Metal mining electric locomotive factory cheap stock, has been producing frequency conversion motor vehicle warranty for two years, production and sales of variable frequency motor vehicles, 30 tons of the most professional frequency conversion motor vehicle manufacturers want to buy one of the best! The best! Most of the best! Mine locomotive power it? You've come to Jining it vigorously. Mine Electric Locomotive product is our flagship product, the price is most favorable industry which, Jining vigorously will provide you with quality service, high quality products, allowing you to buy rest assured that with liking. How it works: Wired DC550V withstand pantograph grid supply drive, the drive will be needed to reverse into a DC motor three-phase AC, three-phase AC-driven three-phase AC traction motors running, through the gear reducer, drive shafts and other drive locomotive traveling. CJY30 / 7GP main technical parameters: sticky rated voltage V 550 t 30-hour clock hour speed traction kN 60 km / h 12.73 hour power kW 110 × 2 maximum speed km / h 20 gauge Wheelbase mm 900 mm 2500 Minimum curve Gearbox radius mm 30 mm ≥90 surface height from the rail wheel rolling circle diameter hook height mm 780 mm Φ840 gear ratio 11.188 length × width × height mm 7900 × 2050 × 1900 Frequency control braking mechanical brake, electrical brake, air brake CJY30 / 9G (P) frame linear motor car adopts the international advanced VVVF AC VVVF technology, wired DC power IGBT components through adjustable frequency inverter for three-phase AC driving three-phase asynchronous motor as the locomotive power, the use of VVVF control technology, the three-phase asynchronous motors meet and exceed the DC motor starting torque and traction characteristics, so powerful locomotive with a heavy start. It compares with the traditional DC locomotive with AC motor easily damaged, contact the Division controller no no wear, mechanical energy into electrical energy during braking and can feedback. Mine Electric Locomotive advanced technology, innovative design, driving comfort, safety and reliability, energy saving.
