比例環(huán)節(jié)

比例環(huán)節(jié)也稱為無慣性環(huán)節(jié),對(duì)液壓缸或馬達(dá)，忽略液壓油的可壓縮性和泄漏,液壓缸的流量Q= VA。其中V為活塞速度;A為活塞面積。其傳遞函數(shù)為: g(s)= V (s)/Q(s)= 1/A =式中K為比例環(huán)節(jié)放大系數(shù)或增益,表示輸入量經(jīng)過放大K倍后輸出。

比例控制系統(tǒng)

比例控制系統(tǒng)根據(jù)有無反饋分為開環(huán)控制和閉環(huán)控制。如比例閥控制液壓缸或馬達(dá)系統(tǒng)可以實(shí)現(xiàn)速度位移轉(zhuǎn)速和轉(zhuǎn)矩等的控制。

由于開環(huán)控制系統(tǒng)的精度比較低,無級(jí)調(diào)節(jié)系統(tǒng)輸入量就可以無級(jí)調(diào)節(jié)系統(tǒng)輸出量力速度以及加減速度等。這種控制系統(tǒng)的結(jié)構(gòu)組成簡(jiǎn)單,系統(tǒng)的輸出端和輸入端不存在反饋回路,系統(tǒng)輸出量對(duì)系統(tǒng)輸入控制作用沒有影響,沒有自動(dòng)糾正偏差的能力,其控制精度主要取決于關(guān)鍵元器件的特性和系統(tǒng)調(diào)整精度，所以只能應(yīng)用在精度要求不高并且不存在內(nèi)外干擾的場(chǎng)合。開環(huán)控制系統(tǒng)一.般不存在所謂穩(wěn)定性問題。

電液比例閥簡(jiǎn)稱比例閥。普通液壓閥只能通過預(yù)調(diào)的方式對(duì)液流的壓力、流量進(jìn)行定值控制。但是當(dāng)設(shè)備機(jī)構(gòu)在工作過程中要求對(duì)液壓系統(tǒng)的壓力、流量參數(shù)進(jìn)行調(diào)節(jié)或連續(xù)控制，例如.要求工作臺(tái)在工作進(jìn)給時(shí)按慢、快、慢連續(xù)變化的速度實(shí)現(xiàn)進(jìn)給，或按一定精度模擬某個(gè)控制曲線實(shí)現(xiàn)旅力控制.普通液壓閥則實(shí)現(xiàn)不了。這時(shí)可以用電液比例閥對(duì)液壓系統(tǒng)進(jìn)行控制。

電液比例閥是一種按輸入的電信號(hào)連續(xù)地、按比例地控制液壓系統(tǒng)的液流方向、流量和壓力的閥類。它由機(jī)械比例轉(zhuǎn)換裝置和液壓控制閥本體兩大部分構(gòu)成.前者將輸入的電信號(hào)連續(xù)地按比例地轉(zhuǎn)換為機(jī)械力和位移輸出，后者在接受這種機(jī)械力和位移之后、按比例連續(xù)地輸出壓力和流量.

比例換向插裝閥，先導(dǎo)式，帶集成電子元件 (OBE) 或外部控制電子元件

2WFC；2WFCE

2WFCE 型先導(dǎo)式比例方向閥主要包括：

封面 (1)

主舞臺(tái) (2)

帶比例電磁閥的先導(dǎo)控制閥 (3)

帶有位置傳感器和模擬接口 (4) 的集成電子設(shè)備或作為模塊放大器的外部控制電子設(shè)備

電子裝置（集成的或外部的）將****的控制值與主級(jí) (2) 的控制閥芯的位置實(shí)際值進(jìn)行比較。在控制偏差的情況下，先導(dǎo)控制閥 (3) 的電磁閥被激活。這樣，控制閥芯被調(diào)整。根據(jù)控制偏差，主級(jí) (2) 的控制室要么用先導(dǎo)油加壓（主級(jí)關(guān)閉），要么卸載（主級(jí)打開）。行程和節(jié)流孔橫截面與控制值成比例地控制，直到控制偏差得到糾正。

電源電壓故障

如果較小電源電壓出現(xiàn)故障或低于較低電壓，則啟用將斷開（僅接口 B1 和 G1），并且在電磁鐵導(dǎo)線斷線的情況下，電子設(shè)備將使先導(dǎo)控制閥 (3) 的電磁鐵斷電. 主級(jí) (2) 的控制閥芯使用端口 X 處的可用壓力和主級(jí)彈簧的力安全地移動(dòng)到其閥座，并阻止 A 和 B 之間的流動(dòng)。

流量控制功能

與壓力補(bǔ)償器結(jié)合使用時(shí)，先導(dǎo)式比例方向閥可用于流量的壓力補(bǔ)償控制。

減壓閥是通過調(diào)節(jié)，將進(jìn)口壓力減至某一需要的出口壓力，并依靠介質(zhì)本身的能量，使出口壓力自動(dòng)保持穩(wěn)定的閥門。從流體力學(xué)的觀點(diǎn)看，減壓閥是一個(gè)局部阻力可以變化的節(jié)流元件，即通過改變節(jié)流面積，使流速及流體的動(dòng)能改變，造成不同的壓力損失，從而達(dá)到減壓的目的。然后依靠控制與調(diào)節(jié)系統(tǒng)的調(diào)節(jié)，使閥后壓力的波動(dòng)與彈簧力相平衡，使閥后壓力在一定的誤差范圍內(nèi)保持恒定。
