About product

The KYDB304 Type Marine Oil Centrifuge is a high-speed oil water separator designed for both offshore and terrestrial applications. Its primary function is to remove water and solid particles, commonly referred to as sludge, from mineral oil. The centrifuge operates at high speeds to effectively separate the impurities from the oil. Clean oil is discharged continuously, ensuring a consistent supply of purified oil for various applications. On the other hand, the dirty residue, containing the separated water and solid particles, is discharged intermittently. This intermittent discharge allows for efficient removal of the accumulated sludge, ensuring optimal performance and longevity of the equipment.

Product Detail

Marine Oil Centrifuge Machine – KYDB304

The KYDB304 Type oil centrifuge machine is a versatile equipment designed to handle various types of lubricating oil and low-viscosity fuel oil. It is capable of processing light oil with a viscosity range of 1.5-5.5est/40℃, marine diesel oil with a viscosity of 13cst/40℃, and intermediate to heavy fuel oil with a viscosity range of 30-380CST/50℃. It can also handle diesel engine or turbine lubricating oil.

This oil centrifuge machine serves dual purposes as both a purifier and a clarifying machine. When used as a purifier, it continuously removes separated water from the oil and discharges it separately. This ensures the continuous purification of the oil, particularly when higher water content is present. However, in cases where the oil contains only a small amount of water, the separator can be used solely as a clarifying machine. In such instances, both the water and warning signals are discharged intermittently, optimizing the separation process based on the specific requirements of the oil being processed.

Marine Oil Centrifuge Drawing – KYDB304 Type

The Marine Oil Centrifuge consists of several main components that contribute to its operation and functionality. Here are the main components along with their corresponding inlet and outlet points:

A) Motor: Provides power for the centrifuge’s operation.
B) Vertical Shaft: Connects the motor to the separation cylinder, transferring rotational motion.
C) Separation Cylinder: Where oil, water, and sludge separation occurs.
D) Flat Belt: Transmits power from the motor to the vertical shaft, enabling cylinder rotation.
E) Closing Water Tank: Contains water for sealing and maintaining separation efficiency.

Inlet and Outlet Points:
201) Oil Inlet: Entry point for oil to be processed.
220) Oil Outlet: Discharges clean, separated oil.
221, 222) Water/Sludge Outlet: Discharges separated water and sludge.
372) Opening Water Inlet: Inlet for water used to open and flush the separation cylinder.
373) Separation Cylinder Closing Water: Inlet for water used to seal and close the separation cylinder.
377) Overflow Port: Discharges excess fluid if the cylinder becomes overloaded.
462) Discharge Port: Used for specific component or material discharge.
463) Discharge Port: Another port for specific component or material discharge.

How Does The Waste Oil Filter System Work On Ship?

The waste oil filter system on a ship, utilizing an oil centrifuge machine, works to separate impurities and contaminants from the waste oil. Here’s a step-by-step explanation of how the system operates:

  • Collection and Pre-treatment: Waste oil generated on the ship, such as used lubricating oil or other types of oils, is collected and stored in a designated tank. Prior to entering the centrifuge, the waste oil undergoes pre-treatment processes to remove larger debris, sludge, or water content. This can involve settling tanks or other separation mechanisms.
  • Centrifugal Separation: The waste oil is fed into the oil centrifuge, which consists of a rotating drum or bowl. The centrifuge spins the oil at high speeds, generating centrifugal force. This force causes the heavier impurities, such as solid particles, water, and sludge, to move towards the outer edges of the rotating drum.
  • Collection and Discharge: As the waste oil spins within the oil centrifuge machine, the separated impurities accumulate on the inner walls of the drum, forming a layer commonly referred to as the sludge or cake. The clean oil, which is lighter, remains in the center and is directed out of the centrifuge for further use or recycling.
  • Sludge Removal: The accumulated sludge needs to be periodically removed from the centrifuge to maintain its efficiency. This can be done manually or automatically, depending on the design of the centrifuge system. The collected sludge is typically stored for proper disposal or further treatment, adhering to environmental regulations.
  • Monitoring and Control: The waste oil filter system includes monitoring and control features to ensure optimal performance. This can involve measuring parameters such as oil flow rate, pressure, temperature, and monitoring the separation efficiency. It helps to ensure that the system is operating within desired parameters and enables timely adjustments or maintenance if required.
