Assembly type axial flow fan

Abstract

The invention relates to the technical field of tail end equipment, and discloses an assembly type axial flow fan. The assembly type axial flow fan comprises a fan body, a center motor is arranged inthe fan body, a rotating rod is arranged on the outer surface of the outer side of the center motor, and a positioning pipe is arranged on the outer surface of the outer side of the rotating rod and located in the fan body; a fixing pipe is arranged on the outer surface of the outer side of the positioning pipe and located on the outer side of the center motor, multiple sets of fan blades are arranged on the outer surface of the outer side of the fixing pipe and located on the inner side of the fan body, and a positioning shell is arranged on the outer surface of the outer side of the rotatingrod and located on the outer side of the fixing pipe; and fixing rods are arranged on the two sides of the positioning shell and located on the outer surface of the outer side of the fan body, and air pressure rods are arranged at the top and the bottom of the center motor and located on the inner side of the fan body. According to the assembly type axial flow fan, a clamping and fixing mode is adopted, then the fan is fixed through bolts, the fan is convenient to disassemble and replace, and the assembly type axial flow fan is more convenient to produce and install.

Description

technical field [0001] The invention relates to the technical field of terminal equipment, in particular to an assembled axial flow fan. Background technique [0002] Axial flow fans have a wide range of uses, that is, the airflow in the same direction as the axis of the fan blades, such as electric fans and air conditioner external fans are axial flow fans. It is called "axial flow" because the gas flows parallel to the shaft of the fan. Axial flow fans are usually used in occasions with high flow requirements and low pressure requirements. Axial fans hold the position and move the air. The axial flow fan is mainly composed of the fan impeller and the casing. The structure is simple but the data requirements are very high. [0003] There are certain disadvantages in the use of existing axial flow fans. First, the production and processing are more troublesome, and the installation is basically done by manual welding, which has a great impact on the environment. The equip...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an assembled axial flow fan, which has an assembled installation and production method, is convenient for later disassembly and maintenance, and is convenient for production, improves production efficiency, and has the function of noise reduction, greatly reducing It eliminates the noise and friction generated during the operation of the equipment, improves the durability of the equipment, and solves the troublesome traditional production and processing. It is basically installed by manual welding, which has a large impact on the environment, and the equipment is large in size and the production efficiency of workers. It is relatively low, and the connection method is troublesome. It is inconvenient to disassemble and maintain the motor after it is fixedly connected to the equipment. Finally, when the fan needs to be replaced internally, the size is inconvenient to change, the power is not easy to increase, and the internal noise is relatively large during operation.
