We have set up an atomizing nozzle test center. Covering a land area of 600 m2, the center boasts its own air compression station and water pump station. The test items include pressure and flow characteristics, angles, water distribution, spray droplet, impact force, thermal cooling and etc. The test data are collected automatically by computers. The center is in the leading position home and abroad in terms of test precision and range.

The test system mainly consists of the air and water loops, the air pressure sensors, water pressure sensors, flow rate sensors and temperature sensors. It collects handles and tests the liquid levels and the spraying angles through pipes and sensors and computers and finally prints the charts.

The simulation test bed can be fitted with several atomizing nozzles to simulate the actual working condition in the test. In this way, it tests the actual water distribution of the time, and meanwhile makes adjustment to the space between the nozzles and the height of spray to achieve the more applicable scheme for the arrangement of nozzles and make the atomizing nozzles more effectively used.

This device simulates the practical working condition of high-pressure nozzle and passes signals through the sensors of pressure, flux and distance. The computer timely collects, processes and detects the wallops ,flux and spray angles in correspondent pressure and prints them out in the form of chart.

There are different requirements in practical use to the sizes of atomizing spray droplet made by the nozzle. To conduct further research on the sizes of atomizing spray droplet, we configure spray droplet laser detecting system. The laser beans sent by laser tubes travel through the atomizing section of the detected nozzle and are received by the probe on the sink. The computer timely collects, processes and detects the sizes of the atomizing spray droplet and prints out charts.

Spraying impact force of the nozzles directly affects the cooling efficiency of the working condition. This device simulates the practical working condition of low-pressure, flow rate and distance. The computer timely collects, processes and detects the impact forces at different points in the spraying area and prints them out in the form of charts.

To effectively master the performance properties of the nozzle in thermal state, the system, equipped with heating furnaces and thermocouple probes, simulates the on-the-spot working condition, detects the cooling trend of the spray to get the heat transfer coefficients of the nozzle cooling processed by computers and prints them out in the form of charts.
