气源设备的功能是将自身的机械能传给空气，是空气产生压力差而在输送管道内流动，为气力输送系统提供动力源。常用气力输送气源机械有罗茨风机、水环式真空泵、空气压缩机等。我们先来看一下罗茨风机的工作原理及性能特点。

The function of the air source equipment is to transfer its mechanical energy to the air, and the air flows in the conveying pipe due to the pressure difference, providing the power source for the pneumatic conveying system. The commonly used pneumatic conveying air source machinery includes roots blower, water ring vacuum pump, air compressor, etc. Let's take a look at the working principle and performance characteristics of Roots blower.

（一）工作原理

（1） Working principle

罗茨风机分卧式和历史两种。卧式罗茨风机，由两个渐开腰形转子、长圆形即可、两根平行轴组成。机壳带有水冷、气冷个不舍冷却装置三类。传动机构是在两轴的同端装有式样和大小完全相同的、且互相啮合的两个齿轮，使主动轴直接与电动机相连，并同过齿轮带动使从动轴做相反反向转动。没个转子旋转一周，能挤出两倍体积的空气，因而主动轴每旋转一周就挤出4倍体积空气。罗茨风机进、处口合理的布置应为：闪断进风下端排风，这样可以利用高压气体抵消一部分转子与轴的重力，降低轴承压力，减少磨损。

Roots fans are divided into horizontal and historical types. The horizontal roots blower is composed of two involute waist rotors, oblong rotors and two parallel shafts. The cabinet is equipped with water-cooled and air-cooled cooling devices. The transmission mechanism is equipped with two gears of the same type and size and meshing with each other at the same end of the two shafts, so that the driving shaft is directly connected with the motor, and the driven shaft is driven by the gear to rotate in the opposite direction. Each rotor can extrude twice the volume of air once it rotates, so the driving shaft will extrude 4 times the volume of air once it rotates. The reasonable arrangement of the inlet and outlet of Roots blower shall be as follows: the exhaust at the lower end of the air inlet shall be cut off, so that the high-pressure gas can be used to offset the gravity of part of the rotor and shaft, reduce the bearing pressure and reduce the wear.

1、优点

1. Advantages

正常请况下，压力的变化对风量影响很小，风量主要与风机的转速成正比，因此，罗茨风机基于定容式；

Under normal conditions, the change of pressure has little impact on the air volume. The air volume is mainly proportional to the rotation speed of the fan. Therefore, the Roots fan is basically of constant volume type;

吸气和排气时无脉动不需要缓冲气罐；

There is no pulsation during suction and exhaust and no buffer gas tank is required;

占地面积小，便于布置和安装

Small floor area, convenient for layout and installation

转子与转子之间、转子与课题之间保留0.2-0.5mm的间隙，不存在摩擦现象，允许气流含有一定粉尘；

A gap of 0.2-0.5mm shall be reserved between the rotor and the rotor and between the rotor and the subject, without friction, and the air flow is allowed to contain certain dust;

与水力喷射泵及水环式真空泵相比，不存在“排气带水”问题；

Compared with hydraulic jet pump and water ring vacuum pump, there is no problem of "exhaust with water";

运行可靠，维护方便，耐用。

Reliable operation, convenient maintenance and durability.
