Detailed Description
The vertical damping structure of the axial flow fan of the invention is explained with reference to the accompanying drawings.
As shown in fig. 1, the vertical damping structure of the axial flow fan comprises an axial flow fan 1 vertically arranged in a steel plate surrounding wall, a damper 4, a supporting plate 3, a split base 6, a flexible joint 2 and a connecting bolt 5, wherein four corners of the split base 6 are uniformly distributed and welded on a deck 8, the damper 4 and the fan are connected into a whole by the supporting plate 3 and are located on the split base 6, and the supporting plate 3 is arranged between the damper 4 and the axial flow fan 1; the upper and lower parts of the axial flow fan are respectively provided with an upper flexible joint and a lower flexible joint, the lower flexible joint is arranged below the supporting plate and is connected with the air duct cabin communicating piece, and the upper and lower end surfaces of the flexible joint and the upper end surface of the supporting plate are respectively provided with a sealing gasket 7.
The novel ship damping device is used in a place with a narrow ship space and a limited installation space, can reduce the occupation of effective space, can be used for passenger ships with high requirements on vibration and noise, can solve the problem of limited space, and has good damping and noise reduction effects.
The vertical installation method of the axial flow fan comprises the following steps: the method comprises the following steps that a designer selects a proper fan arrangement position according to an actual spatial position, and then selects four split bases with unused four corners to be spatially arranged; selecting proper shock absorbers, support plates, sealing gaskets and the like according to the information of the size, weight, dynamic load and the like of the fan; the specific installation steps are as follows:
1. firstly, connecting a shock absorber with a base through fasteners such as bolts, nuts, gaskets and the like;
2. connecting the fan, the support plate and the lower flexible joint together by using a fastener, wherein a sealing gasket is required to be sealed between the support plate and the fan and between the flexible joint and the support plate;
3. integrally connecting the fan, the supporting plate and the flexible joint with the four-corner shock absorber;
4. a flexible joint connected with the upper end of the fan;
5. connecting the lower end flexible joint and the cabin penetrating piece together, and paying attention to sealing gaskets;
and after the installation is finished, the vertical shock absorption of the axial flow fan meeting the requirements is finished after the quality inspection acceptance is qualified and the shipowner is qualified.
The vertical shock absorption installation method of the axial flow fan can be popularized in the field of ship air conditioning ventilation, achieves shock absorption and noise reduction of a ship while achieving effective space maximization, and integrally improves the comfort level of the ship.
