    留意闸门启闭机厂家丝杆能否按要求的方向中止移动,电机、变速箱运转能否良好,变速箱与丝杆转轮能否同步运动。 
观察电机转速、温升能否正常,振动能否过大,声响能否异常。若发现异常情况时,应立即停机反省,防止设备变形或损坏,并向调度人和分管工程指点报告。 启闭终了停机后,应再次校核闸门开关丝数量能否对。
闸门用于封锁和开放泄(放)水通道的控制设备。水工建筑物的重要组成部分,可用以阻拦水流,控制水位、调理流量、排放泥沙和飘浮物等。(1)按制造材料划分。主要有木质闸门、木面板钢构架闸门、铸铁闸门、钢筋混凝土闸门以及钢闸门。(2)按闸门门顶与水平面相对位置划分。主要有露顶式闸门和潜没式闸门。(3)按义务性质划分。主要有义务闸门、事故闸门和检修闸门。(4)按闸门启闭方法划分。主要有用机械操作启闭的闸门和使用水位涨落时闸门所受水压力的变化控制启闭的水力自动闸门。(5)按门叶不同的支承方式划分。主要由定轮支承闸门、铰支承闸门、滑道支承的闸门、链轮闸门、串辊闸门、圆辊闸门等。

   Pay attention to whether the screw rod of gate hoist can stop moving in the required direction, whether the motor and gearbox can run well, and whether the gearbox and the screw wheel can move synchronously. Observe whether the motor speed, temperature rise can be normal, whether the vibration can be too large, whether the sound can be abnormal. If abnormal conditions are found, the machine should be stopped immediately for reflection, to prevent equipment deformation or damage, and report to the dispatcher and the project in charge. After the shutdown, the number of switch wires should be checked again. The gate is used to block and open the control equipment of the discharge (discharge) channel. An important part of hydraulic structures can be used to block water flow, control water level, regulate flow, discharge sediment and floats, etc. (1) According to manufacturing materials. There are mainly wooden gates, steel frame gates with wood panels, cast iron gates, reinforced concrete gates and steel gates. (2) According to the relative position of gate top and horizontal plane. There are mainly open-top gate and submerged gate.  (3) According to the nature of obligations. There are mainly obligatory gates, accident gates and overhaul gates. (4) According to the method of gate opening and closing. Mainly use mechanical operation to open and close the gate and use the change of water pressure when the water level rises and falls to control the opening and closing of the hydraulic automatic gate. (5) According to different supporting modes of door blades. Mainly by fixed wheel support gate, hinge support gate, slideway support gate, sprocket gate, series roller gate, round roller gate and so on.
