柴油锅炉的工作原理?

说明这种锅炉是使用柴油作为热量来源,加热锅炉内部的受热部件,然后再去加热锅炉受热管内的水,直至将水加热到饱和状态或过热状态,再将蒸汽送至用户处供利用。从发热量来看,柴油的热值要比普通燃煤高很多,但价格也贵,只有在特定场合例如野外或需要临时使用时才会使用柴油作为燃料。

ppr是什么材料

ppr是英文无规共聚聚丙烯俗称三型聚丙烯。PPR是英文无规共聚聚丙烯(Polypropylene-Random)的简称。俗称三型聚丙烯。PPR管是镀锌管、UPVC给水管、铝塑管、PE管、PE-X管、PE-RT管的更新换代产品。由于它使用无规共聚技术,使聚丙烯的强度,耐高温性得到很好的保证,从而成为水管材料的主力军。卫生健康环保。聚丙烯是环保材料,可用作饮用水输送。接头用热熔连接,成为一体,百分百无渗漏,其他材料用丝口连接,其防渗性较逊,也避免了胶水粘接的有毒性。输送阻力小。价格便宜适中。使用寿命长,按国家标准GB/T18742生产和使用时可以使用50年。PPR是三型聚丙烯的简称,采用热熔接的方式,有专用的焊接和切割工具,有较高的可靠性。价格也很经济。保温性能也很好,管壁也很光滑。不包括内外丝的接头。PPR管材与传统的铸铁管、镀锌钢管、水泥管等管道相比,具有节能节材、环保、轻质高强、耐腐蚀、内壁光滑不结垢、施工和维修简便、使用寿命长等优点,广泛应用于建筑给排水、城乡给排水、城市燃气、电力和光缆护套、工业流体输送农业灌溉等建筑业、市政、工业和农业领域。PPR管正式名为无规共聚聚丙烯管,是目前家装工程中采用最多的一种供水管道。

紫外线杀菌需要杀多久才能达到杀菌效果?

紫外线指数是指一天当中太阳在天空中的位置最高时(也即中午前后),到达地面的太阳光线中紫外线辐射对人体皮肤的可能损伤程度。紫外线指数一般用0-15表示。通常规定,夜间紫外线指数为0,在热带或高原地区、晴天无云时,紫外线最强,指数为15。可见紫外线指数值越大,表示紫外线辐射对人体危害越大,也表示在较短时间内对皮肤的伤害愈强。 有时又可将紫外线指数分为5级发布,即指数值为0、1、2时,为1级,表示太阳辐射中紫外线量最小,对人体基本没有什么影响;紫外线指数为3、4时,为2级,表示太阳辐射中的紫外线量比较低,对人体的影响比较小;紫外线指数为5、6时,可称3级,表示紫外线辐射为中等强度,对人体皮肤有一定程度的伤害;紫外线指数为7、8、9时,可视为4级,表示紫外线辐射较强,对人体危害较大,应注意预防;外出应戴太阳帽、太阳镜或遮阳伞,也可涂擦一些防晒霜(SPF指数应大于15)。当紫外线指数≥10时,可视为5级,表示紫外线辐射最强,对人体危害最大,人们应减少外出时间(特别是中午前后),或采取积极的防护措施。 总的来说紫外线消毒灯透过的是石英玻璃,具体的请您看下面说明。 紫外线是指波长在200nm~380nm之间的太阳光线,包括3类:UV-A波长为315nm~380nm,UV-B波长为280nm~315nm,UV-C波长200nm~280nm。到达地球表面的太阳光线(290nm—2000nm)中紫外线约占13%,其中UV-A占97%,UV-B占3%,UV-C接近于0。对人皮肤损伤的只有UV-A、UV-B。通过特殊工艺制成的UV-C紫外线灯,用来进行消毒灭菌。 其中真正具有杀菌作用的是uv-C波紫外线,254nm左右的紫外线最佳。紫外线可以杀灭各种微生物,包括细菌繁殖体、芽胞、分支杆菌、病毒、真菌、立克次体和支原体等,具有广谱性。 其杀菌原理是通过紫外线对细菌、病毒等微生物的照射,以破坏其机体内DNA(去氧核糖核酸)的结构,使其立即死亡或丧失繁殖能力。石英紫外线灯具有优势,那么,如何识别真假。不同波段的紫外线杀菌能力不同,只有短波紫外线(200-300nm)才能对细菌有杀灭能力,其中在250-270nm范围杀菌力最强,不同材料制造的紫外线灯成本和性能也不一样。真正高强度、长寿命的紫外线灯必需是采用石英玻璃制造,这种灯也叫石英杀菌灯,它分两种类型:高臭氧型和低臭氧型,在消毒柜一般采用高臭氧型,这也是石英紫外线灯相对其他紫外线灯的一个显著特点,此外,它产生的紫外线强度高,是高硼灯的1.5倍以上,并且,紫外线辐射强度寿命长。最可靠的分辨方法是用紫外线辐照度计254 nm探头来测,同样功率,254 nm紫外线强度最高的是石英紫外线灯。其次是高硼玻璃紫外线灯,高硼玻璃灯紫外光强度很容易衰减,它点灯数百小时后其紫外光强度就大幅下降,降到初始时的50%-70%。在用户手上,虽然看到灯管还是亮的,但它可能已不起作用了。而石英玻璃的光衰减程度要远小于高硼灯。涂了荧光粉的灯管,不管是用何种玻璃制造都不可能发出短波紫外线,更不可能产生臭氧,因为经荧光粉转换发出的谱线,波长最短为300 nm附近,在消毒柜里经常能看到的是灭蚊灯,只能产生365nm谱线和一部分蓝色光,它的功能除了能把蚊子吸引过来之外,是根本没有消毒作用的。----高硼玻璃紫外线灯和石英紫外线灯在外观上比,石英紫外线灯一般不能装铝盖灯头,灯头材质用塑料,胶木或陶瓷,灯头外径要比玻璃管粗;高硼玻璃都可采用自动化程度较高的圆封的生产工艺,其工艺与日光灯生产一样,可用铝灯头。 ----石英玻璃熔点高,膨胀系数低,如果同时放在火中加热,高硼玻璃熔点低。加温后同时放在水中急冷,不会碎裂的是石英玻璃。对于一些使用普通玻璃管制造的所谓"紫外线灯",这种灯是不含紫外线的,用一个简单的方法测试:把这种灯在节能灯或日光灯旁边点亮,它不能激化管内荧光粉发光,就可证实它是名符其实的假冒伪劣产品。

逐浪之爱大结局

《逐浪之爱》大结局:坏人掳走了Sammy,甚至要放火毁了她。Mik为了救Sammy,不仅身负重伤,而且亲眼看到好朋友在他面前失去生命。就在所有人都以为坏人不会再出现的时候,顽强的坏人又再次出现了Mik的办公室,还差点毁了Mik。在这部剧中,Mik几乎每集都会被坏人男二追赶,就算是落入海里,脸部差点毁容,坏人依旧可以精准地找到他,让人不得地怀疑坏人在Mik的身上装了定位器。《逐浪之爱》确实有些高开低走,前期的动作打斗戏很精彩,甚至连女主Sammy都是战斗力满分,但是全剧的动作戏份过多就显得很突兀,甚至抢了Mik和Sammy谈恋爱的风头。虽然编剧给Mik和Sammy安排了一个浪漫的海边求婚结局,但是观众却丝毫不买账。一些观众吐槽坏人的戏份真的太多了,每集至少要出现十分钟,简直比Mik的戏份还重。同类型电视剧:1、《强悍媳妇》:讲述了为了照顾已故姐姐的儿子和为其复仇,女主和姐夫契约结婚,并在姐姐曾经的婆家大杀四方开启复仇模式的故事,而与姐夫也就是男主之间相互救赎的爱情故事更是在契约婚姻的极限拉车中让观众上头不已。整部剧是以爱情轻喜剧定位,所以女主的个性是比较张扬可爱的,如剧名一般彪悍的作风确实让人哭笑不得的同时又大为快意。2、《劫心恋人》:该剧主要讲述了男女主先婚后爱的情感故事,秉承了泰剧一如既往的狗血和套路,让人越看越上头。男主在剧中是富家大少爷,暗恋女主而未表明,但因某种原因两人结婚,宠妻的男主人设,着实让人上头不已。

余晖残橙原理

余晖残橙原理光的色散现象。余晖残橙”是一种常见的自然景观,通常出现在日落或日出时分,当太阳处于地平线以下时,太阳的光线会穿过大气层中的尘埃和水分,使得天空呈现出橙红色或者紫红色。这种现象的原理是光的色散现象,太阳光中的不同波长的光线在穿过大气层时会发生不同程度的偏折和散射,而橙色和红色光线的波长较长,所以相对于其他颜色的光线来说,它们更容易穿透大气层,因此在日落或日出时,太阳光线穿过大气层时,橙色和红色光线更容易被保留下来,形成了橙红色的天空。

解释折射率的色散现象

解释折射率的色散现象如下:色散是复色光分解为单色光而形成光谱的现象。色散可以利用棱镜或光栅等作用为色散系统的仪器来实现。如复色光进入棱镜后,由于它对各种频率的光具有不同折射率,各种色光的传播方向有不同程度的偏折,因而在离开棱镜时就各自分散,形成光谱。例如太阳光通过三棱镜后,产生自红到紫循序排列的彩色连续光谱。复色光通过光栅或干涉仪时,由于光的衍射和干涉作用,也能使各种色光分散。光的色散(dispersion of light)指的是复色光分解为单色光的现象。由两种或两种以上的单色光组成的光(由两种或两种以上的频率组成的光),称为复色光。不能再分解的光(只有一种频率),称为单色光。一般让白光(复色光)通过三棱镜就能产生光的色散。对同一种介质,光的频率越高,介质对这种光的折射率就越大。在可见光中,紫光的频率最高,红光频率最小。当白光通过三棱镜时,棱镜对紫光的折射率最大,光通过棱镜后,紫光的偏折程度最大,红光偏折程度最小。这样,三棱镜将不同频率的光分开,就产生了光的色散。原理:色散的原理是光的折射。在自然界中,太阳光是白光。当太阳光的白光通过棱镜后被分解成各种颜色的光,假如用白屏来承接,在白屏上就形成一条彩色的光带,这些光带的颜色依次是红、橙、黄、绿、蓝、靛、紫。

三棱镜色散原理

三棱镜的原理:因为同一种介质对各种单色光的折射率不同,所以通过三棱镜时,各单色光的偏折角不同。因此,白色光通过三棱镜会将各单色光分开,形成红.橙.黄.绿.蓝.靛.紫七种色光即色散。光学上将横截面为三角形的透明体叫做三棱镜,它是由透明材料作成的截面呈三角形的光学仪器,属于色散棱镜的一种,能够使复色光在通过棱镜时发生色散。阳光是复色光,有红橙黄绿蓝靛紫这些不同频率的光。这些对于同一介质的折射率不同,所以一束光进入三棱镜后,发生偏转角度不同的折射(光的折射定律:入射角的正弦正比于折射角的正弦

交流接触器的常开,常闭是什么意思?

当接触器线圈通电后,线圈电流会产生磁场,产生的磁场使静铁芯产生电磁吸力吸引动铁芯,并带动交流接触器点动作,常闭触点断开,常开触点闭合,两者是联动的。当线圈断电时,电磁吸力消失,衔铁在释放弹簧的作用下释放,使触点复原,常开触点断开,常闭触点闭合。直流接触器的工作原理跟温度开关的原理有点相似。NO表示的常开,NC表示的是常闭。扩展资料:交流接触器动作的动力源于交流通过带铁芯线圈产生的磁场,电磁铁芯由两个「山」字形的幼硅钢片叠成,其中一个固定铁芯,套有线圈,工作电压可多种选择。为了使磁力稳定,铁芯的吸合面加上短路环。交流接触器在失电后,依靠弹簧复位。永磁交流接触器是利用磁极的同性相斥、异性相吸的原理,用永磁驱动机构取代传统的电磁铁驱动机构而形成的一种微功耗接触器。半导体接触器是一种通过改变电路回路的导通状态和断路状态而完成电流操作的接触器。真空接触器是接点系统采用真空消磁室的接触器。参考资料:百度百科-接触器

空开跳闸交流接触器为什么还吸着

  1:空开只作为一次线路(接触器负荷)的电流保护。  2、交流接触器所带的设备(电机等)或线路发生短路后出现的特殊现象。  接触器分为交流接触器(电压AC)和直流接触器(电压DC),它应用于电力、配电与用电。接触器广义上是指工业电中利用线圈流过电流产生磁场,使触头闭合,以达到控制负载的电器。  接触器的工作原理是:当接触器线圈通电后,线圈电流会产生磁场,产生的磁场使静铁心产生电磁吸力吸引动铁心,并带动交流接触器点动作,常闭触点断开,常开触点闭合,两者是联动的。当线圈断电时,电磁吸力消失,衔铁在释放弹簧的作用下释放,使触点复原,常开触点断开,常闭触点闭合。直流接触器的工作原理跟温度开关的原理有点相似。

光的色散知识点

光的色散知识点有光的三原色是红绿蓝,等比例混合后为白色。颜料的三原色是红黄蓝,等比例混合后为黑色。透明物体的颜色由它透过的光决定等。 光的色散考点 1.光的色散:白光经三棱镜折射后,在白屏上出现从上到下红、橙、黄、绿、蓝、靛、紫依次排列的彩色光带,这种现象叫做光的色散。三棱镜的色散实验使白光成了红橙黄绿蓝靛紫。该实验证明了:白光不是单一色光,而是由许多色光混合而成的 2.色光的混合 色光的三原色:红、绿、蓝。等比例混合后为白色。 3.物体的颜色 ①颜料的三原色:品红、黄、青(红、黄、蓝),等比例混合后为黑色。 ②透明物体的颜色是由它透过的色光决定的。 ③不透明体的颜色是由它反射的色光决定的。 ④白色的不透明体反射各种色光。黑色的不透明体吸收各种色光。 4.透明物体的颜色由它透过的光决定。不透明物的颜色由它所反射的光决定。 光的色散基本概念 光的色散指的是复色光分解为单色光的现象。牛顿在1666年最先利用三棱镜观察到光的色散,把白光分解为彩色光带(光谱)。 色散现象说明光在媒质中的速度(或折射率n=c/v)随光的频率而变。 在光学中,对于不同的波长,介质的折射率n(λ)也不同,这令白光在折射时,不同颜色的光线分开,这种现象就称为光的色散。一般波长越小,折射率越大:紫色光折射率大,红色光折射率小。 同学们要记得,不同于光的折射和光的反射原理,光的色散证明了光具有波动性。

紫外线UVC是怎么杀菌的?

紫外线消毒原理是利用280nm以下的UVC波段高能深紫外光子直接破坏微生物(细菌、病毒和病原体)的DNA或RNA遗传物质,通过阻断其繁殖来实现高效快速的广谱灭菌效果。紫外线杀菌距今差不多有一个世纪的历史,即沸水消毒之后,另外一种物理消毒方法,它的好处在于不向水中、空气中、物质上增加任何物质,没有副作用,这是它优于氯化消毒的地方,经过近100多年的发展,紫外线消毒系统设备(包括紫外灯、镇流器、紫外感应器、灯管清洗装置及反应器控制系统、第三代半导体全光谱UVC紫外芯片)的生产技术发生了很大的变化,至善智能推出的新的紫外消杀机器人,采用的芯片技术和智能机器人技术、大数据等技术的加入,解决了传统紫外消杀使用寿命短的问题,机器人技术很好的给予消杀的可移动性,不在是固定消杀的问题,很大程度上加大了紫外消杀的可应用性,相对于有刺激性味道的酒精消杀,我更喜欢这种无毒、无味的消杀方式。
