Extraction phenomenon of marine gearboxes - marine auxiliary gearboxes
Marine gearboxes may experience air extraction during use. How much do you know about this phenomenon? Below, we will introduce the air extraction phenomenon of marine gearboxes:
Ship auxiliary gearbox - used for higher ship gearboxes that cannot be directly vented to the atmosphere. Direct venting to the atmosphere can cause a large pressure difference between the suction and exhaust ports of the ship gearbox, resulting in overload of the ship gearbox. To ensure that a higher vacuum can be reached, it is necessary to ensure a clear space between the rotors of the ship gearbox.
Forward HC Marine Gearbox - It is necessary to have a front-end pump when in use, which is used to suction the pressure inside the system to a certain range before starting the marine gearbox.
Forward HC marine gearbox - This can avoid overloading of the marine gearbox. The front stage pump can be selected from vacuum pumps such as water ring vacuum pump, rotary vane vacuum pump, slide valve vacuum pump, reciprocating vacuum pump, etc., which can directly discharge the atmosphere.
Forward HC Marine Gearbox - Due to the continuous flipping of the rotor of the marine gearbox, the sucked gas is sucked into the space between the rotor and the pump casing through the intake port, and then discharged through the exhaust port. After suction, the space is completely closed
Lightweight high-speed marine gearbox - the gas inside the pump chamber does not contract or expand, but when the top of the rotor rotates past the edge of the exhaust port and the space is connected to the exhaust side.
Forward HC ship gearbox - Due to the high gas pressure on the exhaust side, a portion of the gas rushes back into the space, causing a sudden increase in gas pressure. When the rotor continues to transform, gas is discharged outside the pump.
Forward HC Marine Gearbox - After understanding the suction phenomenon of marine gearboxes, I believe it will be more helpful and bring greater benefits to everyone. That's all for the above knowledge.
