Yung economic electromechanical more than just specializing in plastic welder servo repair business, but also long-term to help provide technical Q & production problems encountered by a lot of equipment in the shop floor, often by telephone engineer Yung economic solutions will be able to exclude. 1, plastic welder servo repair the energy-saving principle: 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, The service life of the equipment, piping is extremely unfavorable. 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. 2, the the Plastic Welder 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; high overload capacity 150% overload when one minute over current capacity of more than 2 times the rated current of the uniform; accurate speed control: speed control accuracy of 0.2%, the output frequency accuracy of 0.01%; precise torque control: torque control accuracy of 5%; high harmonic restrain : 18.5KW and above are built-in DC reactor; maximum output frequency: 400Hz. Has been plastic welder servo maintenance are various customers are more concerned Yung economic electromechanical committed to the maintenance of industrial automation products for many years, always address the urgent needs of customers.
