閉機試動前應進行下列檢查:钢丝绳起端固定牢靠,在卷筒和滑轮中缠绕应无交叉现象。所有电器及动力回路的接线应正确、整齐,有良好的绝缘和可靠的接地。检查所有机械部件、连接部件和各种保护装置及润滑系统,注油情况应符合要求。用手转动制动轮,使卷筒旋转一圈,不得有卡阻现象。检查和调试高度指示及制动器。 The following inspections should be carried out before the hoist is tested: the wire rope ends are firmly fixed, and there should be no crossover between the drum and the pulley. The wiring of all electrical and power circuits should be correct and neat, with good insulation and reliable grounding. Check all mechanical parts, connecting parts and all kinds of protective devices and lubricating system. The oil filling condition should be up to the requirement. Turn the brake wheel with your hand, so that the drum can be rotated one circle without blocking. Check and debug the height indication and brake. 空载试运转。安装检查合格后,方可进行空载试试运转,空载试运转要求起升机构全程上下三次,并检查下列电器与机械部分。电动机运行平稳,三相电流平衡,电器设备控制可靠,无异常发热现象。制动闸瓦应全部离开制动轮。机构部件的运转平稳,无冲击和其它异常现象。所有电器保护装置,限位行程保护,过负荷保护装置等动作准确可靠。钢丝绳不应与其它部件碰刮。 No load test operation. After the installation is checked, the no-load trial operation can be carried out. The no-load trial run requires the lifting mechanism to go up and down three times, and check the following electrical and mechanical parts. The motor runs smoothly, the three-phase current is balanced, the electrical equipment is controlled reliably, and there is no abnormal heating phenomenon. Brake shoe should all leave the brake wheel. The operation of the mechanism parts is smooth, no impact and other abnormal phenomena. All electrical protection devices, limit stroke protection, overload protection devices and other actions are accurate and reliable. The wire rope should not be touched with other parts. 动负荷试运转:记录上、下游水位及机组带负荷的大小。测量启动主机后再测各线路电流值是否符合要求。检查电气回路动作是否准确。 Dynamic load test run: record the upstream and downstream water level and the load of the unit. After measuring the starting host, the current value of each line is measured to meet the requirements. Check whether the electrical circuit is accurat
