Explanation of lubrication oil cleaning and high-precision filtration for marine diesel engines. High-output motors suitable for centrifuges and oil pumps are under consideration.

In large marine vessels, the deterioration of lubricating oil and contamination by foreign substances can lead to seizure of the cylinder bearings, directly resulting in serious navigation failures. It is essential to prevent the intrusion of fine carbon (soot) generated by combustion, metal wear particles, and moisture, and to maintain the cleanliness of the oil quality as a key aspect of preventive maintenance. Therefore, the introduction of a "marine lubricating oil cleaning unit" that combines continuous coarse separation using a centrifuge and high-precision filters (removing particles down to 1μm) is indispensable. In this cleaning unit, the "oil transfer pump" that continuously circulates and supplies high-viscosity lubricating oil, and the drive shaft of the "centrifuge drum" that generates strong centrifugal force, require high durability and reliability to withstand long hours of continuous operation and load fluctuations in the onboard environment. The "low-voltage, high-output coreless motor (CMH series)" that we handle is a large-capacity motor with a brushless DC design equipped with Hall sensors, making it a viable option as a robust power source for such marine lubricating oil cleaning devices and various fluid pumps.

basic information

■ Technical Key Points of Marine Engine Lubricating Oil Cleaning - Ultra-precise filtration and engine longevity: By removing coarse moisture and heavy sludge through centrifugal separation and capturing fine particles (1μm) with a fine filter, the oil change cycle is dramatically extended. - Reliability for 24-hour continuous operation: Since it is used in the isolated environment of a ship during navigation, a robust drive system that can withstand vibrations and high temperatures and does not cause sudden failures is essential. ■ Features of the CMH Series for Ships and Plant Equipment - High output and high torque: Compatible with low voltage (DC power supply) operation, it provides ample starting torque for transferring marine oils, which have significant viscosity differences due to temperature changes. - Long lifespan and maintenance-free: The brushless design with hall sensor control, which has no wear parts like brushes, ensures high reliability to support long periods of continuous navigation. - We conduct domestic inspections for all units, from prototypes to small lots, before delivery.

Price information

By leveraging our unique global procurement network (world-standard ODM products), we significantly reduce the development and implementation costs of pumps. Even with small-scale production in the tens of units, we offer price advantages equivalent to mass production, minimizing initial investment and inventory risks for companies.
