Yung economic electromechanical more than just specializing in high frequency welding machine inverter repair business, but also long-term to help provide technical Q & production problems encountered by a lot of equipment in the shop floor, often telephone answer through tolerance economic engineers will be able to exclude . 1, high frequency welding machine inverter maintenance of energy-saving principle: motor hard start to cause a severe impact on the grid, but also high grid capacity requirements, 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 make use of the frequency converter 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 high degree of protection of the high-frequency welding machine inverter maintenance features: power range: three-phase 380 to 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 the high-frequency welding machine inverter repair are the 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.
