一、产品简述
三叶罗茨鼓风机是我厂在吸取国际先进技术基础上自行开发的，结构新颖、低耗能、低噪声、性能优良、维护费用低的新产品。产品开发用了先进的CAD设计手段，先进的工艺和精良的数控设备生产。该产品广泛用于冶金、化工、轻工、建材、纺织、水产养殖、陶瓷业、矿山、塑料、石油、食品、煤气、钢铁、污水处理、气力输送等国民经济各部门。
二、产品特点
1、 流量、压力覆盖面大，应用范围广，质量优良、价格低；
2、 本产品叶轮型线采用特殊复合包络线型，具有齿合好、泄漏少，效率高，压力脉冲小，噪声低；
3、 因转子采用了特殊外形，增强了轴的刚性，提高了风机的升压；
4、 同步齿轮采用优质合金钢经精密加工，有效降低机械传动噪声；
5、 转动件经过严格的平衡，整机几乎没有振动；
6、 整机采用合理的散热结构，有效提高齿轮、轴承的使用寿命；
7、整机设计结构紧凑，结构简单，便于维护和修理。
三 、工作原理
在机体内通过同步齿轮的作用，使两转子相对地呈反方向旋转，由于叶轮相互之间和叶轮与机壳之间皆具有适当的工作间隙，所以构成进气气腔相互。借助转子旋转，形成无内压缩地将机体内气体由进气到排气腔后排出机体，达到鼓风作用。
（1）A轮：进气即将关闭和排气将打开状态； B轮：打开状态。
（2）A轮：已关闭和排气状态；B轮：打开状态。
（3）A轮：打开状态； B轮:进气即将关闭和排气将开状态。
四、LSR型三叶罗茨风机规格：
LSR三叶罗茨风机的规格LSR50,LSR65,LSR80、LSR100、LSR125、LSR150、LSB200,LSR250共8个规格。
风 量： 1.38－77.1m3/min
压 力： 9.8Kpa-78.4Kpa.。
标准附属品：通用底座,皮带罩,风机皮带轮,电机带轮,V形皮带,吸入消声器（带空气滤清器）,安全阀 压力表,润滑油,地脚螺栓
每种型号都有性能表和标准规格，易于选择风机型号。
包括附件在内，风机主体实行标准化。有完善的批量生产体制，能够随时满足您的要求。因为有良好的螺旋结构，又使用同风机匹配的带无声空气滤清器的消声器，风机的运转声音比过去低得多。
转子是经过全面数控加工的精密产品。加工制作时已经取得了完全的动平衡，且没有误差，几乎没有振动。 采取小型设计，安装面积小。
