      Tianjin Blower Group Co., Ltd. is a professional manufacturer of various fan designs and manufacturers. The company has engineering and technical personnel, advanced processing equipment, production technology and perfect detection methods and management systems, strong technical force and stable product quality.

      High pressure Roots blower is a commonly used air blower. Our high pressure blower is widely used in steel smelting, thermal power generation, new dry cement, petrochemical industry, sewage treatment, waste heat recovery, gas recovery and other fields. Two non-contacting rotors move in the cylinder at the same speed in the opposite direction, pushing the air flow from one side to the other. When the high-speed airflow moved to the vicinity of the exhaust port and communicated with the exhaust port, the gas in the working volume suddenly increased due to the return of the gas with a higher pressure, and the gas was sent out. The high-pressure roots blower keeps the two rotors meshing by the synchronous gear at the end of the rotor shaft. Each concave curved surface part of the rotor and the inner wall of the cylinder constitute a working volume, and the gas is taken away from the suction port during the rotation of the rotor, and the two rotors work alternately in turn. By increasing the power, strengthening the rotor group, increasing the volume, increasing the speed, and adjusting the impeller clearance, the air inside the air cavity is compressed and the pressure is increased.

      High pressure roots blower installation and maintenance:

      1. The installation site must be installed indoors where it will not be affected by wind and rain.

      2. The ambient temperature should usually be below 40 ° C.

      3. Relative humidity, below 80%.

      4. If the transport medium contains corrosive gases such as acids and alkalis, special design is required to avoid danger.

      5, dust protection, there is a lot of dust, powder three-dimensional or fiber and other places should be equipped with filters, and regularly clean the dust attached to the filter and the fan.

      6. Ventilation and heat dissipation, choose to use in well-ventilated places, not in closed rooms or closed boxes with small spaces.

      7. The storage space is convenient for routine maintenance and repair, and avoids installation in too small a place.

      8. Avoid vibration and install it in a place without vibration; if the vibration of the place is unavoidable, take measures to reduce vibration.

      Harm of Boiler Blower Noise and Its Prevention

      1. Harm of environmental noise pollution

      The impact and harm of noise on the human body can generally be divided into two aspects: labor protection and environmental protection. The former refers to endangering human health and causing various diseases. The latter refers to disturbing the quiet environment and affecting people's normal work and life. The harm of noise to human health is mainly manifested in: damage to hearing, causing noise-induced deafness; leading to cerebral cortex excitement and balance imbalance, cerebrovascular function damage; damage to the system, causing digestive disorders; interference to people's normal life, rest, language conversation and daily life Work learning, distracting and reducing work efficiency.

      2. Basic principles of noise management

      There are three main factors that contribute to noise pollution: sound sources, media, and receivers. Only when these three exist at the same time can the listener be disturbed. Starting from these three aspects, the purpose of controlling noise can be achieved by reducing the sound source, limiting the transmission of noise, and blocking the reception of noise. In specific noise control technologies, three types of sound absorption, sound insulation, and noise reduction can be used. Measures.

      2.1 sound absorption

      When sound waves are incident on the surface of an object, part of the sound energy is absorbed by the object and converted into other forms of energy, which is called sound absorption. The sound absorption performance of a material is expressed by the absorption coefficient. The larger the sound absorption coefficient, the better the sound absorption performance of the material. The sound absorption performance of a material is related to the material's properties, structure, angle of incidence of sound waves, and frequency of sound waves. The sound absorption mechanism of porous sound absorbing materials is: there are numerous small holes in the material that penetrate through each other. When sound waves are incident on the surface of these materials and then into these small pores, the air movement in the pores is caused to abut The air on the wall of the hole and the surface of the fiber is difficult to move due to friction and viscous motion resistance, so that the sound energy is converted into heat energy and consumed. Therefore, sound-absorbing materials with good performance must be porous, and the holes must be connected with each other, and the through holes must communicate with the outside world so that sound waves can enter the material.

      For example, the sound absorption coefficient of a 10cm-thick ultra-fine glass wool is 0.87 for a 1000 Hz sound wave.

      2.2 Sound insulation

      The method adopted for sound insulation is to close the noise source so that the noise is controlled in a small space. This sound insulation structure is called a sound insulation cover. When the sound wave encounters the shield, due to the change in the characteristic impedance of the interface, part of the incident sound energy is reflected, part is absorbed, and part of the sound energy penetrates the shield and continues to propagate. The sound insulation performance of a material can be expressed by the sound transmission coefficient. The smaller the sound transmission coefficient, the less the sound energy transmitted through, and the better the sound insulation performance of the material. The sound insulation performance of a material is related to the structure and properties of the sound insulation body and the frequency of the incident sound wave.

      2.3 Silence

      Sound reduction is to fix the porous sound-absorbing material on the inner wall of the airflow channel or in a certain way to achieve the purpose of reducing aerodynamic noise. The amount of noise reduction can generally reach 10-50 decibels.

      3. Fan noise management technology

      The noise of the blower and induced draft fan in the boiler room is generally around 90 decibels. Because the temperature of the boiler flue gas being conveyed is as high as 180 ° C, the use of closed sound insulation can cause poor heat dissipation, excessive motor temperature, and even burn the motor. Therefore, in the process, the fan noise reduction and energy saving are combined. Through practice, the comprehensive control plan for energy saving and noise reduction of boiler fans is as follows: keep the process layout of the boiler room unchanged, place blowers and induced draft fans in sound insulation rooms, connect them to the host with ventilation pipes, and place them on the top of the sound insulation room. An air inlet is installed on the top or wall, and a muffler is installed for air intake in the machine room. In the plan layout, place the blower close to the side of the boiler room, the air inlet is on the upwind side, and the motor is placed in the middle of the air flow channel. When the boiler is running, due to the negative pressure generated by the blower in the sound insulation room, a large amount of outdoor fresh air will automatically enter the sound insulation room. The Tianjin fan first exchanges heat with the induced fan motor to cool it down and maintain the indoor temperature at about 50 ° C. .

      What is the comparison and analysis of the operating principles of roots fans and air suspension fans?

      Roots blower operation principle:

      Roots blowers are positive displacement gas compressors. They are:

      ①Forced flow, within the design pressure range, when the resistance of the pipe network changes, its flow change is small. In the workplace where the flow requirement is stable and the resistance change is large, it can be automatically adjusted and the work adaptability is strong. Low price compared to centrifugal blowers.

      ② It has a lot of noise and has the disadvantage of leaking lubricant to the cylinder. At the same time, the air volume cannot be adjusted. It can only use variable frequency speed regulation and air outlet pipe bleed. Air deflation causes waste of energy and therefore low efficiency, so it is very suitable for use in industrial sewage plants, but due to its high noise and low efficiency, it has been widely eliminated in advanced international sewage treatment processes, and in China Sewage treatment is in the early stages of development. Due to its low value, ease of operation, and traditional habits, many projects are still in use.


      2. Principle of air suspension centrifugal blower:

      ①Bearing material: permanent magnet

      ② The main shaft of the motor rotates at high speed through a high-speed motor. At the same time, an air film is formed between the main shaft and the bearing. The air film generates pressure to cause the bearing to levitate while driving the impeller.

      ③Since it adopts active oil-free air suspension bearing, no lubrication device is needed, and the structure is simple and accurate.

      ④ Tested technology: ECS / ACM for aircraft startup.

      ⑤ 50 years (semi-permanent) 20,000 start-stop tests.
