Detailed Description
Example 1
As shown in fig. 1 to 4, the present embodiment provides an apparatus for testing overall performance of an atomizing nozzle, wherein a telescopic hydraulic prop 21 is fixedly connected to the base 1 perpendicularly to the base 1, and the position of the atomizing nozzle 3 in the vertical direction can be adjusted by controlling the telescopic hydraulic prop 21 to extend and retract. The water collecting pipe bundle 4 and the pressure tester 5 are respectively fixedly arranged on the base 1 and are positioned at the left side and the right side of the telescopic hydraulic prop 21. Specifically, a water pan 52 is arranged on the base 1, and a pressure tester 5 is arranged in the water pan 52. During the process of spraying the atomizing nozzle 3 to the pressure tester 5, the sprayed water drops splash into the water pan 52. The upper end of the telescopic hydraulic prop 21 is rotatably connected with one end of the horizontal rod 22, and a positioning bolt 26 is arranged between the upper end of the telescopic hydraulic prop 21 and the horizontal rod 22. After the spray nozzle 3 performs a spray test on the header pipe bundle 4, the horizontal rod 22 is rotated by 180 °, and after the spray nozzle 3 is moved to a proper position above the pressure tester 5, the rotation of the horizontal rod 22 is locked by the positioning pin 26.
The other end of the horizontal rod 22 is rotatably connected with a suspender 23, and a positioning bolt 26 is arranged between the horizontal rod 22 and the suspender 23. The lower end of the suspender 23 is fixedly connected with a water spraying disc 24, and a plurality of water supply connectors 25 are arranged at the edge of the water spraying disc 24 at equal intervals. One side of the water supply joint 25 is connected with a high pressure water source through a water supply pipeline, and the other side of the water supply joint 25 is detachably connected with the atomizing nozzle 3. The rotation of the water spraying disc 24 and the locking suspender 23 through the positioning bolt 26 is rotated, the plurality of atomizing nozzles 3 on the water spraying disc 24 enable one atomizing nozzle 3 to be over against the central position of the water collecting pipe bundle 4 and the pressure tester 5 during each test, and the water spraying disc 24 is rotated and fixed by the positioning bolt 26 during the next test, so that the next atomizing nozzle 3 is over against the central position of the water collecting pipe bundle 4 and the pressure tester 5.
A water collecting pipe bundle 4 formed by splicing a plurality of water collecting pipes 41 is arranged below the water spraying disc 24, and a water level detector is arranged in each water collecting pipe 41. In this embodiment, the water level detector is an infrared detector 42, and the infrared detector 42 is disposed at the upper end of the water collecting pipe 41. The fog drops sprayed by the atomizing nozzles 3 enter the water collecting pipes 41, the infrared detectors 42 detect the liquid level height in the water collecting pipes 41 and upload the liquid level height data to the computer 8, and the computer 8 processes and calculates the water amount in each water collecting pipe 41, so that the spray flow distribution of the atomizing nozzles 3 is determined. It should be noted that the liquid level in the water collecting pipe 41 only needs to determine the values before and after the test, and the computer 8 processes and calculates the amount of the water change in each water collecting pipe 41 during each test, so that the water in the water collecting pipe 41 does not need to be tilted before each test, and the test operation is convenient.
A pressure tester 5 is arranged below the water spraying disc 24, a plurality of pressure sensing modules 51 are uniformly arranged on the pressure tester 5, and pressure sensors are arranged in the pressure sensing modules 51. Specifically, the pressure tester 5 is a cone structure, and a plurality of pressure sensing modules 51 are uniformly arranged on the side surface of the cone structure. The atomizing nozzle 3 sprays to the pressure tester 5, each pressure sensing module 51 on the pressure tester 5 senses impact pressure and uploads pressure data to the computer 8, and the computer 8 processes and calculates to obtain the distribution condition of the water flow impact force sprayed by the atomizing nozzle 3.
A high-speed camera 6 and a laser Doppler measuring instrument 7 are arranged at the horizontal position opposite to the atomizing nozzle 3. The high speed camera 6 captures an image of the water stream sprayed by the atomizing nozzle 3 and uploads the image to the computer 8 to determine the atomizing angle of the water stream sprayed by the atomizing nozzle 3. And the laser Doppler measuring instrument 7 is used for testing the particle size and the speed of the fog drops sprayed by the atomizing nozzle 3 and uploading the data to the computer 8 for analysis and processing.
The water level detector, the pressure sensing module 51, the high-speed camera 6 and the laser Doppler measuring instrument 7 are respectively connected with the computer 8 through signal cables 9.

After the spray nozzle 3 has performed a spray test on the manifold bundle 4, the rotation lever 54 is rotated to rotate the pressure tester 5 above the manifold bundle 4, and the rotation of the rotation lever 54 is locked with the positioning pin 26. In the process that the atomizing nozzle 3 sprays the pressure tester 5, the sprayed water drops splash into the water collecting pipe bundle 4, the water collecting tray 52 is omitted, the device structure is simplified, and the detection of the liquid level in the water collecting pipe 41 by the infrared detector 42 in the water collecting pipe 41 is not influenced.
