常见的罗茨风机出口压力波动分为两种情况：一种是压力过高，另一种是压力过低!在这两种情况中，无论是出现了哪一种，都会对工厂的产能造成一定的损失!因此，我们通常建议长期运转罗茨风机的客户采用用一备一的方法!以便在罗茨风机出现问题后，及时启动备用鼓风机解决临时的生产需求!特别是罗茨风机已经连续运转5年以上的客户，要时刻关注罗茨鼓风机的运转状态，定时进行罗茨鼓风机维护保养!下面回归正题，我们一起来探讨一下罗茨鼓风机出口压力波动问题!首先是罗茨鼓风机压力过高怎么办?

　　罗茨鼓风机出口压力过高的原因：

　　1.罗茨鼓风机的压力取决于它所承受的阻力。只要在可接受的压力范围内，它就能正常工作。比如你给一个水深2米的水池充气，空气压力是20000帕。在一个3米深的池塘里，它变成了30000帕。只要电机的输出功率能达到负载。

　　2.如果压力表指示的压力大于应输出的压力，则可能是管道堵塞、曝气头堵塞等造成的。

　　电机电流大的原因是罗茨鼓风机：

　　1.与规定压力相比，压差较大，即背压或入口压力较大且较高。

　　2.与设备要求的流量相比，风机流量过大，压力增大。

　　3.入口过滤器堵塞，出口管堵塞。

　　4.接触和摩擦旋转部件(卡住)。

　　解决罗茨鼓风机出口压力过大的方法：

　　1.将压力降低到指定值。

　　2.向大气排放过量气体或降低鼓风机速度。

　　3.清除障碍。

　　4.立即停车，检查原因。

　　5.将油位调整到正确的位置。

　　6.检查皮带张力，用大直径皮带轮更换。

　　知道了罗茨鼓风机出口压力大的解决方法，如果遇到罗茨鼓风机出口压力低的波动时，该怎么解决呢?

　　通常，罗茨鼓风机压力降低的主要原因是间隙增大、叶轮与叶轮、叶轮与墙板、叶轮与壳体之间的间隙增大。罗茨鼓风机是一种强制性气体输送设备，罗茨鼓风机的压力是前阻力，通常称为背压。间隙增大会导致气体回流严重(内泄漏增大)，导致负压降低，压力降低。压力降低的其他原因：无论是罗茨鼓风机还是管道，如果有气体泄漏，都会影响罗茨鼓风机的压力值，泄漏严重，压力自然不能达到额定标准。

　　罗茨鼓风机压力降低往往是由其他故障引起的。在使用过程中，如果压力降低过大，应及时检查和修复，以确保罗茨鼓风机的正常运行。

　　1.噪声扩大的原因。

　　罗茨鼓风机已经使用了十年，整体紧凑型降低，地脚螺栓松动，消声器脆化，各部件之间的间隙偏差扩大，导致罗茨鼓风机的噪声越来越大。

　　2.减少工作压力。

　　罗茨鼓风机工作压力下降的关键原因是：间隙扩大、离心叶轮与离心叶轮中间、离心叶轮与板墙中间、离心叶轮与壳体之间的间隙扩大。罗茨鼓风机是一种强制蒸汽输送机械设备。罗茨鼓风机显示的工作压力为前摩擦阻力，通常称为蒸汽。间隙的扩大会导致汽体流回严重(内泄漏扩大)，导致空气压力降低，工作压力降低。

　　工作压力降低的其他原因：密封性降低，无论罗茨鼓风机是管道，如果有气体泄漏，都会损害罗茨鼓风机的工作压力值，泄漏更严重，当然，工作压力不能达到额定值规范。

　　3.排气量小。

　　由于排气量小，罗茨鼓风机间隙大，间隙扩大，内部泄漏严重，排气量减少。同样，在汽车运输的整个过程中，如果管道泄漏，也会导致排气量减少。

　　排气量小也可能是由管道堵塞引起的。管道堵塞一般采用高压和温度分布式系统。为了避免管道堵塞，有必要定期维护罗茨鼓风机。

　　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]!
