这是必要的,额定输出电流 桥式起重机 inverter is greater than the steady-state power current at the organization’s great load torque. The operating organization of the crane consists of the operating organization of the overhead crane, the operating lever and the operating lever. With the display, control and alarm function.
The overload capacity of the overhead crane is very strong. Due to the different operating systems of the organization, the promised output torque of the motor is different from the data on the nameplate. In order to ensure that the motor temperature rise does not exceed the standard, the organization selects the motor whose promised output power is greater than or equal to the organization’s steady-state power, and the rated current of the inverter should be greater than the organization’s current in steady-state operation. Regarding the S2 operating system with long-term full-load operation, it is necessary to confirm whether the promised output current value of the inverter is required for full-load.
超载限制器采用钢丝绳角度传感器,即钢丝绳加载后需要拉紧的张力。力使传感器块轻微变形以获得相应的数据。然后,微电脑利用这些数据进行重量显示和超载限制控制,达到额定吨位后打开正常关闭点。桥式起重机起升电路断线、停止运行、扩大阅读:电动双梁起重机超载运行的四大危害。
桥式起重机电源开关的过载能力不同于低压电器和电动机。因此,应该有较大的安全边际。根据说明书或合同要求,进行试验的桥机,逆变器的长期供电能力应满足试验要求。此类实验包括:72h/168h满载测试、110%负载动载测试等。
横向过载限制器广泛应用于电动起重机。安装方法是:松开限位器细丝,将钢丝绳固定端压入限位器细丝,锁紧钢丝绳微变形器上下细丝,按说明书连接限位器电源。手术。超载限制器的控制线接在桥式起重机起升电路的控制电路上。
桥式起重机逆变器的过载电流能力大于起重机所需的大转矩电流。当电机克服动态负载时,需要变频器的大电流大于大电流。电动机启动时,承受加速力矩、机构专用力矩和规范要求的启动力矩。桥式起重机的变频器需要满足起重机机构的一些特殊要求,如起重机构的过载试验、作业机构现场作业的防风等级等。
安装时应注意两点:一是过载限制器必须安装在电缆的固定端,即钢丝绳已固定好。我们知道桥式起重机的电动葫芦有2根、4根、6根钢丝绳。电动葫芦起吊时,一根或两根钢丝绳不会移动。固定钢丝绳上应安装超载限制器。其次,过载限制器压绳螺丝松紧度应严格按照说明书要求,即钢丝绳轻微变形应拧紧过紧或过松,都会影响使用作用。
