INVT worked with this company since 2010; there are more than 40 sets of INVT medium voltage VFD drives are being used in different applications. Exhaust fan Fans, ID fans, Boiler Pumps, VRM, ball mills etc.
INVT GD5000 medium voltage inverter applied to exhaust fan in the cement factory in Myanmar, to illustrate VFD transformation of the feasibility and many advantages after using MV inverter especially the significant energy saving.
the application of INVT GD5000 medium-voltage inverters to vertical raw mill and describes detailed information involving the process of cement production, control structure and principle of electrical system, and the process of control system commissioning.
the application of INVT CHV100 medium-voltage inverters to rotary kiln and describes detailed information involving the process of cement production, control structure and principle of electrical system, and the process of control system commissioning.
INVT GD5000 medium voltage inverter applied to vertical roller mill in the Pakistan, in order to illustrate VFD transformation of the feasibility and economy. Especially it can increase raw milling production, input power factor and other benefits.
A Tibetan building materials company located in more than 3700km above sea level plateau, the kiln tail hot fan in the production line is driven by a 10kV/2800kW asynchronous motor, The fan air flow is mainly regulated by the hydraulic coupler with low energy transfer efficiency and serious waste. Hydraulic coupler and other auxiliary speed control device contain many failure points and large maintaining works. In addition, the irregular "collapse" in cement production process may cause high temperature fan load suddenly increasing, which will cause the trip and lead to shutdowns.
Electronic cam (abbreviation ECAM) utilizes the constructed cam curves to simulate the mechanical cam to meet the relative motion software system between main shaft and camshaft system the same to mechanical cam system, and feedback the position information to CPU via encoder; the CPU conducts the calculating and processing, and outputs the specified location.
