在罐笼提升时,一般使用手动控制能耗制动。假设预期的速度能以控制手柄的方位给出,而达到所需速度的变化过程,又能按时间进行程控的话,那么司机的操作可以大大简化。由于这种情况可以保证主减速系统处于最佳状态,正如试验结果指出的那样,提升机的装载能力获得了某些增大。此能耗制动系统(见图)是由速度整定环节、阶梯信号转换器ЭИ及以单相半控硅整流器供电的速度自动调节系统CAP所组成。提升机在电动机状态下运行的时间内,能耗制动继电器РДТ与密封接触式继电器РГТ接通,在ЭИ输入端即出现了由测速发电机ТГ输入的速度反馈信号VД,而且在加
In cage promotion, the general use of manual control of energy braking. Assuming that the expected speed can be given in the direction of the control handle to achieve the desired speed change and program control over time, then the driver’s operation can be greatly simplified. Since this situation ensures that the main reduction system is in the best condition, as the test results indicate, the lift capacity is somewhat increased. The energy consumption braking system (see photo) is composed of speed setting, step signal converter ЭИ and automatic speed regulation system CAP powered by single-phase semi-controlled silicon rectifier. During the time when the hoist is running in the motor state, the energy-consuming brake relay РДТ is connected to the hermetic contact relay РГТ, a speed feedback signal VД input by the tachogenerator ТГ appears at the ЭИ input,
