Centrifugal fans are not unfamiliar to many people. It is a kind of machinery manufactured through special equipment, and its working principle is to discharge the internal pressure into the external environment. Judging from the current market applications, centrifugal fans are mainly used in places such as factories and tunnels. During operation, the centrifugal fan mainly relies on the rotation of the impeller to discharge the corresponding gas and change the flow direction of the gas.

However, in the actual use process, centrifugal fans are often affected by the surrounding environment and many other factors, resulting in their working efficiency being less than satisfactory and difficult to meet the actual needs well. So, how exactly can we improve the working efficiency of centrifugal fans?

First of all, before the equipment is put into trial operation, it is necessary to carefully check whether the relevant wiring strictly complies with the regulations and standards, and at the same time, measure the input current during the operation of the equipment. It is necessary to ensure that the input current is within the safe range allowed by the equipment to avoid damage to the equipment due to abnormal current.

Secondly, whether it is a full voltage start or a step-down start, it is necessary to reasonably control the magnitude of the current generated during the starting process. If the capacity of the power grid is limited and cannot meet the current demand under the current starting method, then it is necessary to consider using other appropriate starting methods for operation to ensure that the equipment can be started smoothly without affecting the normal operation of the power grid.

Thirdly, if a dual-speed fan is used, the fan should be started at a low speed first before the trial operation, and carefully check whether the rotation direction of the fan is correct. This is because if the rotation direction is wrong and a high-speed start is carried out directly, it may have an adverse impact on the performance of the fan and even cause damage between the equipment components.

The above are several common methods to improve the efficiency of centrifugal fans. In addition, the key lies in regularly maintaining the centrifugal fan during daily use, promptly discovering and dealing with the problems existing in the equipment, reducing the wear between the equipment components, so as to avoid a negative impact on its performance due to excessive equipment wear and ensure that the centrifugal fan can operate continuously and efficiently.
