螺桿鼓風機的工作原理及結構特點

螺桿鼓風機分為單螺桿與雙螺桿式，市場上常見的為雙螺桿鼓風機。雙螺桿結構在鼓風機領域才開始獲得較快發展，并在諸多應用領域展現里良好的易用性，如節能、穩定等。憑借良好的性能，在較多領域開始逐漸替代羅茨等傳統風機。

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.

無油螺桿鼓風機一般主要由外罩、主機、電機、空氣過濾器、消音器、油泵油箱以及油慮等部分構成。雙螺桿鼓風機可根據客戶要求進行定制，比如去掉外罩、改為無油系統等。

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.

螺桿主機作為螺桿風機的核心部件，其結構直接決定了風機性能的優劣。螺桿主機主要由機殼、螺桿轉子、齒輪箱、軸承、軸封等主要部件構成。

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.

Characteristics of screw blower

與羅茨風機等不同，無油螺桿鼓風機在腔體內氣體輸送的過程中實現了內壓縮，因此螺桿擁有羅茨大部分的優點之外，同時比羅茨具備更高的效率，且氣體的輸送壓縮的過程是連續漸進的，氣流脈動更低，排氣噪音、溫度控制等均要優于羅茨等傳統風機。

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.

螺桿鼓風機：高效率，低噪音和無油空氣 綠色節能環保，在環保和工業生產的眾多領域，均需要使用到提供低壓空氣的鼓風機產品，而環保領域里，廢水排放和空氣排放都要用到無油螺桿鼓風機，無論是市政污水還是企業污水（包括：紡織印染，皮革，化工，造紙，養殖等領域）

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.)
