？如何顺势而为？如何了解自己并进一步了解市场呢？《自律的交易者》一书会剖析这些交易心理智慧，形成有步骤的学习过程，这个学习过程会领着你走过不同的必经阶段并成功地进入交易状态。
本书会解释什么技术是必须的，为什么你必须学会这些技术，更重要的是告诉你如何学习这些技术。
道格拉斯发现传统文化只会让我们交易亏损，社会灌输给个人的价值观、信念和成功思维方法对于交易来说是不实用的，是不能交易成功的。
交易者失败的原因归咎于以下三个方面：
1、没有技术。
交易者期望值过高，不知道交易环境与其他环境都不同，不知道如何修复心理创伤，也不知道如何消除自己的恐惧感。
2、有限性的信念。
交易者可能会意识到部分会阻碍成功的信念，但无法完全摆脱信念的影响，甚至不愿意直面和处理信念的问题。
3、没有自律。
如同不知道交通规则而过马路的小孩一样，交易者缺乏一些必要的规则和限制来指导交易行为。
详细阐述了交易的困难之后，作者认为改变文化态度和信念，创造自己的市场体验之后，才有可能获得成功。
更进一步地，作者提出了成为成功交易者的三个步骤：首先是提高认机会的能力，而这需要制定有纪律的交易方法和释放过去交易体验形成的消极情绪能量；其次是消除恐惧，执行交易的能力；最后是通过自我评估，累积利润的能力。
“仓位盈利时，害怕亏损的心理导致我们担心市场会拿走我们的钱，迫使我们尽快平仓；仓位亏损时，我们关注的是所有认为这个仓位会赚钱的信息，恐惧心理导致我们不假思索地做出了行动”。
作者以小孩和狗玩耍的体验为例，生动地描述了人的记忆、联想和信念时如何管理环境信息的，以及交易者为什么要学会适应环境，不断学习和更新知识，管理心理能量的重要性。
这也形象地解释了为什么大部分交易者都是“截断利润，让亏损奔跑”,而学习和不断改变，则是交易成功的关键。
作者在书中，详细讲解了多种有效改变的技术，如改变信念系统中的意识，确定信念冲突的方法，向自己提问，用写作技术实现改变等等。
在本书最后一部分，作者提出了如何成为自律交易者的成功步骤这一令所有人都感兴趣的话题。
在道格拉斯看来，交易的本质是自律，而自律是一种心理技术，让你关注于应该学的事和应该做的事，以下七步是必须的：第一步，聚焦于你要学习的知识：关注如何提高赚钱的能力而非赚钱本身；
第二步，处理亏损：在交易前要提前定义亏损，一旦意识到要亏损了，就要立即止损；
第三步，成为某个市场行为方面的专业人士：一开始只选择一个交易系统，一开始只关注一种走势；
第四步，学会如何完美地执行一个交易系统：了解交易系统和市场间的关系，把系统的数字和行为联系起来；
第五步，学会用概率思考：用自己的分析能力和直觉来决定市场的走势；
第六步，学会做到客观：相信一切都有可能，提前决定在每个状况下应该怎么做；
第七步，学会监督自己：包括监督自己的感受和所做出的承诺。
