In Marine Engine, The Difference And Application Of Low Speed Machine And High Speed Machine?

Low speed engines and high speed engines are two common engine classifications in Marine engines, and there are significant differences in their design and application. As an indispensable power source on board, Marine engine is one of the most important parts.

Low-speed machines usually use diesel engines as a power source, the speed range is 300-600 RPM, usually directly drive the propeller, with a larger steel material to support the weight of the rotor, so the low-speed machine is larger and heavier than the high-speed machine, but the power is greater. The design of the low-speed machine is more mature, more stable and reliable, and the low-speed machine is more energy efficient than the high-speed machine. Due to the higher efficiency and reliability of low-speed machines, they are usually used in situations that require long continuous operation and high power requirements, such as large merchant ships, ocean-going fishing vessels, and ship hoisting.

High-speed machines usually use diesel engines and steam turbines as power sources, and the speed range is 1000-1500 RPM. The design of high speed machines is usually suitable for the power supply of small vessels and auxiliary equipment, such as Marine air conditioning, lighting, cold storage equipment, etc. The advantages of high-speed machine are small size, light weight, fast start, easy maintenance, and can drive the propeller through the gear reduction box to achieve variable speed function.

In general, low-speed machines and high-speed machines have their own unique uses and advantages in the field of Marine engines. The low-speed machine is suitable for occasions requiring high power and reliability, while the high-speed machine is suitable for occasions with higher requirements for volume, weight and starting speed. In practical applications, the appropriate engine type should be selected according to the specific needs and conditions.
