Dacheng C series multistage centrifugal blower won the highest award of energy saving products for small and medium sized enterprises in Japan in 2020

C series multistage centrifugal blower is a new generation of high-efficiency and energy-saving blower developed by Shandong Dacheng Machinery Technology Co., Ltd. On January 29, 2021, it won the "director of small and medium enterprises Award", the highest award of energy saving products for small and medium enterprises in 2020, issued by the Japanese Ministry of economy and industry (equivalent to China's Ministry of Commerce).

01

High efficiency and energy saving design

Compared with ordinary roots blower, C series multistage centrifugal blower can save energy by 15% ～ 20%. In order to reduce internal leakage, K series blowers adopt high-precision impeller and reduce the clearance between casing and impeller to ensure the best volumetric efficiency, and adopt high-speed broadband motor direct drive, so as to achieve the highest energy saving and noise reduction.

02

Low noise and low vibration design

The noise index of c-series multistage centrifugal blower is 10 ~ 15dB (a) lower than that of ordinary Roots blower. Moreover, the c-series multi-stage centrifugal blower is more high-frequency noise, which is easier to be isolated and controlled. C series multi-stage centrifugal blower is not only a new type of cast aluminum alloy impeller, but also a delicate design of mechanical properties: (1) the new design of the casing structure can reduce the aerodynamic noise and vibration of the exhaust port（ 2) The new suction muffler can reduce the aerodynamic noise（ 3) At the same time, the special shaft seal structure of the blower further reduces the noise and vibration of the blower.

03

Compact design

Compared with the existing products, under the premise of the same caliber, the C series multi-stage centrifugal blower adopts special impeller and high speed design, realizing the coverage of more than 120% of the maximum flow. At the same time, a specially designed suction muffler is used to reduce the size of the whole package. The installation of the blower does not need to be fixed by the anchor bolts, which saves the installation time. Maintenance free grease lubricated bearing, without oil seal, maintenance is more simple and convenient.

This series of blowers are mainly used in water treatment, pneumatic conveying, vacuum packaging, aquaculture, shipbuilding and other industries.

In Shandong Vocational College of tourism industrial operation for 2 years. Good operation and stable performance.

It has been continuously running for one year in Shandong Dacheng Inspection line. Good operation and stable performance.
