Why is the output pressure of air suspension fan too low?

The main components and working principle of air suspension blower. The core components of air suspension blower include impeller, air suspension bearing, frequency converter and high speed permanent magnet motor. The impeller generates air flow when rotating at high speed, thus achieving blast. Air suspension bearing is one of the key technologies of air suspension blower. By using gas as lubricant, the sliding bearing can realize non-contact support and effectively reduce mechanical friction and energy loss. The frequency converter is used to adjust the speed of the high speed permanent magnet motor to adapt to different working requirements. High speed permanent magnet motor is the power source to drive the impeller rotation, which has the characteristics of high efficiency, high power density and high speed. Through the cooperative work of the above components, the air suspension blower can achieve high efficiency, low friction, oil-free lubrication and high reliability of the blast effect

On the one hand, there may be a problem in the selection of air suspension blower, if the operating point and the design point deviate greatly, it will lead to low efficiency of fan operation, resulting in insufficient fan output. At the same time, I think of the shortcomings of the equipment in the design, such as the small design parameters, the actual operating parameters are much larger than the design parameters, so that the fan can not meet the load of the unit.

On the other hand, it may be the installation and manufacturing reasons, the reverse installation of the adjustment door and the excessive coordination gap will cause the fan performance to be greatly reduced; The blade profile also has a great influence on the output and efficiency of the fan. There are also cases of damage to the blade profile due to improper manufacturing or running wear.

On the other hand, it is related to operation and system aspects, including incorrect indication of the opening of the adjustment door, unreasonable arrangement of the system pipeline, and so on.
