The invention discloses a normal-pressure spraying test table. The normal-pressure spraying test table is composed of a
nozzle adjusting table, a test
bed frame, a collecting table, a
ball screw sliding table and an air extraction device from top to bottom in sequence; the
nozzle adjusting table is fixed on the side edge of the test
bed frame; the collecting table is embedded into the test
bed frame, and a lead screw sliding block is arranged at the bottom of the collecting table and is connected with the
ball screw sliding table; and the air extraction device is arranged below the collectingtable. According to the normal-pressure spraying test table, multidirectional movement of a
nozzle in three-dimensional space can be realized, the test table is applicable to detection of different spraying injectors, and the
automatic control of the spraying amount and the spraying position is realized; meanwhile, the overall structure is optimized, the splashing of liquid drops is reduced to themaximum, the
liquid drop measuring precision is improved, and the experiment efficiency is improved; and in addition, the normal-pressure spraying test table is simple in structure, low in cost, convenient to install and convenient in part replacement and maintenance.
