Water Cooling System

Actuators made of giant magnetostrictive materials (GMM) have good application prospect in the precise driving. Because characteristics of GMM are very sensitive to temperature, the coil thermal effect will cause phenomenon of heat expansion and cold contraction in GMM, which affects the precise displacement output of the actuator. Coil skeleton and water cooling system are installed between the coil and the GMM rod in this design. The effect of water cooling system on the coil temperature rise is experimental studied. It is found that water cooling system can effectively reduce the influence of the coil temperature rise on displacement output of the GMM rod. Water cooling system has greatly improved the coil operating temperature when current is low, while cooling effect is not big for the larger current. That is because the coil heating is strong and the water can not immediately take away the heat. But coil temperature rise is still limited in allowable range. Thus, experiment results show that water cooling system can effectively ensure output precision of the GMM actuator.

Optimal Set

In order to ensure the reliable and safe operation of the electric driving motor of the articulated dump truck, water cooling system is installed for each motor. For the best performance of the water cooling system, not only the heat transfer should be enhanced to maintain the motor in relatively low temperature, but also the pressure drop in the water cooling system should be reduced to save energy by reducing the power consumption of the pump. In this paper, the numerical simulation of the cooling progress is completed and the temperature and pressure field distribution are obtained. The multi-objective optimization model is established which involves the cooling system structure, temperature field distribution and pressure field distribution. To improve the computational efficiency, the surrogate model of the simulation about the cooling process is established based on the Response Surface Methodology (RSM). After the multi-objective optimization, the Pareto optimal set is obtained. The proper design point, which could make the average temperature and pressure drop of the cooling system relative desirable, is chosen from the Pareto optimal set.

Abstract This paper presents an optimal control method for the prediction of parallel centrifugal variable frequency pump performance in any conditions to maximize the total efficiency of the pump system, thereby minimizing energy consumption. First, a theoretical model of parallel water pumping set was established, after which the shaft power model was setup specifically for the off-rating conditions. By combining the typical polynomial fitting method of the efficiency and the shaft power model we brought up, a new optimized control method was proposed. Using this method, the complex optimization task was solved with the optimal control of the operating number selection and speed ratios for parallel variable speed pumps based on the decision-making. The proposed method was subsequently applied to the pumping set of the water-cooling system in High Magnetic Field Facility. The practical testing results of the proposed method showed its superiority over both the primitive and the previous optimal methods, by considerably lowering the power consumption and accurately calculating the performance parameters in any conditions. The method has universality and simplicity for online implementation, which provides a reference for the control methods of parallel centrifugal pumps in variable flow systems with a differential pressure control strategy.
