在离心甩油盘性能试验器上对一种离心甩油盘雾化性能进行了较详细的试验研究,用相位多普勒粒子分析仪(PDPA)测量了不同转速下甩油盘的燃油雾化粒度索太尔平均直径(SMD)、雾化锥角等性能参数.试验结果表明:在试验转速范围内,随甩油盘转速增大,甩油盘雾化锥角α逐渐减少;随甩油盘转速增大,雾化粒度SMD值逐渐减少,当甩油盘转速大于25 000r/min时,燃油的SMD值基本保持不变;在同一甩油盘转速下,燃油的SMD值随离甩油盘喷油孔距离的增大而增大.
In the centrifuge rejection oil pan performance tester for a centrifugal oil thrown off the performance of the oil tray conducted a more detailed study of the use of phase doppler particle analyzer (PDPA) measured at different speeds of the oil pan oil spatter Particle size Soybey mean diameter (SMD), atomizer cone angle and other performance parameters.Experimental results show that: with the increase of rotating speed of the oil pan, When the rotating speed of the oil pan is more than 25 000r / min, the SMD value of the fuel basically remains unchanged; at the same speed of the oil pan, the SMD value of the fuel decreases with the oil rejection Disk injection hole increases the distance increases.
