The principle of Marine blower

The working principle of Marine blower is mainly based on the principle of gas dynamics, through the conversion of mechanical energy into gas pressure energy and kinetic energy, to achieve gas transmission and circulation. The following is an overview of the working principle of several common Marine blowers:

First, the principle of centrifugal blower

The working principle of centrifugal blowers is similar to that of centrifugal pumps. The motor drives the impeller to rotate at a high speed, and the gas enters the impeller from the axial direction, is accelerated by the impeller and flows to the fan outlet along the involute line in the involute shell. In the impeller, the gas is affected by centrifugal force, and is thrown from the center of the impeller to the outer edge, the gas velocity increases, and the dynamic pressure head increases. After the gas enters the volute, a part of the dynamic pressure head is transformed into a static pressure head, so as to realize the compression and transportation of gas. Centrifugal blower is suitable for large flow, low and medium pressure air applications.

Second, the principle of axial flow blower

The working principle of axial flow blower is based on the blade profile theory. The gas flows into the impeller from the axis, and under the action of the impeller blade, the gas obtains energy and flows out along the axis. The blade has a pushing effect on the gas, so that the gas moves along the axis of the fan, forming an axial flow. Axial blower usually has a higher pressure coefficient and a lower flow coefficient, which is suitable for occasions where large air volume and low wind pressure are required.

Third, Roots blower principle

Roots blower is a fixed displacement rotary fan, relying on two meshing rotors in the cylinder for relative motion to compress and transport gas. When the rotor rotates, the working volume formed between the rotor and the cylinder wall constantly changes, thus completing the process of gas inhalation, compression and discharge. Roots blower has the characteristics of simple structure, smooth operation and suitable for various uses.

Fourth, the working characteristics of Marine blower

Marine blowers usually need to consider the special environment and use requirements of the ship in the design, such as corrosion resistance, vibration resistance, miniaturization and so on. In addition, Marine blowers also need to have the characteristics of high efficiency and energy saving to reduce the energy consumption and operating costs of the ship.

In summary, the working principle of the Marine blower is mainly based on the principle of gas dynamics, and the transmission and circulation of the gas is achieved through the conversion of mechanical energy into gas pressure energy and kinetic energy. Different types of Marine blowers differ in their working principle, but they are all designed to meet the specific gas handling needs of the ship.
