氣源設(shè)備的功能是將自身的機(jī)械能傳給空氣,，是空氣產(chǎn)生壓力差而在輸送管道內(nèi)流動,，為氣力輸送系統(tǒng)提供動力源,。常用氣力輸送氣源機(jī)械有羅茨風(fēng)機(jī)、水環(huán)式真空泵,、空氣壓縮機(jī)等,。我們先來看一下羅茨風(fēng)機(jī)的工作原理及性能特點。

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

羅茨風(fēng)機(jī)分臥式和歷史兩種。臥式羅茨風(fēng)機(jī),，由兩個漸開腰形轉(zhuǎn)子,、長圓形即可、兩根平行軸組成,。機(jī)殼帶有水冷,、氣冷個不舍冷卻裝置三類。傳動機(jī)構(gòu)是在兩軸的同端裝有式樣和大小完全相同的,、且互相嚙合的兩個齒輪,，使主動軸直接與電動機(jī)相連，并同過齒輪帶動使從動軸做相反反向轉(zhuǎn)動,。沒個轉(zhuǎn)子旋轉(zhuǎn)一周,，能擠出兩倍體積的空氣,，因而主動軸每旋轉(zhuǎn)一周就擠出4倍體積空氣。羅茨風(fēng)機(jī)進(jìn),、處口合理的布置應(yīng)為：閃斷進(jìn)風(fēng)下端排風(fēng),，這樣可以利用高壓氣體抵消一部分轉(zhuǎn)子與軸的重力，降低軸承壓力,，減少磨損。

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,、優(yōu)點

1. Advantages

正常請況下，壓力的變化對風(fēng)量影響很小,，風(fēng)量主要與風(fēng)機(jī)的轉(zhuǎn)速成正比，因此,，羅茨風(fēng)機(jī)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;

吸氣和排氣時無脈動不需要緩沖氣罐,；

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

占地面積小,，便于布置和安裝

Small floor area, convenient for layout and installation

轉(zhuǎn)子與轉(zhuǎn)子之間、轉(zhuǎn)子與課題之間保留0.2-0.5mm的間隙,，不存在摩擦現(xiàn)象,，允許氣流含有一定粉塵,；

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;

與水力噴射泵及水環(huán)式真空泵相比，不存在“排氣帶水”問題,；

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

運行可靠，維護(hù)方便,，耐用,。

Reliable operation, convenient maintenance and durability.
