经常进行必要的维护作业可以减少磨损，消除隐患和故障，保持设备始终处于良好的技术状况，以延长使用寿命，减少运行费用，确保安全可靠地运行。 Frequent necessary maintenance operations can reduce wear and tear, eliminate hidden dangers and failures, and keep the equipment in good technical condition, so as to extend service life, reduce operation cost and ensure safe and reliable operation. 维修保养内容技术：包括“清洁、紧固、调整、润滑”八字作业。 Maintenance and maintenance content technology: including "clean, fasten, adjust, lubricate" Eight word operation. 清洁是针对启闭机的外表、内部及制动轮圆周面、电器接点、电磁铁吸合接触面和周围环境，定期进行清洁。启闭机房内外门窗一周清扫一次，场地上的工器具应及时整理，摆放整齐。 Cleaning is for the opening and closing of the exterior, internal and brake wheel circle, electrical contacts, electromagnet to absorb the contact surface and the surrounding environment, regular cleaning. The inside and outside doors and windows of the open and closed machine room are cleaned once a week, and the facilities on the site should be arranged in time and placed in order. 紧固是对压力油系统中的螺纹管接头、密封用压盖螺栓等进行紧固，防止松动造成漏油；对基础、法兰等各种定位螺栓、高强螺栓、钢丝绳压紧螺栓和吊具联接螺栓进行紧固，如松动会改变被联接零部件的受力和运动情况，并构成事故隐患。 Is used for fastening the cap bolt fastening seal of screw oil pressure in the system, pipe joints, prevent loosening caused by oil leakage; fastening the base flange and so on various positioning bolt, high strength bolt, wire rope bolts and sling bolts, such as loose coupling parts will change by the movement and force, and a hidden danger of accident. 调整： Adjustment: ①对轴瓦与轴颈、滚动轴承的配合间隙、齿轮啮合的顶、侧间隙、制动器闸瓦与制动轮之间的松闸间隙调整。 The clearance gap between the axle bush and the axle neck and the rolling bearing, the top of the gear meshing, the side gap, the brake shoe and the brake wheel are adjusted. ②对制动器的松闸行程、离合器的离合行程、安全 限位开关的限位行程和闸门启闭位置指示行程进行调整。 Second, it adjusts the loosening trip of the brake, the clutch departure, the limit stroke of the safety limit switch and the position of the gate opening and closing. ③对转动皮带、链条等松动及弹簧弹力大小的调整。④电流、电压、制动力矩、启闭机的流量压力、速度等 调整。 The adjustment of the loosening of the rotating belt and the chain and the size of the spring force. (4) the adjustment of current, voltage, braking torque, flow pressure, speed and so on. 润滑：对启闭设备中有相对运动的零部件，均需保持良好的润滑。 Lubrication: all parts with relative motion in the open and close equipment need to be well lubricated. 维修养护是闸门启闭机运行管理的重要内容，启闭机的维护应本着“安全第一，预防为主”原则，必须做到“经常维护，随时维修，养重于修，修重于抢。” Maintenance and repair is an important part of operation and management of gate hoist. Hoist maintenance should be based on "safety first and prevention first" principle. We must "maintain regularly, maintain at any time, maintain more than repair, repair heavier than grab."
