Sem The Electric Counterwheight

The electric counterbalance How to minimize the electric consumptions and the cater Ing. Sebastiano Acquaviva - ENCOSYS s.r.l. (Torino-Italy) initiation It is some time that the discussion ab disclose what is the beat out technology for the elevations is open. An essential parameter for this affinity is the energy consumption, or rather the two factors that determine it: the power and the energy. Another authorized parameter for the choice is the speed of the car. set type| hydraulic| Geared| Gearless| Speed| (m/s)| 0.63| 1.0| 1.0| Load| (kg)| 630| 630| 630| go size| (kW)| 11| 5.6| 4| Plant efficiency| %| 60| 65| 80| Counterwheight| | No| Si| Si| Tab. 1 - Plant typology equating Table 1 shows a direct comparison mingled with different types of elevator in accordance with the reliable technology. A first analysis tends to indicate that the gearless technology is the best one.  precisely a closer inspection shows that the difference is driven by two pa rameters: the overall efficiency and the counter cant. Figure 1: auto speed in a basic cycle t td ta td tr td ta td tr td ta T tc The fathom of the efficiency on the energy is evident for any plants. In the case of the geared or gearless elevator the difference of the rousing power is only due to the gearbox efficiency that subdue the overall result. The social movement of the counterweight plays an important rule on the motor size and on the power necessary for the beseeming operation, as well as on the speed. Since the power indispensable is prone by the weight raised times the pilgrimage speed, the presence of the counterweight allows to increase the car speed be with relatively low power. Because The hydraulic elevator, for a correct functioning, needfully to spurt with a high oil pressure, to equip the counterweight for this elevator typology is not convenient. Moreover, only a reduced billet of the weight can be bal anced from the counterweight, then...If you ! want to set forrad a full essay, order it on our website: OrderCustomPaper.com
