The present work aims to study the effect of disk material and disk surface roughness on the oil recovery rate and oil recovery efficiency. Materials used in this study were steel, plastic, and woven fabric; two types of oil were used, namely, SAE50 and used car engine oil. The oil recovery rate was found to increase with increasing disk rotational speed. The rate of oil recovery ranged from 88.19 to 337.14 (mL/min) for SAE50 oil and ranged from 89.03 to 355.4 (mL/ min) for used oil depending on disk rotational speed and the type of disk. The rough steel disk performance is inferior to other disks except at high rotational speeds. Oil recovery efficiency was found to decrease with increasing disk rotational speed. The oil recovery efficiency ranged from 77 to 95.2 for SAE50 oil and ranged from 72 to 95.2 for used oil depending on disk rotational speed and the type of disk. Specific energy consumption ranged from 3.08×10⁻⁴ to 4.7×10⁻⁴ kW·h/kg of recovered SAE50 oil and ranged from 3.04×10⁻⁴ to 2.589×10⁻⁴ kW·h/kg of recovered used oil depending on disk rotational speed.

本工作旨在研究圆盘材料和圆盘表面粗糙度对回油率和回油效率的影响。本研究中使用的材料是钢，塑料和机织织物；使用了两种类型的机油，即SAE50和二手汽车发动机机油。发现油的回收率随着盘转速的增加而增加。SAE50油的回油率范围为88.19至337.14（mL / min），废油的回油率范围为89.03至355.4（mL / min），具体取决于圆盘转速和圆盘类型。除了在高转速下外，粗糙的钢质圆盘性能不如其他圆盘。发现油回收效率随着盘转速的增加而降低。SAE50油的采油效率范围为77至95.2，范围为72至95。2用于废油，具体取决于圆盘转速和圆盘类型。比能耗为3.08×10回收的SAE50油的量为^-4到4.7×10 ^-4 kW·h / kg，根据盘转速，回收的废油的范围为3.04×10 ^-4到2.589×10 ^-4 kW·h / kg。
