| Abstract:Taking a marine diesel engine as an example, the design method of lubricating oil inlet temperature matching is introduced. The model of thermostatic valve core was established, and the effect of single-row thermostatic valve arrangement, double-row thermostatic valve core arrangement and double-row labyrinth thermostatic valve core arrangement on flow consistency and flow distribution was studied by CFD analysis. The results show that the double row labyrinth thermostatic valve core arrangement meets the design requirements. |
