Conditions and methods
According to the "quantitative" material taking speed regulation, check the boom rotation speed regulation. The speed regulation changes with the material amount on the cantilever belt conveyor by 1/c0s. The rotation speed of the boom when it is detected is 11°, 30°, 50°, and 70°
Inspection tools: Laser speed meter or tachometer. When there is no sunlight, measure with a steel tape measure based on the wheel end face. The tension and measurement correction value of the steel tape measure should comply with the regulations. The span deviation AS is equal to the difference between the actual measured value (corrected according to Appendix C) and the nominal span value. If the actual measured values ​​of the two end faces of a pair of wheels are different, take the average value of the two as the actual span value. 2~3 sets of data should be tested. The S of the two pairs of wheels is subtracted from the actual measured values ​​of S; the relative difference in span is obtained.
Testing tools: pot tape measure, 150N spring scale, ruler caliper
When the machine is working normally , close the doors and windows of the driver's cab, and measure the noise in the driver's cab with a sound level meter at 0.5m in front, back, left and right of the driver's ears when the driver is sitting.
Check the dust emission at the transfer funnel and the end of the pile discharge.
Detection instruments: dust sampler, air dust concentration meter, single-pan photoelectric balance for filter membrane weighing. The measuring point should be 1m vertically away from its shell, measured with a sound level meter.
Measure directly with a paint film thickness gauge in contact with the paint film surface. Generally, 3 main steel structures and 2 general structures are randomly inspected. Each tested piece is inspected at 10 points and the thinnest paint film is taken as the basis for evaluation.
Testing instruments: paint film thickness gauge, contact digital display
