螺杆鼓风机的工作原理及结构特点

螺杆鼓风机分为单螺杆与双螺杆式，市场上常见的为双螺杆鼓风机。双螺杆结构在鼓风机领域才开始获得较快发展，并在诸多应用领域展现里良好的易用性，如、稳定等。凭借良好的性能，在较多领域开始逐渐替代罗茨等传统风机。

Screw blower is divided into single screw and twin-screw type, the common in the market is twin-screw blower. The twin-screw structure in the field of blowers began to obtain rapid development, and in many applications show good ease of use, such as energy saving, stability and so on. With the good performance of roots, more and more fans began to replace.

无油螺杆鼓风机一般主要由外罩、主机、电机、空气过滤器、消音器、油泵油箱以及油虑等部分构成。双螺杆鼓风机可根据客户要求进行定制，比如去掉外罩、改为无油系统等。

The oil-free screw blower is generally composed of cover, main engine, motor, air filter, muffler, oil pump tank and oil filter. Twin screw blower can be customized according to customer requirements, such as removing the cover, changing to oil-free system, etc.

螺杆主机作为螺杆风机的核心部件，其结构直接决定了风机性能的优劣。螺杆主机主要由机壳、螺杆转子、齿轮箱、轴承、轴封等主要部件构成。

As the core component of screw fan, the structure of screw host directly determines the performance of the fan. Screw host is mainly composed of casing, screw rotor, gearbox, bearing, shaft seal and other main components.

与罗茨风机等不同，无油螺杆鼓风机在腔体内气体输送的过程中实现了内压缩，因此螺杆拥有罗茨大部分的优点之外，同时比罗茨具备更高的效率，且气体的输送压缩的过程是连续渐进的，气流脉动更低，排气噪音、温度控制等均要优于罗茨等传统风机。

Different from roots blower, the oil-free screw blower achieves internal compression in the process of gas transportation in the cavity. Therefore, the screw has most of the advantages of roots, and has higher efficiency than roots. Moreover, the process of gas transportation and compression is continuous and gradual, with lower flow pulsation, better exhaust noise and temperature control than roots and other traditional fans.

螺杆鼓风机：率，低噪音和无油空气 绿色，在和工业生产的众多领域，均需要使用到提供低压空气的鼓风机产品，而领域里，废水排放和空气排放都要用到无油螺杆鼓风机，无论是市政污水还是企业污水（包括：纺织印染，皮革，化工，造纸，养殖等领域）

oil free screw blower: high efficiency, low noise and oil-free air Green, energy-saving and environmental protection, in many fields of environmental protection and industrial production, blower products that provide low-pressure air are needed. In the field of environmental protection, oil-free screw blower is used for wastewater discharge and air discharge, whether it is municipal sewage or enterprise sewage (including textile printing and dyeing, leather, chemical industry, papermaking, breeding, etc.)
