Research On Engine Coolant Cavitation Corrosion Test Pump Development And Corrosion Test Bench Reconstruction

The engine coolant of the vehicle oil occupies a larger proportion,its use is second only to automotive lubricants,the annual demand for engine coolant is about several hundred thousand tons.However,at present,the quality of engine coolant in the market varies greatly.With the full implementation of mandatory national standards,more and more manufacturing enterprises and automobile manufacturers are beginning to pay attention to the quality of engine coolant products.Among them,the aluminum pump cavitation corrosion test,simulation using corrosion test and cast aluminum corrosion test are the product of important bench test issues.In order to cope with the requirement of the engine coolant required by the current compulsory national standards,a new cavitation corrosion test pump was developed in this paper.Through its characteristic curve test and cavitation corrosion test,the test results show that the cavitation corrosion test results is good consistency with that of the recommended Buick pump parameters.The test pump developed in this project has stable process performance.The uniformity,reproducibility and batch stability of the same batch of test pumps meet the expected requirements.At the same time,based on the analysis of the existing problems and defects in the corrosion test,three sets of engine coolant corrosion test bench devices were optimized and rebuilt.Developing an aluminum water pump that meets the requirements of the test has been upgraded and rebuilt through the modification of the piping system,heating effect,vibration reduction design and data acquisition system,etc.With good appearance,low noise,low cost,easy operation and good economics the New Engine Coolant Corrosion Bench Test Device was made.Cavitation corrosion of aluminum pumps that enhance engine coolant,simulate the level of detection of corrosion and heat transfer corrosion of cast aluminum alloys,provided support for the regulation of engine coolant products.For our country’s quality inspection agencies,as well as production-oriented enterprises to monitor the quality of their products played a great role in promoting,not only to fill gaps in domestic projects,but also at the leading level in the international position.After the transformation of the equipment is completed,it is estimated that it will bring considerable social and economic benefits each year.
