Marine centrifugal fan system

Abstract

The invention provides a marine centrifugal fan system, comprising: a centrifugal fan, a motor device, a drainage device, a monitoring device for real-time monitoring of the liquid level in the centrifugal fan, and a monitoring device for controlling the operation of the motor device and the drainage device and The operating state is monitored, and the control device is used to monitor the operating state of the submerged liquid level sensor of the centrifugal fan. Through fully automatic operation, the water in the centrifugal fan can be discharged in a timely and effective manner, which fundamentally solves the backflow of the centrifugal fan and improves the environment in the cabin; the motor shell adopts a double-layer integral sealing structure, which can effectively prevent the motor from being soaked in water and short-circuited. ;A cooling device is installed to effectively ensure the effect of cooling the motor; by setting the temperature rise sensor of the motor and the temperature rise sensor of the motor bearing, it can effectively ensure that the temperature rise of the motor and the temperature rise of the bearing are kept within the set range at all times; The floating raft damping device is installed to achieve the purpose of damping vibration and noise.

Description

Technical field [0001] The present invention relates to the technical field of ship ventilation equipment, and more particularly to a marine centrifugal fan system. Background technique [0002] The centrifugal fan is an important equipment for the air environment control ventilation system. At present, there is no waterproof, and the ordinary centrifugal fan of single-stage vibration damping. like figure 1 As shown, 100 and 700 are all centrifugal fan located in the base. The centrifugal fan (new fan) 100 is a new wind tube 300 drawn into a new wind in the open-air deck 500; centrifugal fan (exhaust fan) 700 is located in the basement room The inner hot humidity is delivered to the exhaust pipe 800 to the air-shaped exhaust width 900 to the air; considering the beauty requirements of the ship, whether it is in the wind, the winding well 500 is also installed on the exhaust width 900 Sleepy air grid 600 of the hull outer panel. This design will often face a large-wind wave or a s...

Problems solved by technology

[0007] In view of the shortcomings of the prior art described above, the purpose of the present invention is to provide a marine centrifugal fan system, which is used to solve the problem of waterproofing of the marine centrifugal fan in the prior art, which is prone to backflow, or needs to be closed. Air intake and exhaust outlets of the machine greatly reduce the problem of personnel comfort
