This high-pressure air is essential for various critical shipboard functions, including starting diesel engines, operating pneumatic tools for maintenance and repair work, and filling high-pressure air bottles for diving operations.
On ships, high-pressure air compressors are typically used for specific applications, such as for providing air to breathing apparatus and air tools used in underwater diving operations. The high-pressure air produced by these compressors is also utilized in on-board firefighting systems, where it is used to operate air-driven foam and water spray systems. The operation and maintenance of high-pressure air compressors are of utmost importance, and regular checks for leaks, proper lubrication, and filter replacements are essential to ensure their reliable and safe functioning. Additionally, these compressors are equipped with safety features such as pressure relief valves and automatic shutdown mechanisms to prevent overpressurization and potential hazards.
Low-Pressure Air Compressors
Low-pressure air compressors on ships are essential for various onboard systems, including pneumatic tools and equipment required for cargo handling and maintenance. These compressors typically operate at pressures below 150 psi and are used for applications that do not require extremely high air pressure.
Low-pressure compressors on ships are commonly piston type or rotary screw type. The piston type compressors are straightforward in design, consisting of one or more cylinders with a piston driven by a crankshaft to compress the air. On the other hand, rotary screw compressors utilize rotating helical screws to compress the air, offering a continuous and steady flow of low-pressure air.
These compressors play a crucial role in providing air for ventilation, control systems, cleaning, and various other low-pressure applications onboard. They are designed to meet the specific air volume and pressure requirements of different machinery and systems on the ship while ensuring efficient and reliable performance.
Proper maintenance and routine checks are necessary to ensure the smooth operation of low-pressure air compressors on ships. This includes regular inspection of filters, coolers, lubrication systems, and monitoring of air quality to prevent any potential system failures that could disrupt the vessel’s operations.
Oil-Injected Air Compressors
Oil-injected air compressors are commonly used on ships for their efficiency and reliability. These compressors undergo an oil injection process where a certain amount of oil is mixed with the compressed air to reduce heat and friction, resulting in smoother operation and prolonged machinery life. The injected oil also acts as a lubricant, minimizing wear and tear on the moving parts, and preventing corrosion within the system.
These compressors are predominantly used for heavy-duty applications such as powering pneumatic tools, providing air supply for control systems, and supporting various onboard operations. Due to their ability to deliver high volumes of compressed air at high pressures, oil-injected air compressors are essential for maintaining optimal performance in critical ship systems.
Professional maintenance is crucial for the smooth functioning of oil-injected air compressors. Regular inspections of oil levels, filters, and other components are necessary to ensure the compressor operates efficiently.
