水利闸门的制作厂家广泛用于水利工程闸口的启闭，是农田灌溉，水产饲养，农业经济开发区，污水处理厂，水利发电站，水库(水闸，堤堰，地道，管道)等进水，退水闸的配套机械，山区，平原有，无电区域均可运用。
手摇螺杆启闭机该怎么安装呢？1，在安装螺杆启闭机时一定要保持底座基础布置平面水平180o;启闭机底座与基础布置平面的接触面积要达到90%以上;螺杆轴线要垂直闸台上衡量的水平面;要与闸板吊耳孔文和垂直，避免螺杆倾斜，造成局部受力而损坏机件。机械化生产方式的成功转变得益于一些先进机械的运用
2，将手动螺杆启闭机置于安装位置。
把一个限位盘套在螺杆上，将螺杆从横梁的下部旋入机器中，当螺杆从机器的上方露出后，再套上限位盘。
螺杆的下方与闸门连接。
3，对于安装启闭机的基础必须稳固安全。
机座和基础构件的混凝土，按图纸的规定浇筑，在混凝土强度未达到设计强度时，不准拆除和改变启闭机的临时支撑，更不得进行试调和试运转。
4，在安装时根据闸门起吊中心线，找正中心使纵横向中心线偏差不超过正负3mm,高程偏差不超过正负5mm。
然后浇注二期混凝土或与预埋钢板连接。
5，以免影响止水效果
电动启闭时将行程开关的常闭触点接到控制电动机运转的总交流接触器的线圈回路，将行程开关的常开触点接入报警器线路，闭闸或误操作时，闸门利用自重下降，当闸板下缘接触到闸底或在下降途中遇到障碍物阻止闸门下降时，闸门将静止不动。It is widely used for opening and closing sluice gates of water conservancy projects. It can be used in farmland irrigation, aquaculture, agricultural economic development zones, sewage treatment plants, hydroelectric power stations, reservoirs (sluices, dikes, tunnels, pipes) and other intake and outlet machinery, mountainous areas, plains with and without electricity. How to install the hand screw hoist? 1. When installing screw hoist, it is necessary to keep the base layout horizontal 180o; the contact area between the base and the base layout plane of the hoist should be more than 90%; the screw axis should be vertical to the horizontal plane measured on the gate platform; and it should be vertical and vertical to the ear of the gate to avoid the inclination of the screw, resulting in local stress and damage to the machine parts. Successful transformation of mechanized production mode benefits from the use of some advanced machinery. 2. Manual screw hoist is placed in the installation position. Put a limit disc on the screw, and screw the screw from the lower part of the beam into the machine. When the screw is exposed from the upper part of the machine, then the upper limit disc is set. The lower part of the screw is connected with the gate. 3. The foundation of hoist installation must be stable and safe. When the concrete strength of the machine base and foundation components is not up to the design strength, it is not allowed to dismantle and change the temporary support of the hoist, let alone to carry out commissioning and commissioning when the concrete strength of the machine base and foundation components is poured in accordance with the provisions of the drawings. 4. In installation, according to the center line of gate hoisting, find the correct center so that the deviation of longitudinal and transverse center line does not exceed plus or minus 3 mm, and the elevation deviation does not exceed plus or minus 5 mm. The second stage concrete is then poured or connected with the embedded steel plate. 5. In order to avoid affecting the effect of water stopping, the normal closed contacts of the stroke switch are connected to the coil circuit of the total AC contactor which controls the operation of the motor, and the normal open contacts of the stroke switch are connected to the alarm circuit. When the gate is closed or misoperated, the self-weight of the gate decreases. When the lower edge of the gate touches the bottom of the gate or meets during the descending process. When obstacles prevent the gate from falling, the gate will remain stationary.
