China's high-speed railway in Chinese blower industry - Dacheng Machinery

Because of its stability and rapidity, the high-speed railway has been praised by people both at home and abroad. China's high-speed rail has become the first in the world. Someone once put a dollar coin on China's high-speed rail. The coin persisted for eight minutes and did not fall until the train slowed down, showing that the stability of China's high-speed rail was not blown.

If you think the miracle of "a dollar coin stands alone" can only appear on the Chinese high-speed rail, then you are wrong, Shandong Dacheng Machinery Technology Co., Ltd. as a leader in the blower industry, the latest product C Series casting multi-stage Centrifugal blowers can also make the miracle of a dollar coin not fall, but not for eight minutes, it is for ever, indicating that this C Series cast multistage centrifugal blower has a high performance in noise and stability.

Dacheng Machinery C Series casting multistage centrifugal blower What will make a coin stand up? Here I will give you a brief introduction of this machine into the machine.

C Series Casting Multistage Centrifugal Blower is Dacheng Machinery introduced the United States and the development of technology with the advanced world-level high-efficiency centrifugal blower products, the series uses a number of proprietary or patented technology, the fan of low noise, low vibration, high efficiency Etc. than the domestic product has obvious advantages.

1- Energy-efficient:

Adopts American Gardner- Denver technology. The round speed of blower is 3600 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 efficient broadband 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.
