                                        EGR冷卻器性能測試系統簡介

                                        2017-01-04 0

                                        EGR冷卻器性能測試系統適用于測試冷卻器的換熱性能及耐久性,為冷卻器的設計提供試驗數據。本測試系統由燃燒系統、加熱系統、冷卻器安裝臺、氣路連接系統、冷卻液循環系統、控制系統組成。可完成以下試驗:1、熱性能試驗:測試不同工況下冷卻器換熱效率、流場阻力大小;2、冷熱沖擊試驗:測試極端溫度和流量變化情況下對冷卻器綜合性能的影響;在EGR冷卻器氣側通入設定流量、溫度和壓力的空氣,水側通入設定流量、溫度和壓力的冷卻液,同時分別測量氣側和水側的進口壓力、進出口壓差、進出口溫度和進口流量。 

                                        EGR冷卻器性能測試系統主要參數如下:(參數范圍外請咨詢,電話:0755-8889 8859  QQ:459675648)
