In December 2007, the Yuchi independent development of the engine cooling system simulation and pump performance measurement test bench (pump simulation bench) successfully came out. Due to the failure of domestic manufacturers to meet the requirements of Yuchai multi-functional test bench, Yuchai experts put forward a bold assumption in 2006: Yuchai independent design and development of pump simulation test bed. In early 2007, the pump simulation test-bed project team was established. The chief mechanic of the stock company Tan Baixin personally led the team. The project team consisted of experts in manufacturing technology department, technical center, maintenance center and quality department or technical staff. After nearly a year of hard work, in December 2007, the pump simulation bench was finally successful, is now available at the set temperature of the pump or the whole machine (diesel engine assembly) flow, pressure, lift, cavitation and efficiency test. At present, the development team is final debugging gantry, is expected in January 2008 can be formally put into use. Most of the sensors used in the bench use imported parts, all test methods are designed in full accordance with national standards. According to "JB / T8126.1 ~ 8126.2-1999 internal combustion engine cooling water pump industry standards" for performance testing, the results show that the accuracy and stability are much higher than the industry standard, in addition to the installation of pumps and pipes, the entire testing process is based on the edited The program automatically measures, records and stores data with high testing flexibility to fully meet the various requirements of engine cooling testing.
After the infection of the new coronavirus, the human nose, throat, hypopharynx, etc. will be "concurrently carried out". By collecting samples such as sputum of the nose, throat, and throat for human virus detection and testing, it can be determined whether the new coronavirus is worn.
