Yung economic electromechanical more than just specializing in the the leather perforated hollow servo repair business, and 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 by telephone engineers Yung economic solutions will be able to exclude . 1, the leather perforated hollow servo maintenance energy saving principle: the motor hard start to cause a severe impact on the grid, but also the requirements of grid capacity is too high, baffle and valve damage greatly startup current and shocked , extremely detrimental to the life of the equipment, piping. Frequency energy saving device, the soft start function will allow the use of server start-up current from scratch, the maximum value does not exceed the rated current, reducing the impact on power supply capacity requirements, extended equipment and valves life saving equipment maintenance expense. Leather punch the hollow machine servo repair characteristics of the high degree of protection: Power range: three-phase 380 ~~ 460VAC 1.5KW ~ 550KW; high starting torque: zero speed can output 150% rated torque; the high Guozainengli 150 % overload one minute, more than evenly 2 times the rated current of the overcurrent capacity; accurate speed control: speed control accuracy of 0.2%, 0.01% of the output frequency accuracy; precise torque control: torque control accuracy of 5%; higher harmonics wave restrain: 18.5KW and above are built-in DC reactor; maximum output frequency: 400Hz. Has been leather perforated hollow servo maintenance are customers are more concerned about the problem, Yung economic electromechanical years committed to the maintenance of industrial automation products, and always solve the urgent needs of our customers.
