Plastic bearing-Plain Bearing

A plain bearing Plastic bearingis a simple mechanism consisting of two sliding components。 This lightweight, compact and inexpensive bearing is widely used in many types of equipment and is sometimes referred to as a Babbitt, bushing, or journal bearing。 A plain bearing can be used for three basic types of motion: linear, thrust, and journal。 The basic types of plain bearings are bushing, integral or two-piece。 The bearings may be composed of many types of materials。

Plain bearings used for linear motion may consist of either a round bearing and shaft assembly or two corresponding surfaces that slide against each other。 Thrust motion plain bearings allow rotation to take place between two parts while supporting an axial load。 Journal motion bearings typically consist of a rotating shaft inside of a stationary bearing。 A journal motion is the most common type of motion in which a plain bearing is utilized。

A bushingslide bearing type bearing is a separate piece that is fitted inside of a housing to provide a replaceable bearing surface。 Bushings are generally the most common type of plain bearing application。 An integral bearing is actually built into the piece of equipment for which it is being used。 Integral bearings typically consist of a machined hole bored directly into the piece of equipment with a steel shaft running through it。 Two-piece bearings are commonly utilized for large diameter applications such as crankshaft and connecting rod assemblies。
must be constructed of a durable material that provides low friction and is resistant to both heat and corrosion。 Plain bearings are typically composed of two separate components。 One bearing component is usually made of a soft material while the other is much harder。 In most applications, the soft bearing component is used to support the harder one。 A wide variety of materials are used to make the components of plain bearings。

Bronze is typically used in bushing type bearings in combination with a polished and hardened steel shaft。 The softer bronze bushing supports the shaft and can be easily replaced when it becomes worn。 A graphite and copper alloy is typically utilized for plain bearing applications in ovens and dryers。 The graphite material in the alloy acts as a dry lubricant for the bearing。 Cast iron generally provides a long-lasting material in combination with steel shafts in thrust motion bearing applications。

Babbitt metal is frequently used as a bore coating for integral type bearings to collect lubricant contaminants and prevent damage to the journal。 Solid plastic typically provides a durable bearing material that requires no lubricant。 Plastic polymer materials are also resistant to corrosion and generally maintenance free。 The hard ceramic material used in some plain bearings is usually able to grind sand and grit contaminants to a fine powder while providing continuously smooth operation。

變頻器-淺談高壓變頻器主要的技術優點


  1、高壓變頻器調速範圍爲0~變頻器100,如果電機和負載機械強度允許,電機也不過流的話,還可以使機械超速運行;而液力偶合器的調速範圍一般爲40~95,即高速段造成約5的速度損失,影響機組的出安川變頻器力;而液力偶合器最低一般只能到額定速度的40,有些情況下,不能滿足調速可程式控制器需要,有些時候影響節能效益的進一步發揮。

  2、高壓變頻器在整個調速範圍內都具有較高的效率(大于96);而液力偶合器在調速越低時效率越低,本身帶來不小的損耗,調速的節能效果大打折扣。

  3、高壓變頻器對電機及負載機械實現真正的軟啓動,徹底解決了啓動沖擊問題,如果工藝需要,電機可以在短時間內多次重複啓動;而液力偶合器不能解決電機啓動問題,電機仍然爲伺服馬達直接啓動,需要啓動裝置,啓動沖擊也大,並且不能頻繁啓動。

  4、用高壓變頻器對電機進行調速改造時,只需脫開原來的開關和電機的連接電纜,加入變頻器即可,不動電機和機械的連接關系減速馬達,不用改動任何基礎,也不存在場地限制問題;而用液力偶合器做調速改造,必須將液力偶合器串入電機和機械的連接軸中,需要移動和重新澆注設備基礎,有些地方空間也未必允許。

  5、用高壓變頻器對安川伺服馬達電機進行調速改造,一旦變頻器故障,電機還可以直接挂工頻電網運行,不會造成生産損失;而液力偶合器爲電機和機械的連接紐帶,一旦液力偶合器故障,負載機械將無法運轉,只能停機維修液力偶合器,造成停産損失。

  高壓變頻器是高科技設備,可靠性高,基本免維護;而液力偶合器是機械設備,本身包含油路、水路等多套系統,故障率高,維修工作量大,造成有效生産時間的縮短。

  6、高壓變頻器不會因爲電機速度的高低增加成本,而低速大容量的電機用液力偶合器調速,液力偶合器的成本將大大增加,有些時候甚至無法實現。

  7、對于一般的電機進行調速,采用高壓變頻器比采用液力偶合器的初期投資要大,但日後變頻器幾乎不需要什麽運行費用。而液力偶合器需要經常維護,包括養一個專門的維護班組、經常花錢換水換油等等,運行費用較高。

  8、高壓變頻器具有高度的智能化水平,調速精度高,還可以直接閉環運行,提高工廠的自動化水平,減少工作人員,改善工作環境,減少工作量;而液力偶合器調速精度較差,談不上自動控制,更沒法和計算機接口,還漏水漏油,現場也經常髒汙不堪,導致環境極差。

  總之,用戶如果有設備需要調速,從我們的觀點來看,如果資金不是特別緊缺,建議不要采用液力偶合器。

台中居家清潔-不同建材保養方法不同 家居清潔注意事項多

家居清潔是每個人日常生活的一項工綠建材作,但是很多人不清楚對于所有裝飾材料的清潔辦法,下面我們就介紹下相關知識。

1、牆壁、天花忌用力猛擦木板牆、彩色瓷磚與木天花板,清潔時可用濕布沾稀釋肥皂水輕抹,不可用力以免傷及表面。粉牆、壁紙牆,清潔時只需用雞毛帚由上至下撣去塵埃即可。不論是哪種牆壁,若是沾上汙垢時,千萬不可用力猛擦,否則會損壞牆壁。最好是用一杯酒精、一台中清潔公司小匙清潔劑混合後,以噴霧器噴在牆壁的汙垢處,再以熱毛巾覆蓋汙垢就能輕易去除了。

2、真皮沙發忌用熱水擦拭真皮沙發切忌用熱水擦拭,否則會因溫度過高而使皮質變形。可用濕布輕抹,如沾上油漬,可用釋稀肥皂水輕擦。

3、藤編家具忌用普通洗滌劑刷洗藤編家具用普通外牆清洗洗滌劑刷洗,會損傷藤條。最好使用鹽水擦洗,不僅能夠去汙,還可使藤條柔軟富有彈性。藤椅上的灰塵,可用毛頭軟的刷子自網眼裏由內向外拂去灰塵。如果汙迹太重,可用洗滌劑抹去,最後再幹擦一遍。若是白色的藤椅,最後還抹上一點醋,台中居家清潔使之與洗滌劑中和,以防變色。用刷子蘸上小蘇打水刷洗藤椅,也可以除掉頑垢。

4、清潔時忌行走路線雜亂正確方法是:由上至下,由裏而外,將清潔用具放在一只桶裏面,讓它隨時跟隨著你,以順時針方向打掃房間。將所需的清潔用具集中存放並保持已打掃過的房間幹淨整潔。

5、塑膠地板忌用水拖洗用水清潔刷洗塑膠地板會使清潔劑及水分和膠質起化學作用,造成地板面脫膠或跷起現象。如碰到水潑灑在塑膠地板上,應盡快將其弄幹。

中古機械回收-印尼要求英國收回廢金屬


  英國環境署日前證實,印尼要求貴金屬回收英國收回其出口到印尼的1800噸有害廢金屬。這批廢金屬今年1月底在印尼最大貨運港丹戎不碌港被查獲,同時被查獲的還有來自荷蘭的24箱廢金屬。

  ,海關人員在查驗這批標記爲無害廢金屬的貨物時,發現集裝箱有液體滲漏,抽查後發現集裝箱裏除廢金屬外,還有瀝青、沙土、塑料、廢舊電腦主板等。抽查官員稱,這簡直就是將垃圾直接丟進了集裝箱。印尼在2月底宣布,查獲的這批廢金屬中含有砷、鉛、鉻等高濃度有害物質,有悖于印尼多項法規。爲此,印尼政府要求英國和荷蘭收回這批有害廢金屬。

  這是近年來印尼海關查獲的最嚴重事件之一,反映了印尼這樣的發展中國家在處理來自發達國家的廢品時所面臨的困境。事實上,印尼環境廢五金回收保護法禁止進口危險有害廢品,印尼廢物處理法更是禁止進口任何種類電子零件回收的廢品。然而,出于經濟利益的考量,印尼貿易部下達法令,允許進口某些種類的廢品。

  此次事件發生後,印尼環保人士紛紛要求政府采取嚴厲的措施打擊廢品進口,不管廢品是否有害,都不應當進入印尼境內。然而,經濟處于快速發展期的印尼對原材料需求旺盛,不可能完全禁止廢品進口。以這次事件爲例,海關人員在查獲有害廢金屬後,擴大了對進口廢品的搜查,扣留了大量進電子零件回收口廢金屬。但由于海關抽查能力有限,造成大量廢金屬滯留港口,印尼當地的鋼鐵制造商開始抱怨原材料供應緊張,影響生産。據印尼鋼鐵工業協會稱,印尼國內的原材料供應無法滿足當地的工業廢五金回收生産需要,當地鋼鐵生産商每生産600萬噸鋼坯和鋼板就需要750萬噸廢金屬,而其中70%的廢金屬來自進口。如果印尼禁止進口廢金屬,將對當地的工業生産造成嚴重影響。

  目前,印尼已就此事對英國提起訴訟,並中古機械回收期望在3月底將這批廢金屬遣返英國。即使這批廢金屬能夠順利返還給英國,英國方面如何處理這批垃圾以及如何能保證不再運到其他國家都是疑問。

  發達國家向發展中國家出口垃圾並不是新鮮事,但如何平衡好兩方的利益卻是需要關注的問題。發達國家應該負起自己的責任。英國和荷蘭都是控制有害廢物越境轉移的《巴塞爾公約》締約國,更應該在廢品出口上加強監查力度,不能因爲處理程序複雜、成本高昂而放任有害垃圾流入他國。印尼在加大對進口廢品監管力度的同時,還應當對允許進口的廢品制定明確的標准。丹戎不碌港海關官員在接受本報采訪時說:“印尼只允許進口幹淨安全的廢金屬。”然而,對于“幹淨安全”,他也沒能給出一個明確的具體標准。

廢五金回收-廢金屬拆解業亟待綠色化


正午的陽光炙烤著大地,老林卻沒有塑膠回收休息,他經常要幫客人拉的廢五金回收貨,是從各種舊電機、舊電腦、舊線路板上拆下來的各種可以再利用的舊物資。

他習慣開著他那輛小型貨車,在溫峤鎮政府附近尋找生意。溫峤鎮是一個拆解業相對集中的地區,就在周邊的一些村落裏,比如桐山和橫路頭,就布滿了各種小型拆解場地和家庭下腳料回收作坊。

溫峤鎮的固廢拆解業興起于上個世紀80年代,近幾年來,該行業發展迅速,溫嶺市環保局汙控科科長潘雲晖告訴CBN,溫嶺市的拆解業,主要集中在澤國、新河、溫峤三鎮,有定點拆解企業,也就是有資質進行第六類第七類垃圾拆解的企業,共7家,年拆解量爲19。7萬噸。

此前,當地媒體報道說,溫峤鎮共有25個村384戶村民從事拆解行業。不過潘雲晖表示,對于家庭作坊式的拆解點到底有多少,很難搞得清楚。

長期存在固廢拆解現象,使得當地的環境嚴重惡化。報道稱,桐山村因爲汙染,那裏的地下水和山泉水已不能飲用了。固體廢物拆解還帶來了露天亂焚燒,産生的有毒有害煙塵和氣體,也使得澤國鎮新秋村一棵百年老樟樹汙染致死。

汙染的問題,相當長時間以來都困擾著台州的拆解業。但是對于台州來講,今後的經濟發展,無論如何也缺少不了拆解業。

把垃圾做成事業

台州的廢舊金屬綜合利用産業始于上世紀七十年代末期,以原路橋峰江鎮(現峰江街道)爲主,主要以拆解國內廢舊物資爲主,他們把全國各地廠礦等部門、單位裏報廢的舊機械、車床、汽車、電機等物資買回來拆解,有修好可再用的小機床、電機等,清洗、修理好供給當地民營小廠繼續使用;不可修理的,就整體拆解成鋼鐵、銅、鋁等金屬,供給當地民營工廠做原料。

這些廢金屬經拆解後彙集到市場,重新開始組合分配,比如一只舊變壓器解體後,機殼經焊廢銅回收接可造農用鐵殼船,散熱扁管拉圓後可做落地式電扇、木工鑽鋼管和防盜窗,矽廢電線回收鋼片是家用電器制品的材料,銅排用作沖制小商品,變壓器油改制潤滑油,大量的銅、鋁、鐵運送到冶煉廠回爐或經加工變成銅絲、鋁絲和其他産品。

1991年底,峰江已經擁有廢金屬銷售市場2個,個體拆解點200多個,從業者超過3000人,年拆解廢金屬材料10多萬噸,成交總額達到3。5億元。之後,峰江的廢金屬收購從國內延伸到國外,進口廢舊物資占到總拆解量的90%以上。

在拆解業興起的同時,台州的工業也正面臨著原材料緊缺的困局。數據顯示,當時台下腳料回收州工業每年大約需要鋼材12萬噸。而國家計劃配給的只有0。7萬噸,且計劃兌現率僅爲30%到40%,爲台州所需的2。3%。市場需求推動著台州固廢拆解業迅速發展。

此時,正在西北打工,直到1987年回來。回鄉後,就發現,他的老家已經是特殊金屬回收萬戶敲擊聲,每家每戶都在用錘子敲打破舊的機器,把機器拆開,把零部件一個個卸下,歸類,再賣掉。

在滿足了工業所需原材料的同時,拆解業在峰江也越做越大,並爲台州贏得了“中國再生金屬之都”的稱號。
