What about the energy efficiency of the escalator
The frequency conversion construction elevator is now basically the mainstream product, the effect is good, the failure rate is low and so on the advantage.
Construction elevator adopts frequency conversion stepless speed, smooth braking, small impact on the grid, and energy saving effect is obvious, ordinary construction elevator running speed is 36 m/min, motor, 3 * 11 kw; Frequency conversion construction elevator running speed can reach at low speed: 0-46 m/min, motor: 2 * 11 kw, whether in theory or in practical construction, energy saving effect is remarkable, some developed coastal areas in frequency conversion construction elevator as mainstream products has become a trend.
Variable frequency construction elevator energy saving effect general. Frequency conversion is not energy efficient. The difference between the frequency and the common machine is the smoothness and speed of the operation. Frequency conversion speeds up to 90m / 1 minutes and the average is only 35m / 1 min Frequency conversion when parking is slow down and stop Ordinary is directly stop delay parking and adjustment made door light who bow Angle decyl with brush spring connection will be better. The frequency conversion requires the site voltage to be strictly a little bit looser than the voltage requirement Energy consumption is: according to the elevator drive mechanism for general three transmission two kinds of the elevator are three 11 kw motor, that their energy consumption are 3 x 11 = 33 kw is hours each hanging basket consumes electricity 33 degrees, the actual power consumption will be bigger.
