常見的羅茨風機出口壓力波動分為兩種情況：一種是壓力過高，另一種是壓力過低!在這兩種情況中，無論是出現了哪一種，都會對工廠的產能造成一定的損失!因此，我們通常建議長期運轉羅茨風機的客戶采用用一備一的方法!以便在羅茨風機出現問題后，及時啟動備用鼓風機解決臨時的生產需求!特別是羅茨風機已經連續運轉5年以上的客戶，要時刻關注羅茨鼓風機的運轉狀態，定時進行羅茨鼓風機維護保養!下面回歸正題，我們一起來探討一下羅茨鼓風機出口壓力波動問題!首先是羅茨鼓風機壓力過高怎么辦?

　　羅茨鼓風機出口壓力過高的原因：

　　1.羅茨鼓風機的壓力取決于它所承受的阻力。只要在可接受的壓力范圍內，它就能正常工作。比如你給一個水深2米的水池充氣，空氣壓力是20000帕。在一個3米深的池塘里，它變成了30000帕。只要電機的輸出功率能達到負載。

　　2.如果壓力表指示的壓力大于應輸出的壓力，則可能是管道堵塞、曝氣頭堵塞等造成的。

　　電機電流大的原因是羅茨鼓風機：

　　1.與規定壓力相比，壓差較大，即背壓或入口壓力較大且較高。

　　2.與設備要求的流量相比，風機流量過大，壓力增大。

　　3.入口過濾器堵塞，出口管堵塞。

　　4.接觸和摩擦旋轉部件(卡住)。

　　解決羅茨鼓風機出口壓力過大的方法：

　　1.將壓力降低到指定值。

　　2.向大氣排放過量氣體或降低鼓風機速度。

　　3.清除障礙。

　　4.立即停車，檢查原因。

　　5.將油位調整到正確的位置。

　　6.檢查皮帶張力，用大直徑皮帶輪更換。

　　知道了羅茨鼓風機出口壓力大的解決方法，如果遇到羅茨鼓風機出口壓力低的波動時，該怎么解決呢?

　　通常，羅茨鼓風機壓力降低的主要原因是間隙增大、葉輪與葉輪、葉輪與墻板、葉輪與殼體之間的間隙增大。羅茨鼓風機是一種強制性氣體輸送設備，羅茨鼓風機的壓力是前阻力，通常稱為背壓。間隙增大會導致氣體回流嚴重(內泄漏增大)，導致負壓降低，壓力降低。壓力降低的其他原因：無論是羅茨鼓風機還是管道，如果有氣體泄漏，都會影響羅茨鼓風機的壓力值，泄漏嚴重，壓力自然不能達到額定標準。

　　羅茨鼓風機壓力降低往往是由其他故障引起的。在使用過程中，如果壓力降低過大，應及時檢查和修復，以確保羅茨鼓風機的正常運行。

　　1.噪聲擴大的原因。

　　羅茨鼓風機已經使用了十年，整體緊湊型降低，地腳螺栓松動，消聲器脆化，各部件之間的間隙偏差擴大，導致羅茨鼓風機的噪聲越來越大。

　　2.減少工作壓力。

　　羅茨鼓風機工作壓力下降的關鍵原因是：間隙擴大、離心葉輪與離心葉輪中間、離心葉輪與板墻中間、離心葉輪與殼體之間的間隙擴大。羅茨鼓風機是一種強制蒸汽輸送機械設備。羅茨鼓風機顯示的工作壓力為前摩擦阻力，通常稱為蒸汽。間隙的擴大會導致汽體流回嚴重(內泄漏擴大)，導致空氣壓力降低，工作壓力降低。

　　工作壓力降低的其他原因：密封性降低，無論羅茨鼓風機是管道，如果有氣體泄漏，都會損害羅茨鼓風機的工作壓力值，泄漏更嚴重，當然，工作壓力不能達到額定值規范。

　　3.排氣量小。

　　由于排氣量小，羅茨鼓風機間隙大，間隙擴大，內部泄漏嚴重，排氣量減少。同樣，在汽車運輸的整個過程中，如果管道泄漏，也會導致排氣量減少。

　　排氣量小也可能是由管道堵塞引起的。管道堵塞一般采用高壓和溫度分布式系統。為了避免管道堵塞，有必要定期維護羅茨鼓風機。

　　The common fluctuation of outlet pressure of Roots blower can be divided into two situations: one is too high pressure, the other is too low pressure! In both cases, no matter which one occurs, it will cause a certain loss of factory capacity! Therefore, we usually recommend that customers who run Roots fans for a long time adopt a one-for-one approach! In order to start the standby blower in time to solve the temporary production demand after the Roots blower has problems! In particular, customers who have been running Roots blower for more than 5 years should always pay attention to the operation state of Roots blower and carry out regular maintenance of Roots blower! Let's get back to business and discuss the pressure fluctuation at the outlet of Roots blower. First, what if the Roots blower pressure is too high?

　　Reasons for high outlet pressure of Roots blower:

　　1.The pressure of a Roots blower depends on the resistance it is subjected to. It will work as long as it is within acceptable pressure range. For example, if you inflate a pool 2 meters deep, the air pressure is 20,000 Pa. In a pond 3 meters deep, it turned into 30,000 Pa. As long as the output power of the motor reaches the load.

　　2. If the pressure indicated by the pressure gauge is higher than the pressure to be output, it may be caused by pipe blockage, aerator blockage, etc.

　　The reason for the high motor current is the Roots blower:

　　1. Compared with the specified pressure, the pressure difference is larger, i.e. the back pressure or inlet pressure is larger and higher.

　　2. Compared with the flow required by the equipment, the flow of fan is too large and the pressure increases.

　　3.The inlet filter is blocked and the outlet pipe is blocked.

　　4.Contact and friction rotating parts (stuck).

　　Solutions to excessive outlet pressure of Roots blower:

　　1.Reduce pressure to specified value.

　　2. Discharge excess gas to the atmosphere or reduce the speed of the blower.

　　3. Remove barriers.

　　4.Stop immediately and check the cause.

　　5.Adjust the oil level to the correct position.

　　6.Check belt tension and replace with large diameter pulley.

　　Know how to solve the problem of high outlet pressure of Roots blower, if encounter fluctuation of low outlet pressure of Roots blower, how to solve it?

　　Generally, the main reasons for the pressure reduction of Roots blower are the increased clearance between impeller and impeller, between impeller and wall plate, and between impeller and housing. Roots blower is a mandatory gas delivery equipment. The pressure of Roots blower is front resistance and is commonly referred to as back pressure. Increased clearance will result in severe gas reflux (increased internal leakage), resulting in lower negative pressure and lower pressure. Other causes of pressure drop: whether a Roots blower or a pipe, if there is a gas leak, it will affect the pressure value of the Roots blower. The leakage is serious and the pressure can not meet the rated standard.

　　Reduced Roots blower pressure is often caused by other faults. During use, if the pressure drops too much, it should be inspected and repaired in time to ensure the normal operation of Roots blower.

　　1. Reasons for increased noise.

　　Roots blower has been in service for ten years, with reduced overall compactness, loosened anchor bolts, brittle muffler and widened gap deviation between components, resulting in increased Roots blower noise.

　　2.Reduce work stress.

　　The key reasons for the decrease of working pressure of Roots blower are the enlarged gap, the middle between centrifugal impeller and centrifugal impeller, the middle between centrifugal impeller and plate wall, and the enlarged gap between centrifugal impeller and housing. Roots blower is a forced steam transfer mechanical equipment. Roots blowers display a working pressure of front friction resistance, commonly referred to as steam. The enlargement of the clearance results in a severe return of the vapor body (enlarged internal leakage), resulting in lower air pressure and lower working pressure.

　　Other causes of reduced working pressure: reduced sealing, regardless of whether the Roots blower is a pipe, if there is a gas leak, the working pressure value of the Roots blower will be impaired and the leak will be more serious. Of course, the working pressure can not meet the rated specifications.

　　3.Small exhaust volume.

　　Due to small exhaust volume, large clearance, enlarged clearance, serious internal leakage and reduced exhaust volume of Roots blower. Likewise, leakage of pipes throughout the entire vehicle transportation process can also lead to a reduction in exhaust emissions.

　　Low exhaust may also be caused by pipe blockage. High pressure and temperature distributed systems are generally used for pipe blockage. To avoid pipe blockage, regular maintenance of the Roots blower is necessary.

　　Above is the solution of Roots blower manufacturer and environmental protection summary of Shanghai Ruizhi [Roots blower outlet pressure fluctuation]! Each Roots blower customer can solve the problem of pressure fluctuation at the outlet of Roots blower according to their own actual situation.
