跪求<针式节流阀>的英文资料,第1张

导致针式节流阀失效的主要原因有:整体式阀杆的阀芯头硬度不够、存在原始裂纹以及原始裂纹在交变载荷作用下的扩张,外力作用使阀杆头挤裂,最终导致阀杆头部失效;对于镶硬质合金阀芯头结构的阀杆,由于阀芯头与阀杆连接的焊接工艺达不到要求,焊接处易脱落或硬质合金阀芯头脆裂,节流通道易堵死。为此,在分析节流阀阀杆机理的基础上,提出相应的改进措施,研究了新的节流阀阀杆。节流阀阀杆采取整体喷焊后,阀杆寿命提高2.5~3倍,彻底杜绝了阀芯头脱落现象,提高了节流阀节流的可靠性。

Impact throttle valve failure caused the main reasons are: the overall first-stem of the valve core hardness enough, and the existence of the original crack crack in the original alternating loads of expansion, forcing the first to stem crowded split, which eventually led valve Failure at the head; Carbide spool set for the first structure of stem, spool valve rod connected to the first and welding technology达不到要求, welding or the easy shedding Carbide spool head of brittle fracture, flow Festival Road easily blocked Therefore, in the analysis of the mechanism of the throttle valve stem on the basis of the corresponding measures for improving the throttle of a new stem Throttle valve stem to the overall spray, stem lifespan of 25 to 3 times that of the complete elimination of the spool first shedding phenomenon, improve the reliability of the throttle expenditure

寿命最长的昆虫:活得最长的昆虫是光亮甲虫(吉丁虫科)。1983年一个至少经历了51年幼虫期的光亮甲虫出现在英国埃塞克斯郡普律特韦尔的一户人家中。

还有: 最长寿的昆虫

1979年的夏季,从美国的卡洛来纳州到纽约,每天晚上都有无数的暗色小虫子从地下飞出来,这就是十七年蝉。它们飞到几乎所有竖立着的目标上,如树木、电线干和建筑物,不一会儿,雄蝉发出欢乐喧闹的叫声,引诱雌蝉,这标志着它们1962年出生后在地下生存了17年,今年到地面上来举行“婚礼”。

绝大多数的昆虫,只有一年或更短的生活史,一般的蝉只有3至9年的生活史,虽然还有一种十三年蝉,在地下生活的时间有17年,使它获得了昆虫世界里最长寿的头衔。

最大和最小的蝴蝶

蝴蝶自古以来位世界各国人民所喜爱,蝴蝶的种类很多,全世界共有14000余种,我国有1300种以上。我国的台湾省是著名的蝴蝶产地,素有“蝴蝶王国”制成,月有蝴蝶400余种。

凤蝶是最大的蝴蝶,也是最美丽的蝴蝶。凤蝶翅上有红、黄、蓝、黑、白各种颜色,五彩缤纷,并构成美丽的斑纹,发出金属的光彩。世界上最大的蝴蝶是南美凤蝶,体长90毫米;翅展270毫米,相当一种中等体型鸟类的翅展。我国最大的凤蝶翅展达150毫米。

最小的蝴蝶是小灰蝶,翅展16毫米。1983年6月,我国昆虫学家马恩沛,在云南西双版纳小勐养大象自然保护区的原始森林里采到一种小灰蝶,翅展长度仅13毫米,创造了最小的纪录。小灰蝶雄雌体色不同,雌蝶通常呈暗色,雄蝶常具有翠、蓝、青、橙、红、古铜等颜色的金属光彩。这类蝴蝶翅膀的正面,斑纹比较平淡,而翅膀的反面,却色彩丰富,远较正面突出。

繁殖最快的昆虫

昆虫往往多子多孙,而繁殖最迅速的是蚜虫。全世界已知蚜虫种类有2000多种,我国估计有600种以上。

蚜虫的生活是与众不同的,有卵生,有孤雌卵胎生(已知母蚜虫部经过交配能生出小蚜虫),雌蚜虫有的有翅,有的无翅。以棉蚜为例:在温度适宜的情况下,4-5天就能繁殖一代。作“母亲”的生下“女儿”才4-5天就做起“外婆”起来了,所以他们经常是六七代同堂。一只棉蚜虫一年能繁殖二三十代。有人估计,一只孤雌胎生的棉蚜自6--11月中旬的150天内,如后代都存活,那可达到672623338074292603508个。如果这些蚜虫平铺起来,相当于地球面积的13倍。在自然界中,蚜虫上述惊人的繁殖数字并不存在,否则我们将被蚜虫“埋掉”了。

寿命最短的昆虫

如果“寿命”两字在昆虫中是指成虫生活的天数而言,那么蜉蝣是昆虫中最短寿的。我国古代早有记载:“蜉蝣,……朝生暮死”。确实,多种蜉蝣成虫的寿命只有几小时,寿命最长的不超过一星期。

蜉蝣的交尾在“婚配”中进行。傍晚时刻,水面上常积聚着大群刚孵化的蜉蝣,在飞行中,一只熊虫会突然抓住一只雌虫进行交尾。交尾后,雌虫产卵在水中。蜉蝣的卵生有一些细线,在水中这些盘着的细线伸开。有些细线尖端有吸盘,可以是卵牢牢地固着载河底,以便安身立命。

最毒的甲虫

斑熬,别名“斑猫”、“龙蚝”、“地胆”,属鞘翅目芫青科斑螯属,是最毒的甲虫。全世界约有斑螯2300多种,我国则有29种。斑螯全身披黑色绒毛,翅细长椭圆形,质地柔软,体长为11—30毫米,翅基部有两个大黄斑,中央前后个有一**波纹状横带,足具有黑色长绒毛,危害大豆、花生、茄子等作物。

斑螯多群集取食,成群迁飞。当它遭到惊动时,为了自卫,便从足的关节处分泌出**毒液。此**毒液内含有强烈的斑螯素,其毒性甚强,能破坏高等动物的细胞组织,与人体接触后,能引起皮肤红肿发泡。

最原始的昆虫

嘴原始的昆虫,是原尾虫。它们是一些白色或**的小虫,最大的个体只有2毫米左右。性喜潮湿,常生活在石块、瓦片和草根下。

凡是昆虫,其头部都有一对触角,胸部由3对足,翅2对,长具单眼和复眼。但是原尾虫无翅,无眼,也无触角,它们常把第一对足高举在头的上方,代行触角的机能。幼虫初孵化时腹部9节,再生长过程中增生3节。这些特征与其它昆虫不同,表现了它们的原始性。人们对原尾虫的研究,在昆虫学上有独特的意义,是昆虫学基础理论研究的一部分。然而,解放前,这项工作在我国完全空白,人们因而认为我国是没有原尾虫的。1956年,北京农业大学杨集昆教授最先采到我国原尾虫标本,在我国昆虫学界传为佳话。

最重的昆虫

最重的昆虫是分布于赤道非洲的花金龟科大甲虫。个头最大的叫巨花金龟,其雄虫从触角尖到腹部末端的长度为11厘米,重70至100克,雌虫身长较短。

最长的昆虫

世界上有记载的最长的昆虫是生活在婆罗州雨林地区的一种棒状虫。英国伦敦的自然历史博物馆保存有已知最长的昆虫标本。该标本身长328厘米,若包括腿在内,全身可长达546厘米。在野外时常发现此类昆虫断腿,原因是当它蜕皮时,过长的腿极易碰断。

飞得最快的昆虫

任何一种昆虫,包括鹿马蝇、天蛾、马蝇和几种热带蝴蝶在内,其持续飞行的最高速度为每小时39公里。飞得最快的昆虫是澳大利亚蜻蜓,它短距离的冲刺速度可达每小时58公里。

看看吧~~~~

广告打的那些减肥产品是没用的,商家都是为了赚钱,不能长久保持的,还有很多副作用。比如内分泌紊乱,精神亢奋,影响睡眠,抑制食欲,精神恍惚,便秘,长痘长斑等等。

吃进的热量比消耗的少,加上多运动才能减肥。

每天有氧+无氧运动穿插着做一小时,比如先快跑5分钟+快走10分钟。或者在家狂跳舞一小时,舞姿随便 要能跳出汗来的那种。

吃饭早餐吃好,中餐适量,晚餐少吃,过晚上8点以后不要吃任何东西 除了水。

减肥只能是自己勤快别贪吃才行的。肉不是一天长出来的,减也要慢慢来,身体健康才是王道,保持才是正道。

减肥没有捷径,只能是:管住嘴,迈开腿!

唯有少吃多动才能健康减肥。并且一定要坚持!

平时多注意时时收腹,多按摩腹部,练习腹部呼吸法。

当然,您也可以到网上找一下 湖南女报账员减肥成功,不料获刑12年 的资料来借鉴一下,希望对你有所帮助。

Nowadays the pioneers of the clutch disc, clutch disc is more pieces of it until 1925 later The multi-gear clutch main advantage is that car started the clutch engagement is no impact on the smooth Early in the design, layout design, according to slice pairs of a steel plate with a bronze blanks Using the friction pair of pure metal, put them in oil, can achieve more satisfactory performance

As the power to combustion in mechanical transmission automobiles, clutch is as an independent assembly The clutch is usually served in the engine and transmission, the active part between connected with engine flywheel, driven and transmission Various types of cars for widespread adoption of friction clutch, in fact, is a kind of depend on their part, driven to relay the friction between the power and the separation The major function of the clutch is cut off and the realization of the engine and transmission, to ensure smooth, stable car When the shift in the engine and transmission of separation, reduce transmission gear shift between the impact, Work in the dynamic load is larger, can limit the transmission of maximum torque, in order to prevent the transmission parts of a damaged by overload, Reducing effectively the transmission of the vibration and noise

In the early development of clutch structures, the most successful conical clutch It was the prototype design in 1889 German Daimler company production of steel wheel on the car It is to make the engine flywheel hole taper as clutch active The taper clutch scheme continues to the middle of the twentieth century, when the manufacture, cone-shaped clutch friction relatively simple, easy to repair It was used LuoMao friction material, leather belt, etc Then have been hoof - drum clutch, its structure in the solid-bowl clingy reaches hoof Hoof - drum clutch friction components with wood, leather belt is such, shoe - drum clutch weight is light cone clutch Whatever tapered clutch or hoof - drum clutch, easy to cause the separation is not complete appear even Lord, follower cannot separate self-locking phenomenon

Years of practical experience and technical improvement makes people tend to preferred dry friction clutch single chip, because it has driven part of inertia, good heat, simple structure, convenient adjustment, compact size, etc, but also because completely in structure, already can take action to smooth, so now junction disc is widely used in large, medium and small various models

Now monolithic dry type clutch in structural design is quite perfect Using the axial elastic platen, improve the clutch of comfort The clutch platen assembly installed in reverse, prevent the transmission system of shock of torsional resonances, reduced the transmission system of noise and load

As the car comfort requirements, clutch in original basis has been obtained by car, by continuously improved by increasing the quality of the flywheel has double shock absorber, can turn better reduce transmission noise

Due to heavy clutch, commercial, engine power tends to large-scale increasing, but the size of the space increased clutch allows the use of limited, clutch, cool 1, increase conditions to improve ability, preaching clutch torsion life-span, simplify the operation has become the development trend of the heavy clutch In order to improve the ability of torsion, in heavy vehicles can be used on double dry type clutch Theoretically, in the same radial dimensions, biplate clutch torsion ability and the service life is 2 times of single chip But other objective factors, the actual effects of low value than others

In recent years, the wet clutch on technology improvement, some heavy cart in abroad and start using multiple wet clutch Compared with dry type clutch, due to the use of the pump are forced cooling, friction surface temperature is lower than 93 degrees Celsius (not), therefore, long time also does not start sliding friction loss Refer to the information at home and abroad were told that this clutch can use dry type clutch of 5-6 times, but the advantages of the wet clutch play must be in a temperature range, more than it can achieve a temperature range will play a negative effects Now this technology is not perfect
