Embodiment:
Embodiment:
As shown in Figure 1, this is the embodiment of oil sprayer spraying drop point testing apparatus of the present invention, and in figure, oil sprayer is a kind of at right angle setting method, also can install by certain angle.This scheme is by oil sprayer fixing device, fuel collection device, the support device composition of gathering-device.
Described oil sprayer fixing device comprises: pair of supporting 2; Be positioned at the oil sprayer fixed pan 3 on supporting frame, can be along pair of supporting translation, supporting frame end face indicates scale, and direction is designated as directions X; Oil sprayer is fixed vertical plane 4, can be along the slide slot translation in oil sprayer fixed pan, and direction is designated as Y-direction, and slide slot is marked with scale, and Y-direction is vertical with directions X; Be positioned at the circular groove on the fixing vertical plane of oil sprayer, oil sprayer can carry out quantitative angular adjustment along the annular slide slot of fixing vertical plane, and circular groove indicates angle.
Fuel collection device is made up of some compact arranged test tubes; Compact arranged test tube entirety composition regular hexagon; The support device of gathering-device comprises barrel support 1, lifting bucket 9 and is positioned at the fastening screw trip bolt 10 on barrel support, and supporting drum indicates scale, and lifting that can be quantitative, with the fixing a certain position of fastening screw trip bolt.
Before oil sprayer is installed, first fixed fuel gathering-device, is located at the centre of testing apparatus.Test tube is numbered, and as Fig. 2, the present embodiment adopts 127 test tubes, its coding rule; By concentric regular hexagon order, numbering from inside to outside, bosom is numbered 00, with center test tube tangent along regular hexagon arrange test tube by being numbered counterclockwise A1, A2, A3, A4, A5, A6(rightmost is A1), first digit represents that test tube institute is along orthohexagonal numbering above, after the sequence number of test tube on this regular hexagon of digitized representation.By that analogy, on second regular hexagon, test tube is numbered B1, B2, B3, B4, B5, B6, B7, B8, B9, B10, B11, B12.By this rule, all test tubes have corresponding numbering.Because test tube size is known, this programme test tube is of a size of external diameter 8mm, and internal diameter 6mm, according to the geometrical relationship between each test tube center of circle, can determine the position of each test tube center on plane coordinate.Take middle row as a axle, be b axle by center drum center and the line vertical with a axle, A1 coordinate is [8, 0], A2 coordinate is [4, 8], A3 coordinate is [4, 8], A4 coordinate is [8, 0], A5 coordinate is [4,-8], A6 coordinate is [4,-8], B1 correspondence [16, 0], B2 correspondence [12, 8], B3 correspondence [8, 16], B4 correspondence [0, 16], B5 correspondence [8, 16], B6 correspondence [12, 8], B7 correspondence [16, 0], B8 correspondence [12,-8], B9 correspondence [8,-16], B10 correspondence [0,-16], B11 correspondence [8,-16], B12 correspondence [12,-8], analogize in proper order the coordinate that can determine all numbering test tubes.
After being numbered, claim the quality of each numbering test tube with electronic balance scale, write down the quality of corresponding test tube.
Oil sprayer is installed, if the oil sprayer in reality is to tilt to install, in the present invention, along supporting frame top slide oil sprayer fixed pan 3, move the fixing vertical plane 4 of oil sprayer along the slide slot of oil sprayer fixed pan, annular slide slot in the fixing vertical plane of oil sprayer rotates oil sprayer, by the above position of quantitative adjusting, makes the installation of oil sprayer approach the installation situation in reality.
After oil sprayer installs, adjust the fuel collection device distance apart from oil sprayer, the lifting of the support device by gathering-device reaches our desired distance, then uses set screw fixed position.
After more than adjusting, give oil sprayer fuel feeding, in order to reduce error, make its continuous injection 500 times, fuel oil drops on below in vitro; After oil sprayer has sprayed, then weigh up the quality of each numbering test tube with electronic balance scale.Write down the quality of reference numeral test tube; Twice quality record before and after the test tube of each numbering asked to poor, draw the fuel oil quality that each test tube is collected, then average, calculate the drop point quality that each injection test tube is collected.Can draw the distribution map in the plane of drop point with related software.
Drop on the position of outmost turns according to spraying, the present invention can calculate, and collects the spray cone angle of plane separation oil sprayer distance, by formula θ=2arctan(d/h) calculate, wherein, d be edge in the plane of spraying far from center distance farthest, h is the perpendicular distance of oil sprayer anomaly face.
By above embodiment, can measure the spray cone angle under spraying distribution and certain penetration distance of this oil sprayer.Certainly, some devices in this oil sprayer spraying drop point testing apparatus can be changed, and as less in test tube size, the precision of its test is higher.
