1. 安装前，一定要检查各零件是否良好，润滑油是否上足，螺栓有无松动，与其有关技术数据是否相符。
1. before installation, be sure to check whether the parts are good, whether the lubrication is sufficient or not, whether the bolts are loose or not, and whether the technical data is consistent with it.
2. 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。
2. when installed, must maintain a basic layout level of 180 degrees; and the contact area of the base and the base closing machine layout to reach more than 90%; the screw axis perpendicular to the horizontal plane of the upper beam gate station; consistent vertical hanging ears and a gate, avoid screw tilt, caused by the stress of the local damage to parts.
3. 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。
3. after installation, must be run without a load test, let the screw for two strokes, listen to their unusual sound detection installation in accordance with the technical requirements. Two for the load test, under the rated load, make two trips, observe the operation of the screw and gate, whether or not abnormal phenomenon. Confirm the error before you can officially run. In operation for a period of time to load, maintenance for the first time, the metal foam machine in the new mechanical friction especially screw, nut, turbine, vortex, to wash clean, lubricate, seal, continue to use.
