The working principle of marine spare parts mainly includes the following aspects:
Rubber isolator: Marine machinery and equipment will encounter external interference such as wind and waves and engine vibration when sailing at sea, which will have different degrees of impact on the hull and equipment. Rubber isolator isolates vibration through the deformation characteristics of rubber, converts the vibration energy generated by the operation of mechanical equipment into heat energy, thereby reducing the degree of vibration transmission to the hull.
Ship propeller: The ship propeller converts the power generated by the engine into the thrust of the ship to overcome the resistance of the ship sailing in the water and promote the ship's progress. The propeller is a common ship propeller. Its working principle is that when the propeller rotates, the blades continuously push a large amount of water backwards, generating a forward force on the blades, that is, the propulsion force. The propeller blades are like a small section of the wing. The component force of the hydrodynamic force on the blades in the forward direction constitutes a pulling force, that is, the ship's propulsion force.
Marine air conditioning ventilation accessories: Marine air conditioning ventilation accessories use natural ventilation accessories to defeat the friction resistance caused by the fluidity of the gas in the system, so that the transported air volume meets the design requirements. These accessories include centrifugal fans, axial flow fans, etc., which use the twisting action of the motor rotor to pressurize the inhaled gas to the exhaust duct, thereby achieving the functions of ventilation and smoke exhaust.
