Abstract: To improve the spraying quality of vehicle-mounted sprayer for liquid deicing and snow-melting agent, the influences of the fluctuations of the vehicle speed and the agent pump speed on the spraying quality are discussed. A pump speed control system is proposed under the condition of varying vehicle speed with the help of theoretical analysis and field test. Experiment results show that, when the vehicle speed is slower than a critical value, the pump speed maintains the threshold and the actual spraying volume deviates from the target value, but there is no striped spraying defect. If the vehicle speed exceeds the critical value, the pump speed would be automatically adjusted by the control system according to the vehicle speed and the actual spraying volume is close to the target value.

Key words: road engineering, liquid deicing and snow-melting agent, sprayer, spraying quality, uniformity coefficient
