At present,the energy efficiency evaluation of centrifugal pump units in China is still in the exploratory stage.In order to evaluate the energy efficiency level of the equipment quickly and accurately,based on the MVC model of the .NET platform,this paper designs and develops an automated evaluation system. On the basis of establishing the mathematical model of energy efficiency evaluation of pump units,the parameters are collected and processed. The data is imported manually or by accessing the database，and the energy efficiency calculation is performed according to the standard using a simple and highly accurate formula. The system is applied to verify the example，and the operating condition of the equipment is compared with the economic operation discriminate table to judge the operation of the unit. The results show that the evaluation results calculated by the software are accurate.Without complicated manual calculation,the evaluation time can be shortened,the work efficiency can be improved，and it has certain application value for industrial production.

The energy consumption evaluation indexes of fan units and pipe network system are obtained by referring to national standards and setting up a subtarget set of energy consumption evaluation,AHP analytic hierarchy process was used to analyze and compare the factors affecting energy consumption, and EXCEL software was used to deal with them. The influence degree of each factor on energy consumption was obtained, namely the weight of each factor.Using fuzzy mathematics,combining with the weight of all the factors obtained,evaluate the energy consumption for fan unit and pipe network system.Verified by examples,the system is in excellent condition,and it is consistent with the actual situation.

In tertiary recovery process, there was a need of the static mixer promoting the polymer solution mixed with water to drive oil. Therefore, the mixing efficiency of the static mixer had an important influence on the efficiency of oil production. Based on that the mixing efficiency of the current commonly used static mixer was not high enough, a new type static mixer was developed. The flow characteristics of the fluid in the mixer were studied by the numerical simulation, and the simulation results were verified by the experiments and the performance of the mixer was measured. The result showed that the results of the simulation and experimental were in good agreement; the new type static mixer had the high mixing efficiency and mixing effect; the pressure drop of the static mixer met the requirement, and the best inlet rate was about 0.14 m/s
