Jiangsu Roots Fan-Roots Fan Wholesale-Jin Blower Group Co., Ltd .:Tianjin fan , Tianjin blower , Tianjin fan
Tianjin Blower Group Co., Ltd. is a professional manufacturer of various fan designs and manufacturers.
Centrifugal force type balancing machines can be divided into soft supporting balancing machines and hard supporting balancing machines according to different supporting characteristics. The balance speed is higher than the natural frequency of the rotor-supporting system. This kind of balancing machine has a small support stiffness, and the signal detected by the sensor is proportional to the vibration displacement of the support. The balance speed lower than the natural frequency of the rotor-supporting system is called a hard-supported balancer. The support rigidity of this balancer is large. The signal detected by the sensor is proportional to the vibration force of the support.
Centrifugal fan impellers can be divided into two types: backward inclined centrifugal impellers and forward inclined centrifugal impellers according to the impeller blade installation direction. According to the impeller structure, the impeller can be divided into two types: multi-wing impeller and sub-wheel. According to motor installation requirements, it can be divided into outer rotor impeller and inner rotor impeller.
Centrifugal fans are auxiliary production equipment commonly used in stone processing enterprises. They are mainly used in ventilation and dust removal devices. For example, cyclones and bag dusters in the stone cutting and grinding processes need to use centrifugal fans to remove dust from the production site. Ensure that the production environment is clean and protect the physical and mental health of producers.
Roots blower maintenance process and quality standards
1 Preparation before disassembly
(1) Master the operation of the fan, and prepare necessary drawings and documents.
(2) Have all maintenance tools, measuring tools, hoisting tools, accessories and materials available.
(3) Cut off the power supply, and the process is in compliance with the conditions of safety maintenance.
2 Disassembly and inspection
(1) Remove all accessories from the fan, and check the gaps between the rotors and between the rotors and the side walls.
(2) Remove the coupling or pulley, check the elastic ring or V-belt.
(3) Remove the gear box, check the tooth surface and adjust the gear bolts.
(4) Remove the bearing and bearing box, and check the oil seal and bearing.
(5) Remove the sealing parts, and check the sealing parts such as the labyrinth sleeve, moving ring, static ring, and O-ring.
(6) Remove the wall plate and check the wall plate and rotor.

Challenges in the development of roots fans
The chemical, cement, and steel industries are three important application industries for Roots blowers, and their sales have always ranked among the top five in the industry.
The Roots fan industry has been stable since its development, but with the continuous promotion of the market and the continuous expansion of emerging industries, the industry is constantly facing various challenges.
The large amount of fixed asset investment resulting from the elimination of backward production capacity and new production capacity in the cement industry has brought huge market opportunities for the Roots blower industry. According to statistics from the China Cement Association, in 2011, 176 new dry-process cement production lines were newly built and put into production nationwide, with an annual added design capacity of 195 million tons of cement clinker. Among them, there are 69 production lines with a daily output of 5,000 tons and above, accounting for 56.47% of the total added capacity. From 2010 to the Twelfth Five-Year Plan period, with the gradual start of unstarted projects and the gradual implementation of backward production capacity reconstruction projects, fixed asset investment in the cement industry will still maintain a rapid growth rate.
Emerging markets are developing rapidly, and Roots blower manufacturers have great potential for processing water, pneumatic conveyance, and other potential applications.
The water treatment industry has developed rapidly in recent years. The sales of Jiangsu Roots Blower and Roots Blower in this industry have increased rapidly. Take Shandong Zhangqiu Blower Co., Ltd., the industry leader of Roots blowers, as an example. In 2009, 2010, and 2011, the sales of Roots blowers in the water treatment industry accounted for 13.23%, 16.63%, 15.35%. In addition, the rapid growth of emerging industries such as pneumatic conveying and gas separation also makes the Roots blower industry a good development prospect. As a general-purpose air source equipment, Roots blowers are quoted. Roots blowers have many potential application areas. Once the potential market is mature, the market capacity will grow rapidly.
Roots blower has a constant torque load, and its power saving rate is directly proportional to the speed reduction, that is, N% = △ N%. Although it is different from ordinary fans and water pumps, it has a higher power saving rate, but because of its higher power, The wall is not bad, it works continuously for 24 hours, and it starts for a long time. Therefore, the power saving potential is large, and the cost of power saving is high.
