Shandong Dacheng Machinery: The leader of China's multi-stage centrifugal blower products

---Interview with Cheng Guanzheng, Chairman of Shandong Dacheng Machinery Technology Co., Ltd.

The multi-stage (casting) centrifugal blower uses a high-speed rotating impeller to do work on the gas, which increases the gas pressure and speed. The gas with a certain pressure flows out from the edge of the impeller at a higher speed and flows into the diffuser. The gas speed decreases. Part of the kinetic energy is converted into potential energy, so that the pressure of the gas continues to rise, and then the gas flows through the bend and the refluxer into the next stage of compression unit to continue to be compressed; in this way, after compression by the multi-stage impeller, the gas reaching the required pressure will be The shells are collected and fed into the system through the exhaust port. Nowadays, multi-stage centrifugal blowers have the advantages of high efficiency, low noise, stable operation, no pulse, wide stable area, clean, dry and oil-free gas, few wearing parts, easy installation, operation, and maintenance. Replacing the traditional Roots blower has aroused great attention and research enthusiasm in the blower industry at home and abroad.

Shandong Dacheng Machinery Technology Co., Ltd. is the leader of multi-stage centrifugal blowers in China. In 2015, the company developed the first multi-stage centrifugal blower. In 2018, the company successfully developed a permanent magnet high-efficiency multi-stage centrifugal blower, which is widely used in municipal engineering, papermaking, printing and dyeing, metallurgy, food, pharmaceutical, petrochemical, Mines, cement and other industries.

How does Dacheng Machinery achieve breakthroughs in multi-stage centrifugal technology, how does it apply technological innovation and apply it to the blower level, and how does it view the blower market? This issue of China Blower Net interviewed Cheng Guanzheng, chairman of Shandong Dacheng Machinery Technology Co., Ltd.

Close integration of technology accumulation and industrial application

Reporter: Please briefly introduce your company's development history in multi-stage centrifugal blower products?

Cheng Guanzheng: Dacheng Machinery Technology is the first professional company in China to adopt American technology to produce multi-stage centrifugal blowers, and it has made improvements based on actual usage and has two patent certificates. Since its establishment in 2004, the company has been focusing on the research, development, application, promotion and industrialization of blower technology. In 2015, the first multi-stage centrifugal blower was developed, which filled the domestic gap. Since then, the company has continued to develop permanent magnet high-efficiency multi-stage centrifugal blowers and other products based on the technical foundation successfully developed by multi-stage centrifugal blowers.

In 2019, Dacheng Machinery Technology improved the blower control system, and all changed to LCD control screens, which realized the one-button start of multi-stage centrifugal blowers, and the operation was more simple and convenient.

Reporter: How did your company achieve breakthroughs and applications in multi-stage centrifugal blower technology?

Cheng Guanzheng:

Relying on the long-term technical accumulation in blower research, combined with the company's many years of application experience in the industrial field, at the beginning of the development of multi-stage centrifugal blower products, the R&D team combined the characteristics of industrial applications to adapt to various Kind of actual site conditions. The ability to apply this high-tech to industrial products on a large scale is mainly due to the perseverance of our R&D team and the strong support given by many of our outstanding industrial customers, turning various industrial sites into our Run the front line. After repeated tests, field operation and optimization and improvement over and over again, our products have gradually adapted to various industrial field applications. This is a long process, but the experience accumulated bit by bit in this process is a valuable asset, which drives us to serve our customers faster and better.

Product advantages that meet customer needs

Reporter: Can you introduce your product line?

Cheng Guanzheng: At present, the company's products include Roots blowers, multi-stage centrifugal blowers, permanent magnet high-efficiency multi-stage centrifugal blowers, centrifugal blowers, rotary blowers and other products.

Reporter: Compared with traditional products, what are the product advantages of multi-stage centrifugal blowers? What are its customer groups?

Cheng Guanzheng: Compared with traditional Roots blowers, multi-stage centrifugal blowers can save energy by 15%-25%. Energy saving is our main advantage. In addition, the gas is completely pure and oil-free, which can provide customers with cleaner gas. The noise is as low as 75 decibels, and communication next to the equipment is barrier-free, which solves the long-term noise problem of equipment maintenance personnel. In addition, our multi-stage centrifugal blowers have the advantage of convenient daily maintenance and repair.

So far, Dacheng Machinery Technology's multi-stage centrifugal blower series products have been widely used in municipal engineering, sewage treatment, papermaking, printing and dyeing, metallurgy, food, pharmaceuticals, petrochemicals, mining, cement and other industries.

Create a blue ocean of multi-stage centrifugal blower products

Reporter: How does your company develop markets and channel construction?

Cheng Guanzheng: Dacheng Machinery Technology has its own marketing team. At present, the blower mainly combines direct sales and channels. We will cooperate with channel vendors who are interested in energy saving. Currently, we are looking for channel vendors who are interested in cooperation. Interested partners are welcome to contact us and jointly create a blue ocean of multi-stage centrifugal blower products.

Reporter: At present, many blower companies are also developing products such as multi-stage centrifugal blowers. How do you view this phenomenon?

Cheng Guanzheng: Shandong Dacheng Machinery Technology Co., Ltd. is the first domestic enterprise to research multi-stage centrifugal blower technology. It has more than ten years of blower technology research and development and application precipitation, which is the leader of Dacheng Machinery technology experience.

Dacheng Machinery Technology pays special attention to research and development, and has 2 patents, which is the leader of Dacheng Machinery Technology Research and Development.

In terms of the market, Dacheng Machinery Technology has hundreds of multi-stage centrifugal blowers used in high-efficiency and energy-saving applications across the country and overseas countries and regions, and their energy-saving efficiency has been recognized by more and more customers. Praised by many customers and experts, this is the leader of Dacheng machinery technology market.

At present, many blower companies are developing multi-stage centrifugal blower products, indicating the industry’s recognition of this technological trend, and our Dacheng is also a technology-leading company. I believe that in the near future, multi-stage centrifugal blowers will have opportunities in the blower industry and customers. It is widely used in China, and it truly saves a lot of electricity for customers from all walks of life, and makes great contributions to the circular economy and energy conservation and environmental protection.

Reporter: In addition to existing products, will your company go deeper into the blower industry in the future?

Cheng Guanzheng: Yes, we are now cooperating with TNE in South Korea to develop our own air suspension blower. We have been deeply engaged in the field of wind turbines for more than ten years, and wind turbines are a larger part of the company's production electricity bills. It has always been our vision to use our technology to provide users with efficient and energy-saving system solutions. Dacheng Machinery Technology conforms to the national energy saving and emission reduction initiative.
