The structural characteristics and working principle
a The overall structure and its working principle, working characteristics
This product has two impellers installed close to each other, which are respectively driven by two explosion-proof motors to rotate them in opposite directions. The airflow enters the I-class impeller from the collector end along the axial direction, and after being accelerated, the direction of the airflow is deflected and then flows into the-class main engine. After being accelerated again by the -class impeller, the direction of the airflow is reversely deflected and then discharged from the diffuser end along the axial direction.
Detailed Photos
Main parts, work, and working principle
As shown in the figure, this product consists of four main parts: the collector, the I-class main engine, the -class main engine, and the diffuser. The collector is composed of a curved collecting inlet and a guide cover. Its main function is to reduce the local resistance loss of the airflow, in order to create a good air inflow condition for the I-class main engine. And the I-class main engine is made of major parts such as the I-class casing, the I-class impeller, the I-class motor, and so on. The I-class casing is the main body of the bearing, and the main function is to ensure the normal operation of the impeller and the motor and at the same time, the function of the muffler. The I-class impeller is the core part of the I-class main engine to produce the airflow, and the I-class motor is the power part to make the I-class impeller rotate. The working principle is that the airflow entering from the collector end flows along the axial direction into the I-class impeller, and after being accelerated, the direction is deflected and then flows into the-class main engine. And the -class main engine is made of the major parts such as the -class casing, the -class impeller, the -class motor, and so on. The main function of the -class casing and the motor is the same as that of the I-class ones. The -class impeller is the core part of the -class main engine to produce the airflow. The working principle is that the airflow from the I-class impeller is deflected into the -class impeller, and after being accelerated, the direction is reversely deflected, and then flows into the diffuser along the axial direction. And the diffuser is composed of the diffusion cylinder and the guide cover. The main function is to reduce the local resistance loss of the outlet of the airflow and improve the effective power capability of the fan. The airflow is discharged from the fan along the axial direction through it, and at the same time, acts as a rear muffler.
