The function of the diagonal flow fan
1. Application site: As the indoor ventilation of general factories and buildings, it can be used as both input gas and Exhaust gas.
2. Type of conveying gas: air and other non-flammable gases, harmless to human body and non-corrosive to steel.
3. Impurities in the gas: no viscous substances are allowed in the gas, and the dust and hard particles contained in it are not more than 150mg/m3.
4. According to the special needs of users, it can also be designed with a magnetic motor drive to achieve infinitely variable speed and variable air volume structure.
5. Gas temperature: not more than 80℃.
What is the difference between diagonal flow fans and axial flow fans
Axial flow fans and mixed flow fans are very similar in appearance, and ordinary people cannot Use the naked eye to tell the difference between the two. Axial flow is the flow of gas parallel to the axis of the fan, such as an electric fan. The enclosure has an open access, with a right-angle curved shape, and the motor can be placed outside the duct. The drain shell expands slowly to slow the flow of air or gas and convert kinetic energy into useful static pressure.
When the impeller of the axial flow fan rotates, the gas enters the impeller axially from the air inlet, and is pushed by the blades on the impeller to increase the energy of the gas, and then flows into the guide vane. The guide vanes turn the deflected airflow into an axial flow, and at the same time guide the gas into the diffuser, further convert the kinetic energy of the gas into pressure energy, and finally introduce it into the working pipeline. Axial flow fans are usually used in applications with high flow requirements and low pressure requirements.
The impeller of the mixed-flow fan makes the air perform both centrifugal and axial motion. The movement of the air in the shell mixes the two motion forms of axial flow and centrifugal, so it is called “mixed flow”.
Mixed flow fan is a fan between axial flow fan and centrifugal fan, which combines the respective characteristics of axial flow fan and centrifugal fan, and is similar to traditional axial flow fan.
How to install the diagonal flow fan
1. When installing the fan, a comprehensive inspection of all parts should be carried out to check whether the parts are complete and whether the connection of each part is tight.
2. When installing the fan, pay attention to keeping the horizontal position of the fan, and adjust the joint surface of the fan and the foundation and the connection of the air outlet pipe to make it natural, and no forced connection is allowed. Pipe weights are added to the components of the fan, and the interior of the fan should be inspected for leftover tools and other objects.
3. After the fan is installed, the impeller must be moved to check whether the impeller rubs the casing. If it is found to be wrong, it must be adjusted. The fan should be used in the open air with rain-proof measures.
4. The fan test operation should be carried out after the overall inspection is passed. In order to prevent the motor from being overloaded, the flow control valve should be closed before the fan is started, so that there is no load when starting, and then the valve will be gradually opened to make it full. Load or design operating point operation.
5. If abnormal phenomena such as violent vibration and impact are found during the operation of the fan, it must be stopped immediately for inspection.
6. If it is found that the motor is overloaded due to the deviation of the operating point, the flow regulating valve can be closed to prevent the motor from being overloaded so that the motor is within the rated current.
7. Regularly remove impurities such as dust and dirt inside the fan, and prevent rust.
