In industrial water treatment, in order to speed up the aeration, the blower is usually used as an auxiliary facility. A powerful and low noise blower is undoubtedly the best choice. The Roots blower is a positive displacement fan. The volume of air delivered is proportional to the number of revolutions. The three-bladed impeller suctions and exhausts three times per revolution by two impellers. Compared with the two-bladed type, the pulsation decreases and the load changes Small, high mechanical strength, low noise, vibration is small, but the simple structure, smooth operation, has been widely used in many areas including water treatment. This issue editor takes you to review the history of the blower to understand several good performance blower products for water treatment. First, the history of Roots blower Since 1849, the British George Jones first developed into a twin-rotor fan, the United States in 1854 Philanders (Philadelphia) Rands (Philander Roots) brothers in the process of designing the water wheel also conceived this fan, and in It was produced in its own woolen mills and exhibited at the Paris fair in 1867 (since it was known as a Roots Blower). For more than 150 years, Roots blowers have made considerable progress. In the same year, it started to be applied industrially (first in smelting). 1951 China began manufacturing Roots blower. 60-70 years, our country developed D series air-cooled Roots blower and SD water-cooled Roots blower, the domestic Roots blower began to form a formal series. Early 80s, long drums and other units jointly designed L series Roots blower. Since the 1990s, Roots blower technology development activities have become more active. Third, Roots blower boutique courier understand Roots blower development and principles, let's take a look at the editors recommend several of your selected products. As one of the largest e-commerce sites in China, HC Network Market has a wealth of products for your selection, here, you want the product. 1, compact low-noise type Some blower start will have a lot of noise, the formation of noise pollution. Following this from Taixing Hengsheng pump equipment factory, the biggest feature is the mute performance is good. ã€Product Parameter】 Model: HC-251S Qs: 0.310-0.280m3 / mim N: 0.1-0.6Kgf / cm2 L * W * H 710 * 255 * 445 (mm) Blower pressure range: 0.1-0.6kgf / cm2 ã€Edit Comments] This Roots Blower compact structure, mainly by the motor, air transition, blower body, air chamber, base (and fuel tank), drip six parts. Blower by eccentric cylinder offset rotor operation, and make the rotor slot in the volume change between the leaves of the air inhalation, compression, spit. In operation, the pressure difference of the blower is used to automatically send lubrication to the dripper and drip into the cylinder to reduce the friction and noise while keeping the gas in the cylinder from flowing back. Although the volume is small, but the air volume, energy saving, quiet operation is unmatched by other forms of fans. And this product warranty period of one year, free warranty repair, life-long service, intend to purchase related products, friends can be considered. 2, Durable Roots blower life has always been one of the most concern when purchasing products, after all, industrial products is different from the daily necessities, in the repair and replacement are very troublesome. ã€Product Parameters】 Flow 0.9m3 / min-900m3 / min Boost 9.8kPa-198kPa specifications of more than 70 ã€Edit Comment】 This unit by the Roots blower one of the world's leading manufacturer of Japan's Akira Machinery Co., Ltd. investment, with Japan's imports Machining center, the product fully adopts Japan's core technology, longer service life, imports Roots blower alternative. The product can be widely used in water treatment, pneumatic conveying, vacuum packaging, aquaculture industry and other industries. 3, energy saving Energy saving is the more important requirement in the process of China's industrial development, to be reflected in the details of industrial production, the so-called small stream, into Jianghai. ã€Product Parameters】 Rated discharge pressure 0.01-0.8mPa Speed ​​850 ~ 1750rpm Rated voltage 380 Imported diameter 40 ~ 300mm ã€Edit Comment】: This product uses computer balancing correction, low vibration and low noise. Stable air volume, pressure changes have little effect on air volume. Special impeller design, can improve high efficiency and save energy. Is the best energy-saving products. When choosing a Roots blower for water treatment applications, the editor recommends that you choose products according to your actual needs based on the parameters provided by the shops. We believe that the energy-saving, durable and low-noise Roots blower will be the mainstream of future market development. Second, the working principle â… â…¡ â…¢ â…£ â… cylinder volume is divided into two parts by the impeller. Among them A communicates with the air inlet, its gas is in the air inlet pressure; B communicates with the air outlet, its gas is in the air outlet pressure. â…¡ cylinder volume is divided into three parts by the impeller. Where A is connected to the air inlet and the gas is at the air inlet pressure; B is connected to the air outlet and the gas is at the discharge pressure; the space formed by the impeller 2 and the housing is connected to the inlet before it reaches this position But also did not communicate with the exhaust port, so the gas pressure in the space is still in the intake port pressure. â…¢ cylinder volume is divided into two parts by the impeller. Where A is connected with the air inlet, the gas is at the air inlet pressure; B is communicated with the air outlet, and the gas is at the exhaust pressure. â…£ At this point and the state â…¡ is basically the same, but the position of the impeller 1 and 2 interchange.

The following is a schematic of the Roots blower.
