What is a centrifugal oil filter

Centrifugal oil filter is a filtering device that uses the centrifugal force of high-speed rotation to separate solid particles or droplets suspended in liquid. Its working principle is based on the principle that light, heavy, and solid phases with different densities and immiscibility in a mixed liquid (turbid liquid) can obtain different settling velocities in a centrifugal or gravitational field, achieving the purpose of separating layers or settling solid particles in the liquid. Specifically, when the centrifugal head of a centrifugal oil filter rotates at high speed, the oil, water, and impurities in lubricating oil with different degrees of pollution will be rapidly separated by different centrifugal forces.

Centrifugal oil filters have the following significant characteristics:

• Efficiency: High centrifugal speed, fast filtration speed, can efficiently filter impurities in oil products, saving time.
• High precision: With high filtering accuracy, even impurities smaller than 1um can be removed, which helps extend machine life, reduce wear and parts replacement.
• Economy: The equipment has no consumables, no need for filter cloth cleaning and consumption, and the long-term use cost is relatively low. At the same time, it saves electricity and energy. After starting the power supply, cut off the power supply after adding crude oil, and use the centrifugal force generated by the drum to filter the oil quality.
• Safety: Adopting safety protection devices to ensure that the rotating body will not detach from the motor during high-speed rotation, running smoothly and with high safety performance.
• Wide applicability: Centrifugal oil filters are widely used for the purification treatment of lubricating oil, heavy diesel oil, and edible oil in power plants, ships, large machinery and equipment, as well as oil purification in multiple industries such as metallurgy, mining, petrochemicals, power, and engineering machinery.

However, centrifugal oil filters also have some limitations, such as slightly poorer separation efficiency for oil products with too many impurities. If high impurity accuracy is required, precision filters need to be equipped to filter out impurities. In addition, the installation and maintenance of oil filters may be relatively complex.

In general, centrifugal oil filters are efficient, economical, and safe oil purification equipment, widely used in multiple fields.
