解密熔喷布为何选择无油螺杆鼓风机？

随着经济高速发展，我国对越加重视，绿色发展已经逐步成为国民的选择。同时对于环境保护的要求提高，对企业提出了更高的挑战。而螺杆鼓风机作为熔喷布制造过程中的设备，如何选择关系着整个熔喷布厂的运营成本。那为何熔喷布一直都选择了无油螺杆鼓风机呢？我们就来分析下原因。

With the rapid development of economy, China pays more and more attention to environmental protection, and green development has gradually become the national choice. At the same time, the requirements for environmental protection are improved, which puts forward higher challenges for energy saving of enterprises. As the energy-saving equipment in the manufacturing process of melt blown fabric, how to choose the screw blower is related to the operation cost of the whole melt blown fabric factory. Then why does meltblown cloth always choose oil-free screw blower? Let's analyze the reasons.

从压缩原理上来说，螺杆鼓风机属于内压缩的容积式鼓风机。螺杆鼓风机的运行原理是两根平行的阴阳转子在气缸中相互啮合形成工作容积，通过同步齿轮，转子反向运动，容积产生周期性变化，完成内部压缩，将压缩后的气体送消音器排出。

First of all, from the compression principle, screw blower belongs to the internal compression volumetric blower. The operating principle of screw blower is that two parallel male and female rotors mesh with each other in the cylinder to form the working volume. Through the synchronous gear, the rotor moves in reverse, and the volume changes periodically to complete the internal compression, and the compressed gas is sent to the muffler for discharge.

熔喷布作为口罩抵御病毒入侵的核心，通过螺杆挤出设备，让粒子料形成熔融聚合物，压缩空气对模头的喷丝孔挤出来的熔融聚合物进行喷吹，使其拉伸，形成超细短纤维在接收装置上由自身粘合凝聚形成熔喷布。

Melt blown cloth is the core of mask to resist virus invasion. Through screw extrusion equipment, the particles are made into molten polymer. Compressed air is used to blow the molten polymer extruded from the spinneret hole of the die head to stretch it to form ultra-fine short fiber. The melt blown cloth is formed by self adhesion and condensation on the receiving device.

影响熔喷布质量的因素有很多，对于压缩空气来讲，温度、压力等都是关键的影响因素，稍有不对，就无法生产出合格、的熔喷布产品。而无油螺杆鼓风机出气口温度在130°C左右，加热效率高，更。

There are many factors affecting the quality of meltblown cloth. For compressed air, temperature and pressure are the key factors. If something is wrong, it is impossible to produce qualified and safe meltblown cloth products. The outlet temperature of oil-free screw blower is about 130 ° C, which has high heating efficiency and more energy saving.

永磁变频鼓风机压力范围更宽泛，恒压效果更好，满足于现场使用情况。重要的一点是螺杆鼓风机无水无油。

Permanent magnet variable frequency blower has wider pressure range and better constant pressure effect, which can meet the field application. The most important point is that the screw blower has no water and oil.

螺杆鼓风机无水无油，低噪音，大排量等特点，更适合熔喷布市场，所以合理选择适合的无油螺杆鼓风机型号才能达到预期效果与产品质量标准。

Screw blower is water-free, oil-free, low noise, large displacement and other characteristics, which is more suitable for melt blown cloth market. Therefore, reasonable selection of suitable oil-free screw blower model can achieve the expected energy-saving effect and product quality standards.
