How to dismantle Roots fan bearings

Roots fan bearings need to be disassembled in the process of use, so how should the Roots fan be disassembled? I have introduced 5 methods for you. 1, knocking method. Roots fan bearing disassembly in the hammering method is one of the simplest and most common bearing disassembly method. With the force of hammering, the mating parts are displaced and detached from each other to realize disassembly. When using the hammering method to dismantle the bearing, the hammering force should not be applied to the rolling body of the bearing and cage, generally should be applied to the inner ring of the bearing, this dismantling method is simple and easy to carry out, but often damage the parts, and even fail to achieve the purpose of dismantling. 2, pull out method. The use of 2-claw or 3-claw pulling horse and other tools to dismantle the bearing...

Advantages of adopting counter-current cooling for Changsha Roots Blower

Changsha Roots blower adopts counter-current cooling, which has the following advantages: 1 can inhale high temperature gas. When air cooling is adopted and high temperature gas is inhaled, the inhaled gas is generally cooled down to about 40℃ through the front cooler. With countercurrent cooling, the gas temperature can be directly inhaled even at 120℃. 2Can be used at higher pressure ratios. Due to the exhaust gas temperature and other factors, the pressure ratio of single-stage air-cooled blowers is generally not more than 2.0. When countercurrent cooling is used, the exhaust gas temperature decreases, and the permissible pressure ratio is increased. In practice, the pressure ratios of single-stage blowers and vacuum pumps reach about 2.6 and 4.4 respectively. Dry conveyability can be ensured. No injection is used...

Changsha Roots fan common several kinds of gas cooling methods

When the exhaust temperature of Changsha Roots Blower is high, the thermal clearance between the impellers, between the impellers and the casing and wall panels will become very small, and in serious cases, they will be stuck outside each other. In addition, the bearing is very close to the exhaust cavity, and it is more sensitive to the heat transfer of the gas. Therefore, the gas temperature should not be too high, generally does not exceed 120 ~ 140 ℃ Commonly used cooling methods of air cooling, water cooling, countercurrent cooling, etc. Air cooling. The larger the pressure ratio, the higher the gas temperature rise. At ε≤2.0, the exhaust gas temperature is usually not too high. Therefore, the gas only needs to pass through the casing and the atmosphere natural heat exchange can be called air cooling. Water cooling. When the pressure ratio is large, the exhaust temperature will be higher if air cooling is used. At this time can be...

Changsha Roots blower group type

Changsha Roots Roots fan blower group, generally consists of several parts such as the blower, the prime mover and its transmission device. Sometimes also includes some supporting accessories, such as mufflers, filters, safety valves and so on. 1 Single-stage group Usually, small and medium-sized blowers are assembled with supporting motors on the same machine base as a whole for packaging, transportation and installation. In order to make the system more compact and convenient for users to select and install, the blower can also be assembled with the motor, muffler, filter, valve, etc. to form an intensive complete set. Large blowers and motors are large in size. Heavy weight, usually packaged separately, lifted separately, transported to the installation site and then assembled matching, general...

The working principle of the Roots fan

The working process of the Roots fan is that there are two “8” shaped rotors in the cylinder, on both sides of the cylinder. There are inhalation orifices and discharge orifices. Through the role of a pair of synchronized gears, so that the two rotors for the opposite direction of rotation. And rely on the mutual meshing of the two rotors work, so that the inhalation orifice and the discharge orifice are isolated from each other, to push the cylinder volume of gas, to achieve the purpose of the blower. The theoretical compression process of Roots blower is isovolumetric, so its power consumption is greater than other volumetric compressors. When the pressure is relatively high, due to the fixed capacity compression is not economical, as well as through the gap at the joints of the leakage increases, so that the Roots blower loses practical significance. Therefore, the Roots blower ...

What are the factors affecting the accuracy of the main shaft components of Roots fans?

Roots fan spindle component accuracy, refers to the rotational accuracy after assembly and adjustment, which includes the spindle radial circular runout, axial runout and spindle rotation uniformity and smoothness. Factors affecting the rotational accuracy of spindle components are the following aspects. I. Factors affecting the radial runout of spindle components 1, the accuracy of the spindle itself. Such as the different axis of the spindle journal, taper and out of roundness. Spindle journal of different axes will directly cause the radial runout of the spindle, and spindle journal taper and out of roundness in the assembly will cause deformation of the inner raceway of the rolling bearing, destroying its accuracy. 2, the accuracy of the bearing itself. One of the most important is the bearing inner raceway surface out of roundness,...

Roots fan acoustic enclosure basic requirements and air exchange methods

Roots fan acoustic enclosure is the noise in the enclosure, so that it does not escape the noise control device. The basic requirements of the acoustic enclosure is: 1. good acoustic performance, sound insulation amount is relatively large; 2. air exchange device, good heat dissipation performance; 3. observation device, not open the door can be monitored on the blower; 4. there is a proper space, do not dismantle the cover can be refueling, change the belt, and other simple operations; 5. transportation and installation is convenient, the price is appropriate, and so on. Acoustic enclosure has two ways of air exchange. In the self-absorbing air exchange method, the blower air inlet is located inside the hood, and the hood is equipped with an anechoic channel for air intake, and the blower itself is utilized to carry out the need to form a negative pressure inside the hood when it is working, so as to bring the new outside of the hood ...

Types of Roots fan silencers

Resistive muffler is a kind of muffling equipment by controlling the acoustic impedance, this kind of muffler does not use sound-absorbing materials to absorb the sound energy directly, but utilizes the sudden expansion and contraction of the pipe cross-section, so that the noise propagated along the pipeline can be emitted back to the sound source in the sudden change; or with the help of the resonance cavity connected beside the pipeline, so that the noise propagated along the pipeline of a certain frequency is short-circuited in the resonance cavity, and thus can be lowered. Resistant muffler is mainly applied to the muffling of narrow frequency band noise. For the Roots fan, its intake and exhaust noise have obvious broadband characteristics (the low-frequency characteristics of the intake noise appear slightly stronger). Therefore, the muffling effect of the resistant muffler is not as good as that of the resistive muffler...
