羅茨鼓風機的電動機通過V型帶(或聯(lián)軸器)帶動主動軸，由主動軸通百過齒輪箱內的同步齒輪的作用，使機體內的兩三葉型葉輪呈反方向旋轉。葉輪相互之間及葉輪與機體之間有一定的工作隙，當兩葉輪旋轉時，則無內壓縮地將機體內的氣度體由進氣腔推送至排氣腔后排出機體，達到曝氣作用。羅茨鼓風機作為回轉式機械，具有比較穩(wěn)定的工作特性，羅茨鼓風機轉子與轉子、轉子與泵體、轉子與側蓋之間都有微小間隙，因而工作腔內沒有摩擦，無接觸磨損部分；三葉羅茨鼓風機經(jīng)濟耐用，內無需潤滑，使用壽命長，動力平衡性好。運轉一周有六次吸排氣過程，容積效率高。結構簡單，使用維護方便，不需要內部潤滑，輸送的介質不含油等特點。不僅節(jié)省了維修費用，還增加了使用壽命，這樣的節(jié)容能效果顯著。

　　The electric motor of the Roots blower drives the active shaft through a V-belt (or coupling), and the two or three blade impellers inside the machine rotate in the opposite direction through the synchronous gear inside the gearbox. There is a certain working gap between the impellers and between the impellers and the body. When the two impellers rotate, they push the air mass inside the body from the intake chamber to the exhaust chamber without internal compression, and then discharge it from the body, achieving aeration. As a rotary machinery, Roots blower has relatively stable working characteristics. There are small gaps between the rotors of Roots blower, rotor and pump body, and rotor and side cover, so there is no friction or contact wear in the working chamber; Three leaf Roots blower is economical and durable, does not require lubrication inside, has a long service life, and has good power balance. Running six times a week for suction and exhaust processes, with high volumetric efficiency. The structure is simple, easy to use and maintain, does not require internal lubrication, and the conveyed medium does not contain oil. Not only does it save maintenance costs, but it also increases the service life, which has a significant energy-saving effect.

　　1.想要高壓羅茨鼓風機省電高效，至關重要的一點就是合理選擇高壓羅茨鼓風機型號，選擇合適其工作環(huán)境應配置的風壓風量等參數(shù)信息，不使高壓羅茨鼓風機在低效區(qū)進行。

　　1. In order to save energy and improve efficiency of high-pressure Roots blowers, it is crucial to choose a reasonable model of high-pressure Roots blower, select appropriate parameters such as wind pressure and air volume that should be configured for its working environment, and avoid operating the high-pressure Roots blower in low efficiency areas.

　　2.盡量減小管網(wǎng)的阻力，合理選擇管道的尺寸以及管道的安裝位置，集流器的配備上也是建議選用質量優(yōu)等的進口集流器。

　　2. Try to minimize the resistance of the pipeline network, choose the size and installation position of the pipeline reasonably, and it is also recommended to use high-quality imported collectors for the installation of collectors.

　　3.對于單獨適用的高壓羅茨鼓風機葉輪，一定要配備合適的風機專用的電機，從根源上避免出現(xiàn)電機設備輸出的功率與用負荷不成比例的大馬拉小車的現(xiàn)象。

　　3. For high-pressure Roots blower impellers that are individually applicable, it is necessary to equip them with suitable fan specific motors to avoid the phenomenon of large horses pulling small cars out of proportion between the output power of the motor equipment and the load from the root.

　　4.風筒與葉片頂部的徑向間距也是影響高壓羅茨鼓風機耗電情況的一個因素，一定要合理控制。羅茨鼓風機運行中的摩擦原因：

　　4. The radial distance between the air duct and the top of the blades is also a factor that affects the power consumption of high-pressure Roots blowers, and must be controlled reasonably. Friction reasons during the operation of Roots blower:

　　羅茨鼓風機在運轉過程中注意事項是羅茨鼓風機運轉過程中，須經(jīng)常檢查軸承。羅茨鼓風機設備中潤滑油溫度。電流表的示值。羅茨鼓風機需用冷卻水時應檢查冷卻水量是否達到規(guī)定的要求。風機有填料密封時，還應檢查密封的泄漏情況，當泄漏嚴重時，應立即更換密封，以免危險氣體泄漏引發(fā)安全事故，且腐蝕氣體的泄漏也會損壞軸承。

　　The precautions during the operation of Roots blower are to regularly check the bearings. Lubricating oil temperature in Roots blower equipment. The reading of the ammeter. When the Roots blower requires cooling water, it should be checked whether the cooling water volume meets the specified requirements. When the fan has a packing seal, the leakage of the seal should also be checked. When the leakage is severe, the seal should be replaced immediately to avoid safety accidents caused by dangerous gas leakage, and the leakage of corrosive gas can also damage the bearings.

　　羅茨鼓風機運轉中須注意電流表的示值，如出現(xiàn)異常應立即停車檢查，其原因大多是由版葉輪摩擦引起的。不要以為運轉中的羅茨鼓風機不需要看著，恰恰相反更應該好好地看著，要不稍微不注意就會造成風機的損壞，影響正常的權使用。

　　During the operation of the Roots blower, attention should be paid to the reading on the ammeter. If any abnormalities occur, the machine should be stopped immediately for inspection. The cause is mostly due to the friction of the impeller. Don't think that the Roots blower in operation doesn't need to be watched, on the contrary, it should be watched carefully, otherwise a slight carelessness can cause damage to the fan and affect normal use.

　　羅茨鼓風機的構造結構簡單，機殼內只有兩個轉子，運行中的摩擦現(xiàn)象可分為三類：即轉子相互之間的摩擦、兩轉子與外殼的摩擦、兩轉子端面與壁板的摩擦，其摩擦原因如下：

　　The structure of Roots blower is simple, with only two rotors inside the casing. Friction phenomena during operation can be divided into three categories: friction between rotors, friction between rotors and the casing, and friction between rotor end faces and wall panels. The reasons for friction are as follows:

　　1.軸的剛性不夠。羅茨鼓風機在旋轉時，若主、從動軸的剛性不夠，產(chǎn)生了扭轉變形(此變形是在彈性限度以內)，而使兩轉子之間或轉子與機殼之間產(chǎn)生摩擦。此時，應對軸重新處理，提高剛性或更換剛性強的軸。

　　1. The rigidity of the shaft is insufficient. When the Roots blower rotates, if the rigidity of the main and driven shafts is not sufficient, torsional deformation occurs (this deformation is within the elastic limit), causing friction between the two rotors or between the rotor and the casing. At this point, the shaft should be reprocessed to increase rigidity or replaced with a shaft with stronger rigidity.

　　2.齒輪磨損。特別是鼓風機兩轉子水平放置時，由于齒輪磨損以后，使兩轉子位置發(fā)生了變化，致使兩轉子之間摩擦。此時，應檢修齒輪或更換新齒輪。

　　2. Gear wear. Especially when the two rotors of the blower are placed horizontally, the position of the two rotors changes due to gear wear, resulting in friction between the two rotors. At this point, the gears should be inspected or replaced with new ones.

　　3.齒輪鍵槽與鍵松動。由于鍵槽與鍵發(fā)生了松動，也會使兩轉子位置變化，而使轉子之間產(chǎn)生摩擦。此時，應修理鍵或換新鍵，使之不松動。

　　3. The gear keyway and key are loose. Due to the loosening of the keyway and key, it can also cause a change in the position of the two rotors, resulting in friction between the rotors. At this point, the key should be repaired or replaced to prevent it from loosening.

　　4.軸承間隙超過規(guī)定的技術要求，輸送氣體中有硬性雜質，都會引起轉子之間的摩擦。此時，應重新調整軸承間隙或清除氣體中雜質。

　　4. Bearing clearance exceeding the specified technical requirements and the presence of hard impurities in the transported gas can cause friction between rotors. At this point, the bearing clearance should be readjusted or impurities in the gas should be removed.
