Excellent aquaculture equipment exhibitor Zhangqiu blower appeared at the 10th Guangzhou International Fishing Fair

Shandong Zhangqiu Blower Co., Ltd. was founded in 1968, with more than 50 years of fan

 design, production, manufacturing technology and experience. It has established two

 Sino-Japanese joint ventures and set up a branch in the United States, becoming the

 first company in the domestic fan industry to establish a branch abroad at that time. 

The company has formulated the overall development strategy of "elongating the main

 business, innovating on the new, joint venture cooperation, and developing Dazhanggu",

 and put forward the working concept of "Do, do the best". At present, it has become a

 modern mechanical processing scale enterprise integrating Roots blower, centrifugal 

blower, suspension fan, industrial pump, fan, industrial water treatment engineering and 

equipment, pneumatic conveying complete system, electrical equipment, MVR 

evaporation concentration and product technology and complete system design, 

production and sales. The industrial park covers an area of 430,000 square meters, 

which provides a broad development space for enterprises to leap-forward development

 and joint ventures with enterprises from all over the world. The company was 

successfully listed on the Shenzhen Stock Exchange on July 7, 2011, with stock code 

:002598, becoming another new milestone in the development history of the company.

With the deepening of the national industrial policy and supply-side structural reform, 

combined with its own advantages and market opportunities, the company has

 implemented the relevant diversified business strategy, and actively laid out the three 

industrial platforms of intelligent manufacturing, environmental protection water

 treatment, and new material development and application. By continuously increasing 

research and development investment and strengthening the integration of external 

resources, the three industrial platforms have achieved rapid growth.

Product introduction

01, air suspension high efficiency oxygen blower

About: Air suspension high-efficiency oxygenation blower is an energy-efficient, green 

and environmentally friendly product. It can provide a variety of adjustable oxygen 

supply modes according to the depth of the pool, the breeding area, and the types 

of aquatic products. With one key, the aeration evenly diffuses to each water layer, 

rapidly improves the dissolved oxygen in the water, accelerates the material circulation 

of the pond, eliminates harmful substances, promotes the reproduction of plankton

 and the metabolism of fish and shrimp. The growth and development of fish and

 shrimp can be greatly promoted by improving the utilization rate of food and ensuring 

sufficient oxygen content in high-density aquaculture water.

The air suspension high-efficiency aeration blower uses a wide working condition 

high-efficiency three-way flow impeller, which breaks through the key technology of low

 specific speed design and has high efficiency. The integrated special design of the main

 engine makes the noise less than 70dB(A) and the vibration less than 12um. It adopts 

stepless regulation, the fan can be quickly started and stopped, and the service life is

 greater than 20 years.

02, ZA series new efficient three-leaf roots blower

About: ZA series three-leaf roots blower is Shandong Zhangqiu Blower Co., Ltd. in the

 introduction of American company technology based on the application of the 

company's more than 50 years of design and manufacturing experience, self-designed, 

developed applied to aquaculture industry replacement products, the product in the 

structure and performance has been greatly improved and improved, is the highest 

cost-effective products.

Main features:

1, high efficiency, small size, light weight, compact structure, easy to use and 

maintenance, dense flow classification, wide coverage, users can choose the most 

suitable model;

2, the use of air cooling structure, single stage pressure 39.2kPa without cooling water;

3, the impeller adopts advanced structure, three-leaf shape, high area utilization 

coefficient;

4, the use of precision hard tooth surface straight synchronous gear, keyless connection, 

reliable positioning, smooth operation, low noise, high strength, long life;

5. The sound insulation cover can be assembled according to user requirements, 

so that the noise of the fan can be reduced to 85dB(A) or less.

03, SSR-K series of new energy-saving Roots blower

Introduction: This product is a new generation of high efficiency and energy saving 

Roots blower jointly developed by Dahuang Machinery Industry Co., LTD and Shandong 

Zhanghuang Machinery Industry Co., LTD. On January 29, 2021, Japan's Ministry of

 Economy, Trade and Industry (equivalent to China's Ministry of Commerce) awarded 

Japan's Dawa Machinery Industry Co., LTD., the highest award for energy-saving

 products for small and medium enterprises in 2020, the "Director of Small and Medium 

Enterprise Agency Award." Taking a SSR100K (TBS100) DN100A diameter fan as an 

example, compared with the usual products, it can save 188,000 yen (equivalent to 

11,500 yuan) in electricity bills a year, and reduce carbon emissions by 5.4 tons, making

 outstanding contributions to social conservation of resources and reducing global 

carbon emissions.

The fan has the following advantages:

1, energy-saving design: volume efficiency increased by 5% ~ 12%; Energy saving 

10% ~ 30%.

2, compact design: the same caliber under the premise of more than 120% maximum

 flow coverage.

3, low noise and low vibration design: the use of special shaft design to reduce noise

 3 ~ 5dB (A).

4, maintenance convenience design: drive end bearing with lubrication, exempt from

 daily inspection and maintenance.

04, ZH series three-leaf Roots blower

Introduction: In order to meet the market competition demand, specially launched 

the "Zhanghuang" brand three-leaf roots blower, the performance test verified that 

the product performance fully meet the market soup demand. Its flow rate is 

1.0~58m3/min, and its pressure is 9.8~58.8KPa. The fan also has the significant

 characteristics of "SSR fan" : small size, light weight, large flow, simple structure, 

stable and reliable operation. The fan is mainly used in water treatment, pneumatic

 conveying, vacuum packaging aquaculture and other industries.
