Adopts American Gardner- Denver technology. The round speed of blower is 3550 rpm. The faster round speed, the greater centrifugal force, the higher efficiency, the lower power. In the same air capacity and pressure, the energy consumption of the multistage centrifugal blower is 15-25% lower than the roots blower.
2- Non-bolt installation:
Small tremors, the bearing vibration of the blower is ＜4mm/s. Our multistage centrifugal blower is one and only non- bolt installation blower in China.
3- Customized high-speed and high-efficiency frequency conversion motor.:
Motor frequency is 30-70Hz, round speed of motor is 4000 rpm. The bearing of the motor is Sweden SKF Bearing. The principal axis of the motor is ceramic plating to eliminate the magnetism.
4- Monitoring device:
The monitoring device is real-time monitoring the electricity, the voltage, round speed, vibration and temperature. When the temperature or vibration of the blower is over the setting range, the monitoring device will automatically power off to protect the blower.
5- Air cooling:
The bearing and oil box are on the both ends of the blower to isolate the heat of the rotors and there is the fan for cooling. The air cooling can be used in low temperature and reduce the use cost.
6- Long service life:
The blower cover is integrally casting with HT250 high grade cast iron. The impeller is casting with aluminum alloy. The bearing is using Swedish SKF bearing. The service life of multistage centrifugal blower is 10 years.
7- American Shell lubricant:
The multistage centrifugal blower is using American Shell lubricant. The lubricant can reduce the wear of the bearing and the service cost than lubricating grease.
