Abstract

The invention relates to a contra-rotating axial-flow fan with a lateral external-type one-driving-two motor. The contra-rotating axial-flow fan with the lateral external-type one-driving-two motor mainly solves the technical problems that the manufacturing cost of the existing axial-flow fan is high, the operation reliability and safety are lower, the working difficulty in maintenance is great and the like, and improves the operating environment and the stress situation of the motor are improved. The technical scheme is that a front impeller (2) and a rear impeller (7) are fixedly and respectively installed on two output shafts of a transmission case (6) on a base in an inner cylinder of a main machine cylinder (3), flow guide blades (5) and a flow guide blade adjusting mechanism (4) are arranged in an annular passage between the two impellers, a motor support (16) is arranged outside the lateral direction of the main machine cylinder (3) and a motor (15) which is installed on the motor support (16) is connected with the transmission case (6). The contra-rotating axial-flow fan with the lateral external-type one-driving-two motor is a ventilation device which can be widely used in industries such as mining, metallurgy, chemical industry and power plants and can be especially used for working places of explosion, high temperature, corrosion and the like.

Description

technical field [0001] The invention relates to a ventilator, in particular to an axial flow ventilator. Background technique [0002] At present, the ventilator is a general-purpose machine widely used in various industries of the national economy. There are two types of centrifugal fans and axial fans. The so-called axial flow fan refers to the fan in which the airflow flows along the axial direction in the flow channel of the rotating blade on the axial section. The circumferential direction is evenly arranged on the hub, and the hub is fixedly installed on the motor shaft extension arranged along the axial direction, and the motor is arranged axially along the cylinder. Due to the characteristics of large flow, small volume and low pressure head, this fan is mainly used in various ventilation systems that require large flow. In order to increase the pressure, it is often used in the form of multi-stage combination when it is applied to the ventilation system with long...
