現(xiàn)貨供應(yīng)美國(guó)VICKERS威格士比例閥 VICKERS比例閥一般采用兩端承壓面積不等的差徑活塞結(jié)構(gòu)。工作原理如圖12-9所示，比例閥不工作時(shí)，差徑活塞2在彈簧3的作用下處于上極限位置。此時(shí)閥門(mén)1保持開(kāi)啟，因而在輸入控制壓力P1與輸出壓力P2從零同步增長(zhǎng)的初始階段，總是P1=P2。但是壓力P1的作用面積為A1=π（D2-d2）/4，壓力閥的作用面積為A2=πd2/4，因而A2>A1，故活塞上方液壓作用力大于活塞下方液壓作用力。在P1、P2同步增長(zhǎng)過(guò)程中當(dāng)活塞上、下兩端液壓作用之差超過(guò)彈簧3的預(yù)緊力時(shí)，活塞便開(kāi)始下移。當(dāng)P1和P2增長(zhǎng)到一定值Ps時(shí)活塞2內(nèi)腔中的閥座與閥門(mén)1接觸，進(jìn)油腔與出油腔即為隔絕。此即比例閥的平衡狀態(tài)。 現(xiàn)貨供應(yīng)美國(guó)VICKERS威格士比例閥 CG5V-6CM-DMU-H5-20

分解：首先將美國(guó)威格士vickers比例閥夾在臺(tái)鉗上，用扳手?jǐn)Q下閥蓋8，并拆下密封圈。然后取出襯套2、柱塞1、密封圈3、彈簧座4、彈簧5、彈簧座6和密封圈7，其分解如圖12-13所示。
2.檢修：檢查閥體的表面和柱塞的外表面是否光潔、無(wú)銹蝕，相互配合的零件之間是否有過(guò)大間隙。如發(fā)現(xiàn)有較輕的缺陷，可用適當(dāng)?shù)姆椒ㄓ枰韵?；倘若缺陷難以消除，則應(yīng)更換感載比例閥總成（因?yàn)殚y體和柱塞不作為備件供應(yīng)）。 每次維修時(shí)，對(duì)所有密封件，即使看上去完好無(wú)損，也應(yīng)予以更換。而且在裝配之前，應(yīng)以規(guī)定使用的制動(dòng)液潤(rùn)滑各零部件。要避免密封件與汽油或其它溶劑接觸。
三、美國(guó)威格士vickers比例閥的調(diào)整 為了確保感載比例閥能在必要時(shí)介入制動(dòng)回路，需對(duì)扭桿進(jìn)行調(diào)整。但應(yīng)注意：液壓回路中有壓力時(shí)，不可對(duì)拉桿進(jìn)行調(diào)整；檢查應(yīng)在緩慢的升壓過(guò)程中進(jìn)行；檢查感載比例閥時(shí)，制動(dòng)系統(tǒng)的所有其它零件都應(yīng)處于完好狀態(tài)。在對(duì)汽車(chē)進(jìn)行改裝時(shí)，若更換了鋼板彈簧，則應(yīng)同時(shí)更換說(shuō)明牌，并對(duì)其上數(shù)據(jù)做相應(yīng)的修正。 美國(guó)威格士vickers比例閥調(diào)整方法有兩種：
1.檢查行程
1）秤汽車(chē)后部的重量，使其空載；
2）起動(dòng)發(fā)動(dòng)機(jī)；
3）拆下感載比例閥防塵罩2便可以看到柱塞與扭桿的接觸部分；
4）將制動(dòng)踏板踩到底，然后用厚薄規(guī)檢查柱塞與扭桿之間的間隙，其值應(yīng)為0.1mm；
5）按照上述方法模擬滿載時(shí)感載比例閥的狀態(tài)，然后按說(shuō)明牌所給定位的數(shù)值測(cè)量扭桿的行程。
2.檢查輸入和輸出壓力
1）擰下檢測(cè)口的保護(hù)蓋，然后裝上壓力表，讓發(fā)動(dòng)機(jī)怠速運(yùn)轉(zhuǎn)，緩慢踏下制動(dòng)踏板，直至感載比例閥前壓力表讀數(shù)為10MPa為止，保持此壓力值不變。
2）按表12-8所示的模擬負(fù)荷加載，使感載比例閥之后的壓力表讀數(shù)滿足表中要求。無(wú)論哪種方法，如果美國(guó)威格士vickers比例閥后壓力表的讀數(shù)與要求不符，則應(yīng)調(diào)整拉桿，如圖12-12所示，其長(zhǎng)度應(yīng)符合要求。
調(diào)整結(jié)束后，還應(yīng)檢查整車(chē)的制動(dòng)狀況是否完好 美國(guó)VICKERS威格士比例閥（CG5V系列比例方向閥） VICKERS威格士伺服閥 VICKERS威格士電磁閥 VICKERS威格士換向閥 VICKERS威格士流量閥 VICKERS威格士壓力閥 VICKERS威格士柱塞泵 VICKERS威格士變量柱塞泵 VICKERS威格士定量柱塞泵 VICKERS威格士柱塞泵馬達(dá)配件 VICKERS威格士馬達(dá) VICKERS威格士放大器 VICKERS威格士葉片泵 CG5V-6CM-DMU-H5-20 CG5V6FWDMUH520 CG5V6GWDMUH520 PCG5V-8ADE-VM-U-H7-11 PCG5V-8A-E-VM-U-H5-20 CG5V6GWDMUH711 CG5V-8GW-DMU-H520 CG5V-8GW-DF-VM-U-H7-11 CG5V6GWDVMUH520 CG5V8CWDVMUH520 CG5V-6GW-D-M-U-H5-20 CG5V-8GM-D-M-U-H-20 CG5V-6GM-D-M-U-H-20 CG5V6CWDMUH711 CG5V6FKDMUH711 CG5V8GWDMUC611 ECG510B0BMUA621TG KBCG5-3-40D-Z-T-M2-4-A-PE7-H1-10 DG5V-7-6C-M-U-H5-40
