Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that the size and noise of the current ship fan is relatively large, and the land-use model does not meet the conditions for ships, and proposes a low-noise high-speed diagonal flow fan for ships. The fan has a small installation size and The feature of low noise can meet the limited installation space of the ship and the silent requirements of the crew for the cabin

Abstract

The low-noise high-speed oblique flow fan comprises a flow collecting shell, a flow guide cover, an impeller, a diffusion shell and a motor, the flow collecting shell and the diffusion shell are fixedly connected to form a fan diffuser shell, the rear end face of the diffusion shell is fixedly connected with the motor through an end cover connecting plate, the motor is arranged in the fan diffuser shell, and the flow guide cover is fixedly connected with the impeller. An impeller is fixedly connected to an output shaft at the front end of the motor, and a flow guide cover is fixedly connected to the front end face of the impeller. The low-noise high-speed diagonal flow fan for the ship has the advantages of being small in installation size and low in noise, and can meet installation with limited ship space and silence requirements of sailors for cabins.

Description

technical field [0001] The invention relates to a ship air-conditioning system, in particular to a high-speed oblique flow fan in the ship air-conditioning system. Background technique [0002] Diagonal flow fans combine the characteristics of axial flow and centrifugal fans. The wind pressure coefficient is higher than that of axial flow fans, and the flow coefficient is larger than that of centrifugal fans. It is used in occasions where the wind pressure and flow are "not too small". It fills the gap between axial fans and centrifugal fans, and has the characteristics of simple and convenient installation. [0003] At present, land-use oblique flow fans are widely used, mainly composed of impellers, casings, inlet collectors, deflectors, motors and other components. Low-noise oblique flow fans for ships are required to meet the environmental conditions and use requirements of ships. For example, they have the characteristics of high temperature resistance, shock resistanc...
