Description

Technical Field

[0001] The utility model relates to the technical field of fluid engineering, in particular to a fan pressure diffuser device. Background Art

[0002] The fan diffuser plays a vital role in the fan system. Its core function is to efficiently convert the kinetic energy of the gas into pressure energy, thereby significantly increasing the pressure of the gas medium to meet the needs of various production processes. The diffuser is usually located at the impeller outlet of the fan. Through its unique design, it can guide the airflow and reduce its speed while increasing the static pressure of the airflow.

[0003] The demand for fan pressure diffusion mainly comes from the energy conversion and process requirements of gas during transmission. In the fan system, the gas is accelerated by the impeller to generate kinetic energy, but the kinetic energy does not directly meet the needs of the production process. In order to convert the kinetic energy of the gas into more useful pressure energy, a pressure diffuser is required. In addition, as the gas is transmitted in the system, its speed will continue to decrease, while the pressure will increase accordingly, which is beneficial to the gas transportation and the realization of the process. The pressure diffuser realizes the effective conversion of gas energy by reducing the gas speed and increasing the static pressure, thereby meeting the production process's demand for gas pressure.

[0004] However, in actual use of the above equipment, most of the devices are cumbersome to maintain the motor. In view of this, we propose a fan pressure diffuser device. Utility Model Content
