羅茨風機由于是高速運轉的機器，所以會產生震動，又由于其內部空氣的脈動左右，也加大了羅茨風機的震動，所以羅茨風機的安裝時需要固定在地面上的。根據風機型號不同，在地面按風機尺寸在對應的位置挖150*150mm見方300mm深的方坑，并埋入地腳螺栓，然后通過螺栓，螺母把風機連接起來，**在方坑中填滿水泥混凝土，等混凝土固定之后，再用力把螺母擰緊，是風機底座和混凝土牢牢連接在一起，這樣就可以減小羅茨風機在運轉中的震動位移，提高了設備的運行安全性，并且由于減小了震動，從而也大大延長了風機的使用壽命。

　　1、電源線安裝問題

　　在給羅茨風機接線時，應當符合風機的額定工作電壓，使用的是380V的電壓，不得接成220V的工作電壓。電線也不得接反，接反之后，風機就會出現反轉的情況，如果在試運行時風機轉向不對，一定進行排查，如果排查不出來，接裝上管道之后，設備就會短時間內出現損壞。如：我們曾有一位客戶就是因為電線接反，試運行沒有檢測出來，導致風機在運行了10分鐘左右就出現了嚴重的損壞。

　　2、安裝平臺問題

　　一般來說，羅茨風機應當安裝于高于地面之上的平臺上，但是需要根據實際情況而定，有些小型號的羅茨風機不需要進行固定，而有些型號的羅茨風機必須進行加裝固定，置于室內的羅茨風機，我們建議根據實際情況安裝，可安裝在平臺上面也可以安裝在地面上面。而置于外界的羅茨風機，我們建議安裝于平臺上面，安置于平臺上能有效的避免一些外界侵蝕。

　　3、安裝時的海拔問題

　　如果我們有兩處分廠，兩處的海拔懸殊較大，則兩者之間的羅茨風機不得進行互換使用，海拔不同，同一型號的羅茨風機不能互相替用。在羅茨風機選型的時候，我們也需要根據海拔來確定羅茨風機的型號，確保能夠正常使用。

　　4、安裝時的開關問題

　　一般來說，開關不得遠離設備，設備遠離我們之后，一旦出現故障，控制起來不方便，故障時間延長越久，設備損壞越大。

　　5、安裝時的氣流問題

　　我們在安裝羅茨風機時，周邊環境**不要有強風，不管是逆風還是順風，都會影響到設備的吸排氣效果，所以，控制好風機周邊的氣流循環能夠有效的延長羅茨風機的使用壽命。

　　羅茨風機安裝：

　　羅茨風機在出廠前是安裝好，只需要將進口消音器與入口相連，出口消音器與出口相連，再將出口消音器與管道相連即可。下面說說安裝注意事項：

　　1、羅茨風機應安裝在地面結實堅固的場所，周圍應留有充分的余地，便于檢查、維護、保養。

　　2、羅茨風機底座下應保持地基水平，底座四角處建議墊減震橡皮或用螺栓澆制安裝，確保羅茨風機運轉平穩，振動小。

　　3、羅茨風機與系統的連接管道應密封可靠，對小真空泵可采用金屬管路連接密封墊采用耐油橡膠，對小羅茨風機可采用真空膠管連接，管道管徑不得小于羅茨風機吸氣口徑，且要求管路短而少彎頭。(焊接管路時應清除管道中焊渣，嚴禁焊渣進入真空泵腔。)

　　4、在連接管路中，用戶可在羅茨風機進氣口上方安裝閥門及真空計，隨時可檢查羅茨風機的極限壓力。

　　5、按電動機標牌規定連接電源，并接地線和安裝合適規格的熔斷器及熱繼電器。

　　6、羅茨風機通電試運轉時，須取下電機皮帶，確認真空泵轉向符合規定方向方可投入使用，以羅茨風機反轉噴油。(轉向按防護罩指示方向)

　　7、對于有冷卻水的羅茨風機，按規定接通冷卻水。

　　8、如羅茨風機口安裝電磁閥時，閥與羅茨風機應同時動作。

　　9、當羅茨風機排出氣體影響工作環境時，可在排氣口裝接管道引離或裝接油霧過濾器。

　　羅茨風機的調試：

　　羅茨風機調試分：點動調試、空載運行調試，全壓調試，全系統調試。

　　1、點動調試是指在現場，將風機與系統完全脫離，斷開風機的進出風口管道連接。手動盤車，確認機體內部沒有卡頓后，啟動風機，隨后立即關閉，然后觀察風機的旋轉方向與機體標注的旋轉方向是否相同，如果不同，對于三相電機，交換任意兩相的電纜，重新連接即可。因為羅茨風機的結構，是不能反轉的。

　　2、空載運行調試，是指在繼承上一步驟，確認風機旋轉方向正確的前提下，啟動風機，連續運行半小時，觀察風機的運行是否穩定，有無異常噪音、震動。

　　3、全壓測試，是指在風機出口安裝一閥門(為避免噪聲，當在閥門后連接一消音器)，啟動風機后，通過逐步關閉閥門，對風機施加模擬負載，直至風機壓力達到銘牌所示的壓力，隨后連續運行2小時左右，確保風機是否沒有異響，溫度穩定(風機加壓后溫度逐步上升，一般短則半小時，長則2小時，溫度趨于穩定停止上升，如繼續上升，多半存在問題)，以及風機電流在銘牌所示范圍之內。

　　4、全系統測試，是指將風機接入工作系統內，開始試運行，試運行當維持半小時以上。由于設計一般放有設計余量，故風機接入系統后，實際運行之壓力電流，都應當低于銘牌所示壓力，如出現超載工況則往往意味著選型失當，需要嚴格排查分析問題。

　　快速降低三葉羅茨風機軸承溫度的方法：

　　三葉羅茨鼓風機的軸承溫度也會受到外界環境影響，冬季時室溫較低，三葉羅茨鼓風機運行狀況良好(室溫5℃時，三葉羅茨鼓風機前軸承在80℃左右)，而到了夏季，當室溫達到30℃以上時，三葉羅茨鼓風機前軸承隨著室溫上升超過設定跳閘溫度。為避免跳閘，機組人員在機殼上加裝噴淋水降溫作為應急處理方法，但運行中衛生狀況較差，現在推薦幾種簡單快速的方法。

　　1.簡單符合實際的就是在風機外部加裝遮陽板，這是降溫的直接方法之一。

　　2.如果軸流風機、耐磨風機等風機溫度升過高，很可能是風機開車時進、出氣管道閘門未關造成的。解決辦法：關閉進、出氣管道閘門就行了。

　　3.另外由于箱體劇烈振動造成的，軸與滾動軸承安裝歪斜、前后兩軸承不同心，風機滾動軸承損壞或軸彎曲，都是影響風機軸承溫度的因素之一，解決方法：及時更滑潤滑油減少摩擦系數。

　　4.電機皮帶過松，在這里應注意及時更換電機皮帶，調整好皮帶輪的位置使其受力均勻。

　　以上就是三葉羅茨風機組裝注意事項和步驟和快速降低軸承溫度方法。

　　羅茨風機的組裝順序：

　　羅茨風機借助與兩葉輪的嚙合，將進氣口和出氣口相互隔開，過程中無內壓地將氣缸容積內的氣體從進氣口推移到出氣口，以達到強制排氣的目的。羅茨風機在使用之前都要先進行組裝，這樣才能保證它的正常運行。

　　1.將機殼吊到工作臺上、吹洗、修毛刺。

　　2.將驅動端的墻板安裝在機殼上。

　　3.將轉子從另一端推入機殼中。

　　4.組裝齒輪端側墻板;并保證軸向總間隙，總間隙不夠可選配機殼密封墊。

　　5.組裝兩側軸承座、軸承。決定葉輪軸向分配間隙。

　　6.組裝齒輪部分，甩油盤。注意按打上的標記校對。齒輪的錐面不許涂油，應清洗干凈。

　　7.組裝齒輪箱。

　　羅茨風機如何安全運行：

　　1.檢查羅茨風機各部分的緊固性，以及定位銷是否出現松動現象。如果松動，則必須將其緊固。

　　2.風機體內不應有水垢、銹蝕和剝落現象。防止出現滲漏現象。

　　3.拆卸機器時，請測量機器的匹配尺寸，進行記錄并標記和引導零件，以確保組裝并保持原始的匹配要求。

　　4.有時無法立即顯示羅茨風機的過載情況，因此請注意進氣和排氣壓力，軸承溫度和發動機功率的變化，以確定機器是否正常運行。

　　5.在正常情況下，必須將設備運行1000小時更換潤滑油。注意潤滑油的潤滑是否正常。注意潤滑油的質量。常聽羅茨風機的運行情況，無論有無噪音。注意設備是否在指定的工作條件下運行。

　　6.新機器或改型的羅茨風機將根據使用程序投入運行。建議在運行8小時后更換所有潤滑油。日常維護很重要，在使用之前必須修復故障。

　　必須在操作之前熟讀說明書，保證工作人員把握了設備的有用使用方法。羅茨風機才能進行正確的運轉。

　　羅茨風機壓力降低具體措施：

　　1.風量偏小

　　風量偏小和羅茨風機的間隙也很大的原因，間隙增大，內泄漏嚴重，就會產生風量減小的情況。同樣道理，在輸送氣體的過程中，如果管道出現泄漏，也會產生風量減小的表象。風量偏小還有可能是因為管道阻塞引起，管道阻塞通常與高壓、溫度高并發，為防止管道阻塞的情況，定期檢查羅茨風機的是非常有必要的。

　　2.噪音增大的原因

　　羅茨風機使用的時間過長，整體緊湊性下降，螺栓松動、消音器老化、各個零配件之間間隙誤差增大，造成羅茨風機的噪音越來越大。

　　3.壓力降低

　　羅茨風機壓力降低的主要原因為：間隙增大，葉輪與葉輪之間、葉輪與墻板之間、葉輪與機殼之間間隙增大，羅茨風機為強制性氣體輸送設備，羅茨風機所呈現的壓力為前方阻力，也就是我們常說的背壓。間隙的增大會導致氣體回流嚴重(內泄漏增大)，造成所負壓降低，產生壓力降低的表象。壓力降低的其他原因：密封性降低，不管是羅茨風機還是管道，如果存在有氣體泄漏的情況，都會影響到羅茨風機的壓力值，泄漏嚴重，壓力自然達不到額定標準。

　　Roots blower is a high-speed machine, so it will produce vibration, and because of the pulsation of its internal air, it also increases the vibration of Roots blower, so roots blower needs to be fixed on the ground during installation. According to different fan models, excavate a 150*150mm square 300mm deep square pit on the ground according to the size of the fan, and bury the anchor bolts, then connect the fan through bolts and nuts, and finally fill the square pit with cement concrete. After the concrete is fixed, tighten the nuts with force, so that the fan base and concrete are firmly connected together, so as to reduce the vibration displacement of Roots fan during operation, The operation safety of the equipment is improved, and the service life of the fan is greatly prolonged due to the reduction of vibration.

　　Installation skills and adjustment of Roots blower

　　1. Power cord installation problem

　　When wiring roots blower, it should conform to the rated working voltage of the blower. The voltage used is 380V, and it should not be connected to 220V working voltage. The wires shall not be connected reversely. After being connected reversely, the fan will reverse. If the fan turns incorrectly during the test run, it must be checked. If the check fails, the equipment will be damaged in a short time after the pipes are connected. For example, we once had a customer who failed to detect the test run because the wires were connected reversely, resulting in serious damage to the fan after running for about 10 minutes.

　　2. Installation platform problems

　　Generally speaking, roots fans should be installed on the platform above the ground, but it needs to be determined according to the actual situation. Some small models of roots fans do not need to be fixed, while some models of roots fans must be installed and fixed. Roots fans placed indoors are recommended to be installed according to the actual situation, which can be installed on the platform or on the ground. As for the roots blower placed outside, we suggest to install it on the platform, which can effectively avoid some external erosion.

　　3. Altitude during installation

　　If we have two disposal plants, and the altitude difference between the two places is large, the roots fans between them shall not be used interchangeably. Because the altitude is different, the roots fans of the same model cannot be used interchangeably. When selecting roots blower, we also need to determine the model of Roots blower according to altitude to ensure normal use.

　　4. Switch problems during installation

　　Generally speaking, the switch should not be far away from the equipment. Once the equipment is far away from us, it is inconvenient to control it in case of failure. The longer the failure time is extended, the greater the damage of the equipment is.

　　5. Air flow problems during installation

　　When installing roots blower, it's best not to have strong wind in the surrounding environment. Whether it's upwind or downwind, it will affect the suction and exhaust effect of the equipment. Therefore, controlling the air circulation around the blower can effectively prolong the service life of Roots blower.

　　Roots blower installation:

　　Roots blower is installed before leaving the factory. Only connect the inlet silencer with the inlet, the outlet silencer with the outlet, and then connect the outlet silencer with the pipe. Here are the installation precautions:

　　1. Roots blower shall be installed in a place with solid ground and sufficient space shall be left around for inspection, maintenance and repair.

　　2. The foundation level should be maintained under the roots blower base. It is recommended to pad damping rubber at the four corners of the base or cast and install with bolts to ensure that the roots blower operates smoothly and has little vibration.

　　3. The connecting pipe between Roots fan and system should be sealed reliably. For small vacuum pump, metal pipe connection gasket and oil resistant rubber can be used. For small Roots fan, vacuum rubber pipe connection can be used. The pipe diameter should not be less than the suction diameter of Roots fan, and the pipe should be short and less elbows. (when welding the pipeline, the welding slag in the pipeline should be removed, and it is strictly forbidden for the welding slag to enter the vacuum pump chamber.)

　　4. In the connecting pipeline, users can install valves and vacuum gauges above the air inlet of Roots blower to check the limit pressure of Roots blower at any time.

　　5. Connect the power supply according to the provisions of the motor label, and install the grounding wire and fuse and thermal relay with appropriate specifications.

　　6. When the roots blower is powered on for test run, the motor belt must be removed, and the vacuum pump can be put into use only after confirming that the rotation direction of the vacuum pump meets the specified direction, and the roots blower is used for reverse oil injection. (turn according to the direction indicated by the protective cover)

　　7. For Roots blower with cooling water, connect the cooling water as required.

　　8. If the solenoid valve is installed at the mouth of Roots blower, the valve and roots blower should act at the same time.

　　9. When the exhaust gas of Roots blower affects the working environment, a pipe can be installed at the exhaust port to lead away or install an oil mist filter.

　　Commissioning of Roots blower:

　　Roots blower commissioning includes: inching commissioning, no-load operation commissioning, full pressure commissioning and full system commissioning.

　　1. Inching commissioning refers to completely separating the fan from the system and disconnecting the inlet and outlet pipes of the fan on site. Turn the gear manually. After confirming that there is no jam inside the machine body, start the fan, then turn it off immediately, and then observe whether the rotation direction of the fan is the same as that marked on the machine body. If it is different, for three-phase motors, exchange any two-phase cables and reconnect them. Because the structure of Roots blower cannot be reversed.

　　2. No load operation commissioning refers to starting the fan and running it continuously for half an hour on the premise of inheriting the previous step and confirming the correct rotation direction of the fan, and observing whether the fan operates stably and whether there is abnormal noise and vibration.

　　3. Full pressure test refers to the installation of a valve at the outlet of the fan (to avoid noise, when a silencer is connected behind the valve), after starting the fan, apply a simulated load to the fan by gradually closing the valve until the fan pressure reaches the pressure shown on the nameplate, and then operate continuously for about 2 hours to ensure that the fan has no abnormal sound, The temperature is stable (after the fan is pressurized, the temperature rises gradually, generally as short as half an hour, as long as 2 hours, the temperature tends to stabilize and stops rising. If it continues to rise, there are mostly problems), and the fan current is within the range shown on the nameplate.

　　4. The whole system test refers to connecting the fan into the working system and starting the trial operation, which shall last for more than half an hour. Since the design is generally equipped with design allowance, the pressure and current of the actual operation of the fan after it is connected to the system should be lower than the pressure shown on the nameplate. If there is an overload condition, it often means that the selection is improper, and the problems need to be strictly investigated and analyzed.

　　How to assemble the three blade roots blower? To solve the problem of "assembly", we must first understand the content of assembly.

　　Precautions and steps for assembly of three blade roots blower:

　　1. Precautions during assembly

　　(1) Check whether the disassembled parts are damaged. Pay special attention to the matching parts. If any damage is found, repair or replace it.

　　(2) The bearing should be cleaned and then coated with lubricating oil. When installing the bearing, tools, hands, etc. should be cleaned.

　　(3) Remove the dust from the fitting part, and then apply oil.

　　(4) If the sealing gasket is damaged or lost, replace the gasket with the same thickness and material.

　　2. Assembly steps

　　(1) Install the wall panel (front wall panel) on the drive side onto the housing.

　　(2) Install the impeller part into the casing from the gear end.

　　(3) Install the gear end wall plate on the housing, pay attention to the total axial clearance, and if it is not enough, the housing gasket can be selected.

　　(4) Assemble the front and rear bearings. When assembling the front bearing, the bearing housing should be filled with 1/2-1/3 bearing space grease.

　　(5) Assemble the gear.

　　(6) Install the drive side bearing and locknut together, and install the bearing gland.

　　(7) Adjust the clearance and drive in the locating pin.

　　(8) Install pulley and other parts.

　　Methods to quickly reduce the bearing temperature of three blade roots blower:

　　The bearing temperature of the three leaf roots blower will also be affected by the external environment. In winter, the room temperature is low, and the three leaf roots blower operates well (when the room temperature is 5 ℃, the front bearing of the three leaf roots blower is about 80 ℃). In summer, when the room temperature reaches more than 30 ℃, the front bearing of the three leaf roots blower rises with the room temperature above the set trip temperature. In order to avoid tripping, the crew installed spray water on the casing to cool down as an emergency treatment method, but the sanitary condition during operation is poor. Now several simple and fast methods are recommended.

　　1. Simple and practical is to install sunshades outside the fan, which is one of the direct methods of cooling.

　　2. If the temperature rise of axial flow fan, wear-resistant fan and other fans is too high, it is likely that the inlet and outlet pipe gates are not closed when the fan is started. Solution: Just close the inlet and outlet pipe gates.

　　3. In addition, due to the severe vibration of the box, the installation of the shaft and rolling bearings is skewed, the front and rear bearings are not concentric, and the fan rolling bearings are damaged or the shaft is bent, which are all factors affecting the fan bearing temperature. The solution: lubricate the lubricating oil in time to reduce the friction coefficient.

　　4. The motor belt is too loose. Here, pay attention to replace the motor belt in time, and adjust the position of the pulley to make it stressed evenly.

　　The above are the precautions and steps for the assembly of the three blade roots blower and the method to quickly reduce the bearing temperature.

　　Assembly sequence of Roots blower:

　　Roots blower separates the inlet and outlet with the help of engagement with two impellers, and pushes the gas in the cylinder volume from the inlet to the outlet without internal pressure in the process, so as to achieve the purpose of forced exhaust. Roots blower must be assembled before use, so as to ensure its normal operation.

　　1. Lift the casing onto the workbench, purge and repair burrs.

　　2. Install the wallboard at the drive end on the housing.

　　3. Push the rotor into the housing from the other end.

　　4. Assemble the side wall panel at the gear end; And ensure the total axial clearance. If the total clearance is not enough, the casing gasket can be selected.

　　5. Assemble the bearing seats and bearings on both sides. Determine the axial distribution clearance of the impeller.

　　6. Assemble the gear part and oil slinger. Pay attention to proofreading according to the marked mark. The conical surface of the gear shall not be oiled and shall be cleaned.

　　7. Assemble the gearbox.

　　How to operate roots blower safely:

　　1. Check the tightness of all parts of Roots blower and whether the locating pin is loose. If it is loose, it must be fastened.

　　2. The fan body shall be free of scale, rust and peeling. Prevent leakage.

　　3. When disassembling the machine, please measure the matching size of the machine, record and mark and guide the parts to ensure that the original matching requirements are assembled and maintained.

　　4. Sometimes the overload of Roots blower cannot be displayed immediately, so please pay attention to the changes of inlet and exhaust pressure, bearing temperature and engine power to determine whether the machine operates normally.

　　5. Under normal conditions, the equipment must be operated for 1000 hours to change the lubricating oil. Pay attention to whether the lubrication of lubricating oil is normal. Pay attention to the quality of lubricating oil. Always listen to the operation of Roots blower, whether there is noise or not. Pay attention to whether the equipment operates under the specified working conditions.

　　6. The new machine or modified roots blower will be put into operation according to the use procedure. It is recommended to replace all lubricating oils after 8 hours of operation. Routine maintenance is very important, and the fault must be repaired before use.

　　You must read the instructions carefully before operation to ensure that the staff grasp the useful use method of the equipment. Roots blower can operate correctly.

　　Specific measures for pressure reduction of Roots blower:

　　1. The air volume is too small

　　The air volume is too small and the gap of Roots blower is also very large. If the gap increases and the internal leakage is serious, the air volume will decrease. Similarly, in the process of transporting gas, if the pipeline leaks, it will also produce the appearance of reduced air volume. The low air volume may also be caused by pipe blockage, which is usually accompanied by high pressure and high temperature. In order to prevent pipe blockage, it is very necessary to regularly check the operation of Roots blower.

　　2. Causes of noise increase

　　The roots blower has been used for a long time, the overall compactness has decreased, the bolts have become loose, the silencer has aged, and the gap error between various parts has increased, resulting in the increasing noise of the roots blower.

　　3. Pressure reduction

　　The main reasons for the pressure reduction of Roots blower are: the gap increases, and the gap between impellers, between impellers and wallboards, and between impellers and casings increases. Roots blower is a mandatory gas transmission equipment, and the pressure presented by roots blower is the front resistance, that is, the back pressure we often say. The increase of gap will lead to serious gas backflow (increased internal leakage), resulting in the reduction of negative pressure and the appearance of pressure reduction. Other reasons for pressure reduction: the tightness is reduced. If there is gas leakage in Roots blower or pipeline, it will affect the pressure value of Roots blower. The leakage is serious, and the pressure naturally cannot reach the rated standard.
