4WREE6E32-2X/G24K31/A1V-655比例方向控制閥

二位四通和三位四通比例方向直控閥，閥芯帶位移反饋

型號 4WRE 和 4WREE

通經(jīng)6 和 10

2X 系列

高工作壓力 315 bar

大流量 80 L/min (NS6)

大流量 180 L/min (NS6)

特點(diǎn)：

— 直控式比例換向閥可以控制液流的方向和大小

— 閥的控制通過帶中心螺紋的比例電磁鐵實(shí)現(xiàn)，線圈可單   獨(dú)拆卸

— 帶電反饋

— 板式連接結(jié)構(gòu) 孔型符合：DIN 24 340 , A 型，ISO        4401  和 CETOP-RP 121 H

— 控制閥芯由彈簧對中

— 4WREE型帶內(nèi)置放大器，接口形式為A1或F1

— 4WRE型使用的放大器：

   * 數(shù)字式放大器VT-VRPD-2-1X/V0/0

   * 模擬式放大器VT-VRPA2-，-1X

工作原理：二位四通和三位四通比例方向閥為直控，板式結(jié)構(gòu)；由比例電磁鐵操作，比例電磁鐵帶中心螺紋，線圈可單獨(dú)拆卸，電磁鐵的控制可通過外部放大器（WRE型）或內(nèi)置的放大器（WREE型）

液壓比例控制系統(tǒng)

以比例控制元件完成動力與運(yùn)動方向控制，分為比例壓力閥、比例流量閥、比例方向閥及比例方向流量閥，可為模擬量輸入或數(shù)字量輸入，視是否帶反饋分為開環(huán)控制與閉環(huán)控制，一般獲得頻率不是很高(10HZ)以內(nèi)，高頻響閥可實(shí)現(xiàn)較高頻率。

若精度要求不高可考慮使用電液比例控制系統(tǒng)，一般電液比例控制系統(tǒng)可達(dá)至以下精度

位置精度- 3 mm

速度精度帶壓力補(bǔ)償器- 3%

加減速斜坡時間-0.5秒

壓力帶位移傳感器的產(chǎn)品-比例壓力閥設(shè)定的0.3% (如壓力設(shè)定為200bar,精度可達(dá)0.6bar)

一般的多驅(qū)動器液壓系統(tǒng)皆要求流量及壓力控制，提供比例壓力及流量控制系統(tǒng)

開環(huán)式比例壓力及流量控制可用于定量泵及變量泵系統(tǒng)。

速度和流量比例控制的分別是:

流量控制只控制供油量,并不控制驅(qū)動元件的運(yùn)動方向;

若系統(tǒng)負(fù)載及變速要求高，則要使用速度控制系統(tǒng)。

速度比例控制多用于自動化控制、注塑機(jī)、壓力機(jī)等

力士樂REXROTH比例方向閥，先導(dǎo)操作

力士樂REXROTH二位四通和三位四通比例方向閥，直動式，不帶電氣位置反饋，不帶集成式放大版（OBE）4WRZ

交流電磁鐵:使用電壓為交流110、220、380V。特點(diǎn)是啟動力非常大，不需要專門的電源，吸合、釋放快，動作時間約為0.01 ~0.03s。缺點(diǎn)是電源電壓下降15%以上，電磁鐵吸力明顯減小，若銜鐵不動作，干式電磁鐵會在10~15min (濕式1~1.5h) 后燒壞線圈，且沖擊及噪聲非常大，壽命低，允許切換頻率為10次1分。

直流電磁鐵:使用電壓為直流110和24V,工作可靠，吸合釋放時間約為0.05~ 0.08s,切換頻率般為120次/分，沖擊小、體積小、壽命長，但需要專門的直流電源，成本較高。

交流本整型電磁鐵:電磁鐵是直流的，電磁鐵本身帶整流器，通入交流電經(jīng)整流后再供給直流電磁鐵。

干式電磁鐵:電磁鐵線圈、鐵芯與軛鐵處于空氣中而不和油液接觸。電磁鐵與閥連接時，在推桿處設(shè)置密封圈，避免了油液進(jìn)入電磁鐵，而且裝拆方便。為了防止回油進(jìn)入干式電磁鐵中，要求換向閥的回油壓力不能太高。

濕式電磁鐵:濕式電磁鐵的推桿與閥芯連成一體,取消了推桿處的動密封，所以摩擦力小
