About the electric hoist speed adjustment, a lot of people think the use of inverter is the best method, but you may not know that some electric hoist is the use of inverter, following Shan Yan introduced different methods according to different speed electric hoist.
1, through the frequency converter speed control is the most ideal variable frequency speed regulation method, can realize stepless speed regulation, also has a high control accuracy, can be remote operation, easy to use and maintenance. But it is important to note that using a conical motor electric hoist the general use of inverter, because all inverter starts when the need to speed up the time, when accelerating voltage is slowly rising, the moment can not make shift conical rotor brake release, easy to cause the inverter overload protection.
2, motor rotor resistance speed regulation, its advantage is simple structure, low price, quality in general, its deficiency is the speed change is relatively large, unstable.
3, the hydraulic push rod speed, can achieve a stable speed, but the speed is low, intermediate tecshare soft, and must carry on the transformation of the electric hoist machinery parts when in use.
4, through the power brake speed regulation method, is characterized by the speed of the gear can be adjusted, and high energy saving, safe and reliable use, the disadvantage lies in the grasp of the low speed.
The daily use of electric hoist in the process, the speed of the electric hoist directly affects the efficiency of the construction machinery production, Yan Yan group to remind you to choose the appropriate speed control method based on different electric hoist.
