Marine medium speed tubular piston diesel engine oil
Shanghai Zhuoli lubricants medium-speed cylindrical piston diesel engine oil main performance:
It is prepared by adding high-purity paraffin-based mineral base oil to high-efficiency compound additive. It has good lubricating properties, lubricating oil film has sufficient load-carrying capacity, and reduces cylinder liner wear; excellent thermal oxidation stability, and minimizes the formation of paint film and product. Carbon and sludge; has sufficient total alkalinity, excellent acid neutralization property, prevents corrosion and wear of acidic substances, meets the requirements of medium speed marine engines using different sulfur-containing fuels; excellent clean dispersion performance, effectively controls piston deposition Keep the piston and engine clean; good water resistance, easy to separate from water without emulsification, and ensure stable operation of the equipment. It has good lubricating properties, excellent thermal oxidation stability and clean dispersion performance, excellent acid neutralization performance, excellent rust and corrosion resistance, and good water resistance.
Shanghai Zhuoli lubricants medium speed tubular piston diesel engine oil advantages:
1) Lubricating oil film has sufficient load carrying capacity to reduce wear under boundary lubrication
2) Excellent thermal oxidation stability, minimize the formation of paint film, carbon deposits and sludge
3) According to the sulfur content of the fuel, the oil must have sufficient total alkalinity to neutralize the acid to prevent corrosion and wear.
4) Excellent clean dispersion, medium speed machine as the main engine of the ship, the dynamic rate is large, the lubricating oil is always in the state of circulation, centrifugation and purification during the working process. Therefore, higher requirements are placed on the clean dispersibility of the oil, and the clean dispersibility of the oil cannot be lowered in the centrifugal purification process. In addition, medium-speed oil directly produces higher gas contact with high-temperature pistons, cylinder liners, and inferior fuels during operation. Therefore, the medium-speed machine has a higher tendency to generate high-temperature deposits, which puts higher requirements on the high-temperature clean dispersion of medium-speed oil. It is necessary to have excellent clean dispersibility for the marine medium speed machine, and at the same time, it is required that the oil does not reduce its clean dispersibility during the centrifugal purification process.
5) Water resistance, which is generally required for marine oils, and medium-speed oils require a certain amount of TBN due to the acidic products produced by the combustion of inferior fuels. The addition of the highly alkaline additive is not conducive to the water resistance of the oil, so it is required to have good water resistance.
Shanghai Zhuoli lubricants medium-speed cylindrical piston diesel engine oil main use:
It is suitable for the lubrication of marine medium speed simple piston diesel engines, large ship auxiliary engines and land diesel generator sets.
Shanghai Zhuoli lubricants for medium-speed cylindrical piston diesel engine oil implementation standards:
JT/T375.0-1998. According to 100C kinematic viscosity and total base number, it is divided into two grades of 4030 and 4015. 4030 is suitable for the lubrication of marine medium-speed simple piston diesel engines, large-scale marine auxiliary engines and land diesel generator sets using harsh conditions of fuel with sulfur content below 3.5%; 4015 is suitable for medium-demanding fuels with a sulfur content of 1.5% or less. Lubrication of marine medium-speed cylindrical piston diesel engines, large-scale marine auxiliary engines, and land diesel generator sets.
