LZ50 centrifugal blower intelligent maintenance and fault emergency plan

The LZ50 has a modular design that reduces maintenance costs by up to 70% compared to conventional fans. Routine maintenance only needs to replace the inlet filter every 3 months, and the system displays key parameters such as operating current and bearing temperature in real time through the touch screen, and automatically records historical data. If there is an alarm with high motor temperature or high vibration value, the user can quickly deal with it by following these steps:

Abnormal temperature: Check whether the ventilation of the computer room meets the standard, if the ambient temperature exceeds 40°C, you need to start forced ventilation or spray cooling;

Vibration exceeded: check pipeline resonance or foundation settlement, if it is confirmed that it is not an external force factor, you need to contact the manufacturer for rotor dynamics testing;

Filter differential pressure alarm: directly replace the filter cotton, no need to stop and disassemble the equipment.

In addition, the equipment has a built-in anti-surge control system, which automatically increases the SV value when the wind pressure exceeds the SURGE line to avoid impeller surge damage.

For example, in the long-term operation of a sewage treatment plant in Anhui Province, it responded to the fluctuation of influent water quality through intelligent adjustment, achieving zero failure operation for three consecutive years, and reducing maintenance man-hours by 800 hours/year compared with traditional multi-stage centrifugal fans.
