die casting machine-Information on Aluminium Gravity Die Casting Process
Gravity die castdie casting machineing is one of the standard processes for the manufacture of high-integrity automotive castings。 It represents proven and absolute precision technology for the productionMulti slider die casting machine of large batch quantities。 This process is used in carousel casting units or in shuttle technique particularly for the manufacture of engine castings。 Optimum heat dissipation from the solidifying casting through the die leads to short solidification times。 This results in castings which have good mechanical properties， especially after an additional heat treatment。

In addition to producing ever more complicated cylinder heads for petrol and diesel engines， this is also used for the manufacture of diesel engine blocks with cast-in grey iron liners。
Process description
In processes， the melt is metallurgical treated in the holding furnace， which is positioned near the dies?
The quantity of melt for one is transported in a ladle and poured into the riser system of the mould by tilting the ladle。 The melt fills the mould cavity smoothly from the bottom up until it appears in the risers positioned above the casting。
In the example shown， the casting of a cylinder head， the mould filling and solidification Conditions can be influenced by the design of the gating system and the risers in the top core。 Directional solidification can be forced by using water cooling in the bottom of the die。
Low pressures die casting
Low pressure die casting is a well-known process， especially for aluminium wheels in passenger cars。 The process is also used in the production of big V-engine blocksDie casting in hypereutectic aluminium alloys and in the casting of air-cooled cylinder heads for motorzinc die casting cycles。 Mould filling is controlled by regulating the pressure in the casting furnace。 The melt flows through the riser tube which is positioned under the melt surface of the furnace and fills the mould very smoothly with clean melt from the bottom up。 After mould filling， solidification starts from the opposite end of the mould in the direction of the tubezinc die casting。 By increasing the pressure in the casting furnace， good feeding is guaranteed。 Cycle times are long duedie casting machine to the fact that the casting is connected to the big melt volume by the riser tube during solidification。
High pressures die castings
Filling speed and intensification pressure differentiates high-pressure die casting from most other processes。
After liquid metal is transferred toDie casting the shot sleeve the plunger slowly closes to shut off the filling port。
The plunger is then moved towards the die at a controlled but high speed in order to fill the die cavity。
With the potential for highly automated operation， the high-pressure dieMulti slider die casting machine casting ( process is capable of extremely high levels of productivity。 HPDC machines are size rated by the closing force。。。

Rubber Parts-Capabilities of Custom Rubber Parts

If there is a moCustom Mold Rubber Partsre versatile material that we use in our daily lives， in almost everything， it has to be rubber。 Like steel， there are limitless possibilities with rubber。 Rubber and elastomeric parts have natural elasticity making them very adaptable and excellent for mechanical uses。 They are tensile， tear-resistant， have resilience and can elongate。 Rubber is adaptable， flexible and can be customized and molded to fit into anything that requires it - for this reason， custom rubber parts are used in all kinds of industries especially where elastomeric parts are key components like aerospace， transportation， medical， marine， oil & gas and even semiconductors。

外牆清洗-居家清潔六種物品需重視

提起居家清潔，許多人都不屑一顧，居家清潔不就是掃地、拖地、擦桌子嘛，有什麽需要注意的。其實不然，在日常生活中最容易滋生細菌影響家人身體健康的地方往往並不是地面、餐桌，而是一些經常被大家忽略的物件。

衛浴間的物品極易成爲細菌滋生的溫床。潮濕的浴簾應每周清洗一次，清洗時多放一些洗衣液，最好用熱水清洗，之後徹底曬幹。或者每次使用後及時將浴簾展開，以減少其濕潤度。淋浴噴頭也極易滋生細菌，有研究表明，每3個噴頭中就有1個被汙染，分枝杆菌能滲入肺部，致人疲憊、虛弱和氣短。日常生活中，大家應該辦公室清潔每周用硬毛刷清洗噴頭。

客廳的部分物件地毯清洗也需引起居民足夠重視。遙控器是居民在家中休閑時間接觸頻率相對較高的物件，事實表明，約70%的遙控器含有致病細菌。建議大家每周用酒精濕巾徹底擦拭一次，或者使用噴霧式洗滌劑。地毯裏的髒物是很難被清除家事清潔掉的，再好的吸塵器也無法清除深藏在地毯裏的髒物。最好的辦法就是盡量少用地毯，改用實木、油氈或瓷磚外牆清洗的地板。70%的盆栽植物會散發出黴菌孢子，人體吸入黴菌孢子會出現喉嚨痛、鼻塞等狀況。建議每次給盆栽澆水後，將地毯清潔其在室外晾曬至土壤表面幹燥。

枕頭往往是臥室內細菌最活躍的地方，必須經常對其進行清洗，另外化纖枕頭比羽毛枕更加容易滋生螨蟲，將枕頭換成羽毛芯，套上細密的枕套，不僅能防止竄毛，還能降低居民吸入有害物質和過敏原的幾率。

感情挽回-婚後5大感情“危險期”

　　婚姻生活大多會遇到5個危險期感情復合，學會巧妙處分手復合理，有助順利跨過這5道坎。婚後5大感情“危險期” 你都會經曆。

　　結婚1年後

　　結婚一年後，兩人開始面對瑣碎的現實，彼此的缺點也暴露出來，如果沒有做好心理准備，柴米油鹽的日子很可能讓人感到不適應。重慶家裏家外首席婚姻分析師瑜峰老師指出，夫妻婚前應明白，婚姻不是天堂，對于蜜月期後的心理落差要有充分的認識，對愛人也要學會包容。

　　妻子孕期

　　長達1年的孕期，難免帶來“性危機”，一些男性可能會因爲生理需求出軌。要想避免這一情況，夫妻對孕期性生活要有科學的認識，避開危險的孕初期和後期，掌握好技巧。其次，要加強溝通，讓肚子裏的孩子成爲感情的紐帶。

　　孩子剛出生

　　孩子出生後，夫妻的注意力都集中在孩子身上，性生活也大打折扣，加上照顧孩子的辛勞和經濟上的壓力，夫妻關系容易緊張。瑜峰表示，可以請長輩幫忙照看孩子，還要正視夫妻性生活質量下降的問題。

和合術　　七年之癢

　　此時雙方對婚姻的滿意度降斬桃花到了最低點，是發生婚外情的最危險期。專家建議，夫妻要學會適應婚姻的平淡，理性看待婚姻的平淡，同時要積極創造機會重找舊日的激情，千萬不要相互指責。寬容與理解是這個時期夫妻間最寶貴的東西。

　　人到中年

　　此時，妻子進入感情挽回更年期，變得煩躁不安，丈夫精力也有所下降，這都在無形中影響著婚姻質量。此時，如果不能面對身體上的變化和性愛問題，愛人很可能從其他異性那裏尋找新的激情。因此，關心對方的身體變化，談談你們的性愛問題，能幫助度過危險期。

鋼琴調音-鋼琴二重奏的教學形式和方法

　　隨著近幾年來我國高考藝術類生二手鋼琴源的不斷增多，音樂專業的學生人數鋼琴收購也在逐年增加，傳統“一對一”的教學方式早已滿足不了正常的教學需要，于是出現了“一對二”、“一對四”以及集體課的教學形式，這些都爲練習鋼琴二重奏創造了有力的條件，不僅可以師生合作，還可以是生生合作。這些合鋼琴買賣作形式的優勢在于教師能夠整體上把握學生的合奏，並及時解決兩人在合作中的問題。這兩種教學形式可獨立使用，也鋼琴調音可根據具體情況交替使用或同時在一堂課中進行。除此之外，還可以用舉辦音樂會的形式，給學生藝術實踐的機會，可以使學鋼琴維修生充滿自信的站在舞台上，對學生戰勝舞台恐懼也有極大的幫助。

　　由于可以共同參與教與學，教學方法也就更加多樣。它根據具體的教學任務、教學內容和不同的教學對象加以選擇，是比較靈活多變的，但必須是有的放矢上的科學的訓練。它的教學除了有著一些和鋼琴獨奏教學共同的原則和方法之外，還有一些自己獨特的訓練要求，如：淡化自我，加強合作等。正是這些要求使二重奏教學既是一門獨立的藝術，又是輔助和促進鋼琴獨奏教學的有力臂膀。

　　通過以上論述，我們可以證明，鋼琴二重奏這種形式既多方面提高了學生素質、培養鍛煉了學生的綜合能力，又促進了教學交流，提高了教學質量，對促進教學改革具有積極的意義。希望越來越多的鋼琴教育者關注與此，並能在教學中貫徹這一思想，進一步提高教學水平，爲推動我國鋼琴教育事業的向前發展貢獻自己中古鋼琴的力量。

癌症飲食-11種常見食物是“天然防癌藥”

　　飲食不當可以致癌，但吃對食物增強免疫力也可以防癌。下面我們針對飲食爲大家推薦據證實有防癌作用的果蔬。 梨

　　能生津、潤燥、清熱、化痰。古代醫家多用之于食道癌、贲門癌和胃癌。如《滇南本草》雲：“治胃中痞塊食積。”《本草求原》也曾介紹：“治學業衰少，漸成噎嗝；梨汁同人乳、蔗汁、蘆根汁、童便、竹瀝服之。”《聖濟總錄》中還有一便方：“治反胃轉食，藥物不下；大雪梨1個，以丁香15粒刺入梨內，濕紙包四五重，煨熟食之。”由于裏所含的胡蘿蔔素、維生素B2、維生素C等都具有一定的防癌抗癌作用，所以梨還適宜鼻咽癌、喉癌、肺癌患者服食。

　　研究人員對吸煙者進行了試驗，讓他們在4天內連續每天吃750克梨，並測定吃梨前後尿液中多環芳香烴的代謝産物1-羟基芘含量。結果發現，吸煙6小時後吃梨，人體血液內1-羟基芘會經尿液大量排出；如果不吃梨，1-羟基芘排出很少。而加熱的梨汁含有大量的抗癌物質多酚，給注射過致癌物質的小白鼠喝這樣的梨汁，白鼠尿液中就能排出大量的1-羟基芘毒素，從而有效預殺死癌細胞防癌症。尤其是在吃過煎烤食品、快餐類食品後吃一個梨，是一種健康的生活方式。

　　也就是說，飯後吃個梨或喝杯熱梨汁，積存在人體內的致癌物質可以大量排出。調查結果顯示，吸煙或者吃烤肉等在體內聚集的強致癌物質多環芳香烴，在吃梨後會顯著降低，特別是喝了加熱過的梨汁。

　　猕猴桃

　　含豐富的維生素，尤其是維生素C的含量之高是橘子的4-12倍，是蘋果的30倍、葡萄的60倍。通過近年的研究證實，猕猴桃中含有一種具有阻斷人體內治癌的“亞硝胺”生成的活性物質，因而具有良好的抗癌作用。

　　動物實驗還顯示出其對黑素瘤、皮膚癌等多種腫瘤誘變的抑制作用。最近，研究者又從猕猴桃中提取出能降低人白血病細胞活性，誘導白血病細胞凋亡的物質，再一次顯示了猕猴桃獨特的抗腫瘤活性。

　　山楂

　　能活血化瘀、化滯消積、開胃消食，同時還含有豐富的維生素C。中醫認爲，癌瘤爲實性腫塊，往往具有氣滯血瘀征象，由于山楂能活血化淤、善消肉積，又能抑制癌細胞的生長，所以適宜多種癌瘤患者的治療。尤其是對消化道和婦女生殖系統惡性腫瘤患者兼有食欲不振化療飲食時更爲適宜。

　　杏

　　適宜多種癌症患者食用。據研究，杏是維生素B17含量最豐富的果品，而維生素B17是極爲有效的抗癌物質，對癌細胞具有殺滅作用。

　　香蕉

　　性寒、味甘，能清熱、通便，對大腸癌患者尤爲適宜。據現代醫學研究，香蕉含有豐富的微量元素鎂，而鎂有預防癌症的作用。1986年，中國醫學科學院腫瘤研究所發現防癌飲食，香蕉的提取液對三種致癌物——黃曲黴素B1，4-硝基喹啉-N-氧化物，苯丙(a)芘，都有明顯的抑制癌的作用。

　　橘子

　　凡芳香科柑橘屬的一類水果，諸如柑子、橘子、柚子、橙、檸檬、金橘等等，都含有豐富的維生素C。維生素C是一種防癌的屏障，可以阻止強致癌物亞硝胺的形成，尤其適宜食道癌、胃癌、肺癌、喉癌患者食用。

　　紅棗

　　能補脾胃、益氣血，還含有豐富的維生素B、C、P及胡蘿蔔素等，尤其是維生素C、P的含量特別多，均居百果之冠。國外學者分析出大棗中含有一組三萜類化合物，爲抗癌的有效成分；也有研究認爲，大棗中含有豐富的環磷酸腺苷，具有抗癌作用。所以，大棗又是一種抗癌果品。在民間，不少腫瘤患者手術、放療或化療後，常食大棗粥，或用黃芪煨大棗，每日用大棗10顆、生癌症飲食黃芪30克，共煨煮。這對提高免疫功能，增強體質，預防腫瘤的複發、轉移均有裨益。

　　草莓

　　適宜鼻咽癌、扁桃體癌、喉癌、肺癌患者以及這些癌症患者在放療期間食用，可以收到生津止渴、潤肺止咳、利咽潤喉的效果，對緩解放療反應、減輕病症、幫助康複也有益處。據《商業周刊》報道，美國俄亥俄醫學院病理學家加裏。斯托納和農業研究所植物遺傳學家約翰。馬斯在研究中發現，草莓中所含的鞣華酸能保護人體組織不受致癌物的傷害，從而對防治癌症有利。

　　無花果

　　能消腫解毒，適宜大腸癌、食道癌、膀胱癌、胃癌、肺癌、肝癌、乳腺癌、白血病、淋巴肉瘤等多種癌症患者食用，是一種廣譜抗癌果品。據現代藥理研究表明，無花果的確有良好的抗癌功效。：幹果的水提取物有抗艾氏肉瘤的作用。從未成熟的果實中所得到的乳汁能抑制大鼠移植性肉瘤、小鼠自發性乳癌，致使腫瘤壞死；又能延緩移植性腺癌、骨髓性白血病、淋巴肉瘤之發展，使其退化。

　　菱角

　　據1967年日本《醫學中央雜志多醣體》報道：發現菱角對抑制癌細胞的變性及組織增生均有效果，在以腹水肝癌AH-13及艾氏腹水癌作體內抗癌的篩選試驗中，發現菱角有一定的抗癌作用。可用菱角同粳米煮粥食用，也可用菱角加薏苡仁一同煮粥，適宜食道癌、胃癌、直腸癌、幽門癌、宮頸癌、乳腺癌患者經常食用。

　　百合

　　具有良好的營養滋補功能，還含有一種特殊的有效成分——秋水仙堿，具有較好的抗腫瘤效果，對多種癌症有效。適宜肺癌、鼻咽癌、皮膚癌、惡性淋巴瘤等患者食用。同時也適宜這些癌症患者經放射治療後出現體虛乏力、幹咳少痰或咯血、心煩口幹、體有低燒、心悸失眠時服食，可以收到止咳、止血、安神、增強體質、抑制腫瘤細胞的生長、緩解放療反應的效果。也可以制成百合粥，或爲百合羹，或煎百合湯均爲適宜。

　　溫馨提示

　　雖然水果的抗癌作用明顯，但在食用時，仍然要根據個人的特點進行選擇和適當搭配。經常有人因爲生吃草莓過量而引起胃腸功能紊亂。另外，患尿路結石、腎功能不好的病人不宜多吃草莓，因爲它含草酸鈣較多，過食會加重病情。

　　而且，吃水果的最佳時間是飯前1小時。水果屬生食，飯前吃水果等于吃生食後再進熟食，體內白細胞就不會增多，有利于保護人體免疫系統。

防火漆-防火塗料與防火板分別具有哪些的特點

目前市面上，隧道防火保護防火漆用的比較多的是防火塗料與防火保溫板，在實際使用過程中，各自有哪些特點呢，現簡單介紹：

從含水率方面來看，用膠水做界面劑固定，塗附著在管片上，無任何空隙，最終的含水量比管片的含水量高。而防火板在施工過程中，用不鏽鋼釘固定，與管片之間有空氣空隙，板材有著表層塑封，水分不易浸入板內，含水量較低的。

隧道防火保護最重要的就是産品的防火性能。就防火塗料而言，受火時，分子結構含水量高，産生熱氣狼，出現爆裂，結構上材料密度低較松散，抗火顯然能力差，因無支撐點而脫落呢。而氧化鎂耐火性能好，板內含有質纖維受火碳化後形成空隙，結構不會爆裂，燃燒時，板與板，板與管片之間有間隙，熱氣從間隙散開，再加上有多層的玻纖布做支撐，板上有平肩大頭螺絲做支撐，不易脫落的。因而防火塗料，使用壽命只在五到十年，維修率較高，防火保溫板使用壽命可以達25年，維修率較低的。

行車産生分壓頂部風道影響，塗料密度松散，風道內有負壓時，表層結構長時間受風壓侵襲，久而久之防火塗料被破壞的，由于風道內有著粗糙塗料層作爲內壁，風阻系數增大。防火保溫板密度高，強度好，表層光滑，是作風道的最佳材料哦。

對各自的施工環境要求：塗料施工時，環境相對濕度要低于70%，環境濕度大于5%，通風良好，無此條件施工質量會影響水泥凝固質量，最常見的現象是表面發黴。防火板施工對溫度，濕度，通風無特殊要求的。

雲端視訊-淺析集成化視訊會議平台優勢

隨著通信技術的發展，視雲端視訊頻會議得到了廣泛的應用，這種便捷方便的會議模式涉及到了社會的各行各業。除了滿足我們日常的開會討論需求之外，越來越多的行業客戶在日常應用中迫切的想將監控系統完美的融合到視頻會議系統中來，可以更好的在會議過程中，隨時調入各種監控信號，方便讓領導更好的對一些突發事件，緊急事件快速的做一些討論和決策，第一時間做好應急指揮。與此同時安防行業在廣大專業領域、商用和民用市場的日漸成熟，也在廣泛的開展行業化解決方案的研究。于是乎，隨著用戶單位需求的不斷升級，他們迫切希望能將視頻會議、視頻監控和應急指揮集成整合到一個平台上，實現溝通協調、資源調動、視頻監控、應急處理等方面的綜合應用。

集成化視訊會議平台優勢

隨著時代的發展，網絡與計算機應用已經遍布全球，爲軟件視頻會議的發展提供成熟的發展環境。而軟件視頻會議技術發展的成熟，現代視頻會議音頻采用GIPS技術，視頻采用H。264編碼，雲端會議室文檔寫作采用XML（面向未來的多媒體交換技術）實現，使得軟件視頻會議相對硬件視頻會議而言具有不可替代的優勢。爲此，集成視頻監控和應急指揮的視訊平台是利用專網、互聯網和無線通訊以及先進的信息技術和設備，下聯各個分支機構的視頻會議、視頻監控和應急指揮，實現全局視頻監控、項目指揮調度、日常視頻會議、人員培訓、協同辦公、聯合審計等功能。據此，我們在研發中極爲肯定集成性對于視訊平台的重要性，安尼數字統一視訊平台的結構和技術特點表現爲：

單一平台、高度整合

安尼數字會議監控一體化平台提供了高穩定和高質量的音視頻，同時具有強大的數據互動能力，電腦中的所有文檔均可遠程與其他參與會者共享討論，甚至標注修改，實現全互動的遠程協作和會議，並能對監控視頻進行動態標注，對于實現高效的指揮調度非常的切合。

網絡視頻，異地協同

全IP應用，只要有網絡的地方，無論海角，都可以一目了然；

先進的音視頻編碼技術，圖像經壓縮處理後占用碼流極小，克服複雜惡劣的網絡狀況，並實現清晰流暢傳輸；

我們理解的集成化視訊會議是統一視訊的概念，即統一平台、統一通信、統一指揮、統一調度。其實通訊的目的是爲了解決異地間信息的傳遞，相比較傳統的電話、傳真、郵件等，網絡視頻通訊技術的誕生真正做到了“如臨其境”，具有更形象、更生動的特點，其傳輸的內容也因此更爲豐富、更直觀、更快捷，從而開創了無障礙溝通新時代。

其實，現在雲計算的技術已經進入到視頻會議行業，這技術對于視訊監控一體化平台的兼容性和擴展性要求更甚，以後探索的路，還很漫長。

公母螺絲-控制鉚螺母螺栓預緊力

擰緊力與螺栓預緊力呈線性關系在，拉帽控制了擰緊力矩的大小，就可以通過實驗或理論計算的方法得到預緊力值。

下面我們來看以下關于控制螺絲預緊力的方盲孔螺母法:

方法1、通過擰緊力矩控制預緊力
控制了擰緊力矩的大小，就可以通過實驗或理論計算的方法得到預緊力值。但在實際中，由于鉚螺母受摩擦系數和幾何公母螺絲參數偏差的影響，在一定的擰緊力矩下，預緊力變化比較大，故通過擰緊力矩來控制螺栓預緊力的精度不高，其誤差約爲±25%，最大可達±40%一般來說，控制區擰緊力矩精度較高的工具是測力矩扳手和限力扳手。

方法2、通過鉚螺母轉角控制預緊力

根據需要的預緊力計算出鉚螺母轉角擰緊時量出鉚螺母轉角就可以達到控制預緊力的目的。測量鉚螺母轉角最簡單的方法是刻一條零線，按魯母轉過幾方的數量來測量鉚螺母角，鉚螺母轉角的測量精度可控制在10°-15°內。

方法3、通過螺栓伸長量控制預緊力

由于螺栓的伸長量只和螺栓的應力有關，可以排除摩擦系數、接觸變形、被連接件變形等可變因素的影響。所以，通過通過螺栓伸長量控制預緊力可以獲得很高的精度，此種方法被廣泛應用于重要場合螺栓連接的預緊力控制。

方法4、通過液壓拉伸器控制預緊力

使用液壓拉伸器給螺栓施加拉緊力，使螺栓伸長，然後旋合鉚螺母，待卸下載荷，由于螺栓收縮就可在連接中産生和拉力相等的預緊力。此種方法可以提高預緊力的控制精度。液壓拉伸器給螺栓施加預拉釘緊力時沒有摩擦力，故該方法適用于任何尺寸的螺栓冷鍛件，而且可以給一組螺栓同時施加預緊力，均勻壓緊鉚螺母和墊片，不致出現傾斜而影響預緊力的精確控制。

方法5、利用轉角控制預緊力

利用擰緊力矩與轉角的關系控制預緊力就是給螺栓施以一定的力矩，然後使鉚螺母轉過一定的角度，檢查最後的力矩與轉角是否滿足應有關系，以避鉚釘免預緊不足或預緊過度。

實木家具-實木家具開裂的原因

　　現在的人們買家具都喜歡買實木戶外家具的，這是因爲實木家具不僅有一定的收藏價值，而且更急環保，非常耐用、保存了原木的特質，但是有些用戶卻反映有些實木家具裂來了，這是什麽原因呢?難道是因爲質量問題?

　　很多朋友認爲如果實木家具開裂，那這實木一定是假的。其實不然，即使是真的實木家具，開裂也是在所難免的。就連價值連城的紫檀家具，在故宮展出時也會有開裂現象，同樣需要修複。

　　理由1：實木含水率問題

　　實木家具的含水率沒有控制好，將會出現開裂、變形等質量問題。家具在生産完畢之後，木材的含水率和幹燥應力決定了家具的造型和材質不會再發生改變。因此控制好實木家具的含水率變得相當重要，平衡後的含水率不會因爲陽光照射、過冷、過熱等環境因素發生開裂變形。

　　理由2：天氣所致

　　家具的含水率要求比實際空氣平均含水率低一至二個百分點。由于地理位置的差異，我國的氣柚木家具候天氣也不盡相同，因此對實木家具的含水率要求也不同。比如北京年平均含水率爲11。4%，所以實木家具的含水率應控制在10。4%或者9。4%；南方空氣平均含水率爲14%，則要求12%至13%。所以，一些南方的實木家具運送到北方之後，會有開裂的情況産生。

　　理由3：使用不當

　　一些朋友不好好保養名貴的實木家具，將它放置在臥室靠窗的位置，讓“寶貝”忍受陽光暴曬，或者用過于濕潤的毛巾擦拭灰塵，隨意挪動家具，導致家具框架受損等。這些都會影響家具的耐用度。

　　理由4：運輸受損

　　家具在運輸途中，難免會有磕磕碰碰，外加氣候的原因，實木家具運輸更是難上加難。雖然實木家具比起其他材料的家具，會較爲“堅挺”，但是不好好保養，也難于幸免。

　　再名貴的東西如果平時不注意保養也會破舊，所以在日常生活中我們要注意對實木家具的保養和維護。

防水密封圈-正確安裝柔性防水套管密封圈的6個方法

(1}檢查柔性防水套管、管件和橡橡膠迫緊零件膠密封圈的質量，清理承口和插口的橡膠製品汙物，然後將膠圈安裝在承口凹槽內，不得扭曲，異形膠圈應安裝正確，不得裝反。

(2)管端插人長度應留出溫差産生的伸縮量，其值應按施工時的閉合溫差計算確定，施工中可按表I一29的數值采用。

(3)插人深度確定後，應在管端畫出插人深度標線。

(4}在膠圈上和插口插人部分塗潤滑劑。潤滑劑必須無毒、無臭，且不會滋牛細菌般爲肥皂液或洗滌劑，嚴禁用黃油、對柔性防水套管和橡膠圈無任何O型環損害作用(一機油及矽橡膠墊圈其他油類作潤滑劑)。

(5)將插口插人承口，對准軸線，用緊線器等專用拉力工具均勻用力一次插人至標。當插人困難防水密封圈時，檢查橡膠圈是否放置到位。

（6）用塞尺順接口間隙沿管圓周檢查膠圈位置是否正確。

培林-軸承零件熱處理有哪些不足

從軸承零件粗糙口上可觀察到淬火後培林的顯微組織過熱。

組合滾針軸承是由一個向心滾針軸承和一個推力軸承組合而成，因此能夠承受徑向和軸向負荷。組合滾針軸承在徑向空間受到限制時，能爲軸承配置定位。它們特別適合于其它類型的定位軸承占據太多空間或軸向負荷很大、轉速很高或對僅僅推力墊圈潤滑不足的應用場合。

但要確切判斷其過熱的程度必須觀察顯微組織。若在GCr15鋼的淬火組織中出現粗針狀馬氏體，則爲淬火過熱組織。形成原因可能是淬火加熱溫度過高或加熱保溫時間太長造成的全面過熱；也可能是因原始組織帶狀碳化物嚴重，在兩帶之間的低碳區形成局部馬氏體針狀粗大，造成的局部過熱。過熱組織中殘留奧氏體增多，尺寸穩定性下降。由于淬火組織過熱，鋼的晶體粗大，會導致零件的韌性下降，抗沖擊性能降低，軸承的壽命也降低。過熱嚴重甚至會造成淬火裂紋。

沖壓軸承與鑄件、鍛件相比，具有薄、勻、輕、強的特點。沖壓可制出其他方法難于制造的帶有加強筋、肋、起伏或翻邊的工件，以提高其剛性。由于采用精密模具，工件精度可達微米級，且重複精度高、規格一致，可以沖壓出孔窩、凸台等。

沖壓軸承一般不再經切削加工，或僅需要少量的切削加工。熱沖壓件精度和表面狀態低于冷沖壓件，但仍優于鑄件、鍛件，切削加工量少。

欠熱

淬火溫度偏低或冷卻不良則會在顯微組織中産生超過標准規定的托氏體組織，稱爲欠熱組織，它使硬度下降，耐磨性急劇降低，影響軸承壽命。

淬火裂紋

軸承零件在淬火冷卻過程中因內應力所形成的裂紋稱淬火裂紋。造成這種裂紋的陶瓷軸承原因有：由于淬火加熱溫度過高或冷卻太急，熱應力和金屬質量體積變化時的組織應力大于鋼材的抗斷裂強度；工作表面的原有缺陷（如表面微細裂紋或劃痕）或是鋼材內部缺陷（如夾渣、嚴重的非金屬夾雜物、白點、縮孔殘余等）在淬火時形成應力集中；嚴重的表面脫碳和碳化物偏析；零件淬火後回火不足或未及時回火；前面工序造成的冷沖應力過大、鍛造折疊、深的車削刀痕、油溝尖銳棱角等。總之，造成淬火裂紋的原因可能是上述因素的一種或多種，內應力的存在是形成淬火裂紋的主要原因。淬火裂紋深而細長，斷口平直，破斷面無氧化色。它在軸承套圈上往往是縱向的平直裂紋或環形開裂；在軸承鋼球上的形狀有S形、T形或環型。淬火裂紋的組織特征是裂紋兩側無脫碳現象，明顯區別與鍛造裂紋和材料裂紋。

熱處理變形

軸承零件在熱處理時，存在有熱應力和組織應力，這種內應力能相互疊加或部分抵消，是複雜多變的，因爲它能隨著加熱溫度、加熱速度、冷卻方式、冷卻速度、零件形狀和大小的變化而變化，所以熱處理變形是難免的。認識和掌握它的變化規律可以使軸承零件的變形（如套圈的橢圓、尺寸漲大等）置于可控的範圍，有利于生産的進行。當然在熱處理過程中的機械碰撞也會使零件産生變形，但這種變形是可以用改進操作加以減少和避免的。

表面脫碳

軸承零件塑膠軸承在熱處理過程中，如果是在氧化性介質中加熱，表面會發生氧化作用使零件表面碳的質量分數減少，造成表面脫碳。表面脫碳層的深度超過最後加工的留量就會使零件報廢。表面脫碳層深度的測定在金相檢驗中可用金相法和顯微硬度法。以表面層顯微硬度分布曲線測量法爲准，可做仲裁判據。

軟點

由于加熱不足，冷卻不良，淬火操作不當等原因造成的軸承零件表面局部硬度不夠的現象稱爲淬火軟點。它象表面脫碳一樣可以造成表面耐磨性和疲勞強度的嚴重下降。

焊接護具-電焊機選購常識

電焊機的用途很廣泛。不管電離子焊接機是大的造船企業、工礦企業和各種建築企業電焊機是不可缺少的工具。電焊機是用于材料焊接的，在使用時是帶電的，尤其是一些小的施工單位爲節省成本購買便宜的電焊機，在施工現場惡劣的環境下使用很容易引起觸電、著火、脫焊的現象發生，會危及人身安全氬焊機和財産安全。因爲焊接質量不好也會造成“豆腐CO2焊機渣”工程。所以在選購電焊機時要注意的幾點要求：

　　一、在選購電焊機産品時，要到正規的生産企業或大商場去選購，並且要選購市場占有率較高的品牌名優産品。千萬不要貪圖便宜到小商店去購買，那裏焊接護具的電焊機質量無法達到保證。

　　二、選購時，檢查産品上半自動電焊機的銘牌是否有生産廠家的名稱、生産地址、規格型號、焊接電流調節範圍、負載持續率及輸入電壓電流等一些內容，隨後根據工作需要來確引擎電焊機定自己要購買的電焊機。

　　三、購買時可以要求經銷商提供産品質量檢驗報告或合格證。因電焊機産品是國家強制性認證産品，所以購買時TIG焊機一定要確認該産品是否通過“3C”認證。

　　四、購買時一定要檢查該産品是否有接地螺釘，接地螺釘連接處應無油漆接地良點焊機好。機芯是否清潔絕緣是否有損壞，以保證使用安全，必要時也可檢測一下。

　　五、購買前可以通電檢查一下面板上的開關的操作，轉換以及安裝情況，電源指示燈的亮滅，風扇是否正常，電源部分是否有異常的振動及蜂鳴聲，是否有異味，外觀上是否有變色等發熱現象，以保證電焊機的質量，充分發揮電焊機的性能。

　　六、如要購買氣體保護焊機的，在購買前還要檢查配件是否齊全，送絲機是否有油汙，轉動是否平穩，連接電纜是否匹配外表絕緣是否有損壞，以保證電弧的穩定性。

分泌物變多-性感女人必備 私密處保養妳應該知道的七件事

女人都愛保養，尤其隨著年紀日漸增分泌物變多長，無論是臉上還是身體的保養都砸下重本，但有個地方你可能常忽略，那就是女人最特別擁有的私密處！性愛生活調查報告，有27%的台灣女性表示，在性行為中最在意自己私處的味道，相信大家都很愛自己的身體，偶爾身體狀況不太好，而有些異味，讓性愛進行或甚至走在路上時有點小尷尬，其實女人都該擁有健康私密處，而這些小知識你應該知道。

一、用清水清潔最乾淨

隨著私密處清潔產品引進台灣，大家終於開始稍微重視私密部位的保養，但其實清水，就能達到最好的清潔效果，如果使用太多肥皂或沐浴乳反而會破壞正常PH值（正常應該是3。8~4。6的弱酸性），使細菌滋生的機率增加，如果你不用沐浴乳不安心，記得確保沒有任何清潔劑殘留。也要慎選私密處清潔液，我們都想要有好聞的味道，但過多香精添加容易傷害分泌物有異味皮膚。

二、用最溫柔的觸感對待它

路邊攤不到一百元的內褲固然可愛，但一分錢一分貨，純棉質感才能夠呵護妳最細嫩的皮膚，除了內褲外，最常接觸的就是每個月都用得到的衛生棉，無論是棉條還是護墊，都建議使用三小時就要換新，畢竟細菌我們看不到，勤更換也不容易有異味，醫生也建議，非必要不要使用護墊，

三、做愛後上個廁所最乾淨

一般人可能都知道做愛前該洗乾淨，做愛過後也該沖澡才能有效清潔，但在清潔前，強烈建議，你得先小便，因為在歡愛時，細菌可能會進入尿道，而小便可以有效讓這些細菌能夠離開體內，也免得到尿道或是膀胱炎。除了細菌外，若是精液殘留會造成酸鹼不平衡，容易使細菌孳生，如果你不愛用保險套，那就完事後加強清潔吧！

四、過緊的褲子會讓陰道有壓力

貼身內搭或牛仔褲有型又好看，但太過緊貼肌膚會讓私密處無法呼吸，空氣無法流通外，皮膚也會非常缺水，進而容易散發異味。穿上較為寬鬆的褲子讓美腿透透氣吧！如果因為淋雨或是沾染的經血而弄濕，最好儘快更換褲子，去除水氣，讓細菌沒有溫床可以增生。

五、定期除毛，讓陰毛呼吸

許多的朋友從來沒有修剪過陰毛，對他們來說，自己拿剃刀修剪是非常害羞的事情，但親愛的女人，就和頭髮一樣，陰毛也需要藉由修剪來汰舊換新，才能不藏汙納垢和引發異味，妳可以沿著比基尼線修剪，但不需要全部剃光，讓它呈現舒服又能保護的最佳狀態。

六、吃大蒜和水果，妹妹味道自然香

快丟掉那些香精沐浴乳或是香氣潔膚巾，讓陰道味道好聞，靠水果就能做到！多吃小紅莓、鳳梨、草莓這類的水果，不只讓妳的陰道能有自然的氣味，也能夠幫助代謝身體毒素，一舉兩得。另一個有益食物就是大蒜，大蒜也許會帶來口臭但卻能給你一個氣味芬芳的健康陰道，它能有效殺死酵母，進一步達到預防酵母菌感染的作用，讓私密處保養私密處更健康。

七、陰道也要每天做運動

每週做運動能夠幫助女人維持完美體態，其實陰道也需要常常做運動！之前紅教過的凱格爾運動就能派上用場，不只能讓陰道更健康，也能提升性生活的品質，建議女人每天做，並且逐漸增加次數和長度。如果不知道做得對不對，很推薦利用小工具輔助，像是每天練習陰道啞鈴，久了你會感受到不可思議的成效。

奇亞籽減肥-瘦身 方法有哪些 兩大減肥誤區大曝光

有效的減肥，不僅要能瘦，還得保得排便順暢住減肥成果，還得健康，不會對身體造成損傷，才是減肥的意義所在。快速有效地瘦身方法有哪些呢？下面給你一一介紹。

一、飲食減肥食譜

1、清蒸羊肉
羊肉是冬季進補的最佳食物。羊肉性溫熱，補氣滋陰。羊肉可以暖身，同時羊肉含有一種類似“燃脂素”的營養成分，它是轉運脂肪酸進入線粒體的載體。而脂肪酸必須在線粒體內才可以燃燒。因此多吃羊肉有助于燃燒脂肪。

清蒸羊肉的做法：

1、瘦羊肉750克切成3大塊，洗幹淨後減肥餐放入沸水鍋裏煮一下，然後撈出洗幹淨減肥瘦身。
2、羊肉再次放入沸水中，加入蔥、姜、大茴香、花椒，煮熟。
3、將羊肉撈出，放涼，去除浮沫，切成薄片，然後點入碗底在上面放入少量蔥、姜，加入雞湯上籠蒸15分奇亞籽減肥鍾。
4、去除蔥、姜、湯瀝入鍋裏，肉扣入湯盤，再將纖維減重原湯加適量精鹽和味精調勻，加入麻油即可食用。

2、苦瓜炒蛋
苦瓜具有減肥的作用。涼瓜含有清脂素，當進入減肥代餐人體後，清脂素會作用在小腸上。通過改變腸細胞網孔，阻止脂肪、多糖等高熱量大分子物質的吸收。從而加速體內小去水腫分子營養的吸收，但又不參與人體代謝。

苦瓜炒蛋的做法：

1、將苦瓜切成薄片，用鹽揉抓片刻，然後用手擠掉苦瓜水。
2、鍋裏加清除宿便入是少量的油，倒入一點點料酒贊一下。然後倒入苦瓜炒一下，加入一點糖，炒到八成熟的時候裝碟。
3、雞蛋打成雞蛋液，鍋裏加入油，略炒雞蛋。然後加入苦瓜，和雞蛋一起翻炒幾下即可。

Rubber O-Ring-Vivitar Digital Cameras

There is a huge Rubber Gasketvariety of digital cameras to choose fromRubber Parts。 Vivitar is one of the more respected and well-known names。 The Vivitar digital camera range of sporty and versatile cameras suit a wide range of people。 There are seventeen models in the Vivitar range: three DVR models， which have the functionality of both MP3 players and DVRs。

Vivitar made a big splash when the brand was first introduced to the celebrity mainstream。 Vivitar´s line of cameras were used by some of the entertainers at the MTV Music Awards and the Sundance FilmCustom Mold Rubber Parts Festival。 Although this has helped， they are not the only things that have stood Vivitar in such high stead。 The range of affordable and good looking cameras make them a good choice for anyone looking for a new digital camera。

Underwater Fantasy

Although for most consumers， the idea of having a waterproof camera might seem a little over the top and would at the most bring up images of being protected from a heavy downpour， rather than fully-submerged。 The ViviCam 6200w features a rubber seal and helpsRubber Seal to keep it waterproof at up to 30 feet below water， making it ideal for outdoor activities， and for heavy showers。

A two inch monitor gives plenty of space to view the up to 6。0 megapixel images， rather than through the viewfinder。 There is also a built-in flash， support for more memory by buying another memory card with higher capacity。 There is also a range of picture editing software to allow standard pictures to be given that little extra something and to do standard edits like removing red-eye。

Vivitar DVR-530

The are three cameras in the DVR range， but the DVR-530 offers a little something extra。 The standard stills camera options are all there， but included are the ability to take movies， and to listen to MP3s。 The 2。5 inch screen allows viewing of pictures that can have up to a 5。0 megapixel resolution。 For close-ups there is a standard 3x optical / 4x digital zoom。 The video recording capabilities don´t match those of traditional video cameras， but that shouldn´t bother most people。 With a large amount of video only be distributed and viewed online， there is often very little reason to have the super high quality when the final version is viewed on a computer screen。

Wide Range

The functional range of Vivitar cameras extends from 5。0 megapixels up to 10 megapixels。 The range follows budgetary considerations， and the top-end models will set you back a bundle。 The ability to change many of the features is one of the greatest assets of the upper range models。 These features are indispensable for the professional photographer。 Have a look at the whole rangeRubber O-Ring and you´ll be sure to find something suitable。

All in one computer-How Long Will My Flat Panel Tv Live?

A decent amount All in one computerof people worldwide have taken up possession of flat panel televisions。 One would almost think it was a newborn baby in these people´s possession with the care and attention these televisions receive over time。 Perhaps that´s because a plasma or LCD television can， indeed， set one back a few thousand dollars。

Other thanVideo wall the intense difference in your home theater quality， in some circles， one of these TV gems represents a kind of status symbol。 With that kind of financial investment this would warrant a special kind of maintenance and care。 Like with anything you take care of， it should give you a quality performance for years to come。 So， let´s take aBox PC look at the length of time one receives such performance from their flat panel TV。 In order to do this， we will be dissecting each type of high performance television。

Flat Panel Televisions:

Originally the word "lifespan" was used to prose this topic but that was wrong in a sense。 A television is measured as a "Half-Life"， the time before the television´s screen dims from one half of the original brightness。 Every television from Flat panels to CRTs loose brightness over time and this cannot be helped。

Should you， aspanel PC a prospective buyer or owner， worry about the lifespan of your television? Not really， but some people do commonly fear their extravagant televisions will burn out long before the classic yet reliable picture tube sets of yesteryear。

Consumer Reports， an independent nonprofit organization， published a report last year， which explains flat panel sets are just as reliable as CRT TVs in their first year。 Most won´t be fearful about long-term reliability because they would more than likely be looking for a new TV long before their flat panel fades to black。

The LCD Screen:

The winner in the debate between longevity of LCD and plasma televisions is the LCD。 The LCD panel alone holds a virtually limitless lifespan because of this the screen´s LCD light source。

The light bulb of a the LCD is what produces pictures， and just as with any other light bulb， the light will dim over a period of time after repeated use。 Hence both the bulb andsunlight readable the LCD screen life are equivalent to one another， the proposed life span ranges from 30，000 to 60，000 hours。 Some manufacturers estimate a larger sum of 80，000 hours。 Replacing these bulbs will easily increase your television´s lifespan。 Watching an average of about six hours a day will givedigital signage you just about 28 years before the LCD´s brightness begins to dim to half it´s original level。

The PlasmaFanless pc Television:

Plasma is somewhat inferior to it´s LCD counterpart in the case of a lifespan。 The common mistake is that a plasma television will last almost 10 years， this as stated already， is not true。

Plasma televisions use gases where the LCD uses bulbs for lighting。 Like anything else， plasma gases will decay overtime。 This process is a slow and gradual one with ranges from 20，000 to 30，000 hours along with the manufacturer estimation of 60touch screen monitor。000。 All of theseIP66 estimates are figured under optimal conditions。 Currently there is no form of replacement for plasma gases。 This makes the average six hour a day of televisionIndustrial pc equate to 14 years before the plasma´s brightness begins to fade to one half of the original level of brightness。

To put these life spans in terms of relative experience - the cathode ray tube or CRT televisions， which we have been most accustomed to， have one of the longest life spans of up toIndustrial monitor more than 80，000 hours。

sintered metal-Metal Stamping House

Stampings is thepowder metal process of cutting and forming metal alloys into specific forms especially for use as components for large machinery or structures。 Metal sheets can be molded into different pre-defined forms for use as food as regular pots and jars。 The most common alloys used in metal stamping steel zinc nickel aluminum and titanium。 Stampings is a very effective and productive means of production of many types of metal on a large scale。

In stamping metalpowder metal sheets are placed in a matrix or a press tool which is specially designed cavity that gives the preferred form of sheet metal。 Upper part of the matrix is connected to the press slide while the lower component connects to the press bed。 Specific component known as the blow pushes the sheet metal through the die thus performing the actual development of the operation。 After pressing metal coated with gold palladium nickel or tin to prevent corrosion。

Coverage also increases wear and solderable nature of the product。 Sometimes leaves are also pre-coated before the stamping process and then purify the product from excess stamping oils and films。 The product is then heat-treated to make it stronger because it is still in soft condition after stamping。 The product is then subjected to the process of deburring to remove sharp corners。 This is done with chemicals or abrasives。 Stampings also includes other processes such as metal-piercing cleaning shaping and drawing on the same machines。

Precision metal stamping is applicable to many industries like computers electronics electrical dental aerospace instrumentation military specs defense telecom and automotives。 There are many methods in precision metal stamping for producing stamped prototypes。 Blank creation is one such method。 Blank creation involves the creation of a flat state of the component。 The flat blank sheet is then used to make the parts features。 In blank creation there are many processes like nibbling chemical etching water jet cutting wire EDM punch and die。

Stamping presses have specific strength speed and accuracy to give a definite form to the metal。 There are two types of metal stamping presses: mechanical and hydraulic。 They are available in a wide range of power size stroke length and operating speed。

Stampings are gradually replacing other metal forming processes like casting forging fabrication and processing。 One reason for this is the very low cost of metal stamping。 Dies forsintered metal stamping cost less than those used in the forging and casting。 In addition the metals used in metal stamping can be harder than those used in other processes resulting in a final product stronger。 The cost of secondary processes like cleaning and plating is also significantly reduced。

In addition there are certain foods that should be done only through a metal stamping: Base weights brackets balance clamps brake flanges conveyer flights bushing seats engine bases flywheel shrouds and friction plates。 There are also various types of stamping including: Deep drawn stamping electronic stamping embossing Fourslide medical stamping embossing and short-term progressive stamping。 The most commonly used type is a progressive drawingsintered metal Die where the sheet metal passes through a series of stamps and stamping dies made all at once thereby significantly reducing the time it takes。
