放大器是一種適合于開環(huán)比例閥的電子控制單元，導(dǎo)軌安裝式，該控制器輸出電流與參考信號成比例，而與溫度變化及負載阻抗無關(guān)。比例電磁鐵采用PWM電源，可以減小閥的磁性滯環(huán)，提高控制精度。前面板上，裝有用于參數(shù)設(shè)定的調(diào)整電位計，用于改善系統(tǒng)性能。該放大器有三種型號，分別用于單電磁鐵比例閥、雙電磁鐵比例閥和有雙通道控制的單電磁鐵比例閥。每種型號的電子控制單元的大電流和開關(guān)頻率（PWM）互不相同，可根據(jù)使用閥的型號進行選擇（PWM）。

 

電液比例閥是比例控制系統(tǒng)中的主要功率放大元件,按輸入電信號指令連續(xù)地成比例地控制液壓系統(tǒng)的壓辦流量等參數(shù)。與伺服控制系統(tǒng)中的伺服閥相比,在某些方面還有一定的性能差距(主要性能比較如表1所示),但它顯著的優(yōu)點是抗污染能力強,大大地減少了由污染而造成的工作故障,提高了液壓系統(tǒng)的工作穩(wěn)定性和可靠性。另一方面比例閥的成本比伺服閥低，結(jié)構(gòu)也簡單,已在許多場合獲得廣泛應(yīng)用。

 

比例閥按功能分為三大類

(1)比例壓力閥。有溢流閥減壓閥,分別有直動和先導(dǎo)兩種結(jié)構(gòu);可連續(xù)地或按比例地遠程控制其輸出油液壓力;

(2)比例換向閥。有直動和先導(dǎo)兩種結(jié)構(gòu),直動閥有帶位移傳感器和不帶位移傳感器兩類。由于使用了比例電磁鐵閥芯不僅可以換位，而且換位的行程可以連續(xù)地或按比例地變化。因而連通油口間的通流面積也可以連續(xù)或按比例地變化。所以比例換向閥不僅能夠控制執(zhí)行元件的方向而且能夠控制其速度。因為這個原因比例閥中的比例換向閥應(yīng)用也普遍;

(3)比例流量閥。有比例調(diào)速閥和比例溢流流量控制閥,可連續(xù)地或按比例地遠程控制其輸出流量。

比例閥的輸入單元是電-機械轉(zhuǎn)換器,它將輸入的電信號轉(zhuǎn)換成機械量轉(zhuǎn)換器有伺服電機和步進電機力馬達和力矩馬達比例電磁鐵等形式。但常用的比例閥大都采用了比例電磁鐵，比例電磁鐵根據(jù)電磁原理設(shè)計,能使其產(chǎn)生的機械量(力或力矩和位移)與輸入電信號(電流)的大小成比例,再連續(xù)地控制液壓閥閥芯的位置，進而實現(xiàn)連續(xù)地控制液壓系統(tǒng)的壓力方向和流量。比例電磁鐵的結(jié)構(gòu)，它由線圈、銜鐵推桿等組成,當有信號輸入線圈時,線圈內(nèi)磁場對銜鐵產(chǎn)生作用力,銜鐵在磁場中按信號電流的大小和方向成比例連續(xù)地運動,再通過固連在一起的銷釘帶動推桿運動,從而控制滑閥閥芯的運動。應(yīng)用的比例電磁鐵是耐高壓直流比例電磁鐵。

 

比例電磁鐵的類型按照工作原理主要分為

如下幾類:

(1)力控制型

這類電磁鐵的行程短，只有1 5mm,輸出力與輸入電流成正比,常用在比例閥的先導(dǎo)控制級

上:

(2)行程控制型

由力控制型加負載彈簧共同組成，電磁鐵輸出的力通過彈簧轉(zhuǎn)換成輸出位移,輸出位移與輸入電流成正比，工作行程達3mm,線性好，可以用在直控式比例閥上;

(3)位置調(diào)節(jié)型

銜鐵的位置由傳感器檢測后,發(fā)出一個閥內(nèi)反饋信號,在閥內(nèi)進行比較后重新調(diào)節(jié)銜鐵的位置。閥內(nèi)形成閉環(huán)控制,精度高,銜鐵的位置與力

無關(guān)，精度高的比例閥如德國的博世意大利的阿托斯等都采用這種結(jié)構(gòu)。

比例閥與放大器配套使用放大器采用電流負反饋,設(shè)置斜坡信號發(fā)生器階躍函數(shù)發(fā)生器、PD調(diào)節(jié)器反向器等,控制升壓降壓時間或運動加速度及減速度。斷電時, 能使閥芯處于安全位置。

比例電磁鐵和液壓閥組成電液比例閥。由于比例電磁鐵可以在不同的電流下得到不同的力(或行程),因此可以無級改變壓力、流量。故比例電磁鐵是比例閥的關(guān)鍵元件。
