STUDY ON ENERGY CONSUMPTION CHARACTERISTICS OF VVVF CONTROLLED HYDRAULIC ELEVATORS WITH PRESSURE ACCUMULATORS

Abstract

Abstract: The energy-saving principle of VVVF controlled hydraulic elevators with pressure accumulators is introduced. The calculating method of installed power of the improved hydraulic elevator is presented, and so it is clear that the installed power of the system can be reduced greatly. The experimental power characteristics of the elevator hydraulic circuits are obtained under different working conditions. Compared with other typical hydraulic elevator power systems, this improved system has higher overall efficiency and lower energy consumption.

Key words: Energy consumption, Hydraulic elevators, Installed power, Pressure accumulators, Variable voltage varible frequency
