As one of the important supporting facilities of production enterprises, industrial centrifugal fans are also more widely used in the market. They have contributed a lot in ventilation, cooling, dust removal and other operations. Many operators are more concerned about how to choose industrial centrifugal fans and what are the precautions for installation
1) Relevant factors to consider when choosing an industrial centrifugal fan
1. Flow and pressure
The main parameters of industrial centrifugal fans include flow and pressure: the higher the pressure, the smaller the flow, which can also be seen from the fan curve. Therefore, it is necessary to choose the equipment that is more suitable for you within the range of the curve according to the requirements of the company’s own production process conditions.
2. Operating temperature and altitude
The working temperature and altitude will affect the density of the gas, and the altitude will also be related to the air pressure. These two factors have an impact on the pressure of the fan. It is necessary to select the correct fan model according to your own parameter requirements.
3. Air composition
The air composition also plays a crucial role in the selection of industrial centrifugal fans. The content of dust and water vapor in the air and whether it is a corrosive gas are all factors that need to be taken into consideration to select equipment that is more suitable for the usage scenario.
4. Space layout and external dimensions
Generally, the types of outdoor fan projects are divided into new projects or renovation projects. For the renovation project, there will be specific requirements for the basic size, and the space layout needs to be considered, and the fan selection should be made according to the site layout structure and size requirements.
2) Precautions for the installation of industrial centrifugal fans
1. Precautions before installation
Before installation, check whether the specification, model, rotation direction of the impeller, and the motor used for the fan meet the requirements; check the accessories, specifications, quantities, etc. of the accessories according to the packing list; check whether each part of the fan is damaged and deformed due to packaging and transportation, and whether the transmission is Flexible etc.
2. Precautions during installation
When installing, pay attention to check the casing. There should be no tools and sundries in the casing. Apply some grease or mechanical oil to some joint surfaces to prevent rust and reduce the difficulty of disassembly. When connecting the fan and the foundation, the inlet and outlet pipes are connected It should be adjusted to make it fit naturally, not forcibly connected, and it is not allowed to add the weight of the pipe to each part of the fan, and pay attention to ensure the horizontal position of the fan.
3. After the installation is completed, run the test
After the installation is completed and the inspection is qualified, the trial operation can be carried out. In order to prevent the motor from being burned due to overload, the fan start-up and test run must be carried out under no load. The newly installed test run time is not less than 2 hours, if no abnormal phenomenon occurs, it can be used normally.
