变频电动葫芦

变频功能型电动葫芦利用变频器使电源频率发生变化，实现电动葫芦起升机构和运行机构的变速，使电动葫芦运行更平稳、定位更准确。该产品具有以下四个特点：1.能减小启动、停止时的冲击，具有平稳运行的性能；2.能按需求设定起升速度，可在1/8额定速度之间随意设定；3.能提高工作效率，在空载下，起升速度可在额定速度到1.5倍额定速度之间设定；4.可以通过变频器对运行电动机进行变频控制，从而使运行电动机微速运行，提高运行定位的准确性，还可以进行点动操作。

Such hoists change the power frequency through transducer and the lifting speed and the traveling speed to make the electric hoist travel more smoothly and more accurately. It has the following four features: 1. reduce starting and stopping impact, travel smoothly; 2. the lifting speed can be designed at random in the range of 1/8 rated speed; 3. to improve work efficiency, the lifting speed with no load can be set at random between the rated speed and 1.5 times the rated speed; 4. to change the frequency of the motor through transducer and make the motor work with slow speed in order to improve its site accurateness.
