(1) Large waste of resources: In the process of separating the heavy phase from the light phase with a centrifuge, the oil in the light phase will leak from the outlet of the heavy phase, which will easily cause waste of resources;

(2) High cost: If the light phase oil leaked from the heavy phase outlet is separated and recovered for the second time, it will inevitably increase the cost;

(3) Low refining rate: secondary separation and recovery of the light phase oil leaked from the heavy phase outlet, the refining efficiency is low;

(4) A large amount of manual operation: In order to control the frequency of oil leakage during the separation process of the heavy phase and the light phase, it is necessary for the commissioner to stick to his post and conduct inspections and adjustments, which requires a large amount of manual operation;

(5) Inconvenient operation: In the manual inspection and adjustment, the operator's operation is more difficult, and a slight negligence will cause great losses.
