Power plant energy conservation and emissions reduction

Regardless of the hydraulic coupling in easy maintenance and low price advantage, to a typical 1500 kw induced draft fan speed drive, for example: hydraulic coupling = converter + filter + + air conditioning system lubricating oil station and hydraulic pressure station + gearbox (driven feed pump). Frequency converter function mainly reflects in the speed control link, and hydraulic coupling in the soft start, speed, improve the whole shafting torsional transmission, daily maintenance, etc. All links are trustworthy. Differences in detail are as follows:

1, the price of hydraulic coupling generally by more than 20% lower than the frequency converter () on the basis of power, voltage, higher power converter system only 50-70% of the price.

2, wave produced by the peak torque converter is impossible flexible coupling damage even machine.

3, inverter because by motor directly driving machine, is required to choose than actual motor power of the motor, in order to help realize starting smoothly.

4, inverter output higher order wave will reduce motor efficiency, increase the heat. Need to increase or add a cooling fan for heat dissipation, motor. (heat dissipation function is proportional to the speed of the motor, motor designed to be a constant speed when using hydraulic coupling).
