BSR型罗茨风机是我公司综合国内外同类产品的特点，再投入新技术而开发的新产品。目前该产品已实现系列化设计和批量生产。风机的流量范围是0.5-60m³/min，升压范围：9.8-78.4kpa，共10个机型，100余种规格。

产品特点如下：

    1.该风机采用三叶直线叶轮，排气采用螺旋结构，排气脉动平稳、震动少、噪音低。

    2.叶轮采用特殊的曲线，改善了曲面啮合特性，不仅减少了内泄漏，提高了容积效率，而且能使动态叶轮间隙保持均匀稳定。

    3.齿轮和轴承采用高精度、低噪音设计。叶轮经严格的动平衡检测，且由于压力振幅降低，从而延长风机使用寿命。

    4.采用双油箱结构增加运转的润滑效果，延长各部件的使用寿命。

    5.输送介质不含油，干净清洁，且采用了避免轴承、齿轮油混入机壳内部的密封结构设计。

    BSR Roots blower is a kind of new product developed by our company with new technologies,based on our summarization of the features of the same kinds of products at home and abroad.At present we have realized the serialized design and mass-production of this kind of product.With the flow scope of 0.5-60m³/min and the pressure boost scope of 9.8-78.4kpa,the blowers have more than 100 specifications under 10 types.

Features of Products

    1.The blower uses three-blade linear impellers and adopts a helical structure for exhaust,featured with smooth exhaust pulse,less vibration and low noise.

    2.The impellers adopt the special curve to improve the meshing characteristics of curved surface,which not only reduces the internal leakage and raises the volumetric efficiency but also gets the clearance of dynamic impellers to keep uniform and stable.

    3.Gears and bearings are designed for high precision and low noise.The impellers are tested strictly for dynamic balance and the service life of blowers is prolonged due to lowered pressure amplitude.

    4.Adoption of the twi-oil tank structure raises the lubricating results of turning and prolongs the service life of each component.

    5.Conveying medium contains no oil and boasts cleanness,and a sealing structure is adopted to prevent bearing oil and gear oil from coming into the inner casing.
