Abstract
The invention relates to a novel axial flow fan for a ship. The novel axial flow fan comprises a fan shell, a motor and an impeller. One side of the motor is supported in the fan shell through a support with a radial shock absorber. The motor is supported in the fan shell in a mode that supporting is achieved through the support with the radial shock absorber, so that when the motor works, radial shock absorption of vibration of the motor can be achieved through the radial shock absorber, the shock absorption effect of the motor is improved, and finally it is ensured that the fan works stably, and produces small noise. Shock absorption of the motor from any direction of the circumference of the motor can be achieved through oppositely-arranged supports or evenly-distributed supports, so that the shock absorption effect is improved.
Description
Technical field
The present invention relates to a kind of axial-flow blower, is a kind of New Marine propeller fan specifically.
Background technique
Along with developing rapidly of China's ship industry, increasing modernization high-tech, high-caliber equipment investment will be had in shipping transport.Fire-fighting smoke exhaust system on ship is for guaranteeing when starting fire-fighting system, the a large amount of high-temperature flue gas produced can be discharged to out of my cabin effectively in time, improve compartment environment, usually adopt propeller fan smoke evacuation, traditional Axial-flow fan motor vibrations are realized by the shock-absorbing support of blower fan, but its stabilized equipment support blower fan overall weight, damping burden is large, takies the outside installing space of blower fan, cost of production is high, and damping effect is when bearing larger, effect is low, and working life is short.
Summary of the invention
For the above-mentioned deficiency of prior art, the invention provides a kind of structure simple, compact, reduce production, user cost, reduce assembling volume, improve the New Marine propeller fan of damping effect and physical life.
The technical solution used in the present invention is: a kind of New Marine propeller fan, comprises Fan casing, motor and impeller, it is characterized in that: the seat supports of the side band radial shock absorber of described motor is in Fan casing.
A kind of New Marine propeller fan, comprises Fan casing, motor and impeller, it is characterized in that: the seat supports of the both sides difference band radial shock absorber of described motor is in Fan casing.
A kind of New Marine propeller fan, comprises Fan casing, motor and impeller, it is characterized in that: the periphery of described motor through the seat supports of multiple uniform band radial shock absorber in Fan casing.
Adopt technique scheme, the invention has the beneficial effects as follows: the support of motor in Fan casing, realize by being with the bearing of radial shock absorber, when machine operation, the vibrations of motor realize radial damping by radial shock absorber, improve motor shock absorption effect, finally guarantee the stable working of blower fan, low noise.Motor, by relative bearing or uniform bearing, realizes motor any direction damping circumferentially, improves damping effect.
Accompanying drawing explanation
Fig. 1 is one embodiment of the invention structural representation.
In figure: Fan casing 1, motor 2, impeller 3, bearing 4, radial shock absorber 5.
Embodiment
Be described further below in conjunction with drawings and Examples.
Shown in Fig. 1: a kind of New Marine propeller fan comprises Fan casing 1, motor 2, impeller 3, bearing 4 and radial shock absorber 5.The bearing 4 of the side band radial shock absorber 5 of motor 2 is supported in Fan casing 1, and motor 2 is in transmission connection the impeller 3 be arranged in Fan casing 1.
Above-described embodiment is the enforcement of a kind of technological scheme of the present invention, and every employing motor is supported on the technology in Blower Housing by radial shock absorber, and simple modifications on this basis, all in scope.
Claims (3)
