The screw type hoist is a kind of machine that connects the threaded rod directly or through the guide slide block, connecting rod and the gate leaf, and the screw moves up and down to open and close the gate. With the extensive development of water conservancy and hydropower projects, hoist gates and sluice gates are widely used in projects such as reservoir irrigation areas, river dykes and water conservancy power stations.

安装调试

Installation and debugging

安装时，一定要保持基础布置平面水平180°；启闭机底座与基础布置平面的接触面积要达到90%以上；螺杆轴线要垂直于闸台上横梁的水平面；要与闸板吊耳孔吻合垂直，避免螺杆倾斜，造成局部受力而损坏机件。

During installation, the plane level of the basic layout must be kept 180 degrees; the contact area of the base and the basic layout plane should be above 90%; the axis of the screw should be perpendicular to the horizontal plane of the beam on the gate; it should be in a vertical line with the sluice ear hole to avoid the tilt of the screw and damage the parts by the local force.

安装后，一定要作试运行，一作无载荷试验，即让螺杆作两个行程，听其有无异常声响，检测安装是否符合技术要求。二作载荷试验，在额定载荷下，作两个行程，观察螺杆与闸门的运行情况，有无异常现象。确认无误后，方可正式运行。在载荷运行一段时间后，要进行首次保养，把机内新机件磨擦产生的金属沫特别是螺杆、螺母、涡轮、涡杆，要轻洗干净，涂上润滑油，密封严实，继续使用。

After installation, it is necessary to make a trial operation, without a load test, that is, let the screw make two trips, listen to its abnormal sound, and check whether the installation meets the technical requirements.tongpixiu.89ix.comshuzhiwa.89ix.com jiansuji.89ix.com lalianji.89ix.com gelishanm.89ix.comzaolang.89ix.com Two make a load test, make two journeys under the rated load, observe the operation of screw and gate, whether there is any abnormal phenomenon. After confirmation, it can run formally. After the load is running for a period of time, the first maintenance, the metal foam produced by the friction of the new machine parts, especially the screw, nut, turbine and vortex rod, should be washed clean, coated with lubricating oil, sealed and continued to use.

使用保养

Use and maintenance

操作人员必须掌握启闭机的结构、性能与操作方法，并有一定的机械知识，以确保机器的正常运转。

The operator must master the structure, performance and operation method of the hoist, and have certain mechanical knowledge to ensure the normal operation of the machine.

操作前，对启闭机进行全面检查，各部位润滑情况是否良好，螺栓有无松动。电动启闭时检查电源线路是否接通，开关是否良好。

Before operation, check the hoist and check whether the lubrication conditions are good and whether the bolts are loose or not. When opening and closing the electric motor, check whether the power line is connected, and whether the switch is good.

螺杆式启闭机主要用在水库/灌区的闸门升降的控制上！

The screw hoist is mainly used in the control of the gate of the reservoir / irrigation area.
