大型液壓站調節閘瓦間隙的動作過程  

液壓站調節(jie)閘(zha)瓦間隙(xi)的動作(zuo)過(guo)程(cheng)

B157、B159液壓站調(diao)閘瓦(wa)間隙(xi)動(dong)作過程如下：

1 )G3通電(dian)，G1、G2、G4、G5、G6斷電(dian)，B157液(ye)壓站游動(dong)卷筒(tong)制(zhi)動(dong)器(qi)(qi)(qi)(qi)(別59液(ye)壓站卷筒(tong)左邊(bian)制(zhi)動(dong)器(qi)(qi)(qi)(qi))處于制(zhi)動(dong)狀態(tai)，B157液(ye)壓站固定(ding)卷筒(tong)制(zhi)動(dong)器(qi)(qi)(qi)(qi)(趴(pa)59液(ye)壓站卷筒(tong)右(you)邊(bian)制(zhi)動(dong)器(qi)(qi)(qi)(qi))處于松閘(zha)(zha)狀態(tai)，即可以(yi)調節此制(zhi)動(dong)器(qi)(qi)(qi)(qi)的閘(zha)(zha)瓦間隙(xi)。

2 )G4、G5通電，Gl、G2、G3、G6斷電，B157液壓(ya)站(zhan)固定卷(juan)(juan)筒(tong)(tong)制(zhi)動(dong)器(B159液壓(ya)站(zhan)卷(juan)(juan)筒(tong)(tong)右邊制(zhi)動(dong)器)處于(yu)制(zhi)動(dong)狀(zhuang)態(tai)(tai)，B157液壓(ya)站(zhan)游動(dong)卷(juan)(juan)筒(tong)(tong)制(zhi)動(dong)器(趴59液壓(ya)站(zhan)卷(juan)(juan)筒(tong)(tong)左(zuo)邊制(zhi)動(dong)器)處于(yu)松(song)閘狀(zhuang)態(tai)(tai)，　　3 )G4、G3斷電，制(zhi)動(dong)器處于(yu)全制(zhi)動(dong)狀(zhuang)態(tai)(tai)，等待(dai)下次開車。

這兩種液(ye)壓(ya)站(zhan)在井口(kou)，緊急情況下(xia)二級(ji)制(zhi)動(dong)(dong)解除(chu)，只有(you)G5斷電(dian)一級(ji)制(zhi)動(dong)(dong)。　　液(ye)壓(ya)站(zhan)為盤(pan)(pan)形制(zhi)動(dong)(dong)器(qi)提供了不同(tong)油(you)壓(ya)的(de)油(you)，油(you)壓(ya)變(bian)化由電(dian)液(ye)調壓(ya)裝置6來調節，這時安全制(zhi)動(dong)(dong)部分的(de)電(dian)磁閥G3、G4、G5帶電(dian)，油(you)路通，壓(ya)力(li)油(you)通過(guo)管(guan)路分別進入各盤(pan)(pan)形制(zhi)動(dong)(dong)器(qi)。油(you)壓(ya)的(de)變(bian)化，通過(guo)提升機(ji)司機(ji)控(kong)制(zhi)電(dian)液(ye)調壓(ya)裝置的(de)信號電(dian)流大小來實現，從而達(da)到(dao)調節制(zhi)動(dong)(dong)力(li)矩(ju)的(de)目的(de)。
