Yung economic electromechanical not only specializes in the repair business leather polishing machine DC governor, also help long-term production of the user to provide technical advice, the problems encountered by a lot of equipment in the shop floor, often telephone answer through tolerance economic engineers will be able to excluded. 1, Leather polishing machine DC governor maintenance of energy-saving principle: motor hard start to cause a severe impact on the grid, but also the requirements of grid capacity is too high, the startup current and shocked when the damage of the baffle and the valve extremely detrimental to the life of the equipment, piping. Frequency energy saving device, the soft-start function will allow the governor to start the current from scratch, and the maximum value does not exceed the rated current, reducing the impact on power supply capacity requirements, extended equipment and valves the life of, saving the expense of equipment maintenance. High degree of protection of leather polishing machine DC governor maintenance characteristics: power range: three-phase 380 to 460VAC 1.5KW ~ 550KW; high starting torque will be able to output 150% rated torque: zero speed; high overload capacity 150% overload one minute, more than evenly 2 times the rated current over current capacity; accurate speed control: speed control accuracy up to 0.2%, 0.01% of the output frequency accuracy; precise torque control: torque control accuracy of 5%; higher order the harmonic restrain: 18.5KW and above are built-in DC reactor; maximum output frequency: 400Hz. Has been, Leather polishing machine DC governor repairs are issues of concern to each customer, Yung economic electromechanical committed to the maintenance of industrial automation products for many years, always address the urgent needs of customers.
