This paper designs a measurement system of energy consumption for clothes model controlled by robot technology, the system uses DC motor regulated by PWM regulator to drive the worm wheel reducer and the sinusoidal mechanism, then to drive the robot legs to swing forward and backward in sinusoidal step. The sensors detect the rotation speed and torque of the sinusoidal mechanism, the power and energy consumption. The experiments show the system is high in accuracy, excellent in repetition, and suitable for the further research on the principle and evaluation system of the clothes energy consumption.

Set Up

The exergy consumption during the transportation of heated oil includes four items: valid and invalid pressure exergy consumption, valid and invalid heat exergy consumption. These four parts are taken as the same loss in traditional evaluation systems of pipeline energy consumption, which somewhat hinders the further energy-conservation study. So establishing a scientific exergy consumption evaluation system is an important basis work of energy efficiency management. Based on the index system of energy efficiency for pipeline proposed by predecessors, the meaning of energy quality for exergy and the categories of exergy flow, the energy consumption index set of exergy transfer is set up in this article. Moreover, by computing exergy consumption index of exergy transfer for an oil pipeline in Daqing Oilfield, a part of representative indexes are selected by analyzing the obtained data with correlation coefficient method. Finally, the exergy consumption evaluation system is constructed.

Power And Energy

The boom with closed circuit in Hydraulic Excavators, which is made up of motor, hydraulic pump and accumulator, was put forward based on analysis of the operating condition of ordinary hydraulic excavators and mathematical models of system were built. Power characteristics of main power elements were obtained under typical operating conditions, and then the energy consumption characteristics were analyzed. The results show that the installed power and energy consumption will be reduced using boom with closed circuit, and no-load drop and full load rise of boom are the worst operating conditions.

Abstract The bucket wheel excavator (BWE) is a continuous working rock harvesting device which removes the rock by means of buckets armoured with teeth, mounted on the wheel and which transfers rock on a main hauling system (generally a belt conveyor). The wheel rotates in a vertical plane and swings in the horizontal plane and raised / descended in the vertical plane by a boom. In this paper we propose a graphical-numerical method in order to calculate the power and energy requirements of the main harvesting structure (the bucket wheel) of the BWE. This approach - based on virtual models of the main working units of bucket wheel excavators and their working processes - is more convenient than those based on analytical formulas and simplification hypotheses, and leads to improved operation, reduced energy consumption, increased productivity and optimal use of available actuating power.
