產(chǎn)品詳情
發(fā)射換能器利用壓電元件的逆壓電效應(yīng),而接收換能器則是利用壓電效應(yīng)。超聲波流量計(jì)換能器的壓電元件常做成圓形薄片,沿厚度振動(dòng)。薄片直徑超過厚度的1倍,以保證振動(dòng)的方向性。壓電元件材料多采用鋯鈦酸鉛。為固定壓電元件,使超聲波以合適的角度射入到流體中,需把元件故人聲楔中,構(gòu)成換能器整體(又稱探頭)。聲楔的材料不僅要求強(qiáng)度高、耐老化,而且要求超聲波經(jīng)聲楔后能量損失小即透射系數(shù)接近1。常用的聲楔材料是有機(jī)玻璃,因?yàn)樗该鳎梢杂^察到聲楔中壓電元件的組裝情況。1.1.2超薄壁不銹鋼塑料復(fù)合管超薄壁不銹鋼塑料復(fù)合管是一種外層超薄壁不銹鋼管,內(nèi)層塑料管和中間粘接劑復(fù)合而成的新型管材。其性能特點(diǎn):外層不銹鋼管管壁更薄,內(nèi)襯塑料管壁厚也減少,主材價(jià)格進(jìn)一步降低。表面不銹鋼把塑料管與外界隔絕,克服塑料易氧化老化之缺點(diǎn),又提高了塑料管阻燃性能與承壓強(qiáng)度。中間粘接劑約束了內(nèi)襯塑料管膨脹,管材線膨脹系數(shù)很小。既可使用不銹鋼粘結(jié)管件,又可采用的不銹鋼、銅等卡套式管件,連接方式多樣,安裝方便。

專家認(rèn)為,今后包裝機(jī)械市場(chǎng)發(fā)展將呈現(xiàn)以下特點(diǎn):首先,包裝機(jī)械技術(shù)含量日趨增加。其次,包裝機(jī)械市場(chǎng)日趨壟斷化。后,包裝機(jī)械零部件生產(chǎn)專業(yè)化。國(guó)內(nèi)當(dāng)前經(jīng)濟(jì)的發(fā)展加大了對(duì)包裝機(jī)械的需求,而一些知名品牌都是一直在采購(gòu)國(guó)外的包裝機(jī)械,如何改變這一現(xiàn)狀呢,看來國(guó)產(chǎn)包裝機(jī)還需要提升自身的實(shí)力。我國(guó)包裝機(jī)械的技術(shù)水平從整體看先進(jìn)的技術(shù)水平整體看落后2年,在產(chǎn)品的開發(fā)、性能、質(zhì)量、可靠性、服務(wù)等方面的競(jìng)爭(zhēng)中處于劣勢(shì)。
