Contributing to energy conservation and environmental protection – uncovering the applications of dual-centrifugal oil mist recovery systems in machine pump lubrication systems! Oil mist lubrication, as a new type of centralized lubrication method, has been widely adopted in various petrochemical and refining industries. Compared to traditional lubrication methods, although oil mist lubrication has many unique advantages, in recent years **environmental regulations have become increasingly strict. The issue of recovering and handling the excess oil mist generated by oil mist lubrication systems poses serious challenges, prompting a focus on energy conservation and environmental protection. Since most of the oil mist particles emitted by oil mist lubrication systems are below 1 μm, it is quite challenging to achieve both high recovery rates of oil and low emissions of exhaust gases. The suction-type and filtration-type oil mist recovery systems commonly available on the market cannot meet such requirements; therefore, centrifugal separation-based oil mist recovery systems have attracted significant attention due to their high efficiency in oil recovery, low concentration of oil mist emissions, and excellent economic benefits. Analysis of the key technical aspects of the dual-centrifugal oil mist recovery system: 1. Zero-pressure difference for balance maintenance ； 2. Dual centrifugal recovery ； 3. Three-filter emission protection ； The dual-centrifugal separation oil mist recovery system is a highly efficient mechanical oil mist recovery device designed based on the principles of centrifugal impact and self-circulation. The residual mist is directed through recovery pipelines into the oil mist recovery main unit under a \"zero pressure difference\" condition. This zero pressure difference ensures that exactly as much residual mist as is generated is processed, preventing excessive or insufficient extraction that could disrupt the normal oil mist pressure in the pump chamber and affect the lubrication effect provided by the oil mist. Driven by the motor, the hub rotates at high speed, creating a negative pressure that draws oil mist particles into the hub. These particles collide continuously with the blades, coalescing into oil droplets. Under the effect of centrifugal force, these oil droplets pass through the pores in the fiber filter and move toward the inner wall of the housing, where they form larger oil drops that eventually flow back into the oil tank ； The gas rises, passes through the sound-dampening filter pad at the top; part of it is sent to the next stage of oil mist collector, while the other part returns to inside the hub for secondary centrifugal separation. The secondary oil collection collector further processes the mist that has undergone primary treatment, and ultimately releases the clean air through the outlet. In summary, with the dual-centrifugal oil mist recovery system, the recovery rate of residual mist lubricant is ≥90%, and the oil mist emission concentration is ≤0.5mg/m3, making it both energy-efficient and environmentally friendly.
