答：在行業中，將羅茨風機壓力過高的情況稱之為“超壓”!通常在使用羅茨鼓風機氣力輸送的過程中，如果管道由于某些原因被阻塞并且阻力增加，則很可能導致羅茨風機超壓。如果超壓太大，將產生氣體。逆流和此時的止回閥可以確保羅茨風機的安全。 當氣體反轉時，單向閥關閉以防止氣體倒流。此時，羅茨風機將由于超壓過載而增加電壓和電流，同時，泄壓閥將開始放氣，壓力將保持在相對平衡的邊界。

　　萬一出現超壓，羅茨風機會有一系列癥狀。風量不足、振動加大，產生噪音，出現異響等，會無法工作。對于這些情況，我們應及時找出原因，以免發生事故。

　　羅茨風機的止回閥需要與其他零件配合才能發揮良好的作用，特別是當氣體換向時，羅茨風機的止回閥處于半關閉狀態，此時羅茨的其他零件 鼓風機，如：泄壓閥，排氣閥等，這種逆流情況存在時間很長，這些部件可以起到良好的協同作用。

　　羅茨風機通過轉子軸端的同步齒輪使兩個轉子保持嚙合。轉子的每個凹曲面部分和氣缸的內壁形成工作空間，并且在轉子旋轉期間將氣體從吸氣口帶走，羅茨風機移至排氣口附近 由于高壓氣體返回，因此與排氣口連通，這時羅茨風機的工作容積中的壓力突然升高，然后將氣體輸送到排氣通道。兩個轉子不相互接觸，并且通過緊密控制的間隙將它們密封，因此排出的氣體不會被潤滑油污染。下面是我們整理總結的羅茨風機超壓的原因與解決方法分享給大家：

　　1.羅茨鼓風機的壓力取決于它受到的阻力。只要在可接受的壓力范圍內，它就能正常工作。例如，如果你給一個水深2米的水池充氣，吹出的空氣壓力是20千帕。在3米深的池塘里，它變成30千帕。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，可能是管道堵塞、曝氣頭堵塞等造成的。

　　羅茨鼓風機引起電機電流大的原因：

　　1.與規定壓力相比，壓差較大，即背壓或入口壓力大且高。

　　2.與設備要求流量相比，風機流量太大，壓力增加。

　　3.入口過濾器堵塞，出口管道堵塞。

　　4.轉動部件接觸和摩擦(卡住。

　　解決風機壓力過大的方法：

　　1.將壓力降低至規定值。

　　2.將過量氣體排入大氣或降低鼓風機速度。

　　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，并用大直徑皮帶輪更換。

　　In industry, the condition of excessive pressure of Roots blower is called "overpressure"! Often during pneumatic conveying with a Roots blower, overpressure of the Roots blower is likely to occur if the piping is blocked for some reason and resistance increases. If the overpressure is too high, gas will be produced. Backflow and check valves at this point ensure the safety of the Paulz blower. When the gas reverses, the check valve closes to prevent the gas from backflowing. At this point, the Roots blower will increase voltage and current due to overpressure overload, while the relief valve will begin to bleed and the pressure will remain at a relatively balanced boundary.

　　In the event of overpressure, the Roots blower will have a series of symptoms. Insufficient air volume, increased vibration, noise, abnormal noise, etc., will not work. In these cases, we should find out the cause in time to avoid accidents.

　　Check valves of Roots blowers need to work well with other parts, especially when gas is reversed, the check valves of Roots blowers are in a semi-closed state. At this time, other parts of Roots blowers, such as pressure relief valves, exhaust valves, etc., have a long history of countercurrent, and these parts can play a good synergy.

　　The Roots blower compressor keeps the two rotors engaged by means of synchronous gears at the rotor shaft end. Each concave-curved part of the rotor forms a working space with the inner wall of the cylinder and takes the gas away from the suction port during the rotor rotation. The Roots blower moves to the vicinity of the exhaust port and is connected to the exhaust port because of the return of high-pressure gas. At this point, the pressure in the working volume of the Roots blower suddenly rises and the gas is then conveyed to the exhaust passage. The two rotors are not in contact and are sealed by tightly controlled clearances so that the exhaust gas is not contaminated by lubricating oil. Following is the reason and solution for overpressure of Roots blower summarized by us to share with you:

　　1.The pressure of a Roots blower depends on the resistance it receives. 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 will be 20 kPa. In a pond 3 meters deep, it becomes 30 kPa. 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.

　　Reasons for high motor current caused by Roots blower:

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

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

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

　　4.Turning parts contact and friction (stuck).

　　Solutions to excessive fan pressure:

　　1. Reduce pressure to specified value.

　　2. Drain excess gas into 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.
