Selection, operation and maintenance of centrifugal fans

 

With the application of centrifugal fans more and more widely, people's demand for it has increased significantly. We can find that whether it is in ventilation or gas transmission, it plays an important role, and how to select, operate and maintain has become the knowledge we need to master.

 

The selection

When selecting the type, it is necessary to pay attention to whether the size and structure of the centrifugal fan can meet the installation requirements, so as to avoid a large gap in the size of aperture, hole distance and thickness during installation, resulting in failure to install.

In the selection, we also need to pay attention to the internal structure and material of the equipment, the internal structure and material will affect the overall performance and service life of the equipment. In the test phase, performance and aging tests can be carried out on the equipment. Through the test, the equipment can be connected to the normal operation of the required environmental conditions, and the service life of the equipment can be roughly understood.

 

Operation and maintenance

1, the way of adjustment should be reasonable.

Some users out of cost savings, will choose to import air throttle flow regulation. Since adjusting the damper itself results in some pressure loss, the system resistance value increases even with the damper fully open.

The air door quality is bad, if use may lead to use of damper blade in the process of internal deformation occurs, so as to make the system along with the increase of the resistance, can also lead to import flow field disturbances, fluid into the impeller, will affect the use of the impeller itself, so if you use import damper adjustment, and the throttle opening is low, can choose the inverter to adjust.

2, site installation and construction should reach the standard

 

Under normal circumstances, the equipment needs to meet the requirements of on-site installation. Some installation sites have higher dimensional accuracy requirements, so the equipment should be designed strictly in accordance with the requirements of on-site assembly. If the construction of the site installation fails to meet the design requirements, the actual operation efficiency of the equipment will be affected.

Many users will choose external construction units to install the equipment, and some construction units are not professional centrifugal fan installation teams. If the supervision of users is not in place during the installation process, and the requirements for acceptance are not strict, it may lead to installation errors and affect the later use of equipment.

 

3. Timely maintenance and operation management

Pay attention to air leakage and blockage: During the use of the equipment, there will inevitably be natural loss, leading to air leakage in the pipe network and increasing the useless work of the equipment. Therefore, it is necessary to pay attention to timely repair of air leakage. If there is a large amount of ash in the pipe network, it will lead to blockage of the pipe network, and it is necessary to clean the pipe network in time.

Deformation: generally in the high temperature environment is prone to deformation, if the production material of the equipment is prone to thermal deformation at high temperature, it will lead to the relative displacement of some parts of the equipment, with the size change, after a long time of use, it is prone to serious deformation.

Check piping system and internal parts regularly according to production plan, repair blocked and worn parts in time, and ask professional personnel to do performance evaluation.
