周口沙河闸是由浅孔闸和深孔闸共同组成。浅孔闸共14孔,配备2×15t、2×25t手电两用固定卷扬式启闭机14组。深孔闸共10孔,配备2×50t固定卷扬式启闭机10组。1975年投入运行后,近20年来经过几届管理人员的不懈努力,一直运行正常。但是,近两年来发现启闭机启闭时有震动现象,而且随着时间的推移,震动逐渐加剧,特别是浅孔闸,有个别启闭机震动最厉害时象打机关枪,下部动滑轮组随着震动前后左右摇摆不停。虽然未影响启闭,但总是隐患和故障。
Zhoukou Shahe gate is composed of shallow hole gate and deep hole gate together. Shallow hole gate a total of 14 holes, equipped with 2 × 15t, 2 × 25t dual-purpose fixed winch Hoist 14 groups. A total of 10 holes deep hole gate, equipped with 2 × 50t fixed winch hoist 10 groups. After put into operation in 1975, after nearly 20 years of unremitting efforts by several managers, has been operating normally. However, in the past two years, it has been found that the hoist vibrates when it is opened and closed. As time goes on, the vibration gradually aggravates. Especially for the shallow hole brake, when individual hoist vibrates the most, Swing around before and after shaking non-stop. Although it does not affect the opening and closing, but always hidden and fault.
