Forward Reverse frequent switching mixer

In order to improve production efficiency, requires shorter process times reversing switch As possible, preferably controlled within 5 seconds . Mixing station drying drum capacity is generally 1t ~ 10t, electricity Machine 18.5KW ~ 55KW power in general between , if you use the direct control of the motor contactor start stop Not only shut down for a long time ,Asphalt Mixing Plant takes about 30 seconds , and the frequent switching and straight forward reverse Then the start and concrete mixing machine  the motor equipment and grid impact are large, so that the device will greatly shorten Service life. In this case , you must use the inverter , and the inverter has the following to Requirements: 1 ) strong overload 2 ) has a two -speed function 3 ) external terminal control 4 ) energy 24 Hours of work 5 ) can quickly reversing switch from positive to reverse the total time of 5 seconds or less.
