Shaft discharge machine shaft discharge machine energy-saving fan blower

Shaft discharge machine shaft discharge machine is used saving 18.5 ~ 30KW slip motor speed, speed is usually controlled 300-1000rpm, which is based on the case of the kiln, to control the discharge rate of the process. Frequency control method substituted slip motor. After a number of manufacturers of application results show that the average energy savings of about 40 percent, why motor slip frequency transformation we have so much energy savings, because the use of slip speed is a method of inefficient energy transfer speed methods, one, slip motor main motor shaft output power: P0αM0 * N0 P0: indicates shaft output power M0: indicates the load torque N0: 2 represents the main motor speed, slip the first output power: P1αM0 · N1 P1: represents the output power N1: represents the slip head speed 3, slip the first loss of power: △ P = P0-P1αM0 (N0-N1) can be clearly seen by the slippery head loss power equation, slip motor speed The lower, the greater the waste of energy, but unloading the machine speed is usually run at about 400rpm, so there will be 50 to 60% energy saving effect of frequency control mode switch. In addition to the cement plant kiln unloading machine is used slip, motor, there are many devices are using the same slip motor, to further tap the potential to be a comprehensive energy inefficient motor slip frequency transformation, energy outlook promising .
