Installation and commissioning of screw hoist
Before installation, it is necessary to check whether the parts are in good condition, whether the lubricating oil is sufficient, whether the bolts are loose, and whether the relevant technical data are consistent.
When installing, it is necessary to keep the level of foundation layout 180 degrees; the contact area between the base of hoist and the plane of foundation layout should be more than 90%; the axis of www.yuanlingujian.com.cn www.aoyou56.com www.huaruizh.com www.aoyouwangluo.com www.fangzhuangmoju.cn www.dangtuqiang.com.cnscrew should be perpendicular to the horizontal plane of the cross beam on the gate platform; and it should be vertical to the ear hole of the gate plate to avoid the inclination of screw, causing local stress and damaging the machine parts.
After installation, it is necessary to make a trial run. As soon as a load-free test is done, the screw is allowed to make two journeys, listen to its abnormal sound, and check whether the installation meets the technical requirements. The second is the load test. Under the rated load, two strokes are made to observe the operation of screw and gate, and whether there are any abnormal phenomena. Only after confirmation is correct can it be officially operated. After a period of load operation, the first maintenance should be carried out. The metal foam produced by friction of new parts in the machine, especially screw, nut, turbine and scroll, should be cleaned lightly, coated with lubricant, sealed tightly, and continued to use.
