Frequency inverter drive for glass tempering furnace blower control

Production processes:
Heating the glass in the furnace before softened, it will be removed to the cooling workshop for fulfilling the process of tempering by quick air cooling, and then blowing the glass continuously until it reaches the normal temperature. When glass is tempering and cooling, another batch of glass is sent to the furnace simultaneously.

Glass Tempering Furnace

Inverter System Configurations:
Cooling blower speed control: open loop vector control frequency inverter.

The standard signal of tempering furnace control system output serves as the setting frequency of frequency inverter drive to control the rotation speed of cooling blower.

Inverter System Features:
1. 120% rated torque acceleration or deceleration, smooth start and acceleration/ deceleration, motor’s current does not exceed the rated current, eliminating the impact on the power grid and equipment.
2. Improve the protection function of motor, and prolong the life span of the motor.
3. Optimize the operational efficiency, and control the rotational speed of cooling blower by the variable frequency drive. The energy saving rate is more than 30%.

Other Applications:

Variable frequency AC drive for air compressor The electric system is consist of variable frequency drive, pressure sensor and other peripheral devices. The start & stop time of the inverter drive can be adjusted randomly (0~10min), means that acceleration when start & deceleration when stop can be adjusted randomly, meanwhile, you can match with S curve ACC/DEC time to start smoothly, which can minimum the impact of air compressor caused by start & stop.

Frequency inverter in construction elevator The whole system consists of PLC, frequency inverter, energy feedback system, electric motor, reduction box, AC input reactor, transformer, operation hand shank etc., to control the start, stop, up going, down going, brake and every kinds of protection of the elevator. The elevator will work at the condition of high-efficiency, safe and stable, meanwhile, the regenerated energy while the elevator going down will be fed back to the power grid to save energy.

Variable frequency drive for CNC machine solution The range of main spindle variable frequency variable speed is very wide, the VFD drive can achieve stepless speed regulation in the range of 0~300Hz, The variable frequency drive matches with CNC machine not only simplify complex mechanical drive mechanisms, such as gearbox, etc, but also make the operation easy & maintenance convenience;
