Embodiment Construction

[0012] The present invention will be further described below in conjunction with the drawings and embodiments.

[0013] figure 1 As shown, a marine explosion-proof mixed flow fan includes an outer cylinder body 1, an inner cylinder body 2, an axial flow motor 3, a centrifugal impeller 5, an air inlet 6, a rear guide vane 7 and an air outlet 8. The centrifugal impeller 5 is installed on the motor shaft 4 of the axial flow motor 3. The axial flow motor 3 is installed in the inner cylinder 2. The inner cylinder 2 is connected to the outer cylinder 1 via the rear guide vane 7, and the rear guide vane 7 is a twisted blade type. The air inlet 6 and the centrifugal impeller 5 are matched and installed at one end of the outer cylinder 1. The air inlet 6 is an arc cylinder with openings at both ends larger than the diameter of the middle part. The outer cylinder at the outlet of the centrifugal impeller 5 is Open outwards, the centrifugal impeller 5 is a cast aluminum alloy cast airfoil....

Abstract

The invention relates to a blast protection mixed flow blower for a ship. The blower comprises an air inlet, an axial flow motor, a centrifugal impeller, an inner barrel, an outer barrel, a back-positioned guide vane and an air outlet, wherein the centrifugal impeller is mounted to a motor shaft of the axial flow motor; the axial flow motor is mounted into the inner barrel; the inner barrel and the outer barrel are coupled via the back-positioned guide vane; the air inlet and the centrifugal impeller are cooperatively mounted to one end of the outer barrel; and the air outlet is mounted to the other end of the outer barrel. Through combining the air supply structures of traditional axial flow blower and centrifugal blower, the blast protection mixed flow blower for the ship meets the air quantity and air pressure requirements of the centrifugal blower, and possesses the advantage of installation flexibility of the axial flow blower, and is suitable to be used in ship equipment with high requirement.

Description

Technical field [0001] The invention relates to a fan, in particular to an explosion-proof mixed flow fan for ships. Background technique [0002] Marine fans are generally divided into centrifugal fans and axial fans. Centrifugal fans are characterized by small air volume and high pressure; axial fans are characterized by high air volume and low pressure; however, with the rapid development of the shipbuilding industry, marine equipment is increasing. The more advanced, the higher the requirements for the performance of the fan. [0003] Centrifugal fans usually require a large space and special pipelines for layout. Because of the limitations of the ship’s environment and places, there is generally not enough space for layout. Axial fans can be arranged using ship ventilator tubes, but the pressure is not high. Generally speaking, the static pressure of the axial flow fan is generally not more than 600Pa. When the system requires a higher static pressure, the purpose is only ach...
