Recently, the Technical Department of Hope Deepblue launched a test study on the impact of multiple spray holes at the inlet of the large unit sprayer device on the uniformity of the liquid discharge from the device. In view of the spray uniformity test, the engineers firstly carried out a comprehensive and systematic analysis of the influencing factors of the test and made a prediction of the possible results. After repeated discussions among engineers, the test program was finally determined. After the program was ready, some unexpected and uncontrollable factors appeared in the process of the test, such as unstable water pressure, unable to achieve the design conditions; water storage device with limited water storage capacity, it is difficult to support a long time test and a series of problems. However, in the face of difficulties, colleagues of the Technical Department were not afraid to rise to the challenge and give full play to their initiative to find ways to solve the problems. The test simulated the real generator dripping situation, the water flow was extremely high, and the shoes and socks of the colleagues were completely wet during the test, but they did not care about it and focused on the water measurement, and finally completed the test successfully. This test demonstrated the meticulous and rigorous attitude of the Technical Department in terms of unit performance. At the same time, this test is the result of the joint cooperation between the technical department, the quality control department and the production department. The unity of the company and the cooperation of all departments will lead us to a more brilliant future. We believe that under the guidance of this spirit, Hope Deepblue will continue to climb new heights and provide customers with better quality and more reliable products and services.
