We all know that when roots blower is applied to melt blown cloth, many people don't know the effect. Today's editor will show you the advantages of melt blown roots blower.

　　熔喷布不仅是医疗口罩的应用，在保温防寒、作为过滤材料及吸油材料等方面应用。熔喷布有良好过滤性、屏蔽性、吸油性、绝热性等作用。因此被广泛的应用于卫生医疗、过滤吸油材料等领域。

　　Melt blown cloth is not only the application of medical mask, but also the application of heat preservation and cold prevention, as filter material and oil absorption material. The melt blown cloth has good filtration, shielding, oil absorption, heat insulation and other functions. Therefore, it is widely used in the fields of health care, filtration and oil absorption materials.

熔喷布的材料聚丙烯、聚酯、聚酰胺等化工聚合材料都是熔喷布生产的原材料。将原材料倒入纺丝熔体池里，这个倒入量是经过计量泵严格计算的。随后在高速热风喷射及拉伸作用下，经过喷丝组件将原材料处理成宽度一致，分布均匀的丝束纤维www.bdsh5.com本地生活网。

　　PP, polyester, polyamide and other chemical polymer materials are raw materials for the production of melt blown cloth. The raw material is poured into the spinning melt pool, and the pouring amount is strictly calculated by the metering pump. Then, under the action of high-speed hot air spraying and stretching, the raw materials are processed into tow fibers with uniform width and distribution through the spinneret assembly.

　　压力变化主要是系统阻力的影响，需要自适应强的“风机”，而罗茨风机就自适应强，主要是它没有内压缩，系统的压力值(理想值)一旦确定，只要在电机功率允许范围内，罗茨风机就能够提供多大压力。因此罗茨风机有较好的自适应性。

　　The pressure change is mainly due to the influence of the system resistance, which requires a strong adaptive "fan", while Roots fan is strong adaptive, mainly because it has no internal compression. Once the system pressure value (ideal value) is determined, as long as it is within the allowable range of the motor power, how much pressure can Roots fan provide. Therefore, roots blower has better adaptability.

　　罗茨风机输送的热风量几乎不含油，与罗茨风机的独特构造有关。对于卫生医疗使用的熔喷布来说，是有严格要求的。结束语;除了上述的之外，其结构紧凑、体积小、重量轻、运行平稳、噪音低及振动下，因此很多小企业也是可以实现熔喷布的制造生产的。

　　The hot air delivered by roots blower is almost oil-free, which is related to the unique structure of Roots blower. There are strict requirements for meltblown cloth used in health and medical treatment. Conclusion: in addition to the above, its compact structure, small volume, light weight, stable operation, low noise and vibration, so many small enterprises can also achieve the manufacturing and production of melt blown cloth.

熔喷布罗茨风机安装方法：

　　Installation method of melt blown Roots fan:

　　1.清扫基础混凝土表面,检查其水平度，如不合规定，可以铲平不平的部分原文www.bdsh5.com。

　　1. Clean the surface of foundation concrete and check its levelness. If it does not meet the requirements, the uneven part can be leveled.

　　2.将罗茨鼓风机底座放到基础上，在基础面与底座面之间插入垫铁，其间隙仅需保证灰浆流入即可。用该垫铁调整水平度，使罗茨鼓风机底座处于绝对水平状态。

　　2. Put the roots blower base on the foundation, insert the sizing block between the base surface and the base surface, and the gap between them only needs to ensure the mortar inflow. Use the sizing block to adjust the levelness so that the roots blower base is in an absolute horizontal state.

　　3.安装一般罗茨鼓风机时，亦可准备厚度不同的数种矩形垫铁(钢板以数块重叠进行调整，重要的罗茨鼓风机安装时，因其水平度的要求较高，应使用上下两块为一组的斜垫铁进行调节。采用联轴器传动的罗茨鼓风机可利用联轴器进行检査，调整水平后，再焊接固定。垫铁插进地脚螺栓的两侧，在调整水平的过程中，也有同时采用调整縝栓进行调整的。

　　3. When installing general roots blowers, several kinds of rectangular sizing blocks with different thickness can also be prepared (steel plates shall be adjusted with several overlaps. When installing important roots blowers, because of the high requirement of levelness, the upper and lower sizing blocks shall be used as a group for adjustment. The roots blower driven by coupling can be inspected by coupling, and then welded and fixed after adjusting the level. The sizing block is inserted into both sides of the foundation bolt. In the process of adjusting the level, it is also adjusted by adjusting the meticulous bolt.

　　4.地脚螺栓穿过底座的地脚螺栓孔应垂直于地脚螺栓用方孔内本地生活网。

　　4. The anchor bolt hole through the base shall be perpendicular to the square hole of the anchor bolt.

　　5.地脚螺栓用孔及底座与地基混凝土之间的间隙内，须灌入足够的灰浆，以保证混凝土结构件的强度。

　　5. Sufficient mortar shall be poured into the holes for anchor bolts and the gap between the base and the foundation concrete to ensure the strength of the concrete structure.

　　安装重要或精度要求较高的罗茨鼓风机时，应先把灰浆灌人埋设地脚螺栓的孔内，待其充分硬化后,重新找正、调整为水平，在达到安装精度要求后，再将灰浆灌入底座与地基混凝土之间的间隙。

　　When installing the important or high precision roots blower, the mortar shall be poured into the hole where the anchor bolt is embedded, and after it is fully hardened, the mortar shall be aligned and adjusted to the level again. After the installation accuracy requirements are met, the mortar shall be poured into the gap between the base and the foundation concrete.
6.等到灰浆充分硬化后，紧固地脚螺栓的螺母。

　　6. After the mortar is fully hardened, tighten the nuts of the anchor bolts.

　　7.灌浆工序对于在整个罗茨鼓风机安装过程相当重要。它不仅对底座与地基混凝土间的空间起作用，而且对罗茨鼓风机负载的传递、机械刚度的辅助也有较大影响。故在施工时，应特别注意泥浆的收缩性和断裂性，采取合理的施工方法b+d+s+h+5+c+o+m。

　　7. Grouting process is very important in the whole installation process of Roots blower. It not only plays a role in the space between the base and the foundation concrete, but also has a great influence on the load transfer of Roots blower and the assistance of mechanical stiffness. Therefore, during the construction, special attention should be paid to the shrinkage and fracture of the mud, and reasonable construction methods should be adopted.

　　8.一般的大型罗茨鼓风机，机壳与底座是分开的。对于剖分式罗茨鼓风机，其机壳是分为几部分的。安装时，首先按照上述方法安装好罗茨鼓风机底座和轴承底座后，再按照下机壳、转子、上机壳的顺序，边调整定子与转子之间的间隙,边进行组装。

　　8. For general large roots blower, the shell and base are separated. For split roots blower, its shell is divided into several parts. During installation, first install the roots blower base and bearing base according to the above method, then adjust the clearance between the stator and the rotor according to the sequence of the lower casing, the rotor and the upper casing, while assembling.

　　9.有些情况下，因无法设置足够的地基，常常将罗茨鼓风机安装在减振器上,以减轻振动的传递力，减振器应以罗茨鼓风机的重心为中心进行布置，保证各减振器的压缩量一致。

　　9. In some cases, due to the insufficient foundation, roots blower is often installed on the vibration damper to reduce the transmission force of vibration. The vibration damper shall be arranged with the center of gravity of Roots blower as the center to ensure the same compression amount of each vibration damper.
熔喷布罗茨风机选型参数：

　　Model selection parameters of melt blown Roots fan:

　　1.风机的流量

　　1. Fan flow

　　鼓风机的选型主要参数是流量参数，知道流量参数之后，能够进行大概的型号确定，但是还不能确定具体的型号，还需要省下面的参致。

　　The main parameters of blower selection are flow parameters. After knowing the flow parameters, you can determine the approximate model, but you can't determine the specific model. You need to save the following parameters.

　　2.风机的压力

　　2. Fan pressure

　　风机的压力决定电机的型号，电机功率大，就选大一些的型号，电机功率小，就选小功率的电机，电机的型号会直接影响到风机的价档，所以，压力需计算好bdsh5.com。

　　The pressure of the fan determines the model of the motor. If the motor power is large, select a larger model. If the motor power is small, select a small power motor. The model of the motor will directly affect the price of the fan. Therefore, the pressure needs to be calculated well.

　　3.其他参数

　　3. Other parameters

　　其他参数能够影响到罗次风机的有：气体温度、海拔高度、密封方式等，这些也会影响到风机的逃型配置，但是综合来说递型还是失营风量和压力参致，当然，提供的需求信息越充足，选型越合理，使用效果更加满足生产需要。

　　Other parameters can affect the air temperature, altitude, sealing mode, etc. of the Roots fan, which will also affect the escape configuration of the fan. However, generally speaking, the recurrence type is still the loss of operating air volume and pressure parameter. Of course, the more sufficient demand information is provided, the more reasonable the model selection is, and the use effect more meets the production needs.

　　相信大家看完以上内容以后，应该也对熔喷布罗茨风机的使用效果有所了解了，希望会对大家有所帮助吧。

　　I believe that after reading the above content, you should also have an understanding of the use effect of the melt blown Roots fan. I hope it will help you.
