The induced draft fan of desulfurization system in the new project of a zinc smelting enterprise in Yunnan is driven by a 6kV / 800kW high-voltage motor, the load has a very important role in the process, once the problem occurs, it will cause environmental pollution, due to the numerous dust on site, So the stability requirements to the inverter are higher, in the operation process, the wind pressure is needed to be adjusted in real time according to the working conditions. Taking the energy saving, stability and other factors into account, the company finally selects our company’s inverter for the project construction.
In this paper，through introducing INVT Goodrive5000 medium voltage VFD applied to sugar mill house mill presser in Pakistan, especially to illustrate many benefits of VFD and AC motor system instead of steam turbine system. Which is an important technical improvement and use VFD and AC motor is good for production automation and decrease user cost of production.
This paper mainly presents INVT CHV110 series inverter used for injection moulding machine in India. It gives the detailed solution for old injection moulding machine retrofitting to save energy. Engineering practice shows that INVT CHV110 series inverter has good performance and stability on injection moulding machine.
The carding machine works by opening individual fibers and eliminating impurities of the cotton rolls or the chemical fiber fed by the hopper or the former working process, thus straightening the curly cotton rolls while removing the neps, impurities and short fibers left by the blowing process, and then store the integrated slivers into the cotton cylinder to be used in the drawing process.
This paper mainly presents INVT GD20 series inverter used for conveyor (Treadmill), application in Gym and hospital in India. It introduced the process and application of treadmill application, and gives the detailed drive configuration.
"Solution using CHV160A inverter provided by DAT meets technology for pressure system of Thien Hung Textile Company. The inverter ensures the output pressure is stable, the equipment is durable, save 10% of electricity consumption and easy to check, calibrate and operate. "
GD5000 inverter supplied by DAT meets the requirements of technology, resulting in great power saving efficiency for Hoa Phat Steel JSC. The use of fan speed control in the production process, which helps us save up to 40% of power consumption compared to before.
