編碼器(encoder)是將信號(如比特流)或數(shù)據(jù)進(jìn)行編制、轉(zhuǎn)換為可用以通訊、傳輸和存儲的信號形式的設(shè)備。編碼器把角位移或直線位移轉(zhuǎn)換成電信號,前者稱為碼盤,后者稱為碼尺。按照讀出方式編碼器可以分為接觸式和非接觸式兩種;按照工作原理編碼器可分為增量式和式兩類。增量式編碼器是將位移轉(zhuǎn)換成周期性的電信號,再把這個(gè)電信號轉(zhuǎn)變成計(jì)數(shù)脈沖,用脈沖的個(gè)數(shù)表示位移的大小。式編碼器的每一個(gè)位置對應(yīng)一個(gè)確定的數(shù)字碼,因此它的示值只與測量的起始和終止位置有關(guān),而與測量的中間過程無關(guān)。
伺服閥主要是指電液伺服閥,它在接受電氣模擬信號后,相應(yīng)輸出調(diào)制的流量和壓力。它既是電液轉(zhuǎn)換元件,也是功率放大元件,它能夠?qū)⑿」β实奈⑷蹼姎廨斎胄盘栟D(zhuǎn)換為大功率的液壓能(流量和壓力)輸出。在電液伺服系統(tǒng)中,它將電氣部分與液壓部分連接起來,實(shí)現(xiàn)電液信號的轉(zhuǎn)換與液壓放大。電液伺服閥是電液伺服系統(tǒng)控制的核心。
電機(jī)(英文:Electric machinery,俗稱“馬達(dá)”)是指依據(jù)電磁感應(yīng)定律實(shí)現(xiàn)電能轉(zhuǎn)換或傳遞的一種電磁裝置。電機(jī)在電路中是用字母M(舊標(biāo)準(zhǔn)用D)表示,它的主要作用是產(chǎn)生驅(qū)動轉(zhuǎn)矩,作為用電器或各種機(jī)械的動力源,發(fā)電機(jī)在電路中用字母G表示,它的主要作用是利用機(jī)械能轉(zhuǎn)化為電能。
柱塞泵是液壓系統(tǒng)的一個(gè)重要裝置。它依靠柱塞在缸體中往復(fù)運(yùn)動,使密封工作容腔的容積發(fā)生變化來實(shí)現(xiàn)吸油、壓油。柱塞泵具有額定壓力高、結(jié)構(gòu)緊湊、效率高和流量調(diào)節(jié)方便等優(yōu)點(diǎn)。柱塞泵被廣泛應(yīng)用于高壓、大流量和流量需要調(diào)節(jié)的場合,諸如液壓機(jī)、工程機(jī)械和船舶中。
變送器是從傳感器發(fā)展而來的,凡是能輸出標(biāo)準(zhǔn)信號的傳感器。標(biāo)準(zhǔn)信號是指物理量的形式和數(shù)量范圍都符合國際標(biāo)準(zhǔn)的信號。由于直流信號具有不受線路中電感、電容及負(fù)載性質(zhì)的影響,不存在相移問題等優(yōu)點(diǎn),所以國際電工委員會(IEC)將電流信號 4mA~20mA(DC)和電壓信號 1V~5V(DC)確定為過程控制系統(tǒng)中模擬信號的統(tǒng)一標(biāo)準(zhǔn)。
