Screw hoist
(一) 安装与调试
(1) Installation and commissioning
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 all parts are in good condition, whether the lubricating oil is enough, whether the bolts are loose and whether they are consistent with relevant technical data.
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. During installation, the foundation layout plane must be kept 180 ° horizontal; The contact area between the hoist base and the foundation layout plane shall reach more than 90%; The screw axis shall be perpendicular to the horizontal plane of the beam on the gate platform; It shall be consistent and vertical with the lifting lug hole of the ram to avoid the tilt of the screw rod, resulting in local stress and damage to the 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, trial operation must be carried out. Once no-load test is carried out, let the screw make two strokes, listen to whether there is abnormal sound, and check whether the installation meets the technical requirements. Second, carry out the load test. Under the rated load, make two strokes to observe the operation of the screw and the gate for abnormalities. After confirmation, it can be officially operated. After the load runs for a period of time, the first maintenance shall be carried out. The metal foam generated by the friction of new parts in the machine, especially the screw, nut, turbine and vortex rod, shall be gently cleaned, coated with lubricating oil, tightly sealed and continue to be used.
