罗茨鼓风机系属容积回转鼓风机。这种压缩机靠转子轴端的同步齿轮使两转子保持啮合。转子上每一凹入的曲面部分与气缸内壁组成工作容积，在转子回转过程中从吸气口带走气体，当移到排气口附近与排气口相连通的瞬时，因有较高压力的气体回流，这时工作容积中的压力突然升高，然后将气体输送到排气通道。两转子互不接触，它们之间靠严密控制的间隙实现密封，故排出的气体不受润滑油污染www.bdsh5.com本地生活网。
Roots blower is a volume rotary blower. This kind of compressor relies on the synchronous gear at the shaft end of the rotor to keep the two rotors engaged. Each concave curvedsurface part of the rotor and the inner wall of the cylinder form a working volume. During the rotation of the rotor, the gas is taken away from the suction port. When it is moved tothe exhaust port and connected with the exhaust port, the pressure in the working volume suddenly rises due to the backflow of the gas with higher pressure, and then the gas isdelivered to the exhaust channel. The two rotors are not in contact with each other, and they are sealed by tightly controlled clearance, so the discharged gas is not polluted bylubricating oil.
罗茨鼓风机属容积式风机，叶轮端面、风机前后端盖。原理是利用两个叶形转子在气缸内作相抄对运动来压缩和输送气体的回转压缩机。这种鼓风机结构简单，制造方便，广泛应用于水产养殖增氧、百污水处理曝气、水泥输送，更适用于低压力场合的气体输送和加压系统，也可用作真空泵等度。机壳与墙板均具有良好的刚度，在机体的外表面及底部均有合理布置的加强机壳和墙板有自然空气冷却和水冷却结构两种。考虑到鼓风机的排气温度是随风机的吸人气体温度及排气压力的大小而变化的本地生活网www.bdsh5.com。
Roots blower is a positive displacement fan with impeller end face and front and rear end covers. The principle is a rotary compressor which uses two vane rotors to make oppositemovement in the cylinder to compress and transport gas. The blower is simple in structure and convenient in manufacture. It is widely used in the aeration of aquaculture, sewagetreatment, cement transportation, gas transportation and pressure system in low pressure situation, and also as vacuum pump. The shell and the wall panel have good rigidity, and thereare two kinds of reinforced shell and the wall panel with reasonable arrangement on the outer surface and the bottom of the body: natural air cooling structure and water coolingstructure. Considering that the exhaust temperature of the blower varies with the suction gas temperature and exhaust pressure of the blower.
实践证明，当吸入空气温度为40℃，排气压力为60kPa时，排气温度高达100C左右。因此，排气压力大于50kPa时风 机采用有水夹层的冷却方式冷却机体及介质。排气压力小于50kPa时，机体采用自然冷却。罗茨鼓风机墙板是机壳的两侧，墙板内装密封件和轴承座，作为风机支承，同机壳结合在一起构成一密闭气缸。对立式鼓风机墙板均采用整体式结构，轴承座与密封均在同整体结构内，对卧式鼓风机墙板均采用组合式结构，即墙板分成上、下两部分，下部分是一块，上部分开成两块，密封与轴承座间隔开，隔开部分外露b d s h 5 c o m。对输送易腐蚀介质，如前面两种结构都采用同-密封结构，密封性较差时，则腐蚀性介质泄漏后会排到外面而不会直接进入轴承。所以后种结构轴承受到腐蚀损坏较慢，相对轴承寿命较长，而前者由于腐蚀性介质直接进人轴承，损坏较快，寿命较短。
It has been proved that when the temperature of the intake air is 40 ℃ and the exhaust pressure is 60 kPa, the exhaust temperature is up to about 100C. Therefore, when theexhaust pressure is greater than 50kPa, the fan adopts the cooling method with water interlayer to cool the body and medium. When the exhaust pressure is less than 50kPa, the body iscooled naturally. The wall panel of Roots blower is the two sides of the shell. The wall panel is equipped with seals and bearing blocks, which are used as the fan support andcombined with the shell to form a sealed cylinder. The wall panel of vertical blower adopts integral structure, bearing seat and seal are in the same integral structure, and the wallpanel of horizontal blower adopts combined structure, that is, the wall panel is divided into upper and lower parts, the lower part is one, the upper part is two, the seal and bearingseat are separated, and the separated part is exposed. For the transportation of corrosive media, if the former two structures adopt the same sealing structure, the corrosive mediawill be discharged if the sealing is poorAfter leakage, it will be discharged to the outside without directly entering the bearing. Therefore, the shaft of the latter kind ofstructure bears slower corrosion damage and has a longer service life compared with the bearing, while the former is damaged faster and has a shorter service life due to the corrosivemedium entering the bearing directly.
罗茨鼓风机过滤棉在更换时,可以选择从原厂采购,也可以选择从经销商处采购,为了保证过滤精度一致,建议广大客户选择从厂家进行选择,只要将设备的型号报给厂家,厂家就会为我们发配相应精度的滤芯.负压稀相气力输送系统采用罗茨鼓风机或真空泵作为气源设备,取料装置部件通常为吸料枪、体积喂料机,气源设备装在系统的末端,当风机运转后,整个系统形成负压,由管道内外存在的压力差空气被吸入输料管.与此同时物料和一部分空气便同时被吸嘴吸入,并被输送到真空上料器,在真空上料器中,物料和空气分离,被分离出来的物料由从真空上料器底部卸出,而未被分离出来的微细粉粒随气流进入除尘器中净化,净化后的空气经除尘器排入大气.
When replacing the filter cotton of Roots blower, you can choose to purchase it from the original factory or from the dealer. In order to ensure the same filtering accuracy, it isrecommended that the majority of customers choose from the manufacturer. As long as the model of the equipment is reported to the manufacturer, the manufacturer will provide us withthe filter element negative pressure dilute phase pneumatic conveying system with roots blower or vacuum pump as the air source equipment, The components of the reclaiming device areusually the suction gun and the volume feeder. The air source equipment is installed at the end of the system. When the fan is running, the whole system will form a negative pressure,and the pressure difference air inside and outside the pipe will be drawn into the conveying pipe. At the same time, the material and part of the air will be drawn into the suctionnozzle at the same time, and will be delivered to the vacuum feeder. In the vacuum feeder, the material and air will be separated, The separated materials are discharged from thebottom of the vacuum feeder, while the fine powder particles that are not separated enter the dust remover with the air flow for purification, and the purified air is discharged intothe atmosphere through the dust remover
负压稀相气力输送的优势在于易于取料,适用于要求取料不发尘的场合;适用于从低处、深处、狭窄取料点以及由几处向一处集中送料的场合;由于气源设在系统的末端,润滑油或水分等不会混入被输送的物料;由于输料管系统内压力低于大气压力,所以即使产生磨损和存在间隙时,被输送物料也不会泄露;由于输送系统内压力低于大气压力,水分易蒸发,所以对水分多的物料也较压送式容易输送.
The advantage of negative pressure dilute phase pneumatic conveying is that it is easy to take materials, and it is suitable for the occasions where it is required to takematerials without dust generation; it is suitable for the occasions where the materials are taken from low, deep, narrow and concentrated places; because the air source is set at theend of the system, the lubricating oil or water will not mix into the transported materials; because the pressure in the conveying pipe system is lower than the atmospheric pressure,Therefore, even if there is wear and clearance, the transported materials will not leak; because the pressure in the conveying system is lower than the atmospheric pressure, the wateris easy to evaporate, so the materials with more water are easier to transport than the pressure conveying type
墙板是机壳的两侧，墙板内装密封件和轴承座，作为风机支承，同机壳结合在一起构成密闭气缸，对立式鼓风机墙板均采用整体式结构，轴承座与密封均在同一整体结构内，对卧式鼓风机墙板均采用组合式结构，即墙板分为上、下两部分，下部分是一面两种结构都采用同一种密封结构，密封性较差时，则腐蚀性介质泄漏后会排到外面而不会直接进入轴承。所以后一种密封轴承收到腐蚀损坏较慢，相对轴承寿命较长，而前者由于腐蚀性介质直接进入轴承，损坏较慢，寿命较短。罗茨鼓风机齿轮与轴采用精度较高的过渡配合，固定齿轮用的键采用特殊公差配合，防止齿轮键松动，使齿轮能够紧密的固定在轴上，以避免一旦齿轮松动后，使齿轮侧隙增大，已致两叶轮会发生碰撞现象bdsh5.com。
The wallboard is the two sides of the shell. The wallboard is equipped with seals and bearing blocks. It is used as the fan support and combined with the shell to form a sealedcylinder. The wallboard of vertical blower adopts an integral structure. The bearing blocks and seals are in the same integral structure. The wallboard of horizontal blower adopts acombined structure, that is, the wallboard is divided into two parts: the upper part and the lower part. The lower part is one side and two structures With the same sealing structure,when the sealing performance is poor, the corrosive medium will be discharged to the outside and will not enter the bearing directly after leakage. Therefore, the corrosion damage ofthe latter kind of sealed bearing is slow and its service life is relatively long, while the former is relatively short because the corrosive medium enters the bearing directly. Thegear and shaft of Roots blower adopt high precision transition fit, and the key used to fix the gear adopts special tolerance fit to prevent the gear key from loosening, so that thegear can be tightly fixed on the shaftOnce the gear is loose, the backlash of the gear will increase, which will cause collision between the two impellers.
一般情况下，如是额定负载的话，那是非常正常的，如是超负载的话，那就完全不正常了。比如在罗茨风机工作运行一切正常，是不能完全的关闭进排气口的阀门的，更不用说超负荷的运行了，这更不准了。有些工厂用的是鼓风机，那么鼓风机的话，尽量不要满负荷的突然停车，是逐步的来卸载后在停车，这可避免机器的损坏。由于它的特性，更不允许在排气口的气体长时间回流到进气口中，这对机器油影响，当遇到这种情况需采取冷却措施。
In general, if it is rated load, it is very normal, if it is overload, it is completely abnormal. For example, when the roots blower works normally, it can't completely close thevalve at the inlet and outlet, let alone the overload operation, which is even more inaccurate. Some factories use blowers. If blowers are used, try not to stop suddenly at full load,but stop after unloading gradually, which can avoid damage to the machine. Due to its characteristics, it is not allowed that the gas in the exhaust port flows back to the air inletfor a long time, which has an impact on the machine oil. In this case, cooling measures should be taken.
